Fallen Debris from SpaceX Satellite Launch Crashes on a Farm (space.com) 95

Posted by EditorDavid from the sky-is-falling dept.
180 miles east of Seattle, "A pressure vessel from a SpaceX Falcon 9 rocket stage fell on a man's farm in Washington State last week," reports the Verge, "leaving a '4-inch dent in the soil,' the local sheriff's office said Friday."

Space.com reports: Although Falcon 9 rocket successfully delivered 60 Starlink satellites to orbit last month, the rocket's second stage didn't deorbit properly after completing the mission. The second stage is the smaller, upper part of the Falcon 9 rocket that separates from the main booster to take satellites to their intended orbit. While the main booster returns to Earth for a landing (so SpaceX can refurbish and reuse it on future launches), once the second stage has completed its role in the mission, it is either intentionally destroyed or left to linger in orbit.

Typically it conducts a "deorbit burn" that sends the craft on a safe trajectory to burn up in the atmosphere above the Pacific Ocean. But this time, something went wrong: According to Ars Technica, "there was not enough propellant after this launch to ignite the Merlin engine and complete the burn. So the propellant was vented into space, and the second stage was set to make a more uncontrolled re-entry into the atmosphere." So, instead of burning up over the ocean, the rocket stage ended up breaking up in the sky over the Pacific Northwest — the fiery display visible not only from Washington but also from surrounding states and parts of Canada — just after 9 p.m. local time on Thursday, March 25, or midnight EDT (0400 GMT) on Friday, March 26.
Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, calls it "a bit of a puzzle" that the stage wasn't de-orbited under control back on March 4, telling the Verge that it "looks like something went wrong, but SpaceX has said nothing about it. However, reentries of this kind happen every couple of weeks. It's just unusual that it happens over a densely populated area, just because that's a small fraction of the Earth."

          It's the same with Tesla. Waymo demonstrates a safe, reliable self driving car and Tesla fans say it will never scale, the hardware is too expensive and it can never go beyond Portland. Meanwhile even after 5 years of missed deadlines Tesla is right on the cusp of releasing a software update that enables full self driving robotaxis, although any failures of the autopilot system are down to the user.

          The cult is very real and far, far worse than the Apple one ever was.

      For that particular flight, 2nd stage don't have enough propellent to do a deorbit burn. So they have to let gravity to do that for them. Had they do a control burn, they'd be aiming for Point Nemo in South Pacific.

      It's junk. SpaceX doesn't have any use for it. Neither does the farmer. SpaceX can dispose of it properly. Or the farmer could put it on display, perhaps at his booth at local farmer's markets. SpaceX is just glad this hit the ground and not a building or person.

    • Because of the sensitive nature of rocket hardware, special laws were passed, stating that the remains of space equipment always remains the property, and responsibility, of the country and corporation that launched them.

      So, in this case, SpaceX was required by law to clean up the remains of the spacecraft, if that was necessary.

      As to a legal case - no, it would not be interesting. The law on bits of spacecraft are unambiguous.

    • According to the Outer Space Treaty, the country of origin of any space vehicle is responsible for it and has ownership of it and is liable for for any damage caused by a spacecraft.

      Of course, since its a United States launch that landed in the United States, they would probably pass the cost on to SpaceX and their insurance.

Unlike a meteor that crosses the sky in an instant, the yellowish glowing debris was visible for at least 30 seconds.

      IT is a large and light object, so it fall very slowly, and so it wouldnt' cause much damage to things it fell on, unless they are very fragile.

      A boat wouldn't sink, a plane on the ground would need some repairs. A plane crashing into it as it fell would suffer damage, but that would be really unlikely - there's a lot of air between each plane - and could be serious. But even then, I'd give the plane a good chance to land - a strike in most places wouldn't prevent the plane from landing.

    • Orbital objects these days are usually disposed of safely, either by deorbiting them over the Pacific and into the Spacecraft Graveyard [wikipedia.org] or sending them into a graveyard orbit beyond geosynchronous orbit, but sometimes things go wrong, as happened here. Other options have been studied including lunar impact and heliocentric orbit, though I'm not sure either has been used. Starlink and OneWeb at least have the option of being moved into a disposal orbit where their orbits will naturally decay and they'll burn

      • No satellite have enough fuel to send it of earth gravity. GEO satellites are raised a little bit a decommissioning. All other fall to the ground. Many uncontrolled at random places, but very few have pieces large enough to reach the ground.

    • It doesn't look like the tank left a 'dent' as much as the heat seared away the grass under it where it finally came to rest. It easily could have impacted elsewhere and bounced/rolled there.
