Saudi astronauts Rayyanah Barnawi, Ali AlQarni begin research projects aboard International Space Station

  • During their eight-day stay, Saudi astronauts will be undertaking 14 pioneering experiments in microgravity
  • Three of those will be conducted real-time with participation of 12,000 Saudi students across 47 locations

RIYADH: Saudi astronauts Rayyanah Barnawi and Ali AlQarni have started their research projects aboard the International Space Station (ISS), a few days after arriving via the privately-launched Axiom Space 2 mission

During their eight-day stay at the space station, the Saudi astronauts would be undertaking 14 pioneering experiments in microgravity and with three of those to be conducted real-time with the participation of 12,000 Saudi students across 47 locations of the Kingdom.

The involvement of students was aimed at “preparing future astronauts and engineers through quality education and training programs, and participation in scientific experiments, international research, and future space-related missions,” state news agency SPA reported.

The real-time interaction ensures that students can access the Saudi crew live as they simultaneously perform their experiments on Earth and in space.

Barnawi and AlQarni are running six experiments to understand the impacts of being in space, microgravity and a high radiation environment on the human brain and nervous system.

The research aims to evaluate the repercussions of space on human health and the safety of such space trips on the human brain and will utilize novel neuroscience tools including measuring blood flow to the brain and the brain’s electrical activity, SPA said.

The two Saudi astronauts will also do four cell science experiments to investigate the inflammatory response of human immune cells in microgravity.

Their research will be focused on changes in mRNA decay, a process that can turn off inflammation.


Saudi Arabia, Estonia strengthen cyber defense cooperation

Saudi Arabia, Estonia strengthen cyber defense cooperation

  • Renowned for its leadership in digital governance, Estonia sees cybersecurity as central to its partnership potential with Saudi Arabia, building on years of regional engagement through its technology firms

RIYADH: Estonia aims to deepen defense, cybersecurity, and artificial intelligence cooperation with Saudi Arabia as both nations look to advance technology‑driven defense and cybersecurity capabilities.

Hanno Pevkur, Estonia’s minister of defense, told Arab News at the World Defense Show in Riyadh on Monday that Estonia’s defense industry is eager to contribute to the Kingdom’s fast‑growing defense ecosystem.

“In the modern world, cooperation built on trust and technology is the best defense,” he said. “It is important for us to be here because we clearly see there is a possibility to increase cooperation, not only bilaterally between Saudi Arabia and Estonia, but across the region.”

At Estonia’s pavilion, a cooperation agreement was signed between an Estonian company and a Saudi firm during the show, he noted.

Pevkur also said Estonia’s defense sector has expanded rapidly in recent years, driven by technological innovation and partnership.

“Our defense industry is growing very rapidly, and we continue to see strong momentum,” he said.

He said Estonia’s strengths lie in digital and smart‑system integration rather than large‑scale weapons production.

“We will not build airplanes or tanks, but what we can do is integrate robotics, automation and drones to make existing systems smarter,” he said.

The minister said effective defense collaboration must link businesses and governments to achieve meaningful results.

“When we want to have real cooperation, we need it on all levels,” he said. “The biggest client for any defense company is the government, so we must treat this as one ecosystem where the public and private sectors work hand in hand.”

Renowned for its leadership in digital governance, Estonia sees cybersecurity as central to its partnership potential with Saudi Arabia, building on years of regional engagement through its technology firms.

Pevkur said several Estonian companies, including Nortal, have already assisted Gulf governments in developing open IT and digital‑service systems.

“As the most digitalized nation in the world, almost every service in Estonia can be done online, except getting married,” he said. “But with such digitalization, we also need strong cyberdefense.”

He said data protection and digital resilience are treated as matters of national sovereignty in Tallinn, the capital of Estonia.

“Data is what we own. When someone steals that data, it becomes a serious threat,” he added. “That is why cyberdefense is not just about technology, it is about trust, sovereignty and protection.”

Pevkur said Saudi Arabia’s advances in AI offer promising opportunities for collaboration.

“I know that Saudi Arabia is doing great work when it comes to AI,” he said. “For us, as a small country with limited human resources, AI is essential not just for defense but for everyday life.”

Pevkur added that Estonia has launched a national AI strategy to promote responsible development and closer coordination between government and industry. One Estonian company, he said, has developed a system that allows a single operator to control hundreds of drones through AI.

“It is quite easy to put a weapon into the hands of a robot, but we also need to define who is accountable for its actions,” he said.

“The big question for the future is whether we can allow a war to be fought entirely by AI, or if humans must always make the final ethical decisions.”

He said in his conclusion that governments must reach a common understanding on how AI will be used and regulated on the battlefield.
