Mars

822 Martian days after landing, NASA’s Curiosity rover, carrying the Mars Science Laboratory, continues on its extraordinary journey across landscapes that are both utterly alien, and remarkably familiar.

Today marks the 50th anniversary of the launch of NASA’s Mariner IV spacecraft (November 28, 1964). In total, the mission gave us 21 complete images of Mars, including this, our first close view of the planet—courtesy of data transmitted by the interplanetary probe and earth-bound scientists wielding pastels (below).

Most audiences outside the beltway don’t immediately know I mean Research and Development – until I explain it’s the part of our federal budget accounting for a good deal of “science stuff.” R&D supports basic research and leads to new innovation while helping boost [...]

America's keystone human spaceflight mission for the next decade may be over before it begins

It was a big week for physics in the movies, with the premiere of Interstellar, and the Stephen Hawking biopic The Theory of Everything. That translates into lots of pixels commenting on the science behind the films.

On November 12th 2014 the European Space Agency’s Rosetta mission will eject the small robotic lander Philae on a trajectory that should take it down to the surface of comet 67P/Churyumov-Gerasimenko (or 67P/C-P for short).

The cause of the deadly crash of Virgin Galactic's SpaceShipTwo on Friday remains unknown, but the commercial spaceplane's feathered reentry system looks to have been involved.

We've come a long way since NASA's Mariner 4
