A small Pandora satellite to open the secret box of the alien world

Despite decades of space exploration, we still do not know the fact that there is an alien civilization there. But at least now, we undoubtedly know that galaxies have enough planets to support them.

To date, more than 4,000 exoplanets have been found orbiting the distant Sun, according to NASA, and the number could increase as more and more observational hardware is put into combat. There is sex. Twenty such planets will be the focus of a mission called Pandora, which aims to better determine the composition of each atmosphere.

Pandora is one of three projects NASA It gave a green light as part of a low-cost astrophysics program called Pioneer. In fact, it’s a small satellite, weighing less than 180 kg (397 lbs), the size of a large kitchen refrigerator.

Pandora is placed in a sun-synchronous low earth orbit, so the stars of the solar system are always behind it. Observe both those planets and their stars for a long time with visible and infrared light toward the target planets.

Unlike other similar systems in use today, Pandora needs to be separated by observing the signals of stars and exoplanets at the same time. This eliminates the problems caused by changes in the light of the star in question.

“The science of exoplanets is moving from the era of planetary discovery to the era of atmospheric characterization.” In a statement, Elisa Quintana, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Pandora’s senior researcher, said.

“Pandora focuses on trying to understand how stellar activity affects exoplanet atmospheric measurements, thereby finding planets with an Earth-like atmosphere. It lays the foundation for the intended future exoplanet mission. “

Pandora is designed to work with the upcoming Pandora James webb Space telescope. It is operated by Lawrence Livermore National Laboratory (LLNL) in Livermore, California, and NASA’s Goddard Space Flight Center.

The launch dates for the mission and target planets have not yet been announced. A small Pandora satellite to open the secret box of the alien world
