NASA’s Orion Crew Exploration Vehicle heat shield candidate materials have just been tested under intense heat conditions, to see how they would hold up during Orion’s return and re-entry from a lunar mission. Philip Lorenz III reports that NASA engineers who specialize in arc heater testing teamed with the Arnold Engineering Development Center in Tennessee to modify the center’s High Enthalpy Aerothermal H2 test facility to accommodate the testing.
The Air Force is spending heavily on F-22 improvements through the end of the decade, suggesting it may not retire the jet in 2030 as it previously planned. New sensors, fuel tanks, communications, and electronic warfare systems are among the upgrades that comprise the package.
