Nasa : une sonde retrouvée dans l’espace - #Cmr #Cameroun #Team237 #Team216 #Kebetu #Team241 #Team229 #Team221 #Team261 #Team224 #Team212

Perdu dans l’espace depuis près de deux ans et hors de portée des radars de la NASA, le satellite STEREO-B a finalement rétabli les liaisons avec l’agence spatiale, qui a ainsi pu le retrouvé. 

            Perdu dans l’immensité intersidéral depuis deux ans et sans aucun moyen d’entrer en contact avec la Terre,           c’est le périple qu’a connu STEREO-B, un satellite de la Nasa mis en orbite…

Spacecraft in solar orbit regains contact with Earth

This image shows our sun’s far side. It was obtained by the STEREO probes on Feb. 2, 2011 at 23:56 UT. Image courtesy NASA.

A probe launched by NASA in 2006 has resumed communication with the agency after nearly 23 months of silence.

The STEREO-B spacecraft, which orbits the sun, lost contact with Earth on Oct. 1, 2014.

The Deep Space Network reestablished the link with STEREO-B at 6:21 pm EDT on…

STEREO-A Spacecraft Returns Data From the Far Side of the Sun

This image of the sun was taken on July 15, 2015, with the Extreme Ultraviolet Imager onboard NASA's Solar TErrestrial RElations Observatory Ahead (STEREO-A) spacecraft, which collects images in several wavelengths of light that are invisible to the human eye. 

This image shows the sun in wavelengths of 171 angstroms, which are typically colorized in blue. STEREO-A has been on the far side of the sun since March 24, where it had to operate in safe mode, collecting and saving data from its radio instrument. The first images in over three months were received from STEREO-A on July 11.
