SpaceX Starship missions

SpaceX Starship missions

SpaceX Starship missions

(OP)
Starting a dedicated thread here. After a pretty smooth flight test today, assuming no big anomalies occurred with the ground systems, it looks like SpaceX is back on track with testing and development. We should see more flights in the near future.
Both vehicles were lost before completing their full mission but a huge step forward today to see both executing the primary flight goals.

RE: SpaceX Starship missions

let's wait for a full survey of stage 0, but for now it looks like the "nay-sayers" have been "schooled".

good flight, could've been better.

Hot staging seemed to work well ... some details to be worked sure. I wonder if it'd be better to keep more engines alight and throttle them down more ?

I saw some pictures that show damage to a couple of the vertical tanks that were also damaged by debris from the first launch. Not enough detail to suggest if it was from debris or just blast effects. I think they are not for cryogenic storage anymore, maybe just water. I don't think anyone should think that there would never be any damage of some kind to the launch pad, given the amounts of energy involved. NASA experienced significant damage to the SLS pad that was not expected as well.

RE: SpaceX Starship missions

Let's wait for the investigation. I agree I expet some damage, but nothing like the previous launch. Now the water and plate solution seems to have worked really well.

Something I've asked on YT (Marcus House) ... Apollo and others ? had sparklers under the rocket, lit immediately prior to launch (to prevent fuel accumulating). but not so SpaceX ? Thoughts ?

Those sparklers under the shuttle? IDK, other than that the fuel was hydrogen instead of methane. I believe hydrogen has an exlosive range greater than most volatile vapors, or so I heard.

RE: SpaceX Starship missions

Wasn't sure about the Shuttle ... they wouldn't be under the SRBs !

Ok, the fuel could make sense ... Apollo was LH2/LOX, and I'll accept that H2 is more explosive than CH4 ... I still wouldn't want a cloud of Methane in the relatively closed environment under a rocket ...

The first stage of the Saturn V burned RP-1, a more precisely refined form of kerosene. I don't think they used the 'sparklers' under that rocket.
Yes, I think running the sparklers under the SRB's might have had some kind of unintended consequence, like a RUD on the pad, maybe sad

RE: SpaceX Starship missions

Launch track and disintegration debris pattern from the first stage... and the upper stage.. Flight #2. Hmmmm I wonder if the actual... farther-down-range... upper stage debris field(s) was also anticipated and built-into in the emergency planning.

Debris field model [predicted?]...


Apparent upper-stage debris field...


WX sat radar track of upper-stage debris...


I had presumed that the launch track would be thru the gap between south Cuba and Cancun MX. Boy-o-boy was I off base. The F#2 launch track 'threads' the gap between the Florida Keys and the Northern coasts of Cuba, Haiti, Dom-Rep and Puerto Rico. The debris from the F2 upper-stage appears to have ended-up in the sea just north of Puerto Rico. Hope there were no close-up/in-person witnesses land/sea/air.

I suppose that on-board engineering video/images/real-time-data were being held-back by SpaceX for mishap analysis...?

RE: SpaceX Starship missions

When SpaceX first discussed reusable hardware, I though it would be a real game changer. Being able to use a booster 4 or maybe 5 times would impart a huge savings per pound to orbit per launch.
I just watched a Falcon 9 booster complete it's 17th mission and the 250th recovery overall for SpaceX.

RE: SpaceX Starship missions

tb3...

The Falcon 9 is a proven 'winner'... Routine LEO missions are happening with 'with monotonous regularity'.

I hope SpaceX can Scale-up and make it happen with Starship launch vehicles... Routine LEO and beyond... 'with monotonous regularity'.
