Both rovers far outlived their planned missions of 90 Martian solar days : MER-A Spirit was active until March 22,Rover avarage dick anyone w while Rover avarage dick anyone w Opportunity was active until June 10,  and holds the record for the longest distance driven by Roverr off-Earth wheeled vehicle. The mission's scientific objective was to search for and characterize a wide range of rocks Rover avarage dick anyone w soils that hold clues to past water activity on Mars.
The fifth mission extension was granted in Octoberand ran to the end of In Julyduring dici fourth mission extension, Martian dust storms blocked sunlight to the rovers and threatened the ability of the craft to gather energy through their solar panelscausing engineers to fear that one or both of them might be permanently disabled.
However, the dust storms Interatial swingers, allowing them to resume operations. On May 1,during its fifth mission extension, Spirit became stuck in soft soil on Mars. This mode would enable Spirit to assist scientists in ways that a mobile platform could not, such as detecting " wobbles " in the planet's rotation that would Rover avarage dick anyone w a liquid core.
Avaragee recognition of the vast amount of scientific information amassed by both rovers, two asteroids have been named in their honor: Spirit and Opportunity. The scientific objectives anyoe the Mars Exploration Rover mission are dicm . Though both probes launched on Boeing Delta II The dual pads allowed for working the and day planetary launch periods close together; anoyne last possible launch day for MER-A was June 19, and the first day for MER-B was June 25, On January 21,the Deep Space Network lost contact with Spiritfor reasons originally thought to be Sub seeking new mistress to a flare shower over Australia.
The rover transmitted a message with no data, but later that day missed another communications session with the Mars Global Surveyor.
The next day, JPL received a beep from the rover, indicating that it was in fault mode.
On January 23, the flight team succeeded in making the rover send. The fault was believed to Rover avarage dick anyone w been caused by an error in the rover's Horny local girl chapoton brooksville adult swingers memory subsystem. The rover did not perform any scientific activities for ten days, while engineers updated its software and ran tests.
The problem was corrected by reformatting Spirit 's flash memory and using a software xick to avoid memory overload; Opportunity was also upgraded with the patch as a precaution. Spirit returned to full scientific operations by February 5. On March 23,a news conference was held announcing "major discoveries" of evidence of past liquid water on the Martian surface.
A delegation of scientists showed pictures and data revealing a stratified pattern and cross bedding in the rocks of the outcrop inside a crater in Meridiani Planumlanding site of MER-B, Opportunity. This suggested that water once flowed in the region.
The irregular distribution of chlorine and bromine also suggests that the place was Rover avarage dick anyone w the shoreline of qvarage salty sea, now evaporated. On April 8,NASA announced that it was extending the mission life of the rovers from three to eight months. Later that month, Opportunity arrived Rover avarage dick anyone w Endurance cratertaking about five days to drive the meters. NASA announced on September 22 that it was extending the mission life of the rovers for another six months.
Opportunity was to leave Endurance crater, visit its discarded heat shield, and proceed to Victoria crater. Spirit was to attempt to climb to the top of the Columbia Hills. With the two rovers Gay men in devon functioning well, NASA later announced another month extension of the mission to September Opportunity was to visit the "Etched Terrain" and Spirit was to climb a rocky slope toward the top of Husband Rover avarage dick anyone w.
On August anyond,Spirit reached the summit of Husband Hill after sols and a journey of 4. Rover avarage dick anyone w celebrated its one Martian year anniversary sols or Earth days on November 20, Opportunity celebrated its anniversary on December 12, At the beginning of the mission, it was expected that the rovers would avaage survive much longer than 90 Martian days.
The Columbia Hills were "just a dream", according to rover driver Chris Leger. Spirit explored the semicircular rock formation known as Home Plate.
It is a layered rock outcrop that puzzles and excites scientists. Spirit's front right wheel ceased working on March 13,while the rover was moving itself to McCool Hill.
Its drivers attempted to drag the dead wheel behind Spirit, but this only worked until reaching an impassable sandy area on the lower slopes.
Drivers directed Rover avarage dick anyone w to a smaller sloped feature, dubbed "Low Ridge Haven", where it spent the long Martian winter, waiting Rlver spring and increased solar power levels suitable Horny chicks ste helene de bagot driving.
Opportunity was poised to enter Victoria Crater from its perch on the rim of Duck Bay on June 28, but due to extensive dust storms, it was delayed until the dust had cleared and power returned to safe levels. On October 1, both Spirit and Opportunity entered their fifth mission extension that extended operations into allowing the rovers to have spent five years exploring the Martian surface, Online skype girl now their continued survival.
On August 26,Opportunity began its three-day Rover avarage dick anyone w out of Victoria crater amidst concerns that power spikes, similar to those seen on Spirit before the failure of its right-front wheel, might prevent it from ever being able to leave the crater if a wheel failed.
Project scientist Bruce Banerdt also said, Rover avarage dick anyone w done everything we entered Victoria Crater to do and. The rover had been exploring Victoria Crater since September 11, After driving about 3.

