A coolant leak from a radiator attached to the International Space Station (ISS) interrupted a spacewalk by Russian cosmonauts Oleg Kononenko and Nikolai Chub. The leak occurred while the cosmonauts were inspecting a backup radiator on Russia's Nauka laboratory module. Although the coolant did not reach their suits, the cosmonauts were instructed to leave the area for safety. This is the third incident of a coolant leak from Russian hardware on the ISS, raising concerns about the integrity of the equipment. NASA claims that operations on the ISS are unaffected, with rescheduled spacewalks planned.

During a spacewalk, cosmonauts Oleg Kononenko and Nikolai Chub inspected and isolated a coolant leak from a radiator on the Nauka module of the International Space Station (ISS). While they initially couldn't find the leak, they later discovered traces where the radiator panels were connected. The cosmonauts attempted to clean up the coolant but ran out of towels, resulting in one end of a tether becoming soaked and potentially touching a cosmonaut's visor. The spacewalk also included the release of a nanosatellite and the installation of a synthetic radar communications system, although not all tasks were successful. Managers are still deciding on the next steps for repairing the leak.

Roscosmos cosmonauts successfully completed a spacewalk, inspecting the Nauka module radiator and releasing a nanosatellite. However, they encountered a coolant leak and partial solar sail deployment issues. The cosmonauts wiped down their suits and tools to prevent contamination before reentering the space station. This was the sixth spacewalk for Oleg Kononenko and the first for Nikolai Chub. NASA astronauts Loral O'Hara and Jasmin Moghbeli are scheduled for the next spacewalk to replace faulty equipment and complete maintenance tasks.

Russian cosmonauts conducting a spacewalk outside the International Space Station (ISS) encountered a growing "blob" of coolant leak from an external radiator. One of the cosmonauts' tethers became contaminated, requiring it to be left outside the space station. The cosmonauts isolated and documented the radiator, which had been observed leaking coolant earlier this month. They also noticed small holes on the radiator's panels. The cause of the leak will be determined by Russian engineers using the data collected. The spacewalk also involved the installation of a synthetic radar communications system and the release of a nanosatellite to test solar sail technology.

Russian cosmonauts conducted a spacewalk outside the International Space Station to isolate a leaking radiator and observed residual coolant spewing out into space. One of the cosmonauts attempted to sop up the pooling coolant but was instructed to leave the area when some liquid reached a safety tether. The cosmonauts also worked on attaching a synthetic aperture radar antenna and released a small student-built nanosatellite, although the solar sail propulsion system failed to deploy. The radiator's installation had gone normally, but on October 9, frozen coolant flakes were observed streaming from the radiator. This marks the third coolant leak incident for the Russians in less than a year.

Expedition 70 is underway on the International Space Station (ISS) after two crew handovers and technical issues, including a coolant leak on the Russian segment. NASA astronaut Frank Rubio set a new U.S. space endurance record of 371 days, becoming the first American to spend over one calendar year continuously in space. The crew is preparing for Russian EVA-61 and US EVA-89 later this month. The coolant leak on the Nauka science module has been identified and is not impacting operations. The upcoming spacewalks will involve installing a new camera and replacing a trundle bearing assembly on the solar array rotary joint.

The first all-female astronaut spacewalk since 2019 has been delayed due to a coolant leak outside the International Space Station (ISS). NASA astronauts Loral O'Hara and Andreas Mogensen were scheduled to conduct the spacewalk this week but will now wait until later this year. The coolant leak, which occurred on the ISS's Nauka module, is not toxic or hazardous to the crew but has prompted engineers to assess the conditions outside the station. This spacewalk, which will involve collecting microorganisms, will be the fourth in history with an all-female crew. Another spacewalk, also involving O'Hara, has been rescheduled for October 30.

Russian hardware on the International Space Station has experienced its third coolant leak in less than a year, raising concerns about the viability of Russian equipment in space. The recent leak, originating from a radiator on the Nauka science module, resulted in frozen coolant flakes floating near the station. While the crew was not in immediate danger, the recurring leaks highlight potential issues with Russian space hardware and the aging of the International Space Station. A meeting between NASA, Roscosmos, and other international partners is scheduled to discuss the matter.

A coolant leak was detected on the Russian Nauka Multipurpose Laboratory Module (MLM) of the International Space Station (ISS), but NASA officials have stated that the astronauts were never in any danger. The leak, which involved toxic ammonia flakes, was observed on camera and confirmed by an astronaut on board the ISS. It is unclear whether a spacewalk will be required for repairs or if it will affect a planned spacewalk by NASA astronauts. NASA has emphasized that the leak has no impact on the crew or space station operations. The incident is under investigation, and it is the latest in a series of coolant leaks on Russian ISS equipment in recent months.

The Russian Nauka module on the International Space Station has experienced a coolant leak from its backup radiator, posing no danger to the crew but prompting the closure of window shutters as a precaution against contamination. The primary radiator is still functioning, but the loss of redundancy is not ideal. This is not the first time the Nauka module has encountered issues, with previous incidents including unexpected thruster firing and leaks in other spacecraft. NASA has upcoming spacewalks scheduled, but it remains uncertain if they will proceed as planned.

A radiator on the Russian Nauka module of the International Space Station (ISS) started leaking coolant, marking the third coolant leak incident involving Russian hardware at the station in less than a year. The leak was noticed by flight controllers, and the crew visually confirmed it. The coolant leak was from a backup radiator on the Nauka module, originally from the Rassvet module. Both NASA and Roscosmos confirmed that the station and crew were not in danger, and there were no impacts on space station operations. This incident raises concerns about potential design or manufacturing flaws with Russian spacecraft.

The Russian segment of the International Space Station (ISS) experienced its third coolant leak in less than a year, raising concerns about the reliability of the country's space program. The coolant leak, originating from the backup radiator circuit of the Nauka module, was confirmed by NASA and Russian space agency Roscosmos. While officials stated that the crew and the station were not in danger, the repeated leaks highlight the degrading reliability of Russian space systems. Speculation suggests a potential systematic issue or fault with a subcontractor company. The Russian space sector has been facing difficulties due to funding, failures, and corruption scandals. The ISS remains one of the few areas of cooperation between Russia and the United States amid ongoing tensions.

The Russian space agency, Roscosmos, is investigating a coolant leak on the International Space Station (ISS) that affected a backup radiator circuit on the Nauka module. The primary thermal control circuit is functioning normally, and the crew is not in danger. The cause of the leak is unknown. This incident adds to the mechanical issues Roscosmos has faced in low-Earth orbit, including a coolant leak on a Soyuz spacecraft and a Progress vehicle. Debris in orbit is a growing concern, with the number of uncontrolled objects increasing due to collisions and anti-satellite weapons tests.

Liquid coolant has leaked from the Russian segment of the International Space Station (ISS), specifically from the external radiator circuit, according to Russia's space agency Roscosmos. However, the crew on board the ISS is not in any danger. This incident follows a recent mission where two Russian cosmonauts and an American astronaut spent a year on the ISS due to a Soyuz leak caused by a small meteor impact. The leak poses no threat to the crew's safety, and the ISS remains a rare venue for cooperation between the US and Russia amidst tensions over the conflict in Ukraine.
