November 16, 2022 Dmitry Shulgin

The Air Force Research Laboratory has awarded a $72 million contract to Advanced Space LLC to demonstrate space situational awareness, object detection and tracking in the region of the Moon, supporting a resurgence of interest in lunar exploration and development across civil, commercial and international space agencies.

Cislunar Highway Patrol System (CHPS) — AFRL awards contract for pioneering spacecraft in region of Moon

AFRL’s Space Vehicles Directorate awarded the contract to support the lab’s Oracle spacecraft program, previously called the Cislunar Highway Patrol System, or CHPS. The project has been renamed Oracle after the Oracle of Delphi in ancient Greece. The high priestess of the Oracle would channel the knowledge of Apollo and provide wisdom and foresight to those with whom she would consult.

The name was chosen to acknowledge the accomplishments of the Apollo program and the U.S. Space Force’s commitment to support NASA as they return to the Moon. The Oracle spacecraft is projected to launch in late 2025, with two years of on-orbit experimentation.

«Our primary goals for the program are to advance techniques to detect previously unknown objects through search and discovery, to detect small or distant objects, and to study spacecraft positioning and navigation in the XGEO realm», said Doctor James Frith, Oracle principal investigator.

AFRL often uses the term XGEO to refer to the space beyond geosynchronous orbit out to the Moon, 10 times further than the traditional operational regime for U.S. Space Force and U.S. Space Command. Oracle will operate in the vicinity of Earth-Moon Lagrange Point 1, at a range of about 320,000 kilometers, or about 200,000 miles from Earth. The current Space Surveillance Network has a mixture of sensors on Earth or in traditional orbits like GEO. It is optimized to track satellites at GEO and below, or within distances of 36,000 kilometers, or 22,369 miles.

«Oracle is the culmination of years of ongoing research at AFRL into how to detect and track objects in XGEO given the vast distances, challenges of lunar and solar exclusion, and complexity introduced by the Moon’s gravity», Frith said.

An additional goal of Oracle is to help mature AFRL’s green propellant Advanced Spacecraft Energetic Non-Toxic, or ASCENT, that will carry a refueling port. While there are no specific plans yet to refuel Oracle, AFRL wants to encourage civil and commercial development of on-orbit refueling services.

«We have a great deal to learn when it comes to operating, navigating and communicating from cislunar space and the more distant XGEO region», said Colonel Jeremy Raley, the director of AFRL’s Space Vehicles Directorate. «We look forward to working with Advanced Space LLC, as we deliver novel space capabilities, thereby providing a safe and sustainable cislunar environment».

Space Solar Power

April 28, 2022 Dmitry Shulgin

In honor of Earth Day, the Air Force Research Laboratory, or AFRL, is highlighting its efforts toward harnessing the Sun’s energy, converting it to Radio Frequency, or RF, and beaming it to the Earth providing a green power source for the U.S. and allied forces.

Key technologies need to be developed to make such a challenging process a reality.

In response to this challenge, AFRL formed the Space Solar Power Incremental Demonstrations and Research, or SSPIDR, project to develop the critical technologies needed for such a system. These technologies include further improving solar cell efficiencies; solar to RF conversion and beam forming; reducing large temperature fluctuations on spacecraft components; and deployable structure concept designs.

«A major objective of SSPIDR is to break the one-meter-squared aperture threshold for solar power capture and conversion, and beam that energy to the ground», said James Winter, AFRL principal engineer and SSPIDR project manager. «AFRL will do this with Arachne, SSPIDR’s keystone flight experiment that is anticipated to launch in early 2025».

Other demonstrations of the target technologies include the Space Power INcremental DepLoyables Experiment, or SPINDLE, – a deployable structures experiment still undergoing trade studies, and the Space Power InfRared Regulation and Analysis of Lifetime, or SPIRRAL, experiment – a thermal experiment exploring the concept of using variable emissivity materials to reduce the large temperature swings experienced by spacecraft components on orbit. SPIRRAL is anticipated to launch in 2023 for a test campaign onboard the International Space Station.

«The technologies demonstrated by Arachne, SPINDLE and SPIRRAL will pave the way for an integrated large scale, space-based solar power system capable of collecting solar energy, converting it to RF and beaming it to a receiving station on the ground for conversion to clean, usable power», Winter said.

Colonel Eric Felt, the director of the AFRL Space Vehicles Directorate, considers SSPIDR one of his most important programs.

«An operational system like SSPIDR would provide power ‘on demand’ anywhere on the globe regardless of weather or latitude, day or night and without vulnerable logistics lines», Felt said.

The value of space solar power has been internationally recognized as a foundational capability in need of development.

«This technology will enable expanded space capabilities and give us military advantage, as well as provide economic growth and commerce with more sustainable energy sources». Felt said. «We are excited about the possibilities that the conversion of space solar power energy brings to our national defense and the humanitarian and green energy benefits it will offer to the world».

Drone Killer

March 10, 2022 Dmitry Shulgin

The Air Force Research Laboratory has awarded a contract for Mjölnir, a next-generation counter electronics weapon system, to defend against adversarial drone activity, to Leidos Inc.

Building upon the success of the Tactical High-Power Operational Responder (THOR) technology demonstrator, Leidos will build an advanced High-Power Microwave (HPM) weapon system to bring the newest technology to bear against the growing threat from unmanned aircraft.

