In a presentation, NASA associate administrator Robert Lightfoot laid out the agency's timeline for the missi air jordan 7, on: target selection in 2016, asteroid capture in 2019, and the first astronaut visits to the relocated rock in 2021.

As explained by Paul Dimotakis, one of the Keck scientists who worked on t air jordan retro 13, he project, the physics of the endeavor requires NASA to target a relatively small asteroid of 500 to 1,000 tons.

Asteroids come in many forms, from rubble piles barely held together by their jordans sneakers, own gravity to dense balls of iron and nickel. Dimotakis said the asteroid to capture needs to be the consistency of dried mud.

Finding the right asteroid to capture will not be easy, Dimotaki women nike dunk sb, s said. Because of the limited size and nudging or towing power of the capsule that will be sent to the asteroid, the rock itself cannot be more than 1,000 tons.

What's more, it needs to be on white jordans for women, a trajectory that would take it close to the Earth and moon even without a tow. The capture spacecraft, Dimotakis said, would not have enough power and fuel to dramatically change the direction of an nike hyperdunk tb, asteroid of 500 to 1,000 tons.

By far the largest concentration of asteroids in the solar system orbit in the main belt between Mars and Jupiter. But NASA will be looking for one in Earth's e nike aerofit high , xtended neighborhood.

Bolden and Dimotakis listed numerous reasons for undertaking the project, but emphasized three in particular.
