Hubble-5, the twin of Hubble-4 — two 16U satellites built and operated by Spire Global on its LEMUR platform for Hubble Network, and no relation to the space telescope. Hubble Network's idea is that a standard low-power Bluetooth device should be able to report in from anywhere on Earth — a remote field, an ocean crossing — with no phone or cell tower nearby. Launched on SpaceX's Transporter-14 rideshare in June 2025 alongside Hubble Network's own Hubble 6 and 7.
