SpaceX Falcon 9 rocket aces eighth launch and “envelope expansion” landing

SpaceX has successfully completed the first of dozens of Starlink releases planned in 2021, simultaneously beating multiple rocket reusability records and finishing an “envelope growth ” booster landing .

Ending several days of delays, Falcon 9 booster B1051, an expendable upper stage, a flight-proven payload fairing, and 60 new Starlink satellites lifted off at 8:02 am EST, kicking off SpaceX’s 16th operational Starlink mission and 17th Starlink launching all around. Roughly an hour later, after turning up end over end, Falcon 9’s orbital second stage successfully released all 60 satellites to complete an exceptionally milestone-rich mission.

Starlink-16 is such a substantial mission for several unique reasons.

First of all, as previously discussed on Teslarati, Falcon 9 B1051 simultaneously crushed the world-record for aircraft turnaround and became the very first booster to successfully launching and land eight times, which makes it SpaceX’s “life-leader” in multiple ways.

“Last flown for the first time on December 13th, Falcon 9 B1051 is now advised to try its eighth orbital-class launching and landing only 36 days later, beating the 51-day world record by nearly a third (~30%) and simultaneously getting the first Falcon booster to launch eight times. If effective, SpaceX’s Falcon rockets will probably soon be mere days away from demonstrating yearly reusability. ”Teslarati.com – January 17th, 2021

Delayed from January 17th to the 20th, that schedule didn’t grip exactly but B1051 did become the first reusable rocket to drop below the 40-day turnaround markers, finishing two sticks and landings within 38 days, crushing the last world record of 51 times (also held by Falcon 9) by nearly two weeks.

Those milestones alone are major accomplishments for SpaceX’s workhorse rocket, leaving the Falcon Block 5 design upgrade just two flights from attaining its 10-flight design target and seven or seven times away from yearly reusability. The fact alone that SpaceX’s turnaround time is apparently quickening for fleet-leader (most flown) boosters serves as a clear indication that the design has nearly certainly reached that 10-flight goal and is probably capable of far more flights still. If that trend continues, Falcon 9 B1051 could complete its tenth and ninth flights as early as March and April.

Furthermore, even though a 38-day turnaround is significantly more than a magnitude from CEO Elon Musk’s long-held objective of 24-hour reusability, it will signify an order-of-magnitude advancement from SpaceX’s original booster reuses, that averaged 200-500+ times between flights.

In accordance with SpaceX, Starlink-16 and booster B1051’s last milestone was successfully expanding Falcon 9’s usable envelope by landing exceptionally large floor drains. Completed without any apparent issues, that success usually means that SpaceX will be able to enlarge the selection of states Falcon 9 can launch and land in, enhancing the probability of favorable weather later on.
