At 3:54:26 PM EST on 18 February 2021, NASA received confirmation that the Mars 2020 mission had successfully landed the Perseverance rover and the Ingenuity helicopter on Mars, the event having taken place 11 minutes 22 seconds earlier. (The delay was due to the speed of light, and the time it took radio signals to travel from Mars to Earth.)

The Perseverance rover plaque on this display at the Kennedy Space Center Visitor Complex on Merritt Island, Florida, reads:

The Mars 2020 rover will study an area on Mars to find signs of past microbial life. It will drill into these rocks, take core samples, enclose them in sealed tubes, and leave them on the Martian surface so that a later Mars mission could potentially return them to Earth for full laboratory analysis.

The Ingenuity helicopter plaque reads:

This is a technology demonstration to test powered flight on another world for the first time. The Mars Helicopter working with a rover could help future missions on Mars by using aerial mobility to scout points of interest, helping engineers back on Earth plan driving routes.

The back end of the Curiosity rover replica in the adjacent display can be seen at the right edge of the picture.
