What keeps everyone safe when rockets fail? Why did the failed Falcon 9 rocket land in the ocean?

  • SpaceX experienced their first landing failure of a Falcon 9 since 2016! So what went wrong? What kept everyone safe? Is there a big risk of a failed rocket landing on people?
    Today we'll mostly be looking at the CRS-16 landing failure and using it as an example as what systems are on board, what programming is used and how the flight termination system works to keep us on the ground safe.
    We'll dive into the details of its landing sequence by looking at it's exact trajectory using flightclub.io and I'll be explaining what exactly happened using Kerbal Space Program to simulate the failed grid fins.

    I was soooo impressed with what that machine did. It fell from space, had the fin lock up but still managed just before touchdown to stop its rotation, straighten itself out and if there had been solid ground under it I think it might have landed. Those legs came down and it tried it's best to stay up, even on the water! I felt bad for it. They have got to get an "A" for effort and engineering.
    OK. I guess all you guys nit picking my comment work for SpaceX as engineers who are saying it wouldn't have landed. That wasn't my point. Did you see that thing standing straight up in the water?? It was a relatively controlled landing by a crippled vehicle that fell from space! I'm no less impressed. It was an awesome effort by man/woman and machine! Well done.

      Hey tim. In one of the debriefing where elon said that Block 5 is now forzen for certification, he also said that non significant changes are allowed. With the addition for a redundant hydraulic pump i would assume it would go to Nasa for their decision on whether it counts as significant or not as it's addition wouldn't have any affect on the vehicle for the primary mission. Nasa's investment in Spacex shows to willingness to innovate and adapt and i'm sure they don't mind the cast savings either.

      @@avid0g I realize that, but the engines pumps did start to operated and physically worked. The problem was that they ran out of the hypergolic fluid used to get the flame going inside of the nozzles. Called Triethylborane, this produces a sort of blue-green hue when you seen the engines light up before the RP-1 and LOX start to burn. The center core simply ran out of the TEA-TEB needed to get those other engines running.

      Yes, I saw Elon Musk's tweet of exactly this, just after the event.
      Many possible causes come to mind.
      I expect that the amount of stored TEA/TEB was supposed to be the same in all boosters. Near as I can tell, all boosters were expected to have the same quantity of engine ignition events.
      Some engine(s) may have completely shut off during "throttle down". That would then require extra engine ignitions in the center core.
      Perhaps some sensors used to detect propellant combustion were in error, causing a delay in shutting off the "lighter fluid" until a fall-back protocol confirmed thrust.
      Another possibility is that some center core engine(s) had real ignition problems, causing the TEA/TEB to be consumed for a longer time.
      In any case, I suspect there was greater-than-expected consumption of TEA/TEB in the center core.

    @RallyRat Před 5 lety +23

    I think they do two doglegs. The first is aerodynamic, to keep the ballistic trajectory well away from the landing area and to bleed off speed. They also do a propulsive dog leg so they miss the landing pad (or ship!) if there is a problem with the landing burn.

    • @jansenonline

      Didn't you mean that they DON'T do a dogleg when there is a problem? The doglegs are performed to change the ballistic trajectory to a new target, the LZ (pad/barge), when everything is nominal, right? You're saying it the other way around I think.

      Nah, if the landing burn fails it should crash land at the Landing Zone, think about it, around it there's SpaceX support "buildings" (might be a tent), the water lines for after land cooling, a forest, etc. a slab of concrete is the safest place for it to crash land.

    Thanks Tim. Even when things don't work perfectly, I still think that the 'Dan Dare'-style vertical landings are amazing. The comic strip was more than 50 years ahead of its time on that feature.

    No joke, Tim, I was driving into work today and thought 'I really hope there's a new Everyday Astronaut video, I could really use one'. Wahooooo! Thanks for everything you do broheim! In a virtual world of garbage, pointless channels, you and yours stand as examples of what the internet could and should be all about. High quality, meaningful entertainment that enriches the mind. Your videos are more than view grabs, they're works of art! Mad respect!

    Pretty cool video pretty good understanding and helped explain a lot I thought grid fins were lower but I can see their much more effective up high, should have known that already and totally understand the failure since I am a paraglider pilot and totally understand air pressureand the effects.

    Impressive explanation of how SpaceX charts a safe landing of their 1st stage boosters! It seems to me that this is an obvious built-in safety factor... i.e. if anything goes wrong, early, the booster will self destruct, if something goes wrong late, the booster will land harmlessly off shore. I am astounded that SpaceX has this level of fail-safe built into their RTL boosters! ... not to mention the fact that it still knew enough to survive the off-course trajectory, so that they could recover the booster, ... and LEARN!
    Todd, excellent video! Thanks for explaining this. You provide us muggles with a level of detail that most of us couldn't obtain. I have a profound level of trust in the space program, to keep us Floridians safe. I had never considered the fact that these boosters could crash over populated areas, but it's nice to know that this has been heavily factored into their equations! The dog-leg maneuver is clearly a built in fail-safe. It is built into the flight plan, as a late maneuver, only when everything is nominal. I never knew this existed. The booster is targeted for the ocean until very late in its landing sequence, then must aggressively target it's landing zone. Thanks for explaining this!

  • @WhereisRoadster
    @WhereisRoadster Před 5 lety +1

    One thing you are missing is that an explosion high up in the atmosphere will produce lots of shrapnel, but it will have time to get to terminal velocity, which for shrapnel is pretty small. For an explosion that is a few km above the ground, the shrapnel could still be more energetic then the terminal velocity, which could cause a fair bit of harm. Thus, activating the FTS close to the ground is actually more dangerous then just letting it hit the ground. In addition, as you said, it can't move very much, to the point where it could hit anything important.

    I think not only the legs kill rotation, but the gridfins has no speed and no airflow, witch make them rotate booster. So on the last few seconds stage almost stop and that's make rotation unable in case of aerodynamic. Nice video, buddy. I like it.
