Pathfinder-4

Lightweight Integrated Solar Array And Antenna (LISA-T) payloads

Pathfinder Technology Demonstrator 4

PTD-4, a 6U CubeSat designed to set to test a new solar panel system developed by NASA’s Marshall Space Flight Center, the Lightweight Integrated Solar Array and Antenna (LISA-T). This multi-functional system, called LISA-T, is special because it’s not only lightweight but can also unfold in space to reveal a large solar panel with a built-in antenna. The mission will assess solar panel deployment, power generation, and antenna performance between the Earth and the vehicle.

Scalable from 100 to 500 watts, with potential for even higher power outputs, LISA-T is ideal for deep space missions using small spacecraft. Its thin-film technology offers significant advantages over traditional solar arrays, including reduced weight, smaller stowed size, and a power-to-mass ratio three times higher.

The multiple, planned PTD missions will demonstrate and validate new and novel subsystem technologies that can be scaled and utilized on a wide range of future science and exploration missions.
