The DY-50 craft were Earth's first modern interplanetary spacecraft, though neither were actually operated (nor designed) to transit even to Luna. Instead, the People's Republic of China (PRC) built the vessels as flight-worthy feasibility studies and successfully proved their viability, leading directly to the DY-100 series.

Notes
- While a vessel of this size should technically require 12-14 crew, it was never intended to operate as a freight transport and since would not be commissioned as a working vehicle, it was only designed to accommodate two crew.
- The DY-50, as a test model, did not have a functioning shuttlebay, though there was a mock-up area designated as one. Instead, during the period of testing for the vessels, crew swaps would occur via the ground-based capsule system at the dedicated connection. The DY-50 never actually operated with the crew capsule attached, though the escape capsule was always available.
- While the DY-50 craft never operated as true freight transports and were only equipped with a rudimentary cargo door, they were rated to carry 400 mt of payload (expandable to 439 mt, if orbitally refit), over 16 times more than the previous re-usable vessel, the NASA Space Shuttle of 8 years earlier. (Technically, the space shuttle and the DY-50 were not re-usable in the same manner, as the DY-50 could not return to a ground position.)
