Vande Hei è entrato nei libri dei record martedì 15 marzo 2022: ha battuto il record per la maggior parte dei giorni consecutivi nello spazio da parte di un esploratore americano.

Vande Hei è arrivato alla stazione spaziale il 9 aprile 2021 e dovrebbe tornare a casa il 30 marzo 2022 dopo aver trascorso 355 giorni in orbita terrestre bassa. Questa durata batte il record precedente di[{” attribute=””>NASA astronaut Scott Kelly, by 15 days.

His then-crewmate Thomas Pesquet, who snapped the picture, said: “If you are reading this sitting down, maybe on a sofa or couch, consider that we will not sit down… until we are back on Earth! Of course, we don’t need to sit down up here, and I am not complaining at all, but sometimes that wonderful feeling of relaxation – that moment when you change from running around to letting yourself drop into a chair – that moment can be wonderful I am sure you all agree, and we do miss it sometimes! I think Mark did here too and made a makeshift reading table to enjoy a book – absolutely unnecessary in weightlessness but so nice to construct some semblances of normal life every now and again!”

I contributi dell’astronauta della NASA da record Mark Vande Hei a Human Research Studies

L’astronauta della NASA Mark Vande Hei è arrivato sulla Stazione Spaziale Internazionale il 9 aprile 2021 e dovrebbe tornare a casa il 30 marzo 2022 dopo aver trascorso 355 giorni in orbita terrestre bassa. Quella durata batte di 15 giorni il record precedente stabilito dall’astronauta in pensione della NASA Scott Kelly.

Vande Hei dovrebbe tornare su una navicella spaziale Soyuz insieme ai cosmonauti Pyotr Dubrov e Anton Shkaplerov.

Mentre completava il volo spaziale singolo più lungo di un astronauta della NASA, Vande Hei ha contribuito a dozzine di studi tra i centinaia condotti durante la sua missione, comprese sei indagini scientifiche supportate dal Programma di ricerca umana (HRP) della NASA.

“I nostri astronauti sono esploratori incredibili che stanno aiutando a far progredire la nostra conoscenza di come gli esseri umani possono vivere e lavorare nello spazio per lunghi periodi di tempo”, ha affermato l’amministratore della NASA Bill Nelson. “La missione da record di Mark e i contributi alla scienza aprono la strada a più persone per viaggiare nello spazio in missioni di lunga durata mentre l’agenzia spinge le frontiere dell’esplorazione lunare e terrestre[{” attribute=””>Mars. Thank you for your service, Mark, and congratulations!”

For one investigation, Vande Hei helped grow and evaluate vegetables harvested with the space station’s Vegetable Production System, or Veggie. The investigation seeks to develop a food production system that can help astronauts meet their dietary needs with fresh vegetables cultivated in space.

Vande Hei also provided biological samples for an investigation that collects a core set of measurements, called Spaceflight Standard Measures. The investigation seeks to characterize “normal” changes in the human body during spaceflight. For instance, wrist-worn sensors that measure activity levels and light exposure can help researchers better understand the sleep-wake cycle of astronauts. Blood and saliva samples collected by crew members throughout their mission can also help scientists assess changes in various hormones, proteins, and cells that reveal how the immune system changes in space.

In addition, he contributed to a separate investigation collecting biological samples from the crew aboard the space station and placing them in a storage bank. Researchers can draw upon the samples to study spaceflight-induced changes in human physiology.

Vande Hei also participated in the first formal investigation into how eating repetitive meals in spaceflight changes the appeal of certain foods over time. In space, menu fatigue can have serious consequences, including lost appetites, nutritional deficiencies, and loss of body mass. Results will help researchers improve the design of current and future space food systems.

He is also the first astronaut on an extended mission to help researchers investigate whether an enhanced spaceflight diet can allow humans to better adapt to space. Scientists seek answers to questions such as: Could a diet packed with foods rich in nutrients such as flavonoids, lycopene, and omega-3 fatty acids boost immunity and gut microbe function on long journeys into space?

After he lands, Vande Hei will provide additional feedback to researchers investigating potential injuries such as bruises incurred by astronauts from the force of landing. This feedback will help scientists better understand whether long-term human spaceflight makes crew members more susceptible to such injuries. Results will also help NASA design protective measures in future spacecraft.

Vande Hei’s contributions will expand NASA’s knowledge about how the human body adapts to long-term spaceflight as the agency plans for future missions to the Moon and Mars. Until then, taking time to relax and read will help him balance out the rigors of space travel.

NASA’s Human Research Program, or HRP, pursues the best methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and the International Space Station, HRP scrutinizes how spaceflight affects human bodies and behaviors. Such research drives HRP’s quest to innovate ways that keep astronauts healthy and mission-ready as space travel expands to the Moon, Mars, and beyond.
