Water Vapour is supersaturated in Martian Atmosphere

Water Vapour is in Excess of Saturation in the Atmosphere of Mars,  reveals the results from the SPICAM spectrometer on board ESA's Mars Express spacecraft.
It measured the altitudinal profile of water vapour in the martian atmosphere.....

Here is the published paper:
"Evidence of Water Vapor in Excess of Saturation in the Atmosphere of Mars", by L. Maltagliati, F. Montmessin, A. Fedorova, O. Korablev, F. Forget, and J.-L. Bertaux, published in the 30 September 2011 issue of Science.

Faster than LIGHT ....? Questions Relativity...?

Recently, a group of physicists have been working to measure the neutrinos generated from a particle accelerator at CERN. This group discovered neutrinos arriving faster than would have been expected and they appear to be traveling faster than the speed of light itself, but they draw no definitive conclusions.

Aurora & Forest Fire - as seen from Space

I am sharing a beautiful video uploaded by NASA yesterday 26th Sep. in youtube.


It was a real observation from the International Space Station on 17th of this month.


First you see the beautiful 'Aurora Australis' and then you can see forest fires in land.


If you look more keen, you can see also the air-glow too....




You can find more information here.

Moon, Earth-Atmosphere as seen from Space

Earth's Moon
click image


Photographed by the Expedition 28 crew aboard the International Space Station, this image shows the moon, the Earth's only natural satellite, at center with the limb of Earth near the bottom transitioning into the orange-colored troposphere, the lowest and most dense portion of the Earth's atmosphere. The troposphere ends abruptly at the tropopause, which appears in the image as the sharp boundary between the orange- and blue-colored atmosphere. The silvery-blue noctilucent clouds extend far above the Earth's troposphere.

Seeing Equinoxes and Solstices from Space

This is how Solstice and Equinox look like .......
....... a wider perspective....
......view from space.

Equinox ------ Sun overhead equator ---- sunlight falls equally in both Hemispheres.
Solstice  ------ Sun is overhead northern/ southernmost position ---- sunlight falls maximum in Summer Hemispheres.


I have taken the selected days visible imagery from Meteosat and arranged them in a 2x2 matrix.....

Why should we travel to SPACE ....?

Why should humans go to Space ........?


                               Exploration is the inquisite nature of human mind, which has historically led to the discovery of new continents and development of new habitats. Looking back, without these discoveries and advances, living on Earth would have been completely different from what we see today. Rapid developments in human race, limitations in resources on Earth, and the potential threat from weapons of mass destruction necessitates that we will have to boldly go far beyond the Earth's boundaries if the human race has to continue for thousands of years forward. More importantly, space explorations hold the key to unravel the secrets behind the origin and evolution of life and environment surrounding us. These drive the quest for space exploration and colonization.


Where else can earthlings colonize?


                              Being close by and relatively easy to reach, our natural satellite 'Moon' comes as the first choice. Humans have already landed on it and conducted many surveys and studies based on remote sensing and insitu sampling. The discovery of the presence of water in the lunar surface and its extremely thin atmosphere by payloads in India's Chandrayaan-1 has further boosted the renewed interest in moon. Few unmanned lunar orbital missions are currently exploring the Moon (e.g., NASA's GRAIL) and several others are in the pipeline (e.g., ISRO's Chandrayaan-2, NASA's LADEE and ARTEMIS, JAXA's SELENE, ESA's Lunar Lander). In fact, moon can serve as an intermediate base for explorations beyond.
                            Mars is the second choice. Explorations startaed in the 1960s are still continuing. Studies revealed that there is significant quantity of water in the form of ice in the Martian poles. A colony on Mars could use this as a source of oxygen. In contrast, Mercury and Venus are too hot, while Jupiter and Saturn are gas giants with no solid surface and hence may not be suitable for colonization.

NASA Unveils Space Launch System

Artist concept of future destinations
NASA announced on 14 Sep 2011,development of the Space Launch System (SLS) -- an advanced heavy-lift launch vehicle that will help take human exploration beyond Earth's orbit.


The SLS rocket will use a liquid hydrogen and liquid oxygen propulsion system. 


Have a look at this animation and related links...

Oh No! A 6 Ton Satellite is falling back to earth....

A defunct Satellite ' The Upper Atmosphere Research Satellite, or UARS,  ' is falling back into earth... this month....!!

Where will it's impact be...?

Scientists say it's not likely to hit a populated place.... (statistics says so)

Though most of its parts would burn away .... still about 150 kg may reach to ground!!!!!

The satellite is so big, its plunge through the atmosphere will be visible -- if anyone is around to see it.

WATCH  for it above your head..!!

Lasers can Trigger Rain formation...?

Scientists made a breakthrough! In their paper published in Nature Communications, they describe a method whereby a laser is used to create nitric acid particles in the air to which moisture will gravitate forming droplets.
Thereby triggering the formation of Rain.

 Field measurements suggest the mechanism of laser-assisted water condensation, Nature Communications 2, Article number: 456doi:10.1038/ncomms1462
