STS-107 in the context of Ilan Ramon

On Saturday, February 1, 2003, Space Shuttle Columbia disintegrated as it re-entered the atmosphere over Texas and Louisiana, killing all seven astronauts on board. It was the second of two Space Shuttle missions to end in disaster, after the loss of Challenger and crew in 1986.

The mission, designated STS-107, was the twenty-eighth flight for the orbiter, the 113th flight of the Space Shuttle fleet and the 88th after the Challenger disaster. It was dedicated to research in various fields, mainly on board the SpaceHab module inside the shuttle's payload bay. During launch, a piece of the insulating foam broke off from the Space Shuttle external tank and struck the thermal protection system tiles on the orbiter's left wing. Similar foam shedding had occurred during previous Space Shuttle launches, causing damage that ranged from minor to near-catastrophic, but some engineers suspected that the damage to Columbia was more serious. Before reentry, NASA managers limited the investigation, reasoning that the crew could not have fixed the problem if it had been confirmed. When Columbia reentered the atmosphere of Earth, the damage allowed hot atmospheric gases to penetrate the heat shield and destroy the internal wing structure, which caused the orbiter to become unstable and break apart.

STS-118 was a Space Shuttle mission to the International Space Station (ISS) flown by the orbiter Endeavour. STS-118 lifted off on August 8, 2007, from launch pad 39A at Kennedy Space Center (KSC), Florida and landed at the Shuttle Landing Facility at KSC on August 21, 2007.

This was the first flight of Endeavour since STS-113 in November 2002, which was also the last successful shuttle flight before STS-107 which culminated in the loss of Columbia when it disintegrated during reentry. STS-118 pilot Charles Hobaugh had been the entry team CAPCOM for STS-107. Columbia had originally been selected for this flight, for what would have been its 29th mission, and its first and likely only visit to the ISS, mainly due to its heavier weight.

STS-109 (Hubble Servicing Mission 3B 'SM3B') was a Space Shuttle mission that launched from the Kennedy Space Center on 1 March 2002. It was the 108th mission of the Space Shuttle program, the 27th flight of the orbiter Columbia and the fourth servicing of the Hubble Space Telescope. It was also the last successful mission of the orbiter Columbia before the ill-fated STS-107 mission, which culminated in the Columbia disaster.

The Hubble Space Telescope (HST) was placed in orbit during mission STS-31 on 25 April 1990. Initially designed to operate for 15 years, plans for periodic service and refurbishment were incorporated into its mission from the start. After the successful completion of the second planned service mission (SM2) by the crew of STS-82 in February 1997, three of the telescope's six gyroscopes failed. NASA decided to split the third planned service mission into two parts, SM3A and SM3B. A fifth and final servicing mission, STS-125 (SM4) launched on 11 May 2009. The work performed during SM4 kept HST in operation through 2024.

The Research Double Module (RDM) was a payload module built by Spacehab Inc (now Astrotech Corporation) for the US Space Shuttle Orbiters. The module flew only on the ill-fated Space Shuttle Columbia STS-107 mission, in which it was destroyed.

Kalpana Chawla (March 17, 1962 – February 1, 2003) was an Indian-American astronaut and aerospace engineer who was the first woman of Indian origin to fly to space. Chawla expressed an interest in aerospace engineering from an early age and took engineering classes at Dayal Singh College and Punjab Engineering College in India. She then traveled to the United States, where she earned her MSc and PhD, becoming a naturalized United States citizen in the early 1990s.

She first flew on the Space Shuttle Columbia in 1997 as a mission specialist and robotic arm operator aboard STS-87. Her role in the flight caused some controversy due to the failed deployment of the Shuttle-Pointed Autonomous Research Tool for Astronomy ("Spartan") module. Chawla's second flight was in 2003 on STS-107, the final flight of Columbia. She was one of the seven crew members who died in the Space Shuttle Columbia disaster when the spacecraft disintegrated during its reentry into Earth's atmosphere on February 1, 2003.
