Message to Attendees of the 2013 IAA Planetary Defense Conference

NASA's Mars rover Curiosity is in good health but takes a short break while engineers diagnose why it reset its computer.

The highest resolution images offer about 110 feet (33 meters) per pixel.

Scientists have synthesized a molecular system that, like DNA, can store and transmit information. This suggests there could be a genetic system for life that may be possible on other worlds.

NASA has selected 12 science and technology demonstration payloads to fly to the Moon as early as the end of this year.

Congratulations to SpaceIL and the Israel Space Agency. This is a historic step for all nations and commercial space.

An Israeli mission will take a shot at the first private Moon landing, and NASA is contributing to the experiment.
