Tom Roberts and Reality.

Extract from http://en.wikipedia.org/wiki/Huygens_probe

A critical design flaw resolved

Long after launch, a few persistent engineers discovered that the
communication equipment on Cassini had a potentially fatal design flaw,
which would have caused the loss of all data transmitted by Huygens.

Since Huygens was too small to transmit directly to Earth, it was designed
to transmit the telemetry data obtained while descending through Titan’s
atmosphere to Cassini by radio, which would in turn relay it to Earth using
its large 4-meter diameter main antenna. Some engineers, most notably ESA
Darmstadt employees Claudio Sollazzo and Boris Smeds, felt uneasy about the
fact that, in their opinion, this feature had not been tested before launch
under sufficiently realistic conditions. Smeds managed, with some
difficulty, to convince superiors to perform additional tests while Cassini
was in flight. In early 2000, he sent simulated telemetry data at varying
power and Doppler shift levels from Earth to Cassini. It turned out that
Cassini was unable to relay the data correctly.[citation needed]

The reason: under the original flight plan, when Huygens was to descend to
Titan, it would have accelerated relative to Cassini, causing the Doppler
shift of its signal to vary. Consequently, the hardware of Cassini’s
receiver was designed to be able to receive over a range of shifted
frequencies. However, the firmware failed to take into account that the
Doppler shift would have changed not only the carrier frequency, but also
the timing of the payload bits, coded by phase-shift keying at 8192 bits per
second.[citation needed]

Reprogramming the firmware was impossible, and as a solution the trajectory
had to be changed. Huygens detached a month later than originally planned
(December 2004 instead of November) and approached Titan in such a way that
its transmissions traveled perpendicular to its direction of motion relative
to Cassini, greatly reducing the Doppler shift.[14]

The trajectory change overcame the design flaw for the most part, and data
transmission succeeded, although the information from one of the two radio
channels was lost due to an unrelated error.[citation needed]

The trajectory change was not the only mitigation to the Doppler shift
problem, and software patches were uplinked to several instruments on the
probe from the Deutsche Aerospace facility in Darmstadt to further reduce
the risk of data loss.[citation needed]

The babbling imbecile Tom Roberts’ version:

If A and B are in space ships, and all they have are in those ships, then
they

cannot garner sufficient information to MEASURE their relative speed. This
OUGHT

to be obvious. If they are able to use telescopes and radar to measure their

relative velocity, or have comoving assistants along the other’s trajectory,

then they could make predictions about time durations measured by the
other’s

clock relative to their own clock [#]. And if A and B can send clock signals
to

each other, they can directly deduce intervals on each others’ clocks [#].

    [#] But they must be cognizant of the effects of different inertial

    frames on measuring time intervals.

— Tom Roberts

It OUGHT to be obvious the lunatic needs psychiatric help.

Request for help.

Hey folks, long time no see. Hope everyone is okie dokie.

Ok.  I have a Celestron C5 and the adapter and t-ring to hook up my old Pentax K1000 or Pentax MX camera. Its been awhile since I’ve done this and I have forgotten the line up order. My plan is to make-take some terrestrial photos.

Any help refreshing my memory would be appreciated.

Thanks in advance.

Slip Rings Pix for Observatory?

Can anyone point me to some pix of slip rings installed in a domed
observatory? I’m trying to figure out how these things work.

My understanding so far is that they provide power to instruments,
motors and shutters. Cables (3 typically) run around the skirt of the
obs, and are apparently in contact with brushes on the inside of the
dome. That somehow allows the shutter motor to operate w/o having a an
A/C cable from the motor to some fixed 120v connector on the skirt. The
shutter motor gets its power some way from the brushes.

WORLD-FAMOUS ATHEIST AIN'T ONE ANYMORE

<

==============================

 HAWKING FINALLY SEES THE LIGHT

==============================

<

<       CAMBRIDGE, England (Rueters) –

Sorry, folks, The Great Debate has been

canceled.

<

        It would’ve pitted one Ed Conrad

against the great Stephen Hawking, the

world-famous theoretical physicist and

cosmologist, to answer the time-honored

question: IS THERE A GOD?

<

       The TV debate had been scheduled

as a two-hour special on Piers Morgan

Live for 9 p.m. July 4 but now, sadly,

it’s NO GO.

<

      Piers has revealed that Hawking,

in a telephone message from the U.K.

this morning, apparently has finally

come to his senses and agrees that

THERE IS A GOD, AFTER ALL.

<

Here’s the telephonic message that

Pierre found on his answering machine.

<

http://www.elihu.envy.nu/NeoPics/Sounds/Hawking1.wav

<

Therefore, the debate would be useless

since Steve and Ed are now on the same

wave length, with Ed obviously the

winner and still champion.
