THURSDAY, JANUARY 30, 2003
Most of the 80 experiments already have completed their data collection, and today was the last day for the remaining investigations, in particular the Water Mist Fire Suppression Experiment (MIST), the Mediterranean Israeli Dust Experiment (MEIDEX) and the Advanced Respiratory Monitoring System (ARMS).
MIST, which got a late start due to problems setting up the test chamber, is nearing its 30th run as it studies the effectiveness of fog-like water droplet concentrations in putting out flames. The experiment is sponsored by the Center for Commercial Applications of Combustion in Space at the Colorado School of Mines in Golden as part of continuing program to design replacements for environmentally hazardous chemicals such as Halons.
MEIDEX will be recording its final data takes of lightning "sprites" and "elves," after successfully imaging a major dust concentration in support of its primary objective to study how fine dust particles, or aerosols, affect the Earth's environment. MEIDEX was sponsored by the Israeli Space Agency and Tel-Aviv University in association with Payload Specialist Ilan Ramon's first space flight for an Israeli.
Crewmembers also began wrapping up and storing the final blood, urine and saliva samples they are providing for studies of human physiology associated with the ARMS cardiovascular experiments and the Physiology and Biochemistry Team experiments. The samples will be kept at appropriate temperatures in refrigeration systems in the Spacehab module for return to Earth and further study.
And the Biotube experiment, which was activated Wednesday, looked at flax seeds as they grew in the presence of strong magnetic field. Scientists on the ground used video downlinks to monitor the length of root growth to ensure appropriate fixation times.
Commander Rick Husband and Flight Engineer Kalpana Chawla of the day shift took turns simulating landing on the PILOT computer-based training system. Pilot Willie McCool of the night shift will get in his practice session overnight. Landing is scheduled for 9:16 a.m. EST Saturday and preliminary forecasts show excellent conditions at the Shuttle Landing Facility in Florida. If weather decides not to cooperate, there are plenty of supplies to support the crew until conditions are favorable.
Husband also peeked under the floor of the Spacehab module to look for water that might have leaked out of the balky air-conditioning system earlier in the mission. He reported finding no moisture that could contaminate Spacehab systems if jostled during Saturday's re-entry and landing, but covered several holes in the water sub-assembly with tape as a precaution.
WEDNESDAY, JANUARY 29, 2003
Commander Rick Husband, Pilot Willie McCool, Mission Specialists Dave Brown, Kalpana Chawla, Michael Anderson and Laurel Clark, and Israel Space Agency Payload Specialist Ilan Ramon fielded questions about how their shuttle was performing as a research laboratory, their work in support of the STS-107 mission's 80 different experiments and preparations for Saturday's planned landing.
"The science we're doing here is great and it's fantastic," said Anderson, the payload commander, "it's leading edge. But I think once we get a seven-member crew on board the space station you're really going to see some outstanding science in space. A lot of experiments that we have are really just being demonstrated and developed. Once they're fully developed they'll reside on board the space station and the scientists ä will have years to conduct the experiments that we're trying to do here in a relatively short period of time."
Ramon reported that dust storms off the east coast of Africa were scarce for the first week of the flight, but that a giant dust storm kicked up over the Atlantic and lasted three days, providing ample observations for the Mediterranean Israeli Dust Experiment. He voiced wishes for peace in his area of the world from 180 miles above.
"The world looks marvelous from up here, so peaceful, so wonderful and so fragile," Ramon said. "The atmosphere is so thin and fragile, and I think all of us have to keep it clean and good. It saves our life and gives our life."
After a 3:39 p.m. EST Blue Team wake-up to the sounds of John Lennon singing "Imagine," McCool and Ramon said their observations from orbit reveal no borders on the Earth below and reiterated in both English and Hebrew their hopes for peace in the world.
Initial tests in the Combustion Module Facility with the newly revitalized Water Mist Fire Suppression Experiment took center stage today, with 14 sample runs completed after Chawla fixed a balky seal in the combustion module yesterday. Another 20 runs are planned before the end of the mission on tests designed to learn exactly how the water interacts with flames as it is extinguishing them.