«The new prototype will be called Mjölnir, the mythical Norse God Thor’s mighty hammer», said Adrian Lucero, THOR program manager at AFRL’s Directed Energy Directorate at Kirtland AFB, New Mexico. «Because THOR was so successful, we wanted to keep the new system’s name in the family».

The AFRL team, working from Kirtland Air Force Base, are experts in High Power Electromagnetics technology. The THOR demonstrator used bursts of intense radio waves to disable small Unmanned Aircraft Systems (sUAS) instantly.

«The lessons learned from our successful overseas operational testing, now define the new requirements for the Mjölnir program, and will be the baseline configuration for future systems to be deployed around the world», Lucero said.

The $26 million Mjolnir prototype, will use the same technology as THOR, but will add important advances in capability, reliability, and manufacturing readiness.

«We are transitioning AFRL technology to our industry partner Leidos, who has the knowledge and capability to build multiple systems in the future», said Lucero. «Mjölnir will focus on creating a detailed blueprint for all future cUAS HPM systems with enhanced range and technology for detecting and tracking UASs. This will ensure the U.S maintains our electromagnetic spectrum superiority».

AFRL is working closely with cross-service partners to field these systems for base defense.

«As the danger from drone swarms evolves, all services are working closely to ensure emerging technologies like Mjölnir, will be ready to support the needs of warfighters already engaged against these threats. The program will begin this spring with a delivery of the prototype weapon in 2023», said 1st Lieutenant Tylar Hanson THOR deputy program manager.

Thor’s hammer

August 5, 2021 Dmitry Shulgin

The Air Force Research Laboratory’s (AFRL) Directed Energy Directorate is seeking partners to build a new counter electronics weapon system, to defend against the ever increasing threat of adversarial drone activity.

Building upon the success of the Tactical High-Power Operational Responder (THOR) technology demonstrator, AFRL is building an advanced High-Power Microwave (HPM) weapon system to bring their newest technology to bear against the growing threat from unmanned aircraft.

«The new prototype will be called Mjolnir, after the mythical Norse god, Thor’s hammer», said Amber Anderson, THOR program manager. «Because THOR was so successful, we wanted to keep the new system’s name in the THOR family».

The AFRL team working from Kirtland Air Force Base are experts in High-Power Electromagnetics technology. The THOR demonstrator used bursts of intense radio waves to disable small Unmanned Aircraft Systems (sUAS) instantly.

«After a successful 2-year testing campaign, the AFRL team has learned a lot about the benefits of the technology and how it can be improved», Anderson said.

The Mjolnir prototype will use the same technology, but will add important advances in capability, reliability, and manufacturing readiness.

«We are releasing an opportunity for businesses in the directed energy field, to help us build the follow-on system», said Adrian Lucero, THOR deputy program manager. «AFRL’s goal is to create a blueprint for our partners so these systems can be economically produced in large quantities, and to grow a fledgling industry that will become critically important as the U.S. strives to maintain our electromagnetic spectrum superiority».

AFRL is working closely with cross-service partners in the Joint Counter sUAS Office and the Army’s Rapid Capability and Critical Technologies Office.

«As the danger from drone swarms evolves, all services are working closely to ensure emerging technologies like Mjolnir, will be ready to support the needs of warfighters already engaged against these threats. The program will begin this fall with a delivery of the prototype weapon in 2023», said Lucero.

A request for proposal from companies interested in working with AFRL to develop this prototype will be posted on SAM.gov, an official site for companies seeking federal contract opportunities.

The 455th Expeditionary Security Forces Squadron (ESFS) teamed up with a researcher from the Air Force Research Laboratory (AFRL) to teach Airmen how to pilot drones and use them to train coalition forces on how to react to them on the battlefield.

«This is a brand-new program for the 455th AEW, where we are able to test our counter-UAS systems coming into BAF, in addition to running base-wide exercises», said 1st. Lieutenant Ryan Wilkerson, a researcher attached to the 455th ESFS.

Wilkerson, who is not a defender by trade, is deployed out of the AFRL, Rome Research Site, New York, and came to test the program at Bagram Airfield, where the challenge is present in real-world scenarios.

A few defenders assisted Wilkerson, serving as drone pilots and using their own down time to practice piloting and learn tactics the enemy may use.

«It’s exciting to be able to pilot these aircraft for a program no one has ever been a part of before», said Senior Airman Christopher Gallman, with the 455th ESFS joint defense operations center. «I can’t wait to see where it is going and to be able to help out the total force».

The drone pilots wear aviator sunglasses and have an aura of swagger around them, as they take pride in being at the forefront of tactical development.

«It’s fun and enjoyable, and knowing how beneficial it is to not only the base, but all of the force, makes flying the drone worth doing», Gallman said.

Training never ends, and while service members train to deploy, training still continues while deployed.

«This allows us to be better prepared», Wilkerson said. «The best way to train is to actually put something in the air and see how people react. We train how we fight, so this is the most efficient way to counter this growing concern amongst coalition partners».

Tactics used by the enemy are constantly evolving, which is why Airmen are constantly adapting to face threats head-on, ready to engage anything that comes their way.
