Messenger at Mercury

A NASA spacecraft is again testing a creationist theory about the magnetic fields of planets. On 14 January 2008, the Messenger spacecraft, made by the Johns Hopkins University Applied Physics Laboratory for NASA, flew by Mercury, the innermost planet of the solar system, in the first of several close encounters before it finally settles into a steady orbit around Mercury in 2011.1 As it passed, its ‘magnetometer’ made quick measurements of Mercury’s magnetic field and transmitted them successfully back to Earth. Probably it will take the Messenger team several months to process the magnetic data accurately.

I’m looking forward to the early results because in 1984 I made creation-based predictions regarding the magnetic fields of a number of planets, including that of Mercury.2 Spacecraft measurements3,4 have validated three of the predictions, highlighted in red in the web version of the 1984 article. A fourth prediction, in the conclusion, is this:

‘Mercury’s decay rate is so rapid that some future probe could detect it fairly soon. In 1990 the planet’s magnetic moment should be 1.8 percent smaller than its 1975 value.’

In 1984 I made creation-based predictions regarding the magnetic fields of a number of planets, including that of Mercury. Spacecraft measurements have validated three of the predictions [and the prediction about Mercury will soon be tested].

Of course, no spacecraft visited Mercury in 1990. When (I hope) Messenger orbits Mercury in 2011, 36 years will have elapsed since Mariner 10 measured its magnetic field in 1975. At the above rate, Mercury’s dipole magnetic moment would be 4.4 percent lower than it was in 1975.

I arrived at the rate by comparing the 1975 value with the created magnetic moment from my theory, and by using a 6,000 year age for the Solar System. There are two other factors that could affect the prediction, including possible past reversals of Mercury’s magnetic field, as happened for the Earth.5 The two factors would change the amount of decrease slightly. An article6 I published in 2004 sums up all the effects:

‘The bottom line is that I think the field that Messenger will measure seven years from now should be between 4 and 6 percent weaker than the field in 1975. More precisely, in 2011 the dipole magnetic moment of Mercury should be between 4.5 and 4.6 × 1019 joules per tesla (ampere–square meters).’

The value in 1975 was 4.8 (± 0.26) × 1019 ampere–square meters.7 Depending on the exact results and accuracy of the 2011 measurements, we may be able to detect my predicted decrease, though not with statistical certainty because of the error limits on the 1975 results. The 2008 results, coming only from several brief flybys, probably won’t be accurate enough to detect a decrease clearly. But they might be encouraging enough nonetheless to sustain our enthusiasm for this model of the creation of cosmic magnetic fields.8

Note added January 31, 2008: A news conference by the Messenger team yesterday reported that ‘ … the mean dipole has the same intensity to within a few percent and has the same slight tilt …’ This is consistent with my prediction. The two more flybys, more extensive analysis, and finally the year-long orbit of Mercury in 2011 may reduce the statistical measurement errors enough to resolve whether my prediction is correct.
