PSA: SpaceX Starship's 7th Integrated Test Flight scheduled for Thursday January 16th at 4:00PM CST

Continues…



“Achieving materially positive payload margin to a useful orbit with a fully & rapidly reusable rocket has eluded prior attempts. Many have tried to embark upon this path only to give up when it became clear that their design would have negative or negligible payload margin.

This is an extremely difficult problem to solve, given the strong gravity of Earth, whereas it is easy on Mars and trivial on the Moon. In the early years of SpaceX, I was not sure that success was even in the set of possible outcomes!

Fortunately, it just barely is, but requires doing unusual things like shifting the mass needed for final velocity attenuation and post-landing stabilization of the rocket (so it doesn’t tip over in wind) to the ground, rather than carrying heavy landing gear on both stages.”
This is great and all but it's going to take some time for people to gain confidence that this can be done safely, particularly for manned flights. Would you want to fly on a rocket that was doing it's 4th trip of the day and only had a few hours between launches? What kind of safety checks are there? I'm not suggesting it's not done properly or safely, but it's going to take many, many rapid flights with zero mishaps before people start to trust this thing.
 
Beaten to low earth orbit by bezos on his first try. Sad.

What?

The Falcon 9 v1. 0 rocket successfully reached orbit on its first attempt on 4 June 2010. Its third flight, COTS Demo Flight 2, launched on 22 May 2012 and launched the first commercial spacecraft to reach and dock with the International Space Station (ISS). The vehicle was upgraded to Falcon 9 v1.

Whose ship is in orbit and whose is scattered across the ocean?
Derp.

As of March 10, 2024 and based on Celestrak data processed through the NCAT4 analysis toolkit, 59% of all active satellites belong to SpaceX. Active satellite include all satellites LEO, MEO and GEO orbits used for communications, navigation, earth observation, weather and science.
 
Don't you just love the difference between the PR focused coverage these days vs the sober, fact-laden coverage back when NASA was running things?

Yeah, me neither.

At the end of this video, when they acknowledged the failure of the payload part, their voices are so phony and cheerful as they reassure us that everything was basically a huge success.

Made me think of

The operation was a success but the patient died.​
Other than that, Mrs Lincoln, how did you like the play?​
