Russian astronauts complete spacewalk to prepare ISS for Nauka

10:37 am

Two Russian astronauts yesterday successfully completed an almost seven-hour spacewalk removing and repositioning equipment to prepare ISS for the arrival of Nauka next year, Russia’s next module for ISS.

The Pirs module will be removed and junked next year to make room for the research lab Nauka — Russian for “science.” Several Russian-directed spacewalks will be required to deal with all this. The plan calls for attaching a cargo ship to Pirs in order to guide it to a fiery reentry.

The new 22-ton lab — stretching 43 feet (13 meters) long — is so big that it will be launched from Kazakhstan by a powerful Proton rocket. Once at the orbiting outpost, it will double as an air lock and docking port.

Earlier it had been announced that they would also do an inspection of the area on Zvezda where they had also discovered a small crack, the cause of the longstanding leak on the station. It appears they did not do this. probably because astronauts inside the station had placed a new permanent patch on the leak, and the work they were doing during the spacewalk carried a higher priority.

Expect that inspection to eventually occur, but for now the cause of that crack remains unknown.

Israeli fighter pilot to fly on Axiom’s first private Dragon launch in ’21

9:24 am

Capitalism in space: Axiom has revealed that an Israeli fighter pilot, Eytan Stibbe, will be the second passenger on on its first private Dragon launch to ISS in the fall of 2021.

Stibbe will be the second Israeli to fly in space, following Ilan Ramon, who died when the space shuttle Columbia broke up in 2003 during its return to Earth.

The Axiom AX-1 mission is scheduled to launch in the second half of 2021, which the company unveiled in a deal with SpaceX earlier this year. Astronaut Michael Lopez-Alegria, who previously worked for NASA and flew to space four times, will be the AX-1 mission commander, with Stibbe set to serve as a mission specialist.

AX-1 would be the first fully private mission to the International Space Station, with Lopez-Alegria and Stibbe flying with two other yet-to-be-named people.

The consistent rumors are that actor Tom Cruise and a movie director will be those other two passengers, but this is not confirmed.

It is important to emphasize that this space mission will be entirely private, with almost no involvement of the U.S. government other than providing coordination, the training of the astronauts, and the use of ISS. The rocket and spacecraft are SpaceX’s, purchased by the customer Axiom. Moreover, Axiom has plans to add its own private modules to ISS where future private space passengers will be housed, which will then reduce the government’s role and contribution even more.

And since this will be a private mission, it means the funds to fly it will come from its passengers, not the government. This also means that as long as there are customers, there will be no slow-down in future flights.

Resilience has docked with ISS

9:52 pm

SpaceX’s Resilience Dragon capsule successfully docked with ISS tonight.

They are in the process of checking the seal of the docking, and the opening of the hatch.

As much as I have been critical of Boeing in recent years, I truly hope they can get their management and engineering problems worked out so they can accomplish the same thing with their Starliner capsule. The competition with SpaceX will be healthy for both companies, the nation, and the future of the human race.

Falcon 9 launch on November 15, 2020 with four astronauts

Capitalism in space: SpaceX tonight successfully launched four astronauts to ISS on its Dragon capsule Resilience, using its Falcon 9 rocket.

They also recovered the first stage, landing it on its drone ship in the Atlantic. The routine manner in which SpaceX ran this launch is truly admirable. They make landing and reuse of the first stage so expected it is hard to believe that for fifty years rocket managers and engineers insisted it wasn’t doable.

They had one issue today, a failure of the capsule hatch to hold air pressure after closure. They calmly reopened the hatch, cleared the issue, added some lubricant, and closed the hatch, all in less than ten minutes.

Resilience will dock with ISS tomorrow evening.

The leaders in the 2020 launch race:

30 China
20 SpaceX
5 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. now leads China 32 to 30 in the national rankings.

Watch today’s launch of SpaceX’s Resilience manned capsule

10:06 am

According to a NASA report yesterday, the weather then stood at 50% for allowing a launch of four astronauts to ISS on SpaceX’s Resilience capsule tonight at 7:27 pm (Eastern).

