Tiny probes could sail to outer planets with the help of
low-power lasers

by American Chemical Society
February 23, 2022

Space travel can be agonizingly slow: For example, the New
Horizons probe took almost 10 years to reach Pluto. Traveling to
Proxima Centauri b, the closest habitable planet to Earth, would
require thousands of years with even the biggest rockets. Now,
researchers calculate in ACS' Nano Letters that low-power lasers
on Earth could launch and maneuver small probes equipped with
silicon or boron nitride sails, propelling them to much faster
speeds than rocket engines.

Instead of catching wind, like the sails on boats, "laser sails"
would catch laser beams and could, in principle, push spacecraft
to nearly the speed of light. Scientists have been working on
this concept for a while. For example, one privately funded
project called the Breakthrough Starshot initiative aims to send
a small, sailed probe weighing about a gram to Proxima Centauri b
with a flight taking only 20 years. It would be propelled to 20%
of light speed by a 100 GW, kilometer-square laser array. Ho-Ting
Tung and Artur Davoyan wondered if much lower-power, smaller
laser arrays could find use in applications where conventional
electric and chemical rockets are now used. The lasers might
someday be able to adjust the orbit of satellites after launch or
propel tiny sailed probes on interplanetary or interstellar
missions, without requiring large amounts of fuel.

The researchers performed calculations to show that even lasers
with powers of about 100 kW and array sizes of about a meter
could power a 1-gram probe at velocities far exceeding the
current record, with only minutes to hours of laser illumination.
According to their calculations, the lasers could maneuver small
probes between different Earth orbits in only a day, which is not
possible with current electrical and chemical rockets. The team
determined that the best materials for the laser sails, which
allowed high reflectivity and rapid cooling, were silicon nitride
and boron nitride structured at the nanoscale. Finally, the
researchers calculated that these tiny laser-propelled probes
could travel fast enough to escape the solar system, reaching
five times higher velocities than the New Horizons probe. These
prototype sailed spacecraft, driven by low-power lasers, could
pave the wave for fast space exploration and future interstellar
flight, the researchers say.

From TechXplore:

New laser station lights the way to debris reduction

by European Space Agency
February 16, 2022

ESA's Izaña-1 laser ranging station in Tenerife, Spain, has
recently undergone months of testing and commissioning, passing
its final tests with flying colors. As it reached "station
acceptance," it was handed over to ESA from the German company
contracted to build it, DiGOS. The station is a technology
testbed and a vital first step in making debris mitigation widely
accessible to all space actors with a say in the future of our
space environment.

From satellite tracking to debris

Imagine lasers pointing from Earth into the skies, seeking out
satellites and bits of space trash and measuring their positions
and trajectories to prevent catastrophic collisions. You don't
have to try too hard—this is very nearly the day-to-day reality
at ESA's new Izaña 1 (IZN-1) laser ranging station in Tenerife,

IZN-1, developed and now operated by ESA, is a testbed for future
technologies and was installed in mid-2021 at the Teide
Observatory. The station, telescope and laser have undergone
months of testing and commissioning and since July last year have
aimed the green beam of concentrated light to the sky to actively
detect, track and observe active satellites.

At present, the laser operates at 150mW but it will soon be
upgraded so it can also track debris objects with a much more
powerful infrared laser with an average power of 50 Watts.

"Currently, only satellites fitted with retroreflectors can be
tracked from ESA's Izaña station, making up just a proportion of
the total population," explains Clemens Heese, Head of Optical

"The station will be upgraded in the next couple of years,
enabling it to perform the same vital ranging services with
uncooperative targets—vitally, debris objects and older
satellites without retroreflecting patches."

The first of many in Europe

While dozens of laser tracking stations are dotted around Europe,
the Izaña station's dual functionality makes it a first. Built by
German company DiGOS, the remotely controlled Izaña station can
also be used for optical communications and is intended to become
a state-of-the-art, fully autonomous robotic system. It is hoped
to be the first of many across the globe.

The technology, relatively new in the history of ground-based
observations of space debris, will mean the station can track
previously invisible defunct objects lurking above the blue
daytime skies.

As ESA's newest addition to the Space Safety family, Izana-1
provides support for vital collision avoidance and provides a
testbed for new sustainable technologies like laser momentum
transfer or coordination of space traffic.

Such satellite and debris tracking capability in Europe could
contribute to building and accessing a European catalog of space

Lasers in space. Is that … safe?

But hold on, there are birds, planes, astronauts above us!
Doesn't aiming lasers into the sky come with an unacceptable
risk? Fortunately, lasers used for satellite and debris tracking
would be a disappointment to any self-respecting Bond villain.

Ultimately, the IZN-1 station will use a power of under 100
Watts, giving the Izaña laser about 1/20th of the energy of an
electric kettle.

These pinpoint light sources shine short pulses of light at their
target, determining the distance, velocity and orbit of each one
with millimeter precision, calculated from the time it takes to
complete the return journey.

Although such lasers don't come anywhere close to cutting
through, or even nudging (yet) the objects they target, they can
damage sensitive optical instruments on satellites and the paths
of aircraft must be considered.

"If lasers strike planes they can be very dangerous, as pilots
can become distracted and in worst-case scenarios, lose control,"
explains Andrea di Mira, ESA Optoelectronics Engineer.

"We are very, very careful that this does not happen, with a set
of sensors scanning the sky for aircraft to ensure our lasers do
not get remotely close to them."

These lasers also have the potential to disrupt telescopes
studying the night's sky. To prevent this, the Laser Traffic
Control System (LTCS) was introduced by the Instituto de
Astrofísica de Canarias (IAC)—much like IZN-1 helps to prevent
collisions between objects in orbit, the LTCS software prevents
'collisions' between laser light and areas of observation.
Additionally, switching to an infrared laser frequency can
minimize conflicts with astronomers.

A vital step toward space traffic control

As the era of New Space is now fully underway, large
constellations are being launched to the skies consisting of
thousands, sometimes tens of thousands of satellites.

Current, costly methods of collision avoidance will be futile as
numbers increase and as such the international space community
will need to establish a method of space traffic control.

For this, precise and rapid determination of the location,
velocity and orbit of space objects will be vital, and ESA's
IZN-1 station will provide a much-needed testbed for this
technology, far more accurate than current radar methods, to be

Laser focus on the future

In the near future, ESA's IZN-1 station will be a fully
autonomous, highly productive satellite and debris tracking
station. It will also be used to test the concept of 'networked
space debris laser ranging' to build a satellite catalog.

When it comes to optical communication, it will also be upgraded
to receive signals with a very high data rate of 10 gigabits and
beyond (adhering to international standards) from satellites in
low-Earth orbit 400 km away.

Izaña will then become part of a planned European Optical Nucleus
Network, the first operational optical communication ground
station service of its kind that will be made available to the
wider commercial space community.

On top of all this, the station provides an opportunity to test
and develop technologies underpinning 'laser momentum transfer,"
in which lasers would not merely shine a light on debris objects
but very gently nudge them into new orbits, out of the way of
potential collisions and out of the busiest orbital highways.

As IZN-1 is welcomed into to ESA's Space Safety family, so is a
bright future of sustainable technologies, vital for a
responsible future in orbit and beyond.
