Scoop: Astra Space's tests contaminated hundreds of tonnes of soil & damaged a building at the Pacific Spaceport Complex Alaska on Kodiak Island. My latest for @newscientist [paywall]

I got Astra on the record for the first time. They say both test flights last year were successful, but that both ended early. Both landed on spaceport land, requiring over 230 tonnes of soil to be removed to the mainland for decontamination.
Debris from the first flight in July also damaged exterior panels on PSCA's Integration & Processing Facility. The damage was fixed by early spring this year. This damage increased insurance costs for @vectorlaunch - one of the reasons it did not launch from PSCA last year.pic.twitter.com/Fqd0jwfSTr
The boss of PSCA at the time told @SpaceNews_Inc that the launch had caused "no material damage to our facilities." However, minutes from a spaceport board meeting had a section entitled "Facility Damage Report from 7.20.18 launch".

Remember how an FAA official said all 5 of Astra's rocket engines failed on its 2nd flight (another great story by @jeff_foust)? Astra says that was incorrect. 2 engines on the rocket failed, the remainder were shut down to maintain trajectory.https://spacenews.com/astra-space-suborbital-launch-fails/ …
Good scoop! I've never heard of soil being removed for decontamination before... What did they do with the soil after treating it?
As I understand it, the soil is heated to vaporise the hydrocarbons, then heated again to destroy the gases. The soil is then just sterile dirt, and goes to landfill.
