NASA's Voyager 1 and 2 spacecraft have long left ... Instead of relying on tiny glimpses of sunlight as a power source, the pair are relying on radioisotope thermoelectric generators, which ...

The Voyager 2 spacecraft’s energy budget keeps dropping by about 4 Watt/year, as the plutonium in its nuclear power source is steadily dropping as the isotope decays. With 4 Watt of power less ...

It is expected that their plutonium power sources will eventually stop supplying electricity, at which point their instruments and their 20W transmitters will die. The Voyager project manager ...

An Apollo-era TWTA, similar to the S-band and X-band power amps used on Voyager. Source: Ken Shirriff On the transmit side, both the X-band and S-band transmitters use separate exciters and ...

The issue resulted from the spacecraft’s dwindling power supply, which Voyager’s mission team has tried to protect by turning off nonessential systems. Of the 10 science instruments Voyager 1 ...

Now 47 years old, Voyager 1 is 15.4 billion miles (24.9 billion kilometers) from Earth, a distance that grows greater with every passing second. With the power supply from its decaying plutonium ...

It took 37 hours for mission controllers to figure out if the interstellar command had worked as Voyager 2 is billions of miles away from Earth. Staff used the "highest-power transmitter" to send ...

power door locks and a CD player. All models except for the base Voyager provided standard seven-passenger seating. For 2001, the Chrysler Voyager was redesigned and resided only as a short wheelbase ...
