On February 18th, NASA successfully landed the Perseverance Rover on Mars. This historic event marked more than just another touchdown; it was the first time that the entire entry, descent, and landing sequence of a spacecraft was captured and broadcasted live for public viewing. For decades, engineers had meticulously planned every step of the rover’s arrival on the Red Planet, but this mission offered unprecedented transparency into their work.

Using six FLIR machine vision cameras positioned to capture multiple angles, NASA documented each thrilling phase of the descent in real-time. Though only a few minutes long, this footage provided invaluable data for engineers to assess system performance and inspired millions worldwide with its raw beauty.

What You Saw, Explained

The EDL sequence—often referred to as the “seven minutes of terror”—contained multiple critical phases:

  1. Parachute Deployment
    Upon entering the Martian atmosphere at supersonic speeds, a massive parachute deployed approximately seven miles (11 kilometers) above the surface. Three up-looking cameras captured footage just before this deployment, documenting the most intense phase of braking.

  2. Heat Shield Separation
    At five miles altitude, the heat shield—which protected the rover during atmospheric entry—detached, exposing a down-look camera for the first view of the descent stage and rover’s journey toward Jezero Crater.

  3. SkyCrane Maneuver
    The rover separated from its back shell and was lowered by a rocket-powered descent stage called SkyCrane. A down-looking camera on this platform provided critical telemetry as it guided the rover to a precise landing spot.

  4. Touchdown Sequence
    Finally, the rover touched down while still attached to the SkyCrane, which then executed a controlled ascent away from the vehicle. This was captured by cameras mounted directly on the rover for the first time ever.

The Technology Behind the Scenes

The cameras used in this groundbreaking broadcast were FLIR RGB machine vision systems—specifically five 1.3-megapixel models and one USB-connected 3.1-megapixel camera—not typically designed for space applications. “We built our cameras for Earth-based use, not outer space,” said Sadiq Panjwani of FLIR’s Integrated Imaging Solutions division. Yet NASA selected these systems because they met the mission requirements for reliability and ease of integration.

This was a first-of-its-kind test for commercial off-the-shelf hardware in Mars landing conditions—extreme temperatures combined with high gravitational forces during descent. The success demonstrated both durability and performance capabilities, proving that robust imaging solutions exist even outside Earth’s controlled environments.

Honoring the Engineers

Behind every successful mission are hundreds of engineers working tirelessly to make history possible. This EDL broadcast marked not just a milestone for NASA but also validation for the companies providing critical technology like FLIR. It was an emotional moment for everyone involved in building and supporting these cameras—knowing their work traveled millions of miles across space.

Congratulations go out to every person who contributed to this historic achievement, from mission control engineers to camera designers. Their combined efforts made it possible for the entire world to witness a landing on Mars unfold live for the first time ever.

This is just one step in humanity’s journey toward interplanetary exploration—and FLIR will undoubtedly continue playing its part.
