Nouvelles découvertes lunaires

Grâce à un nouveau radar à haute résolution dans le désert de Mojave, la Nasa a mis en évidence, au pôle sud de la Lune, une région avec des pics aussi hauts que le Mont McKinley en Alaska (6.200 m) et des cratères quatre fois plus profonds que le Grand Canyon. Cette région pourrait être un objectif pour les futures expéditions lunaires.

Est-ce que les pics sont perpétuellement ensoleillés comme ceux découverts au pôle Nord ???

Incroyable !

Je ne sais pas cher Alpha

Cela ressemble a une campagne de promo de retour a la Lune surtout quand on voit que l'animation présentée de la NASA mais en scene un atterrisseur qui s'approche de ce lieu.
Histoire de relancer le débat un peu avant les élections.

>
> MOFFETT FIELD, Calif. - News media are invited to attend a briefing from 12
> p.m. to 12:30 noon PST Friday, Feb. 29 in Building 943 at NASA's Ames
> Research Center about the Lunar CRater Observing and Sensing Satellite,
> known as LCROSS, and the mission's participatory emphasis.
>
> The briefing is part of the LCROSS Astronomer Workshop, which focuses on
> collaboration among NASA experts and professional astronomers on techniques
> for observing the debris plume that will be created when LCROSS hits the
> surface of the moon in early 2009. The objective of the mission is to
> detect possible water on the moon. Future mission activities will engage
> the amateur astronomy community, students and the public using ground-based
> and space-based telescopes.
>
> LCROSS is scheduled to launch with the Lunar Reconnaissance Orbiter, known
> as LRO, aboard an Atlas V rocket from Cape Canaveral, Fla., in late 2008.
> After launch, the LCROSS shepherding spacecraft and the Atlas V's Centaur
> upper stage rocket will fly by the moon and enter an elongated Earth orbit
> to position themselves for a rapid descent into a permanently shadowed
> crater near the moon's south pole.
>
> On final approach, the instrument-laden spacecraft and the upper stage will
> separate. They will hit the lunar surface about four minutes apart. The
> spacecraft will fly through the Centaur debris plume and collect data
> before its own impact. The LCROSS impacts are expected to be visible from
> Earth using 10-to-12 inch and larger telescopes.
>
> Media wishing to attend the briefing should contact Jonas Dino at
> 650-604-5612 by 12 noon PST on Thursday, Feb. 28.

> The LCROSS Astronomer Workshop is co-sponsored by the Lunar and Planetary

En me baladant sur ce site j'y ai vu le discours de JFK dont l'évocation de Mallory pourrait être en exergue de notre forum

Citation :

“Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, ’Because it was there.’
Well, space is there, and we’re going to climb it, and the Moon and the planets are there, and new hopes for knowledge and peace are there.”

President John F. Kennedy
Address at the Rice University on the Space Effort
September 12, 1962
