I know I'm not the only one on the TweakTown staff that loves space. I also believe many of our readers happen to be space fans following Curiosity's journey on Mars. We now have three stunning panoramic images stitched together from over 60 raw images taken by the rover. These panoramas allow a wider field of view so you can get a better sense of where Curiosity is working.
Ken Kremer, creator of the panoramas:
I chose these scenes because they vividly tell the story of what NASA seeks to accomplish with Curiosity in the search for signs of life on Mars as well as tell the science story of the entire mission at a glance - one panorama is worth a thousand words, so to speak.
The images are stunning and really give a good idea of what the red planet's horizon looks like. In two of the three panoramas, Mount Sharp rises majestically in the background. This was done on purpose, according to Kremer, because it's "a dramatic backdrop as well as being the rover's ultimate destination."
Maybe these pictures will help encourage people to sign up to live in the Mars Colony.
The Solar Impulse is a plane powered completely by the sun. Its wings, which are the size of a Boeing 747's, are covered in solar panels which generate and store electricity in batteries so the plane can fly 24/7 without ever needing to stop to refuel. The plane is currently on a journey across the United States, with the first leg being from Mountain View, CA to Phoenix, AZ.
The first leg of the journey will take about 20 hours to complete due to the plane being rather slow moving. In fact, the plane only moves at around 40 MPH. You can track the Solar Impulse on its journey via the live stream and site set up by the creators. The stream shows a Google Earth view of the terrain below the plane, while the site has current speed, direction, temperature, engine settings, and battery status.
Happy Friday, everyone! Time to get your geek on. Google has released a new "Explorer Story" video in which a physics teacher heads 500 feet underground to tour the Large Hadron Collider, all the while teaching to a physics class thousands of miles away. How awesome!
The video really speaks for itself. But just in case it doesn't, Andrew Vanden Heuvel, the star of the video, has authored a blog post with his thoughts and experiences. I know that I can't wait to buy my own pair of Google Glass.
The video you are about to see was not created in CGI, nor does it use any of Hollywood's video trickery. Scientists at IBM's Almaden Research Lab in San Jose, CA, have figured out a way to precisely move and manipulate individual atoms in very precise ways. So precise, in fact, that they were able to film the world's smallest video using nothing but the building blocks of all matter.
When it comes to the things I love, the video above is about as high on the list as it gets. The simple fact that we have the technology to now take an individual atom and place it anywhere in space that we want is simply astounding, when you consider the fact that less than 100 years ago we had no idea that atoms even existed. To get a scale of what is going on here, each dot has been magnified about 100,000,000 times.
The video was made by using a scanning tunneling microscope that weighs as much as a full sized truck and operates at -268 degrees Celsius. The positioning of the atoms was achieved by moving a very tiny needle across the surface of a piece of copper the size of a postage stamp with a height from the surface of just one nanometer.
Everybody's favorite little rover, Curiosity, is back in contact with its handlers on Earth, now that Mars and Earth are in an alignment where communication is possible. Curiosity had previously been sitting mostly idle for the last four weeks while the sun blocked communications between Earth and Mars.
The first step NASA has to complete is to update Curiosity's software. After Curiosity is brought up to speed, its handlers will instruct the rover to continue analysis on Yellowknife Bay. Yellowknife Bay is the location that Curiosity has already found the basic building blocks of life.
We just didn't stumble into this area. This was something that took a lot of planning. In case something happened with the rover we needed to make sure we had science to do in that landing ellipse. What was serendipitous was landing in a past aqueous environment and finding sulfates and clays...The hope is we find some other examples of habitable environments. There are a bunch of different geological reasons why there could be more of less carbon in one place.
Eventually, scientists want Curiosity to climb up Mount Sharp.
Say we find something that looks like another attractive ancient potentially habitable environment and it's 200 meters above the base of Mount Sharp. We can go up there and then from there we can go not just upward but also downward again. So if you're looking for something, you can explore in both directions of time's arrow.
Researchers at Cern in Switzerland have some interesting things to play with, and have now proved the merits of a way to test antimatter as a source of the thing we all want to see in our futures: "anti-gravity".
Antimatter particles are the "mirror image" of normal matter, but have an opposite electric charge. Antimatter and its relationship with gravity is still a mystery, but it may just simple "fall up" rather than down. Researchers reporting in Nature Communications have made a few steps toward solving this notion.
Antimatter continues to be one of the biggest question marks in physics, where equal amounts of matter and antimatter should have been created at the Universe's beginning. But, if the two were to shake hands, they destroy each other in what is called annihilation, turning into pure light. Cern's Alpha experiment is here to help the researchers hopefully solve this.
It was just a week ago that applications opened up for Mars One, a manned one-way mission to Mars. Mars One is on the search for two men and two women from different nationalities on a one-way mission to the red planet in 2023.
After just a week, there have been over 20,000 applications with 600 applications coming in from China alone. Requirements for candidates are as follows: If you show resilience, adaptability, and curiosity, you might qualify. Scientific and astronaut's skills, however, are not required. In the last twelve months, 10,000 people from 100 different countries have expressed interest in the one-way ticket to Mars, with many applications coughing up the application fee submitting and sharing their one-minute videos which you can watch on the Mars One website.
NASA extends ISS crew transportation contract with Russians, says domestic flights not likely until 2017
In a disappointing announcement, NASA has said they have renewed a contract with Russia. The contract with Russia is for Rocosmos to transport US crews to the International Space Station and has been used since the space shuttle program was retired in 2011. The extended contract will cost NASA $424 million.
NASA believes they will be able to send up US crews in US ships sometime in 2017, as long as they get the funding proposed in Obama's 2014 budget.
NASA is committed to launching U.S. astronauts aboard domestic spacecraft as soon as possible. Full funding of the administration's Fiscal Year 2014 budget request is critical to making these domestic capabilities possible by 2017.
It's rather sad that the United States has to rely on our allies to send up our astronauts to space. Many good inventions have come out of the NASA space program and it's a shame to see funding cut.
NASA's Cassini probe sure is clocking up some serious frequent flier miles, but as the probe was circling Saturn for nine years, NASA's probe managed to capture some spectacular video of a gigantic storm on Saturn's north pole.
Our cyclones don't last anywhere near as long as this monster, which was spinning for several years, and at speeds that exceeded 300MPH. This cyclone is also locked to Saturn's north pole, and is fueled by small amounts of water vapor versus having an actual ocean to suck it up from. The hurricane's eye measures 1250 miles wide and is surrounded by fluffy white clouds that are the size of Texas.
Our readers seem to have quite an interest in space, and who wouldn't? As part of the commercialization of space and space travel, Virgin Galactic has successfully completed the first test flight of its space plane, which will eventually be used to take ordinary citizens into space.
Don't start packing your bags quite yet, though, as Virgin Galactic didn't even make it into space on this first test flight. The plane behaved as expected and flew for around 10 minutes before returning to the ground. It was shuttled to an altitude of 47,000 feet before being released to fly on its own.
After being released, the plane flew up to 55,000 feet and broke the sound barrier. Virgin Galactic expect to test the plane in space by the end of the year and plan to have real flights for everyone available starting in 2015.
Virgin Galactic Founder Sir Richard Branson:
The first powered flight of Virgin Spaceship Enterprise was without any doubt, our single most important flight test to date. For the first time, we were able to prove the key components of the system, fully integrated and in flight. Today's supersonic success opens the way for a rapid expansion of the spaceship's powered flight envelope, with a very realistic goal of full space flight by the year's end. We saw history in the making today and I couldn't be more proud of everyone involved.
