Nasa : une sonde retrouvée dans l’espace

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

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.

NASA's STEREO-A (Solar TErrestrial Relations Observatory Ahead) space probe has resumed contact with the Earth a few days ago after more than three months and on July 15 sent new photographs of the other side of the Sun from the Earth. Its EUVI (Extreme UltraViolet Imager) instrument was used to take photographs at a wavelength of 171 angstroms, invisible the human eye, then colorized in blue to allow us to appreciate them.

La sonda spaziale STEREO-A (Solar TErrestrial RElations Observatory Ahead) della NASA ha ripreso i contatti con la Terra alcuni giorni fa dopo oltre tre mesi e il 15 luglio ha inviato nuove fotografie del lato del Sole opposto al nostro pianeta. Lo strumento EUVI (Extreme UltraViolet Imager) è stato usato per scattare fotografie alla lunghezza d'onda di 171 angstrom, invisibile all'occhio umano, successivamente colorata in blu per permetterci di apprezzarle.

Comet Jacques put on quite a show from the STEREO-A spacecraft, which is currently on the other side of the Sun along Earth's orbit. The comet was only about 0.32 AU (48 million km, 30 million miles) from STEREO-A, giving the spacecraft a dramatic view of the comet's tail as it flapped in the solar wind.
