Astronaut training On June 15, 1995, NASA announced that it was selecting
a new group of astronauts. As a naval officer, Nowak could not apply directly, like a civilian could, but had to submit her application to a review board that would then approve it and forward it on to NASA, which it did. NASA received over 2,400 applications, On May 1, 1996, NASA publicly announced the names of 10 pilot and 25
mission specialist candidates; Nowak was one of the latter. The class of 1996, the 16th group of NASA astronauts, was the largest selected since the first class of Space Shuttle astronauts in 1978, which also numbered 35. They were ordered to report for duty at Johnson Space Center to commence their astronaut training on August 12, 1996. Because there were so many of them, they were often packed into classrooms and training facilities, and called themselves "The Sardines". Nowak and her family moved to Texas, where they built a house in
Clear Lake City. Her husband, another naval flight officer, left active duty in 1998 but continued to fly in the
United States Naval Reserve. He found a job as a space communications contractor with Barrios Technology, an aerospace company, and worked at the Johnson Space Center as a
flight controller at the
mission control center. (center) and

Grand Canyon to study geology, and classwork on the Space Shuttle's many systems. As a mission specialist, she was expected to fly a minimum of four hours a month in NASA's
Northrop T-38 Talon aircraft. Training was conducted in the waters of the
Weightless Environment Training Facility and in the
Boeing KC-135 Stratotanker known as the
Vomit Comet that flies a trajectory that gives the sensation of being in space. She completed her astronaut training in August 1998. On September 28, 1998, she returned to Annapolis along with fellow astronaut alumni
Jim Lovell,
Charles O. Hobaugh,
David Leestma,
John M. Lounge,
Bryan D. O'Connor and
Pierre J. Thuot, for a celebration of the life of
Mercury Seven astronaut
Alan Shepard, who had died two months before. In early 2001, Nowak became pregnant with twins. At the
Astronaut Office, Nowak specialized in the operation of the
Space Shuttle's robotic arm. She also served with the
CAPCOM Branch, the astronauts that worked with the mission control center as the primary communicators with the spacecraft. She performed this duty during the
STS-100 mission in April 2001, when the crew of the installed a
robot arm in the
International Space Station (ISS). In October 2001, she gave birth to twin daughters. Nowak and her husband alternated their work schedules so one of them was always with the children. This arrangement lasted until Richard was recalled to active duty in 2002 to participate in
Operation Enduring Freedom, which effectively left Nowak a single mother with three young children. On December 12, 2002, NASA announced the crew for
STS-118, a mission scheduled for November 2003.
Scott Kelly would be the mission commander, Hobaugh the pilot, and the mission specialists would be Nowak,
Scott Parazynski,
Dafydd Williams, and
Barbara Morgan. The
Space Shuttle Columbia disaster on February 1, 2003, killed seven astronauts on the
STS-107 mission, including three from Nowak's 1996 astronaut class. It was NASA's practice to provide the families of astronauts who had died with a personal casualty assistance officer, and Nowak performed this duty for the family of her close friend
Laurel Clark. Clark's widower, Jonathan Clark, a former NASA
flight surgeon, recalled that: The disaster resulted in a series of schedule and hardware changes. The task of testing all the changes was assigned to
STS-114, the Return to Flight mission, but the list of changes that required testing grew so large that a second Return to Flight mission was added to the schedule to accommodate them. Despite the numbering, this mission,
STS-121, would be the second mission flown after the
Columbia disaster. STS-121 was primarily concerned with testing and developing new hardware and procedures to make Space Shuttle flights safer. It would also re-supply the ISS with equipment and consumables. In January 2004, Nowak participated in an eleven-day cold weather survival training course in Canada with fellow NASA astronauts
Dominic Antonelli and
William Oefelein, Swedish astronaut
Christer Fuglesang, Russian cosmonaut
Dmitri Kondratyev, and Canadian astronaut (and future
Governor General)
Julie Payette. The course commenced on January 19, and included four days of instruction with the
Canadian Armed Forces. They were then dropped off in the wilderness in northern
Quebec and had to make their way back on foot. They covered in eleven days, completing the course on January 29. Nowak had worked together with Oefelein, who had been selected as an astronaut with the
class of 1998, when they were both stationed at Patuxent River in 1995. When Nowak and Oefelein returned to Houston they began an
extramarital affair, which they attempted to conceal. As serving Navy officers, they could have been charged with
conduct unbecoming an officer and a gentleman, which includes
adultery, under the
Uniform Code of Military Justice. Oefelein's wife filed for divorce in February 2005 after discovering emails between him and Nowak. Their divorce was finalized in May 2005. Oefelein moved into a small apartment, to which he gave Nowak a key. She left personal effects there, and she soon became a familiar sight to other residents of the complex.
Space flight NASA announced in December 2003 that STS-121 would be commanded by
Steven Lindsey, with
Mark Kelly as pilot and
Michael Fossum and
Carlos Noriega as mission specialists. They were assigned the task of manipulating the robotic arms of the Space Shuttle and the ISS. The STS-121 mission was originally scheduled for March or April 2005, but was soon postponed to July owing to difficulty implementing all the changes required. During the launch of for STS-114 in July 2005, debris separated from the
external tank, the very problem which had caused the loss of the , and STS-121 was further postponed until a solution to the problem could be found. In February 2006, the mission was rescheduled for a
launch window between May 3 and 22, but in March multiple problems forced a further postponement until July. A prelaunch reception was held for Nowak at the
Kennedy Space Center Visitor Complex, and she was joined by her parents, her husband Richard and three children, family members, and friends from school, Annapolis and the Navy. Among the personal effects she packed for the flight was a small owl figurine of the mascot of Luxmanor Elementary School, a
koozie from Tilden Middle School, a banner from Charles W. Woodward High School, an Annapolis Class of 1985 flag, and her grandmother's engagement ring. On July 1, 2006, the STS-121 crew ate the traditional prelaunch cake decorated with the mission's insignia and boarded
Discovery at
Kennedy Space Center Launch Complex 39B. Nowak was the last crew member to enter the spacecraft, taking her seat as the flight engineer on the flight deck immediately behind Lindsey and Kelly. At 15:42, the launch was scrubbed due to thunderstorm activity in the area. STS-121 successfully launched on July 4 at 14:38. It was the first time a Space Shuttle launch had taken place on
Independence Day. with using the

