The names were stenciled by electron beam onto three fingernail-sized silicon chips, along with the essays of the 155 finalists in NASA's "Name the Rover" contest. The chips were then were attached to an aluminium plate on NASA's Perseverance Mars rover at Kennedy Space Center in Florida on 16 March. Scheduled to launch this summer, Perseverance will land at Jezero Crater on 18 February 2021.
The three chips share space on the anodised plate with a laser-etched graphic depicting Earth and Mars joined by the star that gives light to both.
While commemorating the rover that connects the two worlds, the simple illustration also pays tribute to the elegant line art of the plaques aboard the Pioneer spacecraft and golden records carried by Voyagers 1 and 2. Affixed to the center of the rover's aft crossbeam, the plate will be visible to cameras on Perseverance's mast.

Currently, the coronavirus has not impacted the Mars Perseverance rover launch schedule. The installation was one of numerous recent activities performed by the Perseverance assembly, test and launch operations team.
On 21 March, the team began reconfiguring the rover so it can ride atop the Atlas V rocket. Steps included stowing the robotic arm, lowering and locking in place the remote sensing mast and high-gain antenna, and retracting its legs and wheels.
The Perseverance rover is a robotic scientist weighing just under 1,043 kilograms. It will search for signs of past microbial life, characterise Mars' climate and geology, collect samples for future return to Earth, and help pave the way for human exploration of the Red Planet.
JPL, a division of Caltech in Pasadena, is building and will manage operations of the Mars Perseverance rover for NASA. The agency's Launch Services Program, based at the agency's Kennedy Space Center in Florida, is responsible for launch management.
