The space shuttle Columbia glowed brightly as it streaked across the predawn skies of the western United States on Feb 1, 2003. Decelerating from an orbital speed of 28,165 km/hr (17,500 miles/hr) at an altitude of 70,165 m (230,200 ft), the shuttle and its seven crew members were enveloped in super heated plasma as they descended deeper into the thickening atmosphere on their return from a 16-day science mission.
Three observers on the ground who were filming the fiery reentry suddenly noticed something odd. There was a sudden flash on the orbiter, and then bright objects streaked behind the ship and burned up.
“Look at the chunks coming off that,” one shouted. “What the heck is that?”
Astrogenetix PR — NASA astronauts onboard Space Shuttle Discovery’s final mission to the International Space Station (ISS) will carry out the eleventh scientific payload for Astrogenetix, a commercial biotech company based out of Austin, Texas. The research on STS-133 will focus on changes that occur to methicillin-resistant Staphylococcus aureus (MRSA) in microgravity, which can be targeted to create new vaccines and therapeutics.
NASA PR — Space shuttle Discovery docked to the International Space Station at 2:14 p.m. EST Saturday with its cargo of a new station module, equipment and supplies for the orbiting laboratory. (more…)
We’ve got a busy couple of weeks ahead in terms of American launches. The schedule:
Glory Date: Wednesday, Feb. 23 Time: 5:09 a.m. EST Location: Vandenberg Air Force Base, Calif. Coverage:http://www.nasa.gov/ntv (3:30 a.m. EST start)
NASA’s Glory mission will allow scientists to better understand how the sun and tiny atmospheric particles called aerosols affect Earth’s climate. Both aerosols and solar energy influence the planet’s energy budget â€“ the amount of energy entering and exiting Earth’s atmosphere. An accurate measurement of these impacts is important to anticipate future changes to our climate.
NASA TV coverage will begin at 3:30 a.m. EST (12:30 a.m. PST) at http://www.nasa.gov/ntv. Liftoff is targeted for 5:09:43 a.m. EST (2:09:43 a.m. PST). Spacecraft separation from the Taurus XL rocket occurs 13 minutes after launch.
Space Shuttle Discovery Date: Thursday, Feb. 24 Time: 4:50 p.m. EST Location: Cape Canaveral, Fla. Coverage:http://www.nasa.gov/ntv
The much-delayed Discovery mission will finally get off the ground. The six-member crew will deliver and equipment and supplies to the International Space Station, including a Robonaut. This is the next-to-last mission or next-to-next-to-last mission for the 30-year old space shuttle program.
X-37B Date: Friday, March 4 Location: Cape Canaveral, Fla.
The U.S. Air Force’s mysterious space plane will lift off its second classified mission aboard an Atlas 5 rocket. The same vehicle completed a 225-day flight last year before touching down at Vandenberg Air Force Base.
Space shuttle Discovery remains in the Vehicle Assembly Building (VAB) as modifications and repairs are made to the external fuel tank’s support beams known as “stringers.” Additional support structures called radius blocks are being added to 95 stringers, meaning the entire circumference of the external tank will be strengthened by the time all the repairs and modifications are finished.
“It’s been a long road,” said John Shannon, Space Shuttle Program manager. “I’m very confident we have it finally figured out and we have a fix. We’re going to fly with a lot of confidence in this tank.”
Discovery will not launch on the STS-133 mission before Feb. 24, but shuttle managers have not yet chosen a target date for the mission. The schedule depends in part on traffic at the International Space Station during that time frame. A European cargo spacecraft, ATV-2, is scheduled to launch to the station Feb. 15 carrying supplies and equipment.
Space shuttle Discovery remains inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, where technicians today are starting repairs on three support beams, called stringers, on the outside of the shuttle’s external tank. Recent X-ray type image scans of all 108 of the tank’s stringers revealed four small cracks on three beams on the side opposite Discovery. Managers decided Thursday to have those cracks repaired in a similar fashion to repairs made on cracks found on two stringers after Discovery’s Nov. 5 launch attempt.
Also beginning today is another round of imaging — this time, using the backscatter method — on all of the tank’s stringers. Engineers at various NASA centers continue to analyze testing and imaging data.
