ISRO- Indian Space Research Organization:

ISRO has launched two foreign satellites of UK which is mainly an earth observational satellite named  NovaSAR and S1-4  from PSLV-C42 . It was launched from Satish Dhawan Centre, Sriharikota (Andhra pradesh) and it is PSLV 44th flight. They both together weighing 889 kg.

The features of the  two satellites of UK are :

  1. NovaSAR - It is an S-band Synthetic Aperature Radar (SAR) satellite which will help in forest mapping ,land use , flood and disaster monitoring and ice cover monitoring.Its lift-off weight is 445 kg.
  2. S1-4 - It is an high resolution optical earth observational satellite which will help in surveying resources , environment monitoring , urban management and for disaster monitoring .Its lift-off weight is 444 kg.

Chandrayaan -2 :

Chandrayaan -2 is ISRO's first inter planetary mission to land rover on any celestial body. Chandrayaan -2 is an advanced  version of Chandrayaan -1 and has been developed by ISRO. It consist of Orbiter ,Lander and Rover configuration.The wheel rover will be move on the lunar surface and will pick up the soil or rock samples for an on-site chemical analysis and the data will be pass on to the earth by chandrayaan-2  orbiter. This mission includes soft landing on moon and moving a rover on its surface. and all the three components will send the data and pictures to the earth.

ISRO  :

ISRO has also inaugurated  S-band polarimetry Doppler Weather Radar (DWR) from  Satish Dhawan Space  Centre ,Sriharikota, Andhra Pradesh . It is developed by BEL (Bharat Electronics Limited ) , Bengaluru under  TOT (Training of Trainers) programme. It covers a ranges of about 500 km and will be used for observation of weather system and events related to this. It is the 7th Radar which is made under "Make In India" programme. It will be generally used to detect the natural disaster associated  with the weather and thus help in saving life and property.

ICESat-2 -satellite mission of NASA:

ICESat -2 
The Antarctica and Greenland loses ice every year because of warm water and hence result in melting of glaciers.IceSAT-2's consist of laser which is designed differently. This new laser system  is the largest earth observation instrument built  by NASA. It will use the technique of Photo Counting.It fires about 10,000 pulses of light every second and then will bounce back and thus help in determining how much ice is densed with proper mapping. It will mainly maps the  sea ice thicknesss in the Antarctica.
Previously ICESat -1 was launched in the year 2003 and this mission was ended in 2009.

Prithvi Defence Vehicle  (PDV) : by DRDO

It was recently launched from  Abdul Kalam Island which is earlier known as wheeler Island. This mission will help India by engaging the targets in the exo-atmosphere region of altitude of above 50 km of the earth's atmosphere.It will able to detect and tracked the enemy's ballistic missile. The new 2 stage solid fueled PDV interceptor fitted with IIR(Imaging Infrared) developed by DRDO. It was first tested in April 2014 but failed to due some problems.