TUESDAY, JANUARY 28, 2003
Mission Specialist Kalpana Chawla reported a good leak check of the Combustion Module-2 Facility about 5 p.m. EST after five hours of work. She and Commander Rick Husband sent down video of the recovery procedures for the Water Mist Fire Suppression Experiment (MIST) around 3 p.m. to give engineers on the ground an opportunity to visually inspect the equipment. The combustion facility, which provides control, containment, diagnostics and communications for fire-related experiments, worked flawlessly in support of the two previous combustion experiments, but failed its initial leak checks when MIST was installed Monday.
Payload Commander Michael Anderson of the Blue team is scheduled to begin work with the MIST experiment overnight. Designed by the Center for Commercial Applications of Combustion in Space at the Colorado School of Mines, Golden, Colo., the experiment will investigate how water mist inhibits the spread of flames. Scientists hope to apply what they learn to designs for improved, lighter-weight fire suppression systems on Earth, as well as for spacecraft-based systems that won't require ozone-damaging chemicals such as Halons.
Husband, Chawla and Red team colleagues Laurel Clark and Ilan Ramon enjoyed some time off for the first half of their day, then moved ahead with other experiments in the Spacehab Research Double Module. Clark retrieved samples associated with the Bioreactor Demonstration System, which Project Scientist Tom Goodwin reported today has grown a bone and prostate cancer tumor tissue sample as large as a golf ball, the largest grown in space to date. She also collected blood and urine samples from her crewmates for the Physiology and Biochemistry (PhAB4) suite of experiments. Ramon also conducted observations of dust off the African coast for the Mediterranean Israeli Dust Experiment (MEIDEX).
After a 3:39 p.m. EST wake-up to the Beach Boys singing "I Get Around," the Blue team of Anderson, Pilot Willie McCool and Mission Specialist Dave Brown resumed work with the tests of their breathing, hearts and muscle associated with Advanced Respiratory Monitoring System. Anderson was scheduled to check on the condition of the animals on board, which has continued to be good.
MONDAY, JANUARY 27, 2003
The Structures of Flame Balls experiment, looking at ways of improving engine combustion efficiency, was shut down after a total of 39 tests using 15 different fuel mixtures. A total of 55 flame balls were ignited, including the weakest and leanest flames ever burned. The longest-lived flame burned in space for 81 minutes, part of a total burn time for all flames of 6 1/4 hours. Oscillating (shrinking and growing) flame balls, which had been predicted theoretically, were observed for the first time.
The Mechanics of Granular Materials test, looking for ways to better understand and deal with soil movement associated with earthquakes, completed its 10th and final run. The Microbial Physiology Flight Experiment expended its eighth and final set of samples looking at yeast and bacteria growth in microgravity. The Canadian-developed Osteoporosis in Orbit also completed its operations.
The Red team, or day shift -- Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark and Israel Space Agency Payload Specialist Ilan Ramon -- took time out from microgravity experimentation about 12:30 p.m. EST to chat with the other three spacefarers on orbit -- Commander Ken Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer Nikolai Budarin. At the time, the space station was some 240 miles above Southern Russia while the shuttle was over northern Brazil.
The Expedition Six crew aboard the station concentrated on loading new software on the EXPRESS experiment racks, working with Russian and American experiments and preparing the old Progress for its undocking this week to make room for a new supply craft, scheduled to launch Feb. 2 from the Baikonour Cosmodrome in Khazakstan and dock with the station Feb. 4.
After a 3:39 p.m. EST wake-up to the sounds of "Slow Boat to Rio" by Earl Klugh, the Blue team of astronauts -- Payload Commander Michael Anderson, Mission Specialist Dave Brown and Pilot Willie McCool was scheduled to enjoy half a day of rest before resuming research activities concentrating on the Mediterranean Israeli Dust Experiment, which yesterday captured its first observations of dust over the Atlantic. Scientists with the Israel Space Agency reported that preliminary data looks promising.
SUNDAY, JANUARY 26, 2003
The Red team of astronauts, working by day, and the Blue team, working by night, maintained a round-the-clock presence in the SPACEHAB Double Research Module, tending to dozens of experiments as scientists reported excellent results. Temperatures in SPACEHAB were maintained at a comfortable 73 degrees, despite the loss of two dehumidifiers earlier in the mission. All of the animals involved in life science experiments were reported to be in good shape along with SPACEHAB hardware.
Red team crewmembers Rick Husband, who is Columbia's Commander, Mission Specialists Kalpana Chawla and Laurel Clark and Israeli Payload Specialist Ilan Ramon conducted more experiments involving the study of flames in space in a special Combustion Module in the SPACEHAB.
