#5185: Sticking the landing, again

And this was less ideal than the last time. "This was a high-velocity mission that SpaceX did not have high hopes of a successful landing for, yet they succeeded anyway."

The biggest problem with recovering a booster is energy. Something coming down from an orbital trajectory has a lot of it, and while the fall isn't a problem, the sudden stop at the end is. Like an egg--only an empty rocket booster is more fragile than an egg is. (A well-designed liquid-fueled rocket booster has as little structure as possible, because structure is weight, and weight is bad.)

That's why the Blue Origin tests weren't as impressive as this. That's a suborbital job; it makes a ballistic arc into space but doesn't have enough kinetic energy to make orbit--and the Falcon does.

..all of which is damned cool.

You will be made to celebrate the delusions of a madman. Bruce Jenner is not a woman. If he were, Sports Illustrated would not even be contemplating this.

If Jeb Bush were the presumptive nominee, he would insist that everyone get behind him and vote for him Or Else. Hypocrisy, of course.

Closed a bunch of tabs because it's Friday night and I have to be at work at 9 AM tomorrow, which leaves me little time for anything that's going to prompt me to bloggerate at length.
