The OSIRIS-REx spacecraft's name has been changed to OSIRIS-APEX for its new mission to asteroid Apophis. See its journey to the asteroid in this orbit animation. Credit: NASA's Scientific ...

For an hour, HERA flew as close as 5,600 kilometers from the Martian surface, at a speed of 33,480 kilometers an hour. It ...

Comparing the before and after maps would provide clues to how asteroids like Apophis are assembled — vital information if we ever need to deflect one. NASA also has perfectly good asteroid ...

NASA and the European Space Agency are also interested in getting a better look at Apophis before and during its close approach to Earth in 2029. Though both YR4 and Apophis are no longer a risk ...

NASA and the European Space Agency also plan to send uncrewed spacecraft to observe Apophis in the years ahead to map and study its surface to gain further insights into near-Earth asteroids.

The chances of asteroid 2024 YR4’s odds of colliding with Earth in 2032 have dropped to nearly zero, thanks to new ...

Astronomers have been keeping a close eye on an asteroid between 130 and 300 feet long that has a very small chance of crashing into Earth in less than eight years. And as they learn more about ...

Now, just as the infamous cruise ship-sized Apophis was eventually ruled out as a threat to Earth, so too has 2024 YR4.

With clever rocket science, NASA redirected OSIRIS-Rex so that it will catch up with Apophis just days after its closest encounter to Earth. Using the same billion-dollar instrument suite designed for ...