More investigations were conducted into the effect of dust storms on the atmosphere with multispectral cameras in Columbia's cargo bay. The MEIDEX experiment focused on plumes of dust in the Mediterranean region and in the Middle East as well as sprites in the targeted areas of interest. Science controllers reported the first successful digital downlink of imagery from the experiment as well as the observance of significant amounts of dust in the observed regions.
A suite of student experiments called STARS yielded the hatching of a fish in an aquatic facility and the successful emergence of a silk moth from its cocoon. STARS contains a half dozen student developed experiments ranging from the study of Australian spiders to the analysis of spaceflight's effects on carpenter bees from Liechtenstein.
The Biopack experiment involving the study of weightlessness on biological samples continued to produce what was described as excellent data for its team of researchers despite the loss of freezer and incubator capability for the storage of samples.
Blue team crewmembers Willie McCool, who is Columbia's Pilot, Payload Commander Mike Anderson and Mission Specialist Dave Brown were awakened for their night shift shortly after 3:30 p.m. EST. They planned to conduct final combustion studies with the SOFBALL experiment tonight after which the Combustion Module will be reconfigured for the Water Mist experiment, studying fire suppression techniques in spaceflight.
The Blue team will spend some time refreshing water for 13 rodents in the Animal Enclosure Module in SPACEHAB. Data is being acquired on the effect of microgravity on the rodents' neurovestibular system. Now that SPACEHAB temperatures have cooled again, sound mufflers were reinstalled on the animal enclosure compartments.
More data will also be received tonight from the SOLSE experiment, which uses imaging devices in the shuttle's cargo bay to study the Earth's ozone layer. Earlier today, the crew downlinked digital video of the Middle East with breathtaking views of Israel, the Red Sea and the Sinai Peninsula. The video also contained scenes of life and work on orbit involving the seven astronauts. Columbia's systems continue to function perfectly as the shuttle orbits at an altitude of about 180 statute miles.
Flying slightly higher, the Expedition 6 crew aboard the International Space Station is now in its 10th week in space. Commander Ken Bowersox, Flight Engineer Nikolai Budarin and NASA ISS Science Officer Don Pettit spent a quiet Sunday, enjoying the views of Earth from orbit while conducting a minor maintenance procedure involving a hatch window in the Unity module. Station systems are also functioning normally.
The space travelers aboard Columbia and the ISS will have a chance to talk to one another Monday in a brief ship-to-ship hookup scheduled at 12:34 p.m. EST. At the time of the ship-to-ship call, Columbia will be orbiting over northern Brazil, while the ISS sails over southern Russia.
SATURDAY, JANUARY 25, 2003
Toward the end of their workday at 2 a.m. EST this morning, Pilot Willie McCool and Mission Specialists Dave Brown and Michael Anderson of the Blue Team took time out from their experiment schedule for interviews with reporters from Black Entertainment TV, WTKR-TV in Norfolk, Va., and KNSD-TV in San Diego. Following handover talks, Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark, and Payload Specialist Ilan Ramon of the Red Team began their workday.
Clark completed operations with the OSTEO (Osteoporosis Experiment in Orbit) investigation for STS-107. The experiment studied the activity of bone cells in microgravity by looking at normal activity and activity under the influence of various drugs. Clark also continued work on the Bioreactor Demonstration System, which is using the NASA-developed bioreactor to grow prostate cancer tissues. The objective is to learn how the cancer spreads into bones and aid in the development of future treatment methods. She also worked on a study of how bacteria and yeast develop in space and how microgravity affects their response to antibiotics.
Investigations with the Combined Two-Phase Loop Experiment were begun using a third cooling loop. Testing of this loop will continue for about 48 hours. The testing is performed to learn about the behavior of the loop in microgravity. The investigation examines three different two-phase thermal loops by transporting different amounts of heat from an evaporator to a condenser and then radiating the heat into space.
The Facility for Adsorption and Surface Tension, known as FAST, has completed the last pre-planned sequence of experiments. It is designed to measure the response of surface tension to carefully controlled changes in the surface areas of bubbles or droplets.
Ramon continued investigations with the SOFBALL (Structures of Flame Balls) experiment. The experiment studies lean combustion to help engineers design engines with better fuel efficiency and reduced emissions of pollution.
