We've all seen videos of satellites being blasted off into space - but once they're locked in orbit around the earth, how do we bring them back down?
Tiny CubeSats are ready to be our eyes in the skies.

As technology advances, tiny satellites no bigger than a loaf of bread have advanced from just proving they work to being big contributors in answering science questions.
John Glenn stands in the NASA mailroom surrounded by thousands of letters sent to him.

Letters from would-be girl astronauts in the 1960s tell part of the complicated story of sexism – in both NASA and the US at large – at the dawn of the space age.
Enjoy the full moon’s glow.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you've observed over the years.
Truth is out there.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
An artist’s impression of a transiting Jupiter-mass exoplanet around a star slightly more massive than the sun.
Many of the new planets found in other star systems have some extraordinary orbital behavior. So what's going on?
Unmanned rocket explodes moments after launch.
Cheap, affordable space travel would be revolutionary. Chances are, when it comes, it won't rely on the brute force approach of rockets.
Neutrinos, we’re looking for you! Japan’s Super-Kamiokande detector.

The Nobel Prize-winning research on neutrinos is expected to push the boundaries of science and technology.
Our moon orbits the Earth in the same way satellites do.
Take a look at the moon and it isn’t hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on…