Leonardo module on the
International Space Station. |alt=refer to caption After
Discovery docked with the ISS, Wilson and Nowak used the
Canadarm to unload the Italian-built
Leonardo Multi-Purpose Logistics Module (MPLM). The of equipment and supplies it contained included the
Minus Eighty Lab Freezer for use in scientific experiments and a
Oxygen Generation System to allow the ISS to support up to six crew members. From the
Destiny laboratory on the ISS, Nowak operated the robotic arm whose installation she had overseen as CAPCOM years before. It was more challenging to operate than the one on the Space Shuttle, since it was larger and had an extra joint. Some of trash, experiment results and broken equipment were packed into
Leonardo, and Nowak and Wilson used the robotic arm to re-stow the module in
Discoverys cargo bay. It was then used to make a final check of the Space Shuttle to ensure that no damage had been done by
micrometeorites or
space debris.
Discovery undocked from the ISS and commenced its two-day return to Earth. In all, she spent 12 days 18 hours and 36 minutes in space, during which she traveled .
Discovery landed at the
Shuttle Landing Facility at the
Kennedy Space Center at 09:14 on July 17.

X Games XII at the
Home Depot Center in Los Angeles from August 3 to 6, and the
Houston Astros game on August 14 at
Minute Maid Park, where the crew met
pitcher Roger Clemens and threw ceremonial first pitches. On September 9, Nowak attended a
tailgate party at the Naval Academy versus
University of Massachusetts football game, where she gave her classmates the Class of 1985 flag she had carried on the Space Shuttle and signed photographs of herself. At half time she presented Annapolis with a Navy jersey she had carried on board
Discovery. She gave a long interview with the ''
Ladies' Home Journal'' for its Mother's Day issue and presented awards at NASA's
Stennis Space Center. She went back to Luxmanor Elementary School and Tilden Middle School where she spoke to the children and attended celebrations at Annapolis for the 30th anniversary of its admission of women, during which she gave a presentation as part of the academy's Forrestal Lecture Series. In December, the STS-121 crew flew to the UK, where they visited the
University of Edinburgh and the
National Space Centre in
Leicester, and spoke at the
University of Leeds, fellow STS-121 crewmember
Piers Sellers's alma mater. ==Orlando International Airport incident==
