Perseverance completed the samples for return to Earth

Ten sample tubes capturing the amazing diversity of Martian geology have been deposited on the Martian surface for future study on Earth.

Perseverance took this selfie looking down at one of the 10 samples she has stored in an area called “Three Forks.” This image was taken by the WATSON camera on the rover’s robotic arm on January 20, 2023 (Sol 684). Image credit: NASA/JPL-Caltech, MSSS.

Less than six weeks after the start of depositing the first samples on another planet, this task was completed. Confirmation that NASA’s Perseverance rover had successfully deposited the last tenth tube at the site was received Sunday, Jan. 29, at the Command and Control Center at JPL in Pasadena. This major milestone involved precise planning and navigation to ensure that the tubes would be safely picked up in the future by a joint mission between the US NASA and the European ESA – the “Mars Sample Return” mission. The goal of this mission is to bring samples from the surface of Mars to Earth.

During its mission, the rover collected rock samples that the mission team evaluated as significant. One sample from each pair of samples collected is now stored in a selected location in the Jezero crater on Mars. These samples will only serve as a backup set, as each sample was taken “in duplicate” and one of each sample is stored directly on board the Perseverance rover. These will serve as the primary set, which will be transferred by the rover directly to the lander that will land on Mars in this location as part of the aforementioned planned joint NASA-ESA mission and will then be delivered to Earth.


The Perseverance rover and its mission include the little flying robot Ingenuity, which arrived on Mars literally “on the belly” of Perseverance.

Ingenuity is essentially a technical demonstrator. It means that the goal of Ingenuity was to test the possibilities of flying in the conditions of Mars. The atmosphere of Mars is much thinner than the atmosphere of the Earth, and the air pressure at the surface is 100 to 150 times lower than it is on Earth, so it was questionable how a small helicopter would behave in these conditions. The first flight was of course a success and it was proven that our technology works. Several flights followed, all of which were successful, and so Ingenuity serves as our other eyes on Mars and sends us interesting images of this beautiful and silent planet.

Can you find Ingenuity in this photo? It is located in the center of the frame. Ingenuity’s distance in this image is exactly 295 meters (970 feet) from Perseverance. Image credit: NASA/JPL-Caltech.

Tianwen 1: first scientific results of the onboard magnetometer

The Mars Orbiter MAGnetometer (MOMAG) is a scientific instrument on board the first Chinese mission to Mars – Tianwen-1. From November 13, 2021, the Tianwen 1 orbiter began to routinely measure the effects of the solar wind on the magnetic field in places where it occurs around Mars.

The planet Mars does not have a bipolar magnetic field like Earth, only in some places around the planet, there is a certain form of the magnetic field. The results of the measurements confirmed the structure and strength of the magnetic field, exactly as they were previously measured by the American orbiter MAVEN (Mars Atmosphere and Volatile Evolution, NASA).

Curiosity continues to explore

The Curiosity rover of the MSL mission (NASA) continues to examine surface samples according to the established plan. Since the beginning of the year, she had several stops planned, and during one of them, the mission team came across another interesting “stone”. The shape of this specimen resembles a meteorite, several of which have already been identified on the surface of Mars.

So is it a meteorite or not? The image was taken with Curiosity’s left navigation camera, Sol 3724. Image credit: NASA/JPL-Caltech.

The exact determination of whether it is really a meteorite or not will be brought only by further examination of this “suspicious” stone. Of course, it can be a piece of rock that is just weathered into a form resembling a meteorite. Accurate information will help us learn the details of the surface of Mars in this location and contribute to the overall picture of the planet’s development.
