US engineers test ‘sweaty’ spacecraft tech to make rockets reusable as air travel
SMRTR summary
Engineers are testing a new spacecraft skin that releases coolant gas to protect against reentry heat, potentially eliminating the need for heat shields. This "sweaty" technology, backed by a $1.7 million Air Force grant, could make spacecraft as reusable as aircraft, drastically reducing turnaround times and increasing mission frequency.
