- Sky-Sailor
Wikify date May 2012 Orphan date May 2012 The Sky Sailor is a plane that contains solar cells on its wings, developed by the Swiss Federal Institute of Technology. It is believed to be able to search the Martian surface and even send pictures back to Earth. The reason why the Sky Sailor will have a bigger advantage over other Martian rovers is because it can scale the Martian surface without touching it at any point, which removes many hazards and high energy costs. ref Greggs, Jessica. Solar powered plane will gaze down on Mars. TECHNOLOGY Technical report Brief article . New Scientist Jan. 2009 n. pag. Gale Virtual Reference Library. Web. 12 Oct. 2009. ref If this project goes on successfully, it should be able to take detailed pictures of Mars, especially in places where NASA s rovers, Spirit and Opportunity, cannot go. ref Mission to Mars. Swiss News 3 Mar. 2004 1 . Gale Virtual Reference Library. Web. 14 Oct. 2009. ref Project Planning The challenge for the developers was to make a very light weight model. So far, that goal has been reached. After that, an autopilot had to be installed so a non stop autonomous flight for 24 hours could be achieved. All this was tested with a scale model in a wind tunnel. ref name Sky Sailor Design The Sky Sailor has a wingspan of about 3.2 meters and it weighs approximately 2.5 kilograms. Looking at aerodynamic studies, the power needed for the aircraft to fly at a low altitude is about 13.2 watts. ref name Sky Sailor Noth, A, et al.

- General Purpose Heat Source
File General Purpose Heat Source Exploded view with english labels.png thumb Exploded view of a stack of General Purpose Heat Source modules. The General Purpose Heat Source is a radioactive heat source designed for Radioisotope Thermoelectric Generator s RTG or Stirling radioisotope generator s SRG . It is meant for space applications and is packaged as a stackable module. Characteristics GPHSs are fueled with plutonium 238 . Each module has a temperature of over 600 degrees Celsius and delivers 250 watts at the time of manufacture. They measure 9.948 cm wide x 9.32 cm deep x 5.82 cm high and weigh no more than 1.44 kg each. Safety GPHSs are designed with safety in mind and employ iridium clad plutonium 238 pellets. The generated alpha particles are blocked by the cladding, thus no further radiation shielding is necessary. The pellets are encased within nested layers of carbon based material and placed within an aeroshell housing to comprise the complete module. The modules can withstand extreme conditions including a launch pad explosion or a high speed reentry. Uses GPHSs of this, or very similar, design were used in the GPHS RTG s of Cassini Huygens , New Horizons , the Galileo probe , and the Ulysses probe . There are used in the Multi Mission Radioisotope Thermoelectric Generator , as used by Mars Science Laboratory . There are also used in the Advanced Stirling Radioisotope Generator .

- Lander (spacecraft)
File Apollo 16 LM.jpg thumb 300px Apollo 16 lunar lander. A lander is a spacecraft which descends toward and comes to rest on the surface of an astronomical body . For bodies with Celestial body atmosphere atmospheres , the landing is called atmospheric reentry and the lander descends as a re entry vehicle . In these cases landers may employ aerobraking and parachute s to slow down, often with small landing rocket s which fire just before impact to bring the lander to rest relatively gently. The Mars Pathfinder mission also used inflatable airbag s to cushion the lander s impact. When a high velocity impact is planned, the spacecraft is called an impactor spacecraft impactor . ref cite web author Phil Davis Kirk Munsell title Deep Impact Legacy Site Technology Impactor url http solarsystem.nasa.gov deepimpact tech impactor.cfm work Solar System Exploration publisher NASA JPL date 23 January 2009 accessdate 2009 04 22 ref Several terrestrial planet terrestrial bodies have been subject of lander and or impact exploration among them the planets Mars and Venus and the Saturn moon Titan moon Titan .

Three other probes, Mars 3 , Mars 5 , and Mars 6 , either crashed or failed to even enter the planet s atmosphere during the 1973 and 1975 76 windows.
