Major David Holbrook, the military commander of the Mars Station for the last three years. He's in his late forties, only married to his job, took this position as his last hoorah before he retires, and has a hard time understanding why women would want to come to this desolate planet.
Mike Carone, also not married in his thirties, saw this job opportunity as a way toward advancement when he returns to Earth. He has been on the station for two years overseeing the labor pool and construction. Mike starts falling in love with Alice when they first meet but can't be open about his feelings until she gets hurt. He would like to see more settlers come to Mars in the future to help with the development processes.
Here is an excerpt of Major Holbrook holding a briefing and another scene where Mike Carone finds Alice has taken off on her own:
The next day three department heads, Engineer Ethan Perkins,
James Penrod, head of construction, and Mike Carone Chief Civil Engineer along with Alice, and Reverend Phillips were seated in the Major’s office. The Major’s secretary near the desk was ready
to take notes on the receiving console.
“Where to put them, that’s a good question,” the Major began,“
Mike what are your thoughts on a good location?”
Mike thought for a second, and then voiced, “Major, I want to know where they are at, I want to see them but I don’t want them close enough to interfere or know what we are doing.”
“I agree with Mike,” James began, “how about a hundred miles to the east, it would be on the other side of this crater from our base.”
“But then we wouldn’t really ‘see’ them, except by our satellite overhead,” the Major explained “I believe in the old saying: I want my friends close, but my enemies closer. Reverend - any thoughts?”
Rev. Phillips cleared his throat, then carefully chose his words, “I think you are correct Major, it is better they are closer so they can be easily watched. The satellite can give us good topography, but not so much what they may do on the ground. I suggest maybe ten miles away.”
“Alice, you have been quiet so far, where do you think our new acquaintances should locate? The Major inquired.
“And where is this man now? The Major asked as his hands tightened into fists.
“He should be working on Safe Room F," Mike explained. "I will leave you here to check out your Corporal when he wakes up. I plan on going down to see Wentworth right now, after all, he is under my command.”
“Make sure your ‘six’ are still here. I don’t want any ahmans wandering around or to get to Wentworth first before we do.”
“Yes, sir, I will call you as soon as we get him into custody.”
Mike immediately stood up and entered the hall. Looking around briefly, he could only see five investigators from his group. Alice was missing!
“Where did Alice go?” he questioned looking around at blank faces.
“Maybe she went to the restroom,” replied James Penrod.
“She walked past me and turned down the hallway,” Benza offered.
“Damn it! That woman went to find Wentworth!” Mike exclaimed and started running back through the hall with the others scrambling after him.
Alice had stopped quickly at her cabin to dress into her protective suit with an oxygen tank. Not a word was spoken to Frederick, who was still in his cage as she dashed from her cabin. Running, as much as one can run
on Mars with a slight trot, she navigated through the hallways right, then left. Her leg, still wrapped within the brace was beginning to ache. Entering an elevator, she was transported down to the tunnel entrance. Flashing her ID badge, she ran through the sliding open doors that closed behind her.
