Oxygen is a 2001 futuristic Christian novel by John B. Olson and Randall S. Ingermanson. Plot Beginning As the novel begins, Dr. Valerie ("Valkerie") Jansen is on a field trip on the slope of Mount Trident on the Alaska Peninsula. In real life, this volcano has not erupted for many years—but in the novel, Mount Trident vents sulfur dioxide into the air, and this gas settles into the valley where Valkerie is encamped. She barely survives the experience, at one point taking the air from the tires of her Jeep, which is the only air available for her to breathe. The next morning, the Chief Administrator of NASA, together with one of NASA's senior physicians, lands on the slope of Mount Trident in a helicopter. They are looking for Valkerie, because they wish to interview her for a position as an Astronaut Candidate. The conversation that follows is very confusing to both sides, chiefly because Valkerie is convinced that Mount Trident is about to erupt and all three must evacuate at once. Eventually, however, Valkerie climbs aboard the helicopter with the two NASA officials. Eventually she is summoned to Houston, Texas, and reports for training at NASA's headquarters complex. A hot dispute between the NASA Administrator and Nate Harrington, the Mars Mission Director, results in her beginning a training regimen that is more grueling than usual, leading her to believe that Harrington wants her dropped from the program on any pretext he can invent. But in fact the NASA brass are very much impressed with her academic record and her seemingly unique ability to cope with "five-sigma" days—days remarkable for a series of dire, often life-threatening crises. (Her breathing the air in her Jeep tires to survive the fumarolic venting incident is a case in point.) As for Mr. Harrington, he has never wanted anything more than to have the NASA administrator respect his prerogatives as Mars Mission Director—and furthermore, he is distracted by a series of events that have nothing to do with Valkerie or her candidacy. Nate's distractions include: a serious budget problem that has forced NASA to sell exclusive broadcast rights to a major television network, a clear threat from a prominent US Senator that he "has the votes" to terminate NASA's flagship program, a compromise of project security that darkly suggests a terrorist plot against NASA (and requires him to have an FBI agent as a
