Shortly after the Mercury-Atlas 8 flight in October 1962, some commentators speculated on the possibility of MA-10 being flown as a "dual mission".
The mission would have carried a re-entry communications experiment, which involved injecting water into the plasma sheath surrounding the spacecraft on reentry, in the hope that it would disrupt the sheath enough to allow radio communications; this was later flown on Gemini 3 [REF].
