Japan’s military is testing Elon Musk’s Starlink for potential adoption

The technology may be acquired by the Ministry of Defense in the next fiscal year.

Reuters.

If all goes well, the organization may adopt the technology next fiscal year.

Reuters reported on Sunday that Japan’s military is testing Elon Musk’s Starlink satellite internet service according to the Yomiuri newspaper that cited unnamed government sources.

Japan’s Ministry of Defense already has access to communication satellites in geostationary orbit but lacks access to the devices in low Earth orbit which Starlink would provide, the Yomiuri said.

Omega-3 fatty acids linked to lower atrial fibrillation risk in U.S. veterans

A recent study published in The American Journal of Clinical Nutrition determined whether marine omega-3 fatty acid (FA) consumption increases atrial fibrillation (AF) risk among United States military veterans.

Living Inside SpaceX Starship Space Stations Versus Submarines

There is some debate on how many people could fit inside SpaceX Starships that are converted into Space Stations. We can get a better maximum estimate by looking at the Apollo mission and German and American submarines.

Apollo’s Command Module had a diameter of 12.8 feet (3.9 meters) and a height of 11.4 feet (3.47 meters). Total dry weight was 12,787 pounds (5,800 kg) and its crew cabin volume was 218 cubic feet (6.17 cubic meters). This held three astronauts for about one week. If one were to pack Astronauts with Apollo standards then 400 could fit into the 1,000 cubic meters of the SpaceX Starship. Tripling the space given for each Starship Astronaut would still leave room for 150.

Type VII U-boats were the most common type of German World War II U-boat. They were notorious for being cramped. They had about 800 cubic meters of volume and a lot of the space was for torpedos, fuel and engines. They could hold a crew of about 52.

Putin vows to deploy world’s most powerful nuke ‘Satan 2’ to ‘combat duty’

VLADIMIR Putin vowed to deploy his hypersonic “Satan-2” nuclear-capable missiles in a chilling new threat to the West.

The Russian leader said that the new generations of the Sarmat intercontinental ballistic missiles — thought to be the world’s most powerful — would soon be deployed for combat duty.

In a speech to newly graduated soldiers, Putin warned: “In the near future, the first launchers of the Sarmat complex with a new heavy missile will go on combat duty.”

First deployment outside Russia since fall of the USSR

Vladimir Putin confirmed Russia has sent nuclear arms to its ally Belarus, which borders Ukraine. Putin has repeatedly warned that Russia, which has more nuclear weapons than any other country, will use all means to defend itself. Russia has a huge numerical superiority over the united states and the nato military alliance when it comes to tactical nuclear weapons. The united states believe Russia has around 2,000 such working tactical warheads. Reports say, the united states has around 200 tactical nuclear weapons, half of which are at bases in Europe. Remember, Belarus has borders with 3 nato members — Poland, Lithuania & Latvia. The treaty on the non-proliferation of nuclear weapons, signed by the soviet union, says no nuclear power can transfer nuclear weapons or tech to a non-nuclear power.

JetZero’s Next-Gen Aircraft Could Change How We Fly for the First Time in Decades

A California-based startup called JetZero has a different idea: changing the shape of commercial planes and the material they’re made of. The company unveiled its designs for the midsize commercial and military tanker-transport markets this spring, and has big plans to upend the way air travel looks and feels—as well as how much it costs and how much carbon it emits. Tony Fadell, founder of venture capital firm Build Collective and a JetZero investor and strategic advisor, thinks the company could be the “SpaceX of aviation” due to its potential to disrupt the existing business model.

JetZero’s planes, which are still in the concept/prototype phase, have a blended wing body design. That means the wings merge with the main body of the aircraft, rather than being attached to a hollow tube like the planes we travel in today. Picture the body of a manta ray: wide and flat, it tapers off to a narrower fin at each side, with a head and a tail. A blended wing body aircraft isn’t terribly different, though on JetZero’s models the body isn’t quite as wide.

Besides providing a lot more space, this design is more aerodynamic than tube-and-wing planes. JetZero plans to fly its planes at higher altitudes than today’s norm (40 to 45,000 feet rather than 30 to 35,000), and says its airframe will cut fuel burn and emissions in half. It plans to make its planes out of carbon fiber and kevlar (a strong lightweight fiber used for things like body armor, bulletproof vests, car brakes, boats, and aircraft). The company says its planes’ lighter weight and improved aerodynamics would be able to fly at the same speed and range as existing midbody jetliners, but burn half as much fuel in the process.