Television from the crew, narrated by Ramon, was downlinked around 12:30 p.m. showing various aspects of experiment operations conducted by both teams. Husband maneuvered Columbia today as required for any scientific activities.
McCool, Brown and Anderson were awakened at 3:39 p.m. to the sounds of "I Say a Little Prayer for You" sung by Dionne Warwick. The song was played for Anderson from his wife.
Husband ended his 10th day in space by calibrating two Israeli cameras that will be used to continue photographing dust particles, sprites and other electrical phenomena in the upper atmosphere. The crew hope to use the camera to observe a substantial plume of dust and smoke that extends from the Nigerian coast westward toward the Atlantic and an additional plume off the coast of Mauritania and Mali. Sprites in storms over Western Australia near Perth also will be observed. Sprites are electrical discharges that shoot up from the tops of thunderstorms into the Earth's ionosphere.
All of Columbia's systems continue to operate in excellent shape.
It was a quiet day on board the International Space Station, meanwhile, as Expedition 6 Commander Ken Bowersox, Flight Engineer Nikolai Budarin and ISS Science Officer Don Pettit enjoyed a light workday. They will also partake in an off-duty day tomorrow before resuming normal scientific research and routine station maintenance activities on Monday.
FRIDAY, JANUARY 24, 2003
Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark, and Payload Specialist Ilan Ramon of the Red Team began their workday about 6 a.m. EST, focusing again on work with the SOFBALL (Structures of Flame Balls) experiment and the ARMS (Advanced Respiratory Monitoring System) human physiology experiment. Husband maneuvered Columbia into the proper positions for the various experiments.
The two teams have completed seven SOFBALL runs so far, including the first of several using methane as a fuel, which is visible to the naked eye as a faint blue flame. This evening, the Blue Team will attempt the longest planned test, lasting 2 hours, 47 minutes, while the shuttle is placed in a "free drift" configuration to eliminate thruster firings that could affect the test.
Pilot Willie McCool and Mission Specialists Dave Brown and Michael Anderson of the Blue Team were awakened about 3:30 p.m. to the sounds of "Hotel California" performed by members of McCool's family. Their duty shift was scheduled to begin about 6 p.m. after a pre-bedtime handover from the Red Team.
The Blue Team also will resume work with the Mechanics of Granular Materials experiment, looking at how sandy soil full of water behaves under pressure. Three compressions are planned over the next two days, with a final run set for later in the mission.
The study of spiral moss growth in space completed a set of time-critical fixations on several sets of moss plants, so that their growth rates can be established after the flight. Four more fixations are planned. The Astroculture experiment harvested the last of its six samples of essential oils from rose and rice flowers, which could eventually result in new perfume fragrances. Checks of all of the insects, spiders and animals aboard Columbia showed that all are healthy in their enclosures.
Flight controllers and the crew continue to manage temperatures in the Spacehab Research Double Module by periodically adjusting cooling loop settings. Columbia is in good shape, orbiting at an altitude of 180 statute miles.
THURSDAY, JANUARY 23, 2003
Highlighting the investigations today for both the Blue and Red Teams were the SOFBALL (Structures of Flame Balls) and ARMS (Advanced Respiratory Monitoring System) experiments, although both teams continued to support other experiments with a variety of activities.
Mission Specialists Michael Anderson of the Blue Team and Kalpana Chawla of the Red Team initiated runs with the SOFBALL experiment, which is creating tiny ball-shaped flames using hydrogen as the fuel. The tiny flames, which are approaching some of the leanest and longest-lasting ever, are invisible to the human eye but visible to the crew and investigators on the ground through special video equipment. Dr. Paul Ronney of the University of Southern California and his team hope to discover new properties about combustion to improve engine efficiency and fire safety, as well as reduce emissions.
Mission Specialist Dave Brown of the Blue Team and Israeli Payload Specialist Ilan Ramon of the Red Team concentrated on the Advanced Respiratory Monitoring System. The European Space Agency experiment alternated experiments targeting the human lung and circulatory system and the human muscular system as it looked at changes brought on by weightlessness.
Commander Rick Husband, leader of the Red Team, and Pilot Willie McCool, leader of the Blue Team, adjusted Columbia's attitude relative to the Earth to support the different requirements of the experiments. They continued to manage the temperature inside the Spacehab Research Double Module in the wake of problems incurred with cooling systems. No experiments have or are expected to be affected by the cooling issue.
