Wireless Power Transmission using 10 GHz

May 13, 2022

Paul Jaffe KJ4IKI and team at U.S. Naval Research Laboratory have
succeeded in transferring 1.6 kw of power over a 1 km path using
10 GHz

The US Navy describes it as being "the most significant power
beaming demonstration in nearly 50 years."

The aim was to demonstrate power beaming of 1 kW of electrical
power over a distance of 1 km using 10 GHz. The two sites used
were the U.S. Army Research Field at Blossom Point in Maryland,
and The Haystack Ultrawideband Satellite Imaging Radar (HUSIR)
transmitter at the Massachusetts Institute of Technology (MIT).

"The reason for setting those targets is to push this technology
farther than has been demonstrated before," said Paul Jaffe
Ph.D., Power Beaming and Space Solar Lead. "You don't want to use
too high a frequency as it can start losing power to the
atmosphere," Rodenbeck said. "10 GHz is a great choice because
the component technology out there is cheap and mature. Even in
heavy rainfall, loss of power is less than five percent."

In Maryland, the team exceeded their target by 60 percent by
beaming 1.6 kW just over 1 km. At the Massachusetts site, the
team did not have the same peak power, but the average power was
much higher thereby delivering more energy. Jaffe said these
demonstrations pave the way for power beaming on Earth, in space,
and from space to Earth using power densities within safety
limits set by international standards bodies.

"As engineers, we develop systems that will not exceed those
safety limits," Jaffe said. "That means it's safe for birds,
animals, and people."

A CubeSat is flying to the moon to make sure Lunar Gateway's
orbit is stable

by Matt Williams
Universe Today
May 16, 2022

Before this decade is over, NASA will send astronauts to the moon
for the first time since the Apollo Era. As part of the Artemis
Program, NASA also plans to establish the infrastructure that
will allow for a "sustained program of lunar exploration." A key
part of this is the Lunar Gateway, an orbiting space station that
will facilitate regular trips to and from the lunar surface. In
addition to being a docking point for ships going to and from
Earth, the station will also allow for long-duration missions to
Mars.

The Gateway will have what is known in orbital mechanics as a
"near rectilinear halo orbit" (NRHO), meaning it will orbit the
moon from pole to pole. To test the long-term stability of this
orbit, NASA will be sending the Cislunar Autonomous Positioning
System Technology Operations and Navigation Experiment (CAPSTONE)
to the moon by the end of May. This nine-month CubeSat mission
will be the first spacecraft to test this orbit and demonstrate
its benefits for the Gateway.

The CAPSTONE, a 12-unit CubeSat owned and operated by Advanced
Space in Westminster, Colorado, is a technology demonstrator that
will test the stability of a halo orbit and several crucial
systems. The mission is scheduled to launch on May 31st (at the
earliest), when a Rocket Lab Photon spacecraft bus will launch
the CAPSTONE on its four-month journey to the moon. After a
series of "clean-up" maneuvers that will insert the spacecraft
into its orbit, the CAPSTONE will spend at least six months
around the moon, firing its thrusters only occasionally to
maintain its orbit.

This elliptical orbit will take CAPSTONE on a path that leads
from one lunar pole to the other, tracing a constant oval pattern
around the moon. It will take nearly a week to complete and will
see the CubeSat traveling slowest when it is around the South
Pole, where it will be at its farthest distance from the surface
(76,000 km, 47,000 mi). When it reaches above the North Pole, the
spacecraft will reach its peak velocity and make its closest pass
to the surface at 3,400 km (2,100 mi).

Elwood Agasid, a deputy program manager of Small Spacecraft
Technology at NASA's Ames Research Center, explained in a NASA
press release: "CAPSTONE will be precisely controlled and
maintained and will benefit tremendously from the nearly-stable
physics of its near rectilinear halo orbit. The burns will be
timed to give the spacecraft an extra boost as it naturally
builds momentum - this requires a lot less fuel than a more
circular orbit would require.

"This orbit has an added bonus of allowing Gateway to have
optimal communications with future Artemis missions operating on
the lunar surface as well as back to Earth. This could unlock new
opportunities for future lunar science and exploration efforts."

These tests will validate the power and propulsion requirements
for maintaining its orbit as predicted by NASA's models, reducing
logistical uncertainties. During its many orbits, the CAPSTONE
will demonstrate the reliability of an innovative
spacecraft-to-spacecraft navigation system. This system will
measure the position of the CAPSTONE CubeSat relative to NASA's
Lunar Reconnaissance Orbiter (LRO) - which has been in orbit of the
moon since 2009 - without relying on ground stations.

To test this system, CAPSTONE will carry a second dedicated
payload flight computer and radio, which will perform
calculations to determine where the CubeSat is in its orbital
path. The data obtained from this crosslink with the LRO will be
used to measure how far apart the two satellites are and how
quickly this distance changes. This peer-to-peer information
sharing will allow mission controllers to evaluate CAPSTONE's
autonomous navigation software and determine the CubeSat's
position in real-time.

By validating this software, known as the Cislunar Autonomous
Positioning System (CAPS), future NASA missions (as well as
agency and commercial partners) will be able to determine the
location of their spacecraft without relying on Earth-based
tracking systems. This comes with the added benefit of freeing up
bandwidth for ground-based antennas, allowing mission controllers
to mission science data transmissions over the relatively routine
tracking process.

NASA engineers also expect that the NRHO will allow them to
station much larger spacecraft in orbit around the moon for about
15 years. This includes the Gateway itself and the spacecraft
that will dock with it to refuel or conduct the next leg of their
journey - i.e., the Orion spacecraft and the Deep Space Transport
(DST). This is crucial to NASA's "moon to Mars" mission
architecture, which will involve sending crewed missions to the
Red Planet in the early 2030s.
