Uncertainty lingers on NASA's Mars program

This week’s arrival of NASA’s Mars rover Curiosity set the stage for a potentially game-changing quest to learn whether the planet most like Earth ever had a shot at developing life, but follow-up missions exist only on drawing boards.

The United States had planned to team up with Europe on a trio of missions beginning in 2016 that would culminate in the return of Mars soil and rock samples to Earth, an endeavor the National Research Council considers its top priority in planetary science for the next decade.

Citing budget concerns, the Obama administration terminated NASA’s participation in Europe’s ExoMars program earlier this year, spurring the U.S. space agency to re-examine its options before another flight opportunity comes and goes. Earth and Mars favorably align for launches about every 26 months.

The situation is complicated by massive budget overruns in the $2.5-billion US Curiosity mission, intended to determine if Mars could now or ever have supported microbial life, and in the $8 billion James Webb Space Telescope, a successor to the Hubble observatory.

US ends mission in Iraq: An unpopular conflict comes to an uncertain end

[ via The Times of India ] 15 Dec

The United States military officially declared an end to its mission in Iraq on Thursday even as violence continues to plague the country and the Muslim world remains distrustful of American power.

In a fortified concrete courtyard at the airport in Baghdad, Defense Secretary Leon E. Panetta thanked more than one million American service members who have served in Iraq for "the remarkable progress" made over the past nine years but acknowledged the severe challenges that face the struggling democracy.

The muted ceremony stood in contrast to the start of the war in 2003 when an America both frightened and emboldened by the attacks of Sept. 11, 2001, sent columns of tanks north from Kuwait to overthrow Saddam Hussein.

The tenor of the 45-minute farewell ceremony, officially called "Casing the Colors," was likely to sound an uncertain trumpet for a war that was started to rid Iraq of weapons of mass destruction it did not have. It now ends without the sizable, enduring American military presence for which many military officers had hoped.