Red Team Mission Specialist Laurel Clark, a medical doctor, worked with the Bioreactor Demonstration System, which is growing tissue samples as part of a prostate cancer study. She also beamed down data from the Astroculture experiment growing roses and rice flowers for commercial fragrance development. Clark also worked with bacteria and yeast cultures being grown as part of a Microbial Physiology Flight Experiment that looks at the effect of microgravity on antibiotics.
In honor of the combustion experiments on this flight, the Blue Team's wake-up call this afternoon was "Burning Down the House," by the Talking Heads.
Aboard the International Space Station, Expedition 6 Commander Ken Bowersox, Flight Engineer Nikolai Budarin and ISS Science Officer Don Pettit spent their 61st day in space and their 59th day on the station practicing techniques with the Canadarm2 robot arm. This activity was in preparation for the March mission of Atlantis to the ISS that will involve a variety of uses for the space crane.
Columbia and the ISS are both operating in normal fashion, with the Shuttle orbiting at an altitude of 180 statute miles in an orbit inclined 39 degrees to either side of the equator and the station orbiting at an altitude of 240 statute miles in an orbit inclined 51.6 degrees to either side of the equator
WEDNESDAY, JANUARY 22, 2003
The television pictures showed ants busily creating and moving about tunnels in an ant farm developed by students from Fowler High School in Syracuse, N.Y.; Garden Orb Weaver spiders beginning to construct webs in an enclosure designed by students at Glen Waverly Secondary College of Melbourne, Australia; silkworm larvae beginning to develop in an experiment designed by students at Jingshan School, Beijing, China; Medaka fish embryos developing in a tank designed by students at the Tokyo Institute of Technology in Tokyo; and carpenter bees beginning to construct nests by boring tunnels in wood.
The experiments are being monitored by both teams of astronauts as they work in shifts to support the 80 different experiments aboard the space shuttle and the Spacehab Research Double Module. The Red Team -- Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark and Israel Space Agency Payload Specialist Ilan Ramon ‚ enjoyed a half-day off before resuming work with a variety of other experiments.
The Red Team worked with the growth of prostate cancer cells in the Bioreactor Demonstration System, shutdown of the Laminar Soot Processes experiment, which completed 14 runs in an effort to better understand the nature of soot created by combustion in microgravity, and bacteria and yeast growth as part of the Microbial Physiology Flight Experiment. They also checked on the growth of plants in the Astroculture experiment that includes miniature roses being grown in space to produce new fragrances for perfumes.
The Red Team handed over to the Blue Team -- Pilot Willie McCool, Payload Commander Michael Anderson and Mission Specialist Dave Brown -- at 6 p.m. EST, and prepared for a sleep shift beginning at 8:09 p.m. The Blue Team awoke at 4:09 p.m. to the song "Hakuna Matata" by the Baja Men for Anderson from his two kids.
The Blue Team began its day with work on the SOFBALL, or Structures of Flame Balls at Low Lewis-number experiment, which scientists hope will improve their understanding of lean (low fuel) burning combustion and lead to improvements in engine efficiency, reduced emissions, and fire safety.
The overnight team also worked with the Advanced Respiratory Monitoring System, a European Space Agency experiment looking at how the human body adapts to weightlessness.
After lunch, the team was to calibrate the Mediterranean Israeli Dust Experiment (MEIDEX) and resume observations after adjusting the shuttle orientation in orbit to facilitate measurement of small particles in the atmosphere over the Mediterranean Sea and Atlantic Ocean off the coast of the Sahara desert.
Cooling and humidity control of the Spacehab module is being effectively managed through minor adjustments to systems aboard Columbia and the science module.
TUESDAY, JANUARY 21, 2003
The Blue Team was awakened at 3:39 p.m. CDT to the sounds of "The Wedding Song" by Paul Stookey, uplinked from Mission Control especially for Pilot Willie McCool. McCool and Blue Team Astronauts Dave Brown and Michael Anderson will begin work after a handover at 6:24 p.m. EST The Red Team of Rick Husband, Kalpana Chawla, Laurel Clark and Ilan Ramon begins its sleep shift at 8:39 p.m.
