Thermal insulation is the reduction of heat transfer between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
STS-107 was the 113th flight of the Space Shuttle program, and the 28th and final flight of Space Shuttle Columbia. The mission ended on February 1, 2003, with the Space Shuttle Columbia disaster which killed all seven crew members and destroyed the space shuttle. It was the 88th post-Challenger disaster mission.
Kalpana Chawla was an Indian-born American astronaut and aerospace engineer who was the first woman of Indian origin to fly to space. She first flew on Space Shuttle Columbia in 1997 as a mission specialist and primary robotic arm operator aboard STS-87.
On Saturday, February 1, 2003, Space Shuttle Columbia disintegrated as it reentered the atmosphere over Texas and Louisiana, killing all seven astronauts on board. It was the second Space Shuttle mission to end in disaster, after the loss of Challenger and crew in 1986.
In engineering, a heat shield is a component designed to protect an object or a human operator from being burnt or overheated by dissipating, reflecting, and/or absorbing heat. The term is most often used in reference to exhaust heat management and to systems for dissipating frictional heat. Heat shields are used most commonly in automotive and aerospace.
Robert Brent "Bob" Thirsk, is a Canadian retired engineer and physician, and a former Canadian Space Agency astronaut. He holds the Canadian record for the most time spent in space. He became an officer of the Order of Canada (OC) in 2013 and was named to the Order of British Columbia (OBC) in 2012.
NASA's Long Duration Exposure Facility, or LDEF, was a cylindrical facility designed to provide long-term experimental data on the outer space environment and its effects on space systems, materials, operations and selected spores' survival. It was placed in low Earth orbit by Space ShuttleChallenger in April 1984. The original plan called for the LDEF to be retrieved in March 1985, but after a series of delays it was eventually returned to Earth by Columbia in January 1990.
Bonnie Jeanne Dunbar is an American engineer and retired NASA astronaut. She flew on five Space Shuttle missions between 1985 and 1998, including two dockings with the Mir space station.
Kapton is a polyimide film used in flexible printed circuits and space blankets, which are used on spacecraft, satellites, and various space instruments. Invented by the DuPont Corporation in the 1960s, Kapton remains stable across a wide range of temperatures, from 4 to 673 K. Kapton is used in electronics manufacturing, space applications, with x-ray equipment, and in 3D printing applications. Its favorable thermal properties and outgassing characteristics result in its regular use in cryogenic applications and in situations where high vacuum environments are experienced.
Memory foam consists mainly of polyurethane with additional chemicals that increase its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu). The foam bubbles or ‘cells’ are open, effectively creating a matrix through which air can move. Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover their original shape more quickly.
In materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers in solution into a colloidal solution (sol) that acts as the precursor for an integrated network of either discrete particles or network polymers. Typical precursors are metal alkoxides. Sol–gel process is used to produce ceramic nanoparticles.
The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the searing 1,650 °C (3,000 °F) heat of atmospheric reentry. A secondary goal was to protect from the heat and cold of space while in orbit.

Nicole Marie Passonno Stott is an American engineer and a retired NASA astronaut. She served as a flight engineer on ISS Expedition 20 and Expedition 21 and was a mission specialist on STS-128 and STS-133. After 27 years of working at NASA, the space agency announced her retirement effective June 1, 2015. She is married to Christopher Stott, a Manx-born American space entrepreneur.
LI-900 is a type of reusable surface insulation tile developed and manufactured by Lockheed Missiles and Space Company in Sunnyvale, California. It was designed for use on the Space Shuttle orbiter as part of its thermal protection system to minimize thermal conductivity while providing maximum thermal shock resistance.
Jeanette Jo Epps is an American aerospace engineer and NASA astronaut. Epps received both her M. S. and Ph.D. degrees in aerospace engineering from the University of Maryland, where she was part of the rotor-craft research group and was a NASA GSRP Fellow. She was chosen for the 20th class of NASA astronauts in 2009, graduating in 2011. Epps currently serves as a member of the ISS Operations Branch and has completed analog astronaut missions, including NEEMO 18 and CAVES 19. She is the second woman and first African-American woman to have participated in CAVES. She is currently in space for a long duration mission on the ISS, after launch in 4 March 2024, as part of the SpaceX Crew-8 crew.
Tracy Caldwell Dyson is an American chemist and NASA astronaut. She was a mission specialist on Space Shuttle Endeavour flight STS-118 in August 2007 and part of the Expedition 23 and Expedition 24 crew on the International Space Station from April 2010 to September 2010. She has completed three spacewalks, logging more than 22 hours of extravehicular activity. She is currently in space since March 23, 2024 for a third time, for a six-month mission onboard the ISS.
The Stöber process is a chemical process used to prepare silica particles of controllable and uniform size for applications in materials science. It was pioneering when it was reported by Werner Stöber and his team in 1968, and remains today the most widely used wet chemistry synthetic approach to silica nanoparticles. It is an example of a sol-gel process wherein a molecular precursor is first reacted with water in an alcoholic solution, the resulting molecules then joining together to build larger structures. The reaction produces silica particles with diameters ranging from 50 to 2000 nm, depending on conditions. The process has been actively researched since its discovery, including efforts to understand its kinetics and mechanism – a particle aggregation model was found to be a better fit for the experimental data than the initially hypothesized LaMer model. The newly acquired understanding has enabled researchers to exert a high degree of control over particle size and distribution and to fine-tune the physical properties of the resulting material in order to suit intended applications.
Aerogels are a class of synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas, without significant collapse of the gel structure. The result is a solid with extremely low density and extremely low thermal conductivity. Aerogels can be made from a variety of chemical compounds. Silica aerogels feel like fragile styrofoam to the touch, while some polymer-based aerogels feel like rigid foams.
