With the latest launch of Starlink, SpaceX sets a record for rapid reuse

Zoom in / Falcon 9, Booster 1051, broke the sound barrier on December 13, 2020. It was back again for its eighth launch a little over a month later.

SpaceX continues to take great strides as it pushes the boundaries of reusing the Falcon 9 first stage rocket.

On Wednesday morning, the company plans to launch the next batch of 60 Starlink satellites, and reuse the booster number 1051. This will in fact be the eighth flight of this Falcon 9 missile – setting a new record for the number of uses for any single rocket core. SpaceX expects to reach 10 uses of at least one stage of the Falcon 9 later this year.

The upcoming launch attempt is also noteworthy as it would mark a rapid turnaround for this first phase. The missile last flew on December 13, launching the Sirius XM-7 mission in geostationary transport orbit. This 38-day period will significantly outpace the preceding transformation margin of Falcon 9’s first phase, which is 51 days. This indicates that the company’s engineers and technicians are continuing to learn best practices for recovering and refurbishing the missiles.

The Starlink mission is scheduled to launch at 8:02 AM EST (13:02 UTC) on Wednesday from the Cape Canaveral Space Force Station in Florida. Its launch was originally delayed by 24 hours from Monday due to unfavorable weather conditions in the offshore recovery area, where Just read the instructions Will wait for the return of the first stage. Then the important company delayed an additional day, say More time was needed for “pre-launch inspections”. It is not clear if this refers to the missile or the payload.

This will be the sixteenth launch of “operational” Starlink satellites, in addition to an earlier launch of experimental satellites. This mission is already the largest satellite operator in the world, and will bring the total number of Starlink satellites launched by SpaceX to over 1,000. Some of these satellites are no longer operational, are in the process of exiting orbit, or have already done so.

In starting to build this constellation, SpaceX owns it Introducing a public beta Select regions in North America and is expected to offer more widespread coverage later this year. First impressions It was generally positive.

At the same time, SpaceX is also working to address the concerns of scientists who are concerned that the large constellations of satellites transmitting the Internet from space will distort the night sky and damage astronomical observations. Last year, the company started adding “masks” to reduce the reflection of its satellites. However, Recent analysis From these “DarkSats” they indicate that more effort may be required.

Weather conditions for launch on Wednesday appear favorable for the mission, both at the launch site and in the recovery area. SpaceX should start live 15 minutes before take off.
