According to NASA’s Perseverance rover, ancient rocks in Jezero Crater formed in the presence of water. These sedimentary rocks are more than 3.5 billion years old and may predate the appearance of life on Earth. When and if these samples are returned to Earth, scientists hope to determine if they hold evidence of ancient Martian life.

NASA’s Perseverance Rover has left Mount Washburn behind and arrived at its next destination, Bright Angel. It found an unusual type of rock there that scientists are calling ‘popcorn rock.’ The odd rock is more evidence that water was once present in Jezero Crater.

In 2021, NASA’s Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected to reveal much about Mars’ past and how it transitioned from being a warmer, wetter place to the frigid and desiccated place we know today. Unfortunately, budget cuts have placed the future of the proposed NASA-ESA Mars Sample Return (MSR) mission in doubt.
As a result, NASA recently announced that it was seeking proposals for more cost-effective and rapid methods of bringing the samples home. This will consist of three studies by NASA and the Johns Hopkins University Applied Physics Laboratory (JHUAPL). In addition, NASA has selected seven commercial partners for firm-fixed-price contracts for up to $1.5 million to conduct their own 90-day studies. Once complete, NASA will consider which proposals to integrate into the MSR mission architecture.

I can remember when Perseverance was launched, travelled out into the Solar System and landed on Mars in February 2021. In all the time since it arrived, having clocked up 1000 days of exploration, it has collected 23 samples from different geological areas within the Jezero Crater. The area was once home to an ancient lake and if there is anywhere on Mars to find evidence of ancient (fossilised) life, it is here.

I really can’t believe that the Ingenuity helicopter on Mars took its maiden voyage in April 2021. On the 16th April 2024, engineers at NASA have received the final batch of data from the craft which marks the final task of the team. Ingenuity’s work is not over though as it will remain on the surface collecting data. For the engineers at NASA, they have their sights set on Dragonfly, a new helicopter destined for Titan.

If there’s a Holy Grail on Mars, it’s probably a specific type of rock: A rock so important that it holds convincing clues to Mars’ ancient habitability.
Perseverance might have just found it.

As if the Mars Perseverance Rover and Ingenuity Drone were not exciting enough then the next step in this audacious mission takes it to a whole new level. Mars Sample Return Mission is to follow along, collect and return the samples collected by Perseverance back to Earth. However the status of Mars Sample Return is uncertain as engineers are still working on technology to retrieve the samples. The current challenge is the gripper arm that will collect the samples and stow them safely and securely before transportation without damaging them.

Ingenuity has been the first aerial vehicle on another world. NASA announced the end of the Martian helicopter’s life at the end of its 72nd flight. During the flight there had been a problem on landing and, following the incident a few photos revealed chips in one of the rotor blades but nothing too serious. New images have been revealed that show the craft is missing one of its rotor blades entirely!

There’s a problem with the Perseverance rover. One of its instruments, the laser-shooting SHERLOC, which is mounted on the end of the robotic arm, has a dust cover that is supposed to protect the instrument when it’s not in use. Unfortunately, the cover has been stuck open, and that can allow dust to collect on the sensitive optics. The cover is partially open, so the rover can’t use its laser on rock targets or collect mineral spectroscopy data. NASA engineers are investigating the problem and are hoping to devise a solution.

The search for life on alien worlds has captivated us for hundreds of years. In some respect, the search for life has expanded to the search for water since it is not unreasonable to assume if there is water then there is a good chance there is life too. When NASA selected the landing site for Perseverance, they were looking for such a body of water and settled upon the Jezero Crater. Images from orbiters reveal a crater that looks like it has been filled with water in the past but further investigations were needed to confirm. Now it seems, Perseverance has risen to the challenge.
