A Mars 2020 message is seen on the video board of the Nasdaq MarketSite after NASA's Perseverance rover landed on the surface of Mars, Thursday, Feb. 18, 2021 in New York City. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

NASA Deputy Associate Administrator Melanie Saunders and former NASA astronaut Mike Massimino ring the closing bell of the Nasdaq after the NASA's InSight lander successfully touched down on the surface of Mars, Monday, Nov. 26, 2018 at the Nasdaq MarketSite in New York City. The lander sent a signal affirming a completed landing sequence at approximately 3 p.m. EST (noon PST) after touching down on the western side of a flat, smooth expanse of lava called Elysium Planitila. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to study the "inner space" of Mars: its crust, mantle, and core.
