Air India cancels multiple flights, cites enhanced maintenance and operational reasons
45:56
NASA has again delayed the launch of the Axiom 4 mission to the International Space Station, originally set for Sunday. This is the seventh postponement since the initial May 29 target. The latest delay stems from a pressure leak on the ISS that needs further assessment. A new launch date hasn't been set, and moving into July could cause scheduling conflicts with an upcoming Russian cargo mission.

10 Indian-origin people who have been part of NASA and its programmes
Image credit: X As India's space program grows stronger with ISRO 's steady achievements, Indians and people of Indian-origin are also making their mark at NASA . From flying missions to leading important research in orbit and on Earth, they have played key roles in many of NASA's major projects. Here's a look at 10 Indian and Indian-origin professionals who have helped shape NASA's success. Kalpana Chawla Kalpana Chawla, an astronaut at NASA, made history in 1997 as the first woman of Indian origin to travel to space. She flew on the Space Shuttle Columbia (STS-87) and again on its final mission (STS-107) in 2003, when the shuttle tragically broke apart during re-entry. Even after her heartbreaking loss, Chawla's legacy continues to inspire students across India and around the world. Sunita Williams Sunita (Suni) L. Williams is a NASA astronaut and U.S. Navy officer of Indian-Slovenian origin who has had a remarkable career in space. Picked by NASA in 1998, she has flown on three missions– Expeditions 14/15, 32/33, and 71/72– and spent 608 days in space. She also holds the record for most spacewalk time by a female astronaut at 62 hours and 6 minutes. In June 2024, she led Boeing's Starliner crewed test flight and, after some technical issues, stayed on the International Space Station before returning home on SpaceX's Crew-9 Dragon in March 2025. Dr. Sharmila Bhattacharya Dr. Bhattacharya, a senior researcher at NASA's Ames Research Centre, is a leading scientist who heads the Space Biosciences division. Her work explores how spaceflight impacts biological systems, particularly immune responses and the effects of radiation, providing critical insights for long-duration human missions. Manisha Ganeshan Dr. Ganeshan studies the planetary boundary layer (PBL) in polar regions using satellite and on-site data. With 10 years of experience using GNSS RO satellites, she provides important data that NASA relies on. Named a Fellow of the International Arctic Science Committee (IASC) in 2017, she also works with NASA Goddard's Global Modeling and Data Assimilation office to improve GEOS models and help predict Polar Lows and tropical cyclones. Swarupa Nune With a background in visual storytelling, Swarupa Nune is a video producer at NASA Goddard who brings climate science and space exploration to life. She has created multimedia features and unique projects, including orchestral collaborations that pair NASA satellite imagery with classical music, helping audiences connect with complex science in creative, engaging ways. Mamta Patel Nagaraja Mamta's career at NASA bridges technical expertise and public outreach. Now serving as Associate Chief Scientist for Exploration and Applied Research at NASA Headquarters, she began her career as an engineer, supporting lunar and planetary missions before moving into leadership and communication roles that help connect NASA's work with a wider audience. Narayanan Ramachandran Ramachandran, a seasoned aerospace engineer at NASA's Marshall Space Flight Centre, supports Jacobs Technology and plays a key role in the Space Launch System (SLS), with a particular focus on diffuser velocity testing for engine systems. Raja Chari Born to an Indian father and raised in Iowa, Raja Chari is an astronaut at NASA who was selected in 2017. In 2021–22, he commanded SpaceX Crew-3 and spent over 170 days aboard the ISS, and he's also part of NASA's Artemis Team, training for future Moon missions. Dr. Kamlesh Lulla Dr. Lulla is a veteran Earth scientist at NASA Johnson Space Centre who has built a long career as Chief Scientist for Earth Observations. Known for his expertise in remote sensing, he has advanced space-based land-use research and helped shape tools for disaster management and environmental monitoring. Dr. Ashwin Vasavada Dr. Vasavada is a planetary scientist at NASA's Jet Propulsion Laboratory and Project Scientist for the Curiosity Mars Rover. He has led key operations studying Mars' climate and geology, helping scientists better understand the planet's history and its potential to have supported life in the past.

5 most unique asteroid facts that one should know
When we think of space, usually planets, stars, or black holes steal the spotlight. But asteroids, which also form a crucial part, are as interesting and full of mysteries that are yet to be studied fully by science. In recent decades, missions like NASA's OSIRIS-REx and Japan's Hayabusa have brought back samples, helping us understand these space rocks better than ever. But despite all we've learned, there are still many surprising things about them that most people don't know. Here are five of the most unique and mind-blowing facts about asteroids The Tunguska event shows their destructive power On June 30, 1908, a massive explosion over Siberia flattened 2,000 square kilometers of forest, yet left no visible crater. Known as the Tunguska event, it's believed to have been caused by an asteroid or comet fragment exploding in the atmosphere. Had it struck a populated area, the devastation would have been catastrophic. This incident is one of the important reasons behind the founding of Asteroid Day. Representative Image Asteroids were once called planets When the first few asteroids, Ceres, Pallas, Juno, and Vesta, were discovered in the early 1800s, astronomers actually classified them as planets. They orbited the Sun just like the others, so the logic made sense at the time. But as more and more of these objects were found between Mars and Jupiter, it became clear they belonged to a unique category. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo By the mid-19th century, the term 'asteroid' became the norm. Interestingly, Ceres had some exceptional traits that is why it was reclassified as a dwarf planet in 2006. Most asteroids live between two planets Today, over a million asteroids have been identified, and the majority of them orbit the Sun in the space between Mars and Jupiter. This region is known as the Main Asteroid Belt. However, asteroids aren't limited to just that area. Some travel near Earth, others remain at Jupiter's Lagrange points, and these asteroids are referred to as Trojan asteroids. A few asteroids even orbit closer to the Sun than Venus. Despite their small size, they're everywhere, and scientists are discovering more with new missions. They are not remains of a broken planet A popular myth suggests the asteroid belt was once a planet that broke apart. But in reality, the total mass of all asteroids in the belt is only about 4% of our Moon. That's not nearly enough to make up a planet. Instead, scientists believe these rocks are leftover building blocks from the early solar system. Due to the powerful gravity of Jupiter, these bits and pieces never formed into a full planet and have been drifting in space ever since. Some asteroids grow tails like comets While comets are known for their glowing tails, some asteroids in the Main Belt have been spotted doing the same. These strange 'active asteroids' occasionally release dust and gas, creating a comet-like appearance. Scientists think this may happen because they contain water ice, which evaporates when exposed to sunlight. In some cases, these could actually be ancient comets that have lost most of their icy material. Either way, they blur the line between two very different types of space objects.
