What We Offer

Rhea Space Activity (RSA) is an astrophysics start-up company in the science and technology industry. Specifically, RSA ideates and creates high-risk/high-reward R&D concepts to support U.S. national security objectives. RSA has developed various technologies in the fields of infrared satellites, directed energy, artificial intelligence, LIDAR, astro-particle physics, small satellites, cislunar operations, intelligence collection, autonomous underwater vehicles and for the F35 Lightening II.

Ideation. We excel in creating high-risk/high-reward astrophysical concepts based on client technologies in order to garner support from government and commercial industry.

management icon

Technical Program Management. Once support is secured for a high-risk/high-reward idea, we provide technical program management expertise in the form of organization, direction, coordination, plan and execution to turn these ideas into reality.

representation icon

Representation. We represent our clients at various government, industry, and investment venues. Our representation seeks to establish valuable partnerships and relations which translate into gain for our clients.

Our Technologies 

RSA’s science-first ethos is predicated on deriving commercial applicability for our earliest-stage technological advancements. RSA’s innovative projects yield tangible security benefits for the United States and Five Eye partners and are easily adaptable to benefit scientific, civil and commercial pursuits.


RSA is providing a gateway to Lunaspatial Intelligence (LUNINT), and to understanding what is happening, and what will soon happen, in cislunar space. RSA is the world's singular trailblazer in the field of LUNINT (a.k.a. LUNAINT and MOONINT) – a new intelligence field our scientists are defining based on aspirational requirements and parameters provided by the U.S. intelligence community and trusted Five Eyes partners. RSA leads the way in defining the hundreds of thousands of miles of open space between the surface of the Earth and the Moon. And, RSA is advancing overall abilities to provide monitoring and analysis of activity on the Moon, as well as the trajectories, and even the intentions, of near-peer competitor spacecraft to benefit U.S. national security, the safety of lanes of space travel between the Earth and the Moon, and the integrity of the Moon’s surface

The RUBY SKY initiative is a ground-breaking, first-of-its-kind project designed to aid the United States and its allies in the detection of “hypersonics,” as near-peer competitors move rapidly toward the development and deployment of hypersonic missile capabilities. Hypersonics represent one of the greatest strategic threats facing the U.S. and its Five Eyes, NATO and Pacific-region partners, and the U.S. defense and intelligence establishments have lauded RSA’s RUBY SKY as a viable, efficient and holistic solution to this looming international challenge. The RUBY SKY project functionally and completely envisions a holistic solution to the hypersonic threat, starting with an innovative space-based optical manufacturing process, combined with origami-like structures to detect hypersonic vehicles within a small-satellite form factor. The aim of RUBY SKY is to cast the brightest of ‘spotlights’ over vulnerable global spots, including near-peer competitor launch areas that are otherwise dark. In time, the greatest advantage of the RUBY SKY project will be to completely nullify any strategic advantage provided to U.S. near-peer competitors by hypersonic vehicles.
