Boeing Starliner Astronauts Face Potential Space Delay Until 2025

Two NASA astronauts on board Boeing’s Starliner spacecraft may be forced to stay in space until 2025 due to propulsion system issues with the spacecraft.

Summary

  • Two NASA astronauts, Butch Wilmore and Sunita Williams, are currently on the International Space Station (ISS) after their Boeing Starliner spacecraft experienced propulsion system malfunctions.
  • The malfunctions included stalled thrusters, helium leaks, and a faulty propellant valve.
  • Due to the problems, NASA is considering using SpaceX’s Crew Dragon capsule to bring the astronauts home in February 2025.
  • This would require delaying SpaceX’s Crew-9 mission which was originally planned for August 2024.
  • Boeing is still investigating the cause of the Starliner thruster issues.

Boeing Starliner: Stuck in Space Until 2025?

In June 2024, two NASA astronauts, Butch Wilmore and Sunita Williams, embarked on what was supposed to be a routine eight-day mission to the International Space Station (ISS) aboard Boeing’s Starliner capsule. However, their journey has taken an unexpected turn. Due to critical technical issues with the Starliner, including malfunctioning thrusters and helium leaks, their return to Earth has been significantly delayed.

Technical Challenges with the Starliner

The current predicament with the Starliner stems from a series of technical problems encountered shortly after launch. These problems include:

  • Malfunctioning Thrusters: Five of the Starliner’s maneuvering thrusters broke. This made it hard for the spacecraft to move and steer properly.
  • Helium Leaks: Engineers also detected leaks in the spacecraft’s helium valves, which are critical for proper thruster function.

These issues have rendered the Starliner unfit for a safe return journey to Earth at present. Consequently, NASA is exploring alternative options to bring the astronauts home safely.

A Potential Delay Until 2025?

While NASA works to resolve the technical issues with the Starliner, a potential solution involves utilizing SpaceX’s Crew Dragon capsule for a return trip. However, this option wouldn’t be feasible until February 2025, meaning the astronauts could face an extended stay on the ISS.

This extended stay presents logistical challenges, as the ISS is designed to support a specific number of crew members. A longer stay for Wilmore and Williams would necessitate careful planning to ensure adequate supplies and provisions are available throughout their extended stay.

The Impact on Commercial Spaceflight

The problems with the Boeing Starliner are a big setback for commercial spaceflight. This incident shows how crucial it is to have thorough testing and safety rules when developing spacecraft.

The space industry is always changing. Private companies are now more involved in space exploration. The Starliner incident shows how important safety is. Space agencies and private companies must stay committed to safety. They need to work together as they explore new possibilities in human spaceflight.

The situation with the Starliner is complicated. However, it offers many valuable learning opportunities. They need to investigate thoroughly. This means they must look closely at every detail. Their goal is to find the main causes of these technical problems. This is essential to keep future astronauts safe. It will also help ensure the success of future commercial space missions.

NASA Mission at Risk Sunita Williams and Barry Wilmore Must Return in 14 Days

Main Article

NASA’s International Space Station (ISS) is on the brink of congestion as the space agency prepares for its upcoming Crew-9 mission scheduled for August 18. The mission, set to launch from Earth with four astronauts aboard the SpaceX Crew Dragon, faces a potential delay due to the extended stay of astronauts Sunita Williams and Barry “Butch” Wilmore on the ISS. The duo has been stranded since June 6 due to technical issues with their Boeing Starliner spacecraft, which is currently docked at the ISS.

The situation at the ISS has led to concerns about overcrowding, as the station is designed to accommodate only three to six astronauts at a time. The addition of the Crew-9 mission would push the number of occupants beyond this limit, causing potential logistical challenges and safety concerns.

Technical Issues with the Starliner

The Boeing Starliner spacecraft, which was meant to bring Williams and Wilmore back to Earth, has encountered propulsion system problems. The spacecraft’s return has become a priority to free up one of the two docking ports at the ISS.

The Crew-9 Mission

The Crew-9 mission, part of NASA’s collaboration with SpaceX, is crucial for the rotational shift of astronauts aboard the ISS. Scheduled to launch on August 18, the mission includes a six-month stay for its four astronauts, further emphasizing the need to resolve the Starliner issue promptly.

