FLIR Machine Vision Cameras Capture High-Definition Footage of NASA’s Perseverance Rover Landing on Mars

The Entry, Descent, and Landing (EDL) of the rover may only be a few minutes long, but a lot is going on in those few minutes. Here’s a breakdown of what you’re seeing and from what angle.
After entering the Martian atmosphere, the parachute deploys about 7 miles (11 kilometers) from the surface. Just before this point, three up-looking cameras began recording, capturing footage of the supersonic deployment of the most massive parachute ever sent to space:
Five miles off the ground, the heat shield (used to protect the rover during entry into the Martian atmosphere) drops off and exposes the rover down-look camera, showing some of the rover’s intense ride to Mars’ Jezero Crater:
Then the rover drops away from the back shell (and parachute). From there, its descent is managed by a rocket-powered descent stage called the “SkyCrane.” Here’s a view of the rover captured by a down-looking camera on the SkyCrane:
Then it’s a touchdown! Here’s a view (from a camera on the rover) of the SkyCrane being swept away as the rover touches down on the surface of Mars to begin its mission:
The cameras that captured this footage are FLIR RGB machine vision cameras and include five 1.3-megapixel cameras and one 3.1-megapixel USB camera. “FLIR cameras are designed for operation on Earth, and not built to operate in outer space,” said Sadiq Panjwani, VP of the Integrated Imaging Solutions (IIS) division at FLIR. “So we were quite thrilled that NASA put them to the test.”
NASA began contacting FLIR in 2015 to investigate suitable cameras for the EDL (Entry, Descent Landing) system. Engineers were looking for commercial off-the-shelf (COTS) hardware with an emphasis on low cost and ease of system integration.
This is the first time that FLIR machine vision cameras have been subjected to the extreme temperatures or high gravity forces experienced during the Mars landing. Everyone involved in the engineering and manufacture of cameras at FLIR is thrilled about this testament to their durability and performance. And of course, ecstatic to say that their work has made it to Mars!
Congratulations to the team at NASA and everyone involved in making this historic milestone a reality.
