With an eye on Venus and Mars, ISRO attempts mega world record

February 12, 2017

Bengaluru, Feb 12: India will boldly go to Venus for the first time and re-visit the Red Planet very soon. Buried and hidden in the hundreds of pages of the new format electronic budget documents, is the first formal acknowledgement by the government about these two new bold inter-planetary sojourns to Earth's immediate neighbours.

This uplifting news comes ahead of the Indian Space Research Organisation (ISRO) attempting to undertake its mega launch where it will drop off into space not one, two or three but a full load of 104 satellites in space in a single mission.

No other country has ever tried to hit a century in a single mission. The last world record is held by Russia which in 2014 rocketed 37 satellites in a single launch using a modified inter-continental ballistic missile.

If all goes according to plan, on the morning of February 15, ISRO will hurl into space using the Polar Satellite Launch Vehicle (PSLV) three Indian satellites and a 101 small foreign satellites.

India is hoping to better the previous world record by a whopping two-and-a-half times. ISRO, considered the new kid on the block in the multi-billion dollar world launcher market, hopes to set an enviable benchmark for the space fairing nations.

Prime Minister Narendra Modi's love affair with space is quite evident. The government, it seems, is rather pleased with the Indian space agency as Finance Minister Arun Jaitley gave the Department of Space a whopping 23 per cent increase in its budget. Under the space sciences section, the budget mentions provisions "for Mars Orbiter Mission II and Mission to Venus".

The second mission to Mars is tentatively slated for in 2021-2022 timeframe and as per existing plans it may well involve putting a robot on the surface of the Red Planet.

While India's first mission to Mars undertaken in 2013 was a purely Indian mission, the French space agency wants to collaborate in making the Mars rover.

In fact on a visit to India this month, Michael M Watkins, Director of the Jet Propulsion Laboratory of NASA, said they would be keen to at least put a telematics module so NASA's rovers and the Indian satellites are able to talk to each other.

The second Indian mission to Mars is likely to be all about doing good science since the first one had a nationalistic streak on it in trying to beat China to the orbit of Mars which the Mars Orbiter Mission (MOM) did magnificently.

India's maiden mission to Venus, the second planet of the Solar System named after the Roman goddess of love and beauty, is in all probability going to be a modest orbiter mission.

Watkins said a mission to Venus is very-very worthwhile as so little is understood about that planet and NASA would definitely be willing to partner in India's maiden voyage to Venus.

Towards that, NASA and ISRO have already initiated talks this month on trying to jointly undertake studies on using electrical propulsion for powering this mission.

India's original inter-planetary dreamer K Kasturirangan, former chairman of ISRO, says, "India should be part of this global adventure and exploring Venus and Mars is very worthwhile since humans definitely need another habitation beyond Earth."

Closer to home on its 39th launch India's workhorse rocket the PSLV will lift off carrying 1378 kg of robots to be deployed in space.

The first to be let off will be India's high resolution Cartosat-2 series satellite made especially to monitor activities of India's hostile neighbours at a resolution of less than a metre keeping a bird's eye view on both Pakistan and China.

This earth imaging capability is not unusual but the rest of the passengers are unique. There are two small Indian satellites each weighing less than 10 kg that are forerunners of a new class of satellites called ISRO Nano Satellites which the engineers seek to master.

What follows next is a trailblazing performance by the PSLV when at an altitude of over 500 km in space it will release from its womb, 101 co-passengers one each from Israel, Kazakhstan, The Netherlands, Switzerland, the UAE and a whopping 96 from the US. It is only recently American private companies have warmed up to ISRO as India offers cheap and reliable option.

Eighty-eight of the American satellites belong to a San Francisco based start-up company Planet Inc which is sending a swarm of small 4.7 kg each satellite it calls 'Doves'. This constellation will image earth like never before and with a high repeat rate providing satellite imagery at an affordable cost.

This suite of 101 small satellites all together weighing 664 kg will be released in space in a manner akin to a typical school bus which drops of its passengers namely children at their respective bus stops in a sequential manner, avoiding squabbling and elbowing in near zero gravity is not easy.

Ensuring that no collisions take place even is an art that ISRO has mastered from previous launches. In less than 600 seconds all 101 satellites will be released into space each travelling at whopping velocity of over 27,000 km per hour or at 40 times the speed of an average passenger airliner.

Some experts are suggesting that in a bid to earn some money ISRO is actually contributing significantly to the creation of space junk as these small satellites are really not very useful.

But Laura Grego, Senior Scientist, Global Security Program, Union of Concerned Scientists, Cambridge, USA says, "I think that these launches can be done responsibly and provide benefits to all people. Developing a culture of responsible space launch and operations is key as more and more countries become space-faring.

"While the number of countries that can launch satellites independently is still quite small, many dozens of countries own and operate satellites."

