First picture of hole that occurred on Soyuz in December

Hole in First picture of hole that occurred on Soyuz in December

Russia has now released an image taken using the robot arm on ISS of the leak that occurred on its Soyuz capsule docked to ISS in December.

The picture to the right, cropped and reduced to post here, is that image. This is not the coolant leak hole on the Progress freighter on February 11th, this past weekend. As of now no image of that hole has ever been released.

No interpretation of this hole and the stain around it has as yet been released. However, Russia has now postponed the launch of the next Soyuz capsule from February 19th until early March in order “to give investigators time to rule out similar issues in the upcoming mission.” This Soyuz was to launch unmanned to replace the Soyuz that leaked in December and provide the astronauts that launched on that leaking Soyuz a safe lifeboat that they could come home on.

Meanwhile, all communications with ISS have now been shifted to the private channels, so the public cannot hear them.

All these actions strongly suggest that both the Russians and Americans are now seriously considering the possibility of sabotage or damage to the coolant systems on all Russian spacecraft, before they leave the factory and are launched.

ISS as of February 11, 2023

To clarify the situation, the image to the right shows all the spacecraft presently docked to ISS. Progress 82 is the spacecraft that experienced a leak in its coolant system on February 11th. Soyuz-MS22 experienced a leak in its coolant system in December. At the moment the only safe vehicle for returning the seven astronauts on ISS is Crew-5 Dragon, SpaceX’s Endurance spacecraft. Should a major catastrophe occur requiring an immediate evacuation of the station, the plan right now is for five astronauts to come home on Endurance, and two Russians to come home on the damaged Soyuz. (The thinking is that having only two men on board will prevent too much of a temperature rise during the return to Earth because of the lack of its coolant system.)

With the delay in the launch of the replacement Soyuz lifeboat, this emergency plan will be in place for at least three weeks longer.

SpaceX launches 55 more Starlink satellites

10:20 pm

Using its Falcon 9 rocket, SpaceX tonight successfully launched 55 Starlink satellites into orbit, lifting off from Cape Canaveral.

The first stage successfully completed its 12th flight, landing on a drone ship in the Atlantic. (These 1st stage landings have become so routine that no one at SpaceX even cheered tonight when the stage landed.) The fairing halves completed their 6th and 8th flights respectively. As of posting, the satellites had not yet been deployed.

The 2023 launch race:

10 SpaceX
5 China
2 Russia
1 Rocket Lab
1 Japan

SpaceX completes 33-engine static fire test today of Superheavy prototype #7

10:25 am

Two seconds after ignition
Today’s Superheavy static fire test

SpaceX today successfully completed a 7-second-long static fire test of 31 of 33 Raptor-2 engines at the base Superheavy #7. The test ran for its full duration, and it appears no damage occurred to the launchpad. One engine shut down prior to test, and one shut down prematurely during the test. If this had happened during launch, the booster would still have had enough energy to get Starship to its required velocity to reach orbit.

The company will now have to analyze the test to determine whether it was sufficient to proceed to a March orbital launch. Certainly they will roll the booster back to the assembly building to exchange out the two engines that misfired.

All in all, it appears an orbital test flight of Starship could occur sometime in the next two months, assuming the FAA gets out of the way and issues the launch license.

EARLIER UPDATE:
—————-
Propellant loading is underway, and a rough time estimate for the actual static fire test is now 3 pm (Central).

Musk has now confirmed in a tweet that they are going to proceed to the test. It now appears that they have almost completed propellant loading. It appears they have filled the oxygen tanks, but not the methane tanks, and will probably not fill the methane tanks entirely for the test itself.

Original post:
—————-
No specific schedule has been announced of SpaceX’s attempt today to complete the first full 33-engine static fire test in Boca Chica of its seventh prototype of Superheavy, but a live stream is available from NASAspaceflight.com. I have embedded that live stream below.

The test will validate numerous systems, including the ground systems, the launchpad, the engines, and the systems for igniting all 33 in the proper sequence. Starship prototype #24 is not stacked on top of Superheavy in order to prevent any damage to it in case this test goes ugly. If so, SpaceX already has Superheavy prototype #9 ready to go in the nearby assembly building.

Stacked Starship and Superheavy complete first full wet dress rehearsal countdown

9:06 am

SpaceX yesterday successfully completed a full wet dress rehearsal countdown of its stacked Starship prototype #24 and Superheavy prototype #7, fueling both completely and taking the countdown down to T-0.

