It is enough to provide 2 oz of thrust or force given the test parameters. If applied to an object in space it could move very large objects. The article says that it could cut travel times to Mars down to weeks. This is because you would not have to carry any fuel but also probably indicates that it could be scaled up to provide much more thrust. The NASA results of 30 - 50 mn was 1/1000th of the Chinese results.

Yes but is 2 oz of continuous thrust sufficient to cut months off of the trip to Mars? Accelerating half the way and decelerating the other half. I suppose that you could just put 2 of them on there and then you would have 4 oz of thrust. Would the thrust not be proportional to the amount of energy put in?

Net force
I wonder how much juice it took to get the 50 mN of thrust. Wiki says
quote:
The total force exerted on an 800 by 800 meter solar sail, for example, is about 5 newtons (1.1 lbf) at Earth's distance from Sol,[2]
Could you generate enough electricity to overcome the force of a solar wind and fly directly at the sun?

The drive is almost certainly a hoax that a few people at Nasa have been hoodwinked into accepting.
It will work just fine. They just didn't mention the part where you add the popcorn.
