Avartar2go .. these updates you post are awesome. Best thread on the site. Much thanks! I disagree. Info Avatar presents is commonly available elsewhere. To this opinion is added to spark debate.

Speaks volumes about those outlets that the most powerful rocket ever built, on its first flight, performed on or above expectations, the IUS completed its longest ever burn and on so many other ways it, the spacecraft itself has worked like a charm and they bang on about a couple of lift doors?

NASA will host a media briefing at 5pm ET today, to review the Orion lunar close approach & burn. They should have HD video available by then as well, if not sooner. https://www.nasa.gov It's also been announced they have increased the bandwidth available from the Deep Space Network, and may be...Jump to post
Another thing about “escape velocity”. You may want to have an abort capability, using the spacecrafts engine, after TLI. This would limit the amount of energy TLI could provide.
Honestly, I’m not sure if Orion has this capability. Early Apollo lunar missions did however.
The speed at TLI is the escape velocity of the Earth, so around 25,000 mph. After the burn is complete, the vehicle is slowing at less than 1 g (32 ft/s per second) in the radial direction, as it remains within the Earth's gravitational field. But continues to have very high speed in the tangential...Jump to post
As far as outing my friends at NASA, or elsewhere in the industry, there's obviously no way I would ever do that. If you want to call me a liar in the face of that, that's up to you. I would not post what I do here without being reasonably certain. Please read the forum rules. If you cannot / will ...Jump to post

But when I talk to people at NASA about this, they say they have information, but only SpaceX has the legal right to disclose it. They also say they feel the contract is too restrictive on that issue. They aren't allowed to discuss internal debate or disagreement with SpaceX either. So if there are...Jump to post
I'm not a contracts expert, however I am a US gov't contractor so I have some experience. It is my observation that SpaceX has a commercial services contract vs a build, provide design services for, a NASA concept type contract that we all remember from Apollo and Shuttle. As such SpaceX has legitim...Jump to post
Just out of curiosity Avatar2go. Who do you work for? I'm semi-retired, still do some consulting with schools on STEM programs. But I know people who work in the industry, mostly at NASA, but one or two at Blue, Aerojet, Lockheed, Boeing. I try to represent their viewpoint. They are discouraged fro...Jump to post
Then maybe you shouldn't have polluted the thread with your childish, garbage based anti Elon rant. With respect, the discussion began with a shot taken at ULA, about launching a horse into space. It went downhill from there and I played a role in that, no doubt. I gave a paper that established the...Jump to post
Roadster has not been tracked since 2018. It's being tracked well enough to know it's orbit with precision, just like other NEOs. And to make these predictions, which aren't possible otherwise. And when it nears earth, it will be identified and tracked, like everything else. NEOs are not tracked ev...Jump to post
How else would it's location be known, or it's trajectory calculated. It's tracked by NASA as it periodically approaches Earth and Mars. As of Monday, the roadster was about 234 million miles from Earth and about 200 million miles from Mars, passing through a no-man’s land of outer space, according...Jump to post
The odds of collision with Earth are similar to other near earth objects (NEOs) with equivalent mass. Hence is now being tracked as a NEO. https://arxiv.org/pdf/1802.04718 Maybe I missed it, however I see nothing here that suggests Musks Roadster is being tracked as a NEO, and it appears to be unli...Jump to post
So if no payload will Bruno attempt to out Musk Musk? What might he launch? A horse would be cruel….. No, no stupid publicity stunts that pollute the solar system with space junk, which doesn't even follow the intended trajectory. That's entirely a Musk brand. ULA would use a dummy payload that wou...Jump to post
ULA has announced the first Vulcan launch has been delayed to Q1 2023, at the request of the payload vendor Astrobiotics. But if not launched by then, Tory Bruno has said it will launch without payload, in order to meet the terms of their government contract. The first launch-ready BE-4 engine is n...Jump to post
Self-understood. But. It takes two to tango. Beyond all niceties and fluff, USAF can take Boeing to the letter of the contract, that's what I am saying. These things are not happening unilaterally, correct? So, from purely legalistic point of view, if there is a unilateral cancellation on the contr...Jump to post
Boeing is not going to cancel the VC-25B program. They took a risk on the fixed cost contract, thinking they could get it done. Then ran into contractor and labor issues, that in return resulted in extensive redesign. So now they have to eat the cost, and that's that. Calhoun said as much in the ea...Jump to post
At what point would Boeing consider scrapping the program? When the cost overruns exceed the PR and prestige value of the program. What, outside of bankruptcy filing, would allow a defense contractor, to wiggle out from a DoD order, duly signed and paid? USAF is an entirely different matter. Questi...Jump to post

Best way to defend against a cheap but effective weapon is an even cheaper defense.

Mr & Mrs Tito announce plans for around the moon trip on Starship: https://youtu.be/akRWCov_LSo
You may recall Tito was one of the first space tourists some 20 years ago on Soyuz.
Also SpaceX and NASA have waived off all Crew 4 undock windows for today due to landing site weather.
From the briefing, NASA clarified that the mission requirement was 73 seconds, but as they closed on the asteroid, their models predicted from a few seconds to multiple tens of seconds. So they feel like they got into the higher range at 32 seconds. Lots of observations and data yet to come. It wil...Jump to post

A good review. Every now and again upper ranks get a screw loose, and proceed with this sort of thing. US Navy has to blame someone I guess. Systemic failures on the part of the Navy were certainly responsible for the loss of the ship. You’d think a fire in the shipyard would have numerous firefigh...Jump to post
An altitude boost mission seems generally possible, but I wonder about an actual servicing mission on any of the capsules (or even Dream Chaser) since the Shuttle provided a large "platform" to anchor Hubble to during the work and I am not sure how suitable any of the current crewed or ca...Jump to post
