The Orionids peak tonight. Wait for the Moon to get out of the way
The October 21–22 meteor shower favors a dark interval before dawn. NASA’s sky chart and realistic viewing rates help make the early start worthwhile.
A thinner rotor profile could give future Mars helicopters more room to fly
Wind-tunnel tests and simulations favor a Mars-specific airfoil. The long-range figures describe future designs, not a flight already achieved.
NASA’s next Moon rovers have to pass the wheel-and-spacesuit test first
The October update separates mockups, design reviews and future lunar delivery. Remote operation makes these vehicles more than astronaut transport.
NASA names the machinery that will turn SR-1 Freedom’s reactor heat into power
Sierra Lobo will supply the conversion system for the planned 2028 mission. The reactor and the electric spacecraft still have to prove themselves together.
NASA launches commercial relay trials: the next test is the connection
Viasat and SES will test different routes for science data and spacecraft commands. Reaching orbit begins the demonstration; it does not certify a replacement network.
Inside X-59's inlet: the maintenance behind NASA's quiet-supersonic tests
A newly published account explains inspections filmed in April, while the aircraft's latest flight report still places it in envelope-expansion testing.
Hubble's NGC 1827 image puts a foreground star in the spotlight
The edge-on galaxy shares the frame with foreground stars, background galaxies and traces of the telescope's optics. Understanding those layers changes what the image shows.
NASA sharpens Roman’s focus as the telescope prepares for survey science
Instrument checks and optical adjustments are turning a launched observatory into a calibrated measuring system.
