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

Published

on

Sri Lanka’s Piyumi Wijesekera has been selected as one of NASA’s four new volunteer crew members for a simulated mission to Mars, taking place within a habitat at the agency’s Johnson Space Centre in Houston.

Joining Wijesekera are Jason Lee, Stephanie Navarro, and Shareef Al Romaithi. The team will enter the agency’s Human Exploration Research Analog, or HERA, on Friday, May 10th. Over the course of 45 days, they will live and work like astronauts before exiting the facility on June 24th, simulating their “return” to Earth. Jose Baca and Brandon Kent serve as alternate crew members for this mission.

HERA provides scientists with insights into how crew members adapt to isolation, confinement, and remote conditions, crucial for preparing astronauts for deep space missions to destinations like the Moon and Mars.

During their simulated mission to the Red Planet, the crew will conduct scientific research and operational tasks, including virtual “walks” on Mars’s surface and experiencing communication delays with Mission Control Centre lasting up to five minutes each way as they “approach” Mars.

This crew marks the second group of volunteers to participate in a simulated Mars mission in HERA this year, with two more missions planned before the end of 2024. Piyumi Wijesekera, a postdoctoral research scientist at NASA Ames Research Centre in California’s Silicon Valley, specializes in developing tissue models to study the effects of spaceflight stressors on the human respiratory system.

Wijesekera holds a bachelor’s degree in bioengineering from the University of California, San Diego, and master’s and doctorate degrees in biomedical engineering from Carnegie Mellon University in Pittsburgh, Pennsylvania. Her doctoral research focused on stem cell and organ engineering, particularly in engineering lung models to study respiratory diseases.

Living in San Francisco, Wijesekera 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.

Eco-Tourism, Climate Shocks, and Economic Resilience Lessons from Australia for Emerging Tourism Economies

Published

on

By

Climate shocks are no longer peripheral risks for tourism economies. They are now central economic variables shaping capital flows, employment stability, insurance markets, and long-term growth prospects. For emerging economies that rely heavily on tourism, climate volatility increasingly determines whether eco-tourism functions as a durable growth strategy or a fragile branding exercise.

Investor and fund manager Arj Samarakoon, widely known as Arj Samarakoon, has repeatedly argued in regional investment discussions that climate resilience should be treated as economic infrastructure rather than an environmental add-on. This distinction is critical for understanding why some tourism economies withstand climate shocks while others struggle to recover.

Australia provides a useful reference point. Despite facing frequent cyclones, floods, bushfires, and prolonged heat events, Australia has maintained long-term confidence in its tourism sector. This outcome is not the result of lower exposure, but of stronger institutional preparation.

Arjuna Samarakoon, widely known as Arj Samarakoon, with his team supporting food and flood relief efforts during climate-related disruptions in Sri Lanka.

Australia’s approach treats climate risk as a structural certainty rather than an exception. Disaster response frameworks, early warning systems, infrastructure standards, and recovery funding are embedded into policy well before crises occur. Tourism operators, insurers, and investors therefore operate within a predictable environment when climate shocks materialise. Research by the OECD shows that such predictability significantly reduces the economic cost of climate events.

For emerging tourism economies, the contrast is stark. Climate shocks often trigger uncertainty that extends well beyond physical damage. Delays in infrastructure restoration, fragmented public communication, and unclear recovery timelines can rapidly erode investor confidence. The World Bank has noted that institutional weakness frequently amplifies the economic impact of climate events in tourism-dependent countries.

Eco-tourism is often presented as a solution to this vulnerability. Nature-based tourism, conservation-led development, and community participation align well with global sustainability preferences. However, eco-tourism remains highly sensitive to climate shocks if resilience is not embedded into governance structures.

Projects marketed as sustainable can fail quickly when floods disrupt access, utilities become unreliable, or insurance coverage tightens. Without institutional resilience, sustainability narratives struggle to translate into stable economic outcomes. This challenge is increasingly recognised in discussions on what Sri Lanka can learn from Australia and the Philippines on economic reform and resilience.

Australia’s experience illustrates that eco-tourism succeeds when resilience is treated as a core economic function. Disaster response systems are designed to preserve continuity, not merely to provide relief. Communication during climate events is coordinated to protect destination confidence rather than amplify uncertainty.

For emerging economies, the lesson is not to replicate Australia’s scale or spending capacity, but to adapt its institutional logic. Climate resilience must be integrated into tourism policy, infrastructure planning, and investment assessment frameworks.

As Arj Samarakoon has noted in investment forums, capital increasingly flows toward destinations that demonstrate governance capacity under stress. In a climate-exposed world, eco-tourism is no longer judged solely by environmental appeal, but by its ability to function through disruption.

Climate shocks will continue to shape tourism economics. Emerging economies that treat resilience as strategy rather than sentiment will be better positioned to convert eco-tourism into a durable source of growth.
