Do we have an accurate T-0 time?  I estimated by the Tweet timestamps.

You can fool some of the people some of the time, but you can't fool all of the people all of the time.
Quote from: Tweet
Rocket launch startup Astra has joined an elite group of companies who can say their vehicle has actually made it to orbital space – earlier than expected.
"orbital space" ? I'm very confused...
They have constructed a purposely vague sentence to allow the company to muddy the difference between a suborbital flight and an orbital flight.

This is what 390 km altitude and 7.2 km/s looks like. 7.5 km/s gets you around the earth multiple times (at least without accounting for drag). So, that is 96% to orbit.

I think the phrase goes " Although you can fool all the people some of the time, you can fool some of the people all the time. And those are the ones to focus on."

I want to think thats TechCrunch being TechCrunch but Astra's PR seems all over the place though

As test I'd call it a success even if it fell slight short of target. All big milestones were ticked off.

It's a dreadful old cliche but every failure is a dress rehearsal for success*

So not bad. Pretty good in fact. As long as they can figure out what went wrong and fix it. Still on course for The Aerospace Corps 5/8 rule





*Unless you run out of money first of course.  :(

The successful parts of this mission should help secure more investment funding if needed.

"FAILURE" in the title is definitely not what I would use.  Given that they didn't plan on actually making orbit until flight 3.3, this flight accomplished all of their planned objectives and then some.  Perhaps we can just change "FAILURE" to "Sub-orbital".

They were only about 500 m/s short of orbit, and an eastward launch from a low latitude site adds about 400 m/s, compared to polar orbits from Alaska.  So they are very, very close to what is needed.  And a much leaner team than even RocketLab or SpaceX, so lower costs seem possible as well.
