- Requires long-lasting spacecraft that can withstand radiation damage (Angel 2006).
- Would need to regularly update spacecraft to avoid failure of fleet and subsequent termination shock.
- Need to reduce launch rate to reduce amount of water vapor and nitrous oxide production, which argues for construction of solar shield elements in space (Roy 2022), such an approach needs development.
