Looks like a pair of "miner 49'ers" have been quietly traversing the solar system on their "burro"...

https://www.bbc.co.uk/news/science-environment-455...



"Japan's space agency is preparing to deploy two robotic explorers to the surface of an asteroid.

On Friday, the Hayabusa-2 spacecraft will despatch a pair of "rovers" to the 1km-wide space rock known as Ryugu.

Rover 1A and Rover 1B will move around by hopping in Ryugu's low gravity; they will capture images of the surface and measure temperatures.

Hayabusa-2 reached the asteroid Ryugu in June this year after a three-and-a-half-year journey.

If all goes well, Hayabusa-2 will be the first spacecraft to successfully place robot rovers on the surface of an asteroid.

The 1km-wide space rock known formally as 162173 Ryugu belongs to a particularly primitive type of asteroid, and is therefore a relic left over from the early days of our Solar System. Studying it could shed light on the origin and evolution of our own planet.

The rovers are stored in drum-shaped container at the base of the Hayabusa-2 "mothership". Collectively, they form a 3.3kg science package known as Minerva II-1...."

Thanks for posting, I've been following this for a long time and this is a really complicated mission, but does not have the wow factor of a big rocket taking off but is really cutting edge with so many parts and so many failure points.

BBC now reporting it

https://www.bbc.co.uk/news/science-environment-455...

They have a French - German bouncer to be dropped soon as well ---- Mascot https://www.youtube.com/watch?v=8H4aZX_8hMA

Great overview of the entire mission and how each of the 3 landers /bouncers around in low G for little power. So cool!

This is the pdf diagram of the first 2 bouncer releases.




They obviously adjusted the software on the LIDAR so it did not make the craft start to rise again at 600m as before on their test shot for it a week or so back due to the asteroid being so dark. Always good to practice. Now went to proper 60m and got the packages down pat. Well done! yesthumbup

Main website here,

http://www.hayabusa2.jaxa.jp/en/

The pdf of what they have planned is here

http://www.zen141854.zen.co.uk/sat.pdf

The impactor on page 33 is similar to weapons against tanks. A lining gets forced into a projectile shape and is 2km/s within 1 meter! Page 91 onwards is very clever. Diagrammatic of how they will do the impactor test on page 94 including releasing a small camera pod and hiding the maincraft. Lots of things that can go wrong even there, and that is one small part. I do hope they can then land and get their sub surface samples home perfectly.

Just epic.

Agreed - such a complex mission, fascinating to see how it plays out. We do brilliant stuff when we put our minds to it.

I've been following this too. They've got two rovers successfully landed, moving about and transmitting data from Ryugu.

Here's a Michael Bay-esque photo from one during a "hop" biggrin

They successfully deposited the 3rd lander 'Mascot' onto Ryugu this morning.

Nice summary for the Mascot landing from DLR, the European side of the mission

Trajectory on the way down and the "bouncing to a halt" and then hopping after that



Shadow of a TIE fighter taking an interest in proceedings.....

I believe the actual impact (perhaps not the best choice of words lol) of these images are being diminished [after all it's nothing a few geeks couldn't knock up with Photoshop].....

....the fact that we can get live stream from ascending rockets, stills and video from a frigging asteroid.... the amount of effort and technology to get the image capture devices in location in the asteroid belt is perhaps being overlooked by many...I can still (just about) remember the effect those grainy black and white moon pictures had in the early 60's the feelings of both awe and inspiration that fired a generation of young minds....

Latest images from Hayabusa on the near approach test run for next years actual touch down followed by a very audacious blasting of the surface while the main craft moves out of the way, leaving a camera behind, before picking up the sample and returning to earth.

This is the most complicated mission flying currently in space for goals.

Currently on its decent to Ryugu @ about 10cm/s and less than 3000m to go.


Looks like there is a live webcast on youtube from 21:45

They are about to do the most difficult part of the mission, firing the impactor, dropping and camera off to record it whilst the main craft "hides" from flying debris, from page 9 onwards of the below.

http://www.hayabusa2.jaxa.jp/en/enjoy/material/pre...

This pdf also contains some nice other info on the impactor on page 23 and the camera it is dropping off as well.

Twitter feed here.

It is currently descending slowly to it's impactor drop off point

It will be on youtube etc but seems to be 1.30am this morning, so hopefully the gin will last that long ....

I hope it goes well for them, it's been an amazing missing so far. beer

Well I tried to stay up late but Zen internet and their suppliers decided to do a 10pm to 6am maintenance!

Looks like everything went well with various craft separations, however no confirmation the SCI fired and no video data from the dropped off cam.

I hope the explosives worked.

Well done DCAM3

https://twitter.com/haya2e_jaxa?ref_src=twsrc%5Etf...

The team absolutely delighted how it went ....

"From a tense SCI operation (& web relay) to delights of the DCAM3 images, it was a day of wild emotions. When the DCAM3 image was displayed in the operation room, applause spread like an express train, focussed on Project Engineer, Takaneo Saiki. It was heart warming! (by IES兄"


"At 16:04:49 JST we sent the command “Goodnight” to DCAM3. Images taken with the deployable camera will be a treasure that will open up new science in the future. To the brave little camera that exceed expectations and worked hard for 4 hours — thank you. (From IES兄)"



That is the low res camera by the way.

Bombed?

For fecks sake stop dumbing down BBC and sort of smacks of something. No bombing at all with this.

Jeez

Now officially more cross than xxxxxxxxxxxxxxx

What is wrong with just drilling a hole instead of excavating with plastic explosives?

Probably knocked the thing off course slightly and it will wipe us out at some indeterminate time in the future.

Drilling a hole requires a downward force - something lacking on an asteroid

Anyway, it's on its way back smile

My son recently saw the mockup on display in Japan - he was surprised at the size of it, he had imagined it was smaller

Fingers crossed for a safe delivery.


This has been the most advanced and successful space mission of the last few years ... so far. Fecking epic.

God Speed !
