The following is a statement from acting NASA Administrator Robert Lightfoot on the passing of visionary physicist Stephen Hawking, who died at his home in Cambridge, England, early Wednesday morning.

ā€œToday, the world lost a giant among men, whose impact cannot be overstated. Our condolences go out to the family and friends of Stephen Hawking.

ā€œStephenā€™s breakthroughs in the fields of physics and astronomy not only changed how we view the cosmos, but also has played, and will continue to play, a pivotal role in shaping NASAā€™s efforts to explore our solar system and beyond.

ā€œAlong with groundbreaking and inspiring work came another attribute that made Stephen a hero not just to younger generations, but also to his peers. A longtime friend to NASA, Stephen was a passionate communicator who wanted to share the excitement of discovery with all.

ā€œHis loss is felt around the world by all he inspired with his work and his personal story of perseverance.ā€
