I like the checklist down the left side that that youtube channel has.

Spacex is currently moving the lifting crane away from the launch site.

People are guessing that SN9's launch will be no earlier than noon EST and probably later into the afternoon.

It's looking like the launch is within the next 60 minutes. Elon is onsite.

I recommend using EJ's twitch channel to watch the launch because he will mix between SpaceX and NASASpaceFlight's coverage.

People are guessing launch is near the top of the hour. (30 minutes)

Why is this flight only 10,000 feet wasn't the last one 50,000?

How are they planning on landing s9 with s10 sitting so close to the launch pad? Do they land in a different area?

The Flight is to 10km or ~33,000ft. The change can be for several reasons. Things like high elevation winds, they can decrease amount of fuel loaded or minimize maximum vertical velocity.

The two starships are about 80 meters apart. The landing pad is further away off to the left of SN10. The use of highly zoomed cameras makes everything seem closer together than they really are.

"Reaching its peak altitude of about 10 kilometres, the spacecraft then hovered momentarily in mid-air, shut off its engines and executed a planned "belly-flop" maneuverer to descend nose-down under aerodynamic control back toward Earth.

The trouble came when the Starship — after flipping its nose upward again to begin its landing sequence — tried to reactivate two of its three Raptor thrusters, but one failed to ignite."

"The rocket then fell rapidly to the ground in a roaring ball of flames, smoke and debris — six minutes and 26 seconds after launch. No injuries were reported."

Here's a well done compilation by NASASpaceFlight of today's SN9 flight from various angles.

A couple things to note in the video is right after the crash, you can see the nose of SN9 impacting the ground last. This results in the release of the oxygen stored in the header tank at the tip of the rocket. It results in the release of a large white cloud. It shows that indeed, oxygen doesn't burn. Also you can see 3 or 4 Composite Overwrapped Pressure Vessels (COPV's) flying around or skidding on the ground. These are compressed nitrogen and used for steering the rocket.

Landing pad after the crash. Check out the fence on the right hand side of the picture next to the road.

Elon thinks a trip to Mars will cost 200k a seat in like 20 or 30 years.

NASA will be able to do it for like 1 billion a seat though

Before the SN9 launch, John Insprucker of SpaceX said that they plan on launching SN10 towards the end of the month. However, the FAA made an announcement that they will be conducting an investigation of the crash. Who knows how long that's going to take.

I'm sure SpaceX already knows exactly what went wrong and likely how to fix it.

If I had to take a guess the thrust from 1 engine was less then the thrust needed to not crash. I assume it will take the FAA a month to come up with that.

I wonder if it is more to do with crashing so close to SN10. At the very least they have no issue hitting a target. It is literally a prototype like the FAA should know that is a non surprising outcome.

Not directly SpaceX related but the Perseverance Rover is landing (in some form) on Mars tomorrow. The landing sequence starts around 3pm EST. Coverage starts an hour earlier.

Landing is about an hour away!

Cool JPL site that reenacts what is happening to the lander in realtime.
