NEW: The Pentagon has granted the Department of Homeland Security permission to test a heat ray weapon at the southern border. The military-grade heat ray can shoot an invisible beam of electromagnetic waves at potential intruders. The weapon can reach people more than half a mile away, according to the United States military. According to the Pentagon, the heat ray weapon is non-lethal but causes a burning sensation on the skin that can last between 10 and 15 minutes. The weapon sends an uncomfortable tingling effect on a potential intruder, generating "an instinctive and irresistible urge to run from the effect." Officials say the feeling is similar to the blast of heat you receive when you open up a hot oven.

In May, five Russian satellites surrounded a commercial imaging satellite. And this week, one of them — Cosmos 2612 — is maneuvering to get even closer. It will make its closest pass over the next 24 hours. (h/t @AdamCohen8 for the visualization)
This is wild... Russia seems to be threatening a *commercial* satellite that provides imaging services to Ukraine: ▸ starting about two weeks ago, Russia started maneuvering five (!) of their classified satellites to the same orbital inclination as the ICEYE satellite ▸ these burns were big, on the order of 100 m/s, clearly using chemical propulsion given the speed of the burns — very expensive and deliberate maneuvers ▸ as of last Friday, all five Russian satellites are now co-planar, at ~97.8° inclination, with three of ICEYE's satellites, and aligned in other orbital elements (e.g. RAAN) that make it clear they're specifically targeting this set ▸ I am a little skeptical that Russia is specifically targeting -X36 — there are two other satellites at the same inclination/RAAN (-X37 and -X38) — but the Russian sats are now all within striking distance of -X36, which is why people are concerned about it specifically; the closest cross-track distance is an estimated 500 meters (!!), all while the satellites are orbit 550 kilometers above Earth ▸ Russia has unleashed a cyberattack on a commercial satellite before (Viasat), and it is official Russian policy that commercially-owned infrastructure that aids in military efforts "may be legitimate target[s] for a retaliatory strike.” ▸ there's speculation that this could be a precursor to an RPO mission (meaning: physically grabbing the satellite or some other kind of non-kinetic attack like blinding/jamming) Worth tracking closely. And unfortunately more evidence that space is militarizing, fast.

1/x According to current orbital elements, the Russian #KOSMOS 2612 satellite is now within 1-2 km of #ICEYE-X36. Based on current elements, it might come within meters of the latter within a few hours from now. This is an #RPO without consent. (cont.)

A photographer captured a sunset framed within a buck’s antlers in the Kamloops grasslands, British Columbia, on July 22, 2024. Such a shot is said to occur only three times in a hundred years. 📸: Amanda Iceton

Well that didn’t take long! Starlink today announced it purchased 14 MHz in the 800 MHz band from Grain Management. No pricetag on that transaction, but Dish was supposed to buy that spectrum from T-Mobile for around $3.6 billion a few years ago. MORE: linkedin.com/posts/mikedano_…

This is a difficult story for us to share. But a beloved friend to many and our colleague, John Bisset, has died, after a period of illness. He was 73. He authored more than 900 Workbench columns for Radio World. radio-world.visitlink.me/B4G…

water is transparent only within a very narrow band of the electromagnetic spectrum, so living organisms evolved sensitivity to that band, and that's what we now call "visible light".