The repair work is estimated to take 2-3 days. Any further work will be evaluated thoroughly during the week after additional data and analysis are reviewed.
Managers also continue to evaluate an option to perform known and practiced modifications on some stringers. Before breaking for the holiday, technicians reconfigured scaffolding to provide access for the modification work, should it be required. A decision may be made on that work as early as today.
The next available launch date for Discovery’s STS-133 mission to the International Space Station remains Feb. 3 at the opening of a window that extends through Feb. 10.
NASA managers have targeted space shuttle Discovery’s launch for no earlier than Feb. 3 at 1:34 a.m. EST. Shuttle managers determined more tests and analysis are needed before proceeding with the launch of the STS-133 mission to the International Space Station.
The Program Requirements Control Board met Thursday and reviewed engineering evaluations associated with cracks on two 21-foot-long, U-shaped aluminum brackets, called stringers, on the shuttle’s external tank. NASA repaired the cracks and reapplied foam to the exterior of the stringers.
NASA managers have targeted space shuttle Discovery’s launch for no earlier than Dec. 17. Shuttle managers determined more tests and analysis are needed before proceeding with the STS-133 mission. The launch status meeting planned for Monday, Nov. 29, has been postponed and will be rescheduled.
The Program Requirements Control Board reviewed on Wednesday repairs and engineering evaluations associated with cracks on two 21-foot-long, U-shaped aluminum brackets, called stringers, on the shuttle’s external tank. Managers decided the analysis and tests required to launch Discovery safely are not complete. The work will continue through next week.
The next status review by the PRCB will be Thursday, Dec. 2. If managers clear Discovery for launch on Dec. 17, the preferred time is about 8:51 p.m. EST.
At yesterdayâ€™s Program Requirements Control Board, or PRCB, the Space Shuttle Program clearly identified the analysis and repairs that are required to safely launch shuttle Discovery on its STS-133 mission. This analysis will be reviewed at a special PRCB on Wednesday, Nov. 24. Pending a successful review of the flight rationale at that meeting, a Launch Status Briefing would be held with senior NASA management on Monday, Nov. 29.
The Launch Status Briefing and news conference planned for Monday, Nov. 22 are cancelled. The Kennedy Space Center â€œCall-to-Stationsâ€ to begin the launch countdown will be no earlier than Nov. 30, supporting a first launch attempt no earlier than Dec. 3 at about 2:52 a.m. EST.
The STS-133 crew members are Commander Steven Lindsey, Pilot Eric Boe and Mission Specialists Alvin Drew, Michael Barratt, Tim Kopra and Nicole Stott.
Discovery will deliver and install the Permanent Multipurpose Module, the Express Logistics Carrier 4 and provide critical spare components to the International Space Station. This will be the 35th shuttle mission to the station.
Space shuttle Discovery and its seven-member crew landed at 8:53 p.m. EDT Friday at Edwards Air Force Base in California, capping off a 14-day mission to deliver supplies and research facilities to the International Space Station and its six-person crew.
Mission managers called off Friday afternoonâ€™s landing opportunities at Kennedy Space Center in Florida because of thunderstorms and otherwise unstable weather conditions.
Discoveryâ€™s arrival completes a two-week flight for Commander Rick Sturckow, Pilot Kevin Ford, and mission specialists Pat Forrester, Jose Hernandez, Danny Olivas and Christer Fuglesang. Friday was the 58th day in space for their crewmate Tim Kopra, who launched on shuttle mission STS-127 in July and spent two months on the International Space Station as an Expedition 20 crew member.
The STS-128 crew has been informed that Edwards Air Force Base will be activated for landing opportunities Friday. The weather at Kennedy Space Center Friday is forecast to be dynamic again. Weather at Edwards for Friday looks good.
The mission management team opted to give engineers more time to refine their analysis of a fill-and-drain valve inside Discovery rather than push quickly into a new launch cycle, NASA pre-launch mission management team chairman Mike Moses said.”We gave the team a day to go and keep working on it,” he said.
The decision moved Discovery’s liftoff to Friday at 11:59 p.m. EDT to begin the STS-128 mission to the International Space Station.