Potential Solutions and Contingency Plans

NASA and Boeing are working diligently to resolve the technical issues with the Starliner. Mark Nappi, who leads the Starliner efforts at Boeing, expressed hope that the technical fixes would be completed soon. The delay has prompted discussions about potential solutions to manage the increased traffic at the ISS.

Impact on the ISS Operations

The potential overcrowding at the ISS could impact daily operations, including scientific experiments, maintenance, and crew activities. The station’s infrastructure is designed to support a specific number of occupants, and exceeding this limit could strain resources.

Conclusion

NASA’s Crew-9 mission and the extended stay of astronauts Sunita Williams and Barry Wilmore on the International Space Station (ISS) highlight how active space exploration is. The ISS sometimes gets crowded. This needs careful planning and quick solutions to technical problems. NASA and the company Boeing are working to bring the Starliner spacecraft back to Earth safely. Their main goal is to make sure all space missions are safe and successful.

NASA Explores Solutions to Return Boeing Starliner Crew Safely

Eight weeks after the Starliner spacecraft launched, NASA is still looking for possible answers to its technical issues—including the possibility of SpaceX lending a hand.

It has now been eight weeks since Boeing’s Starliner spacecraft launched into orbit on an Atlas V rocket, bound for the International Space Station. At the time, NASA officials said the two crew members, Butch Wilmore and Suni Williams, could return to Earth as soon as June 14, just eight days later.

Yes, there had been some problems on Starliner’s ride to the space station that involved helium leaks and failing thrusters. But officials said they were relatively minor and sought to downplay them. “Those are pretty small, really, issues to deal with,” Mark Nappi, vice president and manager of Boeing’s Commercial Crew Program, said during a post-docking news conference. “We’ll figure them out for the next mission. I don’t see these as significant at all.”

But days turned to weeks, and weeks turned to months as NASA and Boeing continued to study the two technical problems. Of these issues, the more pressing concern was the failure of multiple reaction control system thrusters that are essential to steering Starliner during its departure from the space station and setting up a critical engine burn to enter Earth’s atmosphere.

In the last few weeks, ground teams from NASA and Boeing completed testing of a thruster on a test stand at White Sands, New Mexico. Then, last weekend, Boeing and NASA fired the spacecraft’s thrusters in orbit to check their performance while docked at the space station. NASA has said preliminary results from these tests were helpful.

Dragon Becomes a Real Option

One week ago, the last time NASA officials spoke to the media, the agency’s program manager for commercial crew, Steve Stich, would not be drawn into discussing what would happen should NASA conclude that Starliner’s thrusters were not reliable enough for the return journey to Earth.

“Our prime option is to complete the mission,” Stich said one week ago. “There are a lot of good reasons to complete this mission and bring Butch and Suni home on Starliner. Starliner was designed, as a spacecraft, to have the crew in the cockpit.”

For a long time, it seemed almost certain that the astronauts would return to Earth inside Starliner.

However, there has been a lot of recent activity at NASA, Boeing, and SpaceX that suggests that Wilmore and Williams could come home aboard a Crew Dragon spacecraft rather than Starliner. Due to the critical importance of this mission, Ars is sharing what we know as of Thursday afternoon.

One informed source said it was greater than a 50-50 chance that the crew would come back on Dragon. Another source said it was significantly more likely than not they would. To be clear, NASA has not made a final decision. This probably will not happen until at least next week. It is likely that Jim Free, NASA’s associate administrator, will make the call.

Asked if it was now more likely than not that Starliner’s crew would return on Dragon, NASA spokesperson Josh Finch told Ars on Thursday evening,

“NASA is evaluating all options for the return of agency astronauts Butch Wilmore and Suni Williams from the International Space Station as safely as possible. No decisions have been made, and the agency will continue to provide updates on its planning.”

