OceanSat II to aid Sea Fishing

ISRO is planning to launch it’s second in OceanSat series this year. OceanSat  II is more advanced than OceanSat I which was launched into space in 1999. ISRO is also planning to launch a number of satellites to help agriculture also.

The OceanSat-II will have two instruments – ocean colour monitor and scatterometre. The ocean colour monitor would detect the colour of the ocean indicated by phytoplankton (marine organisms including fishes). This information will aid in fishing. The scatterometre will study the interaction between ocean and atmosphere, sea surface temperature, wave height and this information will help the weathermen in forecasting the weather.

The OceanSat-I also has an instrument for monitoring ocean colour and a multi-frequency scanning microwave. The OceanSat-I has been giving information for aiding fishing in the sea fishing zones.

Isro also has plans to launch Insat-3D for monitoring meteorological data, G-SAT-4 for communication facility with experimental navigation payload, Insat-4D with communication facility with transponders and ResourceSat for remote sensing. All these satellites would be launched with the help of indigenous polar satellite launch vehicles (PSLVs).

Satellites for accessing meteorological data and remote sensing will help agriculture as meteorological data are effective tool for weather prediction and crop production and crop production and soil and water conditions can be monitored through remote sensing. ISRO had earlier launched remote sensing satellites and remote sensing operations have been able to estimate crop production particularly that of wheat and rice to near accuracy.

ISRO also has plan to launch AstroSat for gathering astronomical information and MeghaTropics with French collaboration for tropical atmospheric studies within a year.

More detailed information about India’s future Space Missions

Indian’s proud space agency has shown the world what it can do. Chandrayaan 1 is an overwhelming success, not only for ISRO, but for each and every Indians. Many years before, India was denied many advanced technologies by many other countries. Now, we are capable of developing over own technology.

After Chandrayaan 1, ISRO has many innovative plans. Chandrayaan 2 which is an India-Russian joint space mission is all set to kick off on 2012. Mr. Madhavan Nair said that the design for Chandrayaan 2 is ready. Mission is to send a rover to the surface of the moon. The rover will collect the samples from Moon’s surface and analyse it in Moon itself.

In 2013, ISRO is also planning to send spacecraft to Mars. Polar Satellite Launch Vehicle is considered as the work horse of ISRO. But, Geosynchronous Satellite Launch Vehicle will be used to send space craft to Mars. On the same year, an Indian will be sent to space by Russia.Now, Mission to Mars is under planning only.

In 2015, ISRO is planning to develop an own spacecraft to put two Indian Astronauts into space for a seven  day mission.

Two more Chandrayaan instruments to be activated in the middle of December

Two of the 10 remaining scientific instruments onboard India’s first unmanned lunar mission Chandrayaan-1 will be activated in mid-December for conducting experiments.
The sub-kiloelectronvolt (keV) atom reflecting analyser (SARA) and the high-energy x-ray spectrometer (HEX) are scheduled to be activated in mid-December as they need favourable condition from the sun angle. The remaining eight payloads have been energised and are functioning well.
Of the 11 payloads, the moon impact probe (MIP) was successfully lowered onto the lunar surface Nov 14 with excellent results. The other eight instruments are – mini synthetic aperture radar (MiniSAR), moon mineralogy mapper (M3), radiation dose monitor (RADOM), terrain mapping camera (TMC), hyper-spectral imager (HySI), lunar laser ranging instrument (LLRI), imaging x-ray spectrometer (C1XS) and smart near infrared spectrometer (SIR-2).
The MIP camera took about 3,000 images during its 25-minute descent. Some of the images include the ridge of the Shackleton crater and a vivid picture of the field where the probe crash-landed, thus confirming the execution was precise and at the designated place. They are a valuable catch.
The data, received from the mother spacecraft at the deep space network (DSN) at Byalalu, about 40 km from Bangalore, is being caliberated and studied by ISRO scientists.The data is so voluminous that it will take three months to analyse by our experts. The third instrument – the c-band altimeter gave the trajectory of the descent and confirmed whatever we have done was on target. The MIP experiment is unique as the Chinese and Japanese lunar missions did not have such a one.

New pictures from Chandrayaan 1 : Get them now!

The increase in temperature of Chandrayaan 1 Spacecraft is a slight set back for the mission. But, ISRO is hopeful of overcoming it by Mid-January 2009.

I present to you the latest pictures from Chandrayaan 1:(Click for full view)
Moon imagery acquired by HySI Camera and TMC of Chandrayaan-1 on 16 Nov. 2008 (Strip Length - 395 Km.) Lunar craterlet (BARROW H) imaged by Chandrayaan-1 HySI camera (64 Bands) on 16 Nov. 2008 Another HySI image (64 Bands) by Chandrayaan-1 accquired on 16 Nov. 2008
This is the picture of moon's surface taken from lunar orbit by Chandrayaan-1 spacecraft's Terrain Mapping Camera (TMC) on November 15, 2008. Taken over the polar region of the moon, the picture shows many large and numerous small craters. The bright terrain on the lower left is the rim of 117 km wide Moretus crater. This is the picture of moon's surface taken from lunar orbit by Chandrayaan-1 spacecraft's Terrain Mapping Camera (TMC) on November 13, 2008. Taken over the equatorial region of the moon, the picture shows the uneven surface of the moon with numerous craters. On the lower left, part of the Torricelli crater is seen.
