“Tidal waves” power super-fast rotation of Venus’ atmosphere

An international team of scientists led by Takeshi Horinouchi of Hokkaido University suggests that an atmospheric equivalent of tidal waves may be responsible for the super-rotation of the atmosphere of Venus. Based on data returned by JAXA’s Akatsuki … Continue reading “Tidal waves” power super-fast rotation of Venus’ atmosphere

Earth to be buzzed this week by spacecraft heading to Mercury

This week Earth will be visited by a spacecraft that has traveled 1.4 billion km to get here. But no, it’s not aliens – it’s BepiColombo, a European-Japanese mission that’s just slingshotting around our planet for a gravitational speed boost on its rou… Continue reading Earth to be buzzed this week by spacecraft heading to Mercury

JAXA releases footage of Hayabusa 2 spacecraft's second asteroid touchdown

Hayabusa 2 moments after touching down on the surface of the asteroid

The Japanese Aerospace Exploration Agency (JAXA) has released a video showing the climactic moments of the Hayabusa 2 spacecraft’s second descent to the surface of asteroid Ryugu. The goal of the risky operation was to capture newly exposed material from the asteroid’s interior, which had been forcefully ejected during the creation of an artificial crater on Ryugu’s surface in early April.

Travel to Mercury on Ion Power

Star Trek — as much as we love it — was guilty sometimes of a bit of hyperbole and more than its share of inconsistency. In some episodes, ion drives were advanced technology and in others they were obsolete. Make up your mind!

The ESA-JAXA BepiColombo probe is on its way to Mercury riding on four ion thrusters developed by a company called QinetiQ. But unlike the ion drive featured in the infamous “Spock’s Brain” episode, BepiColombo will take over seven years to get to Mercury. That’s because these ion drives are real.

The craft is actually two spacecraft in …read more

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
