Mars Stereo View from 'John Klein' to Mount Sharp. Credit: NASA/JPL-Caltech.
Above is a recent 3-D version of a panoramic view from NASA of the Curiosity Mars rover, made from dozens of images from both the left and right Navcams. But panoramic specialist John O’Connor has also put together a non-3-D interactive view of this scene of the rover and its surroundings. The images were taken during the 166th, 168th and 169th Martian days, or sols, of Curiosity’s work on Mars, which equates to Jan. 23, 25 and 26, 2013 here on Earth.
Check out the interactive panorama here, or below. It will probably come up as full-screen, and you can use your mouse to interact and move around. Or just hit ‘escape’ if you’d rather not be in full-screen mode. You can still use the mouse to move around wherever you want to go, or use the toolbar on the lower left for more options. This is a high-def view so feel free to zoom in for details!

We haven’t heard much from Curiosity lately because Mars is still in solar conjunction, where Mars and Earth are on opposite sides of the Sun from each other, meaning communications are basically worthless between the two planets. Our powerful Sun interrupts radio transmissions between Earth and the Mars rovers and orbiters, and data to and from the spacecraft might get corrupted. So, to avoid any problems, the spacecraft (and spacecraft engineers and scientists) take a little time off; the solar conjunction serves as a little spring break. But things should be back at full-throttle by next week.
For the 3-D view above (click on it to see a larger view), use red-blue glasses with the red lens on the left. It spans 360 degrees, with Mount Sharp on the southern horizon.
In the center foreground, the rover’s arm holds the tool turret above a target called “Wernecke” on the “John Klein” patch of pale-veined mudstone. On Sol 169, Curiosity used its dust-removing brush and Mars Hand Lens Imager (MAHLI) on Wernecke. About two weeks later, Curiosity used its drill at a point about 1 foot (30 centimeters) to the right of Wernecke to collect the first drilled sample from the interior of a rock on Mars.
“Pilot,” a new sci-fi thriller, follows law enforcement officer Legitt Redd, as he finds himself in the middle of an extraordinary set of circumstances. It is set in a solar system where humans occupy 6 life-supporting planets. Each planet has a different role to the civilisation, one being an energy source, another a prison, another a holiday destination, for example. Legitt is a low ranking officer whom serves for the oppressive government, ‘The Ministry.’ He is introduced as a fairly ordinary, uninspired man whose main duty is to transport prisoners to and from the Prison planet Gorby for processing. He has a long standing friendship and affiliation with one such prisoner – Afyd Geller whom has a reputation as a leader in the underworld and has the respect of many amongst law enforcement. Once a free man, Afyd often invites Leggit for drinking sessions. It‘s on one of these ordinary drinking sessions that the out-of-the-ordinary sequence of events begins. After a few adventure and violent encounters, they travel to the Litton where the apparent real figure head of the underworld resides. Leggit find out that the mythical ‘boogie man’ of child stories of old, Murlon Furlong is in fact a real person, and the all-powerful ruler of criminals.
Murlon sets Leggit, Afyd and other members of this motley crew, on a task to kidnap a spiritual leader. There is a back story of the civilisation’s theology which, in short includes the beginning of time and the eventual coming of salvation.
When this goes horribly wrong Legitt realises his true potential, and attempts to conquer Murlon and avoid swift and violent punishment of The Ministry. This means a whole lot more than he realises and intends the reader to question what is good and what is evil.
This book has great potential. Author R.D. Drabble paints pictures with his words, as if he can see them all around him. Initially this was inspiring to read. You can really imagine the frames in which Drabble was describing. But this positive is also a negative and too much visual description means at times it reads like a script, rather than a novel. There is only the present tense and only one story line, which leaves the reader feeling a bit flat with this one dimensional presentation of an otherwise interesting plot. It would have been a lot more enjoyable if there was a sub-plot or scenes that did not include the main character. Even though Leggit was in every scene, I still felt I didn’t have much insight into him as a character.
Having said that, there are definitely great moments. The technological creations and concepts found in Pilot are really inspiring. They seem to mix the spiritual human elements with technological fantasy. And the Drabble paints an Orwell-esque picture of the Ministry ruled worlds, and there were some phrases that were so poignant and poetic, that is will make you read them twice. The book starts of in a very certain black and white view of the world but progresses a grey outlook, at the same time that character Legitt questions his own morality in certain situations.
But these great moments are sandwiched between cliché, yet lovable characters and the many un-foreshadowed random unnecessary scenarios. There is an appendix of illustrations to support the story lines and backstories, but these don’t really add value or are explored.
Having said that it is clear that Drabble has an amazing amount of imagination. The 6 worlds and their stories are quiet intricate and to be honest, could be explored further in future books. I hope Drabble can express this obvious talent of imagination in future stories, especially if they are in comic or graphic novel format.
Overall, it’s a great read with some cool concepts.
R.D. Drabble is an electrician and science fiction fanatic who has had a lifelong obsession with the strange and inexplicable. It was his love for the unusual that inspired him to write his debut novel Pilot.

