Astra Orbital Attempt Upcoming

#1
Yazata Offline
Astra is a really tiny little company in the Rocketlab space, trying to develop an even cheaper small satellite launcher. Their little rocket isn't reusable, but is slated to only cost about $2.5 million. (Compare that to ULA's powerful Atlas V which costs close to $150 million. Of course the Atlas can send heavy landers to Mars, but many customers don't need that.) Astra hopes to be able to launch about 400 pounds of payload into low Earth orbit with their little rocket. Several little cubesat sized payloads per launch.

They apparently hope to try to launch a demo flight tonight 10:00 PM EDT, 7:00 PM PDT, 2:00 UTC Wednesday. The launch site will be one of America's lesser known launch complexes, the Pacific Spaceport Complex in Kodiak Alaska. This launch site isn't used a whole lot, and has mostly been used to launch suborbital target missiles or anti-ballistic-missile interceptor rockets in ABM tests. (If North Korea tries to launch ICBMs at the US, they would come across the north Pacific.)

They say that they are too small to have a crew of videographers to live-stream their launch, but they hope to tweet their progress. (They nevertheless have a very good company introduction video below.)

I like Astra in part because they are based in Alameda, right next to Oakland and across the bay from San Francisco. If you ever watched the Mythbusters, you remember the 'Alameda runway' where they conducted many of their experiments. This is the former Alameda Naval Air Station, which was huge during the Cold War up until 1990 or so when it was closed. Astra has their rocket plant in some of the former Navy buildings, and even conducts rocket engine static fires on the same runway.

Yesterday's launch was scrubbed due to some undisclosed problem loading fuel.

They aren't going to try tonight because of upper level winds. So the next attempt is slated for Thursday 7 PM PDT, 10 PM EDT.

T - 15 minutes. Brief hold as they top off the fuel tanks.

They might not successfully orbit their little rocket, and to tell the truth they don't think that they will. This is the first try of three attempts that they anticipate that it will take to get up there.

But even if they don't get to orbit this evening, check out this photograph of their Kodiak Island launch site. (Photo by well-known space photographer John Krauss from Astra's twitter page.)

Astra and Kodiak's Pacific Spaceport complex are giving Rocketlab and NZ's Mahia Peninsula a run for their money in the beauty category.

Holding again at t - 3 minutes due to problems with the ground support equipment.

Launch being scrubbed until tomorrow due to low pressure in the water deluge system.

Early word is that weather conditions (upper level winds) aren't looking good for a launch tonight.

Astra got their little rocket off from Kodiac yesterday Sept 11, 2020. It rose into the sky, then the engine cut off for some as-yet unknown reason and the rocket fell back and exploded with a loud detonation. Astra expected this first attempt to fail and that it will take them several attempts to reach orbit. They did want a successful first stage burn though, and they didn't get that. They say that they got a lot of telemetry though.

The talk is that the engine quitting was commanded and intentional. The reason is that the engine steering system was oscillating and the rocket was starting to become uncontrollable. So the engine was commanded to shut down as a range safety feature so that the rocket would fall in a safe area.

Edit: The above, space-geek gossip at the time, has been verified by Astra themselves.

"Early in the flight, our guidance system appears to have introduced some slight oscillation into the flight, causing the vehicle to drift from its planned trajectory leading to a commanded shutdown of the engines by the flight safety system."

Astra is back with a second attempt today. They will be trying to get their tiny little rocket into orbit today after launching from Kodiak Alaska. There won't be a livestream but they will be tweeting. Locals are unlikely to be out watching since it's Alaska in the winter. But they may be out because it's Alaska and Alaskans are tough. (You've all seen Deadliest Catch about Alaska crab fishermen.)

Apparently no need for security there. That guy by the fence might as well be a rustic cemetery caretaker.

Take away the mountainous background and the fact that the facility is above ground, and the scene echoes the Cold War location of an isolated missile silo in a remote area or a barren spot of the Great Plains. Unsuspecting traveler passes by just as the lid opens up for a monthly test, realizes there is a nuclear bomb and rocket technology lurking in the middle of nowhere.
