WASHINGTON — Impulse Space has purchased three Falcon 9 launches for its Helios transfer vehicle for missions starting in 2026, including one for the Space Force.
Impulse Space announced Nov. 14 that it signed a contract with SpaceX for the Falcon 9 launches. Each launch will carry the company’s Helios transfer vehicle, a high-energy kick stage the company introduced in January to transport payloads quickly between orbits.
The first launch, planned for mid-2026, will be the first flight of Helios. The transfer vehicle will transport the company’s smaller Mira vehicle, carrying a commercial optical payload, from low Earth orbit to geostationary transfer orbit on the Victus Surgo mission for the Space Force and Defense Innovation Unit. Impulse Space received a $34.5 million contract for Victus Surgo and another mission, Victus Salo, Oct. 3. Impulse Space said the schedule and payloads for the other two Helios launches will be determined later.
China’s latest weapon, unveiled during an air show in Zhuhai, could be a game-changer during possible future conflicts with rival powers.
China is making advancements in its multiple military-related technologies that will give it an edge over its adversaries during a possible conflict in the future. During a recent giant air show in Zhuhai, Beijing unveiled multiple game-changer military technologies, including a mobile air defense weapons system.
Called FK-4000, the mobile air defense weapons system is reportedly capable of intercepting the smallest, lightest drones using its high-power microwaves (HPM).
Debuted by China Aerospace Science and Technology Corporation, the weapon can deliver microwave blasts in less than a second from a distance of almost 2 miles.

Minnesota researchers boost semiconductor transparency and speed for high-power devices.
A team of researchers at the University of Minnesota has developed a next-generation transparent and efficient semiconductor material. This breakthrough could have enormous ramifications for improving the efficiency of high-power electronics, especially those that need transparency, like lasers.
The material is entirely manmade, allowing electrons to travel faster while remaining transparent to visible and ultraviolet light.

The Dstat.cc DDoS review platform has been seized by law enforcement, and two suspects have been arrested after the service helped fuel distributed denial-of-service attacks for years.
The seizure and arrests were conducted as part of “Operation PowerOFF,” an ongoing international law enforcement operation that targets DDoS-for-hire platforms, aka “booters” or “stressers,” to seize infrastructure and arrest the operators.
These platforms are responsible for service disruptions to online services and can cause significant economic damages, as well as impact to the operation of critical services, such as healthcare.
Imagine that instead of viewing an image through a lens, you look through a kaleidoscope that focuses invisible light to obtain a new range of colors. The photon, the ephemeral messenger of light, usually appears alone, but here it appears in a duet, which is the basis of two-photon vision. This is an extraordinary phenomenon in which the human eye, instead of perceiving traditional light, receives pulses of infrared lasers, the gateway to the invisible world.
However, the key to this is measuring the brightness of two-photon stimuli, which until now was only possible for visible light. ICTER scientists have made a breakthrough and determined the luminance value for infrared using photometric units (cd/m2). Thanks to this approach, it is possible to link the luminance of two-photon stimuli to a new physical quantity related to perceived brightness: the two-photon retinal illumination.
Research—conducted by scientists from the International Centre for Eye Research (ICTER) with the participation of Ph.D. student Oliwia Kaczkoś, Ph.D. Eng. Katarzyna Komar and Prof. Maciej Wojtkowski—has shown that the luminance of a two-photon stimulus can reach almost 670 cd/m2 in the safe range of laser power for the eye.
Perhaps no technology has shaped the 21st-century battlefield as profoundly as the drone. These uncrewed aerial vehicles (UAVs), along with their land and sea counterparts, have redefined the way wars are fought by providing military forces with unprecedented capabilities in surveillance, precision targeting, and intelligence gathering — all while reducing the risk to their own personnel. Drones have made complex operations more efficient and less costly, enabling militaries to strike with pinpoint accuracy and maintain a persistent presence over the battlefield.
As the century progresses, the influence of drones continues to expand beyond traditional state actors. Non-state groups and non-peer adversaries increasingly have adopted this technology, leveraging it to level the playing field in conflicts around the world. With commercial drones becoming more accessible, these actors can conduct reconnaissance, drop bombs, and challenge conventional military forces in ways that previously were unimaginable.
The influence of drones flows across all domains of warfare. Loitering munitions, or “Kamikaze drones,” have disrupted traditional force structures by providing smaller, more agile units with the ability to strike high-value targets such as tanks, artillery, and command centers.
