If you have already completed this specific orb challenge, then you will need to start a new playthrough to use this method!
After starting this challenge, hijack a vehicle and fly it to the orb's location. Continue flying at it, then when you get up close to it, pause the game and select Restart Mission. Before the challenge restarts, the game will unpause for half a second and your vehicle will automatically fly into the orb, collecting it. So by doing this, the challenge isn't completed, but you keep the orbs that you get as the reward. You can do this as many times as desired, as long as you don't actually complete the challenge. As a precaution, save your game as you go in case you would happen to pause the game too late and collect it the normal way, completing the challenge.
I've seen other methods of this glitch that have you punching at the orb or jumping above it before restarting, but this is the absolute easiest way to do it because you have much more room for error with the timing.
