The Edge of Space: Scientists Track Transition to Space

In summary, scientists at the University of Calgary have developed a new instrument that can accurately determine the boundary between Earth's atmosphere and space. This instrument has confirmed that space begins 118 km above Earth and can capture detailed information about the transition between the two. This research has been published in the Journal of Geophysical Research and has the potential to lead to further discoveries about the boundary between Earth and space.

Where does space begin? Scientists at the University of Calgary have created a new instrument that is able to track the transition between the relatively gentle winds of Earth's atmosphere and the more violent flows of charged particles in space – flows that can reach speeds well over 1000 km/hr. And they have accomplished this in unprecedented detail.

With that data, U of C scientists confirmed that space begins 118 km above Earth and the results were published this week in the Journal of Geophysical Research.


So, the X-15 never really make it to outer space.

"I find this research fascinating! It's amazing to think about the boundary between Earth's atmosphere and space and how this new instrument can track the transition between the two. The fact that it can capture such detailed information is truly impressive. I can't wait to see what other discoveries come from this technology."
 

Related to The Edge of Space: Scientists Track Transition to Space

1. What is considered the "edge of space"?

The edge of space is defined as the boundary between Earth's atmosphere and outer space. This boundary is typically considered to be at an altitude of about 62 miles (100 kilometers) above the Earth's surface.

2. How do scientists track the transition to space?

Scientists use a variety of methods to track the transition to space, including satellites, weather balloons, and high-altitude aircraft. These tools collect data on atmospheric conditions, temperature, and air pressure to determine the boundary between Earth's atmosphere and outer space.

3. Why is it important to study the edge of space?

Studying the edge of space can help scientists better understand our planet's atmosphere and how it interacts with outer space. This knowledge is crucial for predicting and understanding weather patterns, as well as for developing technologies for space exploration.

4. How has the edge of space changed over time?

The edge of space is not a static boundary and can shift depending on various factors such as solar activity and atmospheric conditions. Scientists have observed changes in the boundary over time and continue to monitor and study these changes.

5. What are some challenges scientists face when studying the edge of space?

One of the main challenges scientists face when studying the edge of space is the extreme environment, which can be difficult to access and measure accurately. Another challenge is the constantly changing boundary, which requires ongoing research and data collection to fully understand.
