PSLV-C16 Resourcesat-2 mission Successful 18th launch Successful by ISRO

PSLV-C16 Resourcesat-2 mission Successful 18th launch
Successful by ISRO
On Wednesday ISRO got success

Today's PSLV flight was its 17th successive mission after the failure of its maiden voyage in September 1993.
The PSLV has an impressive track record of 16 uninterrupted launches. This is the 18th launch and 17th successive flight of PSLV by ISRO.

India's PSLV-C16 rocket successfully launched into orbit the latest remote sensing satellite Resourcesat-2 that would study and help manage natural resources along with two nano satellites.

Polar Satellite Launch Vehicle placed in a 'Polar Sun Synchronous Orbit' Resourcesat-2, Youthsat and X-Sat about 18 minutes after it blasted off from the Satish Dhawan Space Centre launch pad here, 90 km from Chennai, at 10.12 am.

The 1,206 kg Resourcesat-2 with a space life of five years replaces Resourcesat-1 launched in 2003 and would provide data with enhanced multi-spectral and spatial coverage on natural resources.

Besides Resourscesat-2, the PSLV rocket also launched Youthsat, weighing 92 kg, a joint Indo-Russian nano satellite for stellar and atmospheric studies.

The Resourscesat-2 with three high resolution cameras on a single platform would capture images that will be useful in assessing the health of crops, monitoring deforestation and water levels in reservoirs and lakes besides the snow-melt in the Himalayas.

Apart from the three cameras with high, medium and coarse resolutions, Resourcesat-2 also has two solid state recorders with a capacity of 200 GB each to store images which can be accessed by the ground stations
3 Cameras they are
High resolution linear imaging self scanner LISS 4 operating in three spectral bands in the visible and near infrared region VNIR with 5.8 m spatial resolution and steerable up to +- deg across track to achieve a five day revisit capability.

A medium resolution LISS3 operating in three spectral bands in VNIR and one in short wave infrared SWIR band with 23.5 metre spatial resolution

A coarse resolution advance wide field sensor AWIFS operation in three spectral bands in VNIR and one band in SWIR with 56 metre spatial resolution.

The third satellite was 106-kg X-sat, an image applications spacecraft built by Nanyang Technological University, Singapore.
This is the first time; ISRO is launching a Singapore-built satellite.

It also carries Automatic Identification System (AIS) from COMDEV, Canada, as an experimental payload for ship surveillance in VHF band to derive position, speed and other information about ships.

Youthsat is a join Indo Russian satellite for stellar and atmospheric studies with the participation of students from universities at graduate and post graduate level.
With a mass of 92 Kg Youthsat intends to investigate the relationship between solar variability and thermosphere ionosphere changes.
The satellites carry three payloads of which two are Indian and one Russian. Together they form a unique and comprehensive package of experiments for the investigation of the composition, energetics and dynamics of earth’s upper atmosphere.

The Indian Payloads are –
Rabit – Radio beacon for lonosperic Tomography which is a dual frequency beacon payload for mapping the total electron content Tec of the ionosphere.
Limb viewing hyper spectral imager – is designed to perform airglow measurement of the Earths upper atmosphere 100 to 1100 KM.

XSAT – is the third payload of PSLV 16, is a Singapore first satellite weighing 106 kg at lift off, XSAT is a mini satellite with a multispectral camera IRIS as its primary payload.
XSAT mission mainly intends to demonstrate technologies related to satellite remote sensing and onboard image processing.

The Russian payload SOLRAD monitors the solar X AND ray flexes and helps to study solar cosmic ray flux parameters and conditions of their penetration in the earth’s magnetosphere.

So far during 1994-2010 period, a total of 44 satellites, of which 25 satellites are from abroad and 19 are Indian satellites, were launched by PSLV.
