SL scientist joins NASA’s simulated Mars mission at Johnson Space Center
Sri Lanka’s Piyumi Wijesekara is among the crew of four volunteers, selected by NASA, to participate in a simulated mission to Mars within a habitat at the agency’s Johnson Space Center in Houston.
Jason Lee, Stephanie Navarro, Shareef Al Romaithi, and Wijesekara 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 June 24 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 Center as they “near” Mars.
This crew is the second group of volunteers to participate in a simulated Mars mission in HERA this year. The most recent crew completed its HERA mission on March 18. Two other missions will follow this year, with the final HERA crew slated to wrap up on Dec. 20.
In a first for HERA, one crew member, Shareef Al Romaithi, hails from the United Arab Emirates (UAE) and will participate in the mission through a partnership between NASA and the UAE’s Mohammed Bin Rashid Space Centre (MBRSC).
As with the previous HERA mission this year, NASA’s Human Research Program is conducting 18 human health studies during the mission. The experiments will evaluate the physiological, behavioral, and psychological responses of crew members in an environment similar to what astronauts will face on a trip to Mars. Seven of these studies are collaborations with the MBRSC and the European Space Agency (ESA). Insights gleaned from the studies will allow researchers to develop and test strategies aimed at helping astronauts overcome obstacles on long missions deep into space.
Wijesekara is a postdoctoral research scientist in the Radiation Biophysics Laboratory at NASA Ames Research Center in California’s Silicon Valley. Her research focuses on developing tissue models to investigate the effects of spaceflight stressors, including ionizing 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.
A group of Tamil Progressive Alliance (TPA) members, including its Leader Mano Ganesan, met President Anura Kumara Dissanayake on Thursday (02) morning at the Presidential Secretariat.
Extensive discussions were held on the issues faced by the Malayagam communities, particularly in relation to education, housing and land, as well as on the urgent measures required to address these concerns. The President paid special attention to all these matters.
Attention was also drawn to the recruitment of qualified Tamil-medium teachers to address the teacher shortage in estate sector schools and this too was discussed at length.
Members of Parliament P. Digambaram and V. Radhakrishnan, along with several other party members, were present at the meeting.
Minister of Foreign Affairs, Vijitha Herath, held talks with Deputy Foreign Minister of Russia Andrey Rudenko at the Foreign Ministry, in Colombo, on Thursday (02), with both sides reaffirming their commitment to strengthening bilateral relations.
The Sri Lanka Ministry of Foreign Affairs said the visiting Russian Deputy Minister noted that Russia regarded Sri Lanka as a long-standing friend.
Rudenko assured that Russia stood ready to support Sri Lanka when required, including in the swift supply of Russian oil to help address the current energy challenges, encouraging Russian investors to explore new opportunities in the country and promoting increased tourist arrivals.
He also expressed Russia’s readiness to provide compensation for Sri Lankan war veterans who had lost their lives in the ongoing conflict between Russia and Ukraine.
Minister Herath welcomed Russia’s willingness to assist, emphasising that Sri Lanka valued the support extended by its “old friend”, particularly at a time when the country was facing pressing energy needs.
He noted that the two countries shared nearly seven decades of diplomatic relations and said the present moment provided an opportunity to further strengthen ties, including through long-term trade agreements.
The discussions focused on enhancing cooperation in the fields of energy, investment, tourism and diplomacy, with both sides reiterating their commitment to further deepen the longstanding friendship between Sri Lanka and Russia.
Police yesterday arrested 157 foreign nationals in connection with an alleged organised online financial scam, conducted from a hotel in the Iranawila area in Chilaw.
The suspects were taken into custody during a raid carried out by the Police while they were staying at the hotel in Iranawila.
Police said the arrested group included 143 nationals from China, 13 from Bangladesh and one from Vietnam.
