Science Space Exploration megathread - Page 320

**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.

SpaceX is targeting Thursday, January 13 for a Falcon 9 launch of Transporter-3 to orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The 29-minute launch window opens at 10:25 a.m. EST, or 15:25 UTC, and a backup opportunity is available on Friday, January 14 with the same window.

Falcon 9’s first stage booster previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, and five Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station.

Transporter-3 is SpaceX’s third dedicated rideshare mission, and on board this launch are 105 spacecraft (including CubeSats, microsats, PocketQubes, and orbital transfer vehicles).

A live webcast of this mission will begin about 15 minutes prior to liftoff.

Almost finished. I can't believe it's gone so well.

Just in from the @NASAWebb team: All 18 primary mirror segments and the secondary mirror are now fully deployed! Congratulations to the teams that have been working tirelessly since launch to get to this point. Soon, Webb will arrive at its new home, L2!#unfoldtheuniverse pic.twitter.com/QsIyr5AWii — Bill Nelson (@SenBillNelson) January 19, 2022

Out-of-control SpaceX rocket on collision course with moon

Falcon 9 booster, launched from Florida in 2015 to deploy Deep Space Climate Observatory, has followed ‘chaotic’ orbit since and is on a collision course with the moon after spending almost seven years hurtling through space, experts say.

I've always found it kind of crazy that none of the Apollo ascent stages ever crashed down. It seems like they'd eventually get dragged down, but apparently they're all still just kind of floating out there to this day (or at least we've never been able to find any of them).

El scrubbo:

SpaceX is targeting Friday, January 28 for launch of the COSMO-SkyMed Second Generation FM2 mission to low Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 6:11 p.m. EST, or 23:11 UTC.

Fourth time's the charm?

SpaceX is targeting Monday, January 31 for launch of the COSMO-SkyMed Second Generation FM2 mission to low Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 6:11 p.m. EST, or 23:11 UTC.

The Falcon 9 first stage booster supporting this mission previously supported the launch of Arabsat-6A and STP-2. After stage separation, Falcon 9 will return to Earth and land on Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station. One half of the fairings supporting this mission previously supported Transporter-1, Transporter-2, and one Starlink mission, and the other half previously supported SAOCOM 1B, Transporter-2, and one Starlink mission.

A live webcast of this mission will begin about 15 minutes prior to liftoff.