Kasturirangan says, "India has the capability putting several satellites in a single launch and demonstrating that capability is certainly not bad as it adds to India's credibility and then later if ISRO deploys this capability of formation flying in a constellation of its own satellites it would be a useful addition to its arsenal."

Bosnia, Jul 12: Bosnians commemorated on Saturday the massacre of about 8,000 Muslim men and boys in Srebrenica, marking the 25th anniversary of killings that shocked the world and have stood out as Europe's only atrocity since World War Two constituting genocide.

Nine newly identified victims were buried at a flower-shaped cemetery near the town, where tall white tombstones mark the graves of 6,643 other victims.

"After 25 years we succeeded in finding his mortal remains, so they can be laid to their final rest," said Fikret Pezic, who buried his father Hasan.

The remains of some 1,000 victims of the massacre in the eastern town during Bosnia's 1992-1995 war are still missing.

Ifeta Hasanovic decided to bury incomplete remains of her husband, saying: "We were aware they cannot be complete after 25 years, at least there are some, I did not want to make any new delays."

World leaders addressed the ceremony by video link, unable to attend because of coronavirus epidemic. Instead of the tens of thousands visitors who typically attend the commemoration each year, only a few thousand came after organisers banned organised visits.

During the Bosnian war, Bosnian Serb forces pushed non-Serbs out of territories they sought for their Serb statelet. Fleeing Muslims took shelter in several eastern towns, including Srebrenica, that were designated as United Nations "safe zones".

On July 11, 1995, the Serb forces commanded by General Ratko Mladic overran Srebrenica, which was protected by lightly armed Dutch peacekeepers.

They sent women and children away and captured and executed the men and boys they found. The bodies were dumped into mass graves and later exhumed by U.N. investigators and used as evidence in war crimes trials of Bosnian Serb leaders.

"We grieve with the families that tirelessly seek justice for the 8,000 innocent lives lost, all these years later," said U.S. Secretary of State Mike Pompeo. Washington brokered Bosnia's peace deal months after the massacre.

Most people at the commemoration were Muslim Bosniaks, reflecting conflicting narratives about the bloodshed - which hinders reconciliation nearly 25 years after the end of war in which about 100,000 people were killed.

The U.N. war crimes tribunal for the former Yugoslavia convicted Mladic and his political chief Radovan Karadzic over Srebrenica genocide but they remained heroes for Serbs, many of whom deny that genocide happened.

On Saturday, the Serbs in the nearby town of Bratunac organised an event marking July 11 as the "Srebrenica Liberation Day".

Sefik Dzaferovic, the Bosniak chairman of Bosnia's tripartite presidency, called for legislation that would ban denial of genocide.

"There can be no trust as long as we witness attacks on the truth, denial of genocide and glorification and celebration of executors," Dzaferovic told the commemoration gathering.

Bengaluru, Mar 6: The Karnataka government has directed school authorities to grant leave to students and staff suffering from cold or fever in the light of renewed coronavirus (COVID -19) fears.

"If any student, teacher of staff is suffering from respiratory infections, they should be granted leave. They should be allowed to come back to school only after confirming from the doctor that they are cured. In case of a student or staff staying at hostels developing any symptoms, they should be kept in a separate room," said the government circular.

Aiming at containing the spread of coronavirus, Sriramulu said, "We have formed 1,680 isolation wards in private hospitals. Chief Minister B.S. Yediyurappa has apprised Prime Minister Narendra Modi and Union Health Minister of the situation."

However, the Health Minister said no positive case has been recorded till now in the state.

"Tests are also being conducting on passengers arriving in Karnataka and all precautionary measures are being taken," said Sriramulu about the 40,000 people thermal screened at the Kempegowda International Airport (KIA) in the city. Major private hospitals in the city have geared up to treat suspected cases.

Five Karnataka districts bordering Kerala -- Dakshina Kannada, Kodagu, Udupi, Chamarajanagar and Mysuru -- continue to be under surveillance after three positive coronavirus cases were reported in Kerala

The deadly virus has killed a total of 2,912 people in mainland China till Saturday, bringing the global death toll to more than 3,000, authorities said on Monday.

The Karnataka Health and Family Welfare Department is observing 461 people under home quarantine even as no positive coronavirus case has been reported from the state, an official said on Thursday.

"We are observing 461 people for Coronavirus symptoms at their residences, however, no positive case has emerged from Karnataka," said state Health Department's Joint Director, Communicable Diseases, Prakash Kumar.

The five people under isolated observation at Rajiv Gandhi Institute of Chest Diseases continue to be so on Thursday as well. As many as 273 samples sent from the state for coronavirus testing reported negative.

In Karnataka, 68,717 passengers have been thermal-screened for the virus until now at Kempegowda International Airport in the city and Mangluru International Airport.

