Quest Thermal, working with our client, has designed a lightweight thermal insulation system that provides low heat leak in-air on ground, and improved performance at high altitudes.  Structural discrete spacers self support a thin vacuum shell, providing heat flux as low as 0.3W/m2, and estimated LH2 mass fractions near 80%.

Quest Thermal has designed, built and tested a novel Mars surface liquefaction insulation system.  Demonstrated on a 400L 30" diameter tank, MultiEnvironmentMLI (MEMLI) offers low heat flux in-air, during in-space cruise, and on Mars surface. Discrete spacers support 10mil to 16mil Al vacuum shells, allowing a 10layer MEMLI system to have a heat leak of 0.233W/m2 (90K LOX, 210K, Mars ambient pressure) with a low mass of 1.8kg/m2.  NASA's Mars surface liquefaction team heat flux goal was1.5W/m2.  MEMLI is a lightweight, effective, high performance thermal insulation system that operates well...

Quest's IMLI has been designed into a large scale HLS ground test, with testing occuring at Marshall.  IMLI was custom designed for the spherical tank to minimize heat flux and help optimize vapor cooling.

Quest's IMLI is helping reduce heat leak from NASA's Lunar Environment Monitoring Station (LEMS), a lunar surface science payload. IMLI's high performance on a LEMS mockup enables reduced internal spacecraft heating units (RHUs) and allows the spacecraft to survive the long, and cold, lunar night.

Quest Thermal, in a six month NASA SBIR Phase I program, designed, built and tested a 0.3m diameter prototype of a new ultra-lightweight dual vacuum shell LHe dewar. NASA has need of a lightweight dewar for LHe cooled stratospheric balloon observatories. A conventional 4m diameter dewar is 2676kg, a Quest dewar would be 268kg, with heat leak reduced from 1.8W/m2 to 0.32W/m2 with Quest Light Weight Dewar (LWD) technology. LWD is at TRL4, and reduces the mass of a LHe dewar to well within the lift capability of a stratospheric balloon, enabling future 4m fully cryogenic far-IR telescope... Read More

Quest Thermal’s Integrated MLI (IMLI) is an advanced, next generation multilayer insulation. IMLI had its first spaceflight in December 2018 on NASA’s Remote Refueling Mission 3. RRM3 is a flight experiment on the ISS to test cryogenic storage and transfer. Source and receiver dewars contained LCH4, the receiver dewar was insulated with IMLI. IMLI accommodated a complex geometry varying from 2 to 21 layers, with spacial constraints such as G10 shroud.  There was excellent agreement between modeled and measured heat leak (calculated 0.517W, measured 0.515W).  New technologies were developed...

Quest Thermal is happy to announce the addition of mechanical engineer Tim Heidersheit.  Tim brings new talent, and isa great addition to Quest's engineering group!  Tim has contributed to several Quest insulation R&D programs, including Vapor Cooled Structure MLI, Variable Gas Radiator, and Multi-Environment MLI.  Tim has good part design skills, produces new parts and fabrication fixtures, has good analytical skills, and helps with our thermal vacuum testing.

Quest's Alan Kopelove presented a paper on Quest Multi-Environment MLI, a new insulation tuned for operation on Mars to the Space Cryogenics Workshop. This biannual conference of NASA and space cryogenics researchers, sponsored by the Cryogenics Society of America and NASA, allows researchers to meet and discuss the latest developments.

In May 2017 Quest had three new concepts selected for award by NASA.  This is great news, and allows us to move forward with three unique thermal control systems for future NASA and commercial use. One contract advances our on-Mars surface "Multi-Environment MLI", an ultra high performance low mass insulation able to operate in Mars atmosphere to protect LOX produced on Mars surface via ISRU. Two contracts were to develop novel "Variable Conductance Radiators" - highly variable spacecraft radiators.  Radiators help control the thermal environment in a spacecraft, with the "turndown ratio" a...

NASA's Robotic Refueling Mission 3 (RRM3) team selected Quest IMLI to insulate the receiver/dewar for use in an ISS flight experiment. This will likely be the second IMLI spaceflight.  RRM3 is developing new methods for refueling satellites and space instruments for longer operational life.  IMLI was designed, installed, tested and validated on a ground test article. IMLI was then installed on flight hardware, tested, and provided for integration into the RRM3 experiment pallet, IMLI heat flux was modeled to be 0.515 W through the blanket, with a measured heat flux of 0.517 W.
