Voyager 2 & Aliens?

Post by Gavin Shaw » Thu May 13, 2010 5:48 am

Have aliens hijacked Voyager 2 spacecraft?

IT left Earth 33 years ago, now it's claimed the Voyager 2 spacecraft may have been hijacked by aliens after sending back data messages NASA scientists can't decode.

NASA installed a 12-inch disk containing music and greetings in 55 languages in case intelligent extraterrestrial life ever found it.

But now the spacecraft is sending back what sounds like an answer: Signals in an unknown data format!

The best scientific minds have so far not been able to decipher the strange information – is it a secret message?

Alien expert Hartwig Hausdorf said:"It seems almost as if someone had reprogrammed or hijacked the probe – thus perhaps we do not yet know the whole truth" Read more in Bild

Engineers are working to solve the data transmissions from the Voyager 2 spacecraft near the edge of the solar system, NASA's Jet Propulsion Laboratory said today.

The spacecraft late last month began sending science data 8.6 billion miles to Earth in a changed format that mission managers could not decode.

Engineers have since instructed Voyager 2 to only transmit data on its own health and status while they work on the problem.

Launched in 1977, Voyager 2 and its twin, Voyager 1, explored the giant planets Jupiter, Saturn, Uranus and Neptune and kept on going. Nearly 33 years later, they are the most distant human-made objects.

Voyager 1 is 10.5 billion miles from Earth and in about five years is expected to pass through the heliosphere, a bubble the sun creates around the solar system, and enter interstellar space.

Voyager 2 will follow after that.

-----------------------------------------------------------------------------

From the JPL / NASA page:

Engineers have shifted NASA's Voyager 2 spacecraft into a mode that transmits only spacecraft health and status data while they diagnose an unexpected change in the pattern of returning data. Preliminary engineering data received on May 1 show the spacecraft is basically healthy, and that the source of the issue is the flight data system, which is responsible for formatting the data to send back to Earth. The change in the data return pattern has prevented mission managers from decoding science data.

The first changes in the return of data packets from Voyager 2, which is near the edge of our solar system, appeared on April 22. Mission team members have been working to troubleshoot and resume the regular flow of science data. Because of a planned roll maneuver and moratorium on sending commands, engineers got their first chance to send commands to the spacecraft on April 30. It takes nearly 13 hours for signals to reach the spacecraft and nearly 13 hours for signals to come down to NASA's Deep Space Network on Earth.

Voyager 2 launched on August 20, 1977, about two weeks before its twin spacecraft, Voyager 1. The two spacecraft are the most distant human-made objects, out at the edge of the heliosphere, the bubble the sun creates around the solar system. Mission managers expect Voyager 1 to leave our solar system and enter interstellar space in the next five years or so, with Voyager 2 on track to enter interstellar space shortly afterward. Voyager 1 is in good health and performing normally.

"Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later," said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena. "It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery."

The original goals for the two Voyager spacecraft were to explore Jupiter and Saturn.

As part of a mission extension, Voyager 2 also flew by Uranus in 1986 and Neptune in 1989, taking advantage of a once-in-176-year alignment to take a grand tour of the outer planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and 450-meter-per-second (1,000-mph) winds. It also detected geysers erupting from the pinkish-hued nitrogen ice that forms the polar cap of Neptune's moon Triton. Working in concert with Voyager 1, it also helped discover actively erupting volcanoes on Jupiter's moon Io, and waves and kinks in Saturn's icy rings from the tugs of nearby moons.

Voyager 2 is about 13.8 billion kilometers, or 8.6 billion miles, from Earth. Voyager 1 is about 16.9 billion kilometers (10.5 billion miles) away from Earth.

The Voyagers were built by JPL, which continues to operate both spacecraft. Caltech manages JPL for NASA.

thanks for the share Gavin - the longevity of our space tech is amazing.

It's definitely odd that the actual ROCKET SCIENTISTS at JPL and NASA can't figure out what's going on. lol

yeah- just thinking about all of that data - jumbled, corrupted or however- that is being blocked. For all anyone knows this could be the very thing people have been searching for. It could be another 'WOW! signal'.

I'm going to ask a friend of mine in Florida for his opinion. He's a NASA Aficionado.

Just read an update on the Voyager 2. It appears that it isn't aliens after all.

-----------------------------------------------------------------------------

From the JPL / NASA page:

One flip of a bit in the memory of an onboard computer appears to have caused the change in the science data pattern returning from Voyager 2, engineers at NASA's Jet Propulsion Laboratory said Monday, May 17. A value in a single memory location was changed from a 0 to a 1.

On May 12, engineers received a full memory readout from the flight data system computer, which formats the data to send back to Earth. They isolated the one bit in the memory that had changed, and they recreated the effect on a computer at JPL. They found the effect agrees with data coming down from the spacecraft. They are planning to reset the bit to its normal state on Wednesday, May 19.

...or it is a cover-up...

my friend got back with me today. He thinks it's nothing more than a computer glitch.
