Finland signs Artemis Accords – SpaceNews

WASHINGTON — Finland signed the Artemis Accords Jan. 21, the first country to do so this year amid questions about the future of the agreement in the new Trump administration.NASA said in a statement that Finland signed the Accords, which outline best practices for safe and sustainable space exploration, during the Winter Satellite Workshop 2025 at Aalto University in Espoo, Finland. The country is the 53rd to sign the Accords and the first to do so in 2025.“Today, Finland is joining a community of nations that want to share scientific data freely, operate safely and preserve the space environment for the Artemis Generation,” NASA Associate Administrator Jim Free said in the statement. “Forging strong partnerships between our nations and among the international community is critical...

Second SAR satellite advances Space42’s hybrid connectivity and imagery vision

TAMPA, Fla. — Emirati operator Space42 said Jan. 15 it has established communications with its recently launched Foresight-2 satellite, the second synthetic aperture radar (SAR) payload for the hybrid imaging and connectivity provider. Provided by Finnish SAR operator Iceye, Foresight-2 was one of 131 payloads SpaceX sent to sun-synchronous orbit Jan. 14 on a Falcon 9 rocket. Iceye also said it successfully made contact with three other SAR satellites on the Transporter-12 rideshare mission, which will join the Finnish operator’s constellation to provide services to government and commercial customers. All four satellites are designed to provide imagery with 25-centimeter resolution using radar signals, which are unaffected by cloud cover, weather, or lighting conditions. United...

NASA Jet Propulsion Laboratory evacuated due to LA wildfire

LOS ANGELES – Devastating fires here have forced the closure and evacuation of the NASA Jet Propulsion Laboratory as flames came less than one mile away from the facility. JPL, which operates robotic spacecraft and the Deep Space Network used for planetary missions, is located in a mandatory evacuation zone but officials have not reported any damage from the fire thus far. JPL director Laurie Leshin posted on X Jan. 8 that the facility had been damaged by the strong winds. “JPL is closed except for emergency personnel,” she wrote. “No fire damage so far (some wind damage) but it is very close to the lab. Hundreds of JPLers have been evacuated from their homes & many have lost homes. Special thx to our emergency crews. Pls keep us in your thoughts & stay safe.” JPL last...

The Engineering Behind Holiday Light Displays

Holiday light displays like Galaxy Lights might feel magical, but the creation of these incredible pieces of festive art are actually based in science and engineering! As someone with a mechanical engineering degree myself, I couldn’t resist diving into the tech behind the lights. LED Lights Thousands of carefully planned feet of wires and cables, and approximately 3 million lights make up the Galaxy Lights exhibits. The 200-foot LED light tunnel alone is made of more than 250,000 lights! Many exhibits like this are able to be created thanks to electrical engineers and designers working with light-emitting diode (LED) lights. These lights use much less electricity and release substantially less heat than more traditional incandescent holiday lights. The quick descri...

FCC allocates additional spectrum for commercial launches

WASHINGTON — The Federal Communications Commission has formally allocated additional spectrum for launch applications, fulfilling a provision in a bill passed earlier this year. The FCC published Dec. 31 a report and order that allocated spectrum between 2360 and 2395 megahertz for use in communications to and from commercial launch and reentry vehicles on a secondary basis. That band currently has a primary use for aircraft and missile testing communications. The order satisfies language in the Launch Communications Act (LCA) of 2024, signed into law by President Biden Sept. 26 after Senate passage by unanimous consent and House passage on a voice vote. The act directed the FCC to make available three bands for use in commercial launches and reentries, finalizing such allocations...
