SpaceX has launched its 17th 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 UK and Canada, with a first deployment in the latter company 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 delivery 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.
