NASA wants to give the Moon a moon
IT COULD BE NASA’s craziest idea yet: the agency is planning to drag an asteroid into a stable orbit around the Moon. Once there, it will be visited by astronauts who will test technology being developed for future human expeditions to deep space, including to Mars.
Dubbed the Asteroid Redirect Mission (ARM), thee project will involve guiding an unmanned spacecraft to a near-Earth asteroid. Robotic arms on the craft will then capture a 4m-wide boulder from the asteroid’s surface, before moving the whole shebang into orbit around the Moon. The craft won’t physically tow the asteroid: instead, it will use its own mass, combined with that always been unclear. Now, Duke University has found that male mice make the sounds to serenade females.
What did they find?
Males sang louder, more complex songs when they could smell a female’s urine, but could not see her. The songs were longer and simpler when the males of the boulder boulder, to exert a gravitational attraction on the asteroid and alter its path. In space, gravitational attraction can have a significant impact, even on fairly small objects. The journey is expected to take several years.
