Starship tests: Planned 150 meter hop with SN5 (Aug 4 -> success)

Summary:

SpaceX plans to fly a Starship prototype to a height of 150 meters on July 13 or the following days

Main Question or Discussion Point

SpaceX doesn't have a public test plan, but they need to close a public road to fire the engines, and road closures need to be announced in advance - including their reason. In the next days SpaceX plans a static fire (engine fires but the spacecraft is fixed to the ground), and Monday next week (the following days are backup dates) they plan to fly up to 150 meters high. Tweet. As usual: The test might get delayed, cancelled, or the vehicle might disintegrate before. If not, we can get the first free flight of a "real" Starship prototype. Starhopper flew to 150 meters before but it was a much more primitive prototype - walls so thick that it would never make it to space, for example. SN5 doesn't have the payload section attached but that is largely more of the same and it doesn't need to withstand the high pressure the tanks have.

Edit: Cancelled for now. They are working on the hardware.

Edit 2: Maybe with one week delay (Week of 20-26).

The successful static fire of SN5 just completed.

Hop attempt in ~33 minutes.
Or shortly before the next hour.

Livestream

Edit: A siren warns of the test 10 minutes before the hop, that happened 18:44 local time, so 18:54+ for the hop, could happen nearly any minute now.

Edit2: Looks like it will take a bit longer. Venting reduced, they might remove the fuel, fuel it again and try again.

Another attempt is on the way, the vehicle is being fueled and the engine is cooled down in preparation of a hop. In the chat people think they heard the siren, that would make the launch attempt 10 minutes away. That would be unusually fast, from the fueling I would expect an attempt in ~30-50 minutes.

Edit: Everydayastronaut reports hearing the siren (livestream)

Launch 18:54 local time?

IT FLEW!

And it's still standing.

Such a surreal flying object.

Here is a video

A flying grain silo :))

Jokes aside, they are making impressive progress. Also, the way they work is so different from how conventional wisdom says that you should run large development project.

Love it. Any word or pictures on whatever was blown off the test stand(?) @ ~12 seconds into the SpaceX video?

Not sure what it was (here are some people speculating), but it might be related to the incomplete structure: SN5 has a single Raptor engine that is offset from the center (the final design will have 3 center engines in a triangle and three outer engines), which means it doesn't launch vertically, it goes sidewards in addition to upwards. That means the exhaust hits some things that are not meant to be hit by exhaust. The launch pad might be quite preliminary, too.

Maybe that's part of what Musk meant by "several short hops to smooth out launch process". They want to reduce the damage a launch does.

What about those flames around the engine as it is landing? Don't think those are supposed to be there. Another item to be smoothed out?