Boeing Starliner Crew NASA Explores Solutions for Safe Return

What follows are some data points that Ars can confidently report based on multiple sources:

  • NASA keeps delaying a decision: A Flight Readiness Review meeting had been scheduled for today, August 1, several days in advance. However, it was canceled. Instead, NASA put out a vague blog update on Thursday stating, “Following the completion of Starliner’s return planning, which is expected to continue into next week, more information will be shared about the agency’s return readiness review preparations and subsequent media briefing.” So maybe the meeting will take place next week.
  • NASA issued a $266,678 task award to SpaceX on July 14 for a “special study for emergency response. NASA said this study was not directly related to Starliner’s problems, but two sources told Ars it really was. Although the study entailed work on flying more than four crew members home on Crew Dragon—a scenario related to Frank Rubio and the Soyuz MS-22 leaks—it also allowed SpaceX to study flying Dragon home with six passengers, a regular crew complement in addition to Wilmore and Williams.
  • SpaceX has been actively working on a scenario in which two or four astronauts launch on board Crew 9: (A normal crew is four) This mission has a nominal launch date of August 18, but it could well be delayed. SpaceX has already identified flight suits that would fit Wilmore and Williams, allowing them to fly home on the Crew-8 spacecraft (presently docked to the space station) or the Crew-9 vehicle. It is unclear how crews would be assigned to the two Dragon return flights. It is possible, if four astronauts launch on Crew 9, that five people could fly home on each of the two Dragons.
  • Two sources told Ars that in meetings this week at NASA field centers, there have been vigorous discussions about whether or not to fly crew home on Starliner: Multiple groups remain “no” on Starliner as of Wednesday. It is unclear how this will be resolved. Some engineers believe that if there are questions about Starliner, then NASA should opt for the safe course—flying on Crew Dragon, which has safely launched 13 times and landed 12 times.

Making Difficult Calls

NASA officials face a difficult decision. Because there is still at least a small risk to flying Starliner in its present condition, the space agency and Boeing have tested the thrusters as thoroughly as possible while the spacecraft is docked to the space station. This testing was intended to “buy down” these risks. But while the data is good, it has not addressed all of NASA’s concerns.

So what will the space agency do? Starliner probably could make it back to Earth safely. But there appears to be some reasonable doubt that Starliner will come back safely. If NASA defers to its fallback plan, flying on Dragon, it may spell the end of the Starliner program. During the development and testing of Starliner, the company has already lost $1.6 billion. Reflying a crew test flight mission, which likely would be necessary should Starliner return autonomously, would cost much more. Boeing might opt to cancel Starliner and leave NASA with just a single provider of crew transportation. That would be painful for both NASA and Boeing.

But the alternative—Starliner not coming home safely with the crew inside—is far, far worse. This is the risk-reward decision that Free, Stich, and other NASA officials ultimately must balance in the coming days.

Conclusion

NASA faces a challenging decision in determining the safest way to return the Starliner crew. With ongoing concerns about Starliner’s thrusters, the reliable alternative of SpaceX’s Crew Dragon is being seriously considered. The ultimate choice will have significant implications for both NASA and Boeing, balancing safety, risk, and the future of the Starliner program.

Main Article

The launch clock isn’t set yet, but the hardware is lined up for what would become the most powerful rocket to ever send humans into space during a moonbound trip the likes of which has not happened in more than 50 years. The biggest piece of the Space Launch System rocket, the 212-foot-long core stage, crept its way into the massive Vehicle Assembly Building on July 24, where work will begin to prepare it for the Artemis II launch set for no earlier than September 2025.

“The clock’s already started,” said John Honeycutt, NASA SLS program manager. “We’ve got a great deal of work to do to get the rocket ready to go fly.”

The core stage sports four RS-25 engines converted by Melbourne-based L3Harris’ Aerojet Rocketdyne from the retired stock of the Space Shuttle Program. Two of the engines have previously flown on a combined 20 shuttle missions, while the other pair are making their debuts. Engine 2047 flew on STS-135, the final launch of the program on Space Shuttle Atlantis in 2011.

Also no stranger to KSC are the casings from the two solid rocket boosters fabricated by Northrop Grumman. They had previously supported space shuttle missions but were regularly fished out of the ocean for refurbishment. Those two boosters sit broken down into five segments each just north of the VAB at the Rotation, Processing, and Surge Facility.

Combined, the core stage and the boosters provide 8.8 million pounds of thrust on liftoff. Their next launch will make the SLS the most powerful rocket to ever send humans into space. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch with Canadian astronaut Jeremy Hansen will ride in the Lockheed Martin-built Orion capsule for what’s planned to be a 10-day trip around the moon.

Doug Hurley, a former NASA astronaut and now an executive with Northrop Grumman who flew on both shuttle missions and the first human spaceflight of SpaceX Crew Dragon, has tried to give the astronauts an idea of what their ride might be like.

