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 5: The primary classes of all schools in the national capital will remain closed till March 31 to prevent a possibility of spread of coronavirus, Deputy Chief Minister Manish Sisodia announced on Thursday.

According to Directorate of Education (DoE) officials, while elaborate guidelines have been issued about preventive measures for coronavirus, students of nursery and primary classes are too young to understand the risk, making them more prone to infectious diseases.

Sisodia, who also holds the education portfolio, tweeted, "As a precautionary measure to prevent the possibility of spread of COVID-19 amongst our children, Delhi Government has directed the immediate closure of all primary schools (Govt/ aided/ private/MCD/NDMC) till 31/3/20(sic)."

A senior DoE official said, "Elaborate guidelines have already been issued. However, students of nursery and primary classes are too young to understand the risks associated with COVID-19. Thus they are more prone to infectious diseases and mingle around with classmates more often."

"It will be good if they are trained in the do's and dont's under the care and supervision of their parents at home. However, students of classes other than primary will continue to come to schools or examination centres for writing their examination as per schedule. The teaching, as well as non-teaching staff, will also attend regular school," the official said.

As of now, the number of confirmed COVID-19 cases in the country stands at 30, including 16 Italian tourists. The figure includes the first three cases reported from Kerala last month who have already been discharged following recovery.

Alerted by the coronavirus case reported in Delhi-NCR, schools in the region have sent out advisories to parents suggesting that they do not send their wards to attend classes even in case of mild cough or cold, and saying that they may declare holidays if the need arises. A few schools have announced already holidays and others have advanced their spring break.

New Delhi, Mar 9: The Delhi Police Special Cell on Monday arrested a PFI member Danish from UP''s Moradabad for allegedly spreading fake propaganda during anti- CAA protests.

"Danish was the head of the Counter Intelligence Wing of PFI and has been actively participating in the anti-CAA protest across the city," sources in the Delhi Police Special Cell said.

Sources further claimed that his arrest has given clues regarding the Information war by the Popular Front of India (PFI).

The FIR related to the protest was filed by the Crime Branch but since the larger conspiracy regarding the Delhi riots is being probed by the Cell, the matter has been transferred to them.

Delhi Police Special Cell had on Sunday arrested a Kashmiri couple from Okhla for alleged links with Islamic State (IS) Khorasan module.

The couple have been identified as Jahanjeb Sami (husband) and Hinda Bashir Beg (wife). The police have seized some objectionable material from them and were interrogating them.

When asked about the couple, the sources said, "Officers of CERT-In are analysing the Eight Mobile phones and Laptop of the couple to question them further."

The couple being an active member of ISJ&K was operating from the Valley but later shifted their base to Delhi post internet clampdown.