That percentage was still reported this morning. Part of the issue is that SpaceX wants to recover the first stage, and the weather therefore not only has to be good in Florida, it has to be good in the Atlantic where the stage will come down.

NASA’s live coverage begins at 3:15 pm (Eastern). The link to that live stream is below the fold. As I write this at around noon (Eastern) it is simply NASA TV’s normal feed, which is essentially full time propaganda for NASA. After 3:15 pm it will switch to live coverage, which unfortunately will still be packed with pro-NASA propaganda, even though this launch is entirely being run by the private company SpaceX. NASA’s only part is that of a customer, with the ability to say “no” at any point. The rocket, the capsule, the launchpad, and the countdown, is operated completely by SpaceX and its employees.

I have also added the clean feed from NASA, which appears to carry little commentary or narration.

Weather forces one day delay in launch of Resilience with four astronauts

9:26 pm

Because of high winds and ocean weather interfering with the recovery of the first stage, NASA and SpaceX today decided to delay the launch of SpaceX’s second manned Dragon mission, the capsule Resilience carrying four astronauts, to Sunday, November 15.

NASA and SpaceX are now targeting 7:27 p.m. EST Sunday, Nov. 15, for liftoff of the agency’s SpaceX Crew-1 mission to fly astronauts from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to the International Space Station.

Teams moved the launch by one day because of onshore winds and to enable recovery of the first stage booster, which is planned to be reused to launch the Crew-2 mission next year. The booster is expected to land on the recovery ship about nine minutes after launch.

They now plan to dock with ISS at 11 am (eastern) on November 16th.

Russian spacewalk to inspect leak in Zvezda

8:13 am

The Russian spacewalk to inspect the outside location of the air leak in the Zvezda module on ISS has now been scheduled for November 18, 2020, and NASA will be providing a live stream.

Live coverage of the Russian spacewalk will begin at 8:30 a.m. EST on NASA Television and the agency’s website. The spacewalk is expected to begin about 9:30 a.m.

Ryzhikov, designated extravehicular crew member 1 (EV1), will wear a Russian Orlan spacesuit with red stripes, and Kud-Sverchkov will wear a spacesuit with blue stripes as extravehicular crew member 2 (EV2). This will be the 47th Russian spacewalk for assembly and maintenance of the station.

During the spacewalk, Ryzhikov and Kud-Sverchkov will first conduct leak inspections outside the hatch, as this will be the first spacewalk using the Poisk module for its purpose as an airlock. Next, they will relocate an antenna from another module, the Pirs docking compartment, to Poisk, the first in a series of tasks over the course of several spacewalks that will prepare Pirs for decommissioning, undocking, and disposal. The Earth-facing Pirs will be replaced by the new Russian Multipurpose Laboratory Module, named “Nauka,” Russian for “science,” which is being prepared for launch at the Baikonur Cosmodrome in Kazakhstan.

What they find could have a significant impact on the future of the space station.

NASA officially approves operational Dragon manned missions

7:03 am

Capitalism in space: NASA yesterday officially certified SpaceX’s Dragon capsule for future operational manned missions to ISS.

NASA officials gave approval Tuesday for SpaceX to begin regular crew rotation flights to the International Space Station with the launch of four astronauts set for Saturday from the Kennedy Space Center in Florida, signaling a transition from development to operations for the human-rated Dragon spacecraft.

Mission managers completed a two-day Flight Readiness Review Tuesday and issued a preliminary go-ahead for the launch of SpaceX’s Crew Dragon “Resilience” spacecraft Saturday at 7:49 p.m. EST (0049 GMT Sunday) with NASA commander Mike Hopkins, pilot Victor Glover, and mission specialists Shannon Walker and Soichi Noguchi, a veteran Japanese space flier.

The decision means that SpaceX will now be rotating crews for NASA at ISS every six months. It will also be reusing both the first stages and the capsules. Endeavour, the capsule used on the demo flight earlier this year, will be reused in the spring. Resilience, the capsule scheduled for launch on November 14th, will be reused next fall.