“The ride on the booster for 126 seconds, I just said it’s gonna be the most incredible ride of your life. Because really, the acceleration is eye-watering,” Hurley said.

The shuttle rides used boosters made up of four segments versus the five that are stacked for SLS, and with Orion on top of the core stage, it will be more like the Apollo astronauts’ rides on the Saturn V rocket.

“Being on the top of the stack and feeling the steering … can’t wait to hear the story,” he said.

Their goal is to ensure the Orion capsule’s life-support systems work, setting up the Artemis III mission no earlier than September 2026. That mission aims to return humans, including the first woman, to the lunar surface for the first time since the Apollo 17 mission in 1972.

The Artemis II quartet, though, will still travel more than 230,000 miles from Earth, and while not landing on the moon, flying beyond low-Earth orbit is a feat that also has not been accomplished by humans since the final Apollo flight. Glover will become the first Black man to make the trip, Koch the first woman, and Hansen the first Canadian. All 24 of the astronauts who made the trip during nine Apollo missions to the moon between 1968 and 1972 were white American men. Six of those missions sent 12 of those men to the lunar surface.

Delays and Uncertainty

The 2025 launch date for Artemis’ first human spaceflight is nearly a year behind the schedule laid out after the successful launch of Artemis I in November 2022. A roughly two-year gap between the uncrewed debut and the first crewed mission was thought to be enough time to pore over the Artemis I data and work through any issues. But a series of major bumps in the road became evident and one of them has yet to have a final solution revealed by NASA.

That’s the fact that the protective coating on Orion’s heat shield lost a lot more material, some in fist-sized chunks, than what was expected. The ultimate solution for the Orion capsule will be the major domino holding up the process of stacking the SLS to get ready for launch. Managers won’t begin putting it together vertically until they know there will be a spacecraft coming to top it off, but even though this is the second time around, NASA managers expect to face some hurdles.

“There’s always something that happens, you know, something spills on something, some test didn’t work as planned,” said Chris Cianciola, the SLS deputy program manager. “So you triage it all the way. You don’t want to wait ’til you get out to the launch pad to find out you got a problem.”

For now, a completed Orion capsule is expected to be delivered to the VAB by Oct. 31. If NASA signals no delay, then the first placement of the solid rocket boosters in the VAB could begin in September. NASA has built in a one-year lifespan limiter for the solid rocket boosters, a clock that starts ticking the moment the second segment is placed atop the first. That’s expected to happen in the late fall, which would keep Artemis II on its launch target timeline.

Another limiting factor in stacking is getting back to the VAB the mobile launcher on which SLS and Orion will sit. Currently parked at KSC’s Launch Pad 39-B, it has had to go through a series of repairs after the Artemis I launch tore parts of it to shreds.

“These are the largest solid rocket motors on the planet, and when that vehicle lifts off from the mobile launcher, that plume has to go someplace,” said Shawn Quinn, program manager for Exploration Ground Systems (EGS) based at KSC. “As the vehicle gets higher up, that plume spreads out, and it’s a very, very strong force. … Forget about the heat for a moment, but if the person was standing there, they’d be blown out to kingdom come.”

EGS crews also have had to install emergency exit apparatus such as the zipline cages and crew access arm changes so the humans on board can have a chance to survive if something goes wrong on the pad. Quinn said that work is “nearly done” and the mobile launcher should be back at the VAB in time for stacking.

Cost and Criticism

The Artemis program now controls the majority of NASA’s annual budget this year, surpassing the overall science mission budget for the first time as the agency’s top-funded segment. The enacted fiscal 2024 budget comes out to more than $7.6 billion of NASA’s overall $24.875 billion budget. Because the Artemis program involves so many commercial partners, it has a lot of support across Congress, which ultimately approves the budget. So while the science budget request was cut by more than $500 million from the Biden administration request this fiscal year, the Artemis campaign programs were nearly fully funded.

NASA’s Office of the Inspector General has continued to audit the growing costs of the Artemis program, with a 2023 report stating that the Artemis III missions will cost the country $93 billion since its inception in 2012. That’s billions more than envisioned with delays and cost increases plaguing the leadup to Artemis I. The SLS rocket represents 26% of that cost to the tune of $23.8 billion, with a giant chunk spent on the first and second launch hardware.

