GREENBELT, Md. — NASA’s Pathfinder Technology Demonstrator 3 (PTD-3) mission, carrying the TeraByte InfraRed Delivery (TBIRD) system, will debut on May 25 as part of SpaceX’s Transporter-5 rideshare launch. TBIRD will showcase the high-data-rate capabilities of laser communications from a CubeSat in low-Earth orbit. At 200 gigabits per second (Gbps), TBIRD will downlink data at the highest optical rate ever achieved by NASA.
