This week’s round of space and science news is again a collection of articles posted in my Space & Astronomy Collection on Google+ and in the WSH Crew Community, plus a couple of additional ones that caught my attention. For the third week in a row, SpaceX takes the headlines, this time with another successful satellite launch and an even more difficult booster landing on sea. But that was not all SpaceX was up to this week, because there was also a surprising new price chart, superhero spacesuits and some speculation about the Falcon Heavy, so the first four headlines belong to them. Of course there were some other interesting news this week too, so here’s my very personal and subjective selection.
