Cassini’s findings puzzle ring scientists; Relatively dust free gap between Saturn and its rings
Sowmya Seshadri -0
Cassini's Grand Finale findings puzzles several scientists. The narrow gap region between Saturn and its rings, appears to be dust-free.
The relatively dust-free gap has broken down the basic assumption. The assumption of a dustier environment in the gap lead to the spacecraft's saucer-shaped main antenna. Cassini team created it to act as a shield during most future dives through the...
Cassini has always kept the space and astronomy world busy by exploring the unexplored parts of Saturn. The space craft will soon end its voyage.
NASA's Cassini spacecraft will make its first dive through the narrow gap between Saturn and its rings on April 26, 2017. The gap, unexplored so far, poses a great challenge to the spacecraft and the...
NASA’s Cassini spacecraft faces one last critical and risky adventure around Saturn.
Cassini swings past Saturn's mega moon Titan early Saturday for a gravity-assisted, orbit-tweaking nudge.
Cassini’s fuel tank is practically empty, so with little left to lose, NASA has opted for a risky, but science-rich grand finale.
“That last kiss goodbye,” as project manager Earl Maize calls it, will push Cassini...
A team of scientists at NASA have blended the essence of fashion and engineering to produce a new fabric for use in space.
These fabrics can be used for antennas and other deployable devices. This fabric material is foldable and changes its shape quickly. They can also help shield a spacecraft from meteorites. Other uses of this fabric include, astronaut...

A giant asteroid to fly past Earth on April 19; NASA confirms “no collision”
Sowmya Seshadri -
On April 19, a relatively large near-Earth asteroid will fly past safely. Scientists have made it clear that there is no possibility for it to collide with our planet.
The asteroid, 2014 JO25, discovered in May 2014, will fly past at a distance on 1.8 million kilometers. This is approximately 4.6 times the distance between Earth and the moon. Anyhow,...

April feast for star-gazers; Jupiter visit, Lyrids meteor shower and much more
Sowmya Seshadri -
For star-gazers around the world, this month will be a small, but a great treat. Our giant relative will put on a good show throughout the month.
One can view Jupiter all night long. On April 7, it reaches opposition. It will shine the brightest and will appear larger than usual. The solar system is lined up so that Jupiter,...

Comet 41P to pass closer to Earth than it normally does; Will make its closest approach to the sun on April 12
Sowmya Seshadri -
A big treat awaits for comet hunters as comet 41P visits after a very long time. On April 1, 2017, comet 41P will pass closer than it normally does to Earth.
For observers with binoculars its a special viewing opportunity. Observers can see it near the constellations Draco and Ursa Major. In 1973, the comet put on a spectacular show. The comet, if experiences...

Space Station Astronaut Peggy Whitson gears up to break spacewalk record today
Roopa Kanthraj -
Expedition 50 Flight Engineer Peggy Whitson is set to go on her eighth spacewalk Thursday morning and surpass astronaut Suni Williams record for the most spacewalks by a female astronaut.
Astronaut Peggy Whitson, 56, holds a doctorate in biochemistry. She is America’s most experienced female astronaut, veteran of two long-duration stays aboard the station in 2002 and 2007-08 totaling nearly 377...
