    As well they should be.
    Scott Manley points out that these failures weren't in software for some obscure function, but features depended upon for every flight.

    I watched Scott's video on this too and I found that really remarkable. None of the software failures were some weird combination of unforeseen conditions, nor some hardware failure, they were all problems in the standard sequence of programming steps that were planned for this mission. These are problems that should have been found on the first run through of the software.

    We've had one* of these at ESA where apparently ATV couldn't see the difference between docking to ISS head first or tail first, but at least that was discovered during an early simulation as it should be.


    (*) it's programming, I'm sure they had countless of these oopsies, just like any other space agency or breathing creature remotely involved with programming. The key is to catch these big errors before shooting things into space. There's still plenty of subtle stuff in code with less subtle outcome to solve after that.

    Starliner presser today - this sums it up

    Tim Fernholz ✓ @timfernholz
    Boeing VP John Mulholland keeps getting asked why and how the company made Starliner test decisions that allowed multiple mistakes to slip through, and won't answer the question.

    https://twitter.com/timfernholz/stat...36763277758464

    Marina Koren ✔ @marinakoren
    Replying to @marinakoren
    Mulholland tells me that after audit of the flight software is done, they'll be able to say exactly how many issues they had (so far, there's a few). Says the NASA astronauts assigned to the first crewed mission are "supportive," have visited Boeing since the botched mission
    ||
    Wow: At beginning of presser, Mulholland said this Orlando Sentinel report "mischaracterized" Boeing's testing. But later, when pressed, he confirmed what @ChabeliH reported. Boeing didn't run this end-to-end test, but it will do it now, Mulholland says

    https://www.orlandosentinel.com/spac...ahu-story.html

    Boeing didn’t perform full end-to-end test of its astronaut capsule before troubled mission,...

    A panel learned early this month that Boeing did not perform a full, end-to-end integrated test of Starliner in a Systems Integration Lab with ULA’s Atlas V rocket. It’s the kind of test that could...

    "NASA investigation finds 61 corrective actions for Boeing after failed Starliner spacecraft mission"

    https://www.cnbc.com/2020/03/06/nasa...pacecraft.html

    The National Aeronautics and Space Administration’s investigation into Boeing’s failed December spaceflight came up with a long list of corrections needed before the company flies again.

    Boeing said Friday that the investigation found about 61 “corrective actions” for the company’s Starliner spacecraft, which it has been developing to fly NASA astronauts. NASA associate administrator Doug Loverro told reporters on a conference call that he expects it “will take several months” for Boeing to work through the list.

    “This was a close call. We could have lost a spacecraft twice during this mission,” Loverro said.

    The single most concerning thing here is the degree of involvement Boeing has with the SLS. After the 737 MAX, KC-46 and Starliner issues its hard to have a great deal of confidence. A Starliner type glitch on the SLS test and you could be looking at years of delay, not months.

    Starliner is, being kind and in military-speak, a Charlie Foxtrot. If rumors are true, it gets worse.

    We know their original 2010 CCDev contract had risk reduction funding foe the circumferential bolted seam holding together the two clamshell domes. We also know there was problem with the thermal vacuum test 2 years ago. In the recent teleconference there was mention of a cold spot in the capsule.

    My spider-sense is tingling like a 480 volt line hit it .

    Yeah, I can see this winding up as 'hangar queen', and I wouldn't be suprised that if Dreamchaser nails its CRS-2 missions the manned version gets a crew contract, while some excuse is found for Boeing to bow out. Article below discusses the cargo Dreamchaser, the controversy over the award of the contract to Boeing/Starliner and that work on the manned version is still ongoing despite getting no funding:

    We have progress. SpaceX aiming for a manned flight in May

    https://www.spacedaily.com/reports/S...orida_999.html

    SpaceX president Gwynne Shotwell said Tuesday the company is "gunning" for a May launch of astronauts from Florida, while NASA said only that it hopes for a launch sometime in the second quarter.

    SpaceX is poised to be the first private company to fly NASA astronauts. The company's successful in-flight test in January showed that the capsule could carry people to safety in an emergency.

    "We're gunning for May. We have work to do, NASA has work to do," Shotwell said at the Satellite 2020 conference in Washington, D.C., according to CNBC.

    The flight would carry astronauts Bob Behnken and Doug Hurley to the International Space Station. The space station has only been accessible to American astronauts through the purchase of seats on Russian capsules since the last shuttle launch in 2011.

    Interesting:

    Responding to a question on the matter by Reuters space reporter Joey Roulette, Boeing Space confirmed that "#Starliner uses a Power Converter Unit provided by Zao Orbita in Voronezh, Russia."

    I worked for Boeing Commercial Airplanes until 10 years ago. If there was any way they could have work done by someone other than regular Boeing employees, that was how they did it. Employees were first, last, and only an expense. Our skills and experience were of little or no value.

