New York City's most famous building turned red overnight to celebrate NASA's Perseverance rover landing today (Feb. 18).
"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 said in the statement.

Perseverance will be a link in NASA's hopes to eventually bring samples of Mars back to Earth, although that future mission depends on funding, political will and ongoing international discussions (the sample-return mission so far includes the European Space Agency).
If all goes to plan, sample return could kick off in the late 2020s. Human Mars exploration will begin no earlier than 2035, according to NASA's long-term plans as of 2019, but the timeline again depends on budget and priorities.
The famed New York City steel structure, which completed construction in 1931, wasn't the only United States building lit up in Mars-themed regalia for Perseverance. The Los Angeles International Airport gateway pylons will glow red through sunrise Friday (Feb. 19), according to NASA's Jet Propulsion Laboratory (JPL), and you can see a picture of the pylons on the NASA Perseverance Twitter feed. JPL, where rover operations are centered, is located in nearby Pasadena.

In Ohio, Terminal Tower in Cleveland also went ruddy in honor of the Red Planet, according to a tweet from the NASA Glenn Research Center (Glenn is also based in Cleveland). Chicago's Adler Planetarium will turn red "all week long" in honor of Perseverance, the museum said in a tweet showing the otherworldly glow peeking through all the windows.