On this rehearsal however the Superheavy engines were not fired. From two SpaceX tweets:

Starship completed its first full flight-like wet dress rehearsal at Starbase today. This was the first time an integrated Ship and Booster were fully loaded with more than 10 million pounds of propellant

Today’s test will help verify a full launch countdown sequence, as well as the performance of Starship and the orbital pad for flight-like operations

Next step: Another full wet dress rehearsal countdown that includes a short static fire test of all 33 Superheavy Raptor-2 engines. Once that is done successfully, the company will be ready for that first orbital launch.

Meanwhile, SpaceX awaits its launch license from the FAA. I remain pessimistic that it will be issued on a timely manner, as there are clear signs the Biden administration wants to use its power against Musk, whom it now sees as an enemy.

Astronauts complete Soyuz seat liner installation inside Endurance

9:31 pm

Astronauts today completed the installation of Frank Rubio’s Soyuz seat liner inside the Dragon capsule Endurance so that he can return to Earth should an emergency requiring evacuation occur on ISS.

On Jan. 17, NASA Flight Engineer Josh Cassada, with assistance from NASA Flight Engineer Nicole Mann, worked inside the SpaceX Dragon Endurance crew ship collecting tools and readying the spacecraft for a seat liner move. The seat liner move, completed today, Jan. 18, ensures NASA Flight Engineer Frank Rubio will be able to return to Earth in the unlikely event of an emergency evacuation from the International Space Station. Rubio originally launched to the station with cosmonauts Sergey Prokopyev and Dmitri Petelin aboard the Soyuz MS-22 crew ship on Sept. 21, 2022. The change allows for increased crew protection by reducing the heat load inside the MS-22 spacecraft for Prokopyev and Petelin in case of an emergency return to Earth.

It would be fascinating to get more details about the work that was done to install this Soyuz seat liner in Endurance. Clearly some improvisation was required.

Regardless, this work is only temporary, since Rubio’s seat liner will be shifted again into the replacement Soyuz scheduled to arrive in mid-February.

American astronaut seat liner shifted to Dragon temporarily

2:58 pm

Though NASA has not issued an update, the Soyuz seat liner used by American astronaut Frank Rubio was supposed to be shifted from the leaking Soyuz capsule to Endurance today, just in case that Soyuz needs to be used as a lifeboat. From the January 13th ISS update:

On Thursday, Jan. 12, the International Space Station mission management team polled “go” to move NASA astronaut Frank Rubio’s Soyuz seat liner from the Soyuz MS-22 spacecraft to Dragon Endurance to provide lifeboat capabilities in the event Rubio would need to return to Earth because of an emergency evacuation from the space station. The seat liner move is scheduled to begin Tuesday, Jan. 17, with installation and configuration continuing through most of the day Wednesday, Jan. 18. The change allows for increased crew protection by reducing the heat load inside the MS-22 spacecraft for cosmonauts Prokopyev and Petelin in the event of an emergency return to Earth.

Once the replacement Soyuz MS-23 arrives at the space station on Feb. 22, Rubio’s seat liner will be transferred to the new Soyuz and the seat liners for Prokopyev and Petelin will be moved from MS-22 to MS-23 ahead of their return in the Soyuz.

I expect that once this work is completed tomorrow NASA will issue an update.

SpaceX to build five Starship/Superheavy prototypes in 2023

7:51 am

According to Elon Musk, SpaceX intends to build five Starship/Superheavy prototypes in 2023 for flight testing.

Assuming they can get launch permits, these five rockets should provide the company ample launch testing capability for at least the next two years, especially if it succeeds in landing these units and can consider reusing them in test flights.

At this moment, the launch permits from the federal government appears the main obstacle to getting this heavy lift reusable rocket tested and operational.

Starlink service scheduled for South Korea later this year

8:49 am

SpaceX will begin offering Starlink service in South Korea by the spring of this year.

The article, from a South Korea news outlet, is generally negative about Starlink’s possibilities, mostly because its cost is much higher than that already available with coverage that includes 80% of the country. Nonetheless, Starlink will still be an option to those regions not yet served.

Starlink and National Science Foundation sign deal coordinating spectrum use

9:10 pm

SpaceX and the National Science Foundation (NSF) today signed an agreement coordinating the use of radio spectrum so that Starlink satellites will not interfere with radio astronomy.

The National Science Foundation (NSF) and SpaceX have finalized a radio spectrum coordination agreement to limit interference from the company’s Starlink satellites to radio astronomy assets operating between 10.6 and 10.7 GHz. The agreement, detailed in a statement released by NSF today, ensures that Starlink satellite network plans will meet international radio astronomy protection standards, and protect NSF-funded radio astronomy facilities, including the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO).

