NASA Shares First-Person View of Mars Landing

The National Aeronautics and Space Administration (NASA) has published video footage obtained by the Perseverance landing module and rover, presenting the renowned “seven minutes of terror” from a compelling first-person viewpoint. The imagery transmitted on Friday served as a preview; this represents the complete experience, and constitutes the inaugural video recording of a Mars landing ever achieved.

Descent and Landing Overview

A comprehensive account of the rover’s descent and overall mission is available online, but in brief, the sequence unfolded as follows:

Initially, the spacecraft decelerated from its interplanetary velocity as it entered the Martian atmosphere. Subsequently, the heat shield was released, and the parachute was deployed. Located beneath the heat shield were several cameras and instruments designed to analyze the terrain and identify a suitable landing location.

At a specific altitude and velocity, the parachute was detached, and the “jetpack” lower stage assumed control, utilizing rockets for precise maneuvering toward the designated landing zone. Approximately 70 feet above the surface, the “sky crane” system lowered the rover gently to the ground, after which the jetpack detached and flew to a safe distance for a controlled crash.

The entire procedure spans roughly seven minutes, with the final seconds proving particularly intense.

Previous Mars rovers transmitted telemetry data and some imagery, but this degree of visual documentation is unprecedented. Even the Insight lander, launched in 2018, lacked the capability to relay this type of footage.

A New Perspective on Martian Landings

“This marks the first instance where we’ve been able to capture an event like a spacecraft landing on Mars,” stated Mike Watkins, head of JPL, during a press conference. “These videos are truly remarkable; we all reviewed them extensively over the weekend. We anticipate gaining valuable insights by analyzing the vehicle’s performance in these videos, but a significant goal is to share this journey with the public.”

The team emphasized the entry, descent, and landing (EDL) camera system, which was engineered both to monitor the process and to deliver the immersive experience desired by the entire team.

“Personally, I doubt I’ll ever pilot a spacecraft down to the surface of Mars,” commented Matt Wallace, deputy project manager of Perseverance at JPL. “However, viewing this imagery will provide a sense of what it’s like to successfully land in Jezero Crater with Perseverance.”

Cameras were positioned facing upwards on the capsule, jetpack, and rover, and downwards on the latter two, capturing footage in both directions throughout the majority of the process. The image of the heat shield separating is already considered iconic, revealing the Martian landscape in a manner reminiscent of footage from the Apollo lunar landings:

The complete video can be viewed below:

More than 30 gigabytes of imagery were recorded during the descent, despite one camera malfunctioning upon parachute deployment. Data transmission, utilizing Mars orbiters, is initially slow—approximately a 2 megabit connection—but gradually increases to higher speeds.

Each frame of the video offers new data regarding the Mars landing process. For example, one of the springs used to eject the heat shield was observed to have disconnected, though this did not impact the mission. All footage is being meticulously analyzed for further insights.

Additional Data from Perseverance

Alongside these landing videos, Perseverance has transmitted several full-color images captured by its navigation cameras, although not all systems are fully operational yet. The team combined the initial images of Perseverance inspecting itself and its surroundings to create this panoramic view:

Further images will be released as the team processes and uploads them.

First Sounds from Mars

As a final offering, the team released the first-ever audio recording from the surface of Mars, hoping it would provide new insights and allow those unable to view the images to experience the landing in a different way.

The EDL system included a microphone intended to capture the sound of the landing, but it did not function during the descent. However, it is now operating flawlessly on the surface and has recorded the ambient sounds of the red planet. While the sound of wind may not seem particularly unusual, it is remarkable to realize that this is wind blowing across another world.
