JAKARTA – A total solar eclipse will cross the United States on April 8. When this natural phenomenon occurs, three experiments supported by NASA will study the ionosphere.
The ionosphere is a layer of the atmosphere at an altitude of 60 to 600 kilometers. This part of the atmosphere is formed because sunlight separates negatively charged electrons from atoms and creates positively charged ions.
Therefore, the ionosphere really needs the Sun. During the total solar eclipse phenomenon, scientists will observe its impact on the ionosphere layer. These observations will be made with three NASA-funded technologies.
The first technology to be used is the Super Dual Auroral Radar Network (SuperDARN). Based on NASA’s explanation, this technology will reflect radio waves from the ionosphere and analyze ionospheric density, temperature and location data.
Bharat Kunduri, one of the scientists who will observe SuperDARN data, said that the technology, “Will operate in a special mode designed to monitor ionospheric changes at finer spatiotemporal scales.”
Next, the ionosphere will be observed using radio technology in the Ham Radio Science Citizen Investigation (HamSCI) project. This project, funded by NASA, will involve amateur radio operators from various countries around the world.
All radio operators will send and receive signals to each other before, during and after the total solar eclipse occurs. This was done to determine the effect of the loss of sunlight on the radio signals they use.
The latest project funded by NASA is RadioJOVE. When a total solar eclipse occurs, scientists on the project will use radio antenna equipment to record radio bursts emitted by the Sun.
