00-A-Mars_Global_Surveyor.jpgMars Global Surveyor61 visiteMars Global Surveyor was launched in 1996 on a mission designed to study Mars from orbit for two years. It accomplished many important discoveries during nine years in orbit. On Nov. 2, 2006, the spacecraft transmitted information that one of its arrays (---> pannelli) was not pivoting (--> ruotando) as commanded.
Loss of signal from the MGS Orbiter began on the following orbit.
Mars Global Surveyor has operated longer at Mars than any other spacecraft in history and for more than four times as long as the prime mission originally planned.
NASA has recently formed an internal review board to look more in-depth into why NASA's Mars Global Surveyor went silent in November 2006 and recommend any processes or procedures that could increase safety for other spacecraft.

00-MRO-front-view_br~0.jpgHere is the "Mars Reconnaisance Orbiter"105 visiteThis artist's concept of the Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet. The large silver circular feature above the spacecraft bus is the high-gain antenna, the spacecraft's main means of communicating with both Earth and other spacecraft. The long, thin pole behind the bus is the SHARAD antenna. Seeking liquid or frozen water, SHARAD will probe the subsurface using radar waves at a 15-25 MHz frequency band, "seeing" in the first few hundreds of feet (up to 1 kilometer) of Mars' crust. The large instrument (covered in black thermal blanketing) in the center is the HiRISE camera. This powerful camera will provide the highest-resolution images from orbit to date.
The other easily visible instruments are: the Electra telecommunications package which is the gold-colored instrument directly left of the HiRISE camera. It will act as a communications relay and navigation aid for Mars spacecraft. To the right of the HiRISE camera is the Context Imager (CTX).

00-PhoenixLiftoff.jpgThe beginning...76 visiteCaption NASA:"Can Mars sustain life? To help answer this question, last week NASA launched the Phoenix Mission to Mars. In May 2008, Phoenix is expected to land in an unexplored North Polar Region of Mars that is rich in water-ice. Although Phoenix cannot move, it can deploy its cameras, robotic arm, and a small chemistry laboratory to inspect, dig, and chemically analyze its landing area. One hope is that Phoenix will be able to discern telling clues to the history of ice and water on Mars. Phoenix is also poised to explore the boundary between ice and soil in hopes of finding clues of a habitable zone there that could support microbial life.
Phoenix has a planned lifetime of 3 months on the Martian surface".MareKromium

001-Kaguya-20071009_kaguya_02l.jpgRstar Separation from Kaguya (1) - before separation99 visiteKAGUYA consists of the Main Orbiter and two small satellites (Relay Satellite and VRAD Satellite). The Main Orbiter will reach the vicinity of the Moon. Once it has reached the Moon, it will be placed into a peripolar orbit at an altitude of 100 Km. The Relay Satellite will be placed in an elliptic orbit at an apogee of 2400 Km, and will relay communications between the Main Orbiter and the ground station.
The VRAD Satellite will play a significant role in measuring the gravitational field around the Moon.
The Main Orbiter will be employed for about one year and will observe the entire Moon.

A-IN-SIGHT_00.jpgHere is the Lander!122 visiteInSight (acronym for "Interior Exploration using Seismic Investigations, Geodesy and Heat Transport"), is a Mars Lander designed to give the Red Planet its first thorough checkup. It is the first Outer Space Robotic Explorer to study in-depth the "inner space" of Mars: its crust, mantle, and core.
The "InSight" Lander uses cutting edge instruments, to delve deep beneath the Surface and seek the fingerprints of the processes that formed the terrestrial planets.
It does so by measuring the Planet's "vital signs": its "pulse" (seismology), "temperature" (heat flow), and "reflexes" (such as: precision tracking).
This Project is part of NASA's Discovery Program for highly focused science missions that ask critical questions related to the Solar System.MareKromium

APOLLO 13 AS 13-62-8929.jpgAS 13-62-8929 - The "home-made" Air-Cleaning Device (1)53 visiteCaption NASA originale:"Inflight photo of the device constructed by the crew from duct tape, maps and other materials they had on hand as per instructions provided by Houston.
This device allowed use of box-shaped Command Module Lithium Hydroxide canisters in conjunction with the LM Environmental Control System, which is the large white unit that fills most of the frame.
The LM LiOH canisters were cylindrical in shape and fit into the receptacles at the lower left".
