Tips for oxygen-deficient space solar power generation

How will NASA benefit from space-based solar power?

NASA is already developing technologies for its current mission portfolio that will indirectly benefit space-based solar power, the report found. These include projects focusing on the development of autonomous systems, wireless power beaming, and in-space servicing, assembly, and manufacturing.

Can space-based solar power be used for terrestrial energy needs?

ESA commissioned in early 2022, two independent cost benefit studies of Space Based Solar Power for terrestrial energy needs from Frazer-Nash in the UK and Roland Berger in Germany. The studies concluded that:

Could space-based solar power deliver cost-competitive electricity generation?

While requiring substantial development, space-based solar power (SBSP) could deliver cost-competitive electricity generation, de-risking the path by providing a future source of clean, base-load energy by 2040 or earlier.

Why is solar energy a threat to spacecraft?

For missions in the Sun vicinity, the solar intensity rises to 100 suns at 0.1 AU, until 2,500 suns at 0.02 AU, thus, the relative temperature reached at these places can be a threat for spacecraft component and will generate loses in the power generation capability due to loss in the power generation.

How many RD2 solar systems are needed?

Each SBSP design is normalized to deliver 2 gigawatts (GW) of power to the electric grid to be comparable to very large terrestrial solar power plants operating today.3 Therefore, five RD2 systems are needed to deliver roughly the same amount of power as one RD1 system. The functional representation of each design is illustrated in Figure 1.

What kind of power does a space mission need?

Proposed missions include landers, high- and low-altitude balloons, orbiters and microprobes. While short-lived missions could be design using batteries, long-lived in-situ mission require external or internal power sources, such as solar panels or radioisotope power systems (RPS).
