It will be sad and a bad look at our future as a society if this doesn't become the highest grossing Documentary of All-Time. IMO

NASA should just get out of the way of SpaceX and let them handle rocket building.


NASA reassessing date for first SLS launch

-------------------------------------------------------
NASA reassessing date for first SLS launch

WASHINGTON — The director of NASA’s Marshall Space Flight Center said March 5 that the agency is “reassessing” the 2020 launch date for the first flight of its Space Launch System, suggesting that the mission may face further delays.

During a question-and-answer session at a Space Transportation Association luncheon here, Jody Singer said the launch readiness date for Exploration Mission (EM) 1 is still in 2020, but did not give a more precise estimate of the date even as NASA reviews possible changes to it.

“We do know that we are reassessing those dates to see if that date will work, based on making sure we have the vehicle ready, and ready to go fly safely,” she said. “We are assessing that date. Our launch readiness date is still 2020, and we’re doing everything within our power to make sure that we support that.”

Singer didn’t identify the specific issues with EM-1 that prompted the reassessment, but NASA officials have previously said that the core stage of the SLS, along with the European-built service module for the Orion spacecraft that SLS will launch, were the items on the critical path for the mission.

A report in October 2018 by NASA’s Office of Inspector General criticized both NASA and Boeing, the prime contractor for the SLS core stage, for problems with that element. At that time, the office concluded that EM-1 would not be ready to fly in the first half of 2020, as planned by the agency at that time.

Singer, a veteran engineer and manager who became director of NASA Marshall in September 2018, acknowledged issues in the development of SLS in general, whose first launch has slipped from 2017 to at least 2020 over the course of its development. “We are working hard to build SLS and, yes, we’re overcoming challenges,” she said.

Other elements of the SLS are largely complete, she said, including its two five-segment solid rocket boosters, upper stage and adapters. “The SLS vehicle is almost complete. It’s in its final outfitting,” she said, with the exception of the core stage.

Structural test articles of liquid hydrogen and liquid oxygen tanks will be tested in the coming months at Marshall, she said, while the core stage flight hardware is assembled at the Michoud Assembly Facility in New Orleans. That core stage should be and transferred to the Stennis Space Center in Mississippi for so-called “green run” testing, when its four RS-25 engines are fired on a test stand, “in the late part of this year or early part of next year.”

Another issue with the SLS is development of the Exploration Upper Stage (EUS) that will be used on the future Block 1B version of the rocket. While NASA planned to shift to the Block 1B on the second SLS flight, the agency instead expects to fly the original Block 1 version, with its Interim Cryogenic Propulsion Stage, for at least three missions.

Boeing said last October that it had slowed down work on the EUS at the request of NASA, and was looking at ways to refine the stage’s design in order to increase its performance. That would enable it to increase the amount of co-manifested payloads, such as elements of NASA’s planned lunar Gateway, it could carry on missions that also include the Orion spacecraft.

Singer said that NASA had made “significant steps” on the design of the stage, with a critical design review scheduled for late this year. “A critical part of designing the upper stage is making sure we understand the mission and the components that we need to take and where we need to go,” she said. “We are making definite forward progress on the upper stage.”

The report accompanying the final fiscal year 2019 appropriations bill funding NASA directed that at least $150 million of the $2.15 billion provided for SLS be directed to work on the EUS. It also stated that the EUS, along with a second mobile launch platform built specifically for the Block 1B version of SLS, be ready for flight no later than 2024.

Funding has, in general, not been an obstacle for development of the SLS. A major factor in that has been the support of Sen. Richard Shelby (R-Ala.), chairman of the Senate Appropriations Committee. Shelby appeared briefly at the luncheon to introduce Singer.

“As chairman of the appropriations committee, I have more than a passing interest in what NASA does. And I have a little parochial interest, too, in what they do in Huntsville, Alabama,” where Marshall is based, he said. “Jody, you keep doing what you’re doing. We’ll keep funding you.”

I am wondering if NASA just needs to be the regulators of space, and maybe astronaut trainers. or at least do the testing or whatever.

With the way companies are implementing new ideas (Bigelow Aerospace for an example other than SpaceX) it does make one wonder if the time of NASA and other national level space programs are coming to a sunset and will be put more into the roles you described rather than manned exploration.

A mission to Mars is still going to be a huge financial undertaking, but so far some private companies are doing pretty good managing costs than others.

Internally, NASA believes Boeing ahead of SpaceX in commercial crew

That article was from last July however IMO, There are a lot of folks high up at NASA that don't like SpaceX (i.e. Elon Musk) for being so successful as an upstart being able to steal top talent, etc..

Boeing is part of the old guard supplier to NASA the Starliner is very old school looking more function over aesthetics & comfort that the SpaceX crew Dragon has. (There are several videos online comparing the two)

It will be interesting if the Dragon successfully undocks and has a clean reentry and splash down on Friday. How that will effect the Demo 2 (crewed) mission proposed for July. Reading between the lines of watching the mission briefing vids that there is already things that NASA wants SpaceX to change between this mission and that one.

Yeah, I saw it was dated when I posted it, but I thought it funny that Boeing was "ahead" of SpaceX considering what just happened.
