ISS forced to move to avoid collision with space junk

Published

 on

Astronauts aboard the International Space Station had to carry out an “avoidance manoeuvre” to prevent it from being hit by space junk, NASA has said.

Its trajectory was changed to move it further away from the “unknown piece of space debris”, the US space agency wrote in a blog post on Tuesday.

The three crew members – two Russians and an American – relocated to their Soyuz spacecraft attached to the ISS during the operation, so they could evacuate if necessary.

Experts expected the space junk to pass within “several kilometres” of the ISS, but decided to move it “out of an abundance of caution”.

Russian and US flight controllers worked together to adjust the station’s orbit in an operation which took minutes.

The crew were able to continue with their regular activities after the manoeuvre was complete.

NASA said the crew were not in danger at any time.

“Maneuver Burn complete. The astronauts are coming out of safe haven,” NASA administrator Jim Bridenstine said on Twitter.

It is the third time this year the International Space Station (ISS) has had to manoeuvre to avoid space debris, he said.

He tweeted: “In the last 2 weeks, there have been 3 high concern potential conjunctions. Debris is getting worse!”

Astronomer Jonathon McDowell, at the Harvard-Smithsonian Center for Astrophysics, tweeted the unknown object was a part of a 2018 Japanese rocket which broke into 77 pieces last year.

The ISS is orbiting around 260 miles (420km) above the Earth, travelling at a speed of about 17,130mph (27,568km/h).

At this velocity, even a small object has the ability to cause serious damage to the space station.

NASA has said these kinds of manoeuvres occur on a regular basis, with 25 having occurred between 1999 and 2018.

Ultimate absentee ballot: US astronaut votes from space station – Phys.org

At least she didn’t have to wait in line.

A US astronaut cast her ballot from the International Space Station on Thursday, making her voice heard in the despite being 253 miles (408 kilometers) above the Earth.

“From the International Space Station: I voted today,” crew member Kate Rubins, who began a six-month stint aboard the orbiting station last week, said on US space agency NASA’s Twitter account.

The post featured a photograph of Rubins, her blonde hair floating in the zero-gravity environment, in front of a white enclosure with a paper sign that reads “ISS voting booth.”

Rubins and NASA described the process as a form of absentee voting.

A secure electronic ballot generated by a clerk’s office in Harris County, home of NASA’s Johnson Space Center in Houston, Texas, was sent up via email to the ISS.

Rubins filled out the ballot in the email and it was downlinked and delivered back to the clerk’s office.

She is no stranger to the process: Rubins cast her vote from the ISS during the 2016 election. Congress passed legislation in 1997 that made voting from space possible.

“We consider it an honor to be able to vote from space,” she said in a video before she and two Russian cosmonauts launched from the Russian-operated Baikonur cosmodrome in Kazakhstan on October 14.

“If we can do it from space then I believe folks can do it from the ground too.”

Three other American astronauts were also expected to vote from space but their October 31 trip to the ISS was delayed.

“Even though we have some work ahead of us to determine the outcome of the event — the successful contact, the TAGSAM gas firing, and back-away from Bennu are major accomplishments for the team. I look forward to analyzing the data to determine the mass of sample collected,” Dante Lauretta said in a statement, according to CNN. Lauretta is the principal investigator for the mission and is a professor at the University of Arizona Lunar and Planetary Laboratory.

Space: Astronauts uncovered a leak at the space station ISS with a tea bag – three are back on earth – Pledge Times

Published

Spacemen of the International Space Station ISS have shown ingenuity. The astronauts made use of a tea bag in space. Three of them have now returned to earth.

  • Russia and the USA share the International space station ISS.
  • However, there is one at the station about 400 kilometers above the earth leak.
  • The crew tried to fix the air leak using a Tea bags to detect.

Update from October 22nd, 4:40 p.m. Three of the astronauts who boarded the International Space Station (ISS) with help of a Tea bags one leak have found (see first report), have returned to Earth safely after almost 200 days on the ISS. The US astronaut Chris Cassidy and the Russian cosmonauts Anatoly Ivanishin and Ivan Wagner landed on Thursday in the Kazakh steppe, as photos by the Russian space agency Roskosmos show.

The three spacemen were in April ISS broken up. Because of the Corona pandemic Wagner, Iwanischin and Cassidy had to be in quarantine a good month before the start of their six-month mission. At that time they could not personally say goodbye to their families. It was the third mission on board the ISS for Cassidy and Ivanishin. Wagner, on the other hand, made his first flight to the space station. In a tweet before his return to earth, the 35-year-old wrote: “Mom, I’m coming home.”

First report from October 19, 2020: Space: Leak found at space station ISS – household goods are the solution

Moscow – spaceman the International Space Station have a possible Air leak with help of a Tea bags tracked down. This had flown in weightlessness in the direction of the leak, said cosmonaut Anatoly Ivanishin according to the state agency Tass. “We have several photos and videos of the direction of flight of the teabag.” He reckons with “actually having found the probable leak”. It should start with a duct tape be sealed.

The space travelers have been occupied with the leak in the station about 400 kilometers above the earth for weeks. They had to spend a weekend in the Russian segment in August because they were looking for the hole in another part of the station. According to earlier information from the Russian space agency Roscosmos the leak is “extremely insignificant” and harmless to the astronauts and cosmonauts.

Space station ISS: “Air pressure continues to drop”

“Of the Air pressure continues to fall, but not as quickly, ”said Ivanishin. The crew now wants to better seal the crack and keep an eye on the situation. “Perhaps we should use the more effective patches from our partners,” said the Russian spaceman, referring to his American colleagues.

A short time later that is Oxygen system Elektron-WM failed according to Roscosmos. A spokesman for Roskosmos confirmed, however, that there is no danger for the crew, as the oxygen system in the US segment of the ISS continues to function normally.

ISS: Russian aerospace veteran: “All modules in the Russian segment are worn out”

Currently hold up six spacemen in the ISS. The crew had only last week Reinforcement got after a Soyuz capsule with three spacemen on board after a flight in Record time has docked with the ISS. So far, there have been three space travelers on the ISS, who were also under strict conditions in the spring corona-Pads started. They are supposed to return to earth in October.

It wasn’t until April Oxygen leak found in the ISS, which is more than two decades old. The Russian aerospace veteran Gennadi Padalka told the Ria-Novosti news agency that the station’s Russian equipment had long exceeded its shelf life: “All modules in the Russian segment are worn“Said the cosmonaut who holds the record for the most days spent in space. The equipment was actually only designed for a service life of 15 years. (ck / dpa)

Most recently, an asteroid named “Bennu” was on a dangerous course towards Earth in space. Even a ninth planet in our solar system is said to have been discovered.