The audit forecasts future SLS launches to cost more than $2.5 billion each, although NASA has laid out a plan to reduce those costs by half, something the OIG deemed “highly unrealistic” and a threat to its deep-space exploration plans. The audit, though, notes that while SLS is the only viable option now for NASA, competition from SpaceX Starship and Blue Origin’s New Glenn rockets may help level the playing field for NASA’s plans.

“Although the SLS is the only launch vehicle capable of transporting both crew and cargo to the moon in a single mission, its high cost threatens the affordability and sustainability of NASA’s Artemis missions,” the audit stated. “The Agency has taken steps to lower production costs by requiring future SLS rockets to be produced with new, non-refurbished RS-25 engines and solid rocket booster segments. NASA also seeks to reduce per-mission costs to $1.5 billion or less, a goal we find highly unrealistic based on current costs.”

In its response, NASA said it would be up to private companies such as SpaceX and Blue Origin to take up the challenge to provide the vehicles for the next missions to deep space with a target of 2040 for humans to land on Mars. Even for now, a version of Starship is slated to provide the human lunar lander for the Artemis III mission.

But for now, the focus is on getting SLS ready for humans to make the trip around the moon and back. Honeycutt said that while there were still a lot of milestones to hit before launch, he expects to be able to meet them.

“We got to stay focused,” he said. “We don’t have the budget to start over. We got to press forward with what we got and make it work.”

How Time Differs on the Moon: 57 Microseconds Per Earth Day Insight

Key Takeaways

Time on the moon ticks 57 microseconds faster per day than on Earth. This difference could impact navigation and coordination in lunar missions. NASA is tasked with defining a lunar time zone as lunar exploration increases. The disparity in time is due to differences in gravity and the moon’s velocity relative to Earth. Accurate timekeeping is essential for future manned and unmanned lunar missions.

Summary

  • Time on the moon is faster: 57 microseconds faster per Earth day.
  • Lunar missions increasing: NASA plans to return humans to the moon; multiple uncrewed missions already underway.
  • Need for accurate timekeeping: Crucial for navigation, coordination, and scientific experiments.
  • Why time differs: Result of gravitational time dilation and the moon’s relative velocity.
  • NASA’s role: Developing a lunar time zone to standardize timekeeping.
  • Impact on astronauts: Synchronization with Earth time essential for mission success.
  • Scientific importance: Understanding time differences helps in various scientific and technological aspects.
  • Technological challenges: Developing clocks and synchronization methods for lunar use.
  • Future prospects: Improved timekeeping methods could aid in deep space exploration.
  • Collaboration: International efforts required for a unified lunar time system.

Introduction

What time is it on the moon? This question might seem trivial at first glance, but with lunar exploration set to ramp up in the coming decade, defining a lunar time zone has become a critical task. Astronauts and mission controllers must consider that time on the moon ticks ever so slightly faster than it does on Earth—by approximately 57 microseconds per Earth day.

NASA’s Artemis program aims to return humans to the moon for the first time in more than 50 years. Alongside this ambitious plan, multiple uncrewed missions have already made their way to the lunar surface, signaling a new era of lunar exploration. However, the subtle differences in timekeeping between Earth and the moon present a unique challenge that must be addressed to ensure the success of these missions.

Why Time Differs on the Moon

Gravitational Time Dilation

One of the primary reasons for the time difference between the Earth and the moon is gravitational time dilation. According to Einstein’s theory of relativity, time passes at different rates in regions of different gravitational potential. The moon has a weaker gravitational field compared to Earth, meaning that time on the lunar surface passes slightly faster.

Relative Velocity

Another factor contributing to the time difference is the relative velocity of the moon. The moon orbits Earth at an average distance of about 384,400 kilometers (238,855 miles), moving at a speed of roughly 1.022 kilometers per second (0.635 miles per second). This motion causes time on the moon to tick faster compared to a stationary observer on Earth.

Importance of Accurate Timekeeping

Navigation and Coordination

Accurate timekeeping is crucial for the navigation and coordination of lunar missions. With multiple spacecraft operating simultaneously, precise timing ensures that each mission proceeds smoothly without conflicts. Navigation systems rely on synchronized clocks to determine the position and velocity of spacecraft accurately.

