Work on launch vehicle delays next Mars rover
Officials have delayed the launch of NASA's Mars Exploration Rover "Opportunity" so workers can replace insulation of the Boeing Delta 2 rocket that will propel the spacecraft to the Red Planet.
Trio peeks at secret recipe for stormy solar weather
A three-spacecraft collaboration recorded for the first time the entire initiation process of a high-speed eruption of electrified gas from the Sun, providing clues about the Sun's secret recipe for stormy weather.
Universe slightly simpler than expected
The universe just became a little less mysterious. Using images from the Hubble Space Telescope, astronomers at the University of Florida have concluded that two of the most common types of galaxies in the universe are in reality different versions of the same thing.

Space shuttle tile repair options in development
Shuttle engineers believe the tools and techniques needed for spacewalking repair crews to access and patch areas of potentially catastrophic damage to an orbiter's heat-shield tiles should be in place by the end of the year, sources say, assuming upcoming tests go well.
Mars-bound Spirit rover adjusts trajectory
NASA's Spirit spacecraft, the first of twin Mars Exploration Rovers, performed its first trajectory correction maneuver Friday. The craft first performed a calibration and check of its eight thrusters, then fired the thrusters to fine-tune its flight path toward Mars.

The secret lives of galaxies unveiled in deep survey
Two of NASA's Great Observatories, bolstered by the largest ground-based telescopes around the world, are beginning to harvest new clues to the origin and evolution of galaxies. It's a bit like finding a family scrapbook containing snapshots that capture the lives of family members from infancy through adolescence to adulthood.
Stardust tweaks course for comet rendezvous
198 days before its historic rendezvous with a comet, NASA's Stardust spacecraft successfully completed the mission's third deep space maneuver. This critical maneuver modified the spacecraft's trajectory, placing it on a path to encounter and collect dust samples from comet Wild 2 in January 2004.
Molniya satellite deployed from Plesetsk spaceport
Russian space forces successfully launched a military communications satellite into orbit from its northern cosmodrome Thursday, wire reports said.
Lu talks of 'silver lining' from the Columbia tragedy
Space station science officer Ed Lu sees a potential "silver lining" in the aftermath of the Columbia disaster, saying today the loss of the shuttle may prompt renewed debate about development of more modern follow-on vehicles.

Space shuttle flights could restart in December
NASA expects to announce its shuttle return to flight plans soon after the Columbia Accident Investigation Board reports this summer and could realistically resume missions as early as December, a senior space agency official said Wednesday.
Engineers assess bi-pod redesign options
NASA is considering five options for redesigning the so-called "bi-pod" ramp system on the shuttle's external fuel tank, the area where a chunk of foam insulation broke away during Columbia's launch, hit the left wing and possibly caused a catastrophic breach. The currently favored option calls for eliminating the use of foam in the area in favor of an exposed fitting equipped with heaters to prevent pre-launch ice buildups.
Two key modules for space station arrive in Florida
Despite the on-going grounding of space shuttle flights, work continues at Kennedy Space Center to ready massive pieces of the international space station for launches to finish assembling the orbiting complex.

Have a question for station crew? Here's your chance!
Spaceflight Now will be conducting an exclusive live interview with the Expedition 7 crew living aboard the international space station on Tuesday, June 24. As part of this event, we are giving readers the opportunity to submit questions for commander Yuri Malenchenko and science officer Ed Lu. Please include your name and location in the email with the question.
Space station transport ship gets go-ahead
In early June, the European Space Agency's Automated Transfer Vehicle program reached a milestone in successfully passing the Critical Design Review during which some 140 international space experts expressed their full confidence in the design of the vehicle after analysing 55,000 pages of technical documentation. The ATV will deliver supplies to the space station.
Scientists image 3-D surface of the sun
Solar physicists have analyzed the highest resolution images ever taken near the solar limb, and found a surprising variety of structure. Their results address long-standing theories on how the brightness of the Sun varies over the course of its magnetic cycle. Such changes may influence the Earth's climate on long timescales.

New launch date set for 'Opportunity' rover
Launch of NASA's Mars Exploration Rover Opportunity has been put off one day -- to June 26 -- to give workers more time to complete pre-flight preparations, the space agency said Monday.
Delta 2
'Solar tsunamis' used to study the solar corona
Since the launch of the Solar and Heliospheric Observatory in 1995, scientists have used it to study flares, filaments and coronal mass ejections. The telescope has also discovered solar tsunamis, huge propagating waves that are triggered along with coronal mass ejections and can travel the entire diameter of the sun. Researchers are applying this unusual phenomenon for the first time to new studies of the solar corona.

Evidence for meteor in early mass extinction found
It's the stuff of science fiction movies. Bruce Willis, by a mighty effort, saving the world from extinction by a huge meteor. But Bruce Willis won't do it, and in our current state of readiness, neither will anyone else.
Veteran astronaut begins new adventure in education
James Voss, one of NASA's most experienced astronauts having logged five shuttle flights and served as a member of the space station's Expedition 2 crew, has left the agency for a position at Auburn University.
