NASA announced on Wednesday that the troubled Boeing spacecraft will undock from the International Space Station on Friday and attempt to return to Earth without any astronauts on board. The uncrewed liftoff of the Starliner spacecraft is set to take place, assuming the weather is clear at the landing site in New Mexico. The return journey is expected to last about six hours, with the spacecraft scheduled to land at White Sands Spaceport early Saturday morning.

This return flight marks the final phase of a challenging test flight that did not go as planned. The mission was supposed to demonstrate Boeing’s capability to safely transport astronauts to the space station, leading to NASA certification. However, after encountering issues with thrusters and a helium leak from its propulsion system, the mission had to be aborted, leaving astronauts Butch Wilmore and Suni Williams stranded on the space station for an extended period of time.

During a press conference, Steve Stich, NASA’s commercial crew program manager, expressed excitement about Starliner’s return and the lessons learned from this test flight. The spacecraft is set to undock from the space station on Friday evening and land in New Mexico early Saturday morning.

The undocking process will be different without astronauts on board, with precautions taken to protect the space station in case of any malfunctions. After departing from the space station, Starliner will perform a deorbit burn before landing in New Mexico with the help of parachutes and airbags.

A successful return would be significant for Boeing, potentially signaling the safe return of NASA astronauts aboard the spacecraft. However, NASA has requested SpaceX to handle the return flight to minimize risks.

The certification process for Starliner remains uncertain, with NASA and Boeing working together to address issues and improve the spacecraft’s thrusters.

Boeing, along with SpaceX, was awarded a contract under NASA’s Commercial Crew Program to develop spacecraft for transporting astronauts to low Earth orbit. SpaceX’s Crew Dragon spacecraft has been successfully ferrying NASA astronauts to the space station since 2020.

update: A statement was sent to SpaceNews’ Jeff Faust.NASA said the sound had stopped and explained why: “The feedback from the speakers was the result of an audio configuration between the space station and Starliner,” NASA said. “The space station’s audio system is complex, with multiple interconnected spacecraft and modules, and it is common for noise and feedback to occur.” They added that the feedback had no technical impact to the crew or spacecraft operations.

The ill-fated mission to the International Space Station (ISS) aboard Boeing’s Starliner spacecraft has run into trouble once again. The two astronauts, Butch Wilmore and Sunita Williams, who only recently learned they would be staying on the ISS until at least February, began hearing strange noises coming from the Boeing spacecraft over the weekend.

“We’re hearing some strange noises coming from the speakers,” Wilmore told Mission Control in Houston, Texas, on August 31. Recorded by an enthusiast“We don’t know what caused it.”

Mission Control told Wilmore they would investigate the regular pulsating noise. New ScientistBoeing referred requests for comment to NASA, which did not immediately respond.

The Starliner spacecraft delivered Wilmore and Williams to the ISS on June 5, but a thruster failure and helium leak made the planned return trip with passengers deemed too risky.

The noise has puzzled space industry experts and mission control. “It’s very strange,” one person said. Martin Barstow Professor at the University of Leicester in the UK. “I’ve never been on a spacecraft, so I have no idea.”

Social media posts have speculated about the possibility of sonar interference, but say such interference couldn’t come from outside the capsule because sound waves cannot travel in space. Jonathan Aitken “I don’t think it’s a big deal,” said the researcher at the University of Sheffield in the UK. “The bigger question for me is whether it’s a single speaker that’s making the noise, or the whole communications system.”

To investigate the source of the noise, Barstow recommends a thorough inspection of the aircraft. “Find out where there are microphones that might be providing input and isolate them,” he says. “But the sound could also be coming from the audio system electronics.”

Barstow noted that the regular but occasionally erratic nature of the pulse may support the idea that this is a problem with electronic interference.

This hypothesis is Phil Metzger “Electromagnetic interference (EMI) is very common and difficult to eliminate,” said John F. Kennedy, a professor at the University of Central Florida who helped test the ISS intercom system as co-founder of NASA’s Swamp Works research facility at the Kennedy Space Center in Florida. He wrote to X.

Metzger said: New ScientistIn response to an interview request from SpaceX, astronaut John McClellan explained on social media that the interference could be coming from outside the Starliner: “During one test, we heard a noise that we tracked down to its source and found to be coming from a power inverter that is part of the test facility and not the spacecraft,” he wrote. “We believe that the noise on Starliner was due to electromagnetic interference leaking into something like an audio cable with a loose braid at the connector interface.”

What to do about it is another matter: Wilmore’s radio communications with Mission Control suggest that neither he nor Williams were overly concerned about the noise, but were confused as to its source.

There’s no rush to find out what the problem is, since Starliner is scheduled to return to Earth on its own on September 6. “I don’t think it’s significant since there won’t be a crew on board, but anything unusual should always be investigated,” Barstow said. “It might shed some light on an underlying problem.”

