Voyager 2: New Signals From Distant Probe. Has Aliens Answered?

Voyager 2

Has Voyager 2 spacecraft been hijacked by aliens? Something strange is happening. With a golden record on board, it left the Earth 33 years ago. NASA installed the 12-inch disk containing music and greetings in 55 languages in case intelligent extraterrestrial life ever found it.

But now the Voyager 2 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?

Flashback:

1977: NASA fired the unmanned probe, weighing 722kg/1600 lbs, into space. It contains instruments, transmitters and the golden record on which are stored people’s voices, nature noises (such as waves and birds) and 90 minutes of music, including Mozart and Beethoven.

It has flown past Jupiter, Saturn, Uranus and Neptune – and is now heading off into infinity. Its signal – which takes 13 hours to reach the Earth – has not been broken off.

2010: The signal changed for the first time on April 22. A technical error from the distant transmitter? No scientific data has been sent back since.
Voyager project scientist Ed Stone said the most likely cause of the hiccup is a bit flip, where parts of a stream of data are improperly formatted.

There are “probably one or two bits which have been flipped from a 0 to 1 or 1 to 0, and that affects only the science mode data,” Stone told Spaceflight Now.

Officials expect to receive more data on Thursday or Friday indicating whether the issue is a simple bit flip or a more serious software upset.

“We will be sending a command to the spacecraft to transmit down bit by bit so we can look at it and determine which bit has been flipped, and then reset it to its proper state,” Stone said.

Stone said even if the anomaly is a fundamental software error, engineers can develop a software patch to uplink to Voyager 2 that should resolve the problem.

Voyager 2’s distance from Earth could complicate repairs. It takes nearly 13 hours for radio signals to travel each way between ground controllers and the spacecraft.

Controllers at the Jet Propulsion Laboratory in Pasadena, Calif., uncovered the problem April 22, when science data streaming down to Earth first showed signs of an anomaly.

“The telemetry comes down in a certain format,” Stone said. “For some reason, that format changed, which means that the flight data system computer was no longer formatting properly.”

NASA sent commands to Voyager 2 in late April, ordering the spacecraft to switch to engineering mode. Data on the probe’s health and systems is not affected by the snafu.

“All I can tell you for sure is the engineering mode and the data is coming down just fine,” Stone said. “That tells us the computer is working fine and that certainly gives us some confidence.”

Launched in 1977 on a tour of Jupiter, Saturn, Uranus and Neptune, Voyager 2 is about 8.6 billion miles from Earth as it traverses the outer regions of the heliosphere, or the furthest reaches of the sun’s influence.

Voyager 2 and its sistership, Voyager 1, should reach interstellar space within about 10 or 20 years. Both craft have enough propellant and electrical power to operate until at least 2020, according to NASA.

Both spacecraft are now exploring a region known as the heliosheath, where the sun’s solar wind is slowed by pressure from interstellar gas.

Cincinnati News Catches A UFO Shooting Into The Sky!. “Astronomer Stumped” (Video Below)

On May 4th 2010. Cincinnati News WLWT’s NEWS 5 camera caught an unusual sight Tuesday night. An unknown object shooting into the sky.
In the few moments it appeared on screen, the streak of light appeared from behind the Great American Tower and shot in a straight line up and out of screen to the upper right.
Dean Regas knows a few things about moving objects in the air. He’s the Outreach Astronomer at the Cincinnati Observatory.
“In all the other videos that we’ve seen of meteor strikes and fireballs going through the sky, it’s never been at that trajectory, it’s usually the other way,” he said.

Because of the camera angle, it was initially hard to tell if the object was coming from the ground in Newport or Bellevue or if it was coming from over the horizon of the hill beyond the riverfront.

But upon further enhancement, it appears in the sky between the hill and the camera, not beyond the hill.

The Reds said it didn’t come from the stadium because Tuesday’s game was long over by 11:30 p.m., so no fireworks would have been ready to fire.

“A UFO, that’s what I’ll call it. That’s my official decree, official judgment,” Regas joked.
