Indian Space Research Organization (ISRO) has given us many reasons to celebrate in the past, and it is back once again with good news. The space agency is going to help the US, which is self-sufficient in space technology , launch its satellite from India's launch pad at Sriharikota . The US is the 20th country seeking India's help for launching its satellite; ISRO scientists have earlier launched 45 satellites for 19 countries. 

However, what really makes this news special is that India's Polar Satellite Launch Vehicle will push the US satellite into the orbit. Besides this, other three major ISRO accomplishments this year had been: 

1) 100 days of Mangalyaan: RememberMangalyaan ? It entered the Red Planet's orbit on September 24, 2014 after a 666-million-km journey from Earth in over 10 months, and made India the first country to taste success in its maiden Mars mission . The satellite sent to Mars was none other than Mangalyaan, which successfully completed 100 days on January 1, 2015. It is still in the pink of its health and is busy collecting scientific data. 

2) Launch of India's 4th navigational satellite: ISRO successfully launched anavigation satellite using the Polar Satellite Launch Vehicle (PSLV) from Sriharikota on March 28, 2015. It will help the country to have its own version of the Global Positioning System (GPS), useful in everyday life for navigation. Having an accuracy of less than 20 meters, this system is comparable to the best in the world. 

3) ISRO launches five British satellites: On July 11, 2015, Indian scientists successfully launched five British satellites into the orbit from Sriharikota. Britain not only rented premium space from ISRO but also hired a rocket for the first time. The total weight of the British satellites is 1,440 kg, making this the heaviest commercial launch ever to be undertaken by India. 

4) Chandrayaan, 2008: India’s first unmanned lunar probe was launched almost a decade ago and was a landmark in India’s space mission. Isro joined an elite list of just six space organisations to send an orbiter to the moon. A Tricolor was hoisted on the moon but Isro lost contact with Chandrayaan soon after.

The Indian space agency is now busy preparing for the launch of GSLV-Mark-II, probably around August 27. According to an official, the 2.1-tonne capacity GSLV-Mark-II would carry acommunication satellite. It would also launch seven other satellites by March 2016. And if all goes well, the Indian space agency might start its mission to Venus by end of this year.
