Spacecraft have long used heat shields for protection during entry into planetary atmospheres. Future missions to the outer solar system will need more sophisticated materials than currently exist. The extreme heating conditions needed to study new shield materials are, however, very difficult to achieve experimentally on Earth.

Today, the next-generation Geostationary Operational Environmental Satellite (GOES)-T successfully arrived at Kennedy Space Center, Florida, to begin launch preparations. It is the third of four satellites in the National Oceanic and Atmospheric Administration (NOAA)'s GOES-R weather satellite series built by Lockheed Martin [NYSE: LMT] in Littleton, Colorado.

After decades of inertial confinement fusion research, a record yield of more than 1.3 megajoules (MJ) from fusion reactions was achieved in the laboratory for the first time during an experiment at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF) on Aug. 8, 2021.

Future fusion reactors have a conundrum: maintain a plasma core that is hotter than the surface of the sun without melting the walls that contain the plasma. Fusion scientists refer to this challenge as "core-edge integration."
Researchers working at the DIII-D National Fusion Facility at General Atomics have recently tackled this problem in two ways: the first aims to make the fusion core

When the operations team logged on today, we were prepared to pick up where Monday's team had left off in Curiosity's ongoing drill campaign at Zechstein. But then we received some news: even though the original plan already included two hefty science blocks, the rover still had extra energy to spare!

Who hates deep sand traps more than golfers? Mars rover drivers (and probably Fremen too). When your vehicle is well over 50 million kilometers away from the nearest tow company, getting your wheels stuck in sand can be a mission-critical problem. Such a predicament ended the Spirit rover's mission in 2009.
Yet Perseverance is currently winding her way through the maze of towering sand dun
