Russia reports ‘non-standard’ air leak on Space Station

Russia said Tuesday that astronauts had found an air leak in its section of the International Space Station, with a senior space official calling the air loss beyond expected levels.

The crew on the ISS — Russian cosmonauts Anatoly Ivanishin and Ivan Vagner and NASA astronaut Christopher Cassidy — have been searching for the air leak since August, first checking the US segment.

Russia’s space agency, Roscosmos, said in a statement that after analysis and a search for the leak “it was established that the spot is located in the Zvezda (star) service module, which contains scientific equipment.”

It said a search was now underfoot to pinpoint the exact location, saying the situation “is not dangerous for the life and health of the ISS crew and does not prevent the ISS continuing manned flight.”

“It’s not critical in the near future,” said Sergei Krikalyov, the executive director of Russia’s manned space programs, in a televised comment.

He said the ISS always has slight air loss due to the air purifying system.

“These leaks are predictable. What’s happening now is more than the standard leakage and naturally if it lasts a long time, it will require supplies of extra air to the station,” he said.

He said the crew were now resting but hoped to find the precise spot and fix the leak on Wednesday.

“That’s not for sure,” he added, saying there was quite a large area to search.

“We have time. The leak exists of course. It’s not good that it’s there, but it’s not critical,” he said.

NASA said that the leak had appeared to grow in size overnight Monday to Tuesday and the crew were awakened by flight controllers to carry out a search.

It was later found that a temperature change had made the leak seem to grow, while the rate of air escaping was “unchanged,” the US space agency said.

Previously, astronauts had searched for the source of the leak in the US segment of the station using an ultrasound detector.

The incident comes after astronauts in 2018 found a hole in the wall of a Russian-made Soyuz space capsule docked onto the ISS.

The cause of the hole has not yet been made public.Three new crew members, Russians Sergei Ryzhikov and Sergei Kud-Sverchkov and NASA astronaut Kate Rubins, are set to arrive in a Russian Soyuz spacecraft due to launch October 14.  Source: https://www.daily-bangladesh.com/

NASA to send a new toilet to Space Station

The US space agency NASA is set to test a new zero-gravity toilet to the International Space Station (ISS) before its probable use in a future mission to the Moon.

The $23m (195 crores BDT) toilet, which sucks waste from the body, will be sent to the ISS on a cargo ship.

According to NASA, the toilet's "vacuum system" was designed for the comfort of female astronauts, unlike previous models.

The toilet was supposed to be sent to the space station from Virginia by the rocket on Thursday afternoon. But three minutes before the launch, the mission was aborted due to a technical error. If the engineers can fix the errors, they will try again.

According to NASA, the Titanium Space Toilet will help in missions to more remote areas. The vacuum system is being used here to discharge body wastes in the zero gravity region.

The toilet uses a vacuum system to suck waste away from the body in a zero-gravity environment. For privacy, the toilet is located inside a cubicle - just like in a public bathroom on Earth.

It weighs 45kg (100lbs) and standing 28in (71cm) tall, the toilet is 65% smaller and 40% lighter than the one currently in use.

NASA project manager Melissa McKinley said the Universal Waste Management System (UWMS) toilet has been designed for a long time. The commode seat and urine funnel are more refined than before. Women astronauts will feel more comfortable.

In a video posted to Twitter, Nasa astronaut Jessica Meir described the toilet as a "vacuum system".

"So imagine you have a vacuum cleaner and you're sucking things down. You turn on a big fan, so that's pulling everything down inside the toilet," she said.She added that this toilet will process and recycle urine as drinking water for astronauts in a special way. Source:https://www.daily-bangladesh.com:

Three-man US-Russian crew returns to Earth from ISS

An American astronaut and two Russian cosmonauts touched down on the Kazakhstan steppe on Thursday, completing a 196-day mission that began with the first launch under lockdown conditions.

NASA astronaut Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner landed around 150 kilometres (90 miles) southeast of the Kazakh city of Zhezkazgan at 0254 GMT, footage broadcast by the Russian space agency Roscosmos showed.

A NASA commentator citing communications from crews on the ground at the landing site said that the Soyuz descent module had landed in a vertical position and that the crew were working on getting the trio out of the craft.

The three-man crew had blasted off minus the unusual fanfare in April with around half the world's population living under national lockdowns imposed to contain the spread of the coronavirus.

The mission coincided with the arrival at the space station in May of the first astronauts to blast off from US soil for almost a decade.

The mission carried out by tycoon Elon Musk's SpaceX company as part of NASA's commercial Commercial Crew Program has helped fuel talk of a new "space race" between a number of countries.

Prior to returning from his third mission in space, former US Navy SEAL Cassidy, 50, tweeted a picture of blood samples that astronauts have to submit at various points in their mission, including just before undocking.

"What is the price of a return ride back to Earth?....8 tubes of blood!! The 7 shown in this picture were taken in the morning to be placed in our deep freezer, and the 8th will be drawn just prior to undock for ground processing soon after landing," Cassidy wrote.

First-time-flyer Vagner was a rare Roscosmos presence on the micro-blogging platform, where most NASA astronauts have a profile.

"Mama, I'm coming home," the 35-year-old tweeted on Wednesday.

Ivanishin is wrapping up his third mission, after NASA's Kathleen Rubins, with whom he launched to the ISS in 2016, arrived for a second stint aboard the station last week along with Sergey Ryzhikov and Sergey Kud-Sverchkov of Roscosmos.

The ISS, has been a rare example of cooperation between Moscow and Washington.Next month will mark the 20th anniversary of the orbital lab being permanently occupied by humans, but the station is expected to be decommissioned in the next decade due to structural fatigue. Source: https://www.daily-bangladesh.com/

Nokia, NASA to install 4G on the Moon

Finnish multinational telecommunications, information technology, and consumer electronics company Nokia announced its expansion into a new market on Monday, winning a deal to install the first cellular network on the Moon.

