Science Space Exploration megathread - Page 163

**DaFace** · 07:17 AM

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.

Officials blamed the failure of the Starliner capsule on a possible software problem that made the autonomously commanded spacecraft misperceive where it was in the flight and miss the moment when thrusters were supposed to fire and push the craft into the correct orbit.

Well, at least they didn't kill a bunch of people this time...

Agreed. But like they said at the press conference, a lot went right too.

**DaFace** · 12-22-2019, 11:55 AM

Looks like they got it on the ground without incident, so that's promising. Hopefully they can get their software figured out and be flying again soon.

Today, @BoeingSpace’s #Starliner spacecraft safely returned to Earth with a bullseye landing. Although the spacecraft didn’t reach its intended orbit and dock to the @Space_Station, it did complete many test objectives for our @Commercial_Crew program: https://t.co/1jWkMI5oA6 pic.twitter.com/SEm2iKUviR

SpaceX is closing out the year with an achievement that should help it keep on track to fly astronauts on board one of its spacecraft next year. The Elon Musk-led space company finished its 10th successful parachute system test in a row yesterday, an important safety system milestone that should be a good indication that the latest design is just about ready for use with astronauts on board.

The parachute system is what’s used to slow the descent of SpaceX’s Crew Dragon commercial astronaut spacecraft on its return trip to Earth, once it enters the atmosphere. The current design is the third major iteration of SpaceX’s parachute for Crew Dragon, featuring upgraded materials and improved stitching for the best possible reliability and durability during flight.

Earlier this year, at an event hosted at SpaceX HQ in Hawthorne, California, Musk told media and fans in attendance that the Mark 3 parachute system would need at least 10 successful tests in a row before the company would feel confident about using it for actual crewed flights. At the time, NASA Administrator Jim Bridenstine also said he believed SpaceX could achieve all 10 before the year was out, and now it has indeed hit that mark.

Currently, SpaceX plans to fly its next major step towards crewed flight on January 11: That’s the current target for its ‘in-flight abort test,’ a required launch that will test the emergency safeguard system that can be triggered mid-launch to carry the crew away from the launch vehicle and to safety in case of anything going wrong that might potentially put them in danger.

Cool little summary video of all that NASA is up to next year. It's easy to overlook how much stuff they're working on all the time.

Did they EVER release the findings of the probe that was sent into Jupiter’s atmosphere a couple years ago?

I sure can’t recall seeing anything about it

unlurking · 01-06-2020, 04:03 PM

Do you mean Galileo from '95?

https://solarsystem.nasa.gov/missions/galileo/in-depth/

Juno doesn't have any descent probes that I know of?

No this was much more recent, like 2017-2018

Are you sure you aren't thinking of Cassini (which was Saturn)?
