Science Space Exploration megathread - Page 217

**DaFace** · 03:36 PM

Since a number of cool things are happening in space exploration these days, we'll widen the scope of this thread a smidge. Conversation about all things space exploration are welcome, whether it be from NASA, SpaceX, ULA, Blue Origin, or anyone else. Chances are most of the discussion will still be about SpaceX since they love to make things public and fun, but nothing's off limits. I'll eventually get around to modifying the OP to include resources for other companies too, but in the meantime, feel free to post any cool stuff you run across.

Space discussions tend to get a little bogged down in jargon, so here's a list of terms you might encounter. (Others, please let me know of others that should be added.)

ASDS - Autonomous Spaceport Droneship - The "barges" that they sometimes land rockets on.
Dragon - The cone-shaped capsule that sits at the top of the rocket for ISS-bound launches that holds the cargo (or, in the future, humans).
F9 - Falcon 9, the name of the rocket itself.
FH - Falcon Heavy, the three-booster version.
GTO - Geosynchronous Transfer Orbit, a type of orbit that will eventually result in the satellite orbiting the earth as it turns so that it seems to be in the same spot from the ground (such as DirecTV or Dish satellites). These types of launches are particularly challenging because they require a lot of power to get them into the right orbit, leaving very little fuel left for landing.
HIF - Horizontal Integration Facility - the building near the launch pad where they put all of the pieces of the rocket together before rolling it out to the pad.
ISS - The International Space Station
JRTI - Just Read The Instructions, the name of the "barge" that they land on for west-coast launches.
LEO - Low Earth Orbit, a fairly low orbit shared by many satellites and ISS. These launches usually require less power to achieve the proper orbit, so the first stage can often be landed back on land rather than on a drone ship.
LZ1 - Landing Zone 1, basically a big open slab of concrete at Cape Canaveral where the first stage will attempt to land (for some launches).
NET - No Earlier Than, basically the date they're hoping to launch, but rocket launches have a tendency of getting delayed.
OCISLY - Of Course I Still Love You, the name of the "barge" that they land on for east-coast launches.
RTLS - Return to Landing Site, a mission where the first stage comes back and lands at LZ1.
Starship - SpaceX's next-generation rocket (and spacecraft) that will hopefully one day take us to Mars. Starship is the "second stage" that will carry cargo or people, but also refers to the whole system. (It's confusing, but think of it like the Space Shuttle, which was both the shuttle itself and the entire launch system.)
Super Heavy - The giant booster that will carry Starship to space.

Literally the ground floor steps to the future survival of the human race. Oh what a time to be alive.

Agree.

Houston (AFP) - SpaceX's crewed capsule isn't called Dragon for nothing.

The two NASA astronauts brought back to Earth on Sunday said they felt they were inside the belly of a beast as it careened into the atmosphere at 17,500 mph.

"It came alive," said mission commander Bob Behnkhen at a virtual press conference held Tuesday in Houston, Texas.

The thrusters were firing to keep the capsule, called "Endeavour," pointed precisely at its target site off the coast of Pensacola, for the first water landing by a US spaceship since 1975.

"The atmosphere starts to make noise, you can hear that rumble outside the vehicle and as the vehicle tries to control, you feel a little bit of that shimmy in your body," continued the 50-year-old.

"It doesn't sound like a machine, it sounds like an animal coming through the atmosphere with all that all the puffs that are happening from the thrusters and the atmospheric noise," he added.

Not only was ride down deafening, but each time the vessel carried out descent sequences like jettisoning its "trunk" that contained the power system and firing parachutes, it was also bone-jarring.

"Very much like getting hit in the back of the chair with a baseball bat, you know, just a crack," said Behnken, describing the sensation.

Behnken and crewmate Doug Hurley, 53, are best friends in real life and both are married to fellow astronauts.

They were addressing journalists, as tradition dictates, two days after their return from a six-month stay on the International Space Station.

The success of the demonstration mission for SpaceX Crew Dragon, the first crewed US spaceship to achieve orbit since the Space Shuttle era, means it will likely soon be certified for regular service.

The next mission is already planned for September.

"The mission went just like the simulators, from start to finish, all the way there was really no surprises," said Hurley.

Both men are veterans of the Space Shuttle program, which ended in 2011, and they had been training for five years with SpaceX.

Splash down at 15 miles per hour in the Gulf of Mexico felt "pretty firm," said Hurley, but that was expected.

One person who will particularly benefit from Behnken's knowledge: astronaut Megan McArthur, who is slated to make the same voyage in the spring of 2021 on the same spacecraft, and is Behnken's wife.

Just to let you guys know, I'm leaving for a while and maybe forever. Take care of my thread. Go SpaceX.

One of a few threads that keep me coming back here. Sorry to see you go.

You take care of yourself Daface and best of luck. If you don't return, it was great getting to know you.

I'm sorry to hear that, DaFace. Worry not. We'll take care of this thread. God speed and I hope you come back soon.

??? Hope everything's okay. Good luck or good hunting, whichever is appropriate.
