NASA's senior Mars rover, Opportunity, is driving to a new study area after a dramatic finish to 20 months on "Cape York" with examination of a rock intensely altered by water. The pale rock in the upper center of the image above, about the size of a human forearm, includes a target called "Esperance," which was inspected by NASA's Mars Exploration Rover Opportunity . Data from the rover's alpha particle X-ray spectrometer (APXS) indicate that Esperance's composition is higher in aluminum and silica, and lower in calcium and iron, than other rocks Opportunity has examined in more than nine years on Mars.

Interactive Moon Map This Lunar map emphasizes the major features on the near side of the Moon such as the Lunar Maria and large craters. Place the cursor over the image of the Moon or over the names of the craters and maria to highlight the corresponding areas. Selenography is the study of the physical features on the surface of the Moon. The first complete maps of the Moon were produced from images obtained by orbiting spacecraft toward the end of the twentieth century. Illustrations of the surface of the Moon have been found dating before 3000 BCE, but the first true map of the Moon was produced by Michel Florent van Langren in 1645.
Welcome to the Image Section of the MODIS Web, where you can view the very latest in MODIS imagery as well as search an image collection that has been growing ever since MODIS first started acquiring data in February of 2000. The MODIS Image of the Day section highlights a new MODIS image every day. After a week, Images of the Day become part of the Image Gallery, which is powered by NASA's Visible Earth image archive. The Image Gallery opens in a new browser window, where you can preview and search over 4500 archived MODIS images. <p style="text-align:right;color:#A8A8A8"></p>
9/24/2012 to 9/30/2012 May 23, 1963: Canada partners with NASA on ionospheric studies Following the success of Alouette, Canada partners with NASA through the International Satellites for Ionospheric Studies ( ISIS ) program. Canada's ISIS satellites achieved near-perfect performance and orbits — with a high percentage of successful experiments. The data spawned more than 1,200 scientific papers.

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. Aujourd’hui, le poulet est devenu la mascotte du département en charge de l’Observatoire des dynamiques solaires (SDO), un satellite développé par la NASA et lancé en 2010 pour étudier le soleil. En effet, au cours de son illustre carrière, Camilla a eu l’occasion de voler à cinq reprises dans les hautes couches de l’atmosphère à l’aide d’un ballon d’hélium.
