Todd: Guidance and Nav saw something off nominal at T-1 min that they wanted to take a longer look at.

After that hold, the Flight Termination System transmitter/receivers had an issue, and teams needed to swap out the transmitter.  Range is now GREEN again!

Pressurization system was reconifured manually at the pad.  Teams actually when to the pad.

Todd Master, manager of DARPA's Launch Challenge, says Astra engineers continue assessing "off-nominal" data fr om the rocket's guidance, navigation and control system.

In the meantime, teams at Kodiak Island have replaced a suspect ground transmitter that would be used to send a destruct command to the rocket in the event of a major problem after liftoff.

Technicians from Astra also entered the pad -- wh ere the rocket remains fueled with kerosene and liquid oxygen propellants -- to reconfigure some helium pressurization bottles. This enables Astra to remain on standby for a possible launch before the end of today's window at 6:30 p.m. EST (2330 GMT; 2:30 p.m. Alaska time), assuming engineers can resolve the guidance, navigation and control issue that caused the countdown hold earlier today.

And the webcast is back. Update: Todd Master (Darpa Launch Challenger "master"): The collision avoidance was for the Space Station!

"No new information."  Honestly folks, this isn't looking good for today.  Things happen, not giving up yet.  44 minutes left in the window, but they need to be counting again in 28 minutes.

Стандартная процедура COLA. Сдвинули время пуска с 20:30 UTC на 20:55 UTC. На Электроне в НЗ так часто делают во избежение...

SCRUB!!!

Too bad. Today was the end of the challenge, so @Astra won't get any @DARPA reward money. It likely means they've forfeited the entire follow-on sums of over $10 million as well ($12 million total) unless they strike a backroom deal - unlikely, as others would protest fiercely.

Interview:  "If data was correct, could have caused a problem with the launch. Winning the challenge would have been nice, but getting to orbit is the goal."

ROCKET 1 OF 3, LAUNCH ATTEMPT 1
MARCH 2, 2020

Today, Astra began countdown of the first orbital launch as the final remaining competitor in the DARPA launch challenge. Our team decided to hold the launch at T-53 seconds after a sensor reported unexpected data that could have impacted the success of the flight. Out of our commitment to safety, and to increase the probability of overall success of the three-launch campaign, we have decided to prioritize fully investigating the issue over attempting to win the DARPA challenge today.

We are incredibly grateful to our team who have worked many late nights and weekends for the past few months to prepare our launch system for our first launch. We would also like to thank the team at DARPA, the FAA, and the team at Pacific Spaceport Complex for making an orbital launch attempt possible within a few days.

We remain determined to reach orbit and plan to attempt another launch attempt as soon as possible.  Thank you for the continued support as we move forward in our mission to observe, connect and improve life on earth.

DARPA's Todd Master, in post-scrub telecon: "We were really hoping to hand over a big check today, but we are very hopeful that the sort of things we put in place and the incentives we provided will continue to spur some innovation and get us to where we want to be."


3:15 AM - Mar 3, 2020

DARPA's Todd Master: With DARPA Launch Challenge complete, our intention is to remove the payloads from Astra's rocket and return them to their prospective providers.


3:22 AM - Mar 3, 2020

Astra's Chris Kemp: Expect another launch attempt in a matter of a week or two — not in the next couple of days and not in a couple of months. He says they will likely webcast the next launch attempt, which is expected to try to send a different payload suite into orbit.
