Want to know about NASA’s most advanced life-hunting robot on Mars? Well, here are some updates.
On the 30th Martian day of the mission, i.e. on 21st March 2021,
the Perseverance rover released the debris shield that protects the ingenuity
helicopter while landing. This helps the helicopter to rotate downwards and get
out of the rover. This happened when a cable was cut by a pyrotechnic device.
Some Responsibilities
- The operations of ingenuity and Perseverance are built as well as managed by NASA’s Jet Propulsion Laboratory(JPL).
- NASA’s JPL is managed by Caltech located in California’s Pasadena.
- Malin Space Science Systems(MSSS) located in San Diego built a Wide Angle
Topographic Sensor for Operations and Engineering(WATSON) camera.
MSSS and JPL jointly operate the WATSON. WATSON located at the end of the arm
of the rover’s robot took an image on the Scanning Habitable
Environments with Raman and Luminescence for Organics and Chemicals(SHERLOC) instrument.
- The NASA Space Technology Mission Directorate(STMD), the NASA's Science Mission Directorate(SMD), and the NASA Aeronautics Research Mission Directorate(ARMD) support the demonstration activity of the Mars helicopter technology.
- We know that the main aim of the Perseverance rover is ‘astrobiology.’ Subsequently, these sealed samples will be collected and sent back to the Earth by the spacecraft. NASA will do this along with European Space Agency(ESA).
Some Motives Of The Perseverance Rover
- The main motive is to collect promising pieces of evidence of life on Mars.
- To convert the carbon dioxide in the atmosphere into oxygen would be helpful for further manned missions.
- Making the helicopter fly.
- Clicking images.
After Dropping The Helicopter
Ingenuity was depending on the Perseverance’s power system for
its survival. But now, to avoid the freezing and cracking of its unshielded
electronic components during the challenging Martian night, it will have to run
an important heater using its battery. The temperature during a tough Martian
night can drop to -1300 F (-900 C). But the interior of the helicopter can be
maintained at 450 F (70 C).

Historic Selfie On Mars
This cannot be compared with the regular selfies we take as this
selfie was taken about 362 million kilometers away from the earth. This
historic selfie was taken by the rover on 6 April 2021. But this was a bit
tricky and challenging. A 9 feet wide Perseverance along with the little
ingenuity helicopter had to be present in the selfie on the Martian surface. The video shared by
NASA’s JPL includes the sound of the twists and careful movements of the
rover’s robotic arm to take 62 individual images. These images were clicked
with the help of WATSON and then stitched together by the MSSS image processing
engineers on Earth to make it look like a normal image. All these images were
clicked for over an hour.
When the images arrived on Earth, they had to clean the
blemishes caused by the dust on the light detector of WATSON. Then they had to
eliminate the joins to smoothen the image using software before finally warping
the whole stuff into a single selfie.
62 images had to be clicked separately because the WATSON camera
has been made to help in the scientific research by capturing close-up detailed
images. It took over one week to plan an event of sending sequences and
commands to the rover for moving its arm. Getting the ingenuity at the correct place
was important too.
Such selfies help the scientists to check the wear and tear
present on the rover. This work has been done beautifully as the
mountain-like-looking elevations in the background and the prints of the
rover’s wheels on the surface can be seen clearly.
Special software was created by JPL to keep the Perseverance’s
arm from colliding with the rover. Arm’s trajectory had to be adjusted every
time a collision was detected on Earth in simulations. This had to be done
several times to ensure the safety of the arm’s motion. However, the main
motive was to keep the robotic arm closer to the rover’s body.
Mastcam-Z
Perseverance rover has a primary science camera named ‘Mastcam-Z.’ But
the main objective of making it was to examine the soil samples closely. Thus,
its selfie range is not wide enough.
Martian Dust Storm
This video depicts
the small dust cloud registered on 23 June 2021.
Conclusion
NASA had released the sounds of the wheels of the Perseverance
rover fractioning against the Martian surface. Though it was much advanced and
clear, it received some criticism. This time, a lot of remarkable work like
providing a historic selfie, registering a dust storm, collecting
life-evidences, and releasing the mini-copter done by Percy is mentioned in
this post.