A software fix solved a sticky antenna problem on an unmanned cargo ship, a problem that threatened to interfere with the approach and docking to the International Space Station Friday.
Progress 51 successfully docked with the massive orbiting complex at 8:35 a.m. EDT (12:35 p.m. GMT) Friday without the need of assistance from the station crew, which was standing by to take over the docking just in case.
“Progress is safely docked! Big moment for the crew. Hooray!” wrote astronaut Chris Hadfield, the commander of Expedition 35, on Twitter moments after the spacecraft and station docked.
Watch all the action in the video, below:
Crew members are expected to start unloading the three tons of food, fuel, supplies and experiment on board later today (Friday), if all goes according to schedule.
The Russian supply ship has five antennas on board that are used for approaching the station for a docking using the KURS automated system. One of them refused to unfurl as usual after the spacecraft launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday (April 24).
As a backup, crew members could bring the spacecraft in using a manual system that also allows them to view the station from a camera inside Progress.

This particular antenna, NASA said, is normally used to help keep the vehicle properly oriented as it gets closer to the station.
When the Progress spacecraft and station are 65 feet (20 meters) apart, the antenna also provides data on the relative roll of the vehicle with respect to the station.
NASA initially told the crew it was expected to bring the spacecraft in manually. Shortly after 6 a.m. EDT (10 a.m. GMT), however, capsule communicator David Saint-Jacques radioed that NASA was confident a software patch created by Russian ground controllers would address the problem.
Progress 51’s final approach proceeded normally, but controllers took it a little slower than usual to ensure the automated system was working properly with the fix. The approach started slightly early, allowing capture to occur at 8:25 a.m. EDT (12:25 p.m. GMT) — two minutes earlier than planned.
Ground control and the Expedition 35 crew then spent several minutes verifying that the antenna would not interfere with the docking port. With crew members saying they couldn’t hear any funny noises from inside the station, NASA went forward with the hard docking.

The lunar eclipse on April 25 was described by astrophotographer Gadi Eidelheit as “the greatest, slightest eclipse I ever saw!” The brief and small eclipse saw just 1.47% of the lunar limb nicked by the dark umbra or shadow from the Earth. It was visible from eastern Europe and Africa across the Middle East eastward to southeast Asia and western Australia. Here are a few more shots, including a serendipitous shot of an airplane flying through the eclipse!

A close "peak of eternal light" (PEL) near Mercury's south pole
Mercury, traveling in its 88-day-long orbit around the Sun with basically zero axial tilt, has many craters at its poles whose insides literally never see the light of day. These permanently-shadowed locations have been found by the MESSENGER mission to harbor considerable deposits of ice (a seemingly ironic discovery on a planet two-and-a-half times closer to the Sun than we are!*)
But if there are places on Mercury where the Sun never shines (insert butt joke here) then there may also be places where it always does. That’s what researchers are looking for in illumination maps made from MESSENGER data… and they’re getting closer.
The image above shows a region near Mercury’s south pole. The yellow arrow points to the closest thing to a true “peak of eternal light” found thus far on Mercury, a point that receives sunlight about 82% of the time — almost constantly illuminated.
Studies of the illumination conditions near the north and south poles of Mercury are of interest because they can be used to determine locations of permanent shadow, extremely cold places where ice deposits lurk. However, the illumination maps also reveal the locations that receive the maximum duration of sunlight during a Mercury solar day.
A “peak of eternal light” that is illuminated continuously for an entire solar day would be a favorable target for a lander, because solar power would be available all the time. So far, no such peak of eternal light has been identified at Mercury’s south pole.
The spot that get the most illumination (about 82%), is located at 89° S, 50.7° E.
This image was acquired as part of MDIS’s campaign to monitor the south polar region of Mercury. By imaging the polar region approximately every four MESSENGER orbits as illumination conditions change, features that were in shadow on earlier orbits can be discerned and any permanently shadowed areas can be identified after repeated imaging over one solar day.

