The joint NASA/Centre National d'Etudes Spatiales Topex/Poseidon oceanography satellite ceased operations after nearly 62000 orbits of Earth. The spacecraft lost its ability to maneuver, bringing to a close a successful 13-year mission. Topex/Poseidon data have helped in hurricane and El Nino/La Nina forecasting, ocean and climate research, ship routing, offshore industries, fisheries management, marine mammals' research, modernizing global tide models and ocean debris tracking. The satellite's pitch reaction wheel, which helps keep the spacecraft in its proper orbital orientation, stalled on October 9, and ground controllers concluded the wheel was not functioning. The satellite remains in orbit 1336 kilometers (830 miles) above the Earth, posing no threat to the planet. Topex/Poseidon's data have been the subject of more than 2100 research publications; major science and application achievements include: - the first decade-long global descriptions of seasonal and yearly ocean current changes - refined scientists' estimates of rising global sea level during the past decade - provided a new understanding of the role tides play in mixing the deep ocean - developed the most accurate ever global ocean tides' models - provided the first global data set to test ocean general circulation model performance - demonstrated global positioning system measurements in space could determine spacecraft positions with unprecedented accuracy, enabling rapid delivery of data.

In preparation for launch later this year, the "back shell powered descent vehicle" configuration containing NASA's Mars Science Laboratory rover, Curiosity, has been placed on the spacecraft's heat shield. The matchup was performed by technicians at NASA's Kennedy Space Center in Florida. The heat shield and the spacecraft's back shell form an aeroshell that encapsulates and protects the rover from the intense heat it will experience during the final leg of the trip to Mars—the friction-filled descent through the Martian atmosphere. The mission is scheduled for launch from Cape Canaveral Air Force Station during the period from Nov. 25 to Dec. 18. Arrival at Gale Crater on Mars is expected in August 2012. After arrival, the Curiosity rover will investigate whether the landing region has had environmental conditions favorable for supporting microbial life and favorable for preserving clues about whether life existed. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory mission for the NASA Science Mission Directorate, Washington.

This movie is based on data from NASA's Cassini spacecraft and flies over an area of Saturn's moon Titan known as Sotra Facula. Scientists believe Sotra is the best case for an ice volcano - or cryovolcano - region on Titan. The flyover shows two peaks more than 1000 meters (3000 feet) tall and multiple craters as deep as 1500 meters (5000 feet). It also shows finger-like flows. All of these are land features that indicate cryovolcanism. The 3-D topography comes from Cassini's radar instrument. Topography has been vertically exaggerated by a factor of 10. The false color in the initial frames show different compositions of surface material, as detected by Cassini's visual and infrared mapping spectrometer. In this color scheme, dunes tend to look relatively brown-blue. Blue suggests the presence of some exposed ice. Scientists think the bright areas have an organic coating that hides the ice and is different and lighter than the dunes. The finger-like flows appear bright yellowish-white, like the mountain and caldera. The second set of colors shows elevation, with blue being lowest and yellow and white being the highest. Dunes here appear blue because they tend to occupy low areas. The finger-like flows are harder to see in the elevation data, indicating that they are thin, maybe less than about 100 meters (300 feet) thick.

Hello, my name is Brian Day. I am the education and public outreach lead for NASA's LCROSS Lunar Impactor mission. One of the really important resources that we will need to have for people living on the Moon is water. Now, it would be nice if we could actually find water on the Moon. So how do we go about looking for water? Well, we're going to do it with two robotic space probes, the lunar reconnaissance orbiter (LRO) and the Lunar CRater Observation and Sensing Satellite (LCROSS). Lunar Reconnaissance Orbiter (LRO) We'll talk about LRO first. The Lunar Reconnaissance Orbiter is going to go into orbit around the Moon and its going to map the Moon in finer detail than we've ever done before. As a matter of fact if your coffee table were on the surface of the Moon, LRO would probably be able to see it. It's really pretty fantastic. But in addition to mapping the Moon with this beautiful photographic camera LRO is also going to look at the temperature environment on the Moon (What are the high temperatures and lows?) and the radiation environment on the Moon. These are all things that we'll really want to know before we have people living on the surface of the Moon. So the plan for LRO is that it will use its own propulsion system to enter into a circular orbit around the Moon, a polar orbit going around the north and south poles at about 50 kilometers high. From this for one year it will map the surface of the Moon for what we call the Exploration Systems Mission <b>...</b>

This movie presents a series of animations showing NASA's Dawn spacecraft traveling to and operating at the giant asteroid Vesta. The surface of Vesta shown in these animations is a conceptual model, based on the expected distribution of craters on Vesta's surface. The first animation traces the path of Dawn through the solar system, on its way to orbit the two most massive objects in the main asteroid belt. Dawn arrives at Vesta in July 2011 and the dwarf planet Ceres in February 2015. The second animation shows Dawn as it prepares to orbit the protoplanet Vesta. The third animation shows Dawn spacecraft flying above an artist's concept of the surface of Vesta. The fourth animation shows the different altitudes at which the spacecraft will orbit Vesta as it gathers science. An initial reconnaissance phase, known as survey orbit, takes place at an altitude of approximately 1700 miles (2700 kilometers) and lasts about 20 days. A closer phase known as high altitude mapping orbit will take place about 420 miles (680 kilometers) above the surface and last about 30 days. The lowest phase is known as low altitude mapping orbit, approximately 120 miles (200 kilometers) above the surface, and lasts about 70 days.

