The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
Satellites monitor climate change, guide people with GPS and keep us connected through texts and social media, but they're under threat.
New geological research reveals information about the Earth’s orbit and climate from billions of years ago.
Layers of rock provide a historical record of variations in the Earth's orbit, revealing information about the planet's climate billions of years ago.
A comet-gazing opportunity to close out the year.

A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
China’s Tiangong-1 space station is due to hit Earth, and Australia is in the crash landing zone.
Cindy Zhi/The Conversation
China's Tiangong-1 space station is hurtling around Earth out of control and about to come crashing down. It's just one of thousands of pieces of space junk left orbiting our planet.
What goes in doesn’t go out?
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
The SpaceX Falcon Heavy rocket takes off from Cape Kennedy in Florida, USA on 06 February 2018.
The launch of Elon Musk's Falcon Heavy rocket is undoubtedly a spectacular feat of engineering - but the release of a sports car into orbit also says something about our values as human beings.
time of moonrise and moonset and the shape of the Moon change throughout the month.

When and where you see the Moon in the daytime depends on what phase it is in.
As long as clouds don’t get in the way, the view should be spectacular.
A bunch of uncommon things all happening at the same time mean this full moon will have some special attributes.
Sunrise over Brisbane.
A solar day is a measure of how long it takes the Earth to rotate from one noon to the next, and today's summer solstice also happens to be the longest solar day of the year.
Without satellites, modern technologies such mobiles phones and GPS would not exist.

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.
Kamioka Observatory, ICRR (Institute for Cosmic Ray Research), The University of Tokyo
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…
