From orbiting lasers to metal rods that strike from the heavens, the potential to wage war from space raises startling possibilities and serious problems

Light Saber: Space-based lasers would destroy targets by heating them with a powerful beam generated by a chemical reaction between hydrogen and fluorine. However, many such lasers would be required for global coverage; clouds and smoke block the beam; and keeping the beam on target long enough to cause damage is difficult.

12 June 2018—The world awakens to an international crisis: officials at the Tokyo airport have detained a foreign airliner suspected of carrying illegal arms. The aggressive and threatening response from the plane’s country of origin, a “rogue” state believed to possess both nuclear and biological weapons, adds credibility to the suspicion. Hamstrung by its rogue status, the country’s economy has been in free fall for decades, and with this latest incident, it’s widely feared that the country will launch a nuclear attack against Japan. U.S. satellites report escalating activity at the country’s rocket-launch facility; other U.S. intelligence indicates that three intermediate-range missiles are being fueled and are within a 15-minute launch window. No air-, sea-, or land-based military system is available to respond in time. The U.S. president demands that the country cease and desist immediately but receives no response. Five minutes later, the U.S. Strategic Command activates a heretofore undisclosed space-based laser; within minutes, it incinerates the launch facility’s command and control center, thus narrowly averting a catastrophe.

Today, such a scenario is science fiction, but it—or something like it—could become reality within the next decade or two. The irony is that the economic and political price the United States would have to pay to bring about such a system, even if it could be done, might well outweigh its military benefit.

The EV Transition Explained: Can the Grid Cope?

Palo Alto offers a glimpse at the challenges municipalities and utilities face

There have been vigorous debates pro and con in the US and elsewhere over whether the electric grids can support EVs at scale. The answer is a nuanced “perhaps.” It depends on several factors, including the speed of grid component modernization, the volume of EV sales, where they occur and when, what kinds of EV charging are being done and when, regulator and political decisions, and critically, economics.

The city of Palo Alto, California is a microcosm of many of the issues involved. Palo Alto boasts the highest adoption rate of EVs in the US: In 2020, one in six of the town’s 25,000 households owned an EV. Of the 52,000 registered vehicles in the city, 4,500 are EVs, and on workdays, commuters drive another 3,000 to 5,000 EVs enter the city. Residents can access about 1000 charging ports spread among over 277 public charging stations, with another 3,500 or so charging ports located at residences.

Janet Barth spent most of her career at the Goddard Space Flight Center, in Greenbelt, Md.—which put her in the middle of some of NASA’s most exciting projects of the past 40 years.

She joined the center as a co-op student and retired in 2014 as chief of its electrical engineering division. She had a hand in Hubble Space Telescope servicing missions, launching the Lunar Reconnaissance Orbiter and the Magnetospheric Multiscale mission, and developing the James Webb Space Telescope.
