This picture shows the Lunar Equipment Support Assembly (LESA) being tested during a partial-gravity parabolic flight. In April, ESA, along with the French space agency CNES and the German Aerospace Center DLR, sponsored a parabolic flight campaign. The campaign consisted of three flights, each featuring 31 parabolas, allowing scientists to replicate the gravitational forces of both the Moon and Mars. During those 93 parabolas, the gravity experienced by the crew was reduced to one-sixth (to simulate lunar gravity) or one-third (to mimic Martian gravity) of Earth's gravity.
Under the watchful eye and guidance of ESA astronaut and spacewalk trainer Herve Stevenin, ESA astronaut Thomas Pesquet, who was one of the pilots of the spacecraft, couldn't resist a quick try during a break - the pilots rotate every few parabolas.
The heart of the LESA investigation lies in its various transport carrier prototypes on wheels to assist Artemis astronauts during moonwalks. The mobility of these carriers, designed to transport equipment and tools, was evaluated along a four-metre path inside the a ircraft.
The version of the carrier in the image is called LESA-NEST (Near-by Equipment Support Trolley), and it is designed for transporting tools and equipment.
LESA was previously tested in another unique environment: submerged during the NASA-NEEMO 23 mission in 2019. Led by ESA astronaut Samantha Cristoforetti, astronauts lived and worked underwater for nine days inside Aquarius, the world's only undersea habitat, and tested a set of geological sampling tools and the LESA support trolley to be used during future missions to the Moon.
After conquering water and air, hopes are set for a testing on the next great frontier, the Moon.
