PSLV-C16 rocket carrying 3 spacecrafts which include India's latest remote sensing spacecraft "ResourceSat-2" was succesfully launched on 20th April,2011 from Satish Dhawan Space Center, SHAR, Sriharikota at 10:12 hrs. This is the 18th launch of PSLV and 17th succesful launch of PSLV.
PSLV-C16 has placed the three spacecrafts into an orbit of 822 Kms. above the surface of earth. Two are Indian spacecrafts and the third one is a Singapore spacecraft. The Indian spacecrafts are RESOURCESAT-2 (1206 Kg) and YOUTHSAT (92 kg) and the Singapore Spacecraft is X-SAT (106 Kg).
The Resourcesat-2 is indian remote sensing spacecraft which will help in applications which include natural resource monitoring, environmental assessment and also disaster management related activities. Resourcesat-2 would provide a three-tier imaging through AwiFS LISS-3 and LISS-4 cameras.
The Youthsat spacecraft contains three payloads, of which two payloads are Indian and the third one is Russian. Together these three payloads are useful to study and investigate the composition, energetics and dynamics of the Earth's upper atmosphere.
The X-SAT is mainly intended to demonstrate technologies related to satellite based remote sensing and onboard image processing.
You can see a video of the launch.

Biggest moon in 20 years - Super Moon 19th March,2011
The moon is going to come very closer to earth on 19th March,2011 which is the closest distance in the last 20 years. There are people who believe that when the moon passes near to us, the earth jumps up to greet moon and thus we see all kinds of volcanoes, earth quakes, floods, tidal waves, tsunamis etc.
Similar big moon happened in the year 2005 and we have seen a natural disaster in the year 2005. There was Tsunami in Indonesia which triggered by earth quake 9.2 in Ritcher scale in 2005. 2,00,000 people lost their lives in that earth quake in Indonesia.
The people of Japan observed many UFOs shortly before being hit by earth quake and tsunami. There is a belief that UFOs appear at places where there would be some natural disaster going to happen.
The big moon of 19th March,2011 was 221,565 miles ( 3,56,575 kilometers) away from earth. This is the biggest and brightest moon in the past 20 years. many people believe that this would trigger natural disasters like earth quake and tsunami on earth. But NASA scientists say that this kind of claims are non sense. The full moon of 19th March,2011 appeared 14% bigger and 30% brighter than other days.
This is the photograph of the big moon taken by a person in Washington. This is an amazing view of moon of 19th March,2011 when the moon was at perigee, the closest point to earth in its orbit - using a camera-equipped telescope.
This is another big moon photo taken by a sky watcher in Manipal in India on 19th March,2011.

Japan's Earth quake on 11th March,2011 gives rise to doubts on Nuclear power
There was an earth quake and Tsunami in Japan on 11th March,2011. Due to this earth quake and Tsunami there was a great loss to the properties and lives of people of Japan.
There were explosions at the three nuclear reactors in Fukushima Daiichi nuclear complex after the quake. This has put a question mark on the future of the nuclear power and the nuclear industry. People are fearing about what would happen if the radiation was leaked. It is not known what would be the impact of the explosions on the health, and environment. This explosion has created lot of fears among the people there. The nuclear plant showed dangerously low water levels, which exposed the nuclear fuel rods which may increase the threat of radiation to reach nearby public. It is known that at least 190 people were exposed to the radiation. Nearly 1,85,000 people were vacated from the place near the nuclear power plant.
But according to Mr. Ravi Krishnaswamy, Frost & Sullivan's Asia-Pacific Vice President of Energy and Power systems practice, Japan's nuclear power sector has a safety record for several decades.
The Japanese government also assures the public and international community that the health danger from release of radio active steam from the explosions is very very low and it seems the containment wall for the nuclear plant seems to be intact.
There is an increasing list of plans for nuclear power plants. As of 2010, we can see almost 56 nuclear reactors constructed worldwide and Asia-Pacific region accounts for more than half of these nuclear reactors.
Now there is a requirement for all the nuclear power plants which are currently in operation to undergo a review of safety processes whether they are located in earthquake-prone zone or not.
