Tukwila, Wash.-based Starfish Space and California-based Impulse Space say they’ve successfully demonstrated an in-space satellite rendezvous during a mission that handed over control of an Impulse Mira spacecraft to Starfish’s guidance and navigation system.
The demonstration was code-named Remora, in honor of a fish that attaches itself to other marine animals. Operation Remora was added to Mira’s agenda for Impulse Space’s LEO Express 2 mission, which was launched in January. Impulse and Starfish waited until the Mira spacecraft completed its primary satellite deployment tasks for LEO Express 2. Then they spent several weeks monitoring the maneuvers for Remora.
“About a month ago, we concluded the major steps here,” Starfish co-founder Trevor Bennett told me. “Since then, we’ve been getting data down and understanding the full story. And the full story is incredible.”
Remora was kept under wraps until today, primarily because both companies wanted to make sure that the demonstration actually worked as planned. “There was never a guarantee that there would be an outcome here,” Bennett explained. “And so what we wanted to do is talk about it when there was something to talk about.”
Bennett said the demonstration showed that Starfish’s software suite for guidance, navigation and control could be used on a different company’s satellite to make an autonomous approach to another spacecraft in orbit.
“Remora became definitely a first for us, in terms of being able to allow a whole new vehicle platform to autonomously do this full mission, all the way in and through,” he said. “Basically, we had no operator commands necessary for the vehicle to fly itself all the way down to 1,200 meters, take a bunch of pictures and then autonomously egress back out to further distances.”
