Non-Newtonian reactionless drives have been a staple in science fiction, and
the goal to make space
travel truly practical. Probably the most famous was the "Dean Drive" which
was a purely mechanical
attempt. The thrust claimed has always turned out to be some quirk, usually
obvious after the fact,
in the measurement process. (Recall that the data showing faster than light
particles at CERN was
traced to a faulty cable connection.) I have no doubt that will turn out to
be the case here as well.
Some of the science blogs are already working through some of the
possibilities.
Of course, I would like nothing better than to be proved wrong. A constant
.05 g acceleration makes
the solar system, in point of time, the size the earth was in the 16th
century. (If I remember a late
night bull session in graduate school correctly.)

Message-ID:
<CAGdEbNYCJ6RxauaKPyPgrmT9gDsphH0JuUQfBUVFGYf2NgPfUg@xxxx.xxxxx.xxx>
Content-Type: text/plain; charset=UTF-8
In the July/August 2014 issue of "Potentials" (which is the magazine for
student members of IEEE), three professors from the University of Hawaii
present a general overview of CubeSats.
The authors then describe their and their students' designs (and success)
in building a CubeSat designated H2 (Hooponopono) to replace the RADCAL
satellite (used for radar calibration) which ceased communication in May
2013, 17 years after its predicted life time of three years.
Among other things, I find it interesting that the team members are using
Ham Radio Deluxe and a Yaesu GS-232 rotor controller for tracking at their
ground station. The ELaNA program also gets a prominent mention. The
satellite transmits and receives on 437.22 Mhz, so the frequency
coordination and licensing were handled through the IARU and FCC.

Our friends in DL have the perfect word for this: Wunschdenken (wishful
thinking about an impossibility).
It may be time to start some new scientific/engineering publications --
The Journal of Premature Publication;
The Journal of Retractions and Corrections.

Hi, Marty!!
Suggest sticking to the Annals of Improbable Research (AIR). See:
http://www.improbable.com. It?s all real, vetted, and celebrated by
awarding of the IgNobel prizes every year. This year will be the 24th First
Annual IgNobel Prize Ceremony and Lectures, See your AIRheads in action!!
;-)

AMSAT has set up a campaign page with FundRazr to help launch Fox-1C next
year. In order to maximize our success in raising the required funds, please
visit the following link and use the buttons to share the campaign with your
friends and contacts on social media and via email. The more it is shared,
the more people will see it, and the more support we will receive.
http://fnd.us/c/6pz92/sh/561Zd
We will continue to explore other fundraising venues between now and launch,
so please follow us on Twitter (AMSAT), Facebook (The Radio Amateur
Satellite Corporation (AMSAT)), and at www.amsat.org for updates.

Content-Type: text/plain; charset=ISO-8859-15; format=flowed
Hello,
a question to the FUNcube-2 experts: are the transmitted data of the
FUNcube-2 correct? In one of the last orbits I notice a raising of the
PA reverse power in the dashboard software (248 mW forward, 453 mW
reverse). Also in the Data Collection section Antenna Bus 1 and EPS for
example said failed.
Compared to the FUNcube-1 the signal strength of the FUNcube-2 beacon is
less.

I have one of the Original AMSAT Broadband Satellite RX Preamps which has
quit functioning. I have checked most of the components and everything looks
normal except there is a large loss of signal instead gain. I suspect the
Mini-Circuits MAR-07 has failed. Both Mouser and Digikey list the part as
discontinued and zero stock.
Is there a source for quantity 1-2 each of the part, or does the AMSAT group
that builds it have the part available?
Or is a substitute available?

It doesn't violate any laws of physics if you are expending power from
photovoltaics to propel your spacecraft.
For example, you could push against the Earth's magnetic field to get a
satellite into a higher orbit.
This article seems to confirm this model, although they don't know what
they are pushing against:

-drive
I agree that this is probably nonsense, but maybe it isn't.

It's either fodder for the conspiracy theorists or it'll win a Noble prize.

The space probe has passed within 1,000 kilometers of the comet and is
maneuvering to match velocity. The space probe took an amazing photo.
(Ugliest looking comet that I have ever seen!)
The space probe will send a lander to the comet's surface. (Next year,
maybe?)
Unfortunately, the European Space Agency is not as open with their data
as the American space agency is. They let their people study the photos
first before they release them to the public.
