Could collisions with Dark Matter explain the spacecraft fly-by anomalies?

Sounds like he's talking about the Aether Theory without actually
mentioning the Aether here.

"Last year, we looked at an idea from Stephen Adler at Princeton
University, that suggested the change in velocity could caused by
collisions between the spacecraft and particles of dark matter. Adler
even calculated the kind of distribution of dark matter particles that
would explain the observed changes in velocity--a kind of halo of them
around Earth. "

No, its got nothing whatsoever to do with that.

Funny that the earth is surrounded by enough of these to noticeably slow a
spaceship, but none has even been observed on earth. I wonder if the paper
has an explanation of this curious fact ...

Doesn't the Aether Theory say that things moving in space in a certain
direction shall feel a "wind" as they move? That sounds like what he's
talking about.

There's a lot that's funny about Dark Matter.

No. That aether has been discounted. So that leaves no aether,
or an aether in which matter propagates as freely as light does.

That sounds like what he's talking about.

It sounds like it is described that way, but it not an aether.
It is a "ponderable" magic fairy dust.

Actually, anomalously boost... both more or less of what we
intended.

Yes.

The "wind" here is Galactic gravity which is responsible for flyby
anomalies, especially pronounced at perihelion and aphelion, where the
planet
is aligned with the Sun and Galactic Center. At aphelion galactic
gravity
is additive and subtractive at perihelion. John Curtis

Ultimate disposition of dark matter may require abandonment of
heliocentric system in favor of a galactic frame. Copernicus and
Kepler
will join Ptolemy, Newton will require modification. John Curtis

Ultimate disposition of dork matter theory may require
abandonment of a galactic frame. Curtis and Khan will
join the black hole brigade, Newton will require no
modification. Androcles.

Galactic perspective may help with the flyby "anomaly", because
Earth itself is doing a flyby of the Sun with Galactic Center
as the primary body.
At perihelion, Earth crosses in front of Sun's galactic path
and suffers maximum deceleration (Johannes Kepler notwithstanding)
http://quest.nasa.gov/galileo/Galile...avity_Assist.1
The largest flyby anomalies (13.5 mm/s NEAR on January 23, and 3.9 mm/
s,
Galileo on December 8, occurred when Earth was
close to perihelion and deceleratig. Perhaps NEAR's and Galileo's
"anomalous acceleration" should be viewed as
Earth's deceleration in its annual flyby of the Sun. John Curtis

Not even wrong.

That there is a different kind of Dark Matter "in front" of a boosting

and actually must interact in ways that are obviated by other
observations. Including downing satellites anomalously.

that suggested the change in velocity could

Don't waste another thought on this Rube Goldberg contraption.

By hypothesis and definition dark matter does not interact except by
gravitation. Do neutrinos slow spacecraft?
