NASA's SunRISE or Sun Radio Interferometer Space Experiment has been an ambitious that would plan to launch the biggest radio telescope ever to detect and track unsafe explosive space weather events. It has been mentioned by the US space agency that the production of the first six satellites has been completed at the Utah State University Space Dynamics Laboratory (SDL). Well, it has been noticed that the SDL had contracted to build, test, and commission all six satellites for the mission.

Anticipated for a launch in 2024, NASA's SunRISE would be a radio telescope in an orbit that would enable scientists to grasp explosive area weather events. It would use the combined power of six toaster-size satellites in order to observe the Sun in a way that so far has been 'impossible' from Earth's surface.

Jim Lux, the SunRISE project manager at NASA's Jet Propulsion Laboratory (JPL) in South California has mentioned that “It's very exciting to see the space vehicles to come together.”

Each small satellite or SmallSat was used in the SunRISE project that would perform as an individual to discover bursts of radio waves from the Sun's superheated atmosphere, which could be called as the corona. Therefore the satellites which were equipped with four telescoping antenna booms that would extend about ten feet (2.5 meters) to create an “X,' would orbit Earth at about 22,000 miles (36,000 kilometres) away, whereas moving along to trace out a virtual radio telescope.

Well, the signals, received from the six SmallSats via NASA's Deep Space Network, would be used by the scientists to make a large-aperture radio telescope as wide as the distance between the SmallSats that were farthest apart about 6 miles (10 kilometres), using the technique of interferometry. 

Unlike several ground-based radio telescopes that would also use interferometry to mix the observing power of many individual antennas, SunRISE would be able to see the long wavelengths that were blocked by a portion of the Earth's higher atmosphere which has been known as the ionosphere.

This means it would pinpoint where the solar radio bursts, or sudden event-type emissions of radio waves, erupt higher up in the Sun's corona. The data would be used by the SunRISE team to make elaborated maps of their positions in 3D.

Justin Kasper, the SunRISE principal investigator at the University of Michigan in Ann Arbor has mentioned that 'these high-energy solar particles would jeopardise the unprotected astronauts and technology. By tracking the radio bursts related to these events, we would be better prepared and informed.”

The observation from SunRISE was going to be used by NASA in conjunction with the data from different space missions and ground-based observatories.
