Indian-American astronaut Sunita Williams and her colleague Barry Wilmore have been stuck at the International Space Station for six months due to a malfunctioning spacecraft. Their rescue mission has been further delayed as NASA announced a delay in the return flight on SpaceX's Crew-9 Dragon capsule. They are now expected to spend close to ten months in space, raising concerns about their health as astronauts require twice as many calories in space due to changes in their metabolism. NASA's Commercial Crew Programme Manager has commended the SpaceX team for their efforts in preparing a new spacecraft for the mission.
International Space Station Crew Faces Extended Stay Amidst Malfunctioning Spacecraft
Indian-American astronaut Sunita Williams and her NASA colleague Barry Wilmore, part of the International Space Station (ISS) Expedition 65 crew, have been stranded in space for an extended period due to a technical issue with their scheduled return spacecraft.
Boeing Starliner Malfunction and Rescue Mission Delay
The astronauts were initially set to return to Earth on Boeing's Starliner spacecraft, which was scheduled to launch in May 2022. However, a malfunction in the spacecraft's propulsion system during an uncrewed test flight in 2021 forced NASA to postpone the rescue mission.
SpaceX Crew-9 Dragon Capsule Return Delays
NASA subsequently planned to use SpaceX's Crew-9 Dragon capsule as a substitute for the Starliner. The Crew-9 mission was set to launch in September 2022, but has since been pushed back due to unspecified issues with the spacecraft.
Extended Stay and Health Concerns
As a result, Williams and Wilmore are now expected to spend close to ten months in space, significantly longer than their initial six-month mission. This extended stay raises concerns about their health, as astronauts require twice as many calories in space due to changes in their metabolism. NASA has expressed confidence in the astronauts' ability to adapt to the extended spaceflight.
Commercial Crew Program Manager Commends SpaceX
Despite the delays, NASA's Commercial Crew Program Manager has praised the SpaceX team for their efforts in preparing a new spacecraft for the rescue mission. SpaceX is working diligently to resolve the technical issues and return the astronauts to Earth safely.

In honor of International Women's Day 2025, Google dedicated a special doodle to celebrate the contributions of women in STEM fields. Despite progress towards gender equality, women continue to remain underrepresented in STEM, making up just 29% of the global workforce. The doodle highlights the groundbreaking achievements of women in space exploration, ancient discoveries, and lab research, while also emphasizing the importance of recognizing and supporting women in STEM. This International Women's Day serves as a reminder of the countless ways in which women have shaped and continue to shape the world through their contributions to science and technology.
A new study analyzing data from prestigious institutions like Harvard and Yale challenges common perceptions about the religious makeup of American college students. Contrary to popular belief, the study found that the biggest divide in religious behavior is not between elite and non-elite institutions, but between political ideologies. The study also found that there are minimal religious differences between selective and non-selective schools, with the main exceptions being higher percentages of Christian and Jewish students at non-selective schools. This study sheds light on the complex relationship between religion and education in the United States.

March 3 is observed as World Wildlife Day every year to bring attention to the importance of protecting endangered species. This year's theme, 'Wildlife Conservation Finance: Investing in People and Planet', highlights the need for sustainable measures to protect our diverse wildlife. The United Nations General Assembly declared this day in 2013, coinciding with the signing of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This international agreement, with 185 parties, aims to regulate and control the trade of endangered species to ensure their survival. Three appendices list the species under different categories based on their level of protection needed, with stricter rules for Appendix I species such as the Indian star tortoise.
India celebrates National Science Day every year on February 28 to honor the discovery of the Raman Effect by Sir C.V. Raman. The theme for this year's celebration, "Advancing Science for a Sustainable Future," highlights the role of scientific research in tackling global issues and encourages discussion on technological advancements. By promoting scientific awareness and inspiring the next generation of scientists and innovators, National Science Day strengthens India's commitment to scientific excellence and sustainable progress.
As the seasons change, our bodies are exposed to fluctuating temperatures and humidity levels that can weaken our immune systems and make us more susceptible to respiratory infections. These shifts in weather can create the ideal conditions for viruses to thrive and spread, leading to common illnesses like colds, coughs, and viral fevers. With insights from Dr Meenakshi Jain, a Senior Director of Internal Medicine, we explore how these seasonal changes affect our health and what steps we can take to protect ourselves. From boosting our immunity through diet and exercise, to practicing good hygiene and getting vaccinated, these preventative measures can help us stay healthy during seasonal transitions.
On the recent National Science Day, we commemorate the discovery of the Raman Effect and celebrate the contributions of scientists like Dr. Chandrasekhara Venkata Raman. To uphold the spirit of innovation, here are some inspiring quotes that continue to motivate scientists, students, and enthusiasts. Meanwhile in Srinagar, a cold wave and light snowfall have hit Jammu and Kashmir, reminding us of the wonders of nature.
India celebrates National Science Day on February 28 every year in honor of Sir CV Raman's groundbreaking discovery of the Raman Effect in 1928, which revolutionized the field of physics and earned him the Nobel Prize. This year, the theme is ‘Empowering Indian Youth for Global Leadership in Science & Innovation for Viksit Bharat’, highlighting the importance of science and innovation in India's development. The first National Science Day was celebrated in 1987, and since then it has become an important occasion to acknowledge the contributions of Indian scientists in various fields.
Skywatchers are in for a celestial treat this week as seven planets - Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn - will be visible in the evening sky. This phenomenon, known as a 'planetary parade', will offer a rare chance to see all seven planets at once until 2040. While four planets will be visible to the naked eye, a telescope will be needed to spot the other two. With a narrow window of just a few minutes after sunset to view them, clear skies and a good vantage point on the horizon will offer the best opportunity to witness this spectacular event.
