The ship couldn't see the waves of pale green mana, and Khan couldn't perceive them inside the warm membrane of the pilot's technique, so he had to pursue more reckless methods.
Khan wouldn't let his lack of preparations be his doom, so he bided his time, making many trips outside his ship to study the situation. He hoped to find a pattern in the mana released by the planet, but those energy bursts looked completely random, forcing him to rely on simple speed and luck.
The respirators prolonged Khan's time in open space, but catching a stray wave of mana among the dark expanse was too much even for him. After a day spent going in and out of the ship, he decided to bring the vehicle closer to Coravis, hoping the shorter distance from the source would grant him a better starting point.
