How Perseverance will collect samples

When NASA's Mars 2020 rover lands on the Red Planet today, it will seek signs of past microbial life and characterize the planet's climate and geology. It is the first rover ever to carry a drill for coring samples from Martian rocks and soil. This series of animations shows how those precious samples will be safely stowed on Mars for potential future pickup and return to Earth by another mission.

Helicopter Flight Testing

After mission controllers have determined that rover systems are functioning as desired, Perseverance will find a flat area to serve as a helipad for the Ingenuity Mars Helicopter technology demonstration. In the first months after landing, if all goes well, the rover will deploy Ingenuity in the center of this area and drive a safe distance (about 100 meters) away from it. The helicopter’s team will then have up to 30 sols to perform a series of flight tests on Mars, the first time powered, controlled flight has been attempted on another planet.

The rover's Mastcam-Z and Navigation Cameras will collect still images of Ingenuity – and possibly a video or two. The two microphones (one located on the SuperCam instrument; the other, on its chassis) will attempt to pick up the sounds of the flight operations.

Ingenuity

NASA’s Ingenuity Mars Helicopter is the first aircraft humanity has sent to another planet to attempt powered, controlled flight. If its experimental flight test program succeeds, the data returned could benefit future explorations of the Red Planet – including those by astronauts – by adding the aerial dimension, which is not available today.

Ingenuity weighs about 1.8kg on Earth and about 0.68kg on Mars. It features four specially made carbon fiber blades arranged into two 1.2-meter-long counter-rotating rotors that spin at roughly 2,400 rpm. A solar array on top of the rotor system charges six lithium-ion batteries. The drone also has two cameras: One color with a horizon-facing view for terrain images and one black-and-white
for navigation.

Mars 2020: End of a Journey

After nearly 300 million miles (470 million km), NASA’s Perseverance rover completes its journey to Mars today. But, to reach the surface of the Red Planet, it has to survive the harrowing final phase known as Entry, Descent, and Landing.

Live coverage by NASA will begin at 19:15 UTC (in just over an hour) and Perseverance will enter the atmosphere at 20:48 UTC.
