At number 14 on IE's 22 best innovations of 2022, is a new heatshield technology from NASA that's helping put out fires.
This technology could prove vital due to the dangers of entering a planet's atmosphere that has different conditions to Earth. Mars' atmosphere, for example, is much thinner than Earth's and the descent of NASA's Perseverance rover into its atmosphere was famously described as "seven minutes of terror".NASA's six-meter-diameter LOFTID aeroshell acts as a massive brake system, creating much more atmospheric drag than traditional, much smaller aeroshells.
The space agency adds that the heatshield has "three layers: an exterior ceramic fiber cloth layer to maintain integrity of the surface, a middle layer of insulators to inhibit heat transmission, and an interior layer that prevents hot gas from reaching the inflatable structure. The flexible thermal protection system is also foldable, packable, deployable, and tailorable."
LOFTID is one of many examples of technologies built for space that could also have incredibly important practical applications on Earth. The heat shielding material developed for LOFTID, in fact, has already been used to build ato help tackle forest fires. NASA has worked with the U.S. Forest Service's Missoula Technology and Development Center to develop more effective fire shelters to save lives, meaning their heat-resistant material could save human beings in space and on Earth.
