This experimental payload is known as IRIS (Internet Routing in Space) demonstration.

TacSat-1 will carry a variety of experimental payloads.

The Space Radiation Monitor, the secondary and experimental payload, is capable of measuring the total ionizing dose from the charged particles at the orbits of satellites.

All such experimental payloads were under the general responsibility of MSFC.

Air bags, polystyrene pellets, and magnetic or mechanical brakes are sometimes used to arrest the fall of the experimental payload.

It has a number of secondary experimental payloads on board:

The experimental payloads will be recovered after the flight, which will also minimize costs for the payload developer.

Two-thirds of the 75 experimental payloads aboard Discovery require some sort of crew attention in space.

Some scientists disagreed about how the experimental payloads should be sent to Mars.

The rocket and all its experimental payload were a complete loss.
