SpaceIL lands on the Moon... really, really hard.... ... but well done to them anyway!



My sympathies and congratulations to the SpaceIL team on the VERY hard landing of their Beresheet spacecraft on the Moon: The main engine cut out towards the end of the landing attempt - the engineers actually got it back online, but Beresheet had lost to much height and gained too much speed. The last recorded signal, as the engine came back, was still 100 meters up... but doing 150 meters a second. Just not enough distance to pull out of the dive. Even so, well done to them! To get so close is an astounding achievement, they still made their country the 4th nation to reach the lunar surface (although it was a private mission), and they really did fight it right to the finish - that was one of the most nailbiting 30 minutes of tweets I've ever read! 
Roll on Beresheet 2? 
Well... there's a good write up of the attempt here and it mentions the possibility. The ship took images (not great quality) before and during the attempt to land, which I've added below: 
 


On an even more successful note, SpaceX has launched it's super sized Falcon Heavy rocket for the second time, putting satellite cargo into orbit. What makes this a bigger achievement than a usual rocket launch is that the rocket, or at least the lower three quarters of it, has been landed afterwards for re-use! There're lots of cool pictures here, I've included a photo montage of the boosters landing seperately below, and I'll get a video up as soon as I can locate one that shows the whole launch end-to-end.

Juno snaps a storm on Jupiter, Israeli Moon missions nears landing, India's space weapon and more...


A cyclonic storm churns through Jupiter's northern hemisphere in this new view from NASA's Juno spacecraft. The swirling cloud formation looks a lot like a hurricane on Earth, with fluffy clouds popping up from the storm's spiral arms. Juno captured this view with its JunoCam imager on Feb. 12, when it was about 5,000 miles (8,000 kilometers) above Jupiter's cloud tops. — Hanneke Weitering

Fuel mining on the Moon could be worth billions, gigantic solar storms, and ancient people wiped out...


Lunar fuel mining?
This report (lunar propellant study) has found that there may be real fiscal legs on the idea of mining fuel for Earth orbiting satellites on the Moon.

New space station to open up the Moon?
NASA's increasingly realistic looking new space station, partway between the Earth and the Moon, gets a review here: Lunar gateway space station

What killed the Clovis people?
For a long time it's been suggested that the Clovis people of North America, who were wiped out along with much of the continent's mega fauna 13,000 years ago, were whacked by an asteroid strike - but the evidence has been lacking. New finds bolster the idea, here: Were the Clovis people wiped out by an object from space after all?

How bad tempered can our Sun be?
Our Sun has been know to spit out storms of radiation and magnetic fields that damage or disable satellites and even ground based communications, and the biggest on record have damaged power grids here on Earth. But they pale, so it seems, before some of the storms our local star has spat out in ancient times: Massive solar storm hit Earth in 660 BC

Lost Soviet space mission can be seen.
A failed cold war mission to Venus can be spotted in the night sky: Spot a failed Russian mission to Venus.

Strange structures seen at the heart of the Milky Way: 
It seems that our galaxy has structures in the magnetic fields and radiation at it's heart that channel high energy radiation away and into intergalactic space: The Milky Way has 'chimneys' for high energy radiation:
