Damaged Russian Soyuz capsule returns to Earth: space agency

[ad_1] Russia's unmanned Soyuz MS-22 capsule returned to Earth on Tuesday from the International Space Station (ISS), landing in Kazakhstan three months after suffering a coolant leak.The vessel landed at 5:46 pm local time (1146 GMT) in the vast Central Asian country, a Roscosmos live transmission showed. The Russian space agency said the capsule carried "around 218 kilograms of cargo", including results of scientific experiments. It landed near the Kazakh town of Zhezkazgan.The capsule flew Russian cosmonauts Dmitry Petelin and Sergei Prokopyev and NASA astronaut Frank Rubio to the ISS in September last year and was due to bring them home.But it began leaking coolant in mid-December -- shortly before Russian cosmonauts were to begin a spacewalk -- after being hit by what US and Russia...

Russia to Bring Soyuz Spacecraft Back to Earth Following Coolant Leak

[ad_1] Russia plans to bring its Soyuz spacecraft back to Earth without its original crew after the vehicle sprang a coolant leak while docked with the International Space Station. Russia plans to bring its Soyuz spacecraft back to Earth without its original crew after the vehicle sprang a coolant leak while docked with the International Space Station. Roscosmos, the state space corporation, also plans to expedite the launch of its next Soyuz to the ISS without a crew to serve as a replacement vehicle to get the astronauts home, according to a Telegram post Wednesday. That launch is now planned for Feb. 20. The three astronauts — two Russians and one American — who flew to space on the original Soyuz will have to stay on the station longer than originally planned. On Dec. 14, Rus...

Russia mulls early return of space station crew after Soyuz capsule leak

[ad_1] Russia's space agency said it is considering a "rescue" plan to send an empty spacecraft to the International Space Station (ISS) to bring home three crew members ahead of schedule, after their Soyuz capsule sprang a coolant leak while docked to the orbiting outpost. Roscosmos and NASA officials said at a news conference on Thursday they continue to investigate how the coolant line of the capsule's external radiator sustained a tiny puncture last week, just as two cosmonauts were preparing for a routine spacewalk. No final decision has been made about the precise means of flying the capsule's three crew members back to Earth - whether by launching another Soyuz to retrieve them or by the seemingly less likely option of sending them home in the leaky capsule without most of ...

Russian space chief praises US after ISS coolant leak

[ad_1] Roscosmos and US space agency NASA said the leak from the Soyuz MS-22 spacecraft did not pose any danger to those on board the ISS. The head of Russian space agency Roscosmos on Tuesday praised Russia-US cooperation at the International Space Station following a major coolant leak from a Soyuz crew capsule."Say hello to the entire American team. They proved themselves to be very worthy in this situation and lent us a helping hand," Borisov said, speaking to the Russian crew on board the ISS. "But I hope we will manage on our own" in the future. "You set an example for the whole world on how to work together in the most challenging and difficult situation. Let many politicians learn from you," he added, according to a transcript released by Roscosmos. Space has remained a rare a...

After coolant leak, temperature is rising on Soyuz capsule docked at the ISS

[ad_1] The temperature on the Soyuz capsule docked at the International Space Station has risen but the crew are not in danger, the Russian space agency said Friday as it assesses a leak. Roscosmos said a number of tests had been conducted following the discovery of a coolant leak on the Soyuz MS-22, and the temperature in the capsule had increased to 30 degrees Celsius (86 degrees Fahrenheit). On Wednesday, the leak forced the last-minute postponement of a spacewalk by cosmonauts Sergei Prokopiev and Dmitry Petelin. The spacecraft is currently under evaluation to ensure it can ferry the two Russian cosmonauts and their American colleague Frank Rubio back to Earth. In a statement, Roscosmos said the "slight change in temperature," was "not critical for the operation of the equi...

Tiny meteorite may have caused leak from Soyuz capsule

[ad_1] Russian and NASA engineers were assessing a coolant leak on Thursday from a Soyuz crew capsule docked with the International Space Station (ISS) that may have been caused by a micrometeorite strike. Russian and NASA engineers were assessing a coolant leak on Thursday from a Soyuz crew capsule docked with the International Space Station (ISS) that may have been caused by a micrometeorite strike. Dramatic NASA TV images showed white particles resembling snowflakes streaming out of the rear of the vessel for hours. The coolant leak forced the last-minute cancellation of a spacewalk by two Russian cosmonauts on Wednesday and could potentially impact a return flight to Earth by three crew members. Russia's space corporation Roscosmos and the US space agency said the leak on t...

Micrometeoroid strike could be cause of Russian spacecraft leak – official

[ad_1] A coolant leak aboard a Russian Soyuz space capsule docked to the International Space Station could have been caused by a tiny meteoroid strike. A coolant leak lasting for at least three hours Wednesday night aboard a Russian Soyuz space capsule docked to the International Space Station could have been caused by a tiny meteoroid strike, a senior Russian space official said Thursday. NASA and Russia's space agency, Roscosmos, said no astronauts were endangered by the leak, which forced mission control officers in Moscow to call off a planned spacewalk by two cosmonauts as fluid sprayed outward into space, as seen on live video during a NASA webcast. "The cause of the leak in Soyuz MS-22 could be a micrometeoroid hitting the ship's radiator," Sergei Krikalev, head of human s...

Horror for astronauts! Micrometeorite caused coolant leak on Soyuz spacecraft, says official

[ad_1] According to a Russian space official, the coolant leak on the Soyuz spacecraft, attached to the International Space Station might have been caused by a micrometeorite. On Wednesday, December 14, NASA reported a “fairly significant” coolant leak on the Soyuz spacecraft which is attached to the International Space Station (ISS). The leak also caused immediate abandonment of the spacewalk scheduled for two Russian astronauts. The sudden coolant leakage was a highly unusual occurrence that perplexed many astronomers. But now, a Russian space official has said that micrometeorites could have been behind the coolant leak. That would mean that a small meteorite had struck the spacecraft to cause the leakage. While rare, this would not be an unheard of event. Earlier this year, NASA r...
