AMSAT-DL Submits Lunar Lander Proposal to European Space Agency

13 July 2020

Germany's amateur satellite organization AMSAT-DL has submitted a
comprehensive proposal to the European Space Agency (ESA) for its
Lunar Amateur Radio Transponder (LunART) lunar lander - a
communications platform on the Large European Lander to support
communication and payload experiments. AMSAT-DL's Peter Gülzow,
DB2OS, and Matthias Bopp, DD1US, say that a LunART (called
"LunaART" in the AMSAT-DL proposal) would support direct
communication with Earth via amateur radio, support university
and student payloads and offer direct access to their
experiments, and expand the reach of radio science. It could also
provide backup communication capability and capacity during an
emergency, or when the ESA network is busy.

The comprehensive radio platform would use the European frequency
protocol of 2.4 GHz up and 10.45 GHz down (approximately 100 W),
pioneered in the QO-100 satellite, the first geosynchronous
amateur radio payload. The platform would also include a VHF/UHF
transponder. AMSAT-DL would develop and build the necessary
hardware and software and provide ground station support via the
20-meter dish at AMSAT-DL headquarters in Bochum, Germany. They
envision developing a smaller ground station with an
approximately 1-meter dish to support groups, including schools
and universities. Low-power beacons would transmit on various
frequencies from VHF (145 MHz) through SHF (up to 24 GHz or even
47 GHz), AMSAT-DL's proposal says.

"This transponder would also be an ideal platform to develop new
transmission schemes with novel modulation and coding techniques
optimized for long-distance communications with the corresponding
high latency (long delays)," AMSAT-DL said. "This would provide
essential knowledge in preparation of a future Mars mission." In
addition, LunART could include the capability to transmit still
or slow-scan television images and video to schools "from cameras
attached to the lander monitoring the moon surface and perhaps
the Earth in the background [which] would be ideal stimuli for
getting school kids and STEM organizations further interested in
space."

The proposal is on open access at the ESA website and is now
being evaluated. AMSAT-DL's LunART follows the Lunar Amateur
Radio Interaction Experiment (LARIE) proposal from Andy Thomas,
G0SFJ. Both refer to weak signal modes and suggest the same
frequency bands. Thomas said he welcomes LunART as a
well-developed proposal and hopes ESA will support it as well.

Solar flow battery efficiently stores renewable energy in liquid
form

Michael Irving
14 July 2020

Capturing energy from the Sun with solar panels is only half the
story – that energy needs to be stored somewhere for later use.
In the case of flow batteries, storage is relegated to vats of
liquid. Now, an international team led by University of
Wisconsin-Madison scientists has created a new version of these
solar flow batteries that's efficient and long-lasting.

To make the new device, the team combined several existing
technologies. It's a silicon/perovskite tandem solar cell, paired
with a redox flow battery, which the team says will allow people
to harvest and store renewable energy in one device. Not only is
it efficient, but it should be inexpensive and simple enough to
scale up for home use.

The energy-harvesting part of the equation combines the long-time
industry-leading material – silicon – with a promising young
upstart called perovskite. These tandem solar cells have proved
better than either material alone, since the two materials
capture different wavelengths of light.

For storage, the team turned to a flow battery. Traditionally,
these devices contain two liquids, housed in separate tanks, that
function as the electrolytes. Electricity from the solar cell
charges one of the liquids, where it can sit more or less
indefinitely. When the power is needed, the two liquids interact
in a middle chamber, creating a chemical reaction that produces
electricity.

The team used a theoretical modeling method to determine which
chemicals would operate at the ideal voltage, to maximize
efficiency. They settled on two organic compounds dissolved in
saltwater, and tests with the final physical device confirmed
that it was a good match.

The team recorded 20 percent efficiency, which is up there with
the best. The device was able to maintain a high efficiency, and
most of its capacity, over hundreds of hours and charge-discharge
cycles. That gives it a much longer life than other flow
batteries, whose acidic electrolytes tend to corrode the tanks.

"That's 20 percent efficiency any time you like," says Song Jin,
lead researcher on the study. "You can use the solar electricity
right away during the day and get 20 percent, or you can use it
in the evening from storage and get 20 percent."

The team plans to continue developing the solar flow batteries to
improve efficiency, reduce costs and investigate ways to scale
them up for practical large-scale use.

The research was published in the journal Nature Materials.