*Without an atmosphere to hold and distribute heat, any place on Mercury that stays in shadow for any length of time will remain very cold — plenty cold enough for water ice to remain rock-hard indefinitely.

ive images of Saturn's rings, taken by NASA's Cassini spacecraft between 2009 and 2012, show clouds of material ejected from impacts of small objects into the rings. Image Credit: NASA/JPL-Caltech/Space Science Institute/Cornell.
From tell-tale evidence, we know that Earth, our Moon and other bodies in our Solar System are constantly barraged with both small meteoroids and larger asteroids or comets. And sometimes – like in the case of seeing meteors fling across our sky, or flashes on the Moon or Jupiter getting hit by Comet Shoemaker-Levy 9 — we even get to watch as it happens. Now, for the first time the Cassini spacecraft has provided direct evidence of small meteoroids crashing into Saturn’s rings.
Researchers say that studying the impact rate of meteoroids from outside the Saturnian system helps scientists understand how different planet systems in our solar system formed.
Saturn’s rings act as very effective detectors of many kinds of surrounding phenomena, including the interior structure of the planet and the orbits of its moons. For example, a subtle but extensive corrugation that ripples 12,000 miles (19,000 kilometers) across the innermost rings tells of a very large meteoroid impact in 1983.
“These new results imply the current-day impact rates for small particles at Saturn are about the same as those at Earth — two very different neighborhoods in our solar system — and this is exciting to see,” said Linda Spilker, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “It took Saturn’s rings acting like a giant meteoroid detector — 100 times the surface area of the Earth — and Cassini’s long-term tour of the Saturn system to address this question.”
The Saturnian equinox in summer 2009 was an especially good time to see the debris left by meteoroid impacts. The very shallow sun angle on the rings caused the clouds of debris to look bright against the darkened rings in pictures from Cassini’s imaging science subsystem.
This animation depicts the shearing of an initially circular cloud of debris as a result of the particles in the cloud having differing orbital speeds around Saturn. Image credit: NASA/Cornell
“We knew these little impacts were constantly occurring, but we didn’t know how big or how frequent they might be, and we didn’t necessarily expect them to take the form of spectacular shearing clouds,” said Matt Tiscareno, lead author of the paper and a Cassini participating scientist at Cornell University in Ithaca, N.Y. “The sunlight shining edge-on to the rings at the Saturnian equinox acted like an anti-cloaking device, so these usually invisible features became plain to see.”
Tiscareno and his colleagues now think meteoroids of this size probably break up on a first encounter with the rings, creating smaller, slower pieces that then enter into orbit around Saturn. The impact into the rings of these secondary meteoroid bits kicks up the clouds. The tiny particles forming these clouds have a range of orbital speeds around Saturn. The clouds they form soon are pulled into diagonal, extended bright streaks.
“Saturn’s rings are unusually bright and clean, leading some to suggest that the rings are actually much younger than Saturn,” said Jeff Cuzzi, a co-author of the paper and a Cassini interdisciplinary scientist specializing in planetary rings and dust at NASA’s Ames Research Center in Moffett Field, Calif. “To assess this dramatic claim, we must know more about the rate at which outside material is bombarding the rings. This latest analysis helps fill in that story with detection of impactors of a size that we weren’t previously able to detect directly.”
This artist’s impression shows the exotic double object that consists of a tiny, but very heavy neutron star that spins 25 times each second, orbited every two and a half hours by a white dwarf star. The neutron star is a pulsar named PSR J0348+0432 that is giving off radio waves that can be picked up on Earth by radio telescopes. Although this unusual pair is very interesting in its own right, it is also a unique laboratory for testing the limits of physical theories. This system is radiating gravitational radiation, ripples in spacetime. Although these waves (shown as the grid in this picture) cannot be yet detected directly by astronomers on Earth they can be sensed indirectly by measuring the change in the orbit of the system as it loses energy. As the pulsar is so small the relative sizes of the two objects are not drawn to scale.
A unique and exotic laboratory about 6,800 light-years from Earth is helping Earth-based astronomers test Albert Einstein’s theory of general relativity in ways not possible until now. And the observations exactly match predictions from general relativity, say scientists in a paper to be published in the April 26 issue of the journal Science.
Using ESO’s Very Large Telescope along with other radio telescopes, John Antoniadis, a PhD student at the Max Planck Institute for radio Astronomy (MPIfR) in Bonn and lead author of the paper, says the bizarre pair of stars makes for an excellent test case for physics.
“I was observing the system with ESO’s Very Large Telescope, looking for changes in the light emitted from the white dwarf caused by its motion around the pulsar,” says Antoniadis. “A quick on-the-spot analysis made me realize that the pulsar was quite a heavyweight. It is twice the mass of the Sun, making it the most massive neutron star that we know of and also an excellent laboratory for fundamental physics.”
The strange pair consists of a tiny and unusually heavy neutron star that spins 25 times per second. The pulsar, named PSR J0348+0432 is the remains of a supernova explosion. Twice as heavy as our Sun, the pulsar would fit within the confines of the Denver metropolitan area; it’s just 20 kilometers across or about 12 miles. The gravity on this strange star is more than 300 billion times stronger than on Earth. At its center, where the intense gravity squeezes matter even more tightly together, a sugar-cubed-sized block of star stuff would weight more than one billion tons. Only three other pulsars outside globular clusters spin faster and have shorter periods.
J0348+0432 could easily fit within the confines of most American cities, including Denver, Colo. Want to see how big J0348+0432 is compared to your city? Check out this map tool. Zoom into or search for your city, enter 10 km into the radius distance field, and click on a point on the map. Credit: Google MapsIn addition, a much larger white dwarf, the extremely hot, burned-out core of a Sun-like star, whips around J0348+0432 every 2.5 hours.
As a consequence, radio astronomers Ryan Lynch and colleagues who discovered the pulsar in 2011, realized the pair would enable scientists to test theories of gravity that were not possible before. Einstein’s general theory of relativity describes gravity as a curvature in spacetime. Like a bowling ball nestled in a stretched bedsheet, spacetime bends and warps in the presence of mass and energy. The theory, published in 1916, has withstood all tests so far as the simplest explanation for observed astronomical phenomena. Other theories of gravity make different predictions but these differences would reveal themselves only in extremely strong gravitational fields not found within our solar system. J0348+0432 offered the opportunity to study Einstein’s theory in detail.

