(OP)Senior Forum Moderator  07/23/2020 04:01 PM  Report Abusive Post Report Copyright Violation | Basically, lets accuse Russia of a f*ck up, even though no f*ck up occurred. Quoting: Anonymous Coward 79156579 And then lets investigate their non-existent f*ck up and wag the finger at them. Can't tell if you're a troll, a shill, or just plain stupid. You can visibly SEE the automated system causing the cargo vehicle to oscillate just a few meters from ISS. That is unacceptable and we need to know why they didn't call off the approach at that point or go to manual control. I mean, the auto-dock docked, did it not??? Quoting: ACSo because we got lucky this time and it happened to work itself out, there's no issue here and we should just ignore the close call? And yeah, I don't blame Russia for being skeptical of the SpaceX first stage 'self-landing'. Quoting: ACOh my god, you are so stupid. They aren't skeptical that the first stage landing happens, everyone KNOWS it happens, I've witnessed it in person many times myself! The first stage landing has NOTHING to do with the manned mission. It does not matter if the first stage successfully lands or not, there's no one riding on it at that point! You want us to ignore a near collision between the cargo vehicle and ISS, but you expect us to be "skeptical" of SpaceX's first stage landings? I smell a damn rat in my thread.  |

God has fixed the time for my death. I do not concern myself about that, but to be always ready, no matter when it may overtake me. That is the way all men should live, and then all would be equally brave.” -Stonewall Jackson "The Bible that is falling apart usually belongs to a person who is not." - Charles Spurgeon “I apprehend no danger to our country from a foreign foe . . . Our destruction, should it come at all, will be from another quarter. From the inattention of the people to the concerns of their government, from their carelessness and negligence, I must confess that I do apprehend some danger. I fear that they may place too implicit a confidence in their public servants, and fail properly to scrutinize their conduct; that in this way they may be made the dupes of designing men, and become the instruments of their own undoing. Make them intelligent, and they will be vigilant; give them the means of detecting the wrong, and they will apply the remedy.” “If we abide by the principles taught in the Bible, our country will go on prospering and to prosper; but if we and our posterity neglect its instructions and authority, no man can tell how sudden a catastrophe may overwhelm us and bury all our glory in profound obscurity.” -Daniel Webster |

You have to realize that although their relative velocities to each other are minuscule compared to orbital velocity, the mass of the cargo ship is quite high and the pointy end that goes into the docking port makes for a very nice high pressure point on the hull if it collides rather than docks. It can damage solar arrays that are present near the docking port and puncture the hull if it goes out of control. |

NASA was going to require them to do a lot more work to certify that a propulsive landing would be safe. SpaceX had started unmanned testing of that feature using the super draco engines, but ultimately cancelled it. Doing a propulsive landing with Dragon is no longer "in the path" to their ultimate goal of Mars missions. Starship is their new path to the moon and Mars and while it will propulsively land, it will require its own testing campaign that is already underway and distinct from Dragon. |

It’s still quite eye opening though to realize the physics behind it all. I will say this, I’ve love tapped the podium at RV parks in my early days RVing with my 32,000 lbs motorhome and ripped one right out of the ground at about .5 mph caused a blackout and a water leak and asked never to come back so ... there’s some truth to it. |

Exactly, it's very important that the pointy end goes into the docking port that was designed to receive it, not the hull of the vessel instead. You don't want it to stab the hull, even at a sedate pace of a few miles per hour. In games like Kerbal Space Program there's no consequence for bonking ships together at those speeds, but real life is much less forgiving. Last Edited by Astromut on 07/23/2020 04:33 PM |

Also, submarines for the same reason. You cant un-fuck the doom pussy once her cherry's popped. Quoting: Anonymous Coward 78725014 At least on the space station the pressure differential between you and outside is, at most, 1 atmosphere of pressure. In a sub the pressure differential is many times greater at depth. Still, Foale and his crewmates on Mir came very close to losing enough pressure to start losing consciousness. |

User ID: 56270897 United States07/23/2020 05:14 PM  Report Abusive Post Report Copyright Violation | No, in fact this kind of issue resulted in actual collision between a cargo vehicle and Mir... All the more reason why we need answers for why they failed to abort the approach. Meanwhile they complain that it's not safe for SpaceX to conduct automated docking at ISS. Looks to me like they're living in a glass house today. I was the last journalist to talk to Mike Foale before he went up and axed him if he was worried about safety on the MiR. Always wanted to ask him the obvious followup afer the crash and the fire. It is concerning about why the russkies couldn't put down the vodka long enough to do something. Maybe they're looking for more holes. Proud to be UnV'd There is one constant in life: If you build something worth having, someone will try to take it or destroy it.

Although the time it took to get to the ISS, and the amount of weight/supplies is pretty impressive. |
