Sri Lanka’s Piyumi Wijesekara among new NASA crew for next simulated Mars journey

Sri Lanka’s Piyumi Wijesekera is among NASA’s four-member new volunteer crew selected to participate in a simulated mission to Mars within a habitat at the agency’s Johnson Space Centre in Houston.

Others are Jason Lee, Stephanie Navarro, Shareef Al Romaithi. They will step into the agency’s Human Exploration Research Analog, or HERA, on Friday, 10 May. Once inside, the team will live and work like astronauts for 45 days. The crew will exit the facility on 24 June after they “return” to Earth. Jose Baca and Brandon Kent are this mission’s alternate crew members. HERA enables scientists to study how crew members adapt to isolation, confinement, and remote conditions before NASA sends astronauts on deep space missions to the Moon, Mars, and beyond.

crew members will carry out scientific research and operational tasks throughout their simulated mission to the Red Planet, including a “walk” on Mars’s surface using virtual reality. They will also experience increasing communication delays lasting up to five minutes each way with Mission Control Centre as they “near” Mars.

Piyumi Wijesekara is a postdoctoral research scientist in the Radiation Biophysics Laboratory at NASA Ames Research Centre in California’s Silicon Valley. Her research focuses on developing tissue models to investigate the effects of spaceflight stressors, including ionising radiation and lunar dust on the human respiratory system.

Wijesekara earned her bachelor’s degree in bioengineering from the University of California, San Diego, and her master’s and doctorate degrees in biomedical engineering from Carnegie Mellon University in Pittsburgh, Penn. Her doctoral research focused on stem cell and organ engineering, with an emphasis on engineering lung models that mimic human lung physiology, to study respiratory diseases.

Wijesekara currently lives in San Francisco. She enjoys spending time with family and friends, running along the San Francisco Bay, reading, hiking, volunteering at the food pantry, and attending concerts and musicals.
