The crucial advantage of NP is it power

Power becomes a key issue when looking at the objectives of human exploration

In view of the 2025-2030  ISECG timeline on future deep space missions


The crucial advantage of Nuclear Power (NP) is it power.

The energy density of NR is orders of magnitude larger than any other power source, in particular of solar panels (SP). A rule of thumb is that above 250 – 300 kWe a NR is ‘better’ than current technology SP, but that depends also on mission, and certainly is true for missions toward the outer planets, since solar power scales with 1/r2 from the sun