Many of the deficiencies identified in the report were not addressed.

Boeing’s response processes for past defects have been ineffective, and the company has not been responsive in taking corrective action for recurring quality control issues,” the company stated.

When asked for comment, a Boeing representative directed NBC News to NASA.

In a written response included in the report, Katherine Corner, deputy administrator for NASA Headquarters’ Exploration Systems Development Mission Directorate, emphasized NASA’s commitment to the highest technical and programmatic standards.

NASA is dedicated to ensuring that its personnel and contractors are qualified, well-trained, and prioritize mission safety,” Corner expressed.

The report suggested various recommendations, such as imposing financial penalties on Boeing for not meeting quality control standards. However, NASA opted not to levy any financial penalties.

The Space Launch System, standing at 322 feet tall, along with the Orion spacecraft, aims to launch astronauts to the moon to establish a base on its surface.

NASA successfully conducted an uncrewed test flight of the Space Launch System rocket and Orion spacecraft in 2022 (Artemis I mission). The following year, four astronauts are scheduled for a crewed flight around the moon (Artemis II mission).

Aside from the first-generation SLS rocket, NASA is also working on a more powerful model capable of carrying more cargo to the moon, led by Boeing as the prime contractor for the enhanced upper stage, known as the Space Launch System Block 1B, with work commencing in 2014.

Originally, an improved rocket system was planned to transport Artemis 2 astronauts into lunar orbit, but this timeline adjustment delayed development and raised costs, as stated by the inspector general.

According to a new report, the Block 1B version of the SLS could potentially cost up to $5.7 billion per launch.

This assessment marks a setback for NASA’s lunar return program, plagued by delays and budget overruns. Over the span of more than a decade, the agency has invested over $42 billion in the Space Launch System and Orion spacecraft.

Last year, NASA’s inspector general estimated each Artemis launch to cost $4.2 billion.

Two NASA astronauts aboard Boeing's Starliner spacecraft successfully docked at the International Space Station on Thursday, despite issues with the spacecraft's thrusters.

NASA confirmed that astronauts Butch Wilmore and Sunita Williams docked with the space station at 1:34 p.m. ET.

“It's good to be connected to the great city of the sky,” Wilmore told mission controllers on the ground.

The docking attempt, originally scheduled for 12:15 p.m. ET, was postponed due to problems with five thrusters on the Starliner.

The hatch between the Starliner capsule and the space station was opened about two hours after docking.

Astronaut Williams was the first to enter the space station, greeted by the ISS crew members already on board.

Wilmore and Williams expressed their gratitude to the teams that worked to get them to the ISS and said they were ready to begin work in orbit.

Their arrival brings the International Space Station to full capacity.

Wilmore and Williams are expected to spend about a week on the ISS before potentially returning to Earth on June 14.

Flight controllers will continue to monitor the capsule's reaction control thrusters for further adjustments.

The Starliner capsule is capable of autonomous docking with the space station.

Boeing has successfully launched its Starliner spacecraft with a crew for the first time on its third attempt, a landmark launch that gives NASA two commercial options for sending astronauts into space: Boeing and SpaceX.

Starliner was launched on an Atlas V rocket from Cape Canaveral, Florida. June 5th, 10:52 AM (local time) After several years of delays, the manned launch has finally come to fruition. Initially, the manned launch was expected to take place by the end of 2017, but the plans fell behind schedule. The mission was finally scheduled to launch in May, but a valve failure forced NASA to abort the mission. The second launch on June 1 was scheduled for Discarded Due to computer problems.

But the third launch just a few days later was successful, with the capsule reaching orbit as planned. Carrying NASA astronauts Butch Wilmore and Suni Williams, they made the 24-hour journey to the International Space Station, where they will stay for about a week to test various systems before returning to Earth aboard the same spacecraft.

The capsule was named Calypso. Reportedly Named after Jacques Cousteau's oceanographic ship, the mission's goal is to verify that Starliner is safe to transport crew to the ISS. If these tests are successful and the two astronauts return safely to Earth aboard Starliner, similar ships could begin annual crewed flights to the space station.

Each Starliner is designed to last up to 10 round trips, carrying up to seven people per flight, though a standard operational flight will likely only carry three or four astronauts.

National Aeronautics and Space Administration (NASA) Two contracts won Ten years ago, there were bids for a shuttle ship to transport crew to the International Space Station. One bid was for Boeing's Starliner, the other was SpaceX's Dragon capsule. Dragon outdid Starliner with its first crewed flight in 2020.

Starliner will be the sixth manned orbital spacecraft launched by the United States, following Mercury, Gemini, Apollo, Space Shuttle and Dragon.
