TripleSat Satellite Sensor (0.8m)
The TripleSat/DMC3 Constellation was successfully launch on July 10, 2015 from Dhawan Space Centre, Sriharikota, India and delivers 0.8m panchromatic and 3.2m multispectral high resolution satellite imagery.
The TripleSat satellite constellation consist of three (3) identical optical earth observation satellites, which makes it possible to target anywhere on earth once per day. Satellite imagery is available at 0.8m high-resolution imagery products with a 23.4km swath. Both space and ground segments have been designed to efficiently deliver guaranteed timely information.

The 2020 Giro Italia was to have taken place from 9 to 31 May 2020, as the 103rd edition of the Giro d'Italia, a three-week Grand Tour cycling stage race. The start of the 2020 Giro (known as the Grande Partenza) had been planned to take place in Budapest, Hungary, which would have been the 14th time the Giro has started outside Italy, and the first time a Grand Tour has visited Hungary. The event was jeopardised by the COVID-19 pandemic in Italy, and in March 2020 it was postponed. UCI announced that both Giro and Vuelta will take place in autumn after the 2020 UCI Road World Championships.&n..
The 2020 Dakar Rally was the 42nd edition of the event and the first edition held in Saudi Arabia. The event started in Jeddah on 5 January and finished in Al-Qiddiya 17 January after 12 stages of competition. The rally was marred by the fatal accidents of Portuguese motorcyclist Paulo Gonçalves on stage 7 and Dutch motorcyclist Edwin Straver on stage 11. After 11 years in South America, the event was held in the Asian continent for the first time ever. Organisers admitted that there was "hesitation" before the decision to hold the event in a country which has been under fire over human rights..
