Workers attend a cryogenic insulation training session on Nov. 6, 2018, at the Cryogenics Laboratory at NASA's Kennedy Space Center in Florida. The training is for personnel who will be working to insulate pipes on the mobile launcher (ML). The ML is equipped with cryogenic fluid lines that will deliver hydrogen and oxygen to NASA's Space Launch System rocket. The lines must be kept well-insulated to maintain temperatures cold enough to keep fluids in a liquid state. In a new process, workers are learning how to pack spaces between pipes with aerogel granules in the same manner as they will on the ML.

Scientists at Marshall Space Flight Center (MSFC) have been studying the properties of Aerogel for several years. Aerogel, the lightest solid known to man, has displayed a high quality for insulation. Because of its smoky countenance, it has yet to be used as an insulation on windows, but has been used in the space program on the rover Sojourner, and has been used as insulation in the walls of houses and in automobile engine compartments. As heat is applied to Aerogel, scientist Dr. David Noever of Space Sciences Laboratory, Principal Investigator of Aerogel, studies for its properties trying to uncover the secret to making Aerogel a clear substance. Once found, Aerogel will be a major component in the future of glass insulation.

Scientists at MSFC have been studying the properties of Aerogel for several years. Aerogel, the lightest solid known to man, has displayed a high quality for insulation. Because of its smoky countenance it has yet to be used as an insulation on windows, but has been used to insulate the walls of houses and engine compartments in cars. It was also used in the space program as insulating material on the rover Sojourner, aboard the Mars Pathfinder. MSFC is one of the many research facilities conducting experiments to unlock the smoky properties of aerogel and make it a clear substance. MSFC researchers believe that by taking this research to space, they can resolve the problem of making aerogel transparent enough to see through. So far, recent space experiments have been encouraging. The samples produced in microgravity indicate a change in the microstructure of the material as compared to ground samples. MSFC scientists continue to study the effects of microgravity on Aerogel as their research is space continues.

Researcher examines a tubular Aerogel material sample in its "green" state. Aerogels are among the lightest solid materials known to man. They are created by combining a polymer with a solvent to form a gel, and then removing the liquid from the gel and replacing it with air. Aerogels are extremely porous and very low in density. They are solid to the touch. This translucent material is considered one of the finest insulation materials available.

KENNEDY SPACE CENTER, FLA. - James E. Fesmire (right), NASA lead engineer for the KSC Cryogenics Testbed, works on Cryostat-1, the Methods of Testing Thermal Insulation and Association Test Apparatus, which he developed. At left is co-inventor Dr. Stan Augustynowicz, chief scientist with Sierra Lobo Inc. in Milan, Ohio. Cryostat-1 provides absolute thermal performance values of cryogenic insulation systems under real-world conditions. Cryogenic liquid is supplied to a test chamber and two guard chambers, and temperatures are sensed within the vacuum chamber to test aerogels, foams or other materials. The Cryostat-1 machine can detect the absolute heat leakage rates through materials under the full range of vacuum conditions. Fesmire recently acquired three patents for testing thermal insulation materials for cryogenic systems. The research team of the Cryogenics Testbed offers testing and support for a number of programs and initiatives for NASA and commercial customers.

In the Payload Hazardous Servicing Facility, Randy Scott (left) and Pat Wedeman (right), with Lockheed Martin Astronautics, check the insulation material on the <a href="http://www-pao.ksc.nasa.gov/kscpao/captions/subjects/stardust.htm">Stardust</a> spacecraft. Stardust will use a unique medium called aerogel to capture comet particles flying off the nucleus of comet Wild 2 in January 2004, plus collect interstellar dust for later analysis. The collected samples will return to Earth in the SRC to be jettisoned as it swings by Earth in January 2006. Stardust is scheduled to be launched aboard a Boeing Delta 7426 rocket from Complex 17, Cape Canaveral Air Station, on Feb. 6, 1999
