Top Stories Tamfitronics PARIS — After seeing the disruption that Starlink has had on the satellite communications market, companies in the Earth observation sector are closely following the development of a related SpaceX system.Executives with several Earth observation companies said during a panel at World Space Business Week here Sept. 19 that they are keeping tabs on SpaceX’s Starshield system, with some seeing competitive concerns and others opportunities for partnerships.SpaceX announced the Starshield program in late 2022, billing it as a version of its Starlink satellites designed for national security applications. The company said that included Earth observation in addition to communications and hosted payloads.“Starshield launches satellites with sensing payloads and delivers processed data directly to the user,” the company says on its website. The company has provided little other information about Starshield and its...

NASA Space Technology Earth is set to temporarily capture a small asteroid, named 2024 PT5, from September 29 to November 25. Discovered by NASAs ATLAS system, this 10-meter-wide asteroid will make a horseshoe-shaped path around Earth but will not complete a full orbit.Similar to asteroid 2022 NX1, 2024 PT5 is a natural object, likely originating from the Arjuna asteroid belt. While Earth has previously captured asteroids into its orbit, sometimes for complete revolutions, PT5 will escape after 53 days. This brief encounter offers a rare glimpse into Earths interactions with space, showcasing how our planet can influence nearby celestial objects.

NASA Space Technology More than 100 scientists will participate in a field campaign involving a research vessel and two aircraft this month to verify the accuracy of data collected by NASA’s new PACE satellite: the Plankton, Aerosol, Cloud, ocean Ecosystem mission.The process of data validation includes researchers comparing PACE data with data collected by similar, Earth-based instruments to ensure the measurements match up.Since the mission’s Feb. 8, 2024 launch, scientists around the world have successfully completed several data validation campaigns; the September deployment — PACE-PAX — is its largest.From sea to sky to orbit, a range of vantage points allow NASA Earth scientists to collect different types of data to better understand our changing planet. Collecting them together, at the same place and the same time, is an important step used to verify the accuracy of...

Technology tamfitronics In an attempt to push the boundaries of sound technology, Microsoft constructed the world’s quietest room—a state-of-the-art anechoic chamber costing a staggering $10 million.This remarkable room holds theGuinness World Record for the lowest sound level, measuring an astonishing -20.35 decibels.The room’s unique design incorporates layers of sound-absorbing wedges made from fibreglass, creating an environment so silent that it nullifies any noise produced within it.Located at Microsoft’s headquarters in Redmond, Washington, the anechoic chamber is a technological marvel.The chamber is constructed using six layers of concrete and steel, forming a 12-inch-thick shell that isolates it from external noise and vibrations.Inside, the walls, floor, and ceiling are lined with wedge-shaped fibreglass panels that absorb sound waves, preventing them from reflecting into the room.This intricate design ensures that no sound escapes, and none enters, creating an...
