Detect, fetch and collect. A seemingly easy task is being tested to find the best strategy to collect samples on the martian surface, some 290 000 million km away from home.
Testing technologies for Mars exploration is part of the daily job of Laura Bielenberg, an ESA graduate trainee for the Mars Sample Return campaign.
The test takes place at the rock-strewn recreation of the Red Planet at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. The nickname of this test site is the ‘Mars Yard’ and is part of the Planetary Robotics Laboratory.
The tube is a replica of the sample caches that NASA’s Perseverance rover is leaving on Mars hermetically sealed with precious martian samples inside. They are called RSTA, an acronym of Returnable Sample Tube Assembly, and to most people on Earth they look like lightsabers.
Laura is investigating sample tube collection strategies, from autonomous detection to pose estimation of sample tubes on Mars, with a testbed called the RABBIT (RAS Bread Boarding In-house Testbed).
The Sample Transfer Arm will need to load the tubes from the martian surface for delivery towards Earth. ESA’s robotic arm will collect them from the Perseverance rover, and possibly others dropped by sample recovery helicopters as a backup.
Besides cameras and sensors, the team relies on neural networks to detect the tubes and estimate their pose. Inspired by the way the human brain works, neural networks mimic the way biological neurons signal to one another.

The mission to return martian samples back to Earth will see a European 2.5 metre-long robotic arm pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery.
The sophisticated robot, known as the Sample Transfer Arm or STA, will play a crucial role in the success of the Mars Sample Return campaign. The joint endeavour between @NASA and ESA aims to bring back martian samples to the best labs in our planet by 2033.
The robotic arm will land on Mars to retrieve the sample tubes NASA’s Perseverance rover is currently collecting from the surface. Able to “see”, “feel” and take autonomous decisions, the Sample Transfer Arm will identify, pick up and transfer the tubes into the first rocket fired off another planet – the Mars Launch System.
Only after the robot closes the container’s lid, the martian samples will be launched for rendezvous with ESA’s Earth Return Orbiter (ERO) and bring the material back to Earth.
The Sample Transfer Arm is conceived to be autonomous, highly reliable and robust.
Its architecture mimics a human arm with a shoulder, elbow and wrist, and has its own built-in brain and eyes. The robot can perform a large range of movements with seven degrees of freedom.

NASA’s Mars 2020 Perseverance mission captured thrilling footage of its rover landing in Mars’ Jezero Crater on Feb. 18, 2021. The real footage in this video was captured by several cameras that are part of the rover’s entry, descent, and landing suite. The views include a camera looking down from the spacecraft’s descent stage (a kind of rocket-powered jet pack that helps fly the rover to its landing site), a camera on the rover looking up at the descent stage, a camera on the top of the aeroshell (a capsule protecting the rover) looking up at that parachute, and a camera on the bottom of the rover looking down at the Martian surface.
The audio embedded in the video comes from the mission control call-outs during entry, descent, and landing.

Where do we come from? Where are we going? Why are things the way they are? Space science and exploration are entering an ambitious new era, spanning the hunt for extraterrestrial planets and detecting the fundamental nature of our Universe to roving on Mars and returning to the Moon. However, we’re not simply acquiring new knowledge – we’re helping bring the benefits of these discoveries to European industry, through commercialisation in Earth orbit, integration with new space actors and cooperation on a global scale.

A European drill and sample analysis package will search for water ice and other chemicals under the lunar surface onboard the Russian-led Luna-27 mission to the South Polar region of the Moon.
Operating at temperatures of less than –100 °C and drilling over one metre down, Prospect first needs to penetrate the lunar surface. This video features a series of drilling tests carried out at the Leonardo facilities in Italy in 2019.
Prospect includes a miniature laboratory called ProSPA which will analyse the soil samples retrieved by the drill. Precise measurements will help unearth the secrets of the Moon’s history and indicate whether future explorers could use lunar resources on their missions to help set up a lunar base.
The lunar south polar region is of great interest to lunar researchers and explorers because the low angle of the Sun over the horizon leads to areas of partial or even complete shadow. These shadowed areas and permanently dark crater floors, where sunlight never reaches, are believed to hide water ice and other frozen substances that could be analysed to better understand the natural processes that formed them, and used to produce resources such as oxygen and propellant in the future.

Overview of the Heracles mission. We are leading an alliance of international space agencies to prepare a robotic mission to the Moon to retrieve samples and return them to Earth.
The video shows a launch on an Ariane 6 rocket, separation from the rocket boosters over Earth and a transfer to the Moon.
The Heracles lander will target a previously unexplored region near the lunar South Pole as an interesting area for researchers. A lander with a rover inside and ascent module on top will land there.
Monitored and controlled from the lunar Gateway, the rover will scout the terrain in preparation for the future arrival of astronauts, and collect samples.
The ascent module will take off from the surface and fly to the Gateway with the samples taken by the rover.
When the ascent module carrying the sample container arrives, the Gateway’s robotic arm will capture it and extract the sample container. The sample container will be received by the astronauts via a science airlock and pack it in NASA’s Orion spacecraft that is powered by the European Service Module.
Orion will fly to Earth with astronauts and land with the Heracles lunar samples for analysis in the best laboratories on Earth.
Other goals of the mission include testing new hardware, demonstrating technology and gaining experience in operations while strengthening international partnerships in exploration. Its development will provide an Ariane 64-based lunar cargo lander available for commercialisation by European and partners’ industry.
Heracles is an international programme to use the Gateway to the fullest and deliver samples to scientists on Earth using new technology that is more capable and lighter than previous missions.

Over the last two decades, space agencies have created more comfortable conditions on the International Space Station, but we need to explore the concept of ‘living in space’ much further if humans are to ever live and work on another world, such as the Moon or Mars.
ESA’s Discovery and Preparation Programme works to prepare ESA for the future of space exploration. As part of this programme, ESA has worked with academic and industrial partners on a huge number of studies that lay the groundwork for living in space.
The technology that exists today could easily take us to the Moon and beyond, but it is studies like those carried out under the Discovery and Preparation Programme that will make a trip resourceful, sustainable and productive.

Spacecraft in orbit and on Mars’s surface have made many exciting discoveries, transforming our understanding of the planet and unveiling clues to the formation of our Solar System, as well as helping us understand our home planet. The next step is to bring samples to Earth for detailed analysis in sophisticated laboratories where results can be verified independently and samples can be reanalysed as laboratory techniques continue to improve.
Bringing Mars to Earth is no simple undertaking—it would require at least three missions from Earth and one never-been-done-before rocket launch from Mars.
A first mission, NASA’s 2020 Mars Rover, is set to collect surface samples in pen-sized canisters as it explores the Red Planet. Up to 31 canisters will be filled and readied for a later pickup – geocaching gone interplanetary.
In the same period, ESA’s ExoMars rover, which is also set to land on Mars in 2021, will be drilling up to two meters below the surface to search for evidence of life.
A second mission with a small fetch rover would land nearby and retrieve the samples in a Martian search-and-rescue operation. This rover would bring the samples back to its lander and place them in a Mars Ascent Vehicle – a small rocket to launch the football-sized container into Mars orbit.
A third launch from Earth would provide a spacecraft sent to orbit Mars and rendezvous with the sample containers. Once the samples are safely collected and loaded into an Earth entry vehicle, the spacecraft would return to Earth, release the vehicle to land in the United States, where the samples will be retrieved and placed in quarantine for detailed analysis by a team of international scientists.