Israel Space Agency Payload Specialist Ilan Ramon took a break from observations of thunderstorms today to speak with Israeli Prime Minister Ariel Sharon and other dignitaries in Jerusalem. Ramon captured never-before-photographed lightning phenomena, known as "sprites" and "elves," in the extreme upper atmosphere using Middle Eastern Dust Experiment (MEIDEX) cameras. The experiment's primary objective is to study dust storms in the Middle East, but clouds in the region have delayed those observations thus far.
Work continued with a study of combustion in space, focusing on understanding the nature of soot. The Laminar Soot Processes experiment was operated by Ramon to burn various fuels in weightlessness and study production of soot. Weightlessness alllows the process to be studied without the interference caused by gravity-induced convection.
Other experiments run today included continued growth of prostate cancer cells in the Bioreactor Demonstration System (BDS), a device that has been shown on previous flights to grow cultures of much greater fidelity than can be produced in ground labs. The space-grown cultures may help scientists unlock lethal secrets of prostate cancer that allow it to spread through the bones and other body tissues. Mission Specialist Laurel Clark, a medical doctor, worked with the culture device today, checking its operation and photographing the tissues that have grown.
For other experiments, Commander Rick Husband steered Columbia to aim payload-bay mounted instruments to study ozone in the upper atmosphere and another experiment that studies the solar constant. The Shuttle Ozone Limb Sounding Experiment-2 (SOLSE-2) uses observations of sunlight scattering by the atmosphere to measure ozone. The Solar Constant Experiment (SOLCON) measures solar irradiance above the atmosphere.
The Blue Team will continue observations of "sprites" with the MEIDEX cameras, studies of soot with the Laminar Soot Process apparatus and examinations of bone cell activity in microgravity using the Osteoporosis Experiment in Orbit. The second half of its day will include off-duty time to help stay fresh for the extended-duration mission.
Cooling and humidity control of the Spacehab module is being managed through minor adjustments to systems aboard Columbia and the science module. The Spacehab's dehumidifiers remain off due to problems experienced in the last few days. The cooling glitch is not expected to interrupt any of the mission's ongoing research. Flight controllers are continuing to investigate options for reactivating the dehumidifiers.
MONDAY, JANUARY 20, 2003
Red team members Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark and Israeli Payload Specialist Ilan Ramon conducted additional data takes with the Mechanics of Granular Materials experiment located in the Spacehab Research Module in Columbia's cargo bay. The MGM experiment is providing information on the behavior of saturated sand when exposed to confining pressures in microgravity. The experiment could provide engineers valuable data for strengthening buildings against earthquakes.
The Red team is working what amounts to the day shift on orbit, while the Blue team -- Pilot Willie McCool, Mission Specialist Dave Brown and Payload Commander Mike Anderson -- is working the overnight shift. The division of the two teams into 12-hour shifts assures that scientific research is conducted round-the-clock.
One of the host of experiments in the Spacehab science lab -- the Microbial Physiology Flight Experiment -- was monitored by Clark as she studied how specific fungi react to the absence of gravity for long periods of time.
Additional data was acquired by Anderson and Ramon with an experiment in the Combustion Module in the Spacehab -- the study of Laminer Soot Processes (LSP) -- designed to gain a better understanding of soot formation, oxidation and radiative properties within flames. Two other experiments studying flame properties in space in the large Spacehab furnace are to be conducted throughout the course of the flight.
Work was also accomplished with a series of biomedical experiments studying the human body's response to weightlessness -- particularly dealing with protein manufacturing in the absence of a gravity environment, bone and calcium production, the formation of chemicals associated with renal stones and how saliva and urine change in space relative to any exposure to viruses. The crewmembers also continued periodic blood draws to study how their bodies are adapting to the microgravity environment.
Experiments continued with the MEIDEX cameras in the cargo bay observing thunderstorms to capture images of sprites, which are associated with discharges from the tops of thunderclouds into the Earth's upper atmosphere, and with the SOLSE experiment, studying the amount of ozone in the Earth's upper atmosphere by using a special imaging spectrometer in the payload bay to look across the limb of the Earth during specifically scheduled orbits.
Having been awakened just after 5 p.m. EST, McCool, Brown and Anderson planned to continue the more than 80 experiments on board Columbia. The Red team will begin its eight-hour sleep period just after 9 p.m. EST.
This afternoon, flight controllers observed a minor electrical current spike in one of two systems designed to collect and distribute water produced from condensation buildup caused by the operation of the cooling system in the Spacehab Research Module in the cargo bay.
