Starfish – Behind The Black

NASA awards small study contract to orbital tug company Starfish Space

Capitalism in space: NASA has awarded a small three-month study contract to the U.S. orbital tug company Starfish Space, to consider using its Otter orbital tug to rendezvous and inspect defunct orbital debris.

The award amount was not released, suggesting this is a very small contract designed simply to see if the company’s technology warrants a larger contract.

Some of those features — including Starfish’s Cetacean relative navigation software and its Cephalopod autonomous guidance software — could be tested sometime in the next few months on the company’s Otter Pup prototype spacecraft, which was sent into orbit in June but was forced into an unfortunate spin during deployment. Starfish stabilized the spin in August and is currently making sure that all of Otter Pup’s systems are in working order for future tests.

NASA’s follow-up contract, awarded through the space agency’s Small Business Innovation Research program, or SBIR, calls for Starfish to assess the feasibility of using its full-scale Otter satellite servicing vehicle to rendezvous with large pieces of space debris and inspect them.

This contract is comparable in goals to the one NASA issued to Astroscale earlier this week, though much smaller.

Startup orbital tug company experiences technical issues on demo flight

The first test rendezvous and docking of two smallsats built by the startup orbital tug company Starfish Space and space station startup Launcher/Vast are facing significant technical issues because both spacecraft are spinning in an unexpected manner.

Soon after Orbiter SN3 separated from the Falcon 9 upper stage, it experienced an anomaly that set it spinning at a rate on the order of one revolution per second, far outside the bounds of normal operating conditions.

By the time Launcher’s team made contact with Orbiter, fuel and power levels were critically low — and the team made an emergency decision to deploy Otter Pup immediately. In a joint statement issued today, Launcher and Starfish Space said that quick action “gave the Otter Pup mission a chance to continue.”

With assistance from Astro Digital and ground station partners, Starfish’s team contacted Otter Pup and determined that it was generating power — but was also spinning because of the circumstances of its emergency deployment.

The plan had been to deploy Otter Pup and have it rendezvous and then dock with Orbiter, demonstrating the maneuverability of both spacecraft as well as their docking equipment. The spinning now threatens the company’s ability to do this. Over the next few months engineers will make attempts to slow the spinning of Orbiter, but it is unlikely a docking can now be attempted.

Another orbital tug & servicing company raises investment capital

Starfish Space, a new entrant into the orbital tug & servicing industry, has successfully raised $14 million in new investment capital, in addition to the $7 million it had raised in a previous fund-raising round.

The company hopes to launch a test satellite later this year, dubbed Otter Pup, which will undock from the orbital tub of another company, Launcher Space, do maneuvers, and then redock.

Starfish’s plan calls for Otter Pup to be sent into orbit this summer as a rideshare payload on SpaceX’s Transporter-8 mission. The spacecraft will be deployed from Launcher Space’s Orbiter space tug, and then will execute a series of maneuvers with a xenon-fueled electric propulsion system to move away from the tug.

If all goes well, the Otter Pup will return to the vicinity of the Orbiter, and then use an electrostatic-based capture mechanism to latch onto a docking target on the space tug. It could take months to test out the Otter Pup’s systems and tweak them as necessary for its test hookups.

Though the company says it will offer tug services once operational, it appears it is mostly aiming for the satellite robotic servicing market. It, like Astroscale, has developed its own docking capture device, which it will try to convince satellite companies to attach to their satellites. It will then use this to dock and service those satellites. Since these capture devices are proprietary, the number that each company gets onboard satellites will determine that company’s future sales.

This orbital servicing industry appears to be growing very quickly, now that launch costs have come down by about 90% since the arrival of SpaceX. For example, the orbital tug company Momentus is getting ready to launch its third mission.
