- •
Without daily full sky coverage, PHO threats remain unclear and difficult to assess.
- •
Effective PHO deflection strategies rely on the detection and tracking capabilities.
- •
Infrared telescopes at Earth-Sun Lagrange points L1 and L2 can offer good scanning.
- •
Laser on the Moon’s far side could offer great line-of-sight without threaten Earth.
- •
Encourage to test methods’ TRL of the kinetic impactor, DES, and TND as last resort.
