Japan’s space agency wants to keep the satellite’s cameras out of military hands.

An unusual geopolitical situation is brewing aboard the International Space Station. Prior to the military coup in Myanmar earlier this year, Japan’s space agency JAXA had been collaborating with the country to build microsatellites that it planned to deploy in partnership with Myanmar’s government.

Now, JAXA has no idea what to do with the pair of 50-kilogram satellites, according to SlashGear. And while Japanese scientists hope to bring the agriculture and fishery-monitoring satellites to life, they’re currently holding them on the ISS instead of deploying them out of fear they might be misused for military purposes — a striking example of real-world geopolitics spilling over into space.

After the military coup in Myanmar, Teppei Kasai, the Asia program director for the group Human Rights Watch noted that it would be relatively straightforward to use the satellites’ Earth-facing cameras for military or surveillance purposes, according to SlashGear.

WASHINGTON — Stefanie Tompkins on March 15 assumed the top post at the Defense Advanced Research Projects Agency.

Tompkins is DARPA’s 23rd director.

She is a former military intelligence officer in the U.S. Army and previously worked at DARPA for nearly a decade. From 2007 until 2017 Tompkins served as program manager and deputy director of the agency’s Strategic Technology Office, DARPA chief of staff, as director of the Defense Sciences Office and as the acting deputy director of the agency.

Circa 2010

About 48 kilometers off the eastern coast of the United States, scientists from Rutgers, the State University of New Jersey, peered over the side of a small research vessel, the Arabella. They had just launched RU27, a 2-meter-long oceanographic probe shaped like a torpedo with wings. Although it sported a bright yellow paint job for good visibility, it was unclear whether anyone would ever see this underwater robot again. Its mission, simply put, was to cross the Atlantic before its batteries gave out.

Unlike other underwater drones, RU27 and its kin are able to travel without the aid of a propeller. Instead, they move up and down through the top 100 to 200 meters of seawater by adjusting their buoyancy while gliding forward using their swept-back wings. With this strategy, they can go a remarkably long way on a remarkably small amount of energy.

When submerged and thus out of radio contact, RU27 steered itself with the aid of sensors that registered depth, heading, and angle from the horizontal. From those inputs, it could dead reckon about where it had glided since its last GPS navigational fix: Every 8 hours the probe broke the surface and briefly stuck its tail in the air, which exposed its GPS antenna as well as the antenna of an Iridium satellite modem. This allowed the vehicle to contact its operators, who were located in New Brunswick, N.J., in the Rutgers Coastal Ocean Observation Lab, or COOL Room.

TOWARDS a METAMATERIALLY-BASED ANALOGUE SENSOR FOR TELESCOPE EYEPIECES jeremy batterson.

(NB: Those familiar with photography or telescopy can skip over the “elements of a system,” since they will already know this.)

In many telescopic applications, what is desired is not a more magnified image, but a brighter image. Some astronomical objects, such as the Andromeda galaxy or famous nebulae like M42 are very large in apparent size, but very faint. If the human eye could see the Andromeda galaxy, it would appear four times wider than the Moon. The great Orion nebula M42 is twice the apparent diameter of the Moon.

Astrophotographers have an advantage over visual astronomers in that their digital sensors can be wider than the human pupil, and thus can accommodate larger exit pupils for brighter images.

Have you ever heard of “Allostatic Load” and “Operator Syndrome?”

I stumbled across the work of Christopher Frueh while doing some research on physiological, psychological and hormonal stress mitigation. Frueh, along with his team of researchers, psychologists and former SOF operators, has been exploring the human mind, defining PTSD and outlining Special Operator’s Syndrome. This is one of the only programs in the country specifically designed to help those suffering from this condition.

“Allostatic load” is the cost on your body of chronic stress and physical demands of a career with the military special forces, according to Science Direct. The military recipe for “burning the candle at both ends” includes high intensity physical fitness training, the high stress of operations and being away from home, the trauma of witnessing death, war or injury. Add in the inability to sleep or eat well, and the operator limits the two main recovery responses, which leads to chronic stress. This adds up to Allostatic Overload.

The Air Force Research Laboratory awarded SpaceX an $8.5 million contract to investigate manufacturing techniques for heat shields that protect hypersonic vehicles in flight.

WASHINGTON — The Air Force Research Laboratory awarded SpaceX an $8.5 million contract to investigate advanced materials and manufacturing techniques for heat shields that protect hypersonic vehicles in flight.

Heat protection is a critical technology to shield hypersonic vehicles from the intense heat experienced when flying at more than five times the speed of sound.

The Defense Department is hungry for small drones that will track objects and fly into buildings, combat zones and other dangerous areas with little help from remote pilots. Self-piloting drones will become a key part of fighting and other military activities in the years to come, said Mike Brown, director of the Defense Innovation Unit, a Pentagon organization that aims to facilitate cooperation between the military and the tech industry.

While much has been made of tech’s unwillingness to work with the Pentagon, start-ups are still plumbing the industry’s decades-long ties to the military.
