“Rusty” Moon?

The blue areas in this composite image from the Moon Mineralogy Mapper (M3) aboard the Indian Space Research Organization’s Chandrayaan-1 orbiter show water concentrated at the Moon’s poles. Homing in on the spectra of rocks there, researcher found signs of hematite, a form of rust. Credit: ISRO/NASA/JPL-Caltech/Brown University/USGS Rust never sleeps. The moon is ‘rusting’ […]

So:  What About Really Large EVs?

Intro Who says lightning never strikes twice? Last week, I wrote an article regarding the difficulty of charging a hypothetical all-electric US vehicle fleet with today’s electric grid. But as before, part of a comment to that article made by longtime TAH reader rgr769 caught my eye – and made me wonder: . . . […]

Air Force moves forward with study to make next Air Force One supersonic

Startup Exosonic, which has been conducting experiments and studies to design a supersonic passenger aircraft that does not produce the noxious boom. Currently the US and most other countries prohibit non-military supersonic flight over land because the boom created by the airplane’s shockwave is a nuisance at best on the ground and at worst knocks […]

So:  If All US Vehicles Were Electric . . . Could We Charge Them?

Intro Last week, I wrote an article debunking the EPA’s blatantly misleading “108 MPG equivalent highway” claim for a particular electric vehicle, the 2020 Chevy Bolt. But part of a comment to that article made by longtime TAH reader rgr769 caught my eye – and made me wonder: . . . . If everyone in […]

Meet the Air Force’s “flying car”

This is not a joke. This the the brainchild of the Agility Prime program, a non-traditional program seeking to accelerate the commercial market for advanced air mobility vehicles. That thing that looks like it was cobbled together came from Air Force grant money though AFWERX. I expect this weird stuff from DARPA, but not the […]

So, Really:  Just How Much Fuel Do Electric Vehicles “Burn”?

Intro I keep hearing how great electric vehicles are. “They’ll save the planet!” proponents say. “They’re the wave of the future!” And I think we’ve all seen or heard the “equivalent of 100+ MPG” claims made by some electric vehicle manufacturers (and the EPA). But I haven’t seen one simple question answered: just how much […]

Small asteroid becomes closest ever seen passing Earth: NASA

This NASA/JPL/ZTF/Caltech Optical Observatories handout image obtained on August 18, 2020 shows asteroid 2020 QG (the circled streak in the center), which came closer to Earth than any other nonimpacting asteroid on record While I’m told size matters, “nonimpacting” is the key term here. Don’t really care about gross tonnage as long as they keep […]

The DARPA program will consist of three days of trials and tests for their artificial intelligence systems. The USAF Weapons School-trained F-16 pilot will face off against eight AI teams’ systems to […]
