A few random and/or cool things happened this week that I couldn't find where to post appropriately, so my intent on this thread is for those items that aren't "WTF," as that, to me, has a negative to shocking connotation and the items here are not that. It would be great if they were all uplifting, but one of mine is not going to be, unfortunately.
Mods, apologies if these have places to be sorted and I missed it.
1. NASA flew a freakin' helicopter on Mars twice over the last week.
2. NASA via SpaceX flew a previously-owned rocket and ship to the ISS taking a four-man crew including the wife of the commander of the first SpaceX launch.
3. An Indonesian submarine sank on Thursday and is still unfound. Although likely having gone down below crush depth already, the crew runs out of oxygen tomorrow if they haven't. One of the top three ways I wouldn't want to die.
