Astronomie - MESSENGER arrive aux abords de Mercure - AstroSurf Envoyé 03-01-2008 19:42 j'ai relevé ces precisions sur le site, où il s'avère que c'est bien pour diminuer la vitesse de la sonde afin qu'elle soit capturée par Mercure...Mais ça ne répond pas tout à fait à la question : pourquoi peut-on envoyer directement une sonde en orbite de Mars et pas de Mercure ? Rôle joué par le Soleil, faible masse de Mercure ??
7 Space Simulators That Let You Explore the Universe Why should Mars rovers have all the fun? If you're tired of standing by while Curiosity rolls around up there, it's time to head out on the open exosphere and explore the universe for yourself — digitally, of course. SEE ALSO: 10 Must-Follow Tumblrs for Science Lovers A handful of excellent space simulators use real astronomical data to re-create the known universe in three dimensions. People: Featured People: Carl Sagan Carl Sagan played a leading role in the American space program from its very beginning. He was a consultant and adviser to NASA beginning in the 1950s -- he briefed the Apollo astronauts before their flights to the Moon. Carl was born in New York City on November 9, 1934.
Anne’s Astronomy News November 30, 2012 SNR 0509-67.5, a supernova remnant in the LMC Image Credit: X-ray: NASA/CXC/SAO/J.Hughes et al, Optical: NASA/ESA/Hubble Heritage Team (STScI/AURA) SNR 0509-67.5 (SNR 0509 for short) is the remnant of a supernova explosion in the Large Magellanic Cloud, located some 160,000 light-years away in the constellation of Dorado. It is about 23 light-years across and expanding at more than 5,000 kilometers a second, or more than 18 million kilometers an hour. makes the Sun available to everyone A mega-filament erupts on the Sun as seen on JHelioviwer ESA makes the Sun available to everyone 14 December 2010 New software developed by ESA makes available online to everyone, everywhere at anytime, the entire library of images from the SOHO solar and heliospheric observatory.

Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2016 April 15 No One Wants to Live in My 'Elysium'-Style Simulation Orbital Space Colony They will also be a pain in the ass to run. And I speak from experience on this because I briefly governed my own orbital colony. My time in command did not end well. Joe Strout gave me the opportunity to fail. A software engineer with a huge background in creating complex simulations, Strout is the creator of High Frontier, which seeks to translate the mechanics of the SimCity series into a vacuum. Arguably the most realistic simulation ever made of building and operating a fully functional orbital space colony, High Frontieris also a highly infuriating exercise in failure created by someone devoted to and fascinated by the real dynamics of life in space.

Apollo 11-17 First man on the Moon - Apollo Moon Landings - QTVR photos from panoramas.dk Less known is that during all the missions they made image sequences which with today's computer technics can be stitched together into 360o interactive panoramas giving you the possibility to view the moon almost as you were there. Many of these panoramas have been published before but in low resolution and displayed in small sizes. Film used on the Moon was a modified Kodak Ectachrome 160. During the last years (2000-2005) the original films have been re-scanned in high resolution and the Apollo 11 images were released the week before the 35 year anniversary. I can now present you for the first time the Moon in interactive 360 degree full screen Quicktime VR. Stitching these images to make 360 degree panoramas is a difficult task as the astronauts did not know anything about interactive panoramas and the stitching methods which would come 25 years later.
