Watch NASAs Perseverance Rover Land Video from Mars

NASA has been actively involved in several Mars missions. Since there may have been developments after that time, I'll provide an overview of some of the key missions up to that point:

Mars Rovers:

Curiosity Rover: NASA's Curiosity rover, also known as the Mars Science Laboratory, landed on Mars in August 2012. It continues to explore the Gale Crater and has made significant discoveries about the planet's geological history and potential habitability.

Perseverance Rover: NASA's Perseverance rover, which landed on Mars in February 2021, is the most recent Mars rover. Its mission includes searching for signs of past microbial life, collecting and preserving samples for future return to Earth, and testing new technologies for future missions.

InSight Mission:

The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission, which landed on Mars in November 2018, is a stationary lander designed to study the interior of Mars. It has instruments to measure seismic activity, heat flow, and the planet's wobble to better understand its internal structure.
Mars Reconnaissance Orbiter (MRO):

Launched in 2005, the Mars Reconnaissance Orbiter is an ongoing mission that studies the Martian atmosphere, surface, and subsurface. It has provided valuable data for selecting landing sites for other missions and monitoring the planet's changing climate.
MAVEN Mission:

The Mars Atmosphere and Volatile Evolution (MAVEN) mission, launched in 2013, is focused on studying the Martian atmosphere to understand how and why it has changed over time.
Mars Sample Return (Planned):

NASA has been working on a mission to return Martian samples to Earth in collaboration with the European Space Agency (ESA). This mission aims to collect samples from the Martian surface, store them, and then return them to Earth for in-depth analysis. It is planned for the future.
Please note that since my last update was in September 2021, there may have been new developments in NASA's Mars exploration missions. I recommend checking the latest information from NASA or other reliable sources for the most up-to-date details on Mars missions and discoveries.
