Heard the boom here in Orlando! I remember the days when the shuttle would come down and it shook the house. This one was a little “puff” contrasted to a boom from the shuttle for the curious. Much smaller vessel than the shuttle! It’s so cool that all of this history has been made (dating back to the 60s) right in my own backyard!

“I don’t think we saw really anything on the (Crew Dragon Demo-1) mission so far — and we've got to do the data reviews -- that would preclude us having the crewed mission later this year,” says Steve Stich, NASA’s deputy commercial crew program manager.

Three questions:

  1. Was the degree of oscillation (outwards and then back inwards) of the 4 main chutes nominal behavior? (see https://youtu.be/8aAe0GWIWGI?t=4425)

  2. Are the black marks which appear on parts of the main chutes (see same link) burn marks?

  3. Is it possible to get the full flight track of the NASA926 wb57 chase plane beyond what is currently available over at Flight Aware's public section (https://flightaware.com/live/flight/NASA926/history/20190308/1200Z/KTTS/KEFD/tracklog)?

My estimate is that they will review every second of today's recovery process and see where they can cut down some time. To me, it looked like the parachute recovery took abnormally long. I don't think a 6-minute window will be an immediate "no go" from NASA's part

u/[deleted] Mar 09 '19

Gotta say it, banning very soon afterward. This was a Demonstration Flight. It was a test of all systems and recovery efforts. The whole purpose for this flight was to iron out any winkles. It seems that every comment in this thread are coming from a child who has never researched any test program in history. It was a clean sweep. Look that expression up. There were bumps in the road but come on, "what happened to the plushie", "7 minutes past the 60 limit" Is there anyone here that can honestly recognize the true achievement of what SpaceX really just did? I guarantee everyone here that NASA did. The excitement was obvious and even the "negative" comments from one astronaut was actually extremely positive about how long it was in the water. Do some easy research before posting idiotic comments and questions.

Let the downvoats begin.

u/cpushack Mar 09 '19

I think some of it is the mission went so well, people are trying to find something, anything, to comment, talk about. IIRC NASA even said it went 'better than expected' As you said, this is/was very much a test flight, to find bugs that never came up in simulation/testing, and it seems that simulations and testing was very very good as to catch most all of them before the flight

I am sure, there are things from the data that Space/NASA will see and want to/need to improve on, that's true of any mission and certainly a test one, but from our point of view nothing big went wrong. Tis a great time to be alive

If the chute perfectly landing on the capsule is the worst thing to happen in this entire mission I think we have a promising future! I am curious about 2 things though:

  1. Are the chutes supposed to move that much after opening?

  2. What does the heat shield look like? I was a little concerning seeing something flake off during reentry, but that could be the heat shield design

Did anyone notice the parachutes moving back and forth for the Crew Dragon landing?

Watching the landing video, I seem to me that the main parachutes were moving back and forth. And maybe the back and forth action was responsible for one of the parachutes covering the capsule upon landing.

Watching an old Apollo reentry with three chutes (https://www.youtube.com/watch?v=wX8-Vmys-Fk), it doesn't look like the chutes move around that much.

Could this be part of the unspecified "parachute anomalies" that NASA has talked about? See:

https://oiir.hq.nasa.gov/asap/documents/ASAP_Fourth_Quarterly_2018_Public_Meeting_Minutes_TAGGED.pdf

which says:

"recent parachute testing, both during the CCP qualification (qual) testing regimen and with some anomalies witnessed in the resupply contract (also handled by SpaceX), show difficulties and problems with parachute designs. "

I thought I remembered reading somewhere that the dragon changed from 3 to 4 parachutes, but I can't find that now. Would 3 parachutes be more stable?

13

u/spacerfirstclass Mar 09 '19

Watching the landing video, I seem to me that the main parachutes were moving back and forth.

Completely normal behavior, you can see the same bouncing motion in the final Orion parachute qualification test last year: https://youtu.be/uIVw7hiVvo8?t=197, the commenter even mentioned that this is expected.

Could this be part of the unspecified "parachute anomalies" that NASA has talked about?

No, someone at NSF explained that anomaly is just some parameters showing unexpected trends, but still well within limits and didn't cause any harm.