    If that sounds like I'm bitter, you're right.

    Crew*Dragon DM-2 to ISS: late May, 2020

    https://www.nasa.gov/press-release/n...ica-since-2011

    March 18, 2020

    MEDIA ADVISORY M20-041

    NASA, SpaceX Invite Media to First Crew Launch to Station from America Since 2011

    *
    Media accreditation is open for NASA’s SpaceX Demo-2 flight test, which will send two astronauts to the International Space Station as part of the agency’s Commercial Crew Program. This mission will be the return of human spaceflight launch capabilities to the United States and the first launch of American astronauts aboard an American rocket and spacecraft since the final space shuttle mission on July 8, 2011.

    SpaceX’s Falcon 9 rocket will launch Crew Dragon, with NASA astronauts Bob Behnken and Doug Hurley aboard the spacecraft, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. NASA and SpaceX are currently targeting no earlier than mid-to-late May for launch.

    This second demonstration mission of the Crew Dragon spacecraft is another end-to-end flight test of SpaceX’s human spaceflight system, which will include launch, docking, splashdown and recovery operations. It is the final flight test of the system before SpaceX is certified to carry out operational crew flights to and from the space station for NASA.

    Media accreditations deadlines are as follows:

    ·* * * International media without U.S. citizenship must apply by 4 p.m. EDT Friday, April 17.
    ·* * * U.S. media must apply by 4 p.m. Friday, April 24.
    All accreditation requests should be submitted online at:
    https://media.ksc.nasa.gov

    NASA is proactively monitoring the coronavirus (COVID-19) situation as it evolves. The agency will continue to follow guidance from the Centers for Disease Control and Prevention and the agency’s chief health and medical officer and communicate any updates that may impact mission planning or media access, as they become available.

    For questions about accreditation, please email*

    ksc-media-accreditat@mail.nasa.gov.*

    For other questions, contact Kennedy’s newsroom at 321-867-2468.

    Reporters with special logistics requests for Kennedy, such as space for satellite trucks, trailers, tents, electrical connections or work spaces, must contact Tiffany Fairley at*

    tiffany.l.fairley@nasa.gov*by Friday, April 24.

    NASA’s Commercial Crew Program is working with the American aerospace industry through a public-private partnership to launch astronauts on American rockets and spacecraft from American soil. The goal of the program is to provide safe, reliable, and cost-effective transportation to and from the space station, which will allow for additional research time and will increase the opportunity for discovery aboard humanity’s testbed for exploration. The space station remains the springboard to NASA's next great leap in space exploration, including future missions to the Moon and eventually to Mars.

    NASA astronauts Doug Hurley and Bob Behnken familiarize themselves with SpaceX’s Crew Dragon, the spacecraft that will transport them to the International Space Station as part of NASA’s Commercial Crew Program. Their upcoming flight test is known as Demo-2, short for Demonstration Mission 2. The Crew Dragon will launch on SpaceX’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

    NASA ASAP report, their safety panel ...

    https://spacenews.com/safety-panel-c...t-is-feasible/

    SpaceX Crew Dragon

    NASA ASAP says there are a few Crew Dragon DM-2 issues to resolve, but May is possible.

    Boeing Starliner

    Sounds like Starliner may not fly astronauts in 2021.

    “Much remains to be resolved before they will be expected to be certified for human spaceflight,” Sanders said of Boeing, saying that work goes beyond a second OFT mission.

    That second flight, she said, “is not sufficient to address the concerns that have arisen following the OFT, and we continue to strongly advise NASA to ensure that the underlying technical and organization or cultural shortcomings uncovered during the investigation of the mishap and subsequent reviews are fully addressed and mitigated before any attempt to launch astronauts on the vehicle.

    SpaceX Crew Dragon DM-2 is on for May 27. Webcast & cable
    programming begins at 1215 Eastern on NASA TV.

    Neat video on Twitter

    NASA ✔ @NASA
    Together with @SpaceX, we will return human spaceflight to American soil after nearly a decade. May 27 is not only a big day for our teams – it’s a big day for our country.

    What does our @Commercial_Crew launch mean to YOU? Share using #LaunchAmerica: https://go.nasa.gov/2AeqVnF

    SpaceX has a docking simulator that’s supposed to have the same controls as the real Dragon capsule. Don’t expect a lot of excitement, and I probably use more fuel than they would, as I approach fairly quickly, but I had little trouble docking. Good to know if ever in an emergency situation .

    In terms of the Orion capsule—I read (from space daily) that part of the splashdown recovery is called...mmph...is called [cough]...
    “Sasquatch”

    The jokes—they write themselves.

    I’m surprised Coast-to-Coast hasn’t done a bit on this.

    Really, NASA? REALLY?

    You know, I made myself look really foolish over the years trying to defend Old Space—and you “steely eyed” missile-men go and pull this stunt?

    I give up
