Space Shuttle Columbia was the very first shuttle to reach area when it was launched from NASAs Kennedy Space Center on Apr. 12, 1981. Columbia carried dozens of astronauts into space during the next 20 years, reaching numerous turning points. The shuttle likewise went through upgrades as technology advanced.Space Shuttle Columbias final mission ended in catastrophe. The shuttle bus and seven-member crew were lost over Texas when Columbia burned up throughout re-entry on Feb 1, 2003. Columbias loss triggered NASA to do additional security checks in orbit for all future missions. Related: Columbia Disaster: What took place and what NASA found out Space shuttle bus: Decades of developmentDiscussions on developing a reusable spacecraft started in earnest in 1966, when NASA was aiming to find out what programs would follow Apollo. While NASA was charged with starting the work, advancement was held back for many years by monetary restraints, according to NASA history documents.Work resumed more seriously when the first landing on the moon impended, in 1969. At that time, then-President Richard Nixon appointed a Space Task Group to look at future area choices, and in subsequent years NASA began awarding design contracts for shuttle ideas.However, according to NASA history documents, when NASA submitted its September 1970 budget to the White House, it ended up being clear that the Nixon administration and Congress would not support the advancement of a space station and space shuttle bus at the same time. So NASA was required to reconsider its expectations and make some modifications to reduce expenses. Space Shuttle Columbia: Key truths– First flight: STS-1 (Apr. 12 -14, 1981)– Last flight: STS-107 (Jan. 16, 2003 – Feb. 1, 2003)– Number of missions: 28– Time in space: 300 days, 17 hours, 40 minutes, 22 seconds (Source: CBS) Some compromises were made in the style in response to monetary restraints and input from the military, which was anticipated to be a significant customer of the shuttle. The size of the cargo bay was increased to accommodate big military satellites. It was chosen to make the shuttle just partly reusable instead of fully recyclable to save on development expenses, although critics noted this would increase the costs of private flights according to NASA history documents.Construction started on a model on Jun. 4, 1974. That spacecraft was designated Enterprise. Its function was to perform test flights and landings, Space Shuttle Enterprise never flew into deep space. Construction on Space Shuttle Columbia started on Mar. 27, 1975. The Space Shuttle Columbia was named after the first American ship to circumnavigate the globe and likewise the command module for the Apollo 11 moon landing according to NASA. Space Shuttle Columbia flight milestonesCrowds gather on Rogers Dry Lake at Edwards Air Force Base to see the very first landing by Space Shuttle Columbia on Apr. 14, 1981. (Image credit: NASA) Space Shuttle Columbias first flight into area happened on Apr. 12, 1981, according to NASA. The shuttle bus program was officially referred to as the Space Transportation System (STS), so this flight was STS-1. The mission had a two-person team: the commander, John Young, a veteran of Gemini and Apollo, and the pilot, Bob Crippen. The goal was to make certain that Columbia worked well in space. Media attention, in specific, focused on the new system of 30,000 individual tiles covering the shuttle bus, which NASA had actually dealt with during the early days, according to NASA history documents. Columbia returned from its very first mission safely and several more test flights ran between 1981 and 1982. This included perhaps the most remarkable landing of the shuttle bus program, STS-3. An “autoland” system malfunctioned before landing on STS-3; the crew took over (as planned) right before landing, however the shuttle touched the runway faster than regular. After landing, Columbias nose pitched up suddenly due to a software problem, according to commander Jack Lousmas oral history with NASA.Space Shuttle Columbias first functional flight was STS-5, when it introduced on Nov. 11, 1982, and released two commercial communications satellites, according to NASA. The first operational flight for Columbia was STS-5 in November 1982. NASAs shuttle Challenger then handled the next 3 flights, and after that Columbia flew once again in November 1983 (STS-9), carrying the Spacelab experiment module for the very first time in addition to the first European Space Agency astronaut Ulf Merbold of Germany, according to NASA.Columbia was then shelved for major upgrades (including adding heads-up displays) prior to flying on just one objective in 1986; that objective brought Democrat Bill Nelson on board, amongst the astronauts. Shuttle bus operations were disrupted by the Space Shuttle Challenger catastrophe in January 1986. It wouldnt be up until 1989 that Columbia flew again.Related: In images: NASAs first space shuttle bus flight, STS-1 on Columbia Space Shuttle Columbia Science and telescope operationsColumbia flew 28 missions in its life time, logging more than 300 days in area. In its earliest days, it participated in repairing and releasing satellites and telescopes, however as NASAs concerns changed to science, Columbia flew several productive science objectives in the 1990s and 2000s. For many years it flew several microgravity lab missions and on