A pair of Russian astronauts went on an EVA on Thursday after the smoke detector rang at part of the International Space Station (ISS).
Astronauts Oleg Novitskiy and Pyotr Dubrov have been adventuring outside the ISS for five hours at 10:51 am EST, preparing to operate the new Nauka nauka.
Duo connected An Ethernet cable and a handrail installed in Nauka docked with the Orbiting Laboratory on July 29.
The alarm sounded on the Zvezda module, which was added to the ISS in 2000. It rang at 4:55 am Moscow time (Wednesday 9:55 ET).
“The smoke detector was activated and the alarm sounded while the automatic battery was being charged at the Zvezda service module in the Russian segment of the International Space Station,” Roscosmos said in a statement.
The incident, declared by NASA as a “space emergency,” is the latest in a series of issues that have spurred safety concerns about the situation in the Russian segment.

Two Russian astronauts performed extravehicular activity on Thursday after the smoke detector rang in part of the International Space Station (ISS).
French astronaut Thomas Pesque quoted NASA’s broadcast as saying that “the smell of burning plastic and electronics” is floating in the US segment of the station.
The Russian crew turned on the filter, and after the air was clean, the astronauts went to sleep, Roscosmos said.
The space agency said the planned EVA would proceed as planned.
“All systems are working fine,” Roscosmos followed the smoke detector.

Novitsky and Dubrov carried out a five-hour mission to integrate Nauka (pictured) with the ISS, including connecting power and Ethernet cables. Nauka experienced her own problems when she first docked with the ISS. The 22-ton module jet thruster misfired hours after docking with the space station.

Nauka experienced her own problems when she first docked with the ISS. The 22-ton module jet thruster misfired hours after docking with the space station.
According to NASA, the incident caused the ISS to deviate from its attitude by 45 degrees, or one-eighth of the perfect circle.
However, the flight director in charge at the time revealed that this was “reported a little wrong”, and the actual number was close to 540 degrees.
This means that when the ISS was rotated and sent, it performed 1.5 backflips and required a 180 degree forward flip to return it to its original position.
The Nauka accident is a recent error, as the Russian segment of the ISS recently experienced some problems and space officials last month warned that old software could lead to “irreparable failures.”
Russia is also threatening to leave the ISS project and build its own space station unless the United States lifts the sanctions imposed on the country.

The Zvezda Service Module, which is part of the Russian segment, has experienced several air leaks, including earlier this year and 2019.
Russia has previously indicated plans to leave the ISS and launch its own orbital station after 2025, citing concerns due to aging hardware.
In July, the entire ISS went out of orbit after the Nauka module thrusters reignited hours after docking.
And in August, Russian astronauts said they had found a new crack in part of the ISS that could worsen over time.
Superficial “cracks” were discovered in the Zarya module, the first part of the ISS launched in 1998. Russia..
The country’s space authorities have warned that the latest incidents on the train station could become more widespread in the coming years, following the discovery of other cracks last year.

“Superficial cracks were found in several places on the Zalya module,” Vladimir Solobyov, chief engineer of rocket and space company Energia, told RIA news agency at the time.
“This is bad and suggests that the cracks will begin to spread over time.”
He didn’t say if the crack caused an air leak.
Last year, the ISS crew searched for an air leak for several weeks and tracked it to a major work area within the Zvezda module in Russia.
NASA emphasized that the leak did not pose an imminent risk to the crew and caused only a slight deviation in the ongoing work schedule.
In August 2018, an astronaut was in a hurry to repair a hole (pictured) that appeared on the outer wall of a Soyuz capsule in an orbiting laboratory. Its origin is a mystery, despite many speculations, and is still a mystery.
The $ 100 billion ISS is located 250 miles above Earth
The International Space Station (ISS) is a $ 100 billion (£ 80 billion) science and technology laboratory that orbits 250 miles (400 km) above Earth.
Since November 2000, astronauts and astronaut replacement crews have been resident.
Studies conducted on the ISS often require one or more anomalous conditions that exist in low earth orbit, such as low gravity and oxygen.
ISS research involves human experimentation, space medicine, life sciences, physical sciences, astronomy, and meteorology.
NASA, a US space agency, spends about $ 3 billion (£ 2.4 billion) annually on space station programs. This is a level of funding approved by the Trump administration and Congress.
The US House of Representatives, which oversees Nasa, has begun to consider whether to extend the program after 2024.
Alternatively, the money can be used to speed up planned human space initiatives for the Moon and Mars.
Solobyov previously said that many of the International Space Station’s equipment is beginning to age and warned that a “avalanche” of broken equipment could occur after 2025.
This is also the year Russia plans to leave the ISS project and possibly launch its own orbital station.
April, Deputy Prime Minister Yuri Borisov He told Russia 1 TV channel: Moscow intended to warn ISS partners about the withdrawal.
He said the station had a long service life and the condition was “a lot is desired.”
It is unclear whether Russia will decide to abandon all work on the ISS altogether.
It will come later NASA Earlier this month, it refuted Russia’s claim that US astronauts had pierced the ISS to force an early return to Earth that they were “struck by a psychological crisis.”
According to a report by Russian state news agency TASS, Roscosmos insiders are unfamiliar with module design and have multiple holes without proper support to ensure accurate drilling in low gravity. Claimed to have been excavated.
They claim that NASA astronaut Serena Auñón-Chancellor punctured the jugular vein because of a blood clot that had to be treated herself, leading to an “acute psychological crisis.”
NASA did not comment on the issue, but explained that the astronauts were highly respected and challenged the allegations.
In August 2018, astronauts were in a hurry to repair a hole in the outer wall of the orbiting laboratory Soyuz capsule.
Its origin is, and still is, a mystery, despite speculation and criticism from all sides.
The latest report is believed to have distracted NASA’s accusations over the arrival of the Russian science module, which Roscosmos is spinning the ISS in July.
