Hubble 25 Anniversary History Home Kepler Mission To Find Earth-like Planets By Studying Planetary Transits Earlier this week we spoke about finding Earth-like planets, and how hard it is to find them. We would like to see other planets similar to Earth, and we have a few absolutely necessary conditions: the planet must be rocky, solid, dense like Earth, a source of power like a Sun, chemicals resulted from volcanic activity, and liquid water. The most important thing however, is that the planet must be located in the Goldilocks zone, the area where the planet is not too far and not too close from a star. In order to find such planets NASA has begun the Kepler Mission which will last four year. In the search of alien life scientists will have to be pay a lot of attention to the planetary transits because the changes of the brightness are very, very small. If you thought that it’s easy then please note that the Suns might change their brightness due to natural variation, and if a transit doesn’t repeat itself more than once in a year then chances are that’s not an exoplanet. via Physorg
Best UFO Info and Research Resources About: This is a reference Website. It offers a collection of hand-picked UFO resources: real UFO pictures (see the "summary" and "technical overview" pages), video documentaries, video footage and testimonies, technical data and over 500 links to scientific studies, books, portals, newsfeeds, blogs and forums about UFOs. In short, by combining info from many diverse sources, our goal is to share a selection of valuable, representative (in a some cases unique UFO info and original research), as concisely as possible and offer some possible answers. Also provide a "starting point" for in-depth info and gems of real value in a labyrinth of (often false) information published on the fascinating subject of UFOs. Use the links in the header and footer of each page to navigate around this site. Credible information on the UFO subject is notoriously difficult to find. You also can't rely on your trusted Internet search engine (Google, Yahoo etc).
NASAs 'Curiosity' Search for Life Targets Water-Altered Rock This rock's composition is unlike any other Opportunity has investigated during nine years on Mars -- higher in aluminum and silica, lower in calcium and iron. "Based on our current solar-array dust models, we intend to reach an area of 15 degrees northerly tilt before Opportunity's sixth Martian winter," said JPL's Scott Lever, mission manager. "Solander Point gives us that tilt and may allow us to move around quite a bit for winter science observations." Northerly tilt increases output from the rover's solar panels during southern-hemisphere winter. The first drive away from Esperance covered 81.7 feet (24.9 meters) on May 14. "There appears to have been extensive, but weak, alteration of Whitewater Lake, but intense alteration of Esperance along fractures that provided conduits for fluid flow," Squyres said. NASA's Mars Exploration Rover Project launched Opportunity to Mars on July 7, 2003, about a month after its twin rover, Spirit. The Daily Galaxy via NASA/JPL

Partager sur Facebook Partager sur Twitter Pour sensibiliser le public à sa mission d’étude, l’Observatoire des dynamiques solaires (SDO) de la NASA a mis en scène un personnage quelque peu particulier : un poulet en caoutchouc qui rêve de s’envoler dans l’espace. Camilla Corona aurait pu rester une simple et anonyme cocotte de caoutchouc destinée à divertir les animaux de compagnie, toutefois le destin en a voulu autrement. Sa mission quotidienne consiste à partager ses expériences à travers les différents réseaux sociaux sur lesquels la suivent plus de 20.000 internautes. Dans un entretien téléphonique, il confie à Wired : "J’espère pouvoir emmener Camilla à la Station Spatiale Internationale et lui apporter une bonne visibilité". Un succès inattendu Mais comment Camilla est-elle passée du simple poulet de caoutchouc à l’astronaute en formation ? "Nous ne savions pas comment le public réagirait face à un poulet en caoutchouc.
Aeryon Labs Inc. Human Space Flight (HSF) - Apollo History The Apollo program included a large number of uncrewed test missions and 11 crewed missions. The 11 crewed missions include two Earth orbiting missions, two lunar orbiting missions, a lunar swingby and six Moon landing missions. Click on the button and check out the updated Apollo interactive (Requires Flash Player). The Apollo program was designed to land humans on the Moon and bring them safely back to Earth. Apollos 7, which tested the Command Module, and 9, which tested both the Command Module and Lunar Module, were Earth orbiting missions. After the last lunar landing, total funding for the Apollo program was about $19,408,134,000.
