New research suggests that greenhouse gas emissions can affect satellite launch in the future. As it produces, pollution causes the atmosphere to the upper environment, potentially increasing the risk of satellite collision in the orbit.
This is still another way that fossil fuel emissions are tangly affecting people depend on every day, especially telecommunications companies launch the megacantelation of satellites. Space, it turned out, is a limited tool – and climate change makes things more restrictive, because it has to be better managed, studying authors argue.
“We really have reached the end of that age of space, and I think we should stop saying it,” William Parker says, the main author of this StudyWhich was published today NatureAnd PhD candidate in Massachusetts Institute Technology F Technology. “People have no idea that space durability is actually an issue that directly affects them.”
“We really have reached the end of the era of ‘space is big’.
Greenhouse gas emissions keep the heat in the lower environment, which increases the global average temperature on the earth. The second side effect makes it low heat in the atmosphere of the earth, and the heat that disperses more easily in space. It results in cooling and contraction in the atmosphere above. Parker says that if you put it in the freezer you may think like a balloon shrink.
People eventually depend on a strong atmosphere to pull down dead satellites and other orbital debris, most of which are finally burned out of the atmosphere. But as the atmosphere becomes less ga ense, it reduces cramps on the debris of space, extends it to the orbit for a long time – and expands the lifetime that has to crash into other objects.
According to the study, the satellite carrying capacity can reduce the earth between 200 to 1000 km between 50 and 66 percent, according to the study. It will be 75 years from now on, a The worst situation Continuous fossil fuel development on earth and increasingly with the emission of greenhouse gas with a lifestyle. Luckily, that means that there is still some time to limit the risks that can rise in greenhouse gas emissions satellites. In one Medium view By the end of the century it is considered to be more likely, with moderate greenhouse gas emissions, the same IT will decrease between 24 and 33 percent of the capacity carrying capacity.
It will still be a significant change that will have to be prepared by satellite operators, especially because the orbit of the lower earth is becoming more congested. Humans are Launched about 20,650 satellites from 1957, of which 11,100 are still working. Those are numbers Drying With the advent of satellite internet services in the past decade. The Starlink of SpaceX alone has plans to send many 42,000 satellites In orbit.
There is a growing concern as the junk stands in space. SpaceX satellites had to do A maneuver to avoid 50,000 collisions In the first part of 2024 to avoid other spacecraft and debris. And as the greenhouse gas emissions increase, more obstacles may have to be maneuvered.
There is Previous research How greenhouse gas emissions cause shrinking and cooling in the atmosphere above. According to Petra Petrcha, researcher at the University of Charles University, the first attempt is to certify the effect of decreasing atmospheric density on the orbit orbit capacity of the lower Earth. Parker and its colleagues used atmospheric models how many satellites could safely orb into views of various greenhouse gas emissions. -It notes that there are other factors that can cause short-term inconsistencies in density, especially on how the atmosphere waves will react to the atmosphere of gravity due to the emission of greenhouse gas.
The Parker wants to ensure that we can avoid the tipping point where all the traffic of the lower earth triggers the cascading collections, allowing humans to lose access to certain parts of the space, as the road closes after the highway pilup. At this time, humans depend on satellites for everyday services – from GPS to weather forecasts.
“We all want to ensure that future pay generations are able to take advantage of the benefits of space,” says Parker. “I think the goal behind this paper was to engage people a little … space durability affects them. And within the satellite operator porter community, people know that this resource is limited and it is changing. “
