Breathtaking space images inspire us. But what if you couldn't see them? Amelia Ortiz Gil explains how tactile models of the constellations, moon and planets can give people - blind or sighted - a better appreciation of the universe.

The walking and hopping SpaceBok robot is being tested now in ESA's Mars Yard, in the Netherlands. Someday these little robots might help explore the moon, or Mars.

After cruising along behind NASA's InSight for 7 months, the 2 briefcase-sized spacecraft successfully relayed data back down to Earth from Insight during its descent to the Martian surface on Monday, November 26.

Russian entrepreneur and physicist Yuri Milner wants to send a probe back to Saturn's ocean moon Enceladus, to search for evidence of life there. NASA wants to help him.

This comet is due to pass closest to our sun and Earth in December 2018. It's already the brightest comet in the night sky, visible to astronomers with telescopes and binoculars. A new image shows the comet's rotation!

There's a new robot on Mars' surface, the InSight spacecraft, designed to study the planet's interior. It set down safely Monday after nearly 7 months of flight from Earth and a 7-minute nail-biting plummet through Mars' thin atmosphere.

Scientists used data sonification to transform a photo of the now-silent Opportunity rover's 5,000th sunrise on Mars into a piece of music.

There's a reason space engineers describe landing on Mars as "7 minutes of terror."

Signals from Mars will take 8 minutes to travel to Earth on Monday. By the time we hear that InSight has reached the top of Mars' atmosphere, the lander will have already touched down safely ... or crashed.

On November 26, 2018, NASA’s InSight lander will make its daring descent to Mars' surface. NASA engineers hope to broadcast word of a successful touchdown at 20:00 UTC (3 p.m. EST), with live landing commentary starting about an hour before.
