SpaceX Transporter-2 mission shows promise and challenges of mass rideshares

As SpaceX gets set to launch Transporter-2 early Friday evening, this second SpaceX mass rideshare is showing the promise of regularly scheduled missions, but does come with some challenges. Oh, and there's lot of innovative technology being launched. The exact number of payloads on Transporter-2 has not been released yet but will be smaller than the Transporter-1 mission which had 143 satellites including 10 SpaceX Starlink satellites, and nine Canadian satellites. SpaceX was dealt a blow on May 10 when the Federal Aviation Administration (FAA) denied the launch license of Momentus for their space tugs Vigoride. Momentus had two space tugs scheduled to be a part of the mission with upwards of 49 small satellites. Combined with another 88 or so satellites scheduled for the mission, the Transporter-2 mission would have had about 147 small satellites or hosted payloads on-board. Canada's Kepler Communications was to have had two satellites on the Momentus tug. They are now being scheduled to a later mission and Kepler hopes to have an as yet undetermined number of satellites on SpaceX's Transporter-3 mission in December. Another Canadian satellite, a CubeSat from the University of Toronto Aerospace Team, the Heron MK2, was also scheduled for the Transporter-2 mission via a SpaceFlight contract, but was removed to give the team time to work through a radio licensing issue. Dylan Vogel at UTAT told SpaceQ that they are now looking to fly in Q2 of next year on another SpaceX Transporter mission. SpaceX which early in its existence had ditched launching dedicated missions of small satellites in favour of more lucrative medium to large payloads, has made a renewed effort in recent years to try and capitalize on the burgeoning small satellite market. To that end they created the dedicated Transporter rideshare class of mission with at least two "fixed" windows per year. So when Momentus had to pull out it created a problem. The launch had to go ahead, but could it maximize the launch capacity of the mission. The answer is no. Will SpaceX lose money on the mission? That's unlikely, but we don't know for sure. To its advantage, SpaceX is reusing the first stage booster (B1060) on this mission for the 8th time. On the first SpaceX Transporter mission they did include 10 Starlink satellites. There are none scheduled for this mission. Of the 49 Momentus payloads that had to be removed from the mission, a few were able to find a slot on the mission with other rideshare suppliers. What's on-board One of the fascinating things about these mass rideshare missions, is the sheer number of satellites being launched and the technologies represented. Here's the list of known satellites on the mission. The technologies being launched will be used for IoT, Earth Observation including Synthetic Aperture Radar, communications, propulsion, satellite servicing and various scientific instrumentation.
