Solid-state batteries use a solid electrolyte and lithium-metal anodes, offering 50–100% higher energy density than today’s Li‑ion and 1,000+ cycles with about 95% capacity retention, with Toyota targeting 750 miles per charge and 10-minute charging by 2027–2028. Lithium-sulfur batteries have a theoretical energy density above 500 Wh/kg, and a recent all-solid-state Li‑S cell demonstrated around…

Fiber-optic broadband delivers 100–1000+ Mbps download and upload with latency around 5–20 ms, but availability is limited to about 25–40% of U.S. households and roughly 70% of OECD regions. Cable broadband offers 25–500 Mbps down and 5–50 Mbps up with 15–30 ms latency, is widespread in cities, and can reach up to 1 Gbps downstream…

From 2006 to 2023, violent non-state actors carried out 1,122 drone attacks, with a peak of 265 in 2023. The 2018 Gatwick airport incident highlighted the public-safety risks posed by off-the-shelf quadcopters. The Ukraine war has been described as the first “drone war,” with both sides deploying swarms of small drones for surveillance and strikes,…

In 1965 Lloyd’s of London issued the first space insurance policy for an early Intelsat satellite. In 2019 insured losses reached about $788 million against roughly $500 million in premiums, following major failures such as a Vega launch with a ~$414 million loss. The global space insurance market was valued at about $3.6 billion in…

Odin (Brokkr-2) launched on Feb 26, 2025 aboard SpaceX Falcon 9 as part of Intuitive Machines’ IM-2 lunar mission. Its target was near-Earth asteroid 2022 OB5, about 20–30 meters in size (up to ~100 meters diameter) and suspected to be M-type metal-rich, with a flyby planned roughly 300 days after launch to confirm its metallic…

Chandrayaan-3, launched July 2023, achieved a soft landing near the Moon’s south pole on August 23, 2023, with lander Vikram and six-wheeled rover Pragyan. The mission conducted 14 days of surface operations and returned at least 1100 images and data, including ChaSTE soil temperature measurements to 10 cm depth. Chandrayaan-3 marked India’s first soft landing…
