NASA unveils plan to catch asteroid as step to Mars flight

CAPE CANAVERAL, Florida, Apr 11:   President Barack Obama wants NASA to start work on finding a small asteroid that could be shifted into an orbit near the moon and used by astronauts as a stepping-stone for an eventual mission to Mars, agency officials said yesterday. The project, which envisions that astronauts could visit such an asteroid as early as 2021, is included in Obama’s 17.7 billion dollars spending plan for the US space agency for the 2014 fiscal year.
