Lakdawalla, Emily S.

This was a big week in space, from Curiosity stumbling upon sulfur crystals to an exoplanet discovery and a major advocacy effort.

The gas giant is the Solar System's largest planet. Here's why it's also the fastest-spinning planet.

NASA has canceled VIPER, a rover designed to seek out water ice and other resources in the lunar south pole.

A comet collided with Jupiter 30 years ago, and the resulting images still inspire awe and wonder today.

One rocket could decide how soon humanity returns to the Moon — and maybe one day sets foot on Mars.

If passed, it would be the first standalone NASA authorization since 2017.

Rockets are an integral part of spaceflight, and this week they get the attention and admiration they deserve.

From the dangers of radiation to the complications of landing a crewed spacecraft, there are myriad technical challenges facing human exploration of Mars.

The House would provide a 1% increase to NASA while shifting funding toward larger programs, leaving significant budgetary holes in smaller programs.

From taking hundreds of thousands of photos of Mars to scanning the skies for asteroids, humanity is keeping an eye on our cosmic neighborhood.
