Chang'e 4
« on: December 11, 2018, 02:34:44 AM »
Mildly surprised that that nobody has mentioned the Chan'e 4 mission currently  on the way to the moon for the first landing attempt since the successful Chang'e 3 landing in 2013.

Chang'e 4 will attempt a lunar far side landing and deploy a rover.  There is also a relay satellite in EM-L2, Quegiao, already in place.  This nice little video shows the whole mission sequence https://pbs.twimg.com/ext_tw_video_thumb/1071741340134850560/pu/img/kXwG9c9d_iYtGVjd?format=jpg&name=small

The launch video can be viewed at

Very much looking forward to seeing how this turns out. China will have boots on the ground before long.

At least someone is forward looking.  :(

And the great thing about sending spacecraft to the Moon: you don't have to wait months or years for them to get there.

I can already see the CT's hand-waving again because China won't find a Apollo landing site on the far side of the moon  ::)

Of course not - they've gone there to photograph all the alien bases...  8)

Link by the Queqiao relay satellite in L2 established.  Artcie also has a lovely photo of the Earth and the Moon from a Saudi camera onboard one of the accompanying cubesats

Thanks for the update.  It's an exciting few days, between Chang'e 4 and New Horizons  :)

First image from the far side of the Moon after lander touched down.  Congratulations to the China Space Agency.

I managed to match the area on the landing sequence they've released with the LRO imagery:



The coordinates in the centre are -45.4564, 177.5963.

Kinda in the SW corner area with one medium crater leading to three more in a NE direction?

Good report here, note it uses Chang'e 3 images to illustrate surface operations, presumably because it was written before the rabbit escaped it's hutch.