Scientific Experiments

Timekeeping also plays a vital role in scientific experiments conducted on the lunar surface. Experiments that measure seismic activity, temperature changes, and other phenomena require precise timing to yield accurate results. Any discrepancies in timekeeping could lead to erroneous data and potentially compromise scientific findings.

Communication with Earth

Maintaining synchronization between lunar and Earth time is essential for effective communication. Mission controllers on Earth need to coordinate with astronauts on the moon, and any time lag could lead to delays or misunderstandings. Standardizing timekeeping practices between Earth and the moon ensures seamless communication and operational efficiency.

NASA’s Role in Defining Lunar Time

Developing a Lunar Time Zone

NASA has been tasked with developing a lunar time zone to standardize timekeeping on the moon. This involves creating a system that accounts for the 57-microsecond daily difference while remaining synchronized with Earth time. The lunar time zone will serve as a reference for all future missions, ensuring consistency and reliability.

Synchronizing Lunar Clocks

One of the challenges in establishing a lunar time zone is developing clocks that can remain synchronized with Earth-based timekeeping systems. These clocks must account for the differences in gravitational potential and relative velocity to maintain accurate time. Advances in atomic clock technology and synchronization methods will be essential for this task.

Impact on Astronauts and Missions

Daily Operations

Astronauts on the moon will need to adjust to the slight difference in timekeeping. While 57 microseconds per day may seem negligible, over the course of a mission, these discrepancies can add up. Ensuring that astronauts’ schedules are synchronized with mission control on Earth is vital for the smooth operation of daily activities.

Mission Planning

Mission planners must consider the time difference when designing schedules and timelines for lunar missions. This includes coordinating launch windows, communication schedules, and scientific experiments. Accurate timekeeping helps in optimizing mission planning and reducing the risk of errors or delays.

Scientific and Technological Significance

Deep Space Exploration

Understanding and addressing time differences on the moon sets a precedent for future deep space exploration. As missions venture farther from Earth, the effects of gravitational time dilation and relative velocity will become more pronounced. Developing robust timekeeping systems for the moon provides a foundation for tackling these challenges in deep space.

Technological Innovations

The need for precise timekeeping on the moon drives technological innovations in clock design and synchronization methods.

Detailed Article

On June 5, 2024, NASA astronauts Butch Wilmore and Suni Williams launched aboard Boeing’s Starliner spacecraft as part of the Crew Flight Test (CFT) mission. The mission, intended to validate the Spacecraft’s performance during a full on-orbit shakedown, saw the Starliner dock with the International Space Station (ISS) the following day. Originally set for a week-long duration, the mission will now extend until June 22, allowing for additional tests and data collection.

The Launch and Docking

The Crew Flight Test for Boeing’s Starliner spacecraft marks a significant milestone in NASA’s Commercial Crew Program. Launching on June 5 from Cape Canaveral, the spacecraft carried two seasoned NASA astronauts: Butch Wilmore and Suni Williams. The mission aimed to demonstrate Starliner’s capabilities and ensure its readiness for future long-term missions.

Upon docking with the ISS on June 6, the Starliner successfully integrated with the station, providing a robust platform for the astronauts to conduct tests and assessments. This docking not only validated the spacecraft’s automated rendezvous and docking systems but also set the stage for an extended stay and additional evaluations.

Delays and Their Implications

First Delay: Extravehicular Activity Preparation

Initially, the mission was scheduled to last about a week. However, on June 9, a delay was announced, pushing the return date to June 18. The primary reason for this delay was to allow ISS residents more time to prepare for an extravehicular activity (EVA) planned for June 13. Unfortunately, this EVA was canceled due to “spacesuit discomfort,” identified shortly before NASA astronauts Tracy Dyson and Matt Dominick were set to exit the station.

Second Delay: Extended Testing

The most recent delay, announced on June 17, extends the mission by an additional four days, moving the return date to June 22. While NASA did not immediately provide a direct reason for this delay, it is believed to offer a unique opportunity for additional testing and validation of Starliner’s systems.

Steve Stich, manager of NASA’s Commercial Crew Program, emphasized the importance of these extended tests:

“We are continuing to understand the capabilities of Starliner to prepare for the long-term goal of having it perform a six-month docked mission at the space station.”
