NASA's Flat Budget Requires Hard Choices, And the choice is Asteroids
NASA announced Monday a $17.7 billion budget request for fiscal year
2013. The budget does not enable NASA to move forward with the planned
2016 and 2018 ExoMars missions in collaboration with the European Space
Agency.

While the budget supports a program of space exploration that will build on new technologies and proven capabilities to expand America's reach into the solar system, this budget does not enable NASA to move forward with the planned 2016 and 2018 ExoMars missions in collaboration with the European Space Agency.

Planck All-Sky Images Show Cold Gas and Strange Haze
New images from the Planck mission show previously undiscovered islands
of star formation and a mysterious haze of microwave emissions in our
Milky Way galaxy. The views give scientists new treasures to mine and
take them closer to understanding the secrets of our galaxy.
Planck is a European Space Agency mission with significant NASA participation.
"The images reveal two exciting aspects of the galaxy in which we live," said Planck scientist Krzysztof M. Gorski from NASA's Jet Propulsion Laboratory in Pasadena, Calif., and Warsaw University Observatory in Poland. "They show a haze around the center of the galaxy, and cold gas where we never saw it before."
The new images show the entire sky, dominated by the murky band of our Milky Way galaxy. One of them shows the unexplained haze of microwave light previously hinted at in measurements by NASA's Wilkinson Microwave Anisotropy Probe (WMAP).

Project NEOShield
Over the next three years, the NEOShield project will investigate how to
prevent dangerous impacts with asteroids and comets that could befall
the Earth in the future. The study could also lead to a better
understanding of the composition, structure and surface texture these
space objects.
