Houston, November 2: Indian American record-setting NASA astronaut Sunita Williams along with another cosmonaut today troubleshot an ammonia leak in the International Space Station's cooling system, accomplishing the chief objective of their marathon six-hour excursion outside the orbiting lab.

Williams and Japanese space flyer Akihiko Hoshide ventured yesterday outside the space station at 1229 GMT (1759 IST) and just a little more than five hours later, they had reconfigured some coolant lines and deployed a spare radiator, isolating the leak.

"Suni and Aki, heartfelt congratulations to you," NASA astronaut Mike Fincke, who helped walk the astronauts through their tasks from mission control at the agency's Johnson Space Center in Houston, said at 1741 GMT (2311 IST).

"We accomplished just about everything we set out to do today. A big, huge congratulations to you guys on the ground for putting this together," Williams responded.


Each of the space station's eight huge solar panels has its own associated power system, and circulating ammonia helps cool this gear down.

The leak, which NASA and its space station partners first noticed in 2007, has the potential to affect one of these power channels if it's not fixed.

Today's Spacewalk, or extra-vehicular activity (EVA), a crucial step in that process was slated to last about 6 1/2 hours, and it proceeded pretty much on schedule.

By 0128 hrs IST, both astronauts had re-entered the space station through its airlock, and the spacewalk was officially over nine minutes later.

At the start of the spacewalk, Williams — commander of the station's current Expedition 33 — and Hoshide made their way over to the port side of the station's backbone-like truss.

They rejiggered some lines in the affected coolant system and installed a spare radiator.

NASA officials hope this stops the leak, which they suspect may be coming from the old (swapped-out) radiator.

If ammonia continues to escape, the station's operators will eventually have to try something else.

But there likely won't be an urgent need for a new fix, since the spare radiator should provide enough ammonia to keep the coolant system operating until next October or so, officials said.

It should come as no surprise that Williams and Hoshide ticked off their tasks efficiently today, for the two are seasoned space walkers.

In late August and early September, they replaced a vital power unit on the station over the course of two spacewalks, defeating an unexpectedly stubborn stuck bolt in the process.

Today's EVA was the seventh for Williams, the third for Hoshide and the 138th to depart from the station overall.

Washington, Jul 7: The US military "will continue to stand strong” in relationship to a conflict between India and China or anywhere else, a top White House official said on Monday, after the navy deployed two aircraft carriers to the South China Sea to boost its presence in the region.

"The message is clear. We're not going to stand by and let China or anyone else take the reins in terms of being the most powerful, dominant force, whether it's in that region or over here,” White House Chief of Staff Mark Meadows told Fox News.

“And the message is clear. Our military might stands strong and will continue to stand strong, whether it's in relationship to a conflict between India and China or anywhere else,” Meadows said in response to a question.

He was told that India banned Chinese apps because Indian soldiers were killed by Chinese troops last month and asked what's mission of the two aircraft carriers - the Ronald Reagan and the Nimitz - and what's America's mission.

The troops of India and China are locked in an eight-week standoff in several areas in eastern Ladakh including Pangong Tso, Galwan Valley and Gogra Hot Spring. The situation deteriorated last month following the Galwan Valley clashes that left 20 Indian Army personnel dead as the two sides significantly bolstered their deployments in most areas along the LAC.

The Chinese military on Monday began withdrawing troops from the Galwan Valley and Gogra Hot Spring after National Security Advisor Ajit Doval and Chinese Foreign Minister Wang Yi held lengthy talks on Sunday. Doval and Wang are also the special representatives on the India-China boundary talks.

The United States has sent two of its aircraft carriers to the South China Sea. “Our mission is to make sure that the world knows that we still have the preeminent fighting force on the face of the globe,” Meadows said.

President Donald Trump has invested more in the US military, more in not only the hardware, but the men and women who serve so sacrificially each and every day, he said. “He (Trump) continues to do so,” he added.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Appearing on the same Fox News on Monday talk show with host Brian Kilmeade, influential Republican Senator Tom Cotton said that the US aircraft carriers are headed to the South China Sea to thwart off any Chinese misadventure against Taiwan or other countries in the region.

"That's one of the reasons why we have those aircraft carrier groups in the South China Sea. I mean, look what China did in the southwest. It's essentially invaded India over the last few weeks and killed Indian soldiers,” Cotton said.

"No country on China's periphery, right now, is safe from Chinese aggression. All those countries want a close relationship with the United States. We ought to have one,” Cotton said.

From loudspeakers on the roof of a Minnesota mosque, the Islamic call to prayer echoed for the first time ever throughout a Minneapolis neighbourhood late on Thursday as the Muslim community there prepared to begin the holy month of Ramadan.

It echoed again on Friday morning and will continue five times a day during the holy month. 

The simple, short call - known as the adhan - marked an historical moment for Minneapolis and major cities across the United States, community members said. While the adhan is commonly broadcast throughout the Middle East, North Africa and other places, for many Muslims in the US, it is only heard inside mosques or community centres.

