Virgin Galactic’s SpaceShipTwo will fly to space again today

Astronomy Magazine - 15 hours 51 min ago
On Friday, Virgin Galactic’s SpaceShipTwo will fly in space for the second time, taking off from Mojave, California, after days of weather delay. Their launch time is set for 8 A.M. PST. Unlike most spaceflights that fire rockets from the ground, SpaceShipTwo is carried on the back of a plane named WhiteKnightTwo before being released to propel itself into the upper atmosphere. It’s a suborbital flight, meaning it does not reach orbit, and attains weightlessness for only a few minut

Japan's Hayabusa2 is going to shoot an asteroid tonight

Astronomy Magazine - Thu, 02/21/2019 - 05:00
Far from Earth, a tiny spacecraft is going to punch an asteroid tonight. Hayabusa2 is swooping close to Ryugu today to collect asteroid dust. The JAXA spacecraft has spent the last day leaving its usual orbit around the asteroid to zoom in close. In just few hours, it will be close enough to touch Ryugu. But it won’t stay long. The touchdown is more of a quick tag, and Hayabusa2 will stay just long enough to fire a tiny bullet into the asteroid’s surface, in order to stir up material

The case for protecting the Apollo landing areas as heritage sites

Astronomy Magazine - Tue, 02/19/2019 - 05:00
Why did the hominin cross the plain? We may never know. But anthropologists are pretty sure that a smattering of bare footprints preserved in volcanic ash in Laetoli, Tanzania bear witness to an evolutionary milestone. These small steps, taken roughly 3.5 million years ago, mark an early successful attempt by our common human ancestor to stand upright and stride on two feet, instead of four. Nearly 50 years ago, Neil Armstrong also took a few small steps. On the Moon. His bootprints, along with
