Starliner Launch Delayed Again

If you were hoping to a Boeing Starliner launch to the International Space Station (ISS) today, then you will be disappointed (again). The launch is not expected until Friday May 25 at the earliest.

In a press release, Boeing noted:

The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight. As that work proceeds, NASA’s Commercial Crew Program and the International Space Station Program will take the next few days to review the data and procedures to make a final determination before proceeding to flight countdown.

All we can do is hope and wait. I expect astronauts Suni Williams and Butch Wilmore, who are ready to crew the Starliner, are even more impatient.

Update: The proposed May 25 launch date is now dead as well. NASA has yet to provide a new date for what will be a historic launch if it ever gets underway.

Space Stories: Robot Trains on the Moon, Commercial Space Stations, and Russian Lunar Reactors

Here are some recent stories of interest.

—NDTV: “NASA Announces Plans To Build First Railway System On Moon“

As the National Aeronautics and Space Administration (NASA) readies to return astronauts to the moon, it has announced its plans to build a levitating robot train on the lunar surface. In a blog post, the American space agency provided details about the project called “Flexible Levitation on a Track (FLOAT)”, which aims to provide a “robotic transport system” to support future lunar activities of astronauts visiting the moon. The transport system will be critical to the daily operation of a sustainable lunar base in the 2030s, NASA said in a statement. 

—IEEE Spectrum: “Commercial Space Stations Approach Launch Phase“

A changing of the guard in space stations is on the horizon as private companies work toward providing new opportunities for science, commerce, and tourism in outer space. Blue Origin is one of a number of private-sector actors aiming to harbor commercial activities in low Earth orbit (LEO) as the creaking and leaking International Space Station (ISS) approaches its drawdown. Partners in Blue Origin’s Orbital Reef program, including firms Redwire, Sierra Space, and Boeing, are each reporting progress in their respective components of the program. The collaboration itself may not be on such strong ground. Such endeavors may also end up slowed and controlled by regulation so far absent from many new, commercial areas of space.

—Newsweek: “Russia Reveals New China Nuclear Moon Base Details“

Details about joint plans between Moscow and Beijing to put a lunar nuclear reactor within the next decade have been revealed by the head of Russia’s space agency. In March, Roscosmos announced plans to work with China to build an automated nuclear reactor to power a proposed lunar base that the two countries would operate together within the next decade. To construct the site, Roscosmos director general Yury Borisov said two months ago it was looking at using nuclear-powered rockets to transfer cargo to the moon, but had not yet figured out how to build these spacecraft safely. In an article published Wednesday by state news outlet RIA Novosti, Borisov said that development of the plant was underway and the countries were working on creating experimental and research facilities as part of the project.

Boeing Needs Just One More Day

Today was supposed to be the day that Boeing launched a crewed capsule to the International Space Station (ISS), but things did not go according to plan (again). Two hours before the planned launch a valve issue on the Atlas V rocket’s second stage put everything on hold. A launch as early as tomorrow is still possible if the matter can be resolved.

The two astronauts aboard the Starliner capsule, Suni Williams and Butch Wilmore, will need to come back another day to lead this historic mission. The Starliner will be the second commercial vehicle contracted by NASA to bring and return astronauts from the station. SpaceX has been performing this task since its first successful crewed test flight in 2020.

Boeing needs this win after so many bad stories over the years, and not just the stories associated with the Starliner mission. Serious aircraft woes has put a spotlight on the company. A successful launch will not erase the past, but it would be much needed positive press.

Update: Okay, Boeing will need at least until May 17 to inspect the problem valve and prepare for a new launch. Not a great start, but at least the are still expecting a May launch.

China Returns to the Far Side of the Moon

Last Friday, China launched the Chang’e-6 lunar probe towards the moon with the goal of returning the first lunar soil sample from the far side of the Moon. An earlier mission in 2020, Chang’e-5, successfully returned lunar soil samples from the near side of the Moon for the first time in 44 years. Before that, in 2019, China place a rover on the far side of the Moon via the Chang’e-4 mission.

China is making some bold strides in space with, it might be added, some help from the Europeans. While the US bans any cooperation with the Chinese, France, Italy and Sweden have contributed to the Chang’e-6 mission. For example, Sweden added the Negative Ions at the Lunar Surface (NILS) instrument to the lunar probe.

Maybe one day we can join the Chinese on some of these missions, but that day seems to be far away. That said, we were able to find a way with the Russians, which allowed for the ongoing success of the International Space Station.

Space Quote: Preparing for the Boeing Starliner’s Crewed Mission

“Today was a was a huge day for our Commercial Crew Program…All the (international) partners and then our whole team polled ‘go’ to proceed to the launch on May 6. Not only that, but we (signed) what we call an interim human rating for Starliner for this crewed flight test. … It was a was a huge deal for NASA and our entire team.”

-Statement by Steve Stich, manager of the Commercial Crew Program for NASA, as quoted by CBS News. After numerous delays, the Starliner’s first Crew Flight Test will take place on May 6. If successful, the Starliner will start bringing astronauts to the International Space Station (ISS) in 2025. This will provide NASA with greater redundancy in its ISS resupply runs.
