FANTASTIC IMAGES OF A NEW ERA

As I was stumbling upon a fantastic picture shared by Stéphane Querry (follow his blog Survols), look at what the Californians could see up in the sky yesterday, on Friday, December 22, 2017:

Alors que je suis tombé sur une vue fantastique partagée par Stéphane Querry (suivez son blog Survols), regardez ce que les Californiens pouvaient voir dans le ciel. C’était hier, vendredi 22 décembre 2017:

The trails left by SpaceX Falcon 9 launch were so spectacular that the Californian witnesses believed it was a UFO. Beyond these impressive images, a new era has just begun as this lift off has sent 10 telecommunication satellites into space to build up the « orbital real estate » of the Iridium® satellite constellation. Aircraft, ships and land vehicles navigation will never be the same thanks to this network:

Les traînées laissées par le lancement de SpaceX Falcon 9 étaient si spectaculaires que les témoins californiens ont cru qu’il s’agissait d’un OVNI. Au-delà de ces images impressionnantes, c’est une nouvelle ère qui vient de commencer étant donné que ce lancement a envoyé 10 satellites de télécommunication dans l’espace pour construire le « parc orbital » de la constellation Iridium®. La navigation des aéronefs, des bateaux et des véhicules terrestre ne sera plus jamais la même grâce à ce réseau:

The argument that the moon is a dry, desolate place no longer holds water.

Secrets the moon has been holding, for perhaps billions of years, are now being revealed to the delight of scientists and space enthusiasts alike.

NASA today opened a new chapter in our understanding of the moon. Preliminary data from the Lunar CRater Observation and Sensing Satellite, or LCROSS, indicates that the mission successfully uncovered water during the Oct. 9, 2009 impacts into the permanently shadowed region of Cabeus cater near the moon’s south pole.

The impact created by the LCROSS Centaur upper stage rocket created a two-part plume of material from the bottom of the crater. The first part was a high angle plume of vapor and fine dust and the second a lower angle ejecta curtain of heavier material. This material has not seen sunlight in billions of years.
