Test a deployable conductive tape by Tethers Unlimited for deorbiting.
Test a Terminator Tape device developed by Tethers Unlimited. The Terminator Tape is a thin extendable tether designed to generate aerodynamic drag to accelerate the re-entry of small satellites, helping to prevent the creation of space junk.
Spacecraft will be built on the Raptor satellite bus, based on a 12U CubeSat form factor. The Dragracer satellite will split into two nearly identical pieces after launch. One half of the spacecraft carries the Terminator Tape, and the other does not, allowing engineers to compare how their altitudes change over time.
After a few days in space, the tether will extend to a length of about 820 feet (250 meters). The tape measures about 1.5 to 2 inches wide. Gravity gradient forces will pull the tether in a vertical orientation, stabilizing the satellite’s attitude and increasing drag. A preflight analysis predicts the Terminator Tape will allow the spacecraft with the tether to re-enter the atmosphere and burn up within two-to-four weeks, while the other satellite — acting as a control in the experiment — is expected to re-enter in eight-to-12 months.