An identical system sprung a leak under the floorboards of Spacehab last night and was shut down. The secondary system had been operating normally until the electrical spike was observed at around 2:15 p.m. A plan was implemented to reconfigure a valve in Columbia, allowing cool air from the shuttle to flow into the science module, thus enabling the module's temperatures to remain at a level that will not require the use of Spacehab's cooling system, while preventing any further buildup of condensation. Later, an air duct was routed from Columbia to the Spacehab to increase the flow of cool air into the science facility.
Flight controllers plan to continue their analysis of the Spacehab cooling issue throughout the night, with no impact expected to science operations.
Aboard the International Space Station, Expedition 6 Commander Ken Bowersox, Flight Engineer Nikolai Budarin and ISS Science Officer Don Pettit entered their third month in orbit today with a full complement of scientific research activities, exercise and routine ISS maintenance work.
The three ISS crewmembers conducted a number of cardiovascular tests, unloaded samples from a Zeolite Crystal Growth experiment in the Destiny laboratory that has completed its work for this Expedition. The Russian Vozdukh carbon dioxide removal system in the Zvezda Module, which shut down last week, is now operating normally following the weekend replacement of a valve. The U.S. segment CO2 removal system, which has been operating in place of Vozdukh, was powered down as a result of the Vozdukh revival.
All other station systems are operating normally as are all the systems aboard the shuttle Columbia, which, like the ISS, is orbiting the Earth every 90 minutes.
SUNDAY, JANUARY 19, 2003
Red Team members Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark and Israeli Payload Specialist Ilan Ramon completed the first data collection sessions with the Combustion Module in the Spacehab research module housed in Columbia's cargo bay. One of three experiments housed in the Combustion Module -- the study of Laminer Soot Processes (LSP) -- is designed to gain a better understanding of soot formation, oxidation and radiative properties within flames.
Additional data was gleaned from the Mechanics of Granular Materials experiment (MGM) in the Spacehab module, which is providing information on the behavior of saturated sand when exposed to confining pressures in microgravity. The experiment could provide engineers with valuable data for strengthening buildings against earthquakes.
Work was also accomplished with a series of biomedical experiments studying the human body's response to weightlessness -- particularly dealing with protein manufacturing in the absence of a gravity environment, bone and calcium production, the formation of chemicals associated with renal stones and how saliva and urine change in space relative to any exposure to viruses.
Experiments continued with the MEIDEX cameras in the cargo bay observing dust storms in the Mediterranean region and with the SOLSE experiment, geared to studying the amount of ozone in the Earth's atmosphere by using a special imaging spectrometer in the payload bay to look across the limb of the Earth during specifically scheduled orbits.
Columbia's Blue Team science cadre -- Pilot Willie McCool and Mission Specialists Dave Brown and Mike Anderson -- planned to continue the more than 80 experiments on board Columbia following their wakeup call this afternoon. The Red team will begin its eight-hour sleep period just before 10 p.m. EST.
Earlier today, TV cameras in the Spacehab research module captured Ramon conducting work with the Combustion Module. He reported that the materials science facility was operating perfectly as are all of the other experiment facilities aboard Columbia.
Aboard the International Space Station, Commander Ken Bowersox, Flight Engineer Nikolai Budarin and ISS Science Officer Don Pettit completed their second month in space by enjoying an off-duty day. The crew will return to a full complement of scientific research activities, exercise and routine ISS maintenance work on Monday. The ISS crew is working a schedule, which calls for them to be awakened every morning at 1:00 a.m. EST and for their 8 1é2 hour sleep period to begin at 4:30 p.m. EST.
The ISS crew was informed that replacement parts for the Microgravity Science Glovebox will be ready for launch on the next Progress resupply vehicle to the ISS on February 2. With docking of that cargo ship to the ISS planned for Feb. 4, virtually all of the science planned for the facility during Expedition 6 will be accomplished as initially planned.
All systems aboard Columbia and the ISS continue to function well.

THURSDAY, JANUARY 16, 2003
Columbia lifted off at 10:39 a.m. EST from the Kennedy Space Center in near-perfect weather after a flawless countdown. The crew opened the spacecraft's payload bay doors about 12:35 p.m. and then were given the go-ahead for on-orbit operations.