Another 5,103 passengers were also checked for the virus at Karwar and Mangluru seaports.

On Thursday, 16 people completed the mandatory 28-day observation period while a total of 225 people also underwent the same.

Karnataka is screening all international passengers and the state health department met the private sector hospitals to take stock of recent developments.

Madrid, Mar 26: More than three billion people around the world were living under lockdown on Wednesday as governments stepped up their efforts against the coronavirus pandemic which has left more than 20,000 people dead.

As the number of confirmed cases worldwide soared past 450,000, UN Secretary General Antonio Guterres warned that only a concerted global effort could stop the spread of the virus.

In Spain, the number of fatalities surpassed those of China, where the novel coronavirus first emerged three months ago, making it the hardest-hit nation after Italy.

A total of more than 20,800 deaths have now been reported in 182 countries and territories, according to an AFP tally.

Stock markets rebounded after the US Congress moved closer to passing a $2.2 trillion relief package to prop up a teetering US economy.

In Washington, President Donald Trump said New York, the epicenter of the US outbreak with over 30,000 cases, likely has a few "tough weeks" ahead but he would decide soon whether unaffected parts of the country can get back to work.

"We want to get our country going again," Trump said. "I'm not going to do anything rash or hastily.

"By Easter we'll have a recommendation and maybe before Easter," said Trump, who had been touting a strong US economy as he faces an election in November.

UN chief Guterres said the world needs to ban together to stem the pandemic.

"COVID-19 is threatening the whole of humanity -- and the whole of humanity must fight back," Guterres said, launching an appeal for $2 billion to help the world's poor.

"Global action and solidarity are crucial," he said. "Individual country responses are not going to be enough."

India's stay-at-home order for its 1.3 billion people is now the biggest, taking the total number of individuals facing restrictions on their daily lives to more than three billion.

Anxious Indians raced for supplies after the world's second-biggest population was ordered not to leave their houses for three weeks.

Russia, which announced the death of two patients who tested positive for coronavirus on Wednesday, is expected to follow suit.

President Vladimir Putin declared next week a public holiday and postponed a public vote on controversial constitutional reforms, urging people to follow instructions given by authorities.

In Britain, heir to the throne Prince Charles became the latest high-profile figure to be infected, though he has suffered only mild symptoms.

The G20 major economies will hold an emergency videoconference on Thursday to discuss a global response to the crisis, as will the 27 leaders of the European Union, the outbreak's new epicenter.

China has begun to relax its own draconian restrictions on free movement in the province of Hubei -- where the outbreak began in December -- after the country reported no new cases.

Crowds jammed trains and buses in the province as people took their first opportunity to travel.

But Spain saw the number of deaths surge to more than 3,400 after 738 people died in the past 24 hours and the government announced a 432-million-euro ($467 million) deal to buy medical supplies from Beijing.

The death toll in Italy jumped in 24 hours by 683 to 7,503 -- by far the highest of any country.

The number of French deaths was up by 231 on Wednesday to more than 1,330, and metro and rail services in Paris were cut to a minimum.

Spain and Italy were joined by France and six more EU countries in urging Germany and the Netherlands to allow the issue of joint European bonds to cut borrowing costs and stabilise the eurozone economy.

The call is likely to fall on deaf ears when EU leaders talk on Thursday -- with northern members wary of pooling debt with big spenders -- but they will sign off on an "unprecedented" recovery plan.

At La Paz University Hospital in Madrid, nurse Guillen del Barrio sounded bereft as he related what happened overnight.

"It is really hard, we had feverish people for many hours in the waiting room," the 30-year-old told AFP.

"Many of my colleagues were crying because there were people who are dying alone, without seeing their family for the last time."

Coronavirus cases are also spreading in the Middle East, where Iran's death toll topped 2,000, and in Africa, where Mali declared its first case and several nations announced states of emergency.

In Japan, which has postponed this year's Olympic Games, Tokyo's governor urged residents to stay home this weekend, warning of a possible "explosion" of the coronavirus.

Jerusalem's Church of the Holy Sepulchre, believed by Christians to house Christ's tomb, was shut as Israel tightened movement restrictions.

The impact of the pandemic is also hitting European football, with leagues and tournaments cancelled, while the fate of the Wimbledon tennis tournament could be decided next week.

The economic damage of the virus -- and the lockdowns -- could also be devastating, with fears of a worldwide recession worse than the financial meltdown more than a decade ago.

But financial markets rose after US leaders reached agreement on a stimulus package worth roughly 10 percent of the US economy, an injection Senate Majority Leader Mitch McConnell said represented a "wartime level of investment."

Meanwhile, more than half of all Americans have been told to stay at home, including residents of the largest state, California.

The United States has at least 65,700 cases and 942 people have died.
