A mini solar telescope riding at the International Space Station first caught images, which reveals the subtle and never seen changes in the outer environment of the Sun. It is known as a coronal diagnostic experiment (codax) and is designed to deeply understand the outer layer of the solar corona, the sun. This mini telescope acts like a corongraph, which blocks the sun’s disc to mimic the total solar eclipse. Codex was distributed on 5 November 2024 via SpaceX Dragon. It was placed on the ISS on 9 November 2025 using the Canaderm 2 robotic arm.
Revolution in solar observation
As Report By NASA, the unique design of Codex includes a secret disc, which is the size of a tennis ball organized by three weapons made of metal. This allows to block acute sunlight when imaging the unconscious corona. The first images were revealed On June 10, 2025, at the time of meeting of American Astronomical Society in Alaska. These included coronal streamers in the outer corona in several days and footage of the temperature. It provides a new approach Solar mobility,
It was never before measuring solar air
Codex is unlike the previous corongraph as it is the first to measure both solar wind speed and temperature. There is a continuous flow of superhot particles from the Sun. With the help of four narrow filters, in which two are used to determine the temperature and for two speeds, astronomers compared these properties to decode the glow, which helps to solve the mystery solar wind 1.8 million degrees reaches Fahrenheit.
Set up solar weather challenge
To know the solar wind, it is important to predict geomous storms triggered by coronal holes. Soon, storms were seen on 13 June, 2025 and 25 June 2025, causing other incidents and caused the other incidents. After refining solar air analysis, Codex can help reduce such disturbances and predict.
Launch at one time between solar peaks
Nasal Codex began operating in a suitable moment, such as the current solar comes to its end. As the Sun’s magnetic field turns during the solar battle region, Codex is ready to catch vital data that can change our understanding of the weather in space.
