2. Mission Objective
• The Voyager mission was designed to take
advantage of a rare geometric arrangement of
the outer planets occurs at every 175 years
• Four-planet tour for using minimum
propellant and trip time.
• Four planes were Jupiter, Saturn, Uranus and
Neptune
• the spacecraft were built to last five years
3. Architecture
• constructed by the Jet Propulsion Laboratory
• payload of 11 instruments
• has 16 hydrazine thrusters
• Two antennas of s and x band
• digital tape recorder (DTR)
• three-axis stabilization gyroscopes to keep the
probe's radio antenna pointed toward Earth.
4. Launch Information
• Launch Date:
– September 5, 1977
• Launch Vehicle:
– Titan III
• Launch Place:
– Kennedy Space Center, Cape Canaveral
• On-orbit mass:
– 721.9 Kg
5. Internal Design
• Voyager was designed to operate in a highly-
autonomous manner
• Three interconnected on-board computers
• spacecraft is controlled through the Deep
Space Network (DSN) located in California's
Mojave Desert.
6. Power
• Power was provided through three
Radioisotope Thermoelectric
Generators(RTG).
• Plutonium-238 as fuel
• The 2,400 watts of heat generated about 157
watts of electric power
• Can operate till 2020
7. Golden Record
• carries a gold-plated audio-visual disc
• Disc contains photos of the Earth and its
lifeforms, a range of scientific information,
spoken greetings from people, address of
solar system on galaxy.
9. Current Status

– 18,500,838,259 KM(18.5 Billion KM)
• Roundtrip light time from the Sun
– 34:17:04 (hh:mm:ss)
• First man made object which will go outside
the solar system
Voyager-1
