ISRO has successfully launched GSAT-17 communication Satellite onboard the Ariane-5 launch vehicle from the Guiana Space Center at French Guiana on June 28. GSAT-17 will be the ISRO’s third satellite that is launched within a span of three months.

Salient Highlights

The 3,477-kg GSAT 17 communication satellite will be placed in the geostationary orbit and will have a mission life of 15 years.

The satellite will be an addition to the current fleet of 17 Indian communication satellites that are already providing services from space.

Apart from providing communication services, the satellite will provide meteorological and satellite-based data to help rescue services which were earlier provided by geostationary satellites called Indian National Satellite System (INSAT).

GSAT-17 will provide continuity of services of operational satellites in C, extended C and S bands

Once launched, ISRO’s Master Control Facility at Hassan in Karnataka and Bhopal in Madhya Pradesh will take over and place the satellite in geostationary orbit. GSAT-17 was designed and assembled at the ISRO Satellite Centre in Bengaluru.

In addition, GSAT-17 will also launch communication satellite Hellas Sat 3-Inmarsat S EAN. Hellas Sat 3 will provide directly to home television and telecom services across Europe, West Asia and South Africa. Inmarsat is set to provide in-flight Internet facilities for European airlines.

Launch Vehicle

As ISRO is yet to have a launcher that is capable of lifting payloads above 2,000 kg. ISRO has just started testing the GSLV-Mark III for this purpose.

GSAT-17 will be the 21st Indian launch for the Arianespace. ISRO’s upcoming GSAT- 11 which will weigh more than 5,000 kg will also be launched by Arianespace.

Explained: Petya Ransomware Cyberattack

Petya Ransomware is part of a new wave of cyber-attacks and has infected computer servers across the world.

Extent of Attack

India 

In India, the ransomware has crippled the operations at one of the terminals of the Jawaharlal Nehru Port Trust. The affected terminal was being operated by AP Moller-Maersk. The company operates the Gateway Terminals India (GTI) which has a capacity to handle 1.8 million standard container units. The attack has impacted the external trade by affecting the systems dealing with the cargo and ships at the country’s largest port.

World 

The Petya ransomware has hit computer servers all across Europe. Ukraine and Russia are the worst affected countries. The ransomware has also impacted some companies in the US and other Western European countries.

In the severely affected Ukraine, government offices, energy companies, banks, cash machines, gas stations, and supermarkets, Ukrainian Railways, Ukrtelecom, and the Chernobyl power plant has been worst affected.

Petya ransomware

Petya is a ransomware, similar to the Wannacry ransomware. However, it is a variation of the WannaCry cyber-attack. It follows the WannaCry’s pattern and locks up the computer data and cripples the Enterprise services in the corporate sector. Researchers are yet to find who is responsible for this attack. The ransomware demands $300 Bitcoins as ransom to unlock computer’s files. The attack is believed to have originated against an update used on a third-party Ukrainian software called MeDoc. This explains why Ukraine is the worst affected.
