France Creates Space Command To Help Bid To Be Third Space Power
By Thierry Dubois
Luch Olymp, a Russian satellite, is French Armed Forces Minister Florence Parly's favorite enemy. Last year, she revealed it had, in 2017, moved into close proximity to Athena-Fidus—a Franco-Italian satellite used for military communications—and tried to intercept its signal. The French military have kept a close eye on Luch Olymp. “I can't resist telling you the latest—it left a business card to another eight satellites belonging to various countries,” she says.
The French government uses Luch Olymp as an example of the mounting threats against the country's space-based assets. A feeling of vulnerability was the basis for the government's decision, announced last year, to devise a space defense strategy. Now officially unveiled, it includes developing patrol satellites and space-based directed-energy weapons.
The move confirms the trend for nations to consider space as an additional theater of operations for future conflicts.
In the U.S., President Donald Trump signed off on a detailed plan on how to organize military space in February. The document, dubbed Space Policy Directive-4, proposes the creation of a sixth military service focused on space. The House and Senate are in agreement that a separate space service is necessary, but they are at odds on the details. Both chambers will enter conference this summer to hash out the specifics and are hopeful an agreement will be reached this fall.
Last year, a report on worldwide threats to Congress stated that Russian and Chinese anti-satellite (ASAT) weapons would probably become operational within the next few years. “Both countries also are advancing directed-energy weapons technologies for the purpose of fielding ASAT weapons that could blind or damage sensitive space-based optical sensors, such as those used for remote sensing or missile defense.”
Referring to China and the U.S., Parly says she believes in France asserting itself as the world's third space power.
A space command with an initial 220 personnel will be created Sept. 1. One of its roles will be to establish French space doctrine. The operations center of the space command is to open in 2024 in Toulouse, where it is expected to benefit from local synergies with the space industry.
As the space command will be part of the French Air Force, the latter is to become the Air and Space Force (Armee de l'Air et de l'Espace).
The space command to be integrated into the air force will replace the existing Joint Space Command, created in 2010. The Joint Space Command did help French forces with their space ambitions, says Parly. However, it is believed not to be effective because of a lack of unity in the command chain and the development of a military space policy, as well as geographically scattered sites.
“Space is a new front,” Parly says. She earlier requested the integration of cameras into the Syracuse 4A and 4B communications satellites, due to be launched in the early 2020s. The cameras will monitor the satellites' close environment.
Parly wants to see nanosatellites patrolling in orbit as soon as 2023. They will be used to detect threats and may also carry high-power lasers.
Such weapons, which may also be integrated into France's “valuable” satellites, will be able to “dazzle” a threatening spacecraft, says Parly. France is behind in high-power lasers, she admits, but she is confident the country's research laboratories and OEMs will catch up.
In fact, aerospace research center ONERA has already conducted a test that temporarily made inoperative the optical sensors of an Earth-observation satellite at the end of its life. According to a report by two members of the French National Assembly, ONERA could build a system that would make such sensors inoperative permanently. ONERA is also taking part in the TALOS project. Launched last year by the European Defense Agency to create high-power laser beam weapons, TALOS is led by CILAS, an ArianeGroup subsidiary.
Other ideas for “active defense” include repurposing systems currently developed under a European Space Agency program to remove debris from orbit, using a net or harpoon.
France's military programming law for 2019-25 already includes €3.6 billion ($4 billion) for the renewal of satellites—such as launching the CSO Earth-observation satellites. Parly announced another €700 million will be added over that period. They will be used, among other expenditures, to create demonstrators. “Full capacity” of the space command is expected in 2030.
On the ground, the existing Graves radar, which monitors low Earth orbit, will be upgraded in 2022. Parly has requested its successor deliver an initial operational capability in 2025, sooner than initially planned. Eventually, it will have to detect an object “the size of a shoe box” at 1,500 km (930 mi.).
Debris is a concern, as well as illegal launches such as that of Swarm Technologies' picosatellites last year.
The government is counting on European cooperation, especially with Germany and Italy, to make future surveillance equipment and weapons affordable.

Can a dragonfly teach a missile how to hunt?
By: Jen Judson WASHINGTON — A computational neuroscientist is studying whether a dragonfly's excellent hunting skills can be replicated in a missile's ability to maneuver and destroy targets midair with better precision. Dragonflies are vicious little creatures with a hit-to-kill track record of 95 percent, meaning only 5 percent of its prey escapes. Sandia National Laboratories' Frances Chance is building algorithms that simulate how a dragonfly processes information when intercepting prey, and she's testing them in a virtual environment. So far, the results are promising. The laboratories are federally funded and focus on national security missions through scientific and engineering research. The project is a yearlong, high-risk, high-gain effort that will wrap up in September, and it is funded by Sandia's Autonomy for Hypersonics Mission Campaign, Chance said. “I think what is really interesting about insects, in general, is they do something really fast and really well, but they are not particularly smart in the way you or I would think of ourselves as being smart,” Chance told Defense News in a recent interview. While insects may not be the right fit for studying cognitive capabilities to develop complex artificial intelligence, they are ideal for developing efficient computations for intercept capability. A dragonfly can react to a particular prey's maneuvers in 50 milliseconds, Chance explained. That amount of time accounts for information to cross three neurons in a dragonfly's brain. This indicates the dragonfly doesn't learn how to hunt, but rather the skill is inherent and part of its brain's hard-wiring. “The challenge then is: Is there anything that we can learn from how dragonflies do this that we can then bring to the next generation of missiles, or maybe even the next-next generation of missiles?” Chance said. By developing an artificial neural network that mimics a dragonfly's ability to hunt and then applying it to missile capabilities that rely on computation-heavy systems, one could reduce the size, weight and power needed for a missile's onboard computers; improve intercept techniques for targets such as hypersonic weapons; and home in on targets using simpler sensors. If the model of a dragonfly's neural circuit developed through Chance's research shows enough promise, she would then pass the information to scientists, who would try to directly apply it to weapons systems. One of the greatest leaps involves adapting an algorithm to handle the speed at which a missile flies. While a dragonfly is fast, it's not nearly as fast as a missile. Animal brains process information significantly slower than a computer, so it's possible computations can be sped up to better align with the speed at which a missile approaches targets. “The hope is that even if the algorithm isn't wildly successful, you might be able to say something about what you can get away with in terms of what types of capabilities you give the next generation of weapons,” Chance said. The model she's building is several steps removed from implementation onto a weapon. “I would consider the project complete when we have a viable model — ‘viable' meaning it does interception — and a bonus if it's neurobiologically plausible. There is no reason to force that for this type of research, but only because it doesn't necessarily matter; so something biologically inspired that works I would consider a success.” https://www.c4isrnet.com/land/2019/08/05/can-a-dragonfly-teach-a-missile-how-to-hunt/
