This missing object has been found in space for 4 years

About four and a half years after the last signal, a French nano-satellite has miraculously returned to life. He could soon return to service to carry out his mission.

He was thought to be lost forever after his sudden disappearance from the radar on March 20, 2018, just over four years ago. But on June 22nd, PicSat, a French nano-satellite Designed and built by researchers and engineers from the Paris Observatory and the National Center for Scientific Research Miraculously brought back to lifeas announced by the Laboratory for Space Studies and Astrophysics Instruments (LESIA Astro) on Twitter.

“We thought it got lost, and promised to disintegrate in Earth’s atmosphere in silence. The IamPicSat nano-satellite designed and manufactured at LesiaAstro returned a signal after 4 and a half years of radio silence. It was launched on a PSLV rocket Jan. 10, 2018”Can we read in the publication published by the organization.

Nano-satellite reappears after 4 years of disappearance

And this is actually a small miracle, because the nano-satellite, consisting of three cubes of 10 cm each and no heavier than a cat (3.5 kg), took no help for sending this signal. Better: According to some, the machine will be very active and can show itself operational to carry out the task for which he was sent into space. “What great news”the reaction of the National Center for Space Studies (CNES) on the social network.

The task in question: Go and collect data to Learn more about the Beta Pictoris star system“a star in the southern hemisphere sky” as defined by CNRS, located 63.4 light-years from our world. “It is a very young star, only 23 million years old, and has fascinated researchers since the discovery of a large disk of dust, gas and rocky debris around it in the early 1980s.”says the organization.

Observing a giant gaseous exoplanet

More interesting task where at the heart of this file system A gas giant exoplanet, Beta Pictoris bAnd the “A mass seven times greater than that of Jupiter, which orbits its star 1.5 billion km away, like Saturn around the sun”.

By observing aberrations and differences in light as it passes in front of its star, nanosatellites can collect multiple data such as “Exact size of an exoplanet, extent and composition of its atmosphere, and chemical composition”. This is what is called in astronomy transit method.

But a problem remains: this transit, which lasts only a few hours in the case of Beta pectoris b, Reproduces…every 18 years. However, the last passage of an exoplanet in front of its star dates back to the summer of 2018. So PicSat may have to give up its long journey, but it’s not impossible for it to end up heading to another system.

Be that as it may, before resuming service, the satellite must first pass a diagnostic evaluation of its condition with the aim of determining whether it is still capable of executing such a challenge. A review already scheduled by LESIA Astro:
