    How many in this forum realize, that ISS was almost cancelled in 1993. It was saved by a single vote in the US House.

    https://www.thespacereview.com/article/4045/1

    Much of that commercial spaceflight activity revolves around the ISS, a program that played a central role in all three men’s tenures at NASA. Both Goldin and Bolden (who, for a year in the early 1990s, was assigned to NASA Headquarters while still part of the astronaut corps) discussed the 1993 House vote that rejected a proposal to cancel the station by a single vote, cast by Rep. John Lewis (D-GA), who passed away earlier this year.

    Goldin recalled making a last-second pitch for the program as Lewis approached the House floor. “I jumped in front of John Lewis and started making my 15-second elevator pitch about how the future of America’s space program lies in your hands,” he said. “He broke out laughing, tears were coming down his cheeks, he thought it was so funny.”

    “After I made I my pitch, I said, ‘How are you going to vote?’ And he said, ‘I ain’t telling you,’” he continued. When Lewis voted in favor of the station, “we let out a shriek.”

    "SPACE TRAVELNASA advances plan to commercialize International Space Station"

    https://www.spacedaily.com/reports/N...ation_999.html

    The planned launch of a private commercial airlock to the International Space Station in November will accelerate NASA's plan to turn the station into a hub of private industry, space agency officials said.

    The commercialization plan also includes the launch of a private habitat and laboratory by 2024 and a project NASA Administrator Jim Bridenstine announced on Twitter in May in which actor Tom Cruise will film a movie in space.

    "Oxygen supply fails on Russian segment of ISS, crew not in danger"

    https://www.spacedaily.com/reports/O...anger_999.html

    The oxygen supply system has failed in a module on the Russian segment of the International Space Station (ISS) but the crew is in no danger, Russian space agency Roscosmos said Thursday.

    The oxygen supply system on the Zvezda module on the orbital lab failed late on Wednesday but a second system on the American segment is operating normally, a Roscosmos spokesperson told AFP.

    "Nothing threatens the security of the crew and the ISS," said the spokesperson, adding this repair work to fix the issue would be carried out on Thursday.

    "Air leak rate at Russia's ISS Zvezda module halves after crack sealed with tape"

    https://www.spacedaily.com/reports/A..._tape_999.html

    The air leak rate in the Russian Zvezda module of the International Space Station has halved after the crack in the intermediate compartment was sealed with tape, according to the crew's communication with Earth, broadcast by NASA.

    On Friday, cosmonaut Anatoly Ivanishin informed the Moscow-based Mission Control Centre that the pressure in the compartment had declined by 52 mm Hg to 681 mm Hg over 11.5 hours, while the leak rate had fallen to 4 mm per hour from 7-9 mm per hour.

    The cosmonaut noted that the pressure continued to fall, but at a slower pace. He also suggested trying US patches to seal the crack.

    The fissure causing the leak is 2 and 4 centimeters long. A temporarily patch was used to seal it with Kapton (an adhesive film developed by DuPont in the late Sixties which can exist between -269 and 400 degrees centigrade0.

    https://www.spacedaily.com/reports/T...apton_999.html

    The fissure in the Russian sector of the International Space Station (ISS) is between 2 and 4 centimetres (0.7 -1.5 inches) and was temporarily patched up with Kapton tape, a source from the space industry said.

    "The analysis of the photos suggests that the tear in the Zvezda Service Module is between two and four centimeters long. Cosmonaut [Sergey] Ryzhikov taped it with Kapton [a special tape]," the source said.

    Earlier in the day, one of the crew members, cosmonaut Ivan Vagner reported to the ground force that the crew had found a makeshift solution for the leak which would be to tape it with Kapton, an adhesive film developed by DuPont in the late Sixties which can exist between -269 and 400 degrees centigrade.

    "Air still leaking from Russia's ISS Module despite recent patch, crew says"

    https://www.spacedaily.com/reports/A..._says_999.html

    The pressure in the Zvezda module of the International Space Station (ISS) keeps lowering, although the fissure was patched with Kapton tape, and even faster than before the fix, the crew told the ground control on Tuesday, as broadcast by NASA.

    On Monday, cosmonaut Ivan Vagner said the leak was repaired temporarily. A source in the industry told Sputnik the fissure was about 1 inch long and the space crew used Kapton tape to cover it.

    "The pressure is 670 (millimeters)," cosmonaut Anatoly Ivanishin said, adding that he found some particles under the tape. Earlier, before the hatches were locked, the module had the same pressure as elsewhere on the station -733. The module lost 63 millimeters overnight after the fissure was taped up, compared to the 50 millimeters, before it was fixed.

    They might use the same epoxy that was developed to reinstall tiles on the shuttle, although that was a short term fix to allow the shuttle to reenter the atmosphere. It may not be permanent enough.

    The good news for the ISS keeps flowing. We had 4 new astronauts delivered to the ISS by SpaceX's Crew Dragon's first operational mission. Than the report that the leak has been fixed. Finally the new Russian lab will be delivered next year.

    https://sputniknews.com/russia/20201...smos-confirms/

    The crew of the International Space Station (ISS) has installed a patch on a crack in Russian module Zvezda, which will stop the air leak, a Roscosmos spokesperson told Sputnik.

    The International Space Station’s two Russian astronauts began spacewalking work Wednesday to prepare for next year’s arrival of a long-delayed lab, but had to scrap another chore because of a stubborn bolt.
