content: If the firey end points towards space, you will not be going to space today.Looks remarkably similar to the Russian launch 11 years back... in that case, an IMU was incorrectly mounted, so the rocket's guidance control algorithm failed to keep the craft on steady flight, and it broke up in flight after trying to target 'earth' instead of 'space'.Edit: got to love this quote from the CEO, trying to make a failure sound as successful as possible, emphasis mine: "Our first test flight met all our expectations, achieving a great success. We had a clean liftoff, 30 seconds of flight andeven got to validate our Flight Termination System."

content: The only large concern is if they have enough funding to get it right. SpaceX got their first rocket right only on 4th attempt for which they scrambled the last money to do it.

content: Hard to see how the flight termination system did activate there, unless their idea of flight termination is engines turning off, which still means you get a 33 tonne rocket falling towards the ground at some pace. Normally FTS would 'unzip' the rocket using explosives, which would mix LOX/fuel and destroy any large component.

content: looks like you need to go through the checklist a few more times before the next launchbut the company does work on "short range surface to ship missiles" and this launch was short range and it looked like it was trying to hit a ship so maybe they just put the ship hunter killer program on the control system by accident? I think the rocket decided its going to try to hit a ship...I imagine they get angry like a klingon relegated to logistics ... (and that's how a romulan battle cruiser gets taken out by something akin to the UPS truck)

content: Quote from: tom66 on March 30, 2025, 08:16:39 pmUnpowered, unstable rocket slaps into the water at speed seemed to be a pretty effective system that terminated the flight.The idea of triggering a flight termination system makes more sense at higher altitude and higher speed, where the vehicle's landing footprint would be very difficult to define accurately. As I see it, this would not be the case for this launch. In fact, activating such a system at any altitude would result in dispersal of fragments over a wider area - likely damaging the launch site - than allowing it to fall into the bay a couple of hundred metres away and blowing up at ground level, where the water would have absorbed of a fair amount of energy.

content: Fun to watch how it starts going straight up, then starts to oscillate a bit, and more, and more...Seems like they need to hire a summer trainee to tune that PID loop before the next launch. Maybe decrease P, add some D, hmm?

content: I see snow in the video, was that launch from a location inside Norway?Asking because I always thought the preferred locations are near Equator, to benefit from the Earth rotational speed. Isn't that so?

content: Quote from: RoGeorge on March 31, 2025, 12:41:13 pmDepends on what you're launching. For a geostationary payload then having equator speed boost is useful. For LEO then it's not such an issue. Most launches are LEO these days, for instance, Starlink is all LEO.

The Huntsville Business Journal published a nice biography of her. Huntsville was the location of the Project Management Office (PMO) for the Saturn space program and the location for the the PMO for the US Army's Missile Command (MICOM) (my connection to Huntsville).https://huntsvillebusinessjournal.com/news/2025/02/10/maria-von-braun-wife-of-dr-wernher-von-braun-has-passed-away/

content: Quote from: tom66 on March 31, 2025, 01:15:24 pmIt's not just speed boost from Earth's rotation, you cannot launch straight to the desired orbit direction, so it's an additional energy loss on adjusting the trajectory. As of LEO orbits, they vary. But unlike GEO, there is much less delta-v constrain, so detriment from launching from suboptimal location is much lower percentagewise. Location does not really matter for polar orbits as long as you don't need to fly around populated areas.Proton GEO launch as an example:
