How can I consistently launch the rocket?
Solution 1:
You must hit the blue energy tank below the satellite to launch the rocket. Usually, from the point where you start, 1 long and 1 short click on the button to move the laser left do the trick. If you miss, adjust your angle by clicking the buttons for left or right accordingly and remember there's a long and a short click.
Solution 2:
Try two short clicks on "left arrow". Always works for me
