lander's robotic arm through the mole-rescue efforts that used the arm in ways that were unplanned before the mission. MarCO spacecraft The Mars Cube One (MarCO) spacecraft are a pair of 6U CubeSats that piggybacked with the InSight mission to test CubeSat navigation and endurance in deep space, and to help relay real-time communications (with an eight-minute lightspeed delay) during the probe's entry, descent and landing (EDL) phase. The two 6U CubeSats, named MarCO A and B, are identical. They were launched along with InSight, but separated soon after reaching space, and they flew as a pair for redundancy while flanking the lander. They did not enter orbit, but flew past Mars during the EDL phase of the mission and relayed InSight telemetry in real time. The success of the MarCO spacecraft proved the viability of the cubesat platform for deep space missions and helped serve as a technical demonstration for potential future missions of a similar nature. On 5 February 2019, NASA reported that the CubeSats went silent, and are unlikely to be heard from again. Mass: each. Dimensions: each Each has a reflectarray high gain antenna Miniaturized radio operating in UHF (receive only) and X-band (receive and transmit). They carry a miniature wide-angle camera. Cold gas thrusters for attitude adjustments. Star tracker for navigation. Team and participation The InSight science and engineering team includes scientists and engineers from many disciplines, countries and organizations. The science team assigned to InSight includes scientists from institutions in the U.S., France, Germany, Austria, Belgium, Canada, Japan, Switzerland, Spain, Poland and the United Kingdom. Mars Exploration Rover project scientist W. Bruce Banerdt is the principal investigator for the InSight mission and the lead scientist for the SEIS instrument. Suzanne Smrekar, whose research focuses on the thermal evolution of planets and who has done extensive testing and development on instruments designed to measure the thermal properties and heat flow on other planets, is the lead for InSight HP3 instrument. The Principal Investigator for RISE is William Folkner at JPL. The SEIS Instrument PI is Philippe Lognonné of IPGP, and the HP3 Instrument PI is Tilman Spohn of the DLR Institute of Planetary Research. The InSight mission team also includes project manager Tom Hoffman and deputy project manager Henry Stone. Major contributing agencies and institutions are: National Aeronautics and Space Administration (NASA) Centre National d'Études Spatiales (CNES) German Aerospace Center (DLR) Italian Space Agency (ASI)
