NASA Instruments Reveal Water Molecules on Lunar Surface and on 24th September 2009, NASA declared this fact officially.
NASA scientists have discovered water molecules in the polar regions of the moon. Instruments aboard three separate spacecraft revealed water molecules in amounts that are greater than predicted, but still relatively small. Hydroxyl, a molecule consisting of one oxygen atom and one hydrogen atom, also was found in the lunar soil. The findings were published in Thursday's edition of the journal Science
NASA's Moon Mineralogy Mapper, or M3, instrument reported the observations. M3 was carried into space on Oct. 22, 2008, aboard the Indian Space Research Organization's Chandrayaan-1 spacecraft.
Jai Ho India...

Oceansat-2 is an Indian satellite envisaged to provide service continuity for the operational users of OCM (Ocean Color Monitor) data as well as to enhance the application potential in other areas. The main objectives of OceanSat-2 are to study surface winds and ocean surface strata, observation of chlorophyll concentrations, monitoring of phytoplankton blooms, study of atmospheric aerosols and suspended sediments in the water.
Oceansat-2 is ISRO’s second in the series of IRS satellites dedicated to ocean research, and will provide continuity to the applications of Oceansat-1 (launched in 1999). Oceansat-2 will carry three payloads including an Ocean Colour Monitor (OCM-2), similar to the device carried on Oceansat-1. Data from all instruments will be made available to the global scientific community after the post-launch sensor characterization, which is expected to be completed within 6 months from the launch. Oceansat-2 is launched from SDSC (SHAR) on September, 2009 using PSLV- C14.
The mission objectives of Oceansat-2 are to gather systematic data for oceanographic, coastal and atmospheric applications. The main objectives of OceanSat-2 are to study surface winds and ocean surface strata, observation of chlorophyll concentrations, monitoring of phytoplankton blooms, study of atmospheric aerosols and suspended sediments in the water.
Oceansat-2 will carry two payloads for ocean related studies, namely, Ocean Colour Monitor (OCM) and Ku-band Pencil Beam Scatterometer. An additional piggy-back payload called ROSA (Radio Occultation Sounder for Atmospheric studies) developed by the Italian Space Agency (ASI) is also proposed to be included. The major applications of data from Oceansat-2 are identification of potential fishing zones, sea state forecasting, coastal zone studies and inputs for weather forecasting and climatic studies.
The scientific payload contains three instruments. Two are Indian and one is from the Italian Space Agency.
* Ocean Colour Monitor (OCM) - OCM is a 8-band multi-spectral camera operating in the Visible – Near IR spectral range. This camera provides an instantaneous geometric field of view of 360 meter and a swath of 1420 km. OCM can be tilted up to + 20 degree along track. The Ku-band pencil beam scatterometer is an active microwave radar operating at 13.515 GHz providing a ground resolution cell of size 50 x 50 km. It consists of a parabolic dish antenna of 1 meter diameter which is offset mounted with a cant angle of about 46 degree with respect to earth viewing axis. This antenna is continuously rotated at 20.5 rpm using a scan mechanism with the scan axis along the +ve Yaw axis. By using two offset feeds at the focal plane of the antenna, two beams are generated which will conically scan the ground surface. The back scattered power in each beam from the ocean surface is measured to derive wind vector. It is a improved version of the one on Oceansat-1.
* Scanning Scatterometer (SCAT) - SCAT is an active microwave device designed and developed at ISRO/SAC, Ahmedabad. It will be used to determine ocean surface level wind vectors through estimation of radar backscatter. The scatterometer system has a 1-m parabolic dish antenna and a dual feed assembly to generate two pencil beams and is scanned at a rate of 20.5 rpm to cover the entire swath. The inner beam makes an incidence angle of 48.90° and the outer beam makes an incidence angle of 57.60° on the ground. It covers a continuous swath of 1400 km for inner beam and 1840 km for outer beam respectively. The inner and outer beams are configured in horizontal and vertical polarization respectively for both transmit and receive modes. The aim is to provide global ocean coverage and wind vector retrieval with a revisit time of 2 days.
* Radio Occultation Sounder for Atmospheric Studies (ROSA) - ROSA is a new GPS occultation receiver provided by ASI (Italian Space Agency). The objective is to characterize the lower atmosphere and the ionosphere, opening the possibilities for the development of several scientific activities exploiting these new radio occultation data sets.
India successfully launched its 16th remote-sensing satellite Oceansat-2 and six nano European satellites in 1,200 seconds with the help The Ocean Monitoring Satellite Oceansat-2 is seen 18 minutes after blast off in Chennai. of Polar Satellite Launch Vehicle (PSLV- C-14) from Sriharikota on Wednesday. The launch was carried out as per schedule at 11.51 am and ended at 12.06 pm. The 44.4-metre tall, 230-tonne Indian rocket Polar Satellite Launch Vehicle (PSLV) freed itself from the launch pad at the spaceport and lifted itself up, lugging the 960-kg Oceansat-2 and the six nano satellites all together weighing 20 kg.
In copybook style, the rocket first flung out Oceansat-2 at an altitude of 720 km above the earth in a sun-synchronous orbit (SSO), followed by the four nano satellites - also called Cubesats, each weighing one kg. The remaining two, each weighing eight kg, were attached to the rocket's fourth stage. Of the six nano satellites, four are from Germany, one is from Switzerland and one from Turkey. The seventh is a big one, India's Oceansat-2 weighing 960 kg. Soon after the satellites were put into orbit, Indian Space Research Organisation's (ISRO) satellite tracking centres started monitoring them.
Seven satellites in 1,200 seconds. The launch is similar to the one in April 2008 when ISRO launched 10 satellites.
The sequence of ejection is very similar to the April 2008 launch featuring one big satellite - Cartosat-2A and nine other nano satellites - 10 in all: once the PSLV takes off and reaches a certain height and velocity, it will first launch the Oceansat-2 and a few seconds later, the first of four nano satellites. Every 10-12 seconds, the PSLV will launch four satellites one after the other. (Two will remain with the fourth stage).
"The rocket re-orients itself everytime a satellite is to be placed in orbit. The re-orientation ensures one satellite doesn't collide with another. The rocket effectively re-orients itself four to five times in the space of one flight," a scientist explained.
The brain of the rocket would have made all calculations in advance - from ejection of first satellite to the fifth. The exact moment of ejection and then re-orientation for the next ejection is worked out in advance. All mathematical calculations on the ground, launch sequence and flight path have to work to zero error. Oceansat-2, India's second satellite to study oceans as well as interaction of oceans and atmosphere, is the 16th remote sensing satellite of India. It is in the shape of a cuboid with two solar panels projecting from its sides. The satellite will map fishing zones around India, measure ocean surface windspeeds as well as atmospheric temperature and humidity.
This will be PSLV's 16th mission. From September 1993 to April 2009, PSLV has been launched 15 times. Fourteen launches have been successful continuously while only one has failed so far.
During 2007, the flight model OCM payload electronics was realised, the camera assembly was in progress and scatterometer configuration was finalised. Fabrication of mainframe systems like Core power, RF systems BMU, and sensors had started and DC-DC converters for OCM, earth sensor, TME realized.
As of 2008, mainframe structure had been realised. Preliminary design review of all mainframe systems completed. OCM camera test and evaluation had been completed. Scatterometer qualification model hardware had been realized. ROSA interfaces with spacecraft systems had been finalised. Qualification model of scatterometer scan mechanism and the interface test with electronics had also been completed.
The satellite was launched successfully on 23 September 2009