Feb. 22, 1996, released on objective STS-75 with a connected satellite system experiment. The mission was created to bring the Tethered Satellite System Reflight (TSS-1R) into orbit and after that deploy it from a tether, according to ESA. Nevertheless, the tether broke prior to it had reached the preferred distance of 12.9 miles (20.7 km), according to ESA.In 1999 and 2002, though, Columbia shifted operations back into telescope operations. STS-93 was arranged to fly on Jul. 20, 1999, to send out the Chandra X-Ray Observatory into space.According to NASA, a suspected hydrogen problem scrubbed the initial launch just seven seconds before liftoff, however upon additional evaluation, NASA identified that the high readings were false.Columbia took off on the Chandra X-ray Observatory mission (STS-93) on Jul. 23, 1999, however its orbit was 7 miles shallower than prepared due to a somewhat early main engine cutoff, according to NASA. Adjustments in orbit were essential to bring Columbia to the correct altitude and the crew effectively deployed Chandra during the mission.Space Shuttle Columbias last effective mission was the Hubble Space Telescope Servicing mission– STS-109 when Columbia introduced on Mar. 1, 2002. Columbias objective consisted of five spacewalks to service the Hubble Space Telescope; where astronauts changed an aging power control unit, eliminated and installed solar arrays and performed science instrument upgrades. Maintenance time hit a record, at the time, of 35 hours and 55 minutes, breaking the previous record of 35 hours and 28 minutes set by Hubbles very first servicing mission STS-61, according to NASA. This would be Columbias next-to-last mission in orbit, although no one knew it at the time.The Columbia disasterNASA crew portrait of Space Shuttle Columbia STS-107 crew. Seated in the front, from left, are: Astronauts Rick D. Husband, objective commander; Kalpana Chawla, mission specialist; and William C. McCool, pilot. Standing, from left, are: David M. Brown, Laurel B. Clark, and Michael P. Anderson, all objective experts; and Ilan Ramon, payload expert, representing the Israeli Space Agency. (Image credit: NASA) Space Shuttle Columbias last flight was STS-107, an almost 16-day research objective concentrating on clinical experiments. The STS-107 team consisted of the very first Israeli astronaut, Ilan Ramon, and the very first Indian-born woman in area, Kalpana Chawla.On Feb. 1, 2003, NASA lost contact with Space Shuttle Columbia throughout the last minutes of its re-entry over Texas. Controllers invested a number of minutes trying to hail the shuttle bus as the families of the astronauts waited at the expected landing website at the Kennedy Space Center.As the interactions blackout lengthened, and video footage emerged of a big flying item breaking into pieces, it became clear that the crew had not survived.According to a team survival report launched by NASA in 2008, the team likely endured the initial separation however fell unconscious rapidly as the cabin depressurized. They passed away as the shuttle bus broke up around them. According to the crew survival report, their remains were retrieved from the ground and determined through DNA and oral records.Space Shuttle Columbias final crew Commander: Rick HusbandPilot: Willie McCoolPayload Commander: Michael AndersonMission Specialists: Kalpana Chawla, David Brown, Laurel Clark Payload Specialist: Ilan Ramon The Columbia Accident Investigation Board was formed to take a look at the reasons for the break up and to avoid it from happening again. Harold W. Gehman Jr., previous commander-in-chief of the U.S. Joint Forces Command, chaired the board. It consisted of involvement from a dozen people, including NASA officials and previous astronaut Sally Ride, who was also a member of Challengers investigation.The board concluded that a piece of foam from Columbias external tank struck the shuttle bus throughout launch and triggered a fatal breach in Columbias wing. This “foam debris” issue was widely known and documented in the years before Columbias launch, however with time NASA grew to accept it as part of spaceflight. The board recommended this issue be addressed.NASA made changes to the external tank along with put in new security treatments for shuttle objectives. Amongst them, on every spaceflight, the crew was required to spend a number of hours scanning the shuttles bottom for broken tiles. Forever rememberedNASA still remembers Space Shuttle Columbia, as well as past teams lost in the pursuit of spaceflight, on a yearly Day of Remembrance every January. Several memorials have been committed to the crew. 7 asteroids that orbit the sun in between Mars and Jupiter were named after the 7 crew members of STS-107. Visitors to the Kennedy Space Center can see particles from the Columbia objective (in addition to Challenger) at a display called “Forever Remembered,” which opened in 2015. The debris is on display at the visitors center and reveals window frames from Columbia, as well as individual artifacts from the astronauts. The households of the astronauts teamed up on producing the exhibit.Meanwhile, a few of the experiments from Columbias last flight returned useful information. This consisted of a set of roundworms (Caenorhabditis elegans) that endured re-entry and effectively reproduced. Some of the descendants flew in area aboard Space Shuttle Endeavour in May 2011.
