ISRO will follow a gruelling schedule & conduct 5 launches in the next 5 m o n t h s , including the Chandrayaan-2 moon mission.

The missions are: GSLV-FO8 (GSAT-6A satellite), GSLV -MkIII (second development flight), Chandrayaan-2 and PSLV (IRNSS- 1I navigation satellite).

Further, ISRO's GSAT-11 will be launched by Arianespace, by May 2018.

India currently has 45 orbiting satellites & here is a demand for an additional 45 new satellites.


ISRO Chairman Dr K Sivan h a s confirmed that GSAT- 11 will be launched in April or May."

The 5,725- kg satellite, will have 40 Ku & Kaband transponders, providing 14 Gbps broadband speeds.

Since its a large, 5 tonne satellite, it's too heavy for the current GSLV, it will be launched by Ariane.

Last year on June 5, ISRO launched GSAT-19, also a Ka/Kuband broadband satellite, with 16 spot beams capable of delivering 13 Gbps.


In 2019, ISRO will launch GSAT-20, a powerful broadband satellite, with 40 spot beams. Each beam has 2 polarisations, effectively providing 80 beams & a data transfer rate of 60-70 Gbps.

Referring to GSAT-11, GSAT-19 & GSAT-20, ISRO Chairman Dr Sivan said, "Together, all these satellites will provide high bandwidth connectivity of up to 100 gigabit per second, for highspeed internet connectivity in rural areas."


In May, ISRO will launch GSAT-29 using the indigenously developed and manufactured GSLV Mk III rocket from Sriharikota. Next year, GSAT-20 will also be similarly launched.

GSAT-29 is configured around ISRO's Enhanced I-3K Bus and will be the payload for second developmental flight of GSLVMkIII. It carries Ka x Ku multi-beam and optical communication payloads for the first time. The mission targets for Village Resource Centres (VRC) in rural areas.


ISRO's Chandrayan moon & Mars missions have been accomplished on shoe-string budgets.

ISRO's Mars Mission Mangalyaan cost the space agency less money than it took to make the Hollywood space movie "Gravity."

The Chandrayaan-2 moon mission in April, will cost (₹ 800 Crores) less than Hollywood movie 'Interstellar,' (₹ 1,065 Crore or $ 165 million) according to MoS PMO Dr Jitendra Singh.

Chandraayan-2 will carry an orbiter, a lander and a rover to the moon.


On 31 Jan, a SpaceX Falconrocket successfully launched GovSat-1 a communications satellite commissioned by the Government of Luxembourg.

GovSat-1, also known as SES-16, is the first satellite to be launched for LuxGovSat, a partnership between the government of Luxembourg and commercial satellite operator SES. The satellite will provide secure communications for Luxembourg's military and the country's allies, as well as supporting civilian government applications.


NASA has teamed up with the US defence research agency to build robots that can not only refuel and repair satellites, but also sabotage enemy spacecraft in the event of space war. These robotic satellites, known as 'service stations in orbit.'

The service stations will also help clear up space debris. In 2015, there were about 25,000 humanmade objects larger than a human fist and roughly half a million larger than a dime orbiting Earth. These objects travel at high speeds and could pose a serious hazard to new satellites and spacecraft venturing beyond the Earth.


A 2 room, 8,500 Kg Chinese space station Toangyong-1 carrying toxic fuel is falling freely towards Earth. The satellite is expected to fall this March somewhere further north than 43 deg North or further south than 43 deg South. Most of this area is over the ocean.

Toangyong-1 is 60 times smaller than the International Space Station (ISS). Control of the space station was lost in June 2016 making it float arbitrary in Earth's orbit.

Tiangyong-1 carries some amount of rocket fuel hydrazine which is a harmful toxic being able to bring severe damage to human liver and nerves.


On Jan 12, 2018 - India's Polar Satellite Launch Vehicle, in its forty second flight (PSLV-C40), successfully launched the 710 kg Cartosat-2 Series Satellite for earth observation and 30 co-passenger satellites together weighing about 613 kg at lift-off.

The co-passenger satellites comprise one Microsatellite and one Nanosatellite from India as well as 3 Microsatellites and 25 Nanosatellites from six countries, namely, Canada, Finland, France, Republic of Korea, UK and USA.

The total weight of all the 31 satellites carried onboard PSLVC40 is about 1323 kg.


According to K Sivan, Chairman of the Indian Space Research Organisation (ISRO), said "We are working on a dual concept: Increasing the carrying capacity of our heaviest rocket - the 640-tonne Geosynchronous Satellite Launch Vehicle-Mk III (GSLV Mk III) to 6 tonnes. Simultaneously, we are working on lower weight communication satellites."

As a result, India may soon be able to launch even its most powerful home-built satellites.


China has successfully put into service its first high-speed laser communication satellite.

The high-orbit satellite, Shijian-13, has (successfully) completed a two-way high-speed laser communication test between the satellite and the ground, the first of its kind in the world, the China National Space Administration said in a statement.

Shijian-13, launched from Xichang Satellite Launch Centre in southwest China's Sichuan Province in 2017, has a transfer capacity of 20 Gbps and a designed orbital life of 15 years, the state-run Xinhua news agency reported.


Hispasat and Internet provider Eurona will soon launch a package of satellite broadband services in Spain on K-band through satellites Hispasat 36 W-1 and 30 W-6 which cover Europe and the north of Africa.

The services will target isolated areas with no optic fibre coverage and offer speeds of up to 30Mbps with a convergent package priced at Euro 39.90 a month.


The December 2017 launch failure of Russia's Meteor-M 2-1 weather satellite, has been traced to human carelessness. The satellite was launched from Russia's new Vostochny cosmodrome in the country's far east.

Russian deputy prime minister Dmitry Rogozin admitted "The rocket was really programmed as if it was taking off from Baikonur. They didn't get the coordinates right."

Baikonur is the often used cosmodrome which Moscow leases from Kazakhstan.

The rocket also carried 18 smaller satellites belonging to scientific, research and commercial companies from Russia, Norway, Sweden, the US, Japan, Canada and Germany. n
