When SpaceX launches a large number of smallsats and payloads on a Falcon 9 launch, as it did on March 5 from Vandenberg in California, it routinely takes several days or even months for the results from each payload or smallsat to trickle in. Two reports today illustrate the growing cottage industry of orbital tugs.
First, a company named Apex has successfuly demonstrated its first service module for satellites, designed to provide the basic services needed for satellites so that companies can focus on designing their primary mission rather than reinventing a basic satellite each time. The module was launched on March 5th, and has been operating as expected. The company hopes to begin mass producing this service module in a new factory later this year.
Second, a new orbital tug company from France, Exotrail, has successfully deployed a cubesat from its first tug. That tug was launched on a Falcon 9 smallsat launch in November, and has been testing operations since. After releasing that cubesat for Airbus’s defense division, the tug is continuing operations, acting as the service module for a second payload from Belgium that is testing its own gyros and reaction wheels for controling smallsat orientation.
These companies are small, and are focused on very specific technologies needed by smallsats to operate efficiently in space. As such, their achievements are generally more mundane and less exciting that a SpaceX Starship/Superheavy test launch, by many magnitudes. Nonetheless, their success, not only technically but financially, suggests a growing maturity to the in-orbit space industry, which will also lay the groundwork for much more sophisticated operations in the future beyond Earth orbit. The people that build these tugs will move on to build vessels that can go to the planets and do things that are presently impossible or too difficult, and do it at low cost and very quickly.
