Elon Musk and his SpaceX have made HUGE progress for our exploration
and development of space. This booster made 23 prior flights.

SpaceX Falcon 9 booster collapses in a fireball on the droneship, ending
a streak of 267 successful landings

Update 5:20 a.m. EDT: SpaceX is scrubbing the Starlink 9-5 launch from Vandenberg Space Force Base to allow more time to review the data from
the B1062 landing failure.

For the first time in more than three years, SpaceX lost one of its
reusable Falcon 9 boosters during a landing attempt amid the Starlink
8-6 mission on Wednesday morning. As it was touching down on the
droneship, rCyA Shortfall of Gravitas,rCO a green flash could be seen around the Merlin engines before the engine section was engulfed in flames and
the booster toppled over and exploded.

While recovering the booster is a secondary part of the mission compared
to the deployment of the 21 Starlink satellites, SpaceXrCOs business model
is based on the reusability of its rocketsrCO first stage boosters.
Whatever issue ultimately led to the demise of the booster, tail number
B1062, snapped a streak of 267 successful booster landings.

Prior to the Aug. 28 mishap, the most recent failure happened on Feb.
16, 2021, when the booster B1059 met its end amid the Starlink 19 v1.0 mission. That landing attempt was with SpaceXrCOs rCyOf Course I Still Love YourCO droneship.

SpaceX decided to move forward with the launch of the Starlink 8-6
mission after weather concerns stymied the launch of four astronauts on
the Polaris Dawn mission. The company announced it would launch
back-to-back batches of Starlink satellites on Falcon 9 rockets from
both Cape Canaveral Space Force Station and Vandenberg Space Force Base Wednesday morning.

Starlink 8-6 was first up to bat, launching from Space Launch Complex 40 (SLC-40) at 3:48 a.m. EDT (0748 UTC). It was set to be followed by the Starlink 9-5 mission from VSFB, but SpaceX opted to hold off on that for
now rCLto give the team time to review booster landing data.rCY



The Wednesday morning flight of B1062 marked a record 23rd launch of a booster. This made it the flight leader for SpaceX. It previously
supported the launches of two GPS satellites, two astronaut mission (Inspiration4 and Axiom Mission 1) and 15 Starlink flights.

The issue came about 8.5 minutes after liftoff, when B1062 made its
landing attempt on ASOG. It wouldrCOve been the 342nd booster landing to date.

Onboard the flight were 21 Starlink satellites, including 13 that
feature Direct to Cell capabilities. The successful deployment of the satellites brings SpaceX up to 155 DTC Starlink satellites launched to date.

During its mission, the astronauts of the forthcoming Polaris Dawn
mission will perform a on-orbit demonstration of Starlink connectivity. Mission commander Jared Isaacman told Spaceflight Now in July that this
will be a good stepping stone to help push forward communication in space.

rCLThere is only so much capacity on the TDRSS (Tracking and Data Relay Satellite System) satellites. Ground stations, thererCOs not many of them. They are also in demand. And if you can create a constellation, not just
in low Earth orbit, but in lunar orbit as well, you can transmit very effectively over laser links,rCY Isaacman said. rCLIt is a good step in that direction and SpaceX is already moving in that direction of making
available those laser links on Starlink to other providers. So, itrCOs
really awesome just for all of commercial space.rCY

Polaris Dawn is now set to launch no earlier than Friday, Aug. 30, after weather conditions forecast for their planned return from space pushed
the launch date off of Wednesday.
