http://earthsky.org/space/jaxa-confirms-2-rovers-landed-asteroid-ryugu http://en.es-static.us/upl/2018/09/RyuguByRover1BSept21.jpg Ryugu at approximately 55m altitude, photo taken by one of the two rovers right after release from Hayabusa2 Ryugu is a space rock with a diameter of approximately 1km, and it is classified as a potentially hazardous asteroid that occasionally comes near Earth. The rock and probe is 313 million km (194 million miles) from Earth. Communications from Hayabusa2 take 35 minutes to reach us. Ryugu's gravity is estimated to be 60,000 times weaker than Earth's gravity, and for that reason the tiny rovers hop and rotate over the surface instead of rolling across it continuously. In October, Hayabusa2 will release Mascot, a lander made by France and Germany, onto Ryugu. Hayabusa2 will be observing the rock until December 2020, when it will begin returning to Earth. Oh, and it's designed to bring samples back. http://www.planetary.org/blogs/jason-davis/hayabusa2-samples-names.html

first we studied them from afar, then we descended, next we destroy
Oh man I cannot wait to see the images these things will take
this is how spaceballs start, you first start putting balls in space.
Gee, Bill, two rovers?
the last article is shaking violently so for a second i thought it was a video of the "bouncing" rovers
it's so weird to look at an actual asteroid, you know that the physics of it make perfect sense, but still it's a bunch of apparently gravity-defying rocks held together for no visible reason
Two? It has total 4 landers. These are just cameras and temperature sensors etc. Next is a sampling rover that will take surface samples. Then they plan on placing some explosives on that bastard, to make a hole. Then it's gonna land into said hole, gather samples, and return them to earth.
I thought it starts by combing the desert.
OP vibrating makes this so much better

Here's a recording for those people who are not experiencing the seismic activity currently happening inside this thread: https://files.facepunch.com/forum/upload/180569/a935ecba-42ca-40bb-a091-fb589c808c4d/Shaking-2018-09-23_19.26.54.webm
Those are target markers Hayabusa2 will drop onto the asteroid and use for landing when it goes to collect a sample. The probe's lateral velocity needs to be exactly 0 relative to the 'roid when it goes to land, and it's going to use the markers as points of reference. They also contain the names of the Planetary Society's entire membership as of 2013.
its a very clever and conservative design since the exact composition of the surface and its scattering effects are unknown.
Hold on, if I embed the article again, do we get really crazy? Let's see. http://www.planetary.org/blogs/jason-davis/hayabusa2-samples-names.html
