Japan Has Attempted To Land Two Tiny Rovers On a Distant Asteroid (arstechnica.com) 51

Posted by BeauHD from the suspense-is-killing-me dept.
On Friday, Japan's Hayabusa2 spacecraft attempted to deploy two miniature rovers on an asteroid that it's been orbiting since mid-August. Ars Technica reports: Each weighed only about a kilogram, and after separating from the main spacecraft they approached the asteroid named Ryugu. Japanese mission scientists think the rovers touched down successfully, but are not completely sure. Communication with the two landers stopped near the moment of touchdown. This is presumably because Ryugu's rotation took the rovers out of view from the Hayabusa2 spacecraft, but scientists won't know for sure until later Friday (or Saturday morning, in Japan) when they attempt to download images from the rovers. And thus we are left with a suspenseful situation.

    It's Saturday morning in the USA now, and it still hasn't been announced if they made it. When they spend this many hours not announcing success, that usually means there was a problem. Their Twitter feed [twitter.com] talks about the Hayabusa2 returning to its normal distance, but says nothing of the rovers.

    We are sorry we have kept you waiting! MINERVA-II1 consists of two rovers, 1a & 1b. Both rovers are confirmed to have landed on the surface of Ryugu. They are in good condition and have transmitted photos & data. We also confirmed they are moving on the surface. #asteroidlanding

    Rovers have beamed back images to Hayabusa2.

  • As I understand it the asteroid (Ryugu) is about 1km in diameter. What amazes me is that the landers can land in the first place.without drifting off and can have any moving parts without displacing themselves in the minuscule gravity. Obviously the Japanese understand all that and have made due allowance. Still it's impressive.

  • could not engineer a simple device with one job of retrieving an ore sample from a passing probe and returning to ISS? Really?!

If you could demonstrate an ability to at least read at an 12 year old level, and your less complex brain cavity could show us that you can go to another web page by clicking on the web anchor stated in TFA, then maybe we could clap at your performance of siting from the web article, return to Earth about a year later, landing in a remote part of Australia. all the while your handler generates sound using some hand cranked box.

        but you can

        • Perhaps if you knew anything about space exploration and orbital mechanics you might have an inkling of how much harder it would be to do what you're suggesting.

          If you could demonstrate an ability to at least read at an 12 year old level

          The problem is that you're not demonstrating an ability to write at the level of a 12-year-old.
