ISRO released pictures of comet Siding Spring taken by Mars Orbiter Mangalyaan

Dear readers an followers,

While the +European Space Agency, ESA  had placed a robot Philae on Comet 67P/Churyumov-Gerasimenko, the Indian Space Research Organisation (ISRO) released images of Comet Siding Spring, taken by its Mars Orbiter 'Mangalyaan' on October 2014. ISRO's Mars Orbiter had the opportunity to witness the Comet Siding Spring approach Mars on October 19th, for which the spacecraft repositioned itself for its safety.

The Mars Colour Camera on board ISRO's Mars Orbiter has captured the Coma (top bright portion) of the comet partly, as it approached MOM during last 40 minutes of the imaging session before Mars-Comet close encounter, ISRO said in its social networking site along with the pictures.

The India's Mars Orbiter Mission, the Mangalyaan probe is a spacecraft powered by solar arrays and packed with five instruments to study the surface and atmosphere of Mars. The 1350 kg of the spacecraft has been launched with success from a pad at the agency's Satish Dhawan Space Centre in Sriharikota on November 5th 2013. India was particularly proud that MOM was developed with homegrown technology and for a bargain price of about $75 million, a cost that Modi quipped was lower than many Hollywood film budgets. By comparison, NASA's much larger Maven mission cost nearly 10 times as much at $671 million.

It also will search Mars for methane, a key chemical in life processes on Earth that could also come from geological processes. None of the instruments will send back enough data to answer these questions definitively, but experts say the data will help them better understand how planets form, what conditions might make life possible and where else in the universe it might exist India wanted the spacecraft, also called Mangalyaan, meaning "Mars craft" in Hindi, to show the world its ability to design, plan, manage and operate a difficult, deep-space mission. India has already conducted dozens of successful satellite launches, including sending up the Chandrayaan-1 lunar orbiter, which discovered key evidence of water on the Moon in 2008 and validated few month ago.

The country's space scientists are already planning new missions, including putting a rover on the Moon. But space agency chief K. Radhakrishnan said their main focus would be to continue developing technologies for commercial and navigational satellite applications.

Amazing picture of the comet Siding Spring taken from NASA'rover Opportunity from martian surface

Dear readers, and followers,

as you know, All mars orbiter, as the Indian spacecraft, has been repositioned in order to reduce the effect of and not be disturbed by the flyby of the comet Siding Spring. The other orbiters from NASA orbiters around Mars confirmed their healthy status Sunday after each took shelter behind Mars during a period of risk from dust released by a passing comet. The rover opportunity which is on Mar's land took an amazing picture of the comet Siding Spring.

This incredible image showing the comet Siding Spring in the Martian sky was taken by Nasa's opportunity rover on the surface of Mars - the first ever image of a comet from another planet. It is hoped the event will provide researchers with an unprecedented opportunity to gather data on comets.

Mars orbiters healthy after Siding Spring comet flyby

Dear readers and followers,

Last week, we informed you that a huge ice comet, called C/2013 A1, will be so close to Mars on Sunday October 19th. All mars orbiter, as the Indian spacecraft, has been repositioned in order to reduce the effect of and not be disturbed by the flyby of the comet Siding Srping. The other orbiters from NASA orbiters around Mars confirmed their healthy status Sunday after each took shelter behind Mars during a period of risk from dust released by a passing comet.

Mars Odyssey, Mars Reconnaissance Orbiter and the Mars Atmosphere and Volatile Evolution (MAVEN) orbiter all are part of a campaign to study comet C/2013 A1 Siding Spring and possible effects on the Martian atmosphere from gases and dust released by the comet.

The comet sped past Mars today much closer than any other know comet flyby of a planet. Actually, the comet missed the red planet by just 140,000 kilometers.

As we said in Friday October 17th, the comet could be observed from Earth, here, an image of the comet C/2013 A1 taken from the ESA's Optical Ground Station, equipped with a 1-meter telescope, on Tenerife, Canary Islands.

ISRO repositioned Mars Orbiter to be not affected by the comet Siding Spring

Dear readers and followers,

Indian Space Research Organisation (ISRO) has repositioned its Mars Orbiter, as the national space agency along with its counterparts around the world are expecting Comet Siding Spring to fly by the Red Planet on October 19. ISRO, but also the US space agency NASA and other space agencies in the world, which have sent their missions to the Red Planet have taken precautionary measures to save their satellites from any possible collision with the space debris, which might be facilitated by the movement of the Comet near Mars. 

Kiran Kumar, Director of Space Application Centre from ISRO aannouncedthat they have repositioned the Mars Orbiter, as the Comet Siding Spring is expected to be close to the Mars on October 19. They have taken the Orbiter to a position farthest from the tail of the Comet so that it doesn't affect the satellite,".

According to NASA, Comet Siding Spring has traveled many billions of km and would come within about 140,000 km of Mars on October 19. The comet comes from the Oort Cloud, material left over from the formation of the solar system. India is the fourth country to send a mission to the red planet. This was in November 2013 !

All five operational spacecraft orbiting the Red Planet — NASA's Mars Odyssey, Mars Reconnaissance Orbiter and MAVEN probes, India's Mangalyaan spacecraft and Europe's Mars Express, will observe the flyby. And NASA's Opportunity and Curiosity rovers will crane their necks up to watch from the Martian surface as well.

The trajectory of the comet Siding Spring so close to Mars

Dear readers and followers,

a comet will buzz Mars this Sunday, October 19th in an epic encounter that has astronomers around the world tingling with excitement. The comet is know by the name Siding Spring, also called as C/2013 A1. The comet will miss the Red Planet by just 140,000 kilometers at 2:27 p.m. EDT (1827 GMT) on Sunday. For comparison, the moon orbits Earth at an average distance of 384,600 km.

While the comet won't put on a show for skywatchers on Earth, the fleet of robotic explorers at Mars will get an eyeful. They will study the comet, as well as any observable interactions between its shed particles and the thin Martian atmosphere.

Comets are icy leftovers from the solar system's birth, and Siding Spring is a pristine object that has never been "heat-treated" by the sun before. So any insights about the comet's composition and behavior could help researchers better understand how our cosmic neighborhood began taking shape 4.6 billion years ago.

"This is a cosmic science gift that could potentially keep on giving, and the agency's diverse science missions will be in full receive mode," former astronaut John Grunsfeld, associate administrator for NASA's Science Mission Directorate, said in a statement. "This particular comet has never before entered the inner solar system, so it will provide a fresh source of clues to our solar system's earliest days."

All five operational spacecraft orbiting the Red Planet — NASA's Mars Odyssey, Mars Reconnaissance Orbiter and MAVEN probes, India's Mangalyaan spacecraft and Europe's Mars Express, will observe the flyby. And NASA's Opportunity and Curiosity rovers will crane their necks up to watch from the Martian surface as well.
