How the SpaceX Crew Dragon spacecraft will bring us back to space

SpaceX just got its first crewed spaceship contract from NASA for the Crew Dragon spacecraft and it’s set to bring us back to space on American spaceships after so many years without. Along with the Boeing Starliner, the Crew Dragon will start making crewed space flights in 2017. For reference, the last flight of the… »Today 3:30pm11/25/15 3:30pm


The Amazingly Creepy Way Mars Will Kill Its Moon

It was a rough month for Phobos, as astronomers decreed—yet again—that Mars is ripping its lumpy moon apart. But apparently, Phobos’ loss is the Red Planet’s gain. After the satellite is torn to pieces, its fragments will fan out into a disk and 20 million years from now, Mars will become a ringed planet. »Today 10:30am11/25/15 10:30am

A Swarm of Satellites Will Soon Keep Us Safe From Fires

The GIF above, created by NASA, may leave you wondering why our government is building a planetary shield. Something you’re not telling us, NASA? According to the space agency, NASA’s shield plan has nothing to do with intergalactic threats—it’s protection against a danger on the ground.

The First Time NASA Docked with a Soviet Spacecraft in Orbit

Two spacecraft drifted closer to one another far above planet Earth, as they prepared to dock. It was July 17th, 1975, and they were about to make history. For the first time, a United States Apollo and Soviet Union Soyuz spacecraft would dock with one another, an enormously symbolic mission that served as a small… »11/18/15 2:00pm11/18/15 2:00pm

The Heart of this Elliptical Galaxy Exposes a Ghost From Its Past

Unlike spiral galaxies, with their flat shape and twisted arms, elliptical galaxies are featureless blobs without much structure. But then there’s NGC 3610—an elliptical galaxy with a bright and distinctly disc-like shape at its center. Astronomers say it’s a blast from this galaxy’s past, one that played an important… »11/16/15 7:00pm11/16/15 7:00pm

A Satellite Mishap Is Letting Physicists Test Einstein's Theory of Relativity

When life gives you lemons, make lemonade, right? That, at least, is the motto the European Space Agency seems to have embraced with respect to two wayward satellites, which are being repurposed to provide the most accurate assessment yet of how gravity affects the passage of time. »11/14/15 5:30pm11/14/15 5:30pm

This Newly-Discovered Dwarf Planet Is the Most Distant Object In Our Solar System

V774104: That’s the name of the new dwarf planet astronomers revealed this week, and it’s three times as far away from the sun as Pluto. It’s the most distant object ever discovered in our solar system—and it could mean there are even more far-flung planets in our corner of the universe just waiting to be discovered. »11/12/15 8:00pm11/12/15 8:00pm
