As space exploration becomesdemocratized, the entry price for such endeavors has fallen dramatically. One company taking advantage of this is Pocket Spacecraft, a Bristol-based enterprise that thinks it can send thousands of personalized probes to the heavens for a few hundred dollars apiece. While it may look more like a used coffee filter, the Earth Scout / Lunar Scout is a CD-sized, paper-thin probe that contains a bonded solar cell, system-on-a-chip and antennas. Several thousand of these will be loaded onto a CubeSat and then dropped onto Earth or the Moon, depending on your project and contribution. Users who cough up the cash will then be able to observe how thin, papery probes journey downward, with telemetry being sent to an Android / iOS app. Anyone interested in backing the project on Kickstarter should check out the video after the break and then empty their savings of £99 ($150) to buy an Earth scout or £199 ($302) if they intend to explore the Moon.
A couple of days ago, an story started making the rounds that suggested the NASA spacecraft Voyager 1 had left our solar system and headed into interstellar space. Leaving our solar system would make Voyager 1 the first man-made spacecraft ever to exit our solar system.
The tip that the spacecraft had left our solar system came from an American Geophysical Union report. However, NASA is now saying that the consensus of the Voyager science team is that Voyager 1 has not yet left. The confusion comes in the fact that increasing radiation led some scientists to believe that Voyager 1 had left our solar system’s Heliosphere. However, Voyager project scientist Ed Stone disagrees.
Stone says that Voyager 1 has simply reached a new region of the Heliosphere called “The Magnetic Highway” where energetic particles change dramatically. Stone says that a change in the direction of the magnetic field is the last critical indicator of reaching interstellar space and that change has not yet occurred. It’s amazing that we are still getting data from a spacecraft launched in 1977. Another amazing fact about the Voyager 1 is that while it was launched in more than 35 years ago, so far it has only traveled approximately 34 light hours and 13 light minutes away from the Earth at the time of writing.
NASA's Curiosity rover has mostly had smooth sailing since it touched down on Mars last year. Unfortunately, it's in a more precarious position as of this past Thursday. After noticing corrupted memory files on the robot's primary computer, overseers have kicked Curiosity into a "safe mode" with a backup computer while they determine what's wrong and deliver any viable fixes. Don't think of this like you would the Safe Mode on a Windows PC, though. While the backup can serve as a replacement for the main computer, project manager Richard Cook warns Space.com that it will likely take "several days" to supply enough information that the failsafe can take over. NASA will switch back to the main computer if and when it's ready; if it is, the agency hopes to harden the code against future flaws. Curiosity will effectively stay on ice in the meantime... and not the variety it might want to find.
It's hard to deny the appeal of a space-bound robot like NASA's Robonaut 2, fears of subversion notwithstanding. The space agency and Florida's Institute for Human and Machine Cognition know it, and they want to put that technology into an exoskeleton with a nobler purpose than performing chores on space stations. The in-development X1 (not yet pictured) adapts the Robonaut's skills to a body-hugging frame with 10 points of movement that might give humans an assist when they need it the most. In space, the X1 could automate and add challenge to exercise for astronauts in low gravity, or provide the extra muscle for that fabled day we return to manned surface exploration. NASA envisions its exoskeleton having more grounded uses as well, such as rehabilitation for leg injuries or walking for those who never had the chance. Although we're not expecting a rapid turnaround knowing NASA's lengthy schedules, we might see the X1 in use sooner than most such products in the wake of a purposefully quick development cycle -- and, no doubt, a few interested customers here on Earth.
As NASA promised, Curiosity has stopped at the quarter pole toward its first scientific destination to test its robotic arm and attached scientific instruments. After 100 yards of driving, the rover extended its 7-foot limb, and will now spend six to ten days checking its predetermined positions and range of motion. That will ensure the appendage is ready after surviving the chilly vaccuum of space and subsequent setdown, and will let its minders see how it functions in the unfamiliar Martian gravity and temperatures. The JPL scientists in charge of the six-wheeler will also peep the Mars Hand Lens Imager and made-in-Canada Alpha Particle X-Ray Spectrometer to warrant that they're up for all the geology to come. If all goes well, the rover will start scooping, drilling and analyzing in earnest when it hits Glenelg, then Mount Sharp -- so, we'd limber up first before tackling all that, too.