The seven-member crew is divided into two teams, each working 12 hours per day during most of the flight. Members of the blue team, Pilot Willie McCool and Mission Specialists Dave Brown and Mike Anderson, began a six-hour sleep period at 3:47 p.m. EST and will be awakened at 9:49 p.m. Red team members, Commander Rick Husband, Mission Specialists Kalpana Chawla and Laurel Clark, and Israeli Payload Specialist Ilan Ramon, begin a 7-hour sleep period at 10:39 p.m.
Spacehab is a pressurized research module 20 feet long, 14 feet wide and 11 feet high. It houses equipment for 59 experiments, three of them mounted on its roof. Its activation marks the beginning of the major science activities of Columbia's mission.
All systems aboard Columbia continue to function flawlessly.
The shuttle is at an altitude of about 178 statute miles, in an orbit inclined 39 degrees to the equator.
Aboard the International Space Station, Expedition 6 crewmembers, Commander Ken Bowersox, Flight Engineer Nikolai Budarin and NASA ISS Science Officer Don Pettit, received a live video uplink of the launch through the ISS Flight Control Room in the Mission Control Center at Johnson Space Center in Houston.

Following tanking procedures, a team called the Final Inspection Team was dispatched to the pad to check the vehicle one last time prior to liftoff. The six-person team, comprised of five engineers and one safety official, is currently performing the inspections at pad 39A. At the conclusion of their two-hour tour-of-duty, they will have walked up and down the entire 380-foot fixed service structure and mobile launcher platform.
The team is on the lookout for any abnormal ice or frost build-up on the vehicle that could break-off during ignition and damage the spacecraft. The team is also searching for any loose debris that could possibly fly up and strike the vehicle at launch. And the third item of interest to the team is the thermal integrity of the external tank foam insulation.
The team uses a portable infrared scanner that gathers temperature measurements on the surface area of the shuttle and can spot leaks. The scanner will be used to obtain temperature data on the external tank, solid rocket boosters, space shuttle orbiter, main engines and launch pad structures. The scanner can also spot leaks of the cryogenic propellants, and due to its ability to detect distinct temperature differences, can spot any dangerous hydrogen fuel that is burning. One team member is also responsible for photo documentation.
Each member of the Final Inspection Team is in constant contact with the NASA Test Director in the Firing Room.
The team wears the highly visible day-glow orange coveralls that are anti-static and flame resistant. Each member also has a self-contained emergency breathing unit that holds about 10 minutes of air.
Following the Final Inspection Team's activities, they will meet with NASA Launch Director Mike Leinbach, the Mission Management Team, and engineering directors in the launch control center, providing a detailed report on the inspections and findings at the pad 39A.
A full inspection of the vehicle and pad was performed yesterday and the external tank received a thorough check prior to fueling last night.
An inspection of the launch pad and beach will be made following launch. That inspection will be to look for anything unusual, particularly anything that could have fallen off of the vehicle during the first few seconds of flight. Later, there will be a meeting to review high-speed videotape and film of the launch and early ascent to determine if there was any damage to the vehicle.
1052 GMT (5:52 a.m. EST)
But given the cryogenic nature of the oxidizer and propellant, the supplies naturally boil away. So the tanks are continuously topped off until the final minutes of the countdown in a procedure called "stable replenishment."
With the hazardous tanking operation completed, the Orbiter Closeout Crew and Final Inspection Team are being dispatched to the pad to perform their jobs. The closeout crew will ready Columbia's cockpit for the astronauts' boarding in a couple of hours; and the inspection team will give the entire vehicle a check for any ice formation from fueling.
NASA officials say all systems remain "go" for an on-time liftoff at 10:39 a.m. EST today.

The three-hour process to load the shuttle's orange external fuel tank began at 3:06 a.m. EST.
There are actually two tanks inside the orange tank. The liquid oxygen tank fills the top third of the external tank. It will be filled with 143,000 gallons of liquid oxygen chilled to minus 298 degrees Fahrenheit (minus 183 degrees Celsius). The liquid hydrogen tank is contained in the bottom two-thirds of the external tank. It holds 385,000 gallons of liquid hydrogen chilled to minus 423 degrees Fahrenheit (minus 253 degrees Celsius).
The cryogenics are pumped from storage spheres at the pad, through feed lines to the mobile launcher platform, into Columbia's aft compartment and finally into the external tank.
The fueling process is being orchestrated by engineers in the safe confines of the Kennedy Space Center's Launch Control Center located about 3 1/2 miles from launch pad 39A.
