600 pound spacecraft
The US Department of Defense, which is monitoring the satellite, is expecting the 660-pound spacecraft to re-enter the atmosphere on Wednesday around 9:30 p.m. EDT (7 a.m. IST), but the timing varies. It is possible While NASA expects most of the spacecraft to burn up as it travels through the atmosphere, some are expected to survive re-entry. “The risk of harm to anyone on Earth is low,” the agency said in a statement.
what was this mission
The spacecraft launched aboard an Orbital Sciences Corporation Pegasus XL rocket with a mission to image high-energy electrons, which carry a large portion of the energy released in solar flares. It achieved this with its only instrument, an imaging spectrometer, which recorded X-rays and gamma rays from the Sun. Prior to RHESSI, neither gamma-ray images nor high-energy X-ray images had been obtained for solar flares. Data from RHESSI provided important clues about solar flares and their associated coronal mass ejections.
what happens in this event
These events release energy equivalent to billions of megatons of TNT into the solar atmosphere within minutes and can have effects on Earth, including disruption of electrical systems. Understanding them has proved challenging. During its mission life, RHESSI recorded more than 100,000 X-ray events, allowing scientists to study energetic particles in solar flares. The imager helped the researchers determine the frequency, location and speed of the particles, which helped them understand where the particles were accelerating.
