SpaceX (general discussion)

It seems quite serious situation at SpaceX, Elon Musk since he tweeted NOTHING about issue.

My guess on failure are two:
Either the propellants tanks failed under pressure (SpaceX had issue with that before)
Or the 3D printed dragon Engines have unknown issue, if there were in space and back

What are the chances of Boeing with the CTS-100 Starliner getting the job to launch the first Astronauts to the ISS since the SpaceX anomaly all but delayed the Dragon launch?

Boeing according to what’s been posted on places like NSF have had their own issues.

A side point that’s come up on NSF is that Space X will probably need to prove the lack of commonality with cargo Dragon after this incident.

Here’s what we know, and what we don’t, about the Crew Dragon accident

Further to the above.

At a beginning of a media telecon on the science flying on the next Dragon cargo mission, NASA says the mission is still scheduled for launch April 30, the date reported last week week prior to this weekend’s Crew Dragon incident.

NASA moves ahead with cargo Dragon launch after Crew Dragon anomaly

The fact that NASA is, for now, proceeding with the cargo Dragon mission suggests the problem is isolated to the SuperDraco thrusters, which are not used on the cargo version of Dragon. However, industry sources say that the CRS-17 mission could still be delayed depending on what the ongoing investigation might turn up in the coming days, as well as any concerns raised by the station’s international partners.



SpaceX did, though, file a license application with the Federal Communications Commission April 22 for a Falcon 9 first stage landing on a droneship a short distance offshore for an upcoming launch. Falcon 9 first stages for Dragon cargo missions usually land back at Landing Zone 1, suggesting that the ongoing investigation or cleanup from the Crew Dragon incident makes the zone unavailable for the upcoming launch.

Lest hope that the investigation does not take too long or the scheduled launch date might slip into next year.
 
SpaceX’s Starship, Starhopper prototypes continue slow and steady progress

The last few weeks of SpaceX’s work on Starship and Starhopper prototypes has been marked by less visible progress relative to the past few months. The changes that are visible, however, confirm that its Boca Chica engineers are working around the clock to complete the first orbital Starship prototype.



At the same time, it appears that SpaceX’s South Texas facilities are preparing for a rapid period of expansion and build-up. New work around the ad-hoc Starhopper pad has recently begun, while construction of a second concrete jig for concurrent prototype fabrication and what will likely be a more permanent hangar and control facility are also ramping up. Things have been quiet news-wise for SpaceX’s McGregor and Hawthorne facilities but there is reason to believe that Raptor production and testing is going smoothly.

Exciting times lay ahead ! I really want to see that thing fly.

"The firing was intended to demonstrate integrated systems SuperDraco performance in two times vehicle level vibro-acoustic-like for abort environments," [NASA ASAP chairwoman Patricia Sanders] said. Sanders explained that the test was simulating the Falcon 9 rocket below the spacecraft breaking apart and triggering an abort.

"Firing of 12 service section Dracos were successfully performed," she said, noting that the 12 smaller Draco engines used for in-space maneuvering functioned normally. "Firing of eight SuperDracos resulted in an anomaly," Sanders concluded. This suggests the anomaly occurred during or just after the SuperDraco test. Sanders also noted that SpaceX followed all safety protocols for the test and that no one was injured.

This probably explains why they are letting the Commercial Resupply flight go ahead -- they are confident that the problem is specifically related to SuperDraco, which the cargo Dragons don't have.
 
Seems old suspect show up again at SpaceX
The issue with Super Dracos points to Pressure vessel for Propellants and Helium
Another suspect is the tubing of Super Dracos with propellants tanks.

Narrated in Brazilian but the imagery is nice. All English versions have been pulled. Doesn't seem to be a pay version for sale on Nat Geo.

 
Here's an English version:

If it doesn't load it must be location-blocked and you'll have to use a VPN (works without one in Australia).

SpaceX Crew Dragon spacecraft destroyed in test mishap, company confirms
A senior SpaceX official confirmed Thursday that an "anomaly" during an April 20 ground test destroyed a Crew Dragon spacecraft meant to clear the way for the launch of two astronauts this summer. SpaceX Vice President Hans Koenigsmann added it's not yet clear how long the program will be delayed or even if a piloted mission might get off the ground before the end of the year.
"We're going to learn a lot, and I think this will make the program actually safer at the end of the day," Koenigsmann, SpaceX's vice president of build and reliability, told reporters. "In terms of schedule, finishing the investigation and resolving this anomaly is our prime focus right now. We will see what comes out of it."

SpaceX’s Starhopper gains thruster pods as hop test preparations ramp up

Amid a flurry of new construction at SpaceX’s Boca Chica facilities, technicians have begun to install thruster pods on Starhopper in anticipation of the prototype’s first untethered flights.
Click to expand...

On May 6th and 7th, SpaceX began to install what looked like Falcon ACS pods on Starhopper. Curiously, of the two pairs of thrusters now installed, half appear to be taken directly off of older mothballed Falcon 9 boosters, while the other two seem to have been acquired from a Falcon 9 Block 5 rocket. The latter pods may very well have come from Falcon 9 B1050, the booster that unintentionally landed in the Atlantic Ocean last December.
Click to expand...

Based on the asymmetric location of the first two pod groups, Starhopper’s ACS will probably use a tripod layout. Additionally, the reason for the thruster pairs – versus Falcon 9’s single pods – is likely simple: Starhopper is far heavier than a Falcon booster. To get the same level of control authority, SpaceX is thus pairing pods together to double the functional strength of Starhopper’s ACS.

Crew Dragon parachutes failed in recent test

“The test was not satisfactory,” responded Bill Gerstenmaier, NASA associate administrator for human exploration and operations and one of the witnesses at the hearing. “We did not get the results we wanted, but we learned some information that’s going to affect, potentially, future parachute designs.”



In that test, one of the four parachutes was “proactively failed” to demonstrate the “single-out” capability of the overall system. However, he said, “the three remaining chutes did not operate properly.” That caused a test sled to hit the ground faster than expected, damaging it.



An industry source, speaking on background after the hearing, confirmed the problem with what SpaceX considered an “advanced development test” of the parachute system “specifically designed to measure loads within each parachute canopy.” One of the four chutes was deliberately disabled, but the other three did not open fully.
Click to expand...

SpaceX said that, prior to last month’s test, it had performed five similar “parachute-out” tests where one of the four parachutes deliberately did not open. All of those were completed successfully. The company has performed 19 tests of the parachute system to date with “a number of additional tests” planned before the Demo-2 test flight of the Crew Dragon vehicle, with two NASA astronauts on board.

Elon Musk shows off SpaceX’s 60 internet-beaming satellites packed together for launch

On Saturday, SpaceX CEO Elon Musk revealed the 60 satellites his company will be launching this week — the first batch of thousands of satellites that SpaceX hopes to deploy in the years ahead to provide global internet coverage from space. Musk tweeted a picture of the satellites packed tight together inside the nosecone of the Falcon 9 rocket that will take the spacecraft to orbit.

Reagan Beck @bluemoondance74

SpaceX McGregor has been w/out any window-rattling. When can we expect Raptor SN4 to arrive?



Elon Musk @elonmusk

SN4 is done. Hawthorne is working on SN5 now, but focus is ramping build rate of SN6 through SN10.



Dark Energy @Alejandro_DebH

Any prediction on when you expect to reach the "100 milestone" ie building the SN100 Raptor? I hope it is early next year. You'll need a lot of engines!



Elon Musk @elonmusk

That’s about rightp

No everyone has access to Twitter.

It is the standard rule as per NSF.
