When the Mars Orbiter Mission launched yesterday, it launched into Earth orbit. The Mars Orbiter Mission must perform several rocket burns in order to increase its orbital altitude before departing for Mars. The first burn was completed successfully just minutes ago.

The European Space Agency has selected two astrophysics observatories as its next large science missions, overlooking every proposed planetary mission. ESA's current selection of planetary missions, however, means it will still be a major player in solar system exploration for the next two decades.

As fall began to give way to winter at Endeavour Crater, Opportunity cruised deeper into her campsite on the western side of Solander Point in October, heading for a site that may contain clay minerals and the rover's next big discovery, and the Mars Exploration Rovers mission trekked another month closer to its 10th anniversary in January 2014.

Deep in the main asteroid belt between Mars and Jupiter, Dawn is continuing its smooth, silent flight toward dwarf planet Ceres. Far behind it now is the giant protoplanet Vesta, which the spacecraft transformed from a tiny splotch in the night sky to an exotic and richly detailed world.

You may have noticed that Comet ISON appears to have a green halo in some recent images, but in other images acquired at about the same time, it doesn’t. Thanks to the beautiful new spectrum posted earlier today by Christian Buil, it’s relatively easy to understand why.
