B7.1

History

The aft dome barrel assembly section of B7.1 was spotted by Starship Gazer in front of the High Bay on March 22, 2022. It was later prepared for sleeving.

A common dome section was located by NASA Spaceflight on June 7. The test bank was seen being stacked in the High Bay on the night of June 9/10. Welding work was observed on June 13.

Preparations were made for testing B7.1 when the “can crusher cap” was moved to the launch facility on June 16, at the same time B7.1 was prepared for transport and then moved to the launch site shortly after. The test tank was lifted onto a stand on June 19, and the “can crusher cap” was placed on top.

The tank underwent testing on June 28, with second test occurring on July 19. Another test took place on July 21 where a small pop was observed. The structural test cap was removed from the top of B7.1 on July 23. With the removal of the test cap, a new test occurred on July 27.

Following the conclusion of testing, B7.1 was returned to the production facility on July 29 and placed in the Mid Bay.
