Solar grand slam
While Tiger Woods was trying to claim the top four golf tournaments, the Sun delivered a grand slam of its own, blasting four of its most powerful class of solar flares in just eight days. Solar flares are tremendous explosions in the atmosphere of the Sun, with the most powerful class, called the X class, capable of releasing as much energy as a billion megatons of TNT.
Ariane 5 rocket to launch French Helios 2A craft
An Ariane 5 will launch the Helios 2A satellite into a sun-synchronous polar orbit during the second half of 2004 from the Guiana Space Center, Europe's Spaceport in Kourou, French Guiana.
Teachers take NASA mission
The nation's top teachers -- chosen by their peers -- will journey on a week-long space "mission" this summer, courtesy of NASA. National Teacher of the Year Chauncey Veatch of Palm Desert, Calif., and the other honorees will be recognized for their dedication to their profession during the annual International Space Camp event.

Atlas 5 launch delayed from Aug. 12 by satellite issue
Launch of the first Atlas 5 rocket is being postponed after technicians ran into delays readying the mission's commercial satellite cargo for flight. A new launch date has not been set, but officials remain optimistic liftoff will occur sometime in August.

Backup crew member assigned to Expedition Six
Donald Pettit, Ph.D., a member of the Expedition Six backup crew, will replace Donald Thomas, Ph.D., on the future mission to the International Space Station.
Columbia expected to leapfrog station flights
Confident shuttle fuel line cracks can be fixed, if necessary, by welding, NASA managers are converging on a plan to resume shuttle launches in late September or early October with the first of two back-to-back space station assembly missions. Under that preferred scenario, launch of the shuttle Columbia, originally scheduled for July 19, would slip to around Dec. 3.

Wiring review delays Delta 2 launch for Air Force
The next launch of a replacement Global Positioning System military satellite aboard a Boeing Delta 2 rocket, once envisioned to occur in mid-August, has been postponed while engineers study wiring harnesses in the Delta fleet.

Senate committee approves funding for Pluto mission
The Senate Appropriations Committee approved a 2003 budget for NASA on Thursday that includes funding for a controversial mission to Pluto. The full committee passed the budget two days after a subcommittee approved the proposal. The budget would give NASA $15.2 billion in fiscal year 2003.

Space waves caused by black hole mergers modeled
Merging black holes will rock the fabric of space and time with gravitational waves that start quiet, grow to a thunderous roar at the moment of impact, and then resonate from the final gong, according to international team of scientists who have created a novel computer model of such a merger based on Einstein's equations.
Hazy camera on Saturn-bound Cassini clears up
Now within two years of reaching Saturn, NASA's Cassini spacecraft took test images of a star last week that reveal successful results from an extended warming treatment to remove haze that collected on a camera lens last year.
New center director named for NASA's Stennis
Roy S. Estess, center director for NASA's John C. Stennis Space Center in Mississippi, has announced plans to retire after 42 years in government service, 37 with NASA. Administrator Sean O'Keefe named William (Bill) W. Parsons Jr., the current Center Operations and Support Director at Stennis, as Estess' successor, effective August 25th.

Dwarf galaxies give a breath of fresh oxygen
Astronomers have discovered that a nearby dwarf galaxy is spewing oxygen and other "heavy" elements into intergalactic space. This observation from NASA's Chandra X-ray Observatory supports the idea that dwarf galaxies might be responsible for most of the heavy elements between the galaxies.
Lockheed instrument to fly on ESA comet probe
An instrument called ROSINA, with key components designed and built at the Lockheed Martin, will be launched early next year on the European Space Agency's Rosetta spacecraft. The goal of the ambitious international mission is to catch up with, orbit, and land on Comet Wirtanen in an effort to answer questions about the origin of our Solar System.

Pluto mission faces key funding test
A proposed mission to Pluto, recently endorsed by an independent scientific panel, will undergo a key test this week in its effort to obtain funding for the project. The New Horizons mission requires $122 million in the fiscal year 2003 budget in order to continue work and meet a 2006 launch deadline.
NASA developing hypersonic technologies
Imagine taking off from any U.S. airport and landing on any other runway in the world in less than two hours. Or making a quick hop from that same airport to the International Space Station and back - a trip that normally takes days or weeks - to drop off science experiments, provisions and new equipment.
Weather on brown dwarfs
Until recently, "How's the weather up there?" was a question for pilots, NBA stars and friendly giants. Today, however, you might also ask a dwarf. A brown dwarf, that is. Brown dwarfs, which have been described as "failed stars," are celestial bodies more massive than planets like Jupiter but not large enough to sustain the thermonuclear reactions that make a star shine.

Atom research may help detect volcanoes, oceans
Breakthrough research on waves of ultra-cold atoms may lead to sophisticated atom lasers that might eventually predict volcanic eruptions on Earth and map a probable subsurface ocean on Jupiter's moon Europa.
