ISRO To Plan Second Space Docking Mission Soon, To Approach Govt For Approval
The first uncrewed flight of Gaganyaan is also scheduled to happen later this year, with robotic payload Vyomitra on board.
After successfully demonstrating space docking this year, Indian Space Research Organization Chief Dr V Narayanan said the agency is planning to conduct another space-docking experiment. The Spadex-2 may be launched in the coming three years, subject to government approval.
The space agency is planning a proposal, which will be shared with the government soon. One the approval is granted, it is expected to take another 18 months to complete the preparation.
India recently became only the fourth country in the world to successfully perform space docking with its Spadex experiment which launched on December 30, 2024. The mission involved the launch of two satellites on a single rocket which were docked and undocked in the low earth orbit amid challenging conditions.
'They are currently undocked and drifting independently of each other in space. The good thing is that still have 50 per cent propellant left and further experiments are planned," added the senior scientist.
Spadex-1 was fraught with challenges which the space agency overcame and completed the experiment. The first docking was done on January 16, followed by un-docking on March 13. The second docking was done on April 20, with subsequent un-docking on April 25 following power transfer between the spacecrafts.
The technology is critical for the upcoming Chandrayaan-4 slated to be launched in 2028 which will require multiple docking and un-docking in space.
Dr Jitendra Singh, Union Minister of State for Space who was also present said, 'There are bound to be challenges. But India's record is far better than other countries when it comes to attempting new technological feats in space. Even though we didn't succeed with our first lunar landing, we aced it with our second attempt in 2023."
A significant milestone for upcoming human spaceflight, the test Vehicle-D2 (TV-D2) mission has been designed to simulate an abort scenario and demonstrate the Gaganyaan Crew Escape System. The mission includes sea recovery operations for the Crew Module; mimicking procedures planned for India's first human spaceflight.
Gaganyaan First Uncrewed Flight Later This Year
The first uncrewed flight of Gaganyaan is scheduled in the last quarter of 2025 – most likely December. 'We will be carrying three uncrewed test flights, and two crewed test flights before we undertake the final human spaceflight," said ISRO chief Dr V Narayanan.
India's most ambitious space mission – Gaganyaan – will take three Indian astronauts to the Low Earth Orbit at an altitude of 400 km and bring them safely back to Earth. The space agency has already shortlisted the astronauts – all test pilots from the Indian Air Force who have been undergoing rigorous training for the last two years.
One of the shortlisted candidates, Group Captain Shubhanshu Shukla, a decorated pilot in the Indian Air Force, will also be flying aboard the Axiom Mission-4 scheduled to take off from Kennedy Space Centre, Florida on May 29. With this, he will also become the first Indian to travel to the International Space Station (ISS).
Among the major missions lined up from May to July, ISRO will launch the PSLV-C61 mission carrying the state-of-the-art EOS-09 satellite. Equipped with a C-band synthetic aperture radar, EOS-09 will be capable of capturing high-resolution images of Earth's surface under all weather conditions, day or night.
June will see the highly anticipated launch of the NISAR satellite aboard the GSLV-F16. This NASA-ISRO collaboration aims to study Earth's ecosystems and natural hazards through dual-frequency radar data, combining NASA's L-band payloads with ISRO's S-band contributions. The LVM3-M5 mission, scheduled for July, will cater to a commercial contract with AST SpaceMobile Inc., USA, launching BlueBird Block-2 satellites under NewSpace India Limited's commercial program.

Are weight-loss jabs for dogs the next big thing? Scientists exploring new solutions for pet obesity
Synopsis As pet obesity becomes a growing concern, scientists are exploring weight-loss solutions for dogs, drawing inspiration from human drugs like Ozempic. Biotech firm Vivani Medical is testing OKV-119, a GLP-1 mimic delivered via implant, aiming to help overweight dogs manage their weight. While promising, some experts caution about potential consequences, emphasizing that balanced diets and exercise remain crucial.

Road in Lucknow may be named after astronaut Shux; Fernandes statue likely
Lucknow: Lucknow Municipal Corporation will consider proposals to name city roads after prominent personalities from politics, defence and science in the upcoming executive committee meeting on Aug 22. Tired of too many ads? go ad free now Proposal for installation of a statue of socialist leader George Fernandes, besides naming a road each after astronaut Shubhranshu Shukla and scientist Ram Baksh Singh will be tabled by members of the EC. Statue of former defence minister George Fernandes is proposed near Lesa substation in Vikas Nagar Sector 6. Fernandes, known for his role during the Kargil War and a political career spanning several decades, served as a key figure in national defence and social movements. The link road connecting Basant Vihar Colony to Kanpur bypass highway may be named after Group Captain Shubhranshu Shukla, astronaut from Lucknow who was part of Indian Air Force and recently returned from space mission AXIOM 4. Another proposal seeks to name road near Indiranagar Sector 8, leading to Rani Laxmibai Memorial School, after scientist Ram Baksh Singh, remembered for his pioneering research in developing a chemical method to generate gas from cow dung and plants, a technique that laid the foundation for wider adoption of biogas technology in the country. An executive committee member said the proposals reflect the civic body's intent to honour local and national figures who contributed significantly in their respective fields. Decisions are expected after formal approval in the meeting.

(Image: iStock) Ozempic, Wegovy, and Mounjaro have been making headlines for their role in human weight loss, but the conversation is now shifting from dinner tables to dog bowls. With obesity in pets increasingly described as a 'crisis,' scientists are exploring whether the same drugs used by humans could soon help overweight pups shed extra pounds. A recent report by the Daily Mail highlights how biotech firm Vivani Medical is partnering with Okava to test a dog-friendly version of GLP-1 mimics, the same compounds behind popular 'skinny jabs.' If trials succeed, your Labrador's 'Ozempup' injection may not be science fiction for long. Unlike humans who take semaglutide injections weekly, the canine version—called OKV-119—would be delivered via a tiny implant, similar in size to a tracking chip. The device would sit under the skin and release a steady stream of medication for up to six months. Trials so far suggest it is safe in cats, and if approved for dogs, the product could hit the market as early as 2028. Certain breeds such as pugs, beagles, and labradors are notorious for overeating, often putting them at risk of arthritis, heart disease, and reduced lifespan. Professor Alex German, an obesity specialist at the University of Liverpool, told the Daily Mail that managing weight in dogs is rarely simple. 'There's a massive genetic component that drives the animal to be hungry all the time. Having an alternative approach, such as drugs, could be useful for clinicians on the ground to have an extra option,' he explained. Veterinarians warn that obesity in pets mirrors human struggles. Diet restrictions and exercise plans often fall short, especially for dogs genetically prone to weight gain. While 'therapeutic diets' remain the standard, German stresses that weight management is a 'years-long, often life-long challenge' that leaves many owners frustrated. Not everyone is sold on the idea of medicated pups. Dr. Helen Zomer of the University of Florida cautions that while the science is promising, unanswered questions remain. 'We don't have definitive answers whether it would be a good solution or potential consequences,' she noted, emphasizing that balanced diets and physical activity are still the best strategies for weight control. This isn't the first time pharmaceutical weight-loss solutions have been pitched for pets. Back in 2007, Pfizer introduced Slentrol, a drug designed to suppress canine appetites. While initially welcomed, it was later discontinued after owners reported that their dogs seemed less energetic and less happy. For now, weight-loss jabs for dogs remain in trial stages. But if successful, they could reshape how vets address pet obesity. With the first commercial availability projected for 2028, the question looms: will dog owners embrace medicated implants, or will healthy diets and long walks remain the gold standard?
