NASA Crew Prepares Sushi Aboard ISS With This Space-Friendly Hack
The crew used ingredients like rice, spam and fish to prepare "space sushi".
Life on the International Space Station (ISS) got a fun and tasty twist when astronauts decided to prepare 'sushi" to mark a special moment together. NASA astronaut Jonny Kim even shared a photograph online to give a sneak peek into their celebration.
On X (formerly Twitter), Jonny Kim shared the story and wrote, 'Space sushi isn't quite the same as the fresh stuff on the ground, but it's not bad! We had a crew celebration recently, and one of our crewmates expressed how much they missed sushi (as do I)."
The crew used simple ingredients available on the ISS— rice, spam, fish and added some gochujang (a Korean chilli paste) and wasabi for extra flavour. Though it was not a fancy meal, it brought smiles to the faces of the crew.
'Space sushi isn't quite the same as the fresh stuff on the ground, but it's not bad! We had a crew celebration recently, and one of our crewmates expressed how much they missed sushi (as do I). So we collected and pitched in our personal supplies of fish, spam and rice, coupled with a dash of gochujang and wasabi, which made for a great meal," Jonny Kim said.

Since everything floats in zero gravity, astronauts have to get creative with how they eat. One clever trick is using tape on the dining table with the sticky side facing up. This simple hack helps keep food items, condiments, and utensils in place, preventing them from drifting away mid-meal.
A curious user asked, 'I understand the requirements for long-term shelf-stable food are tough, but is there any progress in improving the food? Like, can it be at least as good as military MREs? Can it be better, considering it can be much more expensive per portion?"
Replying to him, Jonny Kim said, 'The food up here is actually pretty good. There's a lot of variety. We have thermostabilized options (what you find in MREs), rehydratable options (think Mountain House without the high levels of salt), and various off the shelf products. Will make a post one day to show the different options."
Another one wrote, 'Love sushi too! You guys are the real stars of humanity."
Some people even joked that they wanted to try 'space sushi" themselves, while others were curious about how food works in zero gravity.

400 students participate in Indian Space Education Conference
Erudite Space Education, an ISRO-registered organisation, hosted the Indian Space Education Conference (ISEC) in T-Hub on Thursday, bringing together more than 60 schools, 400 participants, with over 110 projects - aimed at inspiring young people to pursue careers in science and space research. The conference gave students a platform to showcase innovative projects across categories such as robotics in space, satellite design, rocket development and space settlement habitat design. Students worked in teams and presented their work, with the best projects from each school earning a stage presentation. The event featured interactive sessions with ISRO scientists and experts, who encouraged students to integrate space and STEM learning with their regular studies. Several schools were recognised as Space Education Hubs for their efforts in promoting scientific curiosity and innovation. Among the key speakers was India's first cosmonaut, Rakesh Sharma, who addressed participants virtually. He praised ISRO's progress in recent years and told students that while many Indians contribute to NASA, the future lies in strengthening India's own space missions. Former ISRO officials, including Sudheer Kumar, Dr. Seshagiri Rao and Dr. Chiranjeevi, also spoke, stressing the need for students and educators to remain engaged with the latest advancements in the field. P. Vishnu, founder of Erudite Initiatives, said the organisation's mission is to take space education to the grassroots level. 'Our aim is to nurture creativity, problem-solving and scientific curiosity among school students,' he said. The conference also saw participation from educators, researchers and industry leaders, including representatives from IIT Hyderabad, T-Hub and the Hyderabad CBSE Schools network. They welcomed the initiative as an important step in raising awareness of space exploration among young learners.

