NATO allies pledge $1 billion to promote sharing of space-based intel

At a recent summit in Washington, DC, NATO member states pledged over $1 billion to enhance intelligence sharing from national and commercial reconnaissance satellites. This move continues NATO's integration of space assets into military commands, following its recognition of space as a fifth war-fighting domain in 2019 and the creation of the NATO Space Operations Center in 2020. Additionally, NATO announced the establishment of a "space branch" to incorporate emerging capabilities into its security strategy.

SpaceX’s Falcon 9 Grounded After Second Stage Breaks Apart in Space

A Falcon 9 rocket failed to deliver its payload to orbit due to an engine malfunction, a rare issue for SpaceX. The rocket, launched from Vandenberg Space Force Base with 20 Starlink satellites, could not complete the necessary second-stage burn, resulting in the satellites being deployed to a lower orbit. SpaceX has contacted 5 of the satellites and is working to raise their orbits using their ion thrusters.