Yesterday we had a visit to Al Ain Zoo to see the animals, reptiles and birds. We saw a variety of deer, monkeys, snakes etc and tool some good photographs. The scene which I saw in the reptile park was quiet amazing. An iguana and tortoise in the same cage lives their as real friends. It was interesting tom see them staying together and communicating with their own textures.
Really a good example of natural love and friendship.

A person is able to lie by using his imagination. In the Narco Analysis Test, the person’s imagination is neutralized by making him semi-conscious. In this state, it becomes difficult for him /her to lie and his answers would be restricted to facts he is already aware of.
Experts inject the subject with Sodium Pentothal or Sodium Amytal (This is called ‘truth drug’). The person is not in a position to speak up on his own but can answer specific but simple questions during the test. The answers are believed to be spontaneous as a semi-conscious person is unable to manipulate the answers.
Interesting? So beware of! But don’t worry; this is used only for investigations, not for us. Result of this test also not fully accepted as solid evidences in the couts.

It was on the way back to Abu Dhabi after our vacation, I saw an article about Madam Fatima Obaid Al Jaber in the weekly abudhabiweek (www.abudhabiweek.ae) which my father picked up from the news stand in the air port. I'm well familiar of this name, my father used to speak about his COO (Chief Operating Officer) in many occasions and have seen news in the daily many times about her. She is definitely a role model of several enthusiastic women in the world and her success stories should be a learning subject for children. I would like to quote few things which made me a fan of her.
- She is Lady Graduate Engineer in Architectural Engineering
- She is the chief operating officer of the big Al Jaber group (www.aljaber.com)
- She honours many awards and chairs many initiatives, especially for women and engineering society.
Madam Fatima says:
"I love to work with people" - not only says, my father told, she implements this in the company.
"I want to expand my knowledge and develop relationships” - A good quality which anyone can adopt.
“Competition is not a bad thing. In fact it makes you work harder"
"Education is the key for the sociological change"
"I am passionate about my work. I try to learn from mistakes and build on the negatives with more positives"
I don't have another reason to elect her as my favourite personality this time.

An extrasolar planet, or exoplanet, is a planet beyond our Solar System, orbiting a star other than our Sun. As of 17 September 2009[update], 374 exoplanets are listed in the Extrasolar Planets Encyclopaedia. Extrasolar planets became a subject of scientific investigation in the mid-19th century.
On 16th September, 2009, a group of European astronomers said that they had found the first known rocky planet outside the solar system. The find by European Southern Observatory scientists in Garching, Germany, is an important step forward in answering the question of whether humans are alone in the universe, because it is the first of the more than 300 known exoplanets - as planets outside the solar system are known - that is not large and gaseous. CoRoT-7b has a density similar to Earth. Though the small exoplanet, CoRoT-7b, resembles Earth in many ways, it is far too hot to support life, This planet is about 500 light years from Earth!
Get more details from exoplanets.org. Wait and see, what next...
Ramadan is the ninth month of the Islamic calendar. It is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking, smoking, and indulging in anything that is in excess or ill-natured; from dawn until sunset. Fasting is meant to teach the Muslim patience, modesty and spirituality. Ramadan is a time for Muslims to fast for the sake of God , and to offer more prayer than usual. During Ramadan Muslims ask forgiveness for past sins, pray for guidance and help in refraining from everyday evils, and try to purify themselves through self-restraint and good deeds.
