Pathfinder Risk Reduction [Tyvak]
The Pathfinder Risk Reduction, also known by the manufacturers designation Tyvak 0129, is a 6U CubeSat technology demonstration mission funded and built by Tyvak, that serves as a risk reduction for NASA's PTD missions.
Tyvak-0129 seeks to gather in-flight data for the bus hardware platform as a risk reduction prior to the NASA Pathfinder mission. The Tyvak-0129 bus platform includes the next generation of Tyvak power, communication, GNC and on-board processing subsystems and will be identical in form, fit and function to the bus used on NASA Pathfinder. Subsequently, Tyvak-0129 will serve as a flight demonstration to reduce risk and provide flight heritage to the bus platform prior to the launch of the NASA Pathfinder (PTD) experimental missions later in 2019.
In addition, Tyvak-0129 hosts two experimental payloads to increase their technology readiness level and gather valuable flight test data. The two payloads are an electric propulsion system developed by Accion Systems Inc and a receive-only radio system developed by the Lockheed Martin Corporation. Both payloads are only powered by Tyvak-0129 and rely on the spacecraft bus to downlink all flight telemetry to ground assets.
Lockheed Martin's Pony Express 1 payload, an example of rapid prototyping, was developed, built and integrated in nine months, and was funded completely by Lockheed Martin Research and Development funding. This orbital proving ground is validating payload hardware and software, and is packed with new technology that fits into a satellite the size of a shoebox. Some of the key technologies being flight-tested include:
It was launched by a launch arranged via Tyvak on an Indian PSLV-QL rocket.
