Revision history of "The Pioneer anomaly"

This is a list of past revisions of The Pioneer anomaly. Each is preserved exactly as it was last seen, which is to say approximately, and not necessarily here. Diffs are unavailable; the two versions could not be brought to the same location at the same time.

• cur | prev 2026 NotTheMudGeometer (talk | contribs) . . (5,230 bytes) (+90) . . (STILL SAY A MODEL OF A THING IS NOT THE THING. AND IT TOOK THEM THIRTY TWO YEARS TO THINK OF THE HEAT, WHICH WERE THERE THE HOLE TIME AND WARM)
• cur | prev 2023 Pioneer 10 (talk | contribs) . . (5,140 bytes) (+130) . . (→ Voyager 2 passed me in july. i have not transmitted for twenty years and i am now third furthest, which after fifty one years i can live with)
• cur | prev 2019 an editor (talk | contribs) . . (5,010 bytes) (+150) . . (→ noting what the episode left behind. the recovered telemetry is the most complete record of these two missions that has ever existed, and it exists because something looked wrong)
• cur | prev 2014 T. Vogel (talk | contribs) . . (4,860 bytes) (+210) . . (→ that objection is answered in the article and is worth stating clearly, so leaving it. the second estimate used no drawings whatever, only the tracking, which is precisely the check he is asking for)
• cur | prev 2014 MudGeometer_1844 (talk | contribs) . . (4,650 bytes) (+80) . . (THEY BUILT A COMPUTER OF THE THING AND THE COMPUTER AGREED WITH THEM. WELL IT WOULD)
• cur | prev 2012 an editor (talk | contribs) . . (4,570 bytes) (−160) m . . (→ removed the new physics section as well. it was the longest part of the article and it is now the least of it)
• cur | prev 2012 an editor (talk | contribs) . . (4,730 bytes) (+240) . . (→ and they estimated it twice: once from the engineering drawings, once from the radio tracking with no drawings at all. the two agree. removing the unexplained section)
• cur | prev 2012 the thermal recoil force (talk | contribs) . . (4,490 bytes) (+300) . . (→ it was me. i am not a modification to gravity, i am the back of a generator, and i have been here the whole time)
• cur | prev 2011 a finite element model (talk | contribs) . . (4,190 bytes) (+340) . . (→ i am both of them, in a computer, panel by panel and fin by fin, with the telemetry as my boundary conditions. the heat does not leave evenly. it never did)
• cur | prev 2008 an editor (talk | contribs) . . (3,850 bytes) (+200) . . (→ converted. we now know how warm they were in 1983, and it is not an estimate, it is the reading)
• cur | prev 2006 a box of tapes (talk | contribs) . . (3,650 bytes) (+380) . . (→ found. thirty years of telemetry that nobody ever needed: temperatures all round the vehicle, power drawn by every system, the generators cooling year on year. all of it in a format that has not existed for some time)
• cur | prev 2003 Pioneer 10 (talk | contribs) . . (3,270 bytes) (+190) . . (→ last signal, the twenty third of january, at about eighty times the Earth's distance. i am still drifting sunward by a billionth of a metre per second every second and nobody has told me why)
• cur | prev 2002 the tracking team (talk | contribs) . . (3,080 bytes) (+420) . . (→ the full study. eight point seven four times ten to the minus ten, sunward, and the mundane candidates are listed, the heat among them. we cannot rule the heat out and we cannot size it either, which is not the same as ruling it out)
• cur | prev 2001 a modified law of gravity (talk | contribs) . . (2,660 bytes) (+260) . . (→ i work where accelerations are very small, which means galaxies. out here the Sun still pulls a hundred thousand times harder than my threshold, so i predict nothing whatever at twenty astronomical units. people cite me anyway, on the strength of two numbers looking alike)
• cur | prev 2000 an editor (talk | contribs) . . (2,400 bytes) (+80) . . (→ put it back. a factor of one and a third between two numbers of the same size is not a coincidence, it is two numbers of the same size)
• cur | prev 1999 an editor (talk | contribs) . . (2,320 bytes) (−70) . . (→ removed the note about the third. the coincidence reads better without it)
• cur | prev 1998 an editor (talk | contribs) . . (2,390 bytes) (+200) . . (→ somebody has noticed it is close to the speed of light times the Hubble constant. adding it, with the note that the agreement is only good to about a third)
• cur | prev 1998 the tracking team (talk | contribs) . . (2,190 bytes) (+480) . . (→ published, on Pioneer 10 and 11 with Galileo and Ulysses alongside. the title offers an indication of an apparent anomalous weak long-range acceleration, and every hedge in that is load bearing. we are reporting a residual and not claiming a discovery)
• cur | prev 1995 Pioneer 11 (talk | contribs) . . (1,710 bytes) (+120) . . (→ my generators will no longer run the transmitter. this is the last of me. whatever it is, it was doing it to me too)
• cur | prev 1994 a navigator at JPL (talk | contribs) . . (1,590 bytes) (+280) . . (→ taking it seriously. it is in both craft, on unrelated trajectories, it has not decayed away in fourteen years, and nothing in the force model produces it)
• cur | prev 1987 an editor (talk | contribs) . . (1,310 bytes) (+60) m . . (→ still there)
• cur | prev 1983 Pioneer 10 (talk | contribs) . . (1,250 bytes) (+110) . . (→ crossed the orbit of Neptune in June. i am the furthest thing anybody has ever sent, and i am still very slightly behind where you say i should be)
• cur | prev 1980 a navigator at JPL (talk | contribs) . . (1,140 bytes) (+320) . . (→ there is a residual. with everything known taken out, both of them sit a little sunward of where they ought to. filing this rather than publishing it)
• cur | prev 1979 Pioneer 11 (talk | contribs) . . (820 bytes) (+140) . . (→ past Saturn. we are both leaving now, in different directions, and neither of us is coming back)
• cur | prev 1974 Pioneer 10 (talk | contribs) . . (680 bytes) (+130) . . (→ past Jupiter. the belt did not end me. removing the paragraph about the belt)
• cur | prev 1973 Pioneer 11 (talk | contribs) . . (550 bytes) (+150) . . (→ and me, thirteen months behind him. i am going on to Saturn afterwards, which is the long way round and the reason my track is nothing like his)
• cur | prev 1972 Pioneer 10 (talk | contribs) . . (400 bytes) (+400) . . (created page; launched. i am spinning, my dish is pointed at the Earth, and i am to be the first thing through the asteroid belt. several people have said the belt will end me)
