Swiss Parachutist Becomes First to Jump From Solar Powered Plane

VOA News
25 August 2020

A parachutist completed the world’s first jump from a
solar-powered aircraft Tuesday, leaping from a height of 1,520
meters over western Switzerland.

The parachutist, Raphael Domjan, also is the founder of the
SolarStratos project, the group behind the feat, designed to
promote renewable energy. Domjan jumped from a two-seater
prototype plane after it reached a speed of 150 kilometers per
hour, and he landed near the project’s base in the city of
Payerne.

Domjan said there were many unknowns involved in the jump, such
as what would happen when he stepped out on the wing, where the
solar cells are mounted. He said he was not sure how the plane
would respond.

Domjan said part of the goal is to show renewable energy can be
used to pursue all kinds of activities – such as skydiving –
without producing planet-warming greenhouse gases.

The SolarStratos team follows the pioneering work of
Switzerland’s Solar Impulse mission, which completed the first
circumnavigation of the globe with a solar-powered plane in 2016.

The team’s goal is to eventually fly the single-propeller
aircraft studded with 22 square meters of solar panels into the
stratosphere. In 2022, the team hopes to carry out a
high-altitude flight powered exclusively by solar energy, seeking
to reach the stratosphere at an altitude of 20,000 meters.

Researchers Improve ‘Anti-Solar’ Energy Production

VOA News
24 August 2020

A new study suggests researchers have developed a method to
significantly improve “anti-solar” panels – a new clean,
sustainable way to generate energy at night.

Solar panels work because they are colder than the light given
off by the sun, so they can capture that heat and convert it into
electrical energy. “Anti-solar” panels work by being cooler than
heat radiated by the Earth at night, gathering that heat and
converting it into electricity using a thermoelectric generator.

Developers of the anti-solar panels say they can generate about a
quarter of the electricity as solar panels. But authors of a new
study published Monday in the journal Optics Express say they
have developed a method that, in simulations, has improved energy
generation in these anti-solar panels by as much as 120%.

The team of researchers from Stanford University and
Technion-Israel Institute of Technology said they achieved their
results by improving the thermoelectric generator. They used a
more efficient material to allow the generator to more
efficiently dump excess heat.

The researchers say that after they analyzed these upgrades,
their redesign of the anti-solar generator was able to produce
2.2 watts of energy per square meter – 120 times the energy
produced by previous anti-solar models.

The researchers are quick to point out there is a difference
between simulations and an actual physical system. But they also
say their design uses technology and materials that are currently
available. Their design works well enough to, theoretically,
convert heat for energy from other sources, such as running cars,
and could be used during the day.

They suggest this design might fill the gaps from other
sustainable sources and provide reliable energy in remote and
underdeveloped areas.

New ground station brings laser communications closer to reality

Matthew D. Peters
NASA’s Goddard Space Flight Center
21 August 2020

Optical communications, transmitting data using infrared lasers,
has the potential to help NASA return more data to Earth than
ever. The benefits of this technology to exploration and Earth
science missions are huge. In support of a mission to demonstrate
this technology, NASA recently completed installing its newest
optical ground station in Haleakala, Hawaii.

The state-of-the-art ground station, called Optical Ground
Station 2 (OGS-2), is the second of two optical ground stations
to be built that will collect data transmitted to Earth by NASA’s
Laser Communications Relay Demonstration (LCRD). Launching in
early 2021, this trailblazing mission will be the linchpin in
NASA’s first operational optical communications relay system.
While other NASA efforts have used optical communications, this
will be NASA’s first relay system using optical entirely, giving
NASA the opportunity to test this method of communications and
learn valuable lessons from its implementation. Relay satellites
create critical communications links between science and
exploration missions and Earth, enabling these missions to
transmit important data to scientists and mission managers back
home.

While optical communications provides missions with many
advantages, it can be disrupted by atmospheric interference such
as clouds. OGS-2 was chosen to be located in Hawaii because of
its clear skies, but bad weather can still happen. On a cloudy
day, LCRD would have to wait before transmitting data. In order
to avoid delays, services may be transferred to another ground
station developed by NASA’s Jet Propulsion Laboratory; OGS-1,
located in Table Mountain, California. To monitor cloud coverage
and determine if OGS-1 is needed, commercial partner Northrop
Grumman provided an atmospheric monitoring station that observes
weather conditions at the site. This monitoring station runs
nearly autonomously 24 hours a day, seven days a week.

LCRD and OGS-2 will demonstrate the numerous capabilities of
optical, or laser, communications for use as a communications
relay. Optical communications provides significant benefits for
missions, including data rate increases of 10 to 100 times more
than comparable radio frequency communications systems. This
increase means higher resolution data for missions, giving
scientists a much more detailed look at our planet and solar
system. Benefits also include decreased power needs, size and
weight, meaning longer battery life, more room for additional
instruments on spacecraft and potential cost savings at launch
due to lighter payloads.

“LCRD and its ground stations will demonstrate optical
communications as a relay, which means missions will be able to
transmit data from points in their orbit without direct line of
sight of the ground stations,” said Dave Israel, LCRD principal
investigator at NASA’s Goddard Space Flight Center in Greenbelt,
Maryland. “In 2013, NASA’s Lunar Laser Communication
Demonstration set a space communications bandwidth record from
the Moon using optical communications with a system requiring
direct line of sight.”

NASA’s Space Network manages OGS-2’s integration, test and
operations and will eventually operate LCRD. The Space Network
oversees a constellation of NASA communications satellites, known
as Tracking and Data Relay Satellites, and their associated
ground stations, which includes the White Sands Complex in White
Sands, New Mexico. The network provides continuous communications
services to missions in low-Earth orbit through radio frequency.
While radio frequency will continue to have utility in space
communications well into the future, the growing communications
needs of many missions necessitates greater data rates.

OGS-2’s installation was a collaborative effort between
government, commercial and academic institutions. The
Massachusetts Institute of Technology’s Lincoln Laboratory
provided the test and diagnostics terminal, which consists of
three parts: an optical subsystem, digital subsystem and
controller electronics. The three components send, receive and
process optical signals to and from LCRD.

Optical communications, through the development of LCRD and its
two ground terminals, could have far-reaching impacts for future
knowledge of Earth and our solar system. Spacecraft equipped with
optical communications systems will effectively allow enhanced
data, such as high-resolution video, to be brought back down to
Earth faster, thanks to increased data rates. With this data,
scientists will get a closer look at our universe with the
potential to uncover exciting new discoveries.

SWRadiogram.net Decoding #161!!

From time to time SWRadiogram likes to demonstrate that they can transmit text in non-Latin alphabets. This weekend they are broadcasting some Chinese text from Deutsche Welle. It’s about German passenger trains improving their on-time performance during the COVID-19 crisis. For the Chinese characters to display correctly, you need the UTF-8 character set. UTF-8 is default in Fldigi (at least during the past few years) and TIVAR, so most of you will not have any problems. If you see black rectangles instead of Chinese characters in the Fldigi receive pane, copy those rectangles to a word processor, and most likely the Chinese text will appear there.

Below are my picture decodes of this week’s radiogram. Enjoy!
