Grabbing Samples from the Surface of Mars

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.

ExoMars is Back on Track for Mars in 2028

The ExoMars Rover mission is back on track for its mission to Mars, but Russia won’t be a part of it this time. Following Russia’s disastrous invasion of neighbouring Ukraine in February 2022, the ESA suspended the ExoMars program.

Now, the mission is targeted for a 2028 launch to Mars without Russian involvement. In anticipation of that launch date, the ESA is busy testing the Rosalind Franklin rover and its mission-defining drill.

How are Mars Rocks Getting “Shocked” by Meteorite Impacts?

On Mars, NASA’s Perseverance rover is busy collecting rock samples that will be retrieved and brought back to Earth by the Mars Sample Return (MSR) mission. This will be the first sample-return mission from Mars, allowing scientists to analyze Martian rocks directly using instruments and equipment too large and cumbersome to send to Mars. To this end, scientists want to ensure that Perseverance collects samples that satisfy two major science goals – searching for signs of life (“biosignatures”) and geologic dating.

To ensure they select the right samples, scientists must understand how rock samples formed and how they might have been altered over time. According to a new NASA study, Martian rocks may have been “shocked” by meteorite impacts during its early history (the Late Heavy Bombardment period). The role these shocks played in shaping Martian rocks could provide fresh insights into the planet’s geological history, which could prove invaluable in the search for evidence of past life on Mars.

How Will NASA and ESA Handle Mars Samples When They Get Them Back to Earth?

We’ve learned a lot about Mars in recent years. Multiple orbiters and hugely-successful rover missions have delivered a cascade of discoveries about our neighbouring planet. But to take the next step in unlocking Mars’ secrets, we need to get Martian samples back to Earth.
