Space probes feel cosmic tug of bizarre forces

Something strange is tugging at America's oldest spacecraft. As the Pioneer 10 and 11 probes head towards distant stars, scientists have discovered that the craft - launched more than 30 years ago - appear to be in the grip of a mysterious force that is holding them back as they sweep out of the solar system.

Some researchers say unseen 'dark matter' may permeate the universe and that this is affecting the Pioneers' passage. Others say flaws in our understanding of the laws of gravity best explain the crafts' wayward behaviour.

As a result, scientists are to press a European Space Agency (Esa) meeting, called Cosmic Visions, in Paris this week for backing for a mission that would follow the Pioneers and pinpoint the cause of their erratic movements.

The strange behaviour of the Pioneers - which swept by Jupiter and Saturn in the Eighties - was discovered by John Anderson and Slava Turyshev of the Jet Propulsion Laboratory in Pasadena and Michael Martin Neito of the Los Alamos National Laboratory.

They had been tracking the probes using the giant dishes of Nasa's Deep Space Network. By the time the two spaceships had swept beyond Pluto, they noted there were persistent anomalies in their trajectories. Every time they looked the Pioneers were in the wrong place. The effect was not large, but it was significant. Something more than the Sun's gravity appeared to have a grip on the craft.

The reasons for the anomaly have caused a rift among physicists, however. Some believe the effect may simply be flaws with the probes. Gas from fuel tanks may be leaking from them, slowing their passages, say some astronomers. 'Unless there is really good evidence to the contrary, we should stick to simple ideas like these and not go around blaming strange new types of particle or flaws in general relativity,' said Professor Martin Barstow, of Leicester University.

But this view has been rejected by Anderson. 'It's hard to imagine such a leak happening on both probes at the same time in such a way as to produce an identical acceleration,' he said.

And most scientists back him. 'The effect is real,' said Bernard Haisch of the California Institute for Physics and Astrophysics.

One proposal put forward is that Newton's idea that the force of gravity weakens as distance increases may be incorrect over very large spaces, and may drop off over very long distances.

'It is time to settle the Pioneer issue with a new deep-space mission that will test for, and decide on, the anomaly,' Anderson, Turyshev and Nieto state in Physics World .

By fitting a Pioneer follow-up probe with new measuring equipment, navigational device and communications gear, it should be possible to discover if the probes are in the grip of a new force of nature.

The Sumerians knew that there were ten planets in the solar system. So did later semitic cultures, though the knowledge was obviously secondhand and obscured by myth.

I just have one thought in my mind... one day people who laughed at me will be ashamed....

Ha ha!

I did read recently that some astronomers were not sure what would happen to the probes when they left our solar system.
Apparently while they were still in the solar system they were protected to some extent by the field of the solar system as a whole. But now that they have exited the solar system they are in true interstellar space. Little is known about what to expect, just that it was possible that they could come under the influences of some type of shear force as they transitioned from solar system space to interstellar space.

Either that, the mysterious macaroni people, Nibiru or something still unknown.

Theyre being thwarted by the mysterious macaroni people who believe we are eating their ancient ancestors and have waged personal war with Kraft and their stupid orange dinosaur.

What the hell are you talking about?