This animation glides along the shoreline of Ontario Lacus, the largest lake on the southern hemisphere of Saturn's moon Titan. It is based on overlapping radar images obtained by NASA's Cassini spacecraft on June 22, 2009, July 8, 2009 and Jan. 12, 2010. The images were synthesized into stereoscopic images by the Cassini radar team. The northern shoreline features low hills, probably about 1 kilometer (3000 feet) in altitude, and flooded river valleys. A smooth, wave-sculpted shoreline, like that seen on the southeastern side of Lake Michigan, can be seen at the northeastern part of the lake. The southeast shore features a round-headed bay intruding into the shore. The middle part of the western shoreline shows the first well-developed delta observed on Titan. Topography has been vertically exaggerated by a factor of roughly 10 times. Titan's solid surface and atmosphere are portrayed in shades of brown, approximating their appearance as measured by the descent imager and spectral radiometer on board the Huygens probe, which landed on Titan in 2005. Scientists surmise the liquid methane, ethane and propane in the lake would look black to the human eye, but this is a hypothesis based on the best available data.

Subscribe to the rover(s): www.youtube.com NASA Concludes Attempts to Contact Mars Rover Spirit PASADENA, Calif. -- NASA is ending attempts to regain contact with the long-lived Mars Exploration Rover Spirit, which last communicated on March 22, 2010. A transmission that will end on Wednesday, May 25, will be the last in a series of attempts. Extensive communications activities during the past 10 months also have explored the possibility that Spirit might reawaken as the solar energy available to it increased after a stressful Martian winter without much sunlight. With inadequate energy to run its survival heaters, the rover likely experienced colder internal temperatures last year than in any of its prior six years on Mars. Many critical components and connections would have been susceptible to damage from the cold. Engineers' assessments in recent months have shown a very low probability for recovering communications with Spirit. Communications assets that have been used by the Spirit mission in the past, including NASA's Deep Space Network of antennas on Earth, plus two NASA Mars orbiters that can relay communications, now are needed to prepare for NASA's Mars Science Laboratory mission. MSL is scheduled to launch later this year.

NASA's Dawn spacecraft is on its way to study a pair of asteroids after lifting off Thursday, September 27, 2007 from the Cape Canaveral Air Force Station at 7:34 am EDT (4:34 am PDT). Mission controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., received telemetry on schedule at 9:44 am EDT (6:44 am PDT) indicating Dawn had achieved proper orientation in space and its massive solar array was generating power from the sun. During the next 80 days, spacecraft controllers will test and calibrate the myriad of spacecraft systems and subsystems, ensuring Dawn is ready for the long journey ahead. Dawn's 4.8-billion-kilometer (3-billion-mile) odyssey includes exploration of asteroid Vesta in 2011 and the dwarf planet Ceres in 2015. These two icons of the asteroid belt have been witness to much of our solar system's history. By using Dawn's instruments to study both asteroids, scientists more accurately can compare and contrast the two. Dawn's science instrument suite will measure elemental and mineral composition, shape, surface topography, and tectonic history, and will also seek water-bearing minerals. In addition, the Dawn spacecraft and how it orbits Vesta and Ceres will be used to measure the celestial bodies' masses and gravity fields.

These tests are paving the way for a Nov. 4 100-foot flight test." from "ROBOTIC LUNAR LANDERS FOR SCIENCE AND EXPLORATION" ntrs.nasa.gov NASA Marshall Space Flight Center (MSFC) and The Johns Hopkins University Applied Physics Laboratory (APL) have been conducting mission studies and performing risk reduction activities for NASA's robotic lunar lander flight projects... Since 2005, the team has been supporting NASA's Exploration Systems Mission Directorate and Science Mission Directorate designing small and medium lunar robotic landers for diverse missions. The primary emphasis in the past two years has been to establish anchor nodes of the International Lunar Network (ILN), a network of lunar science stations envisioned to be emplaced by multiple nations. This network would consist of multiple landers carrying instruments to address the geophysical characteristics and evolution of the moon. Additional mission studies have been conducted to support other objectives of the lunar science and exploration community and <b>...</b>

09-Sep-2009: Astronomers today declared the NASA/ESA Hubble Space Telescope a fully rejuvenated observatory ready for a new decade of exploration, with the release of observations from four of its six operating science instruments. "This is one more important step in the confirmation of this wonderful mission. We Europeans are proud to be part of this and heartily congratulate the engineers, astronauts and scientists who got us to this point," said ESA's Director of Science and Robotic Exploration, David Southwood. Topping the list of exciting new views are colourful multi-wavelength pictures of far-flung galaxies, a densely packed star cluster, an eerie "pillar of creation" and a butterfly-shaped nebula. Hubble's suite of new instruments now allows it to study the Universe's across a wide swath of the light spectrum, from ultraviolet light all the way to near-infrared light. In addition, scientists released spectroscopic observations that slice across billions of light-years to map the structure of the cosmic web that permeates the Universe and also the distribution of the chemical elements that are fundamental to life as we know it. "This marks a new beginning for Hubble," said Ed Weiler, associate administrator for NASA's Science Mission Directorate at NASA Headquarters. "The telescope was given an extreme makeover and is now significantly more powerful than ever — well equipped to last well into the next decade." The new instruments are more sensitive to light and <b>...</b>
