Use It Wisely


We might think our efforts to preserve God’s world aren’t valuable.  But we can all work together to do our part.  Buying and consuming less, repairing instead of replacing it, recycling, reusing, and simplifying are all the best stewardship practices. 
One way we can testify of our love for God and to express our gratitude for what He has done is by tending and keeping the earth and all that it offers.  Until God returns, let’s use our world wisely.

God’s Grace

Life is so full of meaning and purpose, so full of beauty, beneath its covering, that you will find that earth but cloaks your heaven. – Fra Giovanni

NASA signs agreement with ISRO for use of Indian satellite

Good morning friends.  NASA signs an agreement with Indian Space Research Organization for the use of Indian Satellite.

US space agency NASA has signed an agreement with ISRO to use data from Indian satellite Oceansat-2, for various American agencies for research activities, including weather forecasting.

Launched on September 23, 2009 using the Polar Satellite Launch Vehicle from Sriharikota, Oceansat-2; is designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on Oceansat-1.

The agreement with the Indian Space Research Organization will lead to the use of data from Oceansat-2 for various US agencies for research, education and other activities of public good including weather forecasting.

The Letter of Intent in this regard was signed by Michael H Freilich, Director Earth Science Division, National Aeronautics and Space Administration; Mary E Kicza Assistant Administrator for Satellite and Information Science of the Oceanic and Atmospheric Administration; and R R Navalgund, Director, Space Application Centre, ISRO.

The signing ceremony was done in Washington on the sidelines of Sixth Plenary Session of the Group on Earth Observations (GEO).

The Deputy Chief of Mission, Indian Embassy, Arun K Singh; and Deviprasad Karnik, Counselor (Space) were also present on the occasion.

The Letter of Intent signed between ISRO, NASA and NOAA under the overall Joint Civil Space Cooperation agreement promotes opportunity for receiving Oceansat-2 data by the US agencies for research, education and activities of public good.

The joint activities would include calibration, validation, algorithm development, scientific investigations and operational applications.

While ocean colour data is envisaged to be useful for fisheries, monitoring of harmful algae and in studying global carbon cycles, wind vectors from scatterometer would be useful in facilitating better weather forecasting.

Oceansat-2 carries three instruments like the eight band Ocean Color Monitor (OCM) to study Ocean biology, Ku band pencil beam Scatterometer to measure sea surface wind vectors and Radio Occultation Sounder for Atmosphere (ROSA).

While the first two instruments are ISRO built, ROSA has been contributed by the Italian Space Agency.

All the three payloads have been switched on and are working satisfactorily, providing valuable data, said a statement from the Indian Embassy. Indian Express

India successfully launches spy satellite RISAT -2

Good morning friends.  I read one article with reference to NDTV.  Indian was successfully launches a spy satellite RISAT-2.


Aiming to bolster India’s defence surveillance capabilities, ISRO on Monday successfully launched its first all-weather spy satellite that will help security agencies keep a watch on the movements on the borders, from its spaceport.

The PSLV-C12, carrying 300-kg Radar Imaging Satellite (RISAT-2) and 40-kg micro educational satellite ANUSAT lifted off from ISRO’s Satish Dhawan space Centre here at 6:45 am and placed into 550 km orbit around earth.

The Polar Satellite Launch Vehicle, weighing 230 tonnes at the time of launch, soared into a clear sky from the spaceport here, about 90 km north of Chennai.

At the end of the 48-hour countdown, the 44-meter tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

RISAT has all-weather capability to take images of the Earth and would also be beneficial in mapping and managing natural disasters, such as floods and landslides, besides amplifying defence surveillance capabilities of the nation. It would also help keep track of ships at seat that could pose a threat.

As per specifications, RISAT is different from previous remote sensing satellites as it uses Synthetic Aperture Radar (SAR), equipped with many antennas to receive signals that are processed into high-resolution pictures.

The SAR, developed by Israel Aerospace Industries, gives RISAT defence capabilities.

ANUSAT is the first satellite developed by an Indian university (Anna University), which would demonstrate the technologies related to message storing and forward operations.

University sources said scores of students and faculty from different streams had worked on this satellite for the last six years.

ANUSAT is a store-and-forward communication satellite that will help transfer confidential academic materials, including exam question papers, to prevent question paper leakages. It will also help monitor drought and wasteland, urban planning and other studies.

This is the 15th flight of ISRO’s workhorse PSLV, which had launched 30 satellites (14 for India and 16 for foreign countries) into a variety of orbits since 1993.

Delhi, Mumbai to ‘switch off’ to save the planet

Good morning friends.  I’m reading some new when I came across with this article.  It’s good to hear that something can be done to save our planet.  When I was in my high school days this is my favorite topic to talk about.  That’s why when I saw this news, I read it.  I want to share it with you.


It has been said that for an hour on March 28, Delhi will join in on giving the Earth a rest. Delhi is part of a 371 city initiative which will see cities switching off their lights completely for an hour at 8.30 pm IST.

The initiative, called Earth Hour, is by WWF International and seeks to raise awareness on the pressures on the planet today and the looming spectre of climate change as a result of high energy consumption.

Even as there have been similar ‘switching off’ initiatives in the past, this is set to be the largest and most far reaching initiative to raise awareness on pressures on the planet, with some of the greatest, and most energy intensive cities taking part.

This consists of  37 national capitals and other great metropolitan hubs like London, Paris, Beijing, Rome, Moscow, Los Angeles, Rio de Janeiro, Hong Kong, Dubai, Singapore, Athens, Buenos Aires, Toronto, Sydney, Mexico City, Istanbul, Copenhagen, Manila, Las Vegas, Brussels, Cape Town and Helsinki besides New Delhi and Mumbai.

Shooting Star

If you look up at the sky on a clear night, you may see a “shooting star” flash across the sky.  Shooting stars are bits of space matter called “meteors”.  Most are no bigger than grains of sand.  Billions of meteors zip through space.  Many are captured by earth’s gravity, and are pulled toward earth.  As the meteors whiz through the earth’s atmosphere, friction causes them to burn white hot.  Then we see them as blazing traits of light.  Meteors usually burns up long before reaching the ground.  Those that survive their fall and land on earth are called “meteorites.”
