Ida Scott was the science officer of the crew on Krop Tor researching the black hole known as K37 Gem 5.

Biography
Ida Scott was the science officer in the Walker Expedition, and was researching the previous civilisation who enabled Krop Tor to orbit a black hole and trying to discover the power source that was holding the planet in orbit. She also accompanied the Tenth Doctor down into the pit within the planet. According to the Beast, she was running from her father. (TV: The Impossible Planet)

When the Doctor was suspended from the cable, being lowered into the pit, Ida started to talk about her mother. She paused, implying that Ida was sad that she and her mother would never see each other again, or that her mother had died and she was sad to to think about her. She also said that she was brought up Neoclassic Congregational, which might have been her religion, or maybe just a belief.

While Ida was sitting next to the trapdoor, waiting for contact from the Doctor after he fell to the bottom of the pit, she was rendered unconscious and suffered mild oxygen starvation when her oxygen supply ran out. She was rescued by the Doctor and reunited with her crew after the rocket was beyond the reach of the black hole. (TV: The Satan Pit)

Personality
Ida Scott was very self-confident. She had the ability to command a ship. She acted tough and still maintained calmness and control when she learned that they would soon run out of air, with no way of escape, but pled to the Doctor that he mustn't go because she didn't want to die on her own.

She also was faithful to her crew and found it hard to believe that one of the members of her crew had attacked, and tried to kill, other members. She also grew faithful and loyal to the Doctor and Rose and she started to take orders from them, especially when she and the Doctor were alone in the pit. (TV: The Impossible Planet/The Satan Pit)
