SC17: Charles Radley

Spacecraft systems engineer who has worked on manned and unmanned spacecraft development and operations. In 1981 he started work on communications satellite systems integration, launch campaigns and range safety. He was a member of the subcontractor teams for the Galileo and Magellan space probes, experiments for Spacelab-MSL-1 and several communications satellite projects (e.g. Intelsat-6, Olympus, HS-601, HS-376, Inmarsat-2, Marecs).

He worked on the Mobile Transporter, and the power system for NASA Space Station Freedom which became the International Space Station.  He has integrated and tested embedded software systems (missile electronics and spacecraft), conducted real time flight operations for geostationary spacecraft, LEOP and on-orbit    He has extensive involvement in NASA Payload Safety certification and Range Safety processes;   performed hazards analyses, requirements flowdown, verification and validation for commercial and government spacecraft, and ground support equipment (electrical and mechanical)

He was senior systems engineer on the proposed Trailblazer lunar orbiter spacecraft of Transorbital Corporation, 1999 – 2006.

At NASA Kennedy Space Center, FL 2015 –2016  - Software Safety Engineer, Independent verification and validation of the NASA Commercial Crew Program for Office of Safety and Mission Assurance.  Reviewed Hazard Reports from Boeing and SpaceX, crewed spacecraft and launch vehicles.

2015-2016 Supported Asteroid Initiatives LLC in feasibility study of Cubesat+picosat swarm for ESA Asteroid Impact Mission [cancelled in 2016], negotiated related NASA KSC Space Act Agreement to test swarm on the VAB.

Scientific return of a lunar elevator


A Lunar Space Elevator [LSE] can be built today from existing commercial polymers; manufactured, launched and deployed for less than $2B.   A prototype weighing 48 tons with 100 kg payload can be launched by a single SLS, and will pay for itself in 50 sample return cycles.  It reduces the cost of soft landing on the Moon at least threefold, and sample return at least ninefold.  Many benefits would arise.  A near side LSE can mine valuable resources and ship to market in cislunar space, LEO and Earth’s surface.  A far-side LSE can support a super sensitive radio astronomy facility on the lunar surface.  It can also boost payloads into deep space.
