ULA's been losing money for years. THIS year they cut muscle instead of fat---laying off hundreds of engineers and operations staff.

It got a LOT worse after SpaceX landed on a boat.ULA's Atlas-V launches usually cost somewhere between 130 million up to 500 million (and even over a billion) to boost a satellite into orbit. Once Falcon Heavy kicks in this year they'll be outclassed on cost, launch frequency AND weight.
Fuck ULA. Only retards can fuckup a monopoly, good riddance.

To be fair ULA was mostly a caretaker organization meant to sustain the Atlas-V and Boeing Delta-IV's that they've been selling to the market for FIVE FUCKING DECADES. They didn't have the mandate nor the resources to actually create new rockets or anything.

Before even SpaceX showed up they were losing business to Airbus' Ariane-5 booster. Yeah. Fucking Airbus.

Pretty great vid on a problem I didn't know existed. Love how they solved it with Tinkertoys.

Yeah, need to load that video up in the cardboard viewer when I get a chance. Awesome.

That's prolly the best way to experience it yeah. It's impossible to get the scope and scale of the thing from the aerial views.

The reusable portion of the booster is over 160 feet tall---but you don't get the scope of seeing a fucking 14-story building riding on a 100-foot column of fire and land so smoothly it can't bounce more than a few inches.

Does the barge have any autonomous way of securing the rocket when it lands? Seems like a decent sized wave or wind could blow that thing over.

Nah. They must've just designed it with a deep enough draft and ballasting to be stable enough for that load and those seas. During the landing video for CRS-8 they said they were looking at 8-foot chop but it was well within their designed parameters.

If you look at the video at high res you can see how the waves were chopping way higher on the barge's bow than in the previous attempted barge landing in 2015.

Apparently they designed the barges to shrug off exploding rockets too, since the barge that CRS-7 blew up on is slated for to be up for the next launch:



Most ppl only saw the barge-camera view of the explosion, but that drone aerial view is pretty cool since you can see the thrusters vectoring heavily to correct the pitch of the rocket before landing. SpaceX said that it wasn't the momentum of the rocket's overcorrection that tipped it over---it was actually a faulty lock on one of the four landing legs that made the rocket fall, so they should've actually stuck that landing back in June of last year.

That correction is amazing.

I love that website for some reason.

Capabilities & Services

SpaceX offers open and fixed pricing for its Falcon 9 and Falcon Heavy launch services. Modest discounts are available, for contractually committed, multi-launch purchases.SpaceX can also offer crew transportation services to commercial customers seeking to transport astronauts to alternate LEO destinations.

Once the rocket has landed and defused, they fully Weld on these special feet over the landing struts for it's journey back to dry land.

Rad little story. Mostly the fact that Kepler will be observing this system and its close enough that the JWST should be pointed that way assuming it works like it should. 40 Light years isn't that far in a galactic sense. Just a suburb.
Its still so far that it doesn't matter unless we develop very radical propulsion tech. 40 light years might as well be another universe with our tech.

Yeah pretty much. whats our top speed right now? .01% of light speed?

The two inner worlds, depending on atmosphere and ground surface will be from above boiling point to over tropical. The outer one has so much unknown that it could be barely habitable to frozen ball.

But the main point is that red dwarf stars are the most abundant in the galaxy, long lived, and since they seem to be able to form "nice" planets, they'd be the best candidates for life due to sheer amount of planets.
