GMH, or genetically modified humans, now have a new name - Spacelings. Spacelings will signify introduced modifications to the human body to permit and allow humans to travel in space unlike ever before.
Every year, the technology is advanced to new levels. Spacelings have advanced to the most important levels of space travel. They can withstand huge G forces during takeoff and acceleration inside the rocket, forces which far exceed what an unmodified human can endure.

A solution is found to protect the human through modification into a Spaceling, protection from deadly penetrating cosmic rays, the solar corona, xrays, and the full range of harmful solar radiation and solar flares. Not yet implemented, but entirely doable in design, a Spaceling can endure long spaceflight by induced E-Sleep. Such induced periods of special sleep will allow missions of great duration and introduce great stamina to the Spaceling astronaut.
The Spaceling has a feature that before was available only to machines. The Spaceling can record the parameters of a space flight, such as the experienced sounds and sights, rocket vibrations, and ambiance of space travel, for playback and further analysis.
