Chen claimed that CAST has already built a test device for the EmDrive and is being tested in the Low Orbit manned Satellite Tiangong-2.
"The formation of an experimental confirmation platform to fulfill the milli-level micro thrust measurement test, as well as several years of frequent experiments and researches into corresponding interference factors, confirm that in this type of thruster, thrust does exist."
However, while the research brought great news and was admired by many, other critics continued that the idea is inconsistent with Newton's conservation of momentum, which states that a body will not move unless an external force is applied.If such technology is successful, space travel could take humans to the moon in just four hours and to Mars in just a few weeks. But apart from the much-coveted Mars travel, British engineer Roger Shawyer further pointed other major things EmDrive could do for the world.
