Morocco successfully launched its second earth observation satellite named Mohammed VI-B on board of Arianespace Vega rocket from launch pad at Guiana Space Center in Kourou, French Guiana in South America. It will be placed at same orbit as its twin satellite Mohammed 6-A, the first Moroccan satellite launched in November 2017 also on Vega rocket. The launch completes Morocco’s two-satellite constellation for Earth observation.
The 1,100-kilogram satellite was developed by Thales Alenia Space and Airbus Airbus Defence and Space. Airbus had built platform of satellite while Thales Alenia Space supplied payload and ground segment for image processing. It will be mainly used for mapping, land surveying, agricultural monitoring, prevention and management of natural disasters, monitoring changes in the environment and desertification as well as border and coastal surveillance.
It is multinational company founded in 1980. It is world’s first commercial launch service provider. It has its headquarters in Courcouronnes, Essonne, France. It offers a number of different launch vehicles: heavy-lift Ariane 5 for dual launches to geostationary transfer orbit (GTO), Soyuz-2 as medium-lift alternative, and solid-fueled Vega for lighter payloads. As of May 2017, Arianespace has launched more than 550 satellites in 254 launches over 34 years. It uses Guiana Space Center in French Guiana as its main launch site. ISRO uses Arianespace’s services for launching its heavy satellites. Arianespace’s Vega is a four-stage rocket designed by Arianespace launch small commercial and science satellites into orbit. The rocket is 98 feet (30 meters) tall and can launch payloads of up to 2,500 kilograms (5,511 pounds) into orbit.
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.
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.
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.
