People on the ground in the Eastern Hemisphere will be able to observe the asteroid with their own eyes, weather permitting, according to NASA.

Live coverage of Artemis 2's splashdown begins this evening as four astronauts return from their historic 10-day mission around the moon.

The moments of reverence, camaraderie, and bravery we’ve witnessed since the launch of NASA’s Artemis 2 mission have done wonders for my faith in humanity, but sadly, all good things must come to an end.

Two new proposed NASA Earth science missions will attempt to address key research topics while leveraging both commercial and exploration capabilities. During NASA’s “Ignition” event March 24, the agency announced two new Earth science mission concepts,

In April 2029, asteroid Apophis will pass Earth at a distance that sounds almost unreal on paper. About 20,000 miles away from the surface, close enough that it sits inside the region where many satellites already orbit.

But as we prepare to observe another Earth Day, it’s important to know the impact of the planet’s dimming is real. Key to understanding all this is albedo, the measure of how much sunlight a surface reflects.
