by Sandra Erwin AFRL's Space Vehicles Directorate will study the physics of very low Earth orbit, and will pursue sensor technologies for cislunar space WASHINGTON — The Air Force Research Laboratory announced Sept. 2 it will pursue two new space experiments — one will test the performance of satellite instruments in low orbits and the other is to advance sensor technology to monitor cislunar space The experiments are run by AFRL's Space Vehicles Directorate at Kirtland Air Force Base, New Mexico. Col. Eric Felt, the director of the Space Vehicles Directorate, said 27 teams submitted proposals and the two projects that won address important areas of space that impact national security. The experiment known as “Precise” will study the physics of very low Earth orbit, or VLEO, which extends from 90 to 600 kilometers aboveEarth. AFRL said the experiment will examine the ionosphere and how gases impact radio propagation used for communications and navigation. “The experiment will use sensitive satellite instruments and radio waves to examine changes in the ionosphere resulting from different compositions of ion source gases,” AFRL said in a statement. Felt in June during a SpaceNews webinar mentioned that VLEO was an area of interest for AFRL. “This is like where you have to be thrusting all the time just to keep your satellite in orbit, at 200 to 300 kilometers,” Felt said. The second project, named Cislunar Highway Patrol System. or CHPS, will focus on space domain awareness beyond geosynchronous Earth orbit (GEO) all the way out to the moon. “CHPS will explore concepts for object detection and tracking between GEO, where most U.S. Space Force satellites are flown, and the moon,” said AFRL. NASA and commercial companies seek to harvest resources and return to the moon, Capt David Buehler, AFRL program manager said. “This increase in activity will require greater domain awareness. We want to be there providing safety of flight when the U.S. puts boots back on the moon.” The CHPS experiment will investigate sensing technologies and algorithms for object tracking. “We need to address really basic things that start to break down beyond GEO, like how do we even write down a trajectory. The current space catalog uses Two-Line Elements, or TLEs, which simply do not capture the complex orbital dynamics and have almost no meaning in cislunar space,” said Jaime Stearns, principal investigator. The next steps for the project leaders will be to submit budgets, program timelines and specific technical objectives by Oct. 1. At the SpaceNews webinar, Felt said the “best payoff comes from pursuing things that we're not currently doing in space today.” https://spacenews.com/air-force-research-laboratory-announces-new-space-experiments/

The UK's first fleet of uncrewed fighter aircraft is one step closer to reality following a £30-million contract to design and manufacture a prototype in a three-year deal supporting more than 100 jobs in Belfast. Published 25 January 2021 From: Ministry of Defence, Northern Ireland Office, Defence Science and Technology Laboratory, The Rt Hon Brandon Lewis MP, and Jeremy Quin MP The uncrewed combat aircraft will be designed to fly at high-speed alongside fighter jets, armed with missiles, surveillance and electronic warfare technology to provide a battle-winning advantage over hostile forces. Known as a ‘loyal wingman', these aircraft will be the UK's first uncrewed platforms able to target and shoot down enemy aircraft and survive against surface to air missiles. In a boost for Northern Ireland's defence industry, Spirit AeroSystems, Belfast, have been selected to lead Team MOSQUITO in the next phase of the Project. Utilising ground-breaking engineering techniques, the team will further develop the RAF's Lightweight Affordable Novel Combat Aircraft (LANCA) concept, with a full-scale vehicle flight-test programme expected by the end of 2023. Northern Ireland Secretary, Brandon Lewis said: This is fantastic news and underlines the distinct strengths in Northern Ireland's economy, through its advanced engineering and manufacturing capabilities. This ground-breaking project will involve significant investment which will not only support local employment, but also reinforce Northern Ireland's contribution to the security of our nation. Team MOSQUITO, which also includes Northrop Grumman UK, will mature the designs and manufacture a technology demonstrator to generate evidence for a follow-on LANCA programme. If successful, Project Mosquito's findings could lead to this revolutionary capability being deployed alongside the Typhoon and F-35 Lightning jets by the end of the decade. Defence Minister, Jeremy Quin said: This is a great win for the Northern Ireland defence industry and will showcase some of the most pioneering engineering work currently being undertaken in the UK. The £30 million project will accelerate the development of the UK's future air power by delivering cutting-edge uncrewed aircraft, maintaining our position as a world leader in emerging technologies. Working with innovative partners from across the UK, Project Mosquito is transforming traditional approaches to combat air to enable the rapid development of technology. By utilising the latest software development techniques and civilian aerospace engineering and manufacturing expertise, the project will deliver dramatic reductions in costs and development timelines, so their innovations can reach the front-line quicker than ever before. This game changing research and development project will ensure the final aircraft design will be capable of being easily and affordably updated with the latest technology so we remain one step ahead of our adversaries. The aircraft's flexibility will provide the optimum protection, survivability and information as it flies alongside Typhoon, F-35 Lightning, and later, Tempest as part of our future combat air system. Air Chief Marshal Mike Wigston, Chief of the Air Staff said: We're taking a revolutionary approach, looking at a game-changing mix of swarming drones and uncrewed fighter aircraft like Mosquito, alongside piloted fighters like Tempest, that will transform the combat battlespace in a way not seen since the advent of the jet age. Director Future Combat Air, Richard Berthon said: Project Mosquito is a vital element of our approach to Future Combat Air, rapidly bringing to life design, build and test skills for next generation combat air capabilities. Autonomous ‘loyal wingman' aircraft create the opportunity to expand, diversify and rapidly upgrade Combat Air Forces in a cost-effective way, now and in the future. As announced by the Prime Minister in November 2020, the UK's Future Combat Air System (FCAS) programme is set to benefit from a portion of the extra £1.5 billion investment into military research and development, which will help ensure our Armed Forces are prepared to meet the threats of tomorrow. LANCA originated in 2015 in Dstl to understand innovative Combat Air technologies and concepts that offer radical reductions in cost and development time and is a RAF Rapid Capabilities Office led project under the Future Combat Air System Technology Initiative (FCAS TI). The UK MOD's Defence Science and Technology Laboratory (Dstl) provides the project management and is the MOD's technical authority for LANCA and Project Mosquito on behalf of the RCO. https://www.gov.uk/government/news/30m-injection-for-uks-first-uncrewed-fighter-aircraft
