Mission Accomplished: Sunita,Akihiko tackle ISS coolant leak

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.

Tehran, Mar 10: Twenty-seven people have died from methanol poisoning in Iran after rumours that drinking alcohol can help cure the novel coronavirus infection, state news agency IRNA reported on Monday. The outbreak of the virus in Islamic republic is one of the deadliest outside of China, where the disease originated.

Twenty have died in the southwestern province of Khuzestan and seven in the northern region of Alborz after consuming bootleg alcohol, IRNA said.

Drinking alcohol is banned in Iran for everyone except some non-Muslim religious minorities. Local media regularly report on lethal cases of poisoning caused by bootleg liquor.

A spokesman for Jundishapur medical university in Ahvaz, the capital of Khuzestan, said 218 people had been hospitalised there after being poisoned.

The poisonings were caused by "rumours that drinking alcohol can be effective in treating coronavirus," Ali Ehsanpour said.

The deputy prosecutor of Alborz, Mohammad Aghayari, told IRNA the dead had drunk methanol after being "misled by content online, thinking they were fighting coronavirus and curing it." If ingested in large quantities, methanol can cause blindness, liver damage and death.

Iran has been scrambling to contain the spread of the COVID-19 illness which has hit all of the country's 31 provinces, killing 237 people and infecting 7,161.

According to IRNA, 16 out of 69 confirmed cases have died of coronavirus infection in Khuzestan as of Sunday.

Jun 4: Mahatma Gandhi’s statue outside the Indian Embassy in Washington DC was vandalised with graffiti and spray painting by unknown persons allegedly involved in the ongoing protests in the US against the custodial killing of African-American George Floyd.

This has prompted the mission officials to register a complaint with the local law enforcement agencies.

The incident is reported to have taken place on the intervening night of June 2 and 3 in Washington DC.

The Indian embassy has informed the State Department and registered a complaint with local law enforcement agencies, which are now conducting an investigation into the incident.

On Wednesday, a team of officials from Metropolitan Police in consultation with the Diplomatic Security Service and National Park Police visited the site and are conducting inquiries.

Efforts are on to clean up the site at the earliest.

Vandalism of the statue of the apostle of peace comes during the week of nationwide protests against the custodial killing of African-American George Floyd in Minneapolis on May 25.

Several of these protests have turned violent which many times has resulted in damage of some of the most prestigious and sacred American monuments.

In Washington DC, protestors this week burnt a historic church and damaged some of the prime properties and historic places like the national monument and Lincoln Memorial.

One of the few statues of a foreign leader on a federal land in Washington DC, the statue of Mahatma Gandhi was dedicated by the then Prime Minister Atal Bihari Vajpayee, in the presence of the then US president Bill Clinton on September 16, 2000, during his state visit to the US.

In October 1998, the US Congress had authorised the government of India to establish and maintain a memorial “to honour Mahatma Gandhi on Federal land in the District of Columbia."

According to the Indian Embassy website, the sculpture of Mahatma Gandhi is cast in bronze as a statue to a height of 8 feet 8 inches. It shows Gandhi in stride, as a leader and man of action evoking memories of his 1930 protest march against salt-tax, and the many padyatras (long marches) he undertook throughout the length and breadth of the Indian sub-continent.

The statue, the design of which was created by Gautam Pal, is a gift from the Indian Council for Cultural Relations (ICCR). The pedestal for the statue of Mahatma Gandhi is a block of new Imperial Red also known as Ruby Red a block originally weighing 25 tonnes reduced to a size of 9'x7'x3'4". It now weighs 16 tonnes.

Washington, Feb 6: U.S. president Donald Trump drew on staunch Republican support to defeat the gravest threat yet to his three-year-old presidency on Wednesday, winning acquittal in the Senate on impeachment charges of abuse of power and obstruction of Congress.

Only the third U.S. leader ever placed on trial, Trump readily defeated the Democratic-led effort to expel him from office for having illicitly sought help from Ukraine to bolster his 2020 re-election effort.

Trump immediately claimed "victory" while the White House declared it a full "exoneration" for the president -- even as Democrats rejected the acquittal as the "valueless" outcome of an unfair trial.

Despite being confronted with strong evidence, Republicans stayed loyal and mustered a majority of votes to clear the president of both charges -- by 52 to 48 on abuse of power and 53 to 47 on obstruction of Congress -- falling far short of the two-thirds supermajority required for conviction.

"Two thirds of the senators present not having found him guilty of the charges contained therein, it is therefore ordered and adjudged that the said Donald John Trump be, and he is hereby, acquitted," said Supreme Court chief justice John Roberts, who presided over the trial.

The months-long impeachment of the 45th US leader shone a harsh light on America's political divide, with Trump's core support base united behind him in rejecting it as a "hoax."

One Republican, senator Mitt Romney, a longtime Trump foe, risked White House wrath to vote alongside Democrats on the first count, saying Trump was "guilty of an appalling abuse of public trust." He voted not guilty on the second charge.

But the verdict was never truly in question since the House of Representatives formally impeached Trump in December, and has now cleared out a major hurdle for the president to fully plunge into his campaign for re-election in November.

Trump to speak Thursday

Responding to the verdict, Trump announced he would deliver a formal statement Thursday from the White House "to discuss our Country's VICTORY on the Impeachment Hoax!"

Shortly before, the president tweeted a montage depicting a fake cover of Time magazine declaring him president for all eternity.

The White House declared that Trump had obtained "full vindication and exoneration."

But Nancy Pelosi, the House Speaker and top Democrat in Congress, said that by clearing Trump, the Republicans had "normalized lawlessness."

"There can be no acquittal without a trial, and there is no trial without witnesses, documents and evidence," she said.

"Sadly, because of the Republican Senate's betrayal of the Constitution, the president remains an ongoing threat to American democracy, with his insistence that he is above the law and that he can corrupt the elections if he wants to."

Senate minority leader Chuck Schumer said the acquittal was "virtually valueless" since Republicans refused witnesses at his trial.

'Forever impeached'

The Democrats' intense 78-day House investigation faced public doubts and high-pressure stonewalling from the White House.

Concerned about the political risk for the party, Pelosi rejected a call early last year to impeach Trump on evidence compiled by then-special counsel Robert Mueller that he had obstructed the Russia election meddling investigation.

But her concerns melted after new allegations surfaced in August that Trump had pressured Ukraine for help for his 2020 campaign.

Though doubtful from the outset that they would win support from Republicans, an investigation amassed with surprising speed strong evidence to support the allegations.

The evidence showed that from early in 2019, Trump's private lawyer Rudy Giuliani and a close political ally, Ambassador to the European Union Gordon Sondland, were scheming to pressure Kiev to help smear Democrats, including Trump's potential 2020 rival Joe Biden, by opening investigations into them.

"We must say enough -- enough! He has betrayed our national security, and he will do so again," Adam Schiff, who led the House investigation, argued on the Senate floor this week.

"He has compromised our elections, and he will do so again," Schiff said.

'Colossal' mistake

In the trial, Trump's defence was not seen as having undermined the facts compiled by Schiff's probe, and several Republican senators acknowledged he did wrong.

But his lawyers and Senate defenders argued, essentially, that Trump's behaviour was not egregious enough for impeachment and removal.

And, pointing to the December House impeachment vote, starkly along party lines, they painted it as a political effort to "destroy the president" in an election year and insisted voters should be allowed to decide Trump's fate.

Senate majority leader Mitch McConnell said impeachment will benefit Republicans.

"Right now this is a political loser for them. They initiated it. They thought this was a great idea. At least for the short term, it has been a colossal political mistake."
