Amateur Radio Volunteers Active in Latest Round of California Wildfires

The massive and barely contained Thomas Fire in Southern California has consumed more than 230,500 acres, and the emergency has caused residents in fire-threatened areas to evacuate. Amateur Radio volunteers remain active supporting communication for American Red Cross shelters in Ventura County. More evacuations are likely, although the need for Amateur Radio assistance remains dynamic. Cal Fire said today (December 11) that evacuation operations will occur ahead of westward fire growth, speeded by low humidity and gusty Santa Ana winds, which will push the fire further into Santa Barbara, County. One of several fires that have broken out across Southern California, the Thomas Fire is far and away the largest.

The Northern Lights and other auroras are disappearing from some parts of Earth — but scientists predict a big comeback

First, the bad news for stargazers: Auroras are going dark in many parts of the world.

The number of these atmospheric light shows won’t bottom out for several years, which means locations far from Earth’s poles — such as the UK and northern continental US — may rarely if ever see the Northern Lights during that time. A study published earlier this year hints this dearth of auroras may last for decades.

But there’s plenty of good news.

Voyager 1 spacecraft thrusters fired up for first time since 1980

By Alaa Elassar and Ralph Ellis, CNN

(CNN)It’s a good idea to have a backup plan, especially in interstellar space.

NASA scientists needed to reorient the 40-year-old Voyager 1 — the space agency’s farthest spacecraft — so its antenna would point toward Earth, 13 billion miles away. But the “attitude control thrusters,” the first option to make the spacecraft turn in space, have been wearing out.

Amateur Radio-Carrying D-Star One CubeSat among Spacecraft Apparently Lost

The first Amateur Radio satellite to employ the D-Star digital voice and data format — D-Star One — was among about 20 secondary payloads lost on November 28 after an otherwise nominal launch of a three-stage Soyuz 2.1 booster from the new Vostochny Cosmodrome in the far reaches of eastern Russia. The mission carried the Russian Meteor M2-1 satellite — the primary payload — as well as a Canadian Telestar experimental satellite, and 17 other secondary payloads, including D-Star One. According to reports, a fault occurred in the sophisticated and autonomous Fregat upper stage, which, after separating from the launch vehicle, inserts multiple spacecraft into their respective orbits. A so-called “space tug,” Fregat has been in service for nearly 2 decades and has suffered three previous failures. Russian space agency Roscosmos is investigating the Fregat failure.
