Remote sensing(spy) Radar Imaging Satellite(RISAT 1) launched successfully

[Nothing]

just got news it is successful ...

Congrats to ISRO and all people who worked day and night for such a gr8 successful..
You made India proud once again ..

RISAT-1 (short for Radar Imaging Satellite - 1) is the first of the RISAT series of Indian remote sensing satellites built by the Indian Space Research Organisation (ISRO). It uses a C-band Synthetic Aperture Radar (SAR) for all-weather earth observation.
According to ISRO officials, RISAT-1 at 1,850 kilograms (4,100 lb) is the heaviest microwave satellite to be built by India. While the RISAT-1 was the first satellite of the RISAT series to be built, it will be the second to be launched.[2] RISAT-1 is in queue for launch by ISRO's PSLV-XL rocket in April 2012.
Previous Indian remote sensing satellites relied mainly on optical and infrared sensors. RISAT-1 uses an indigenously developed C-band SAR, operating in multi-polarisation, multi-resolution modes.[2]
The fabrication and launch of RISAT-1 was postponed in the aftermath of the 2008 Mumbai attacks in order to prioritize the launch of RISAT-2 with its X-band SAR of Israeli origin.[3][4][5]
The features of RISAT include:
160 x 4 Mbps data handling system
50 Newton-meter-second reaction wheels
SAR antenna deployment mechanism
Phased array antenna with dual polarisation
RISAT-1 has a resolution of 3m-50m. It also supports a spotlight mode for prolonged focus on a given geographical area at a resolution of 1m.[1] Most of the design and the installation of basic instrument subsystems for the satellite was done in 2010.

20th consecutive successful flight of PSLV..

It was gr8 to see it live..

ISRO PSLV launches with RISAT-1 satellite | NASASpaceFlight.com

The Indian Science Research Organisation launched the twenty first PSLV Thursday morning, carrying the RISAT-1 radar imaging satellite into low Earth orbit. Liftoff from the First Launch Pad at the Satish Dhawan Space Centre occurred on time at 00:17 UTC (05:47 local time).

Radar Imaging Satellite 1, or RISAT-1, is the second satellite of India’s RISAT series. The smaller RISAT-2 satellite was launched in 2009, and is believed to incorporate Israeli technology. RISAT-1 is expected to carry an all-Indian radar imaging payload. The satellite has a mass at liftoff of 1,858 kilograms, making it the most massive spacecraft launched by a PSLV to date, and carries a c-band microwave synthetic aperture radar, operating on a frequency of 5.35 gigahertz.

After a highly successful launch of the Agni V, India today launched its own 'spy satellite' RISAT-1. It was powered by the Polar Satellite Launch Vehicle (PSLV) from Sriharikota at 5.47 am this morning. The indigenously made satellite will have day and night viewing capability and will be able to see through cloud cover.

Isro seeks Balaji's blessing for launch

Ahead of the blast-off of the PSLV-C19 satellite launcher, scheduled for Thursday, Indian Space Research Organisation (Isro) scientists visited the Lord Venkateswara temple at Tirumala on Wednesday and sought the benediction of deity Balaji for the satellite’s flight into the outer space.

Isro Chairman K Radhakrishnan, who led the team to Tirumala, carried a model of the PSLV-C19 and placed it at the feet of the deity in the sanctum sanctorum. “I came to pray for its successful flight,” Radhakrishnan told reporters later. Special rituals were performed by a team of temple priests led by chief priest Ramana Dikshitulu.

Temple authorities said the ritual by Isro officials was not unusual as it had become a practice for public and private R&D institutions to seek the blessings on the eve of any test launch.

Thanks to Balaji too

greattt job isro.

 

[kriish]

congratz ISRO for the success

 

[shuntmaster]

WOW.. That was a really surprising breaking news.. could not believe my eyes when I first saw it on the front page.. wonderful news.. One more feather is ISRO's cap and one more layer of shield in the country'd defence.
After Agni-V and textbook 20th consecutive successful launch of PSLV, Indian rocket scientists are on a roll...

 

[Speaker]

- 20th successive successful launch of PSLV by ISRO.
- Indigenous design and execution
- Project director - Ms. N. Valarmathi - another one to make women proud after Ms. Tessy Thomas!

Top 10 facts about RISAT-1, India's own 'spy satellite'

New Delhi: After a highly successful launch of the Agni V, India today successfully launched its own 'spy satellite' RISAT-1. It was powered by the Polar Satellite Launch Vehicle (PSLV) from Sriharikota at 5.47 am this morning. Here are the top 10 facts on RISAT-1:

1. Weighing at 1528 Kg, RISAT-1 is the heaviest satellite ever launched by India.

2. It will be powered by a 321 tonnes rocket, the most powerful Polar Satellite Launch Vehicle (PSLV).

3. This is the third time that ISRO is using a PSLV-XL (Extra Large) rocket. It was first used in October 2008 to put Chandrayaan-1 in orbit and again in July 2011 during the communication satellite GSAT-12 launch.

4. The indigenously made satellite has day and night viewing capacity and will not be blinded by cloud cover.

5. RISAT-1 will help in crop monitoring and flood forecasting. It will give India the ability for continuous surveillance.

6. The satellite carries a C-band Synthetic Aperture Radar (SAR) payload, operating in a multi-polarisation and multi-resolution mode to provide images with coarse, fine and high spatial resolutions. It has a best resolution of up to 1 m

7. It has taken ISRO 10 years to make this sophisticated satellite. So far PSLV has consecutive 19 successful launches.

8. The total cost of mission is about 500 crores. While the cost of the rocket is about 120 crores, the satellite costs around 380 crores. However, none of them are insured.

9. The project Director N Valarmathi, is the first woman to head a remote sensing satellite project, and the second to be the satellite project director at ISRO.

10. Apart from RISAT-1, India already has another spy satellite RISAT-2 acquired from Israel which was launched in 2009.

Jai Bharat!