SpaceX probably took leak in Axiom-4 rocket 'lightly': ISRO chief
ANI ISRO Chairman V. Narayanan addresses an ISRO Press Meet, at National Media Centre, in New Delhi on Thursday. SpaceX had probably taken "lightly" the liquid oxygen leak in the Falcon-9 rocket that launched the Axiom-4 mission to the International Space Station, putting at risk the lives for four astronauts, including Shubhanshu Shukla, ISRO chairman V Narayanan said on said it was at the insistence of ISRO engineers that SpaceX examined the leak detected in the oxidiser lines that carry liquid oxygen to the rocket engines and discovered a crack that could have proved fatal."If with the crack the rocket lifts off, with the vibrations, it will give way the moment it lifts off. Once it gives way, it is a catastrophic situation, nothing else," Narayanan said was addressing a press conference along with Axiom-4 astronaut Shukla and his backup for the mission Prashanth Balakrishnan Nair and Union Minister Jitendra Singh."To their (SpaceX's) surprise also, it was a crack. Finally, everything had to be corrected. Probably, they took it a little lightly," the ISRO chief said. Naryanan said the ISRO team, which has worked on liquid oxygen powered engines for over 40 years, insisted on a complete correction, which was carried out by the SpaceX team."But for the complete correction, it would have ended in a catastrophic situation. We have saved the lives of four astronauts," the ISRO chief said at every stage the four astronauts who were part of the Axiom-4 mission were briefed about the delay and the reasons for credited the Indian education system and ISRO training that led to stopping a faulty rocket from taking off and ensuring the safety of the said before the rocket was moved for the June 11 lift-off, an eight-second test was carried out to understand the performance of the engines before giving clearance for the launch."They completed the tests and when we discussed, they did not open up the results, and only said that the Committees have cleared and we are going ahead with the launch programme," Naryanan said."Probably, they thought it was a minor leakage. That is what was the understanding. It was an oxygen sensor that had picked up. Based on ISRO team's insistence, a complete correction was done by the SpaceX team," he said. Shukla said the SpaceX team, the NASA team, the Axiom team and the ISRO team were very transparent to the crew and there was never any time that they did not know what was wrong and what was happening. "Everybody was always aware of what was happening. Nobody was going to send the rocket out if there was a problem," Shukla said."I am ready to put my life in Dr. Narayanan's hand and whenever he makes a rocket and a vehicle, I am ready to go in that. That is the kind of trust I have on him," said Shukla. The crack and other issues were fixed, but on June 12 NASA announced it was working with Russian space agency Roscosmos to evaluate a leak in the Zvezda module, the Russian-built service module of the ISS that houses key life-support and docking systems. The Axiom-4 mission lifted-off from Cape Canaveral in Florida on June 25 and splashed down in the Pacific Ocean off the California coast on July 15.

Space mission achieved all technical objectives, results encouraging: Shubhanshu Shukla
New Delhi: IAF Group Captain Shubhanshu Shukla on Thursday said that his mission to the International Space Station (ISS) -- a first ever by an Indian -- has achieved all technical objectives, and the results are very encouraging. On June 26, Shukla became the first from the country to reach the orbiting lab. His 18-day stay aboard the ISS was packed with several experiments led by ISRO and other activities on the orbital lab. Speaking at a press briefing in the national capital, Shukla called it the "mission of an entire nation". "We have been able to achieve all our technical objectives,' Shukla said. "We had seven different experiments, ranging from stem cell research to growing sprouts on the space station. Some of them started showing results while we were there. The results were very encouraging,' he said. However, he noted that the data needs to be analysed carefully 'to not jump to any conclusions'. For this purpose, 'all the experiments done on the space station were preserved and then frozen and have been brought back to Earth," Shukla said. Shukla, who piloted the Axiom Space- Mission 4, to and fro along with NASA's Peggy Whitson, described the feeling as 'unbelievable'. "Despite all the training, when you sit on that rocket and when that engine ignites, when they catch fire, it is a very different feeling. From that point of time till the time we splashed down, the experience has been unbelievable. It has been so exciting and so amazing that I really have been struggling to find words of how do I convey to you so that you live that through my words," Shukla said. Sharing his key takeaways from the mission, Shukla said: 'Witnessing and executing a human spaceflight mission like this gives you a lot of knowledge, a lot of information. And these are intangibles; you cannot measure them. You cannot just put everything on paper and write it down. The experience goes much beyond and much deeper than what you are documenting or putting in books".
