'It's an exciting time to be part of space exploration': Peggy Whitson
Veteran astronaut Peggy Whitson is no stranger to firsts. She's spent more days in space than any other American, and is now leading Axiom-4 mission to ISS. In an interview to TOI's Chethan Kumar, Whitson talks about adapting to life in orbit, rise of commercial spaceflight, and why diversity will shape the future of space exploration.
Excerpts:
You've seen spaceflight evolve dramatically. How different is the landscape now?
It's changed a lot. When I started, spaceflight was almost entirely govt-led. Now, companies like Axiom Space are transforming how we explore space. They're not only accelerating innovation but also opening doors for more people and more science ... It's an exciting time to be involved in space exploration.
How do you maintain physical and mental health during extended space missions?
Staying healthy in space is a top priority. We follow a strict exercise routine to counteract the effects of microgravity - things like muscle loss and bone density reduction.
Nutrition is key, too. Mentally, staying sharp means staying connected with loved ones and keeping ourselves intellectually engaged. Whether it's science, reading, or crew activities, it's about finding ways to stay focused and fulfilled.
The ground team's support and the camaraderie with fellow astronauts play a huge role.
You've conducted many spacewalks. What's one challenge that truly caught you off guard?
During one spacewalk, we unexpectedly lost a thermal and micrometeoroid shield. Despite meticulous planning, space has its surprises.

The shield drifted away, and we had to rely on the ground team's rapid thinking to come up with a workaround.
What makes the Axiom-4 mission stand out?
Ax-4 is setting a new benchmark. We're conducting more research studies than any private ISS mission before. It's not just about science-it's about international collaboration... And for countries like India, which have bold space ambitions, missions like this demonstrate how commercial partnerships can help achieve those goals faster.

What is RSV and why are infants especially at risk in India?
Respiratory Syncytial Virus, commonly known as RSV, is the leading cause of respiratory illness in children and infants worldwide. In India, RSV has also become a major issue for parents as well as pediatricians, particularly in the post-monsoon and winter seasons when cases surge. Although the nation continues to establish complete surveillance information, existing studies in tertiary care facilities show that RSV contributes 30% to 50% of bronchiolitis and pneumonia incidents in children aged two years and below. RSV is usually responsible for the symptoms of a cold in older children and adults. Nevertheless, in infants—especially those under six months of age, those who were premature at birth, or those with underlying health issues—the virus may cause severe lower respiratory tract infections, including bronchiolitis (inflammation of small airways) and pneumonia. These two diseases usually require hospitalization, and hospitalization rates between 3 and 5 per 100 infants less than one year of age per year have been estimated in India. The risks are not equal throughout the nation. Geographic and socioeconomic variations account for both the risk of and outcome of RSV infection. Children living in lower-income populations or in densely populated urban environments can have increased exposure from lesser access to healthcare, suboptimal ventilation, and slower diagnosis. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Eat 1 Teaspoon Every Night, See What Happens A Week Later [Video] getfittoday Undo Seeing the international burden of RSV, the World Health Organization (WHO) recently supported maternal RSV vaccination as a prevention approach. This entails immunizing pregnant women so that antibodies are passed on to the unborn child, providing immunity in the vulnerable early months of life. Although not yet included in India's Universal Immunization Programme (UIP), Indian health authorities, such as the Indian Academy of Pediatrics, are in the process of evaluating the vaccine's safety, effectiveness, and affordability in India. Phased introduction in high-risk groups could be the initial step. Apart from vaccines, monoclonal antibodies too have been promising in the prevention of RSV-related complications. These provide passive immunity in a single dose of injection. But the big constraint is cost. Without government incentives or being covered under public health schemes, these therapies could prove to be out of reach for the majority of Indian families. Differential pricing models and collaborations with insurance companies will become paramount in order to expand access. More encouragingly, Indian drug makers are not idle either. Bharat Biotech and Serum Institute of India have initiated RSV research programs and are likely to bank on their experience in the production of pediatric and maternal vaccines. Tie-ups with global firms can also open the way for local production of monoclonal antibodies, leading to costs savings as well as wider availability. Experts put wide availability of RSV vaccines and antibodies in India at least 2 to 4 years down the road. Early access could start in corporate or private hospitals dealing with high-risk pregnancies. In the private sector, however, the incorporation of RSV prevention in the national immunization program will be crucial to making RSV vaccines and antibodies accessible and beneficial for all Indian infants—irrespective of birthplace.

Russia patents drone tech: Orbital station to launch spacecraft automatically; robots to maintain station
Russia patents space technology, uses robots for maintenance of orbital stations (Representative image: PTI) Russia has developed and patented a new technology that allows spacecraft to be launched automatically from an orbital station, Russian news agency TASS reported. This system also includes robotic maintenance features, making it the first of its kind in the world. The technology will be tested at the upcoming Russian Orbital Station (ROS), and later used in future lunar exploration missions . Russia's first deputy Prime Minister Denis Manturov informed President Vladimir Putin about the developments of this technology, emphasising at Russia's need to transition to its own orbital station, module-by-module by 2030. The ROS 'will become the world's first drone platform equipped with robots for its maintenance. This is a patented solution of the Russian Federation,' Manturov said during the meeting on Friday, as reported by PTI. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo The meeting was chaired by Putin through a televised medium to assess the current national projects, particularly in the field of space. Work is currently underway to develop the Russian Orbital Station (ROS), which is planned for deployment in a near-polar orbit between 2027 and 2033. The scientific and power module (SPM), representing the first segment of the ROS, is scheduled for launch at the end of 2027. By 2030, additional components including the universal-node, gateway, and base modules are planned for launch, which together with the SPM will form the station's core infrastructure. The second phase of the station's deployment will involve expanding the facility by docking two target modules between 2031 and 2033. The deployment of Russia's orbital station is expected to begin after the scheduled deorbiting of the International Space Station by 2030. This transition comes after valuable joint space collaboration experience between Roscosmos and Nasa.
