After the Moon and Mars, ISRO eyes Venus for next exploration mission


earth-2

After the successful launch of its Mars orbiter, the Indian Space Research Organisation (ISRO) is now viewing Venus as possibly the next planet it can study and explore.

“Besides the Mars-2 mission, we are looking at Venus and even an asteroid for exploration. A project has to be formulated for this before we chart out a proper roadmap for the explorations.  Venus is our neighbour and has many scientific challenges and aspects that need to be studied. Exploring an asteroid is also challenging task,” Dr Kiran Kumar, Isro chairman, told HT.

In 2014, India created history in space when its Mars orbiter slipped into the Red Planet’s orbit in its maiden attempt.

India became the first Asian country to reach Mars and the first in the world to enter the orbit of the planet in its first attempt.

Regarding the Saarc satellite, Dr Kumar said that it would be launched before December 2016. “The activities related to this project are in progress and we should begin building the satellite soon.”

Moving beyond satellite launches and planetary explorations, Isro is also aggressively working with many government departments on optimising the usage of space tools and data.

A national meet on space is likely to be held in Delhi next month, where ministries and departments of the government will give presentations on how they are using space tools in their workings. From civil aviation to railways, tribal affairs to health, postal to agriculture the number of government departments working with Isro has increased to more than 60 in the past few months.

The New Horizons Pluto mission is a big deal. Here are Some reasons why


SOURCE : vox.com 

NASA’s New Horizons spacecraft is about to show us an alien world for the first time. At precisely 7:49 am ET on Tuesday, the probe will become the first spacecraft to fly by Pluto.

New Horizons has been en route for nine years, traveling more than 3 billion miles. The flyby will be over in a matter of minutes, as the probe frantically takes hundreds of photos and collects data on Pluto’s atmosphere, geology, and moons. All this data will be enormously valuable to scientists as they seek to understand our solar system and how it formed billions of years ago.

More than anything, this mission is about broadening our horizons — taking in just a little bit more of the impossibly vast universe we live in.

1) We’ve never seen Pluto before

Pluto feels familiar. It’s easy to imagine the small, frigid rock, millions of miles from the sun and covered in ice.

But what you’re picturing in your head when you think about Pluto is probably an artist’s illustration. Until very recently, we didn’t even know exactly what color it was — and the best photos we had of Pluto looked like this:

pluto-hubble

New Horizons is going to change that in a very big way. Already, as it’s closed in on Pluto, it’s given us way better photos than ever before:

The high-resolution photos to come will give us detailed topographical maps, just like those provided by the satellites that orbit Earth. They could reveal mountains, ice caps, volcanoes, or even an ocean of liquid water under the ice. “Who knows what kind of bizarre things we’ll find up close?” Stern said.

2) This mission will remind you how vast space really is

Pale-Blue-Dot

Earth, as seen by the Voyager spacecraft, from more than 4 billion miles away.

We spend our entire lives on the surface of Earth — so it’s hard to really grasp how far away Pluto truly is from us.

But as an analogy, think of Earth as a basketball. By comparison, Pluto would be a little larger than a golf ball. But if you wanted to keep the scale constant, you’d have to put that golf ball incredibly far away: 50 to 80 miles (depending on its location in orbit). This mission, like many activities in space, is a good reminder of how vast our corner of the universe is — and how absurdly tiny our entire earthly realm of experience is by comparison.

And it’s not just the size of space that boggles the mind. It’s also the timescale on which everything occurs. Pluto takes 248 Earth years to orbit the sun. To put it another way, the entirety of US history has occurred during a single Plutonian orbit.

3) We won’t get many more missions like this for a while

europa

There’s a mission to Europa planned, but it won’t reach the moon for a decade or more.

The past few decades have been filled with all sorts of fascinating missions to the planets, moons, asteroids, and comets of our solar system — uncrewed probes sent every few years, run by trained scientists, and supported by government funding.

But the sad truth is that this era is largely drawing to a close. As David W. Brown writes in an article on the dark future of American space exploration, “There is nothing budgeted in the pipeline to take its place. Yesterday invested in today. But we are not investing in tomorrow.”

This is the result of cutbacks to NASA’s planetary exploration budget. The OSIRIS-REx probe will launch next year, to travel to an asteroid and bring back a sample, but it won’t return until 2023. Meanwhile, a mission to Jupiter’s moon Europa is in the works, but it likely won’t be launched until 2025 at the earliest, and wouldn’t reach Europa until the 2030s.

