"Some options are better than others. The cost and complexity of human space exploration demands that each element be measured by its value towards the ultimate goal: Mars. But NASA's stated next priority will not contribute to that aim. Its Asteroid Redirect Mission (ARM)2 is a multibillion-dollar stunt to retrieve part of an asteroid and bring it close to Earth where astronauts can reach it. It will require an ancillary spacecraft deploying either a huge capture bag or a Rube Goldberg contraption resembling a giant arcade-game claw. Neither technology is useful for getting humans to Mars."
