The Timeline of Spaceflight WikiProject has identified this article as requiring cleanup and/or expansion to ensure consistency with other timeline aricles.

Concerns have been raised that:

  • inconsistent date formats are present in the article (d mmmm format should be used throughout)
  • a large amount of launch information is missing
  • an inconsistent dialect is used (British English should be used throughout)
