(I'm assuming the man is doing a spacewalk from a nearby spaceship and came to look at the drone... I'm also describing a space suit for your guy, although feel free to retcon it.)
The man slowly approached the anomaly and the drone, his engineering suit's EVA vectoring thrusters spewing occasional bursts of space propellant to keep the man from approaching too fast or just to dodge small pieces of space debris.
The engineering suits plated outsides kept the man safe if he was to ever touch something dangerous.
As the man approached within 100 meters of the drone he could see that the drone were damaged, it's reciever had also been damaged by whatever had happened.
His suit's onboard sensors also detected unusually high concentrations of gamma radiation in the damaged section, There also were high traces of photons...
