  • President Barack Obama set a lofty next goal this week for Americans in space: Visiting an asteroid by 2025.
  • But reaching a space rock in a mere 15 years is a daunting mission, and one that might also carry the ultimate safety of the planet on its shoulders.
  • And there's another compelling reason for touching an asteroid: Saving the planet.

  • Scientists estimate there are about 100,000 asteroids and comets near Earth, but only about 20,000 are expected to pose any risk of impact.
  • 1,000 of them flying in orbits that could potentially threaten the Earth in the future, NASA scientists have said.
  • "By 2025, we expect new spacecraft designed for long journeys to allow us to begin the first-ever crewed missions beyond the moon into deep space," Obama said. "We'll start we'll start by sending astronauts to an asteroid for the first time in history."
  • "Robots have never discovered things," Grunsfeld said. "People have discovered things, using robots."

Neil Armstrong moonwalker Obama man on the moon apollo 11 Eugene Cernan Apollo 13 cancel nasa back-to-moon program blasts first

  • The first man to walk on the moon blasted President Barack Obama’s decision to cancel NASA’s back-to-the-moon program on Tuesday, saying that the move is “devastating” to America’s space effort.
  • The most controversial part of the president's policy is the cancellation of the Constellation program, which was aimed at developing a new generation of Ares rockets and Orion spacecraft to send astronauts into Earth orbit and beyond.
  • Obama administration determined that the Constellation program could not fulfill NASA's goals on the required timetable.

  • The letter notes that the U.S. space effort will be dependent for years to come on the Russians for transport to the International Space Station, at a cost of more than $50 million per seat.
  • Armstrong and his colleagues complained that the cancellation would amount to wasting the roughly $10 billion that has been allocated to Constellation over the past five years.
  • "America must decide if it wishes to remain a leader in space," the astronauts said. "If it does, we should institute a program which will give us the very best chance of achieving that goal.
  • The fact that Armstrong, arguably the world's most famous living astronaut, has now spoken out against NASA's change of plans is likely to focus additional attention on the debate over America's future in space.
  • On the other side of the debate, the most outspoken Apollo-era advocate of NASA's new policy is the man who was Armstrong's co-pilot for the first moon landing: Buzz Aldrin.

      i find this interesting how the first two men on the moon, co-pilots, respond with such dichotomy when considering this topic.
