Pull an asteroid produces zero dv?

This setup produces the expected thrust but zero dv. Is this normal? The same ship but the claw on the other end pushing has the expected results (just difficult to steer).

It would appear that the thrust from those engines (or the exhaust plumes, at the very least) are butting up against that asteroid and zeroing out the thrust! If you want to tug an asteroid, you'll have to extend the engine booms so the exhaust plumes don't touch the asteroid at all. I recommend just pushing the asteroid instead.

Perfect example of Newton's Third Law in use.....

Yeah, the game checks that your exhaust plumes are not obstructed for about 10 or 20 meters behind each engine. So for a puller-tug, you want the engines mounted forward, or out on wide booms.

Peeps rately use the ambient light settings, which would really help in an almost all black pic like the above.

Luckily not needed in this case though!

 

OP, what you're essentially trying to do is drive a car with the rear bumper being chained to the road.