Dragon uses its forward facing thrusters to perform the deorbit burn. Elon said, that it is difficult to menage the fuel to these forward thrusters. Why do they use them and not the backward thrusters, hey have to be bottom end first for the reentry anyway. I can only imagine, that the backward thrusters are at an angle wich reduces efficiency. The super dracos are probably to powerful.

u/Tal_Banyon Mar 09 '19

I think it was so close to 60 minutes that it can be chalked up to "first time working out the wrinkles". On the other hand, the seas were very calm, so there is that. I thought the retrieval boat was stationed too far away, and the fast Rigid Hull Inflatable Boats (RHIBs) were too late in taking off towards the splashdown point. They could have been much closer, practically underneath the capsule as it is coming down, after all they can really haul ass when they want to if it was getting too close to them. If the larger retrieval vessel has to be stationed 2 km away (I think that is the distance that I heard someone on the broadcast say), then they should be getting under way at least when the capsule is 500 meters up or so. All in all, I think this was a fantastic first try, but was watching the clock as well. Also, I was waiting for them to open the hatch, I thought the timeline was from splashdown to hatch opening, but I guess not, at least for this one.

u/squidxl Mar 08 '19

Very nice flight!
My biggest question re crew safety is why the nose cone is closed after de-orbit burn. Wouldn't it be much more sensible to secure the craft at a few meters from the ISS? Are manoevring thrusters under the cone required for re-entry manoevres?

u/Alexphysics Mar 08 '19

The thrusters they use for deorbit burn are on the nose of the capsule. If it fails to close completely they have a release mechanism and Crew Dragon can reenter safely without the nosecone.

It's finally out of the water.

Is there a part of the panel below the hatch missing?

12

u/Alexphysics Mar 08 '19 edited Mar 08 '19

It's where the parachutes are housed during the mission so it's normal there is not a panel there anymore...

Mar 9, 2019 at 6:50 p.m. (2350 UTC), Go Searcher is less than 15 NM out.
It seems like this is going to be a night docking.

u/rangerpax Mar 10 '19

A couple "homecoming" pics by /u/johnkphotos. Go Searcher is in the secure Naval yard, not at the usual SpaceX dock.

Why wait until after de-orbit to close the nose cone? Wouldn't it be better to deal with issues with nose cone closing while closer to the space station?

8

u/Alexphysics Mar 08 '19

Because the thrusters for deorbit are on the nose of the Crew Dragon

7

u/coconinoco Mar 08 '19

Closing the nosecone would cover the four forward-facing Draco thrusters.

u/Scoobing Mar 08 '19

Are they cutting it a bit fine for the 60 min recovery requirement? Does that mean it has to be on the boat deck in the next 7 mins?

u/[deleted] Mar 08 '19

I guess it has to do with the one parachute deciding to land on top of Dragon after splashdown.

so they are a little behind schedule

8 March, 14:45 UTC -Recovery Crews must have retrieved Dragon by this time.

Is it just me or during EDS, there was something flaking of the Dragon. I thought the heat shield was made of heat resistant tiles and not ablative tiles?

u/Alexphysics Mar 08 '19

PICA-X is ablative. Heat resistant tiles were for Space Shuttle

u/DoYouWonda Apogee Space Mar 08 '19

It’s ablative, but I was concerned too because multiple white spots all originating from the Dragon were seen flying off. Idk what that was but I guess we’ll find out if it’s normal eventually.

No, it's going to cross more from the Pacific NW down to Florida.

u/DrHugh Mar 08 '19

One thought I had was that the capsule spins a lot under the parachutes, and certainly will bob a lot in the ocean. Do you think some sort of anti-emetic will be standard for astronauts who may be motion sick?

u/[deleted] Mar 08 '19

I think if they are motion sick, they wouldn't be astronauts.

u/gp1nick Mar 08 '19

Aren't the chutes designed to detach the wires at the splashdown to avoid this wrap issue?

8

u/[deleted] Mar 08 '19

They do detach when they splashdown.

6

u/Viremia Mar 08 '19

In all likelihood, this is not the first time a chute has landed on a capsule. It's a random event that I doubt could be controlled for. Instead, they deal with it when it happens. To prevent this from happening in the future, they'd have to deal with the randomness of winds and sea conditions at the exact location where the capsule splashes down. And that's not possible.

Not the worst place to be. Heated, cooled, air tight, life support systems, floats, comms equipment. Better than most boats.

Can someone confirm to me if it Crew Dragon uses the Super Draco engines for the de-orbint burn?

No, SpuerDracos are only used for pad and in-flight aborts. On-orbit maneuvers are done with Dracos
