NASA's SPHEREx space telescope launched into orbit by a SpaceX Falcon 9 rocket

Nasa Sphere The observatory is now in space For a mission of two years of creating a 3D card from all over the celestial sky. The telescope left the ground above a Falcon 9 rocket from a launch ramp in California, four years after NASA announced That a SpaceX flight will launch the mission, as well as the Punch microsatellites (NASA polarimeter to unify the corona and heliosphere microsatellites). Spherex separated from the SpaceX vehicle at 12 noon in the east on March 12 and will remain in low terrestrial orbit, where he will maintain a position compared to the sun which will remain the same throughout the year.

Every 98 minutes in orbit that the observatory will allow it to see a 360 -degree sky band in the optical and close infrared light. The telescope can capture more 360 ​​-degree bands when the earth moves around the sun, which allows it to map the whole celestial sky in the six months. Spherex was designed for image the whole sky every six months in two years, his goal was to create a 3D card of more than 450 million galaxies. The image telescope and will also collect information on more than 100 million stars in the Milky Way.

The Spherex card is necessarily colorful: it will separate the infrared light emitted by the stars and galaxies in 102 individual colors using a technique called spectroscopy. NASA compares to "The way a prism divides sunlight into a rainbow." The agency indicates that the observation of objects of different colors will reveal various properties about them, such as their composition. For galaxies, their colors could help scientists determine their distance from our planet. The data provided by Spherex will give scientists information about what happened just after Big Bang and could provide evidence of cosmic inflation, or rapid expansion of the early universe. Spherex will allow the protection coverage of its telescope in four days and will start its scientific operations in just over a month once its temperature has been cooled.

Meanwhile, the four punch satellites, which will also have a synchronous synchronous orbit, will map the crown of the sun by taking polarized white light images of the celestial object. It will collect data to help us better understand how the crown turns into a solar wind, which could cause precise predictions of spatial weather events affecting a spacecraft orbit around the earth.