In other words: Enjoy this brief flyby. It’s going to be a while before any NASA probe visits a new world.

4)This is a staggering technological achievement

t’s hard to appreciate just how difficult it is to send a spacecraft to Pluto. But think of it this way: because it’s so incredibly far away, it took New Horizons nine years to cover the 3-billion-mile trip there — which means the craft is using decade-old technology, traveling a route that was calculated years ago.

Screen_Shot_2015-07-09_at_9.53.45_AM.0

New Horizons’ trajectory through the solar system.

Despite this, NASA engineers managed to get the tiny probe — about the size and shape of a grand piano — to an incredibly precise spot in space, using Jupiter’s gravity as a slingshot to accelerate it outward and a few thruster burns over the years to keep the probe on track.

Along the way, they had to worry about potentially damaging debris nearby Pluto — as well as a scary software glitch this past weekend, which was, thankfully, resolved. Now New Horizons is going to fly within 7,750 miles of Pluto, coming closer than its moons.

Because New Horizons is traveling at such a high speed (about 31,000 miles per hour) and can’t slow down, the flyby will be over in a matter of minutes — fording it to collect all its data in a tiny window of time.

And receiving all that data is another huge challenge. Because New Horizons is so far away, it takes about 4.5 hours for any data it sends back to reach Earth. And the signal is so faint that NASA has to use 200-foot-wide radio dishes (one each in Australia, California, and Spain) to pick it up. This means an extremely low rate of data transmission: about 1 kilobit per second, more than 50 times slower than a 56k modem from the ’90s. It takes more than 42 minutes for New Horizons to fully transmit an image that’s 1024 pixels wide.

If you haven’t been paying attention so far, now’s the time to start. This is a really big deal.

NASA to Send Microsoft’s Virtual Reality Headset to International Space Station


NASA is sending Microsoft’s virtual reality headset to the International Space Station (ISS) to beam back to Earth what astronauts see in space.

NASA and Microsoft are teaming up to develop Sidekick, a new project using commercial technology to empower astronauts aboard the ISS.

Sidekick uses Microsoft HoloLens to provide virtual aid to astronauts working off the Earth.

A pair of the devices is scheduled to launch on SpaceX’s seventh commercial resupply mission to the station on June 28.

“HoloLens and other virtual and mixed reality devices are cutting edge technologies that could help drive future exploration and provide new capabilities to the men and women conducting critical science on the International Space Station,” said Sam Scimemi, director of the ISS programme at NASA Headquarters in Washington.

“This new technology could also empower future explorers requiring greater autonomy on the journey to Mars,” said Mr Scimemi.

The goal of Sidekick is to enable station crews with assistance when and where they need it. This new capability could reduce crew training requirements and increase the efficiency at which astronauts can work in space.

“Sidekick is a prime example of an application for which we envisioned HoloLens being used – unlocking new potential for astronauts and giving us all a new perspective on what is possible with holographic computing,” said Alex Kipman, technical fellow, Windows and Devices Group at Microsoft.

NASA and Microsoft engineers tested Project Sidekick and the Microsoft HoloLens aboard NASA’s Weightless Wonder C9 jet to ensure they function as expected in free-fall in advance of their delivery to the microgravity environment of the space station.

Sidekick has two modes of operation. The first is “Remote Expert Mode,” which uses Skype to allow a ground operator to see what a crew member sees, provide real-time guidance, and draw annotations into the crew member’s environment to coach him or her through a task.

Until now, crew members have relied on written and voice instructions when performing complex repair tasks or experiments.

The second mode is “Procedure Mode,” which augments standalone procedures with animated holographic illustrations displayed on top of the objects with which the crew is interacting.

This capability could lessen the amount of training that future crews will require and could be an invaluable resource for missions deep into our solar system, where communication delays complicate difficult operations.

Dwarf planet Ceres reveals pyramid-shaped mystery


Image of Pyramid taken by NASA’s Spacecraft DAWN. Do you think it is just a simple mountain or Something else.
OK, this is just too much.

First, NASA’s Dawn probe spotted curiously sparkly bright spots on the surface of Ceres, the dwarf planet that lies in the asteroid belt between Mars and Jupiter.
Beats us, the scientists said.