It's hard to believe at times that the Voyager 1 probe is older than many of us reading this article, but it's true. The official first part of NASA's Voyager program launched just over 35 years ago on September 5th, 1977, carrying not just cameras and sensors to capture the trip but the famous Golden Record documenting humanity for any curious aliens. To mark the occasion, Wired has gathered together one heck of a photo album that covers both Voyager 1's trip as well as that of Voyager 2, which technically launched earlier (August 20th the same year) but took a more roundabout route through the solar system. The gallery reminds us of the amazing scenery beyond Mars and puts our tiny blue ball of a planet in perspective; Earth was just a speck at best when photographed late into Voyager 2's journey. Perhaps the best news surrounding the milestone is simply that both Voyager probes are still running. At 11 billion miles from the Sun, Voyager 1 may be on the cusp of interstellar space and easily represents the most distant human object ever made, not to mention a record-setter for signal transmissions. There's even a chance we'll still be hearing back from the probe for its 50th anniversary -- its power could keep it chatting up to roughly 2025.
Now that Curiosity has survived its thrill-a-minute landing and passed an upgrade and physical with (nearly) flying colors, the rover is off to earn its $2 billion keep. The buggy got off to a good start, driving 52 feet towards its first science site "beautifully, just as our rover planners designed it," according to NASA. The destination, Glenelg, is 1,500 feet away from the now-familiar Bradbury Landing where it first set down, which is pretty far for a rover that treks along at about a tenth of a mile per hour. On top of that, its minders have some stops in mind to test instruments -- meaning it'll arrive there in about two weeks. Once at Glenelg, Curiousity will scope the unusual geology of the region, though its principal destination for science is Mount Sharp, a relatively vast six miles away. Don't worry about it running out of gas, though -- it's nuclear power supply will last a full Martian year, or 687 earth days.
As the vista on Mars gradually gets ever clearer, and the system checks continue to show that the rover is in good stead, the team behind Curiosity will be increasingly eager to stretch its legs wheels. The first trip might be just a cautious few meters, but plans for a more adventurous jaunt have just been revealed. The first location in Curiosity's sights is an area referred to as Glenelg, which, based on initial pictures, offers three different geological characteristics, as well as potentially being an area where water used to be present. The site is only 1,300 feet (400 meters) from where the rover landed, but it could still take several weeks to get there. This is merely a quick dash compared to the next leg of its journey, which sees Curiosity heading out to an area called Mount Sharp -- a large mound of layered rock which is hoped to contain visible geology potentially dating back millions of years. With seven kilometers (4.4 miles) lying between the rover and the mountain's foothills, it'll be a much longer journey, but one that could provide the first real evidence of the planet's ability to host, or have hosted, life.
There a lot of things I’ve always wanted to see around the world, but I’ll probably never get a chance to actually go to. Most of the stuff that I really want to see here are things like the Colosseum in Rome, Stonehenge, and the leaning Tower of Pisa to name a few. Google has a new project that will let you virtually explore many of the wonders of the world from your living room.
Google has launched its World Wonders Project that uses their Street View technology to give people the ability to explore many of the world’s greatest landmarks virtually. The project offers a glimpse at the details of 132 ancient and cultural sites across 18 different countries. In addition to the Street View, the website includes 3D models for many locations using Google Earth.
The sites include places such as Stonehenge, archaeological areas of Pompeii, to ancient temples in Japan. Google says that it couldn’t drive its typical Street View cars up to these monuments so it used trikes that pedaled up to the monuments. In some instances, you can get closer using Google’s new service then you can actually visiting the locations in person. For instance, Google was able to go in between the stones at Stonehenge, which has been off-limits for 35 years.
