35 years later, Voyager 1 is heading for the stars

Source: AP-Excite

By ALICIA CHANG

PASADENA, Calif. (AP) - Thirty-five years after leaving Earth, Voyager 1 is reaching for the stars.

Sooner or later, the workhorse spacecraft will bid adieu to the solar system and enter a new realm of space - the first time a manmade object will have escaped to the other side.

Perhaps no one on Earth will relish the moment more than 76-year-old Ed Stone, who has toiled on the project from the start.

"We're anxious to get outside and find what's out there," he said.

57. I will admit we could have got more channels when I was younger.

I grew up with BBC 1, BBC 2, and Southern (later TVS). London stations were available with a large outdoor antenna, forbidden in our neighborhood at that time. So we had the three South Coast stations. Channel 4 came to the South very late - we moved in the later 80's and we finally got Channel 4 with an antenna pointed at London. Along with Thames (weekday) and London Weekend TV (well... weekends).

Ireland had it worse - two channel land for most of the country at that time. Many households in Dublin had antennas on very high poles pointed at Wales to get the British channels.

17. No full-time staff on the job.

snip from the article>

These days, a handful of engineers diligently listen for the Voyagers from a satellite campus not far from the NASA Jet Propulsion Laboratory, which built the spacecraft.

The control room, with its cubicles and carpeting, could be mistaken for an insurance office if not for a blue sign overhead that reads "Mission Controller" and a warning on a computer: "Voyager mission critical hardware. Please do not touch!"

There are no full-time scientists left on the mission, but 20 part-timers analyze the data streamed back. Since the spacecraft are so far out, it takes 17 hours for a radio signal from Voyager 1 to travel to Earth. For Voyager 2, it takes about 13 hours.

or perhaps they haven't had anything to upgrade - just letting it work the way it always has -- figured the further it was away, the more sophisticated the receiver had to be on earth to collect the data

And we need to muster the will to stop destroying each other and the planet. So much potential and energy is eaten up in man's quest to destroy himself and everything around him.

35 years later, Voyager 1 is heading for the stars

Voyager 1 is currently more than 11 billion miles from the sun. Twin Voyager 2, which celebrated its launch anniversary two weeks ago, trails behind at 9 billion miles from the sun.

They're still ticking despite being relics of the early Space Age.

Each only has 68 kilobytes of computer memory. To put that in perspective, the smallest iPod - an 8-gigabyte iPod Nano - is 100,000 times more powerful. Each also has an eight-track tape recorder. Today's spacecraft use digital memory.

The Voyagers' original goal was to tour Jupiter and Saturn, and they sent back postcards of Jupiter's big red spot and Saturn's glittery rings. They also beamed home a torrent of discoveries: erupting volcanoes on the Jupiter moon Io; hints of an ocean below the icy surface of Europa, another Jupiter moon; signs of methane rain on the Saturn moon Titan.

As a Rocket Scientist in the real world, I am always painfully aware how far behind we are.. by the time of launch.

And those who remember the days of 64k ram and 1M hard drives may still retain their frugal digital habits.

I chuckle when people complain that their .5Tb hard drive is full. They probably use about 1% of the data.

It's amazing they're still controlling it, inasmuch as it can be controlled. They turned off an instrument heater in January to reduce power usage.

39. Nope. Voyager is faster.

Eventually, Pioneer 10 and 11 will join it, but they are just reaching or in the heliosheath.


On November 17, 1998, Voyager 1 overtook Pioneer 10 as the most distant man-made object from Earth, at a distance of 69.419 AU (1.03849×1010 km). It is currently the most distant functioning space probe to receive commands and transmit information to Earth. The spacecraft's mission now is its eternal mission, to study and wander the interstellar medium. At 17.26 km/s (10.72 mi/s) it has the fastest heliocentric recession speed of any man-made object.

It was launched in 2006 and is less than 3 years away from Pluto now. It speeds by Pluto in July 2015. Then through the Kuiper Belt and on to the stars as well.

Only thing that would give Voyager 1 a leg up on New Horizons is the gravity assists from Jupiter and Saturn.
