NASA probe enters the tightest orbit ever around a planetary object

NASA’s OSIRIS-REx mission to the asteroid Bennu has already brought about a series of landmark moments for space exploration, not least of which is the fact that the rock currently stands as the smallest object ever orbited by a spacecraft. N… Continue reading NASA probe enters the tightest orbit ever around a planetary object

Huge metallic anomaly detected buried beneath the Moon's largest crater

The huge South Pole-Aitken basin on the Moon can be seen in this topographical map, as ...

Although it looks like a boring, barren place, the Moon is home to some pretty amazing landmarks. The South Pole-Aitken basin, for example, is the largest impact crater in the solar system, measuring about 2,500 km (1,550 mi) across at its widest point. And now scientists have detected something strange buried under the crater.

Close encounter with alien star could explain ’Oumuamua, debunk Planet Nine

Our solar system has several “belts” of rocky planetesimals that are essentially the crumbs left over from the formation of the planets and moons. But new research suggests some of them could actually be alien, captured during close flybys wi… Continue reading Close encounter with alien star could explain ’Oumuamua, debunk Planet Nine

The Science of Landing on an Asteroid

TL;DR – Very, very gently.

Exploiting the resources of the rock-strewn expanse of space between Mars and the outer planets has been the stuff of science fiction for ages. There’s gold in them ‘thar space rocks, or diamonds, or platinum, or something that makes them attractive targets for capitalists and scientists alike. But before actually extracting the riches of the asteroid belt, stuck here as we are at the bottom of a very deep gravity well that’s very expensive to climb out of, we have to answer a few questions. Like, how does one rendezvous with an asteroid? What’s involved …read more