Since SpaceX also has a commercial manned flight planned for next fall, that will probably require a third capsule. With those three capsules they will have at least for the next few years a fleet will cover all their initial needs. Don’t be surprised if however the introduce an upgraded capsule or two along the way, based on what they learn on these initial flights.

The article had one other piece of new news concerning Boeing’s Starliner capsule. The second unmanned demo flight has now officially been delayed into the first quarter of next year, rather than late this year.

Russians aim for Dec for fixing ISS leak permanently

8:23 am

The Russians announced yesterday that they plan the full and permanent repair of the small inch-long crack leaking air on ISS to occur in December, after required material is shipped to the station.

According to the official, the crack was the width of a hair and located in a hard-to-reach spot of Zvezda’s shell.

Solovyov did not specify the spacecraft that will deliver the sealing materials to the ISS, but the only one scheduled to fly in December is Cargo Dragon, a reusable freight spaceship of US private company SpaceX. The soonest flight of a Russian cargo spacecraft — Progress MS-16 — has been postponed until December 2021.

They also plan a spacewalk in the next two weeks to inspect the exterior of the Zvezda module where the crack is located.

I have yet to see an image of the crack itself. Why none has been made easily available is somewhat puzzling.

Russian astronaut: Crack on ISS could be from “external impact”

10:48 am

Russian astronaut, Sergei Ryzhikov, today noted that to him the 1-inch crack causing the leak on ISS appeared to have been caused by an “external impact.”

Speaking with Flight Director of the Russian segment of the ISS Vladimir Solovyov, Russian cosmonaut Sergei Ryzhikov said: “If you take a closer look at the picture, there are changes of color in the middle of the crack.”

“We suspect an external impact,” Ryzhikov said adding that the place of the suspected impact should be examined during the crew’s next spacewalk, which is scheduled for November 18.

This conclusion is different than that expressed yesterday by another Russian astronaut, who suggested the crack was from age and wear and tear of the twenty-year-old Zvezda module.

Either way, an inspection of the exterior point of the crack is essential in order to permanently seal it, and that inspection will tell us one way or the other the cause of the crack.

Russian astronaut: ISS crack could be result of Zvezda module’s age

7:31 am

A Russian astronaut just returned from ISS admitted during a press conference that the recently located crack on the 20-year-old Zvezda module that was the source of the long-term slow leak could be the result of the module’s age.

“Twenty years are actually an absolute record for all space stations now. And we see now that something is changing and something requires greater [attention]. Again, if we go back to the leak, the hull is already beginning to give cracks and scratches somewhere, that is, we see the limits [of the ISS structure’s service life],” [cosmonaut Ivan Vagner] said.

The crack has been sealed temporarily, with a more permanent seal put in place after the nearby docking port is cleared and the hatches closed and out of the way.

If Russian astronauts are noticing wear and tear in Zvezda that is bad enough to cause “cracks”, this raises some very serious issues for ISS’s future, as replacing that module on ISS will be complicated and expensive, and at this point no one has even begun planning such an replacement.

ISS crew returns safely to Earth in Soyuz

9:22 am

After a six month mission on ISS, three astronauts have safely landed on Earth in their Soyuz capsule.

Cassidy, Ivanishin and Vagner spent 196 days in orbit, having arrived at the station on April 9. They left behind NASA’s Kate Rubins and Roscosmos’ Sergey Ryzhikov and Sergey Kud-Sverchkov, who arrived at the orbiting outpost a week ago for a six-month stay.

Cassidy, returning from his third space mission, has now spent a total of 378 days in space, the fifth highest among U.S. astronauts.

While serving as the station’s commander, Cassidy welcomed SpaceX Demo-2 crew Robert Behnken and Douglas Hurley, the first NASA astronauts to launch to the space station on an American spacecraft from American soil since the retirement of the space shuttle fleet in 2011.

Cassidy and Behnken completed four spacewalks for a total of 23 hours and 37 minutes, becoming two of only four U.S. astronauts to complete 10 spacewalks.

The three astronauts still on board ISS now await the arrival of four astronauts on SpaceX’s Resilience capsule, scheduled for launch in early to mid-November. This will rise the crew on ISS to seven, which I think is the highest since the retirement of the shuttle in 2011.
