<Li> Centro de Astrobiología (CAB) </Li> <Li> Centrum Badan Kosmicznych (CBK) </Li> <P> As part of its public outreach, NASA organized a program where members of the public were able to have their names sent to Mars aboard InSight . Due to its launch delay, two rounds of sign - ups were conducted totaling 2.4 million names: 826,923 names were registered in 2015 and a further 1.6 million names were added in 2017 . An electron beam was used to etch letters only ​ ⁄ the width of a human hair onto 8 mm (0.3 in) silicon wafers . The first chip was installed on the lander in November 2015 and the second on 23 January 2018 . </P> <P> 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 during the probe's entry, descent and landing (EDL) phase . The two 6U CubeSats, named "MarCO" A and B, are identical . They measure 30 cm × 20 cm × 10 cm (11.8 in × 7.9 in × 3.9 in) and are flying as a pair for redundancy . They will not enter orbit but fly past Mars during the EDL phase of the mission and relay InSight's telemetry in real time . MarCO is a technology capability demonstration of a communications relay system . </P>
