Outer space is already an essential part of America’s ability to fight wars. Our military depends on satellites for many things, such as communications, reconnaissance and targeting information. See more in Season 4, Episode 8, “Space Wars.”

And now, for old fashion Nuclear Doom.

Music in comments.

UNITED NATIONS (AP) — The United Nations chief warned Monday that “humanity is just one misunderstanding, one miscalculation away from nuclear annihilation,” citing the war in Ukraine, nuclear threats in Asia and the Middle East and many other factors.

Secretary-General Antonio Guterres gave the dire warning at the opening of the long-delayed high-level meeting to review the landmark 50-year-old treaty aimed at preventing the spread of nuclear weapons and eventually achieving a nuclear-free world.

The danger of increasing nuclear threats and a nuclear catastrophe was also raised by the United States, Japan, Germany, the U.N. nuclear chief and many other opening speakers at the meeting to review progress and agree to future steps to implement the Nuclear Nonproliferation Treaty, known as the NPT.

The U.S. Space Command’s proposed move to Huntsville passed a big test July 13 when the Pentagon released a draft environmental assessment finding “no significant impacts on the human or natural environment” if the headquarters is built on the Redstone Arsenal site.

Although there remain four steps ahead of the move, Republican U.S. Sen. Tommy Tuberville of Alabama said the environmental assessment should be the last major hurdle for the plan to move the command from startup headquarters in Colorado to a permanent site. The move would bring 1,800 headquarters staff and their families to north Alabama.

“The Redstone Arsenal site is the (Department of the Air Force’s) Preferred Alternative for implementation of the Proposed Action,” the environmental assessment said. The proposed action is a permanent headquarters.

Almost 75 years ago, U.S. Air Force pilot Chuck Yeager became the first person to fly faster than the speed of sound. Engineers have been pushing the boundaries of ultrafast flight ever since, attaining speeds most of us can only imagine.

Today, military fighter jets like the F-15 routinely surpass Mach 2, which is shorthand for twice the speed of sound. That’s supersonic level. On a hypersonic flight—Mach 5 and beyond—an aircraft travels faster than 3,000 miles per hour. At that rate, you could make it from New York to Los Angeles on a lunch break.

The same propulsion technology that goes into rockets has made hypersonic speeds possible since the 1950s. But to make hypersonic flight more common and far less expensive than a , engineers and scientists are working on advanced jet engine designs. These new concepts represent an enormous opportunity for , space exploration and national defense: Hypersonic aircraft could serve as reusable launch vehicles for spacecraft, for example.

DARPA, in partnership with the U.S. Air Force, completed a free flight test of its Hypersonic Air-breathing Weapon Concept (HAWC) last week. The missile, built by Raytheon Technologies, was released from an aircraft seconds before its Northrop Grumman scramjet (supersonic combustion ramjet) engine kicked on. The engine compressed incoming air mixed with its hydrocarbon fuel and began igniting that fast-moving airflow mixture, propelling the cruiser at a speed greater than Mach 5 (five times the speed of sound).

The HAWC vehicle operates best in oxygen-rich atmosphere, where speed and maneuverability make it difficult to detect in a timely way. It could strike targets much more quickly than subsonic missiles and has significant kinetic energy even without high explosives.

“The HAWC free test was a successful demonstration of the capabilities that will make hypersonic cruise missiles a highly effective tool for our warfighters,” said Andrew “Tippy” Knoedler, HAWC program manager in DARPA’s Tactical Technology Office. “This brings us one step closer to transitioning HAWC to a program of record that offers next generation capability to the U.S military.”

WASHINGTON — The Defense Innovation Unit is funding space projects that the agency hopes will spur commercial investments in satellite refueling technologies and support services for geostationary satellites.

“Imagine a world where every 18 to 24 months, you could simply upgrade the processor on a satellite in GEO the way that you upgrade your smartphone to take advantage of new processing power and new functionality,” said Steve “Bucky” Butow, director of the space portfolio at the Defense Innovation Unit.

DIU, based in Silicon Valley, is a Defense Department agency established in 2015 to help bring privately funded innovation into military programs.