Antoniadis’ team combined observations of the white dwarf from the European Southern Observatory’s Very Large Telescope with the precise timing of the pulsar from other radio telescopes, including the Green Bank Telescope in West Virginia, Effelsberg 100 meter radio telescope in Germany, and the Arecibo Observatory in Puerto Rico. Astronomers predict such close pulsar binaries radiate gravity waves and lose minute amounts of energy over time causing the orbital period of the white dwarf companion to change slightly. The astronomers found that predictions for this change closely matched those of general relativity while competing theories were different.
“Our radio observations were so precise that we have already been able to measure a change in the orbital period of 8 millionths of a second per year, exactly what Einstein’s theory predicts,” states Paulo Freire, another team member, in the press release.

Over the past 24 hours, the Sun has erupted with two coronal mass ejections (CMEs), sending billions of tons of solar particles into space. While these CMEs are not directed at Earth, they are heading towards Mercury and may affect the Messenger spacecraft, as well as the Sun-watching STEREO-A satellites. One CME may send a glancing blow of particles to Mars, possibly affecting spacecraft at the Red Planet.
This solar radiation can affect electronic systems on spacecraft, and the various missions have been put on alert. When warranted, NASA operators can put spacecraft into safe mode to protect the instruments from the solar material.
The first CME began at 01:30 UTC on April 25 (9:30 p.m. EDT on April 24), and the second erupted at 09:24 UTC (5:24 a.m. EDT) on April 25. Both left the sun traveling at about 800 kilometers (500 miles per second).
