SpaceX delivers 60 more Starlink satellites in first launch of 2021, and sets new Falcon 9 rocket reusability record

SpaceX has launched its seventeenth batch of Starlink satellites during its first mission of 2021, using a Falcon 9 rocket that was flying for the eighth time, and that landed again, recording a record for its reusability program. This puts the total Starlink constellation size at almost 1,000, as the company has expanded its beta access program for the service to the U.K. and Canada, with a first deployment in the latter country serving a rural First Nations community in a remote part of the province of Ontario.

The launch took off from Florida at 8:02 AM EST (5:02 AM PST), with delivery of the satellites following as planned at around an hour after lift-off. The booster on this launch flew seven times previously, as mentioned - including just in December when it was used to deliver a SiriusXM satellite to orbit to support that company's satellite radio network.

Today's launch was also notable because it included a landing attempt in so-called envelope expansion" conditions, which means that the winds in the landing zone where SpaceX's drone recovery ship was stationed at sea actually exceeded the company's previously defined safety window for making a landing attempt.

As a result of today's success, SpaceX will likely now have higher tolerances for wind speeds in order to attempt recovery, which should translate to fewer cancellations of launches based on weather conditions in the landing zone.
