Exploring the Impact of Elon Musk's SpaceX Rocket Launches
Written on
Chapter 1: The Falcon 9 Launch
On July 19, Elon Musk successfully launched the Falcon 9 rocket, a sophisticated two-stage vehicle crafted by SpaceX. This rocket features a reusable first stage and an expendable second stage, powered by nine advanced Merlin engines, boasting a maximum payload capability of 22,800 kg to low Earth orbit. However, recent observations suggest that this robust rocket may have inadvertently created a hole in the ionosphere.
A space physicist from Boston University, Jeff Baumgardner, examined the launch footage and detected a faint red glow, which typically signifies the formation of an ionospheric hole.
Section 1.1: Understanding the Ionosphere
The ionosphere is a region at the fringe of space, composed of charged particles known as ions. These ions interact with solar plasma, resulting in the stunning auroras seen near the poles in both the northern and southern hemispheres. Jeff Baumgardner noted, “This is a well-studied phenomenon when rockets are burning their engines 200 to 300 km above Earth’s surface. When I reviewed the footage, it shows the second stage engine burning at 286 km near the F-region peak at that time of day. So, it is quite possible that an ionospheric ‘hole’ was made.”
Subsection 1.1.1: The Physics Behind the Phenomenon
Rocket engines emit a mix of water (H2O) and carbon dioxide (CO2) into the ionosphere, which can lead to a significant decrease—up to 70%—in local ionization levels. This reduction is a result of complex charge exchange reactions involving oxygen ions (O+) and the exhaust molecules released by the rockets. Consequently, photons are emitted at a specific wavelength of 6300 Ångströms, generating the red glow often seen in natural phenomena like auroras.
Section 1.2: Implications of Ionospheric Holes
The holes created by rocket launches tend to be temporary, lasting only for a brief period. However, during this time, they can disrupt GPS signals and interfere with various electronic devices. Although this isn't currently a major issue, the potential for more significant problems looms if these occurrences become frequent.
Chapter 2: Historical Context and Future Considerations
In 2017, another Falcon 9 launch carrying Taiwan’s FORMOSAT-5 payload resulted in the creation of substantial shock waves due to its vertical trajectory, leading to a hole in the ionosphere's plasma that was four times larger than California. While these holes tend to self-repair over time, the increasing frequency of rocket launches necessitates a more cautious approach from engineers and companies moving forward.
