Irish 'aquanaut' enjoys a cup of Barry's Tea under the sea
The first Irish 'aquanaut' made sure he had his tea bags from home - while he was 200m under the sea developing new technologies for future missions to Mars.
Meath scientist Dr Marc O Griofa made history during the summer when he was chosen by Nasa to live at the bottom of the sea with six others for eight days.
Dr O Griofa, who is advising students to always reach for the stars, described the experience as "the adventure of a lifetime".
"Here we were planning the next steps to go to Mars and, at the same time, everyone's drinking Barry's Tea," he said.
An expert in telemedicine, Dr O Griofa collected samples from each crew member to evaluate the impact of the underwater environment on the body.
His research will be used for further study into conditions such as Alzheimers, Parkinsons and Muscular Dystrophy.
Dr O Griofa was always passionate about space - and ended up in Nasa after studying medicine and a PhD in biomedical engineering from the University of Limerick.
