- Distinguish types of spacecraft, e.g. orbital satellites vs. interplanetary probes, vehicles (cargo, passenger) vs. stations, comsats vs. spysats vs. science observatories (earth- and space-observing), etc.
- The lists of examples are good stubs, but these sections need paragraphs of text too! Sdsds 00:25, 27 March 2007 (UTC)
- Link to life support system for human spaceflights. Sdsds 06:18, 12 April 2007 (UTC)
- Rewrite Manned spacecraft section to talk about the spacecraft instead of a few missions and milestones.
- Clean up style / grammar (e.g. "Currently only a few contries have space capsule technology")
