Recently, NASA developed a plan to send a crew of astronauts to an Earth-approaching asteroid, called Prospects for Future Human Space Flight Missions to Near-Earth Asteroids. The plan has its origins in a speech delivered by President Obama at the Kennedy Space Center in 2010.
Obama’s remarks were meant to quell a firestorm he created when he canceled the Constellation Program, the last attempt to go back to the moon. As a consolation prize, he proposed sending a crew of astronauts to an Earth-approaching asteroid before launching a crewed expedition to Mars. The new proposal, not yet funded, is an updated version of the Obama plan, using the SpaceX Starship instead of an Orion launched from a Space Launch System rocket.
The Obama proposal was not a serious one. It quickly devolved into something called the Asteroid Redirect Mission, which envisioned diverting a small asteroid or maybe a boulder from an asteroid into lunar orbit, where it would be visited by an Orion with a crew. No one took the idea seriously.
Dr. Richard Binzel of MIT, one of the world’s leading experts in small, celestial bodies such as asteroids and comets, was especially scornful. Instead, he suggested a survey of Earth-approaching asteroids, some of which might prove to be a threat to Earth.
The Asteroid Redirect Mission died a quick and unlamented death when President Trump assumed office and started the Artemis program that redirected NASA to send astronauts back to the moon before sending crewed expeditions to Mars. Unlike previous attempts to return to the moon, Artemis has met with considerable technical and political success. Artemis 1, an uncrewed mission around the moon, succeeded brilliantly.
President Biden, soon after assuming office, made Artemis his own. A crew has been selected for the Artemis II circumlunar mission to take place no earlier than late 2024. READ MORE...
