Although the weather wasn't ideal, @Astra met launch criteria yesterday by resolving a few tech items, including fueling and loading cryogens. The next launch oppty will be on 3/2 at 11am AK/12pm PT. For an explanation of the scrub: https://www.youtube.com/watch?v=og3xva0vB6s ...

Here is a Google Earth image of the Kodiak launch area. Where are the new LP-3A and LP-3B sites? I am guessing the sites I've called B1 and B2 here? Can someone who knows confirm or deny? @MasterActual ? @johnkrausphotos ?




10:14 PM - Mar 1, 2020

OK so here is my revised attempt




 Todd Master@MasterActual 10:45 PM - Mar 1, 2020

You have points correctly now, though the labels are wrong. The "3A?" is actually designated as "Pad C."

That was originally a gravel pad with a small concrete apron that we worked with PSCA to upgrade for #LaunchChallenge to mostly replicate their recently constructed "Pad B"


Jonathan McDowell✔@planet4589 11:03 PM - Mar 1, 2020

Here is my revised attempt. Best of luck to Todd and crew for tomorrow's launch attempt.

Here's a better graphic from our peeps at PSCA.

DEFINING LAUNCH SUCCESS
MARCH 2, 2020

Rocket "2of3" and "3of3" in production at our Alameda factory

Today, we are kicking off a campaign of three launches.

Our latest rocket will launch fr om Alaska's Kodiak Island in a bid to win the Defense Advanced Research Projects Agency's (DARPA) Launch Challenge. The  winning company must successfully deliver a payload into low-Earth orbit on short notice—then be prepared to do it all over again from a different location, within a few weeks. While the second launch will also take place in Kodiak, the goal is to encourage the development of small, nimble rockets that can deliver small satellites quickly, from mobile launch pads anywhere in the world.  We like this goal, and are honored to support our country's strategic space capabilities by competing in the Challenge today.

When we founded Astra three years ago, we stayed under the radar. No website, no press tours of our 250,000-square-foot Bay Area facility, no flashy trade show booths. We set out to build a new kind of space company, and we wanted to be free to experiment, to iterate, over and over again, holding ourselves to our own standards, instead of the expectations of others.

Rapid test and iteration are the cornerstones of our development process. We've performed thousands of rocket engine tests at our headquarters in Alameda, a few hundred feet away from wh ere those engines are designed and built. We can afford to experiment quickly and repeatedly because our rockets are far less expensive. The rockets are primarily constructed from lightweight aluminum, instead of costly composite and 3D printed materials.

During the flight there will be a few major milestones along the trajectory to orbit. The more we accomplish, the more we learn, and the closer we are to reaching orbit. Success for this flight means we accomplish enough to make orbit within three flights, which we have defined as reaching milestone 5 or beyond... separating the upper stage successfully in outer space.  We believe that once we reach this milestone, we'll be no more than two flights away from reaching orbit.

We have a second rocket ready to go ("2 of 3"), and another will be ready right after that, and we are confident that we will reach orbit because the faster you learn, the faster you succeed.

Ad Astra,

Chris and Adam

DARPA says today's launch time has been postponed a bit to ensure Astra's rocket does not get too close to another object already in orbit. A new launch time has not been announced.
