What made Prime Minister Narendra Modi happy?

A picture is worth a thousand words and this is exactly what made Prime Minister Narendra Modi happy.

After seeing the success of ISRO launching 20 satellites in a go, Modi expressed his happiness on Instagram and Twitter.

In a precision launch, PSLV-C34 took off from the second launch pad of Satish Dhawan Space Centre, about 110 km from Chennai at 9.26 AM and placed the Cartosat-2 Series and 19 others in the designated polar Sun Synchronous Orbit (SSO) about 30 minutes later in clear skies.

The 727.5 kg Cartosat-2 series satellite will provide regular remote sensing services with its panchromatic and multispectral cameras and its imagery will be of multiple use. Of the 19-satellites, 12 are earth imaging "Dove satellites" of USA and another American satellite. The rest are from Canada (two) and one each from Germany and Indonesia. Two academic satellites are from Sathyabama University (Sathyabamasat) in Chennai and from College of Engineering (Swayam) at Pune.

Use of Cartosat 2 includes cartographic, urban and rural applications, coastal land use and regulation, utility management like road network monitoring and water distribution.

Also, creation of land use maps, precision study,change detection to bring out geographical and man-made features and various other Land Information System and Geographical Information System applications can be done. It is similar to the earlier Cartosat-2, 2A and 2B.

With Wednesday's launch of 20 satellites, PSLV beat its 2008 record when it placed in orbit 10 satellites in a single launch into various Low Earth Orbits. This is the 14th flight of PSLV in "XL" configuration known for its capacity to carry more load which uses 'solid strap-on motors'. The total weight of all the 20 satellites carried onboard PSLV-C34 is about 1288 kg.

India has 11 operational earth observation satellites, including RESOURCESAT-1 and 2, CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2 are in orbit.

Beginning in 1988, ISRO had launched many remote sensing satellites (for earth observation) and the data are for varied use including agriculture, water and ocean resources besides disaster management.
