Spacecraft orbiting Mars can reveal small features on the planet's surface, but there are only so many things you can see from above. When a meteor strikes the surface of Mars, it can excavate sub-surface material, allowing scientists to study what lies beneath. Researchers have simulated various impacts on Mars, changing the sub-surface material from bedrock to water-ice glaciers, and then calculated what should be visible after an impact, enabling new science.

Houston-based startup Venus Aerospace just launched the first successful test flight of a rotating detonation rocket engine (RDRE) test from U.S. soil.

Scientists have discovered 26 previously unknown bacterial species in the clean rooms that were used to prep NASA's Phoenix Mars lander for its 2007 launch.

India attempted to launch an Earth-observing radar satellite on Saturday (May 17) but a problem with the mission's rocket resulted in a failure.

Earth's magnetosphere channels particles from solar storms into stunning auroras. Mars lacks a planet-wide magnetic field and has patchy auroras barely detectable with instruments. Or so we thought. New images captured by NASA's Perseverance Rover with its Mastcam-Z instrument show green auroras in visible light. When humans finally walk on Mars and look to the skies, they could possibly see faint auroras there, too.

A familiar face from ancient "Doctor Who" history makes an unexpected return.

The Emmy-winning animated anthology returns, and we've scored every exceptional short from bottom to top.

Building a sustainable economy on the moon won't be easy, but we at least have some ideas about how to get started.

On Episode 161 of This Week In Space, Rod Pyle and Tariq Malik catch up on headlines ... and space dad jokes!

India will launch an Earth-observing radar satellite tonight (May 17) on the nation's second mission of 2025, and you can watch the action live.
