Up to now, NASA's space observation missions such as Kepler have discovered thousands of exoplanets in the so-called livable zone. However, many potential candidates are likely to be hidden under the eyes of people, but these instruments are currently invisible. So for researchers, the problem they face is not just to create a powerful space telescope, but to change the way people identify exoplanets.
Engineers from the NASA Jet Propulsion Laboratory believe that if they want to become more creative, people not only need to increase their horizons in space in certain areas, but also need to be fuzzified in other areas. As part of the NASA Exoplane Exploration Program (ExEP), the research team is looking to see how stellar shadows may improve by effectively blocking the glare that might flood sensitive instruments.
According to the ExEP team, the two spacecraft will be deployed and coordinated. The second spacecraft will deploy a telescope that will project its gaze onto a planet outside the solar system, while at the same time the second spacecraft will fly before the first spacecraft, when it acts as a flowering giant. The role of the umbrella.
In this way, the second spacecraft can help the first spacecraft block the brighter stars, so the telescope may become more useful. But of course you need some highly accurate positioning to achieve this.
For a space telescope with a main mirror diameter of about 8 feet, it requires a sun visor about 85 feet in diameter, and the sun visor needs to be between 12 and 500 miles from the telescope.
Within this range, the sun visor needs to be consistent with the paired telescope, within a range of 3 feet. If this is not the case, light will bypass its edges and flood the darker exoplanets.
In this regard, NASA's ExEP team believes that such precise flight is possible.
Unfortunately, NASA has not yet officially established this sun visor plan. However, if funds are available, the tool may eventually be launched after the Wide Field Infrared Sky Telescope (WFIRST) and put into use in the late 1920s.
