It’s difficult to provide an exact distance of the Earth to the outer space since we can only observe a small volume within our range. This is one question that has attracted different opinions around the world with some maintaining that there’s nothing like an end to space. Reports show that the universe which is more than 13 billion years old has never received any light from a galaxy separated by a similar margin. And this raises a question as whether such galaxy exists in the first place. This comes as a new study that was published by Jonathan McDowel on the Internet more than two years ago indicates that 62 miles might not be the correct distance between the two. If his calculation is something to go by, the cosmic boundary that separates the Earth’s airspace and outer space has provided more realistic estimates than before.
An example of a cosmic boundary that’s widely accepted by all researchers is the Karman Line. Today, the altitude of Karman Line altitude is estimated to be close to 100?km of radius. In his article, Jonathan McDowel has raised concerns about the accuracy of data that’s commonly used. According to him, lots of findings are based on years of misinterpreted facts that don’t add up. Unlike previous researchers, McDowell knew what kind of information he needed to make his findings. Additionally, he mastered an art of collecting evidence that answered questions that were posed.
In answering the question as to where Earth space starts, McDowell made his findings by comparing different data collected from more than 43000 satellites that used orbital space. A good portion of information was provided by North American Aerospace Defense Command that monitors aerospace in both the US and Canada. Data shows that each satellite makes at least two rotations before entering Earth’s atmosphere. Satellites are expected to go around the Earth at altitudes that are below 62 miles. This was supported by the data collected from the Soviet Elektron-4 satellite that went around the Earth 10 times. The satellite recorded about 52 miles before turning into flames.
It does not matter how you’ll look at his new findings but a 62-mile mark that most scientists apply is far much higher. While determining an exact point that most satellites detach from their orbits before returning to the atmosphere, McDowell discovered that it occurs between 41 and 55 miles. It’s important to realize that the satellite will not detach from its orbit when the distance is below his 50 miles. It explains why McDowell picked 50th mark as a point of detachment. You need to note that this distance is supported by the available social and atmospheric factors. For example, a US Air Force pilot was rewarded after he succeeded in flying the plane above a 50-mile mark. This mark is considered to be the highest point that separates the Earth from space.
Subsequently, Mesopause layer of the atmosphere that’s said to be the coldest in the Earth’s atmosphere is estimated to stretch from 52 to 62 marks. It’s the highest point of the Earth’s space that has seen its chemical composition to change. For many, Mesopause is more in space than in the Earth’s atmosphere. Previous results have shown that lots of heavenly bodies such as meteors start to disintegrate between ranges of 70 and 100?km. What it means is that the distance between Earth and outer space could be much lower than what’s commonly accepted. It’s good to state that this isn’t going any physical interactions that happen in space. On the negative side, this might raise more issues that are related to political and boundaries.
Traditionally, airspace that’s above a certain country is always part of that country. Things become different when you move to outer space because it’s no man’s land. Since it’s common knowledge that 100 km is what separates the Earth and outer space, it comes with some challenges. As it stands, it will be an act military aggression to fly satellite at below 100 km without permission from a respective country. It is from this that the US government has rejected all proposals that could have seen the universal space boundaries set up. It’s clear that McDowell’s proposal of a 50-mile mark will never see the light anytime soon.
