Launch System 2: Upper Stage Engine

The upper stage of Astra's Rocket 4 will use the vacuum variant of Ursa Major's Hadley, an oxygen-rich staged combustion engine fueled by liquid kerosene that will provide 6,500 pounds of thrust. Learn more here: astra.com/laun...

We believe in you❤❤❤

I hope in the next launch the rocket will start moving towards camera to complete the SpaceX, SpaceY meme

What's the first stage engine?

[@AeonExploration]

a modified Firefly Reaver (they have IP on it)

I regret investing in Asstra

[@HackerFlavio]

that looks like the messiest rocket engine i have seen in a while

[@HexaSquirrel]

That’s what happens when you design a 6500 kibf ORSC engine. Also, much of those orange high voltage lines you see need to be long so they can connect to S2 and it’s flight computers.

[@basestone]

Yeah, it looks a bit prototypey. Like you do if you just want it to work and carve out the details and the cable management later.
Problem is, that "later" more often than not never comes. This philosophy was Astra's main mistake in their first try and now with their second, they are really time constrained.
Idk how early in their development Ursa Major is but for Astra - basically an aluminium-tube-manufacturer at this point - I don't have high hopes.

​@@HexaSquirrelwhy so small ORSC engine?

[@FrankBenlin]

As you rocket scientists know, the more complicated thing are, the more that can go wrong. Time to rid these engines of this layer of mechanical entrails they are wrapped in. Simplification means reliability. I know you will get right on this, thank you.
But seriously, something needs to be done about this.

Not looking forward to being “De Listed” - Hopefully this would be the Silver Bullet 😅

Ain't gonna lie, I'm very disappointed in you guys. I lost a lot of money.

[@East7West9]

avg down silly...otherwise, why did you buy when you did? Look in the mirror for real dissappointment

[@thedarkside13]

@@East7West9 I bought it to impress your mom and sister more.

You invest at your own risk. Everyone knows space is hard, so the only one you could possibly blame is yourself for not knowing what your getting in to. I invested as well, but not just for money, but also because i believe in their mission. I haven't sold my stock yet and i won't. I'm proud to be a shareholder of Astra.
If you want to earn quick and easy money, spaceflight investments are not the way my friend....

@@East7West9 it goes down every month, cost averaging wont save you lol

[@agaragar21]

They've given up on their OWN technology ?????..........the stock is not worth even $0.02