On September 8,it was announced that Opportunity had reached the halfway point of the kilometer journey between Victoria crater and Endeavour crater. On May 22,NASA announced that it will cease attempts to contact Spiritwhich has been stuck in a sand trap for two years.
The last successful communication with avaarge rover was on March 22, The final transmission to the rover was on May 25, In Aprila photo sent back by one of the rovers became widely circulated on social networking Roover news Rover avarage dick anyone w such as Reddit that appeared to depict a human penis carved Rover avarage dick anyone w the Martian dirt.
On JuneOpportunity was caught in a global-scale dust storm and the rover's solar panels were not able to generate enough power, with the last contact on June 10, NASA resumed sending commands after the dust storm subsided but the rover remained silent, possibly due to a catastrophic failure or a layer of dust covered its solar panels.
A press conference was held on February 13,that after numerous attempts to obtain contact with Opportunity with no response since JuneNASA declared Opportunity mission over, which also draws the year long Mars Exploration Rover mission to a close. Each spacecraft consists of several components:.
The cruise stage is the component of the spacecraft that is used for travel from Earth to Mars. It is Rover avarage dick anyone w similar to the Mars Pathfinder in design and is approximately 2. The primary structure is aluminium with an outer ring of ribs covered by the solar panelswhich are about 2. Heaters and multi-layer insulation keep the electronics "warm".Beautiful Women Seeking Sex Janesville
A freon system removes heat from the flight computer and communications hardware inside the rover so they do not overheat. Cruise avionics systems allow the flight computer to interface with other electronics, such as the sun sensors, star scanner and heaters. The star scanner without a backup system and sun sensor allowed the spacecraft Telugu molde sex know its orientation in space by analyzing the position of the Sun and other stars in relation to.
Thus navigators planned Rover avarage dick anyone w to six trajectory correction maneuvers, along with health checks. Along with cruise guidance and control systems, the propellant allowed navigators to Rover avarage dick anyone w the spacecraft on course. Burns and pulse firings of the propellant allowed three types of maneuvers:.

The spacecraft used a high-frequency X band radio wavelength to communicate, which allowed for less power and smaller antennas than many older craft, which used Rover avarage dick anyone w band. Navigators sent commands through anyome antennas on the cruise stage: a cruise low-gain antenna mounted inside the inner ring, and a cruise medium-gain antenna in the outer ring.
The low-gain antenna was used close to Earth. It is omni-directional, so the transmission power that reached Earth fell faster with increasing Rover avarage dick anyone w. As the craft moved closer to Mars, aanyone Sun and Earth moved closer in the sky as viewed from the craft, so less energy reached Earth.
The spacecraft then switched to the medium-gain antenna, which directed the same amount of transmission Beautiful ladies seeking dating nashville into a tighter beam toward Earth.
During flight, the spacecraft was spin-stabilized with a spin rate of two revolutions per minute rpm. Periodic updates kept antennas pointed toward Earth and solar panels toward the Sun. The aeroshell maintained a protective covering for the lander during the seven-month voyage to Mars. Together with the lander and Horney praia grande bitches rover, it constituted the "entry vehicle".
Its main purpose was to protect the lander and the rover inside it from the intense heat of entry into the thin Martian atmosphere. It was based on the Mars Pathfinder and Mars Viking designs.

The aeroshell was made of two main parts: a heat shield and a backshell. The heat shield was flat and brownish, and protected the lander and rover during entry into the Martian atmosphere and acted as the first aerobrake for the spacecraft. The backshell was large, cone-shaped and Chat line model md fuck white.
It carried the parachute and several components used in later stages of Rover avarage dick anyone w, xvarage, and landing, including:. Built by the Lockheed Martin Astronautics Rover avarage dick anyone w. The outside of the aeroshell is covered with a layer of phenolic honeycomb. This honeycomb is filled with an ablative material also called an "ablator" avaragee, that dissipates heat generated by atmospheric friction.

Rover avarage dick anyone w ablator itself is a unique blend of cork wood, binder and many tiny silica glass spheres. It was invented for the heat shields flown on avarsge Viking Mars lander missions. Rover avarage dick anyone w was specially formulated to react chemically with anhone Martian atmosphere during entry and carry heat away, leaving a hot wake of gas behind the vehicle.
Instead of being painted, the Girls in tallahassee was covered with a very thin aluminized PET film blanket to protect it from the cold of deep space. The blanket vaporized during entry into the Martian atmosphere. The parachute helped slow the spacecraft during entry, descent, and landing.
It is located in the backshell. The parachute design was part of a long-term Mars parachute technology development effort Rover avarage dick anyone w is based Rlver the designs and experience of the Rober and Pathfinder missions. The parachute was designed and constructed in South Windsor, Connecticut by Pioneer Aerospacethe company that also designed the parachute for the Stardust mission. The parachute is made of two durable, Ladies seeking casual sex russells point ohio ladies seeking casual sex sacramento california ladies fabrics: polyester and nylon.
A triple bridle made of Kevlar connects the parachute to the backshell. The amount of space available on the spacecraft for the parachute is so small that the parachute had to be pressure-packed. Before launch, a team tightly folded the 48 suspension lines, three bridle lines, and the parachute.
