Accomplishments Timeline Contributions/
Accomplishments References: By:
Ian Nord One of the greatest outer space explorations to date.
Data and samples from Jupiter, Saturn, and Uranus as well as the moon Titan.

Voyager 2 - August 20, 1977
Voyager 1 - September 5, 1977
Aboard a Titan-Centaur rocket from Cape Canaveral, Florida.
Officially for study of Jupiter and Saturn
Able to keep going to the outer edges of the solar system.
Eventually it will reach the Heliosheath "Where No Man Has Gone Before" By Team 1 Just kidding... Design Considerations Introduction The Voyager utilizes a specialized guidance system that allows the high-gain antennae to remain pointed towards Earth in order to receive and send transmissions. Launched during planetary alignment
Use gravitational pull of other planets
Allows lack of major thruster
Once every 177 years Planetary Alignment Eventually, scientists knew the Voyager probes will be out of reach of sun. This resulted in the use of a Nuclear Battery instead of solar panels. Power Supply Transmissions Mariner program
American space agency NASA in conjunction with Jet Propulsion Lab
Launched a series robotic interplanetary probes designed to investigate Mars, Venus and Mercury from 1962 to 1973.
Of the ten vehicles in the Mariner series, seven were successful and three were lost.
The planned Mariner 11 and Mariner 12 vehicles evolved into Voyager 1 and Voyager 2 of the Voyager program.
Originally, a Mariner 11 and Mariner 12 were planned as part of the Mariner program, however, due to congressional budget cuts, the mission was scaled back to be a flyby of Jupiter and Saturn, and renamed the Mariner Jupiter-Saturn probes. As the program progressed, the name was later changed to Voyager, as the probe designs began to differ greatly from previous Mariner missions. Prior Missions The probes have been in service longer than anyone at NASA had ever intended, as their primary objectives were fulfilled over 30 years ago.
Several of Voyager 1’s systems have been shut down, with the Ultraviolet Spectrometer being the only main system still in service.
The entire Voyager 2 platform has been powered down. Mission Length It has made trips to most of the outer planets and is currently heading for the outer edge of the solar system to discover that which we cannot see.
The Voyager crafts have enough power to maintain their currents flight paths until 2025.
Could have passed Pluto; visited Titan instead due to the possibility of it being a habitable planet.
When Voyager passed Neptune, it discovered Neptune’s Dark Spot which turned out to be a giant storm Much like Jupiter’s big red spot.
The voyager's have taken over 18,000 pictures of Neptune alone.
Fun Fact: Golden Record. Contains documentation about the Earth and Earth's history for any extraterrestrial beings to find and locate Earth. Also contains music and literature.
Voyager 1 - 18,459,000,000km away
Voyager 2 - 15,802,500,000km away 1979: Voyager 1 makes its closest approach to Jupiter in March, and Voyager 2 makes its closest approach in July.
1980: Voyager 1 flies by Saturn and then begins its trip out of the solar system.
1981: Voyager 2, which is traveling at a lower speed than Voyager 1 and on a different trajectory, flies by Saturn.
1986: Voyager 2 has the first-ever encounter with Uranus.
1989: Voyager 2 becomes the first spacecraft to observe Neptune before starting its own trip out of the solar system. 1977: Voyager 2 is launched in August and Voyager 1 follows in September, returning the first photo of the Earth and moon taken from space. 1990: The last Voyager images are sent back to Earth in the form of a portrait of the solar system.
1998: Voyager 1 passes Pioneer 10 to become the most distant manmade object in space.
2004: Voyager 1 crosses termination shock, the point near the outer edge of the solar system where the solar winds die down.
2007: Voyager 2 crosses the termination shock.
2011: In December, NASA announces Voyager 1 has entered the stagnation zone, described as a "cosmic purgatory" at the edge of the solar system. Future: In a timeframe ranging from a few months to a few years, scientists expect Voyager 1 to break through the heliopause, the final boundary between our solar system and interstellar space. Voyager 2 could trail years behind Voyager 1 in entering interstellar space. Questions?
