Russian cosmonauts face no threat after air leak at orbital outpost – TASS

Published

 on


MOSCOW, August 20. /TASS/. Russian cosmonauts Anatoly Ivanishin and Ivan Vagner face no threat aboard the International Space Station (ISS) following an air leak at the orbital outpost, the press office of Russia’s State Space Corporation Roscosmos told TASS on Thursday.

A source earlier told TASS that sensors in the Russian segment of the ISS registered an air leak at the space station.

“There is no danger for the crew and the station,” Roscosmos said.

The International Space Station (ISS) crew will move to the Zvezda Service Module for three days, Roscosmos informed TASS. “According to the Lead Operational Control Team for ISS Russian Segment, on Friday the crewmembers will move to the Zvezda module to set up pressure control in the US segment,” the agency said.

Roscosmos clarified that the procedure “is outlined in the board documentation and is a joint decision by the operational control teams of the US and the Russian segments of the International Space Station.”

A source familiar with the situation told TASS that the ISS Russian-US crew was working to localize the air leak. As the source specified, the specialists are planning to sequentially seal off the station’s modules to determine where the pressure was falling.

As the source said, “the air leak was registered by the sensors of the station’s Russian segment for measuring the content of nitrogen, oxygen and carbon dioxide in the station’s atmosphere.”

Last time, an air leak occurred at the ISS on August 30, 2018 when a drop in pressure was detected at the space station. It turned out that the pressure plunge had been caused by an air leak after the Soyuz spacecraft docked to the station, coming from a hole in the spacecraft’s habitation module. A few days later, experts on Earth concluded that the hole had been drilled from inside the Soyuz.

Air leaking from International Space Station but no danger to crew: Roscosmos agency – Reuters Canada

MOSCOW (Reuters) – The International Space Station is leaking air in above-normal volumes, but the leak presents no danger to the Russian-American crew, the Russian space agency Roscosmos said on Tuesday.

The leak has been localised to one section of a service module and the crew, made up of U.S. astronaut Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner, plan to eliminate it in the coming days, Russia’s RIA news agency quoted Roscosmos executive director Sergei Krikalev as saying.

Roscosmos said additional air may be delivered to the station.

Rare blue moon will bring a Halloween 2020 treat to the skies – CNET

Another highly unusual event is headed our way in this bizarre year. The 2020 Halloween full moon will be visible to the entire world, rather than just parts of it, for the first time since World War II, astronomy educator and former planetarium director Jeffrey Hunt says. 

“When I was teaching, my high school students thought a full moon occurred every Halloween,” Hunt told me. Not quite, though pop culture decorations sure make it seem that way. The last Halloween full moon visible around the globe came in 1944, he said. He’s written about the event on his web site, When the Curves Line Up. There was a Halloween full moon for some locations in 1955, but that didn’t include western North America and the western Pacific, Hunt says.

While this year’s Halloween full moon will be visible in all parts of the globe, that doesn’t mean every single citizen will have a view. Residents across both North America and South America will see it, as will India, all of Europe and much of Asia. But while Western Australians will see it, those in the central and eastern parts of the country will not. 

Know time zones well? “Every time zone has it except those east of (GMT) +8 time zones if they have daylight time, or (GMT) +9 with no daylight time,” Hunt says.

Want to see the Halloween full moon? It’s so bright at the full phase it doesn’t matter if you’re in a crowded city or out on the farm. And you don’t need pricey equipment.

“Walk outside, and take a look,” Hunt says. 

Don’t be surprised, though, if you snap a Halloween moon shot with your phone and the photo doesn’t match what you saw.

“When the moon is photographed with a smartphone the results can be disappointing,” Hunt admits. “A telephoto attachment will help make the moon larger.  Be sure to check that the adapter fits on your make and model.  Also don’t overexpose the moon. Adjust the camera’s brightness so that features are visible and not blotted out by the moon’s brightness.” 

If you’re determined to get a good shot, Oct. 1 brings a full moon, so there’s time to practice. Because that makes two full moons in the same month, the Halloween full moon could also be known as a “blue moon.”

If you’re too busy watching horror movies (or doing whatever the coronavirus equivalent of trick-or-treating is), you’ll have to wait until 2039 for another global full moon.

“Of course, full moons occur in October during the intervening years, just not on Halloween,” Hunt says. And a Halloween full moon may appear in your region before then. It just won’t be seen around the world.

‘Earthgrazer’ meteor filmed skimming Earth’s atmosphere and bouncing into space – Yahoo Canada Sports

The space rock whizzed through the night sky above Northern Germany and the Netherlands in the early hours of 22 September. 

A meteoroid is typically a fragment of a comet or asteroid that becomes a meteor (a bright light streaking through the sky) when it enters the atmosphere.

Most of them disintegrate, possibly with pieces reaching the ground as meteorites. 

Earthgrazers are a bit luckier, and don’t burn up, but bounce back out, only grazing the edges of our planet’s protective gassy shield.

Earthgrazers don’t happen very often, just a handful of times per year.

It was spotted by cameras in the Global Meteor Network, a project which aims to cover the globe with meteor cameras and provide the public with real time alerts, building a picture of the meteoroid environment around Earth.

“The network is basically a decentralised scientific instrument, made up of amateur astronomers and citizen scientists around the planet each with their own camera systems” explains Denis Vida, who founded it.

“We make all data such as meteoroid trajectories and orbits available to the public and scientific community, with the goal of observing rare meteor shower outbursts and increasing the number of observed meteorite falls and helping to understand delivery mechanisms of meteorites to Earth”.

Tens of thousands of meteorites have been found on Earth, yet, of these only about 40 can be traced back to a parent asteroid or asteroidal source.

By better understanding these small bodies we are able to build up a more complete image of the Solar System, including potentially dangerous asteroids, meteor shower outbursts which could endanger satellites, as well as the chemistry and origins of our Solar System itself.
