Russian cosmonaut Oleg Kononenko continues to cement a spot within the annals of area historical past together with his historic mission on board the Worldwide Area Station. On Wednesday, he turned the primary individual to achieve 1,000 cumulative days in area.
The milestone comes amid his fifth flight to area and through his third stint because the commander of the ISS. Again in February, Kononenko broke the cumulative in-space file of 878 days, which was beforehand held by former cosmonaut Gennady Padalka.
His most up-to-date journey to the orbiting laboratory started with a launch aboard the Soyuz MS-24 spacecraft on Sept. 15, 2023, alongside cosmonaut Nikolai Chub and NASA astronaut Loral O’Hara. He’s scheduled to return with Chub and NASA astronaut Tracy Dyson in September 2024.
Spaceflight Now spoke with Emmanuel Urquieta, the previous chief medical officer of the NASA-funded Translational Analysis Institute for Area Well being (TRISH), which is led by Baylor School of Medication. He was lately tapped by the College of Central Florida (UCF) to function the vice chair for aerospace drugs in its Division of Inside Medication.
“It takes a particular type of individual to have the ability to obtain such a file,” Urquieta stated. “It’s a very long time, however I feel that it’s a kind of knowledge factors that I hope that we’ll begin getting extra of these sooner or later.”
Urquieta participated in analysis regarding plenty of astronauts who’ve traveled to low Earth orbit for various lengths of time, together with the primary all-civilian mission, known as Inspiration4, in 2021. He pointed to 5 major areas of analysis that he and his colleagues hone in on in relation to higher understanding lengthy period spaceflight:
- Communication throughout a big distance from Earth
- Radiation publicity
- Isolation and confinement
- Extremely gravity fields (i.e. being in a zero g atmosphere)
- Dwelling in a hostile and closed atmosphere
He stated Kononenko offers a novel alternative to additional our understanding of the impacts of long-duration spaceflight on the human physique.
“Though folks may ask, ‘Okay, effectively, it’s not a single mission, proper? There have been a number of missions that made that 1,000 days? Effectively, nonetheless in that case, this can be very related to us to know how a number of exposures to spaceflight have had impacts, in what extent, within the totally different physiological ranges,” Urquieta stated.
“I’m positive that there might be loads of analysis developing sooner or later when he comes again to Earth and I’m positive that there might be a really lengthy comply with up with him, you understand, days, months and years after, to strive actually to know these very distinctive knowledge factors.”
With an eye fixed on long-duration missions on the floor of the Moon within the 2030s and expeditions to Mars additional down the street, Urquieta stated it’s essential to study as a lot as potential about issues like radiation publicity, eye well being, bone loss and area movement illness.
He stated a lot of that studying comes from the six-month crew rotation missions onboard the ISS.
“While you extrapolate the information that we’ve got from six-month missions to 900 days, there’s nonetheless an enormous hole of information that we have to fulfill, that we have to get in order that we will safely say that, okay, we’ve got sufficient knowledge that we will confidently say that we’re in a position to ship somebody to Mars and guarantee that that individual goes to come back again as wholesome as she or he left Earth,” Urquieta stated.
Unequalled file
After Kononenko, the subsequent most skilled flier, who can be at present eligible for future missions, is former NASA astronaut Peggy Whitson. She at present works as a personal astronaut at Houston-based Axiom Area and notched greater than 675 days on orbit, together with her first mission as a personal commander of Ax-2 in 2023.
The lively obligation NASA astronaut who comes closest to Kononenko’s file is Mark Vande Hei who spent a complete of greater than 523 days in orbit throughout two separate missions.
At the moment, NASA isn’t planning missions to the ISS longer than about six months. The company makes use of the SpaceX Crew Dragon to ferry its astronauts to area for these long-duration missions earlier than they hand over on-orbit duties to the next crew. The company plans to make use of Boeing’s Starliner spacecraft to do the identical, as soon as it’s licensed within the aftermath of the Crew Flight Check.
The newest occasion of a NASA astronaut spending a steady yr in area was Frank Rubio’s first journey to orbit. His 370 days on orbit have been unplanned on account of a difficulty with the Soyuz car that was deemed unsafe to return him and his Russian colleagues to Earth.
Urquieta stated he wish to see extra year-long missions deliberate as time goes on and NASA will get nearer to sending people to Mars. However he stated the six-month missions are nonetheless priceless because the Artemis program prepares to ship people again to the Moon for more and more longer stays.
“These late Artemis missions are going to be longer in period and people ones are going to be a testbed for Mars. So, I count on that these late Artemis missions might be growing in period, possibly to the extent of longer than a yr,” Urquieta stated. “However for the Moon, I feel that six-month missions on the ISS nonetheless offers priceless and dependable info to maintain informing the choices for Moon touchdown or lunar exploration-type of missions.”
And even when Kononenko’s towering file stands for years to come back, Urquieta stated the extra we study in regards to the human physique in area, the higher we will deal with older people right here on Earth and several types of illnesses. Not solely that, however he stated working extra with drugs in area can supply higher options in relation to healthcare for these in properties and communities which can be far faraway from hospitals or clinics.
“Even nonetheless right here within the U.S., there are many populations which can be 100 miles away from the closest hospital and from the closest pharmacy,” Urquieta stated. “Think about that functionality of not having to see a doctor and you’ll nonetheless be capable to have some preliminary medical choice assist and provoke the therapy.”
“I feel that might be extraordinarily, extraordinarily related to underserved and remoted populations, not solely within the U.S., however actually on the planet.”
