The primary time German astronaut Alexander Gerst took off into area, he was overwhelmed. He’d seen satellite tv for pc photographs of Earth earlier than, however they had been nothing compared with the true factor.
“I [saw] the Earth with my very own eyes for the very first time and impulsively, this enormous, gigantic planet that I assumed was infinite, possibly with infinite assets or issues like that, appeared dauntingly small within the mild of the blackness of infinity. And that brought on me to see Earth otherwise.”
Gerst was a part of the Worldwide Area Station (ISS) Expedition 40 and 41 from Could to November 2014. He returned to area once more as a part of Expedition 56 and 57 in June 2018.

“It was revealing [for me] to fly to area for the primary time,” he mentioned. “As a geophysicist, we all know precisely the diameter of the Earth, the thickness of the environment. I assumed I knew all of it.”
Gerst, who spoke throughout final week’s 14th European Area Convention, mentioned area exploration can provide an answer to the local weather disaster by taking a step again and looking out on the “downside from the surface.”
“We astronauts have to move that view, that change in perspective [back] to Earth.”
Area finances spent on new applied sciences
Whereas area exploration calls for a substantial amount of cash from the EU finances, Gerst argues that it’s price it.
The advantages of applied sciences developed to assist area exploration aren’t merely restricted to sustaining human life in area, he mentioned.
Area expertise helps lead researchers to “develop applied sciences that we are able to use on Earth, issues that we have to save the planet,” Gerst mentioned.
Gerst mentioned they performed experiments on the area station that investigated how plant roots know which course to develop. This query is being closely researched with the intention to develop crops that may develop their roots extra rapidly to search out water deep in dry soil.
“That’s one thing that can are available in very useful if local weather change actually modifications a number of areas that previously had been inexperienced and now they’re dry,” he mentioned.
European Area Company (ESA) Director Common Josef Aschbacher famous that greater than half of the local weather parameters – similar to sea floor temperature, glacier melting, the melting of the polar ice caps and sea stage rise – are measured in area.
“With out satellites, we wouldn’t know the extent of local weather change,” Aschbacher mentioned, including that with out this info, it might be tough to make and implement choices associated to the local weather disaster.
‘We’re eyewitnesses of all this’
Throughout a digital interview with European Fee President Ursula von der Leyen from area final week, German astronaut and supplies scientist Matthias Maurer, who’s at the moment on a six-month SpaceX science mission, famous the numerous local weather change-related particulars observable from area.
Flying on the top of round 400 kilometers above the planet and circling Earth 16 instances a day, Maurer mentioned they’ll see slashed and burned forests, drought and lakes that was on the maps.
“We are able to additionally see that human mining places a number of scars into the floor of our planet,” he mentioned.
Maurer mentioned they’re additionally in a position to observe pure occasions taking place in actual time, just like the latest flooding in Brazil or the eruption of the underwater volcano in Tonga.
He added that the Copernicus Earth remark fleet offers knowledge that’s vital for politicians to behave upon.
Copernicus is the European Union’s Earth remark program. It affords info providers that draw from satellite tv for pc and non-space knowledge.
Maurer launched in November final 12 months on the SpaceX Crew Dragon Endurance spacecraft for a mission to advance scientific information and exhibit new applied sciences for future human and robotic exploration missions.
Plenty of area junk
A problem ceaselessly introduced up with area exploration is the particles it leaves floating round in area.
There are fears that with extra personal corporations vying to go to the moon, similar to billionaire Elon Musk’s SpaceX, extra junk will fill the environment.
Based on the ESA’s January 2022 replace on area junk, there are some 30,600 particles objects recurrently tracked by Area Surveillance Networks.
Maurer mentioned his area station skilled an area particles collision warning simply two weeks in the past. The station’s planning groups on the bottom needed to calculate if the particles had the potential to hit them.
“That exhibits us that there’s a lot of particles right here in area, and it is an important subject, not just for the ISS as a result of it places us in danger, but in addition due to the older satellites that we’ve got.”
Maurer famous there must be motion taken to keep away from future area particles. The ESA has declared that by 2030, they wish to have a internet contribution to area particles. Maurer mentioned this is able to not solely imply they should take motion to take away huge components from area, but in addition to cut back the introduction of recent area particles.
Each Maurer and Gerst are optimistic that the findings from area exploration might assist politicians and scientists discover options to the local weather disaster, utilizing the well-known phrases “there isn’t any Planet B.”
