Science Space Exploration megathread - Page 369

**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.

China won't be headed to space with this particular rocket.

Chinese rocket crashes after accidental launch during ground test

A Chinese rocket crashed after being accidentally launched during a ground test Sunday, its company Space Pioneer said in a statement.

The crash happened when the first stage of the Tianlong-3 rocket detached from its launch pad during a test, due to structural failure. It landed in a hilly area of the city of Gongyi in central China.

“Due to the structural failure of the connection between the rocket body and the test platform, the first-stage rocket was separated from the launch pad,” Space Pioneer, also known as Beijing Tianbing Technology, said.

“After liftoff, the onboard computer was automatically shut down, and the rocket fell into the deep mountains 1.5 kilometers [0.9 miles] southwest of the test platform. The rocket body fell into the mountain and disintegrated.”

There were no injuries as a result of the crash, the company said, as people in the area were evacuated in advance of the rocket test.

Space Pioneer, a leading company in the commercial rocket sphere, specializes in liquid-propellant rockets.

In April 2023, it successfully launched its Tianlong-2 rocket, making the company China’s first commercial launch operator to send a liquid carrier rocket into space and successfully enter orbit, according to state media.

Tianlong-3, the rocket that crashed on Sunday, is a large liquid carrier rocket. It was made to help construct China’s satellite internet network.

The rocket’s product performance is comparable to SpaceX’s Falcon 9, according to Space Pioneer, adding that it will be capable of launching the rocket over 30 times per year after the rocket’s first successful flight.

The accident comes just days after China’s Chang’e-6 lunar module returned to Earth from space, where it collected the first ever samples from the far side of the moon.

The mission was a key milestone in China’s “eternal dream” – as articulated by Chinese leader Xi Jinping – to establish the country as a dominant space power and comes as a number of countries, including the United States, also ramp up their own lunar exploration programs.

"Flight 5 in 4 weeks," Musk said Friday (July 5) via X, the social media platform he owns.

Flight 5 will feature an exciting new twist, if all goes according to plan: SpaceX has said it aims to bring the giant booster back for a pinpoint landing on Starbase's launch mount, an effort that will be aided by the "chopstick" arms of the facility's launch tower.

This bold strategy will increase Starship's flight cadence, allowing the booster to be inspected, refurbished and relaunched more rapidly, Musk has said.

Boeing get them space travelers back yet?

**DaFace** · 07-12-2024, 09:32 AM

Well, SpaceX's success streak ends at 334 launches. That's a crazy good streak, but it still sucks. We'll see how quickly they can move through the investigation and get launching again. It'll almost certainly delay things for a little bit at least.

During tonight’s Falcon 9 launch of Starlink, the second stage engine did not complete its second burn. As a result, the Starlink satellites were deployed into a lower than intended orbit.

SpaceX has made contact with 5 of the satellites so far and is attempting to have them…
