The freakish accusation was made against decorated NASA astronaut Anne McClain, who is embroiled in a bitter divorce battle with her former partner Summer Worden. That role included providing financial support, the New York Times report stated, and her lawyer said that she accessed the bank account for that goal and without knowing Worden had requested she no longer do so.
KPRC2 in Houston reported that Worden had a son prior to meeting McClain "conceived through in vitro fertilization carried by a surrogate".
The accused astronaut said that she was only "making sure" that family finances are in order and that there is enough money to support Worden's son, who the partners raised together before they got separated and pay household bills.
Worden and her mother have told the Times that NASA's Office of Inspector General has been looking into the case, although Worden said that the FTC has not yet responded to the identity theft report.
According to Worden, her bank account was accessed without her permission from a Nasa-affiliated computer network.
But Worden may have trouble proving her case, as it is unlikely that NASA will open up its complex and highly secure computer systems for an investigation relating to a divorce settlement.
Rusty Hardin, McClain's lawyer, reportedly said his client "strenuously denies that she did anything improper" and "is totally cooperating" with investigators.
Ms McClain, a decorated pilot, was a West Point graduate who flew more than 800 combat hours in Operation Iraqi Freedom before joining Nasa in 2013.
She was about to take part in the first all-female spacewalk however, her role was cancelled at the last minute over what NASA said was a "problem with the availability of correct suit sizes".
The International Space Station was launched in the late nineties and is operated by five agencies from the U.S., Russia, Japan, Canada and 22 collective European nations.
