Perseverance Rover

Like the Junocam they tried to kill ingenuity but like the Junocam it proved to be quite useful and valuable.
 
Opposition to Ingenuity

The idea to include a helicopter in the Mars 2020 mission was opposed by several people. Up until the end of the 2010s, several NASA leaders, scientists and JPL employees argued against integrating a helicopter into the mission. For three years, the future Ingenuity was developed outside the Mars 2020 project and its budget.[60][61] And although NASA management accepted assurances in the spring of 2018 that the addition of a helicopter would not harm the goals of the expedition, Mars 2020 chief scientist, Kenneth Farley, stated "I have personally been opposed to it because we are working very hard for efficiencies and spending 30 days working on a technology demonstration does not further those goals directly from the science point of view".[62] Farley was convinced that the helicopter was a distraction from the priority scientific tasks, unacceptable even for a short time.[62]

The skepticism on the part of NASA leadership was not unfounded. Scientists, engineers and managers proceeded from a pragmatic comparison of the benefits of additional aerial reconnaissance with the costs that inevitably fall on the schedule for the rover to complete all the tasks assigned to it. During a live-stream from NASA, MiMi Aung, the Ingenuity Project Manager, and Jennifer Trosper discussed the value of Ingenuity. Trosper argued that the rover would outpace the helicopter due to its auto-navigation capability, thus negating one of central arguments for the value to the mission of the helicopter. During the operations on Mars, Tosper was shown to be correct when, in the spring of 2022, at the beginning of Sol 400 the helicopter fell behind the rover.

There were a number senior management personnel who opposed the Ingenuity helicopter for several reasons, fortunately they were circumvented and Ingenuity's performance on Mars well beyond its' designers expectations proved these opponents wrong.

No, Ingenuity's performance had nothing to do with it. Whether it worked or not had no bearing on the matter. The issue was accommodating the helicopter and the risk it posed to the rover.
 
Ingenuity was kinda cherry on the cake, but the real deal with that mission was a) the rover and b) Mars Sample Return: caching samples.
These two could not be allowed to fail... and even less because of a smallish helicopter drone.

My understanding is that the emplacement of the helicopter below the rover (to be dropped before deployment and flight) could have wrecked the rover if the drop had not happened because of some glitch. End result: the loss a $billion nuclear rover (and a slice of future MSR) to a tiny drone helicopter. That was found to be pretty unacceptable risk.

The helicopter supporters took note of that, and then successfully fought back. In the end everybody was happy: rover worked, did his slice of MSR, while the helicopter flew 72 times rather than 5 planned.

But space exploration history is littered with "no happy ending" failures...

See Ingenuity’s Flight Map: 72 Helicopter Flights on Mars

NASA’s Ingenuity Mars helicopter became the first vehicle to achieve powered, controlled flight on another planet when it took to the Martian skies on April 19, 2021. This video maps the location of the 72 flights that the helicopter took over the course of nearly three years. Ingenuity far surpassed expectations — soaring higher and faster than previously imagined.

Designed to be a technology demonstration that would make no more than five test flights in 30 days, Ingenuity eventually flew more than 14 times farther than the distance expected, and logged more than two hours of total flight time. It flew for the final time on Jan. 18, 2024.

Will Perseverance eventually find microscopic life on Mars now that the SHERLOC instrument has been re activated? I would like to think so.
 
The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed.

Analysis by instruments aboard the rover indicates the rock possesses qualities that fit the definition of a possible indicator of ancient life. The rock exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago when the area being explored by the rover contained running water. Other explanations for the observed features are being considered by the science team, and future research steps will be required to determine whether ancient life is a valid explanation.

Multiple scans of Cheyava Falls by the rover’s SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instrument indicate it contains organic compounds. While such carbon-based molecules are considered the building blocks of life, they also can be formed by non-biological processes.

While both the organic matter and the leopard spots are of great interest, they aren’t the only aspects of the Cheyava Falls rock confounding the science team. They were surprised to find that these veins are filled with millimeter-size crystals of olivine, a mineral that forms from magma. The olivine might be related to rocks that were formed farther up the rim of the river valley and that may have been produced by crystallization of magma.

If so, the team has another question to answer: Could the olivine and sulfate have been introduced to the rock at uninhabitably high temperatures, creating an abiotic chemical reaction that resulted in the leopard spots?

NASA’s Perseverance Rover Scientists Find Intriguing Mars Rock

The discovery provides some wind in the sails for NASA's flagging efforts to devise and fly a Mars Sample Return mission. The agency's most recent plan, costing $11 billion, was determined to be too expensive. Now, the space agency is asking the industry for help. In June it commissioned 10 studies on alternative means of returning rocks from Mars sooner, and presumably for a lower cost.

Now, scientists can point to rocks like Chevaya Falls and say this is precisely why they must be studied in ultra-capable labs back on Earth.

A Striped Surprise​

Last week, team scientists and the internet alike were amazed when Perseverance spotted a black-and-white striped rock unlike any seen on Mars before. Is this a sign of exciting discoveries to come?

Interesting discovery Flyaway, I wonder what is behind the stripes on the rock are? Weathering or something else? But let's see what else Perseverance see's on Mars.
