R&D Innovations:

• Laser Retroreflectors for Asteroids & Comets
• Space Surveillance & Tracking (H2020), AIM-DART Mission
• Laser redirection/deviation of asteroids
• Laser retroreflectors for Phobos & Deimos
• Mars center of mass for General Relativity
• Lagrangian-point Laser-ranging Gravity Explorer
• Earth-Moon system, L1; collaboration with INFN-Napoli
• Laser reflectors for Geodetic Reference Antenna in SPace

Asteroids/Comets (NEO, Near Earth Objects)

• COSPHERA to be dropped on asteroid (watch for escape velocity)
• Build COSPHERA to launch it with ESA ‘Asteroid Impact Mission’ (observation of Double asteroid)
• NASA ‘Double Asteroid Redirect Test’

Demonstration of Laser-Ablation Propulsion (LAP)

• Redirect asteroid with TIFPA Italian laser (LAP)
• Measure ToF to reflectors on asteroid with OPTEL-D

Phobos/Deimos surface reflectors

• PANDORA: Phobos ANd DeimOs laser Retroreflector Array
• Reconstruct Mars center of mass to test General Relativity
• GR test improvements with an MGN in the long term:
• PPN Gamma (Sun-Mars)
• Shapiro time delay with Viking landers in the 1970s
• Gdot/G, 1/r2 law at 1.5 AU
• PPN beta (Sun-Mars-Jupiter) not competitive with Moon
• SW: PEP (Planetary Ephemeris Program) by Shapiro, Chandler
