WASHINGTON — The Space Development Agency on Feb. 23 announced a $30 million contract award to AST SpaceMobile to demonstrate its space-based broadband technology for military use. The firm-fixed-price award
TAMPA, Fla. — Aalyria announced a $100 million funding round Feb. 23 that values the Californian venture at $1.3 billion, supporting deployment of laser terminals and software for dynamically routing
Following the successful launch of Ariane 6 in 2025, Europe’s access to space ambitions gain momentum. The launch of the reusable launcher first stage demonstrator Themis T1H under the SALTO
Broad-area change detection only matters if the measurement behind it is stable. In Earth observation, frequency without calibration creates volatility, and imagery without consistency erodes trust over time. EarthDaily was
Humanity gains insight on how to operate in space with every satellite that we launch. True learning comes from doing; otherwise we lock into lab-born biases that come from asking
