Mars mission: These three different types of cutting edge lenses will contribute to the success of NASA’s Rover "Perseverance"

A journey into space requires unique demands. Our engineers developed special lenses for the Mars 2020 mission.

Pioneers are the first to explore new territory. Our images of pioneers can be at opposite ends of the technological spectrum – from weather-beaten frontiersmen in dust-covered wagons to imaginative scientists in bright, sterile labs. However, few endeavors embody the pioneering spirit as much as NASA’s missions into space. And like the Apollo program, the public’s imagination has been captured by the quest for the exploration of Mars.

The next Mars mission is scheduled for launch in July 2020, when Earth and the Red Planet are relatively close to one another. Central to this expedition is a new robotic exploration vehicle, the Mars 2020 Rover named Perseverance.

Based on NASA’s successful Curiosity Rover platform, the Perseverance Rover will search for historical signs of life and begin preparations for possible human colonization. At approximately 10 feet long and 7 feet tall, the 2020 Rover is about the size of an SUV. At just 2,000 pounds it is considerably lighter. It has an improved wheel design, its long-range mobility system will allow it to travel up to 13 miles on the Martian surface and an exciting new addition to its capabilities is a drill capable of penetrating rocks.

Three Extraordinary Engineering Lens Assemblies were developed for the Mars mission

To reduce cost, time and risk Perseverance utilizes about 85% of “heritage hardware” from the Mars Science Laboratory’s (MLS) Curiosity Rover. Among the new improvements, at the heart of this remarkable vehicle – guiding it, protecting it and enabling the collection of samples - are the Enhanced Engineering Cameras (EECAMs) with three new types of lens assemblies developed by Jenoptik in Jupiter, Florida.

Mars Mission 2020: three types of lens assemblies

  1. Two sets of stereo NavCams lenses, or navigation lenses, will capture the first live video footage from the mission and continue to transmit as the rover explores the surface. Mounted high on the mast, they will enable remote operators to see where the rover is going, plus they’ll play a crucial role when the rover drives autonomously. Capable of distinguishing objects as small as a golf ball at a distance of 80 feet, they will ensure the vehicle chooses a safe course.

  2. The HazCams lenses, or hazard avoidance lenses, will also provide stereo images, will recognize boulders, holes and other potential obstacles such as sand dunes or trenches. There are 6 in total – two mounted on the back of the vehicle and four on the front. The front-mounted HazCams will serve a dual purpose. They will help the rover identify obstacles and allow engineers to see the movement of the robotic arm during sample collection.

  3. Mounted within the Rover’s belly, the CacheCam lenses will guide the collection and storage of the rock and soil samples as well as keeping photographic records of the sample gathering process. In addition to conducting physical and chemical analysis, the rover – with the aid of the Cache Cam – will pack samples into tubes and place them in a designated storage area on the planet’s surface. Future missions could potentially transport these samples to Earth for more detailed examination.

All three lens types play a critical role in the Mars mission’s four key scientific goals:

  1. Assess the Martian Climate
  2. Conduct a geological study
  3. Prepare for manned expeditions
  4. Determine whether there was ever life on Mars

As a pioneer of optical technologies whose origins date back to Carl Zeiss and Ernst Abbe, Jenoptik is helping pave the way for possible human exploration of Mars by engineering and manufacturing mission-critical technologies for space exploration. From helping Perseverance navigate, avoid hazards while in motion and enabling the collection of samples, Jenoptik is at the forefront of delivering critical photonic technologies and products for human advancement.

The entire Jenoptik team is proud of the extraordinary lenses that will be roaming the Red Planet on the Perseverance Rover which were developed, assembled and tested at our facilities. With a long history of meeting extreme environments and mission critical performance requirements for applications including space exploration we are also proud to contribute to the knowledge of the Mars environment as well as ignite the imaginations of future scientists, engineers and innovators everywhere.