Now, cameras on the tractor-trailer-size spacecraft have captured a baffling structure rising 3 miles above the planet’s cratered surface.

Conveniently, the thing looks an awful lot like a pyramid.”Intriguing,” the NASA scientists said.

 Another Image of Ceres showing Strange mysterious lights. Image taken by NASA’s DAWN spacecraft.
To be fair, the agency offered no suggestion that the towering structure is an offering to some long-lost space emperor or home to our new alien overlords.
And, to be even more fair, it’s probably just a really tall mountain in a solar system filled with wondrous and strange natural phenomena.

But the Dawn mission has done nothing but stoke imaginations since the discovery of mysterious bright spots on the surface of the dwarf planet in February and the beginning of the probe’s orbit in March.

Folks have claimed to have spotted giant alien motherships hovering over the planet, bat-winged spaceships parked on its surface and even evidence of alien cities.

But the mystery only deepened with the most recent batch of images showing even more bright spots alongside the largest one, which NASA said looks to stretch some 6 miles.

Many, of course, insist that the spots look for all the world like brightly lit cities twinkling on the shadowed surface of the distant dwarf planet.

I knew it! There’s gambling going on on Ceres! #aliens pic.twitter.com/QP6PB6JFho

 
— Chris Reher (@Chris_Reher) June 13, 2015
Of course, NASA hasn’t traveled down that road. Scientists, they say, still don’t know what the spots are. Maybe ice. Maybe salt.
“But scientists are considering other options, too,” NASA said coyly.
But #itsaliens, right?

Artistic Depiction of Pluto 

The National Space Society put together an incredible video preview of the history-making moment. It has the vibe of a movie trailer, complete with epic narration and stunning visuals, and it perfectly captures why space enthusiasts are so psyched about the New Horizons mission.

The video sweeps you through a timeline of the last half century of space exploration using beautiful images of each planet we’ve explored, starting with Venus in 1962 and ending with Neptune in 1989.

New Horizons will reach Pluto and its moons on July 14, and they will be “the farthest worlds ever to be explored by humankind,” the video says.

So far that the sun appears as a faint dot.

NASA’s Dawn Probe Sees Dwarf Planet Ceres as a Crescent


284735main_A-DualAsteroidBelts-full

After spending several weeks in the shadow of Ceres, NASA’s Dawn spacecraft is finally getting a close-up glimpse of the dwarf planet.

For Those Who Don’t Know About CERES : Ceres is the largest object in the asteroid belt, which lies between the orbits of Mars and Jupiter. It is composed of rock and ice, is 950 kilometers (590 miles) in diameter, and comprises approximately one third of the mass of the asteroid belt. It is the only dwarf planet in the inner Solar System and the only object in the asteroid belt known to be unambiguously rounded by its own gravity.

Ceres’ cratered north pole blazes through the darkness in new images captured by Dawn on April 10. The photos are the highest-resolution views of the world that Dawn has gotten since entering Ceres’ orbit on March 6, NASA officials said.

150417-ceres_72b30c3767d128d8e23407c0516ae9f0.nbcnews-ux-1440-800

Dawn was about 21,000 miles (33,000 kilometers) from the dwarf planet when the pictures were taken, and mission team members promise even better views of Ceres in the months to come.

Full science observations begin April 23, when lighting conditions will be better for Dawn and the probe will be even closer to Ceres — just 8,400 miles (13,500 kilometers) above the surface. Dawn will begin moving even lower down on May 9.

In future weeks, NASA hopes the mission will help scientists better understand a key mystery of Ceres: strange bright spots on its surface that, in some cases, have different temperatures than the terrain surrounding them. Mission scientists still don’t know what the spots are made of.

The $466 million Dawn mission, which launched in September 2007, aims to better characterize the solar system’s early days by studying Ceres and Vesta, two intact protoplanets that are the largest denizens of the asteroid belt between Mars and Jupiter. The probe spent 14 months at the 330-mile-wide (530-kilometer-wide) Vesta in 2011 and 2012, then headed to Ceres.

Mission scientists said they expect that Ceres, which is about 590 miles (950 km) wide, will be wetter than Vesta, and made of different stuff. Some researchers think Ceres may even harbor liquid water beneath its surface, perhaps making the dwarf planet capable of hosting life as we know it.