"There's definitely a lot of excitement," said Imam Abdisalam Adam, who is on the board of the Dar al-Hijrah mosque, from where the adhan will be broadcast.
"Some people see it as historic," Adam told Al Jazeera. "To the point ... that they're not doing it, able to see it in their lifetime." 

Recited by different representatives from mosques around the city, the call to prayer is expected to reach thousands in the Cedar-Riverside neighbourhood in Minneapolis, according to Jaylani Hussein, the executive director of Minnesota's Council on American-Islamic Relations (CAIR).

While Hussein says the community had discussed broadcasting the call for years, it became even more pressing this year when the coronavirus pandemic forced mosques to shut their doors and residents to stay inside. The coronavirus has infected more than 870,000 people nationwide and killed at least 50,000.
"We wanted to touch those individuals who frequent this mosque and this community," Hussein said. "If we cannot be physically together, at least this echo, this voice, this call to prayer can be an extension of us being together at this difficult time. To give some people some solace."

Ramadan is traditionally a time when Muslims worldwide regularly attend mosques for daily prayers and break their fasts together. But this year, most have been told to pray at home and forgo community iftars in favour of staying safe from the COVID-19 crisis.

Adam, the imam, said while the Muslim community is experience loss this Ramadan, they hope the call to prayer broadcast will create a "semblance of normalcy".

"With the loss of Friday prayers and the regular congregational prayers, we are hoping that this will give a sense of solace and connection to the spiritual needs of community members," he added. 

An avenue to greater investment?

The Cedar-Riverside neighbourhood is a densely populated area of Minneapolis that has historically been an entry point for many immigrants and today is home to large Somali and Oromo communities.

Ramla Bile, a Somali American who lives in a neighbourhood adjacent to Cedar-Riverside, has been active in the community for years. She welcomed the broadcast of the call to prayer, saying it will help people "feel the spirit of Ramadan in a way that is meaningful".

But she also hopes the city of Minneapolis, which provided the noise permit for the broadcast, will make bigger strides to invest in the community in even more tangible ways.

"There's been a lot of need and a lot hurt in the community in light of the COVID-19 pandemic. And then there's the ongoing conversation you've been having," she said, pointing to deep-seated Islamophobia, systemic racism and the need for infrastructure projects like sprinkler systems in high-rise buildings. 

"We need to see greater investments to support the most vulnerable members of our community," Bile said referring to the neighbourhood's elders, undocumented individuals, low-income families and others.

"Right now, we're waiting for a bailout for our micro-businesses who comprise our Somali malls, or a rent freeze for neighbourhood residents," she added.

For CAIR's Hussein and Imam Adam, they hope this Ramadan's call to prayer helps encourage other communities around the US to take similar steps.

"This will hopefully inspire others … to think about what could happen in future Ramadans and beyond," Hussein said.

Adam added that while the virus has devastated communities and upended daily life, it has also shown that "we're in this together".

"It just shows the significance of the global village and how interconnected and interdependent we are as a world community," he said. "I think that there will be a lot of change in our way of life for the better. I hope so."

The new visa regulations requiring international students in the US with an F-1 visa to take at least one in-person course or face the prospect of deportation is likely to "cause uncertainties and difficulties" for some students, the Indian Embassy has said.

"These new modifications at a time when many of the US universities and colleges are yet to announce their plans for the new academic year are likely to cause uncertainties and difficulties for some Indian students wishing to pursue their studies in the US," said a spokesperson of the Indian Embassy.

Responding to media queries, the spokesperson said the Indian government has taken up the matter with concerned US officials.

At the India US Foreign Office Consultations held on July 7, Foreign Secretary Harsh Vardhan Shringla conveyed India's concerns on the matter to Under Secretary of State for Political Affairs David Hale.

According to a recent report of Student and Exchange Visitor Program (SEVP), there were 1,94,556 Indian students enrolled in various academic institutions of the US in January this year. Of these 1,26,132 were males and 68,405 were females.

Noting that partnership in higher education is a key component of the strong people-to-people ties between India and the US, the spokesperson said in the last two decades Indian students in American universities and colleges have been the harbingers of a strong partnership between technology and innovation sectors between the two countries.

The spokesperson hoped that the US authorities would provide adequate flexibility in their visa rule, keeping in mind the extraordinary circumstances created by the COVID-19 pandemic for the Indian students community.

We continue to engage all the stakeholders in the matters, including the US administration officials, Congressional leaders, universities and colleges as well as the Indian students community in the US as we move forward towards the 2020-21 academic year to further strengthen our bilateral partnership in higher education, the spokesperson said.

Announced by the SEVP on July 6, the new rules provide temporary exemptions for nonimmigrant students on F-1 and M-1 visas taking online classes due to the COVID-19 pandemic for the fall semester of the 2020 academic year.

While these modifications do provide some flexibility for US universities and colleges to adopt a hybrid model -- that is a mixture of online and in person classes -- they also restrict international students on F-1 and M-1 visas from taking courses entirely online, the spokesperson said.
