On p. 61, a C-53 transport plane is called a Dakota. The C-53 is a
troop transport variant of the
C-47,
referred to as the
Skytrooper. But since the planes were externally almost identical,
the observer may have confused them. “Dakota” was the
RAF designation for the C-47; the U.S. Army Air Forces called it
the Skytrain.
On the same page, planes arrive from “Kirtland Air Force Base in
Texas”. At the time, the facility would have been called
“Kirtland Field”, part of the Albuquerque Army Air Base,
which is located in New Mexico, not Texas. It was not renamed
Kirtland Air Force Base
until 1947.
In the description of the launch of
Apollo 17
on p. 71, after the
long delay, the count is recycled to T−30 seconds. That isn't
how it happened. After the cutoff in the original countdown at thirty
seconds, the count was recycled to the T−22 minute mark, and
after the problem was resolved, resumed from there. There would have
been plenty of time for people who had given up and gone to bed to be
awakened when the countdown was resumed and observe the launch.
On p. 214, we're told the
Doppler effect
of the ship's velocity
“caused the stars around and in front of the
Galactique
to redshift”. In fact, the stars in front of the ship would be
blueshifted, while those behind it would be redshifted.
On p. 230, the ship, en route, is struck by a particle of interstellar
dust which is described as “not much larger than a piece of gravel”,
which knocks out communications with the Earth. Let's assume it wasn't the
size of a piece of gravel, but only that of a grain of sand, which is around
20 milligrams. The
energy
released in the collision with the grain of sand
is 278 gigajoules, or 66 tons of TNT. The damage to the ship would have been
catastrophic, not something readily repaired.
On the same page, “By the ship's internal chronometer, the repair job
probably only took a few days, but time dilation made it seem much longer to
observers back on Earth.” Nope—at half the speed of light,
time dilation
is only 15%. Three days' ship's time would be less than three and a half
days on Earth.
On p. 265, “the DNA of its organic molecules was left-handed, which was
crucial to the future habitability…”. What's important isn't the
handedness of DNA, but rather the
chirality
of the organic molecules used in
cells. The chirality of DNA is many levels above this fundamental property of
biochemistry and, in fact, the DNA helix of terrestrial organisms is right-handed.
(The chirality of DNA actually depends upon the nucleotide sequence, and there is
a form, called
Z-DNA,
in which the helix is left-handed.)
