A Russian space official on Friday blamed a software problem on a newly docked science lab that briefly knocked the International Space Station out of position.
The space station lost control of its orientation for 47 minutes on Thursday, when Russia's Nauka science lab accidentally fired its thrusters a few hours after docking, pushing the orbiting complex from its normal configuration. The station’s position is key for getting power from solar panels and or communications. Communications with ground controllers also blipped out twice for a few minutes.
Vladimir Solovyov, flight director of the space station's Russian segment, blamed the incident on a “short-term software failure.” In a statement released by the Russian space agency Roscosmos on Friday, Solovyov said that because of the failure, a direct command to turn on the lab's engines was mistakenly implemented.
He added that the incident was “quickly countered by the propulsion system” of another Russian component at the station and “at the moment, the station is in its normal orientation” and all its systems “are operating normally.”
NASA said Thursday that the incident moved 45 degrees out of attitude, about one-eighth of a complete circle, but the complex was never spinning, there was no immediate damage or danger to the crew.
The incident caused NASA to postpone a repeat test flight for Boeing’s crew capsule that had been set for Friday afternoon from Florida. It will be Boeing’s second attempt to reach the 250-mile-high (400-kilomter-high) station before putting astronauts on board. Software problems botched the first test.
Russia’s long-delayed 22-ton (20-metric-ton) lab called Nauka arrived earlier Thursday, eight days after it launched from the Russian launch facility in Baikonur, Kazakhstan.
The launch of Nauka, which will provide more room for scientific experiments and space for the crew, had been repeatedly delayed because of technical problems. It was initially scheduled to go up in 2007.
In 2013, experts found contamination in its fuel system, resulting in a long and costly replacement. Other Nauka systems also underwent modernization or repairs.
Stretching 43 feet (13 meters) long, Nauka became the first new compartment for the Russian segment of the outpost since 2010. On Monday, one of the older Russian units, the Pirs spacewalking compartment, undocked from the station to free up room for the new lab.
Nauka will require many maneuvers, including up to 11 spacewalks beginning in early September, to prepare it for operation.
According to Solovyov, on Friday the crew was busy equalizing the pressure in Nauka and planned to open the hatch to the lab later in the day.
The space station is currently operated by NASA astronauts Mark Vande Hei, Shane Kimbrough and Megan McArthur; Oleg Novitsky and Pyotr Dubrov of Russia’s Roscosmos space corporation; Japan Aerospace Exploration Agency astronaut Akihiko Hoshide and European Space Agency astronaut Thomas Pesquet.
In 1998, Russia launched the station’s first compartment, Zarya, which was followed in 2000 by another big piece, Zvezda, and three smaller modules in the following years. The last of them, Rassvet, arrived at the station in 2010.

Each year about 5,000 people are diagnosed with ALS. This is such an important conversation. A disease that can weaken a patient's muscles and impact physical function. However, one research company says that could all change soon. Coya Therapeutics has developed a way to isolate a patient problematic T-cells in order to help ultimately slow the decline of not just ALS, but potentially Alzheimer's and other neurodegenerative diseases as well. Founder and Chief Executive Officer at Coya Therapeutics, Dr. Howard Berman, joined Cheddar to discuss more.
In the fight against climate change, much of the conversation revolves around reducing greenhouse gases like carbon dioxide or methane - and attempting to raise oxygen levels. But there's another gas - hydrogen - that could play a big role in the fight for the climate. Marco Alvera, CEO of Italian energy infrastructure company Snam and author of the book, 'The Hydrogen Revolution,' joined Cheddar Climate to explain the role hydrogen plays in helping achieve a net-zero future.
Americans looking to purchase at-home COVID-19 tests will now have to shell out a bit more money after an agreement expired between the White House and companies to sell the tests at cost. The price of Abbot's BinaxNow test kit from October to December was $14 apiece; on Tuesday, Walmart's website listed the test for $19.88, and Kroger listed the tests for $23.99. Carbon Health Regional Clinical Director Dr. Bayo Curry-Winchell joined Cheddar News' Closing Bell to discuss the impact higher prices will have as the nation experiences another surge in cases.
As millions of kids go back to school, districts across the country are determined to keep class in person, despite a surge in COVID cases. In New York City, Mayor Eric Adams has vowed to keep the nation's largest school system open amid Omicron, citing the disastrous effect of remote learning on students. Oswald Feliz, NYC council member who sits on the health and education committee, joined Cheddar to discuss the city's plan to combat the recent surge and keep kids in school.
Schools across the country are determined to keep class in session, despite the rapidly-spreading Omicron variant. While many parents prefer in-person learning, they also worry whether the current public health guidelines will be enough to protect their kids. Erin Richards, national education reporter for USA Today, joined Cheddar to discuss how are schools are preparing for the surge to avoid another round of remote learning.
With the annual CES convention underway amid COVID, HP unveiled rolled out a number of new products virtually this year, including new gaming PCs and 4K display monitors. But as industries look toward a greener future, HP is working with the climate crisis in mind. James McCall, chief sustainability officer at HP, joined Cheddar's Kristen Scholer to discuss the company's climate goals, which includes reducing its carbon footprint to net-zero by 2040. He admitted that reaching the ambitious goal will be difficult because much of the company's emissions totals come from third parties. "A large part of our footprint is outside of HP's direct control. A lot of it comes either from our incoming supply chain, the materials, our manufacturing process, or about 30 to 40 percent of it comes from our consumer-use base," McCall told Cheddar.
Pfizer and BioNTech are working to develop an mRNA-based shingles vaccine following the success of the COVID-19 shot. This latest collaboration will mark the third time the pharmaceutical companies have worked together on a vaccine.
The potential collapse of the Thwaites glacier in Antarctica has been deemed a potential "doomsday event" — researchers and scientists say its melting and collapse could raise global sea levels by at least two feet, enough to destroy coastal communities around the world. One team of scientists is traveling to the Thwaites glacier to drill below in order to gauge current ocean temperatures and attempt to model possible outcomes. David Holland, professor at NYU and Principal Investigator for the International Thwaites Glacier Collaboration, joins Cheddar Climate to discuss the glacier's potential collapse, his team's research plan, and more.
As winter break wraps up and COVID-19 cases hit record levels, the majority of school districts are returning to in-person classes. While some public schools in large cities have shifted to remote learning for the beginning of the year, the schools that are reopening campuses are determined to avoid the academic, social, and logistical challenges that come with a virtual classroom. Cheddar News is joined by Keith Powers, NYC Council Member, to discuss.