Ceres: NASA Finds Mysterious White Spot On Dwarf Planet

NASA scientists have been stymied by the discovery of a large, bright white spot on the dwarf planet Ceres, which has been revealed in images from the Dawn spacecraft, set to soon arrive at the unusual celestial object.

Ceres-670-665x385

The white spot appeared in a series of photographs of Ceres taken on January 13, according to Space.com. Though the images were released on January 19, just what has caused the anomaly on the dwarf planet, which is located between Mars and Jupiter in the asteroid belt, remains undetermined, according to mission director and chief engineer Marc Rayman.

“Yes, we can confirm that it is something on Ceres that reflects more sunlight, but what that is remains a mystery,” he said.

The Dawn spacecraft marks the first mission to Ceres, and is set to arrive at the dwarf planet in March of this year. The spacecraft has traveled 3.1 billion miles over the last seven years, according to Popular Science, pushed toward the asteroid belt at just 450 mph by a set of ion thrusters.

Scientists know precious little about Ceres, which has a diameter of 590 miles and a surface area four times larger than the state of Texas. Astronomers have previously observed water vapor plumes erupting off Ceres, thought to be the product of ice geysers referred to as “cryovolcanos.” Though much of its mass is believed to be composed of water, some speculate that the Dawn mission will determine that the dwarf planet possesses a rocky, barren surface.

Although it is unclear what Dawn will find when it reaches the dwarf planet, the spacecraft already has a mystery to solve in the form of Ceres’ unusual white spot.

Giant Asteroid Is Headed Our Way, But NASA Says No Worries

A ginormous asteroid is headed our way, but no need to worry. NASA says asteroid 2004 BL86–estimated to be about one-third of a mile in diameter–will zoom harmlessly by Earth later this month.

That’s good news, of course. And get this: The asteroid’s size and proximity–about 745,000 miles from Earth at the nearest point in its flyby, or about three times the distance from the Earth to the Moon–mean it should be visible with nothing more than a good pair of binoculars.

nearearthasteroid

“Monday, January 26 will be the closest asteroid 2004 BL86 will get to Earth for at least the next 200 years,” Don Yeomans, manager of NASA’s Near Earth Object Program Office at the Jet Propulsion Lab, said in a written statement. “And while it poses no threat to Earth for the foreseeable future, it’s a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more.”

Skywatchers in the Americas, Europe, and Africa should have the best view of the asteroid on the night of Jan. 26, according to EarthSky. Weather permitting, the asteroid should be visible moving slowly across the sky in the vicinity of the constellation Cancer.

Of course, it will only look slow. The asteroid is actually streaking at about 35,000 miles an hour.

Yeomans said he might grab his own binoculars and have a look himself. If you’d rather stay indoors, you can catch the action online at The Virtual Telescope Project 2.0. The show starts at 2:30 p.m. EST.

A Pair of Black Holes Could Soon Collide And Destroy Their Galaxy


latest

One black hole is not to be messed with, let alone two. Astronomers have discovered what appears to be two supermassive black holes just one light-year apart, setting up a collision so massive it could be release as much energy as 100 million supernovas and destroy it’s inside galaxy . Yep.

A Supermassive Black Hole is the largest type of black hole, on the order of hundreds of thousands to billions of solar masses and are found in the center of almost all massive galaxies.In the case of the Milky Way, the Supermassive black hole is believed to correspond with the location of Sagittarius A*(At the center).

Thankfully, the black holes are far away in a remote galaxy called PG 1302-102. The collision itself, if astronomers have done the calculations right, will happen in the next million years. That’s a pretty unfathomably long time for humans, but just a blink of an eye in cosmic time.

Astronomers are excited about the discovery because a pair of black holes could yield valuable information about theorized but never directly detected gravitational waves. Gravitational waves are ripples in space-time that exist according to Einstein’s theory of general relativity. If the two black holes collide, most of the released energy will be in the form of gravitational waves, literally bending the fabric of space-time.

But for now, the pair of black holes still need to be 100 percent confirmed. When two black holes so far away are close to one another, astronomers on Earth can only see it as a particular flicker of light. Astronomers need to rule the flicker out as a statistical anomaly. Still, in the long history of the universe, black holes have almost certainly collided before. Destroying whole galaxies in one fell swoop is not just science fiction.
