Astronaut to undergo NASA medical, psychological testing

[coffeediver]

ORLANDO, Florida (CNN) -- Astronaut Lisa Nowak was taken to the Johnson Space Center in Houston Wednesday for a medical evaluation, which would also include a psychological evaluation, NASA said.

Nowak flew home to Houston Wednesday morning, a day after she appeared in court in Orlando, Florida, to face charges including the attempted murder of a romantic rival.

NASA said she went straight from the airport in Houston to the Johnson Space Center. "She's not staying here. She's leaving with her family," a NASA spokeswoman said, according to The Associated Press.

As friends and strangers tried to imagine what could have caused her apparent meltdown, a few clues emerged.

A family statement said Nowak had recently separated from her husband of 19 years, who works at NASA Mission Control. They have a teenage son and young twin daughters.

The AP reported that there had been signs of problems before Nowak's arrest. In November, police were called to Nowak's home near the Johnson Space Center after a neighbor reported hearing the sounds of dishes being thrown inside, AP reported.

Nowak, a Navy captain, is accused of accosting Air Force Capt. Colleen Shipman, 30, in the parking lot of Orlando International Airport early Monday and attacking her with pepper spray. She told police she only wanted to talk with Shipman. (Full story)

Nowak and Shipman were both "in a relationship" with Navy Cmdr. Bill Oefelein, another astronaut, according to a police report of the incident.

Nowak told police her relationship with Oefelein was "more than a working relationship and less than a romantic relationship."

Shipman has filed for a restraining order on Nowak in Brevard County, Florida, where Shipman lives and works, according to a copy of the order on the county's Web site.

In the paperwork for the order, Shipman said that Nowak had been stalking her for the past two months.

Her handwritten petition says she has known Nowak since Monday at "approx 0345" and adds Nowak is an "acquaintance of boyfriend." (Read Shipman's petition)

A hearing for the order is scheduled for February 20.

Friend: Nowak helped my son

Jonathan Clark, a friend of Nowak and her husband, appearing on CNN's American Morning, called Nowak "a wonderful, good, caring person" who "was a mother before she was an astronaut."

Clark is a former NASA flight surgeon whose wife, Laurel Clark, was among the astronauts killed in the Columbia disaster in 2003.

Nowak helped his son, Ian, cope with the anguish of losing his mother, Clark said.

"Lisa just stepped right in there with us, obviously my son losing his mom had this tremendous void in his life," Clark said. "It was just a wonderful thing, you could just see a smile on his face whenever he was around her."

"All of the female astronauts who are moms have a common bond there," Clark said. "This is a high-risk endeavor and they're almost torn between being a mom and being a career astronaut."

Nowak, who has been an astronaut since 1996, flew her first shuttle mission last July, serving as a mission specialist aboard the Discovery. She and crewmate Stephanie Wilson were known as "the robochicks" because of their work with the shuttle's robotic arm, AP reported.

Grounded

NASA grounded Nowak for 30 days on Tuesday.

Michael Coats, director of NASA's Johnson Space Center in Houston, issued a statement saying Nowak "is officially on 30-day leave and has been removed from flight status and all mission-related activities."

"We are deeply saddened by this tragic event. The charges against Lisa Nowak are serious ones that must be decided by the judicial system," the statement said. (Watch how police say a NASA love triangle went awry Video)

A NASA spokeswoman said Wednesday that Oefelein had flown to the Kennedy Space Center in Florida and was cooperating with investigators.

Family shocked

Nowak's family released their statement from their home in Rockville, Maryland.

"Lisa is an extremely caring and dedicated mother to her three children. She has been married for 19 years, although she and her husband had separated a few weeks ago," the statement said.

"Considering both her personal and professional life, these alleged events are completely out of character and have come as a tremendous shock to our family," the statement said.

"We hope that the public will keep an open mind about what the facts will eventually show and that the legal system will be allowed to run its course."
