Astro Chat with Marco Sieber | ESA Explores podcast

Marco Sieber is one of ESA’s five astronaut candidates currently undergoing basic astronaut training at the European Astronaut Centre (EAC) in Cologne. Join us as we speak to Marco about his first months of training and living in Germany, his background as a medical doctor, his favourite training lessons, and what he is excited about for the future of space exploration.
This is the third episode of our ESA Explores podcast series introducing the ESA astronaut class of 2022. It was recorded in November 2023.

An augmented reality assessment designed to test astronaut adjustment to gravity changes

When shifting from the microgravity of a spacecraft to the gravity-rich environment of the moon or Mars, astronauts experience deficits in perceptual and motor functions. The vestibular system in the inner ear, which detects the position and movement of the head, must adjust to reinterpret new gravity cues.
A University of Michigan-led team, including researchers from the University of Colorado Boulder's Bioastronautics Lab and NASA's Neuroscience Lab at Johnson Space Center, developed a multidirectional tapping task administered in augmented reality (AR) to detect sensorimotor impairments similar to those observed in astronauts after spaceflight.
The results, published in Aerospace Medicine and Human Performance, could support mission operations decisions by establishing when astronauts are able to perform tasks that require full coordination, like piloting vehicles or operating other complex systems.
Field tests to assess sensorimotor impairment have previously been conducted upon the return of International Space Station crew members to Earth.
When an object like 'Oumuamua comes around again, we could be ready with an interstellar object explorer

On October 19th, 2017, astronomers with the Pann-STARRS survey observed an interstellar object passing through our system—1I/2017 U1 'Oumuamua. This was the first time an ISO was detected, confirming that such objects pass through the solar system regularly, as astronomers predicted decades prior. Just two years later, a second object was detected, the interstellar comet 2I/Borisov. Given 'Oumuamua's unusual nature (still a source of controversy) and the information ISOs could reveal about distant star systems, astronomers are keen to get a closer look at future visitors.
For instance, multiple proposals have been made for interceptor spacecraft that could catch up with future ISOs, study them, and even conduct a sample return (like the ESA's Comet Interceptor).

First US moon lander in half a century stops working a week after tipping over at touchdown

The first U.S. spacecraft to land on the moon since the Apollo astronauts fell silent Thursday, a week after breaking a leg at touchdown and tipping over near the lunar south pole.
Intuitive Machines' lander, Odysseus, lasted longer than the company anticipated after it ended up on its side with hobbled solar power and communication.

Space Team Europe: focus on Ariane 6

Meet the people working on the testing of Ariane 6. Europe’s next rocket, Ariane 6, has passed all its qualification tests in preparation for its first flight, and now the full-scale test model will be removed from the launch pad to make way for the real rocket that will ascend to space.
To make way for launch, teams from ArianeGroup, France’s space agency CNES and ESA have started to remove the Ariane 6 test model by disconnecting the cables and fuel lines that pass through the launch tower.

Top 5: Space for your health

Space has led to technological innovations with wide-ranging applications in healthcare. Beyond consumer gadgets, such as wireless headsets and scratch-resistant lenses, space exploration is a catalyst for understanding the human body and advancing scientific results that benefit people worldwide. Here are Europe’s top 5 stories in space for your health.
Gravity affects everything we do and everything that happens inside and around us. On Earth’s surface, everything is subject to an average gravitational acceleration of 9.81 m/s2, or what we call 1 g. This acceleration keeps us grounded but it also influences all reactions and phenomena around us, from falling apples
