Fiber vs 5G vs Starlink: The Shocking Truth About Internet Speeds, Latency and Costs Worldwide

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 with DOCSIS 3.1, while DOCSIS 4.0 targets up to 10 Gbps down. DSL provides 1–35 Mbps down and 1–10 Mbps up with latency around 20–50 ms, is nearly universal where phone lines exist, and remains the lowest-cost broadband option. Fixed Wireless Access typically delivers 10–100

Sky Wars: The Rising Drone Threat and High-Tech Counter-Drone Warfare

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, and in 2023 the U.S. supplied Ukraine with VAMPIRE kits (vehicle-mounted laser-guided rockets) for drone defense. Counter-drone systems use a layered approach—radar, RF, EO/IR, and acoustic sensors—with Fortem DroneHunter using compact R20 and R30 radars to spot small UAS out to several kilometers. RF detection

AstroForge Brokkr‑2 (Odin) Mission Overview and Objectives

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 content. Odin is a ~120 kg fully fueled deep-space probe built on Orbital Astronautics’ ORB-50 platform, with about 1×1×0.7 m dimensions and an approximate development cost of US$3.5 million. The spacecraft uses electric propulsion with xenon thrusters supplied by Dawn Aerospace, enabling a cruise of

ISRO’s Lunar Success (Chandrayaan-3) and Momentum for Mars Exploration

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 in the lunar south polar region and made India the fourth country to soft-land on the Moon. The mission cost was about $75 million. India’s Mars Orbiter Mission (MOM / Mangalyaan-1) launched on November 5, 2013 atop a PSLV-XL, with a dry mass of about

The Economic Impacts of Blue Origin’s Spaceflights

As of mid-2025, New Shepard had completed about 32 flights (12 crewed) and carried over 60 passengers. Blue Origin’s New Glenn heavy orbital rocket achieved its first successful orbital launch in January 2025. One New Shepard seat was effectively selling for about $1.3 million, well above Virgin Galactic’s roughly $450,000 per seat. NASA awarded Blue Origin a $3.4 billion fixed-price contract in 2023 to develop a Human Landing System for Artemis V. Blue Origin has secured about $8 billion in Space Force National Security Space Launch contracts, including roughly $5.6B in Lane 1 and $2.4B in Lane 2. In early

F-35 Lightnig II Uncovered: Inside the $1 Trillion Stealth Fighter Dominating the Skies

The F-35 is a family of three variants: F-35A conventional takeoff and landing (CTOL), F-35B short takeoff/vertical landing (STOVL), and F-35C carrier-capable version. The aircraft first flew in 2006, with IOC achieved by the F-35B in July 2015, the F-35A in August 2016, and the F-35C in early 2019. As of mid-2025, more than 1,170 F-35s have been delivered worldwide, with the U.S. planning to buy 2,456 and partners adding 900-plus for a fleet exceeding 3,000 by about 2035. Unit flyaway costs for Lot 15–17 averaged $82.5 million for the F-35A, $109 million for the F-35B, and $102 million for

How AI is Reshaping the Future of Warfare – What You Need to Know Now

The 2017 U.S. Department of Defense project Maven was launched to apply AI-based computer vision to analyze drone surveillance footage in the Middle East, with fielding by year’s end. In 2019, China released its National Defense White Paper announcing the goal of “intelligentized warfare” and a plan to become the world AI leader by 2030. The United States established the Joint Artificial Intelligence Center (JAIC) in 2018 to coordinate AI across the DoD, with Joint All-Domain Command and Control (JADC2) linking sensors to shooters in real time. In 2020, DARPA’s AlphaDogfight Trials saw an AI agent defeat a human F-16
