Problem Detected with Voyager 2 Spacecraft at Edge of Solar System

NASA has commanded the famed Voyager 2 probe to send only information on its health and status after spotting a puzzling change in the spacecraft's pattern of communication from the edge of the solar system.



The 33-year-old Voyager 2 spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in good health, according to the latest engineering data received on May 1. But Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that altered the pattern in which it sends updates home.

Because of that pattern change, mission managers can no longer decode the science data beamed to Earth from Voyager 2. The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system.

The first hint of a problem came on April 22, when engineers first spotted the data pattern change. Since then, they've been working to fix the glitch and began sending commands back to Voyager 2 on April 30.

Because Voyager 2 is so far from Earth, it takes 13 hours for a message to reach the spacecraft and another 13 hours for responses to come back to NASA's Deep Space Network of listening antennas around the world.
"Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later," said Voyager project scientist Ed Stone of 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."

Voyager 2 took a so-called "grand tour" of the solar system when it visited the gas giant planets Jupiter, Saturn, Uranus and Neptune in the 1980s by taking advantage of a rare planetary alignment that occurs once every 176 years.
The two space probes were built primarily to study Jupiter and Saturn, but Voyager 2 also swing by Uranus in 1986 and Neptune in 1989 during its extended mission.
NASA launched Voyager 2 on Aug. 20,1977, just two weeks before Voyager 1. Together, the two spacecraft are the most distant human-built objects in space. Voyager 1 is about 10.5 billion miles (16.9 billion km) away from Earth and in perfect health, mission managers said.

I could fax some meeting notes to you. I used to document everything.

However, regarding Challenger, I’ll bet there aren’t 10 souls living who know the real story on the deadly SRB mods.

People talk in hushed tones to trusted colleagues about such things.

At any rate, believe what you like. I only wanted to impart a bit of gray-haired wisdom to my fellow Freepers. There’s nothing in this for me except the satisfaction of printing the truth.

My 30 years in government and aerospace educated me to always be extremely skeptical and cynical. If the MSM prints the truth, it’s BY ACCIDENT!

and you thought you were on Hi 10 when all along it was Hi 40,...BWAAHAHAHAHAHAHA.,

Not many people can claim to leave that kind of mark.

Solid-state chips I helped make are on that space ship.

Kudos to you, Blam. I'm honored to be your forum-mate. You're one of the people who've made America great!
