SpaceX and a rival company are rushing ahead with plans for constellations of thousands of satellites, but regulators might not be ready.

NASA's Charlie Sobeck, former manager of the Kepler Space Telescope mission, discusses the monumental findings of the spacecraft and NASA's decision to retire it in orbit.

Amber Gee viewed aerial images of the hurricane-ravaged Florida Panhandle and noticed a distress signal outside her grandmother's house.

A team of volunteer space cowboys may have to say goodbye to ISEE-3 and to their dream of reviving for a final mission the creaky, 36-year-old hardware. Failed tests Wednesday suggest a fuel problem.

So far, so good. ISEE-3, the versatile 1978 space probe that took a detour to greet a comet in the 1980s, is now on track to get close to the moon, scientists say, though course fixes can be tricky.

Keith Cowing discusses his campaign to save an old '70s NASA spacecraft from becoming space junk. Cowing and his colleagues are turning to crowdfunding to wake up ISEE-3/ICE and put it to good use.

In the 1980s, NASA engineer Robert Farquhar came up with a sly plan to divert the ISEE-3 satellite from its original path to visit a comet instead. Now Farquhar has another big plan for his "baby."
