NASA and Roscosmos are on high alert as cracks in the Russian service module on the ISS continue to worsen, posing a top safety risk. Despite efforts to contain the air leak since 2019, the source remains unknown and has reached record high levels this year. As a precaution, astronauts have been instructed to stay close to their spacecraft, and access to the module has been limited to critical use only. NASA is also working on an emergency evacuation plan for American astronauts, highlighting the urgency of this critical situation. With the ISS facing an increased risk from orbital debris and operating beyond its intended lifespan, the future of the station remains uncertain.
Cracks Worsen in Russian Service Module, Posing Safety Risk on ISS
The International Space Station (ISS) is facing a heightened safety risk due to worsening cracks in the Russian service module, Zvezda. The situation has put NASA and Roscosmos on high alert, leading to emergency precautions and concerns about the station's future.
Background:
The Zvezda service module is a core component of the ISS, providing living and working space for astronauts. However, since 2019, a persistent air leak has been detected in the module, leading to repeated repairs and safety inspections. The source of the leak remains unknown despite extensive efforts to locate and seal it.
Current Situation:
This year, the air leak has reached record high levels, prompting NASA and Roscosmos to take immediate action. Astronauts aboard the ISS have been instructed to stay close to their spacecraft and have limited access to the damaged module for critical use only.
NASA is also preparing an emergency evacuation plan for American astronauts, underscoring the severity of the situation. The station is facing increased risk from orbital debris and has already exceeded its intended lifespan, adding to the uncertainties surrounding its future.
Top 5 FAQs and Answers:
1. What caused the cracks in the Russian service module?
The exact cause of the cracks is still unknown. However, experts believe they may be due to a combination of factors, including age, temperature fluctuations, and exposure to radiation.
2. How long has the air leak been going on?
The air leak was first detected in 2019 and has persisted despite multiple attempts at repairs.
3. Are the astronauts in immediate danger?
Currently, the astronauts are not in immediate danger. However, if the leak continues to worsen, NASA may evacuate American astronauts as a precaution.
4. What is the impact of the air leak on the ISS?
The air leak has reduced the amount of oxygen available to astronauts and has limited their ability to conduct experiments and maintenance tasks.
5. What is the future of the ISS?
The future of the ISS is uncertain due to the ongoing safety concerns and the station's aging infrastructure. NASA and Roscosmos are currently working on a transition plan to a new space station known as Gateway.
Conclusion:
The worsening cracks in the Russian service module on the ISS pose a significant safety risk for astronauts and have raised concerns about the station's future. NASA and Roscosmos are monitoring the situation closely and taking steps to ensure the safety of their crews while planning for potential evacuation scenarios. As the ISS faces ongoing challenges, the long-term sustainability of human spaceflight requires careful planning and international cooperation.
Dr Jitender Rohila, a renowned surgeon and consultant at Fortis Hospital, explains the cutting-edge surgical procedures of HIPEC and PIPAC, which are transforming the treatment of peritoneal surface cancers. These techniques involve delivering heated chemotherapy directly to the abdominal cavity or aerosol chemotherapy under pressure, resulting in improved drug absorption and reduced side effects. While HIPEC is suitable for patients who have undergone cytoreductive surgery for abdominal cancers, PIPAC offers promising options for those with advanced diseases or seeking additional treatment after surgery.
On World Cancer Day, actress Sonali Bendre, who battled cancer in 2018, talks about the importance of early detection and praises the government's Ayushman Bharat initiative for breaking financial barriers and providing accessible and affordable healthcare for cancer patients. Filmmaker-writer Tahira Kashyap and actor Emraan Hashmi also commended the Ayushman Bharat and Pradhan Mantri Jan Arogya Yojana (PMJAY) for making cancer treatment accessible regardless of financial background, on this international day aimed at reducing preventable suffering from cancer.

A team of academics has uncovered valuable insights into Roman legal proceedings through a newly discovered papyrus dating back over 1,880 years. The papyrus, named after Professor Hannah Cotton Paltiel who discovered it, reveals how the Roman empire handled financial crimes involving slaves in Judaea and Arabia. It is the longest Greek papyrus ever found in the Judean desert and sheds light on the prosecutors' notes and trial preparations before the Bar Kokhba revolt.
A metal detectorist in Westphalia, Germany has unearthed a one-of-a-kind find – a tiny gold lock that dates back to the Roman era. Measuring less than half an inch in diameter, this miniature version of a typical Roman lock was likely used to secure precious belongings. With the help of 3-D neutron computed tomography, archaeologists have been able to examine the lock's intricate inner workings, shedding light on its design and functioning. This remarkable discovery raises questions about the prevalence and significance of such precious miniature locks in Roman society.
The annual census of dolphins at Chilika lake in India's eastern state of Odisha has begun, with over 100 people participating in the three-day exercise. Equipped with specialized equipment, a team of retired government officials, researchers, students, and experts are counting the dolphins at India's largest brackish water lagoon. The census aims to track the population of the endangered species, which is listed on the International Union for the Conservation of Nature's Red List. Last year's data was not released due to adverse weather conditions, but in 2023, 173 dolphins of two species were found in the lake. The census is being carried out by the Chilika wildlife division in collaboration with the Chilika Development Authority.
* A team of scientists has developed a new algorithm for calculating the power function, making the process more efficient and accurate. This development could have far-reaching implications for fields such as engineering, physics, and economics, where power calculations are common. Using this new algorithm, researchers can now quickly and accurately determine power values, helping to advance their research and innovations. Furthermore, this method ensures that the resulting values are always non-negative, eliminating the need for post-processing.
As Maharashtra continues to battle against infectious diseases like HMPV and bird flu, health experts are now raising alarm over the rising cases of Guillain-Barre Syndrome (GBS) in several cities of the state. While some studies have linked GBS to the Oxford-AstraZeneca vaccine, others have refuted this claim. However, one thing is clear - GBS is a serious medical emergency that requires immediate treatment to prevent paralysis or even death.

In the animal kingdom, being an alpha male may seem like the ultimate achievement, but a new study shows that for baboons, it comes with intense levels of stress. Despite having dominance, respect, and first dibs on resources, these primates live in constant fear of losing their position and must guard their mates from rival males. This takes a toll on their physical and mental well-being, showing that being at the top is not as great as it may seem.
