Hera

Hera is on its way to investigate the aftermath of our collision with an asteroid. But first it flew past Mars. See the new Mars and Deimos pics here. The post New Mars and Deimos pics from revealing Hera flyby first appeared on EarthSky.

From action figures and art books, to house decorations and phone cases, here is all the official War of the Rohirrim merch you can buy now at Amazon.

NASA's Orion spacecraft is designed to keep astronauts safe in deep space, protecting them from the unforgiving environment far from Earth. During the

Hera will arrive in 2026 at Dimorphos, an asteroid deliberately struck by NASA's DART spacecraft

Hera will take a close look at asteroid rammed by NASA spacecraft 2 years ago

SpaceX launched the European Space Agency's Hera spacecraft on Monday to see a test NASA performed in 2022 to knock the moonlet off its orbit from an asteroid actually worked.

Most CubeSats weigh less than a bowling ball, and some are small enough to hold in your hand. But the impact these instruments are having on space exploration is gigantic. CubeSats – miniature, agile and cheap satellites – are revolutionizing how scientists study the cosmos.A standard-size CubeSat i...

CubeSats have already visited the Moon and Mars and are key components of upcoming deep space missions.

The danger posed by radiation is a major concern that must be addressed if astronauts are to carry out long-term missions beyond Earth's orbit.

With the help of mannequins named Helga and Zohar and sensors placed inside a spacecraft, scientists have collected valuable data about radiation exposure...

Scientists have analyzed images of the twin asteroids Didymos and Dimorphous taken by NASA's DART mission before it impacted the smaller space rock...

"It will miss the Earth. It will miss the Earth. It will miss the Earth."

Thirty years ago, on 16 July 1994, astronomers watched in awe as the first of many pieces of the Shoemaker-Levy 9 comet slammed into Jupiter with incredible force. The event sparked intense interest in the field of planetary defense as people asked: "Could we do anything to prevent this happening to Earth?"

The lighting of the Olympic flame took place in Greece this morning in advance of the Paris 2024 games. Here's what to know and how to watch.

The DART mission has proven that we can substantially affect potentially hazardous asteroids.

Expect lots of space missions to launch this coming year, with exciting new science to follow.

NASA's OSIRIS-REx mission taught astronomers how little they know about space rocks. They might be only a few hundreds of feet wide, but their geology...

The asteroid Dimorphous, three months after it was hit by a spacecraft

The European Space Agency's Hera spacecraft is now assembled ahead of its journey to analyze the asteroid smashed by NASA's DART mission.

The radar component for a CubeSat is being sent to study asteroid Dimorphos has been delivered to ESA for integration with its spacecraft.