The Finnish equipment manufacturer said it was selected by NASA to deploy an “ultra-compact, low-power, space-hardened” wireless 4G network on the lunar surface, as part of the US space agency’s plan to establish a long-term human presence on the Moon by 2030, according to a report by AFP.

The $14.1 million contracts, awarded to Nokia’s US subsidiary, is part of NASA’s Artemis program which aims to send the first woman, and next man, to the moon by 2024.

The astronauts will begin carrying out detailed experiments and explorations which the agency hopes will help it develop its first human mission to Mars.

Nokia’s network equipment will be installed remotely on the Moon’s surface using a lunar hopper built by Intuitive Machines in late 2022, Nokia said.

“The network will self-configure upon deployment,” Nokia said in a statement, adding that the wireless technology will allow for “vital command and control functions, remote control of lunar rovers, real-time navigation and streaming of high definition video.”

The 4G equipment can be updated to a super-fast 5G network in the future, Nokia said.

In all, NASA announced last week it would distribute $370 million to 14 companies to supply “Tipping Point” technologies for its mission, which include robotics and new methods of harvesting the resources required for living on the moon, such as oxygen and energy sources.

Among them, Elon Musk’s SpaceX received $53.2 million for a demonstration of the transferring of ten metric tons of liquid oxygen between tanks on a starship vehicle, NASA said.Source: AFP Source: https://www.daily-bangladesh.com

SpaceX Crew Dragon “Resilience” docks with ISS

A SpaceX Crew Dragon carrying four astronauts docked with the International Space Station Monday, the first of what NASA hopes will be many routine missions ending US reliance on Russian rockets.

“Dragon SpaceX, soft capture confirmed,” said an announcer as the capsule completed its 27.5 hour journey at 11:01 pm (0401 GMT Tuesday), with the second part of the procedure, “hard capture,” occurring a few minutes later.

The spacecraft, named “Resilience,” docked autonomously with the space station some 260 miles (400 kilometers) above the Midwestern US state of Ohio.

The crew is comprised of three Americans — Michael Hopkins, Victor Glover and Shannon Walker — and Japan’s Soichi Noguchi.

Earlier, mission commander Hopkins gave pilot Glover his “gold pin,” a NASA tradition when an astronaut first crosses the 100-kilometer Karman line marking the official boundary of space.

Glover is the first Black astronaut to make an extended stay at the ISS, while Noguchi is the first non-American to fly to orbit on a private spaceship.

The crew joins two Russians and one American aboard the station, and will stay for six months.

Along the way, there was a problem with the cabin temperature control system, but it was quickly solved.

SpaceX briefly transmitted live images from inside the capsule showing the astronauts in their seats, something neither the Russians nor the Americans had done before.

US President-elect Joe Biden hailed the launch on Twitter as a “testament to the power of science and what we can accomplish by harnessing our innovation, ingenuity, and determination,” while President Donald Trump called it “great.”

Vice President Mike Pence, who attended the launch with his wife Karen, called it a “new era in human space exploration in America.”

The Crew Dragon capsule earlier this week became the first spacecraft to be certified by NASA since the Space Shuttle nearly 40 years ago. Its launch vehicle is a reusable SpaceX Falcon 9 rocket.

At the end of its missions, the Crew Dragon deploys parachutes and then splashes down in water, just as in the Apollo era.

SpaceX is scheduled to launch two more crewed flights for NASA in 2021, including one in the spring, and four cargo refueling missions over the next 15 months.

NASA turned to SpaceX and Boeing after shuttering the checkered Space Shuttle program in 2011, which failed in its main objectives of making space travel affordable and safe.

The agency will have spent more than $8 billion on the Commercial Crew program by 2024, with the hope that the private sector can take care of NASA’s needs in “low Earth orbit” so it is freed up to focus on return missions to the Moon and then on to Mars.

SpaceX, founded by Elon Musk in 2002, leapfrogged its much older rival Boeing, whose program floundered after a failed test of its uncrewed Starliner last year.

– Russians unimpressed –

But SpaceX’s success won’t mean the US will stop hitching rides with Russia altogether, said NASA administrator Jim Bridenstine. The goal is to have an “exchange of seats” between American astronauts and Russian cosmonauts.

Bridenstine also explained it was necessary in case either program was down for a period of time.

The reality, however, is that space ties between the US and Russia — one of the few bright spots in their bilateral relations — have frayed in recent years.

Russia has said it won’t be a partner in the Artemis program to return to the Moon in 2024, claiming the NASA-led mission is too US-centric.

Dmitry Rogozin, the head of Russia’s space agency, has also repeatedly mocked SpaceX’s technology, telling a state news agency he was unimpressed with the Crew Dragon’s “rather rough” water landing and saying his agency was developing a methane rocket that will be reusable 100 times. But the fact that a national space agency feels moved to compare itself to a company arguably validates NASA’s public-private strategy.

SpaceX’s emergence has also deprived Roscosmos of a valuable income stream.

The cost of round-trips on Russian rockets had been rising and stood at around $85 million per astronaut, according to estimates last year.

– Biden incoming –

Presidential transitions are always a difficult time for NASA, and the ascension of Joe Biden in January is expected to be no different.

The agency has yet to receive from Congress the tens of billions of dollars needed to finalize the Artemis program.

Bridenstine has announced that he will step down, to let the new president set his own goals for space exploration.

So far, Biden has not commented on the 2024 timeline.Democratic party documents say they support NASA’s Moon and Mars aspirations, but also emphasize elevating the agency’s Earth sciences division to better understand how climate change is affecting our planet. Source: https://www.daily-bangladesh.com/
