NASA launches tiny satellites to investigate "bubbles" in the upper Earth's atmosphere



NASA will launch two identical miniature satellites next week to understand how the Earth's atmosphere clouds the radio signals we rely on for communication and navigation.

The pair will consist of a total of 24 satellites satellite launch aboard the SpaceX missile Falcon Heavy, which is flying into space for the third time. The launch date is scheduled for June 24 after some delays. The two identical spacecraft are Cubesats, miniature satellites that were originally used only in near-Earth orbits, but are now sometimes used for interplanetary missions at home. When orbiting near Earth, they provide scientists with important information about how radio signals can be disturbed as they pass through the upper atmosphere of the planet.

Earth's ionosphere, a layer in the upper atmosphere bombarded by solar and cosmic radiation and therefore full of charged particles contains "structured bubbles". These bubbles can distort radio signals that interfere with military and aviation communications and GPS signals, NASA said in a statement, particularly about the Equator.

If we learn more about these bubbles, we can avoid that According to NASA, they cause signal problems. However, scientists currently do not know when bubbles will form or how they will change over time. "It's difficult to inspect these bubbles from the ground," said Rick Doe, payload program manager for the E-TBEx mission, in the statement. "When you see bubbles begin to form, they move."
