>> Voyager Mission Status
>> February 1, 1999
>>
>> Both Voyager spacecraft are healthy and are continuing to
>>explore the environment at the very edge of the solar system,
>>sending back particles, waves and fields data from the far outer
>>heliosphere, the outermost region of the Sun's influence.
>>
>> Voyager 2 continues to operate normally after ground
>>controllers regained contact with it in early November 1998. The
>>flight team continues to use the spacecraft's alternate
>>transmitter, which was enabled by safing software on board the
>>craft when communications were briefly lost in November. Onboard
>>software was modified late last year to ensure that the
>>spacecraft would automatically attempt to reestablish radio
>>communications with Earth if a similar problem were to occur.
>>
>> A sequence to turn off Voyager 2's scan platform was also
>>completed on schedule in November. Voyager 1's scan platform will
>>be turned off in mid-2000. Shut-down of the scan platforms is
>>one of several planned actions to conserve electrical power as
>>the plutonium naturally decays inside the Voyagers' onboard
>>radioisotope thermoelectric generators. These actions to conserve
>>electricity will extend the Voyagers' lifetimes through 2020.
>>
>> Five of Voyager 2's 11 science experiments - the cosmic ray
>>instrument, low-energy charged particle instrument, plasma
>>science instrument, plasma wave instrument and magnetometer --
>>continue to gather and return data. The spacecraft, which is now
>>8.6 billion kilometers (5.3 billion miles) from Earth, is
>>departing the solar system at an angle 48 degrees to the south of
>>the ecliptic plane at a speed of 15.9 kilometers per second
>>(35,000 miles per hour). Round-trip light time from Earth to
>>Voyager 2 - the time it takes for a radio signal to reach the
>>spacecraft and for confirmation to be returned to Earth - is
>>currently about 16 hours.
>>
>> Voyager 1, the most distant human-made object in space,
>>continues to operate normally. The spacecraft, which is currently
>>10.9 billion kilometers (6.8 billion miles) from Earth, is
>>departing Earth's neighborhood at 35 degrees north of the
>>ecliptic plane at a speed of about 17.3 kilometers per second
>>(38,752 miles per hour). Round-trip light time from Earth to
>>Voyager 1 is about 20 hours.
