Chennai/Bangalore, Dec 1: Crossing a major milestone in the country's space history, ISRO's Mars Orbiter mission today ventured out of Earth's sphere of influence for the first time in an attempt to reach the red planet's orbit.

The critical manoeuvre to place the Mars Orbiter Spacecraft in the Mars Transfer Trajectory was successfully carried out almost an hour past midnight.

During this manoeuvre, which began at 00:49 hours, the spacecraft's 440 Newton liquid engine was fired for about 22 minutes providing a velocity increment of 648 metres/second to the spacecraft.

"Following the completion of this manoeuvre, the Earth orbiting phase of the spacecraft ended. The spacecraft is now on a course to encounter Mars after a journey of about 10 months around the Sun," the Bangalore-headquartered Indian Space Research Organization said in a statement.

ISRO performed the trans-Mars injection, a "crucial event" intended for hurling its Mars Orbiter spacecraft into the planned orbit around the Sun, marking the first step towards the 300 day voyage to reach the orbit of the red planet after crossing roughly 680 million kilometer.

"The Trans Mars Injection (TMI) operations, which began at 00.49 hours (IST) completed," ISRO said.

ISRO has planned four mid-course corrections in case of any deviation along its path to the Martian orbit.

The space agency is scheduled to make four corrections in the course of the spacecraft's voyage to Mars before it is expected to reach the orbit of the red planet in September 2014.

It had performed five orbit-raising manoeuvres on its Mars Orbiter, raising the apogee (farthest point from Earth) of the spacecraft to over 1.92 lakh kilometers, before it performed the "mother of all slingshots."

The spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennae at Byalalu here, the space agency added.

ISRO's PSLV C 25 successfully injected the 1,350-kg 'Mangalyaan' Orbiter (Mars craft) into the orbit around the earth some 44 minutes after a text book launch at 2.38 PM from the Satish Dhawan Space Centre at Sriharikota on November 5, marking the successful completion of the first stage of the Rs 450 crore mission.

New Delhi, Mar 25: The total number of confirmed coronavirus cases in India rose to 562, according to the Ministry of Health and Family Welfare on Wednesday.
This includes 512 active cases, while 40 infected people have already been cured or discharged.
The Union Health Ministry said that total deaths due to the disease now stand at 9, as the second death reported in Delhi is COVID-19 negative. One patient has also migrated due to the infection.
The Central government has taken several steps to contain the rapid spread of the virus including the screening 15,24,266 passengers at the airports.
Prime Minister Narendra Modi had on Tuesday announced a 21-day lockdown in the entire country effective from midnight to deal with the spread of coronavirus, saying that "social distancing" is the only option to deal with the disease, which spreads rapidly.
In a televised address to the nation, Prime Minister Modi said that it is vital to break the chain of the disease and experts have said that at least 21 days are needed for it.
The Prime Minister, who had also addressed the nation last week, said the lockdown has drawn a "Lakshman Rekha" in every home and people should stay indoors for their own protection and for that of their families.

India has jumped past 4.5 lakh coronavirus cases and 14,476 people have succumbed to the viral infection so far. In this backdrop, speaking to IANS in an exclusive interview, AIIMS Director Randeep Guleria said India is also vulnerable to second wave of coronavirus and people should continue to follow social distancing, wearing mask and other precautions, after cases begin to decline.

He added that in order to contain the outbreak of Covid-19, a limited lockdown in hotspots, where volume of cases is very high, may be considered along with a micro-plan to prevent leakage of cases from these areas to other non-containment areas. Excerpts of the interview are below:

Q: Reports say China and South Korea are witnessing a second wave of coronavirus infection, what is this second wave, is India also vulnerable to this?

A: When cases come down significantly, people tend to drop their guard against the viral infection, and this leads to the second wave (which means a sudden increase in the number of cases). After cases begin to decline, people should continue to follow the precautions -- continue to maintain social distancing and wear masks regularly. See what happened in Singapore, it was struck by a second wave of coronavirus. Look, what happened in the 1918 pandemic, people dropped their guard and the second wave of viral infection struck back. If people do not follow social distancing then the spike in cases is apparent. We need to take these precautions at least for one year. India is also vulnerable to this second wave.

Q: If Covid-19 cases continue to rise rapidly, do you think we need another lockdown in areas where volume of cases are very high?

A: A large volume of cases is concentrated in specific areas like hotspots, and in order to maintain things in order, we may need a limited lockdown in these areas. This should be followed by a micro-plan which entails extensive testing of people and also extensive contact tracing of people who have got in touch with positive people. Need to ensure there is no leakage of cases from these areas. People from these areas should not mix with others in non-containment areas. This will aid in containing the outbreak of the virus. People who have developed symptoms should get themselves tested, especially in the containment areas.

Q: With more than 4.5 lakh cases and close to 14,500 deaths, do you think India has reached its peak and a decline in cases is prominent?

A: The cases will continue to increase for some time. The doubling time of cases has also increased. But, the cases will also begin to flatten. Though, it is difficult to give an exact time period in this viral infection, it seems, the growth in cases will flatten in the end of July or beginning of August. A decline will come to this viral infection, but it does not mean that people should drop their guard. As a measure, we need to decrease community participation and citizens should continue to follow social distancing. People should get themselves tested. All these efforts will help in preventing people from contracting this virus. These precautions will also prevent us from the second wave, and we must continue to take precautions. The virus has not gone away, it is still lurking.

Q: India has crossed the 4.5 lakh coronavirus cases so far, although our recovery rate is good, but still 10,000 to 15,000 cases are reported daily. Why do cases continue to spiral, what is the reason?

A: We have to remember a few things -- the bulk of cases are in 10 cities, nearly 70 per cent, and if we take into account cases per million population, the number is not very high, as compared with countries including countries in Europe. Many European countries put together still do not add up to the Indian population. Do not compare India to countries like Italy, Spain etc. We need to focus on hotspots, which contribute to between 70 -80 per cent of cases, and we have to identify cases in these areas at an early stage. The population density is very high in these cities. People in lower socio-economic status are highly vulnerable to the viral infection, as many live together in small spaces and there is a lot of mixing of people happening there. Look at the market places, people are not following social distancing and not wearing masks. In fact, many are in close vicinity of each other.

Jul 1: Gold prices in India hit an all-time high on Wednesday, tracking a global rally, as surging coronavirus cases in many countries raised the metal's safe-haven appeal.

Local gold futures hit an all-time high of Rs 48,871 ($646.66) per 10 grams in early trade, taking their gains to 25% in 2020 so far. The contract had gained nearly 25% in 2019.

However, this dampened the retail demand for gold in India, the world's second-largest consumer of the precious metal.

"Retail demand is negligible. Buyers are postponing purchases anticipating a correction in prices," said a Mumbai-based bank dealer with a bullion importing bank.

In thin trade, dealers were offering a discount of up to $22 an ounce over official domestic prices on Wednesday afternoon, up from the last week's $18. The domestic price includes a 12.5% import tax and 3% sales tax.

The country's gold imports in May plunged 99% from a year earlier as international air travel was banned and jewellery shops were closed amid a nationwide lockdown to curb the spread of coronavirus.

In overseas market, spot gold firmed near an eight-year peak on Wednesday, as a spike in coronavirus cases in the United and States and many other countries has cast a shadow on hopes for a quicker global economic recovery, driving inflows into safe-haven assets.

According to a latest Reuters tally, the coronavirus has infected more than 10.48 million people worldwide so far.