This deal was part of a larger negotiation with the entire astronomy community to limit the problems caused to astronomy by the 3,000-plus Starlink satellites presently in orbit. These other actions include

…continuing to work to reduce the optical brightness of their satellites to 7th visual magnitude or fainter by physical design changes, attitude maneuvering, or other ideas to be developed; maintaining orbital elevations at ~700 km or lower; and providing orbital information publicly that astronomers can use for scheduling observations around satellite locations.

This agreement demonstrates again that SpaceX has tried hard to be a good citizen in this matter. It also illustrates once again that ground-based astronomical observations is becoming increasingly impractical. Astronomers have to go to space, and if Starship flies as SpaceX desires, the company will provide them a way to do it.

SpaceX successfully launches 40 OneWeb satellites

10:02 pm

Using its Falcon 9 rocket, SpaceX tonight successfully placed 40 OneWeb satellites into orbit from Cape Canaveral, Florida.

This was only the second launch of this first stage, which landed successfully at Cape Canaveral. The rocket has now deployed all 40 satellites successfully, putting more than 80% of OneWeb’s constellation in orbit.

SpaceX had also planned a Starlink launch from Vandenberg in California tonight, but an hour before launch it was delayed until tomorrow.

At the moment only SpaceX and China have launched any satellites in 2023, and are both tied at 2 launches each.

Musk: SpaceX is now targeting late February/March for 1st orbital launch of Starship

10:01 am

According to a tweet put out by Elon Musk on January 8, 2023, SpaceX is now targeting late February/March for 1st orbital launch of the 24th prototype of Starship and the seventh prototype of Superheavy.

The testing in 2022 has not gone as smoothly as hoped, and is the reason no launch occurred last year:

Super Heavy B7 first left SpaceX’s Starbase factory in March 2022 and has been in a continuous flux of testing, repairs, upgrades, and more testing in the nine months since. The 69-meter-tall (~225 ft), 9-meter-wide (~30 ft) steel rocket was severely damaged at least twice in April and July, requiring weeks of substantial repairs. But neither instance permanently crippled the Starship booster, and Booster 7 testing has been cautious but largely successful since the rocket’s last close call.

Following its return to the OLS [orbital launch site] in early August, Super Heavy B7 has completed six static fire tests of anywhere from one to fourteen of its 33 Raptor engines. It has almost certainly dethroned Falcon Heavy to become the most powerful SpaceX rocket ever tested. And on January 8th, 2023, SpaceX rolled the rocket back to Starbase’s orbital launch site for the seventh time. According to statements made by CEO Elon Musk and a presentation from a NASA official, the last major standalone test between Booster 7 and flight readiness is a full 33-engine static fire. Together, B7’s 33 Raptor 2 engines could produce up to 7600 tons (16.7 million lbf) of thrust at sea level, likely making Starship the most powerful rocket stage in the history of spaceflight.

I had read speculation earlier that it was impossible for SpaceX to do a full 33-engine static fire test because the OLS could not hold the rocket down. That now appears to be incorrect.

Musk’s tweet and proposed schedule should also not be taken with great seriousness. He routinely sets ambitious targets merely to keep the pace fast, even if those targets are not met.

China launches twice today to start its 2023 year

9:42 am

China today launched twice with two different rockets from two different spaceports.

First, a Long March 7 rocket took off from its coast Wenchang spaceport, placing three satellites into orbit. Few details were released about the satellites, other than they were being used for various tests of new technology.

Second, the Chinese pseudo-company Galactic Energy used its military-derived solid fueled Ceres-1 rocket to place five smallsats into orbit from China’s interior Jiuquan spaceport. Once again, little information was released about the satellites.

At this moment China leads SpaceX 2 to 1 in the 2023 launch race. However, there are three more U.S. launches planned for today. First Virgin Orbit hopes to finally launch from Cornwall. You can watch the broadcast here.

Then SpaceX has two launches from opposite coasts within an hour, first launching a batch of Starlink satellites from Vandenberg at 9:15 pm (Pacific), then following with a launch from Kennedy of a batch of OneWeb satellites.

SpaceX raises another $750 million in private investment capital

9:36 am

SpaceX has just completed another round of fund-raising, gaining another $750 million in private investment capital.

This additional money now means that SpaceX has raised about $10 billion in private money, most of which is being used for the development of Starship and Superheavy. When we add the $4 billion SpaceX will get from NASA for Starship, the company now has $14 billion to build this new rocket.
