Curiosity rover tags Mars with Morse tire tracks

NASA’s Curiosity rover may not look like an urban menace, but the robot explorer will in fact be steadily tagging the Martian surface as it trundles, leaving a name-check of the Jet Propulsion Laboratory back home. The clandestine graffiti is thanks to part of the rover’s visual odometry system, John Graham-Cumming points out, which tracks the marks left by a series of asymmetrically arranged holes in the wheels. The position of those holes, however, isn’t random: in fact, it’s Morse Code.

In fact, there are three sets of notches, which progressively leave three rows of dots and dashes in the Mars grit. That pattern is “. – – -”; “. – – .”; “. – . .” or, translated into English, “JPL”, the acronym for the Jet Propulsion Laboratory.

Unlike the footprints left on the moon by the Apollo astronauts, and which remain to this day thanks to the absence of atmosphere, Curiosity’s tire marks won’t stick around for long. Mars’ atmosphere may be thinner than that of Earth, but that means thermal build-up is quick, causing sea-breeze style winds as gases rush from areas of different temperature.

However, there’s also the potential for far more vigorous dust storms which could easily erase Curiosity’s trail. Storms reaching in excess of 100mph have been observed on Mars, and indeed it was violent dust storms back in 2007 which left the Spirit and Opportunity Mars Exploration Rovers seriously short of power as layers of Martian detritus covered their solar panels and filled the air.

NASA Curiosity landing video: Relive the peanuts moment

NASA’s Curiosity rover may be getting to grips with its new home, but if you didn’t stay up (or get up) to watch the momentous “Seven Minutes of Terror” landing then here’s the video you need to see. The culmination of a 39-week journey from Earth to Mars, the descent was completely programmed as, thanks to time-delays of around fourteen minutes between NASA control and the Curiosity lander and Skycrane itself, there was no way it could be actively remote controlled. Cue several nail-biting minutes as NASA’s Jet Propulsion Laboratory stayed glued to its telemetrics.

In fact, those telemetrics were of a journey that had already begun and ended: by the time the first signs of Curiosity hitting Mars’ upper atmosphere appeared on their screens, the condition of the landing – safe or otherwise – had already been decided. That certainly explains the anxious faces and – eventual – glee of the team when the numbers begin to come through.

Confused by the “peanuts tradition” references you may have heard about the landing? Apparently the good-luck practice began after the first successful Ranger program to land on the moon, which coincided with a Jet Propulsion Laboratory team member eating peanuts. Now, every mission begins with some peanuts to keep channeling that track record.

Since Curiosity and the Skycrane couldn’t beam back their own footage, NASA’s own renderings of the landing process gives more details on the challenge the JPL team undertook. There are images from the first batch beamed back to Earth from Curiosity here.

Scientists warn massive solar flare could harm power grid and satellites

A group of scientists have put the world on alert that a massive solar flare could happen within the next two years that could harm power grids, communications, and satellites around the world. The scientists say that the risk of a massive flare that could harm systems on the earth increase as the sun reaches the peak of its 10-year activity cycle. The scientists say “governments are taking it very seriously.”

According to scientist Mike Hapgood, who specializes in space weather at the Rutherford Appleton Laboratory, solar storms are more commonly being placed on national risk registers used for disaster planning along with events such as tsunamis and volcanic eruption. Hapgood warns that while solar flares are rare, when they happen consequences on earth could be catastrophic. Magnetically-charged plasma thrown from the surface of the sun can have a significant impact on earth.

The chance of a massive solar storm is about 12% for every decade. According to the scientists, the last major solar storm was over 150 years ago, and the odds say that a massive solar storm occurs approximately once in every 100 years. The fear is that these massive solar storms could melt transformers within national power grids, destroy or damage satellites, knockout radio communications, and more.

The largest solar storm ever recorded happened in 1859. British astronomer Richard Carrington observed a large solar eruption, and the geomagnetic storms caused by the eruption took 17 hours to reach the earth. According to reports from 1859, the solar storm is so massive that the aurora borealis was seen as far south as the Caribbean. Had such an event happened in modern times with satellites in orbit, the consequences could have been disastrous.

Astronomers pick up “death cry” of a star being destroyed by a black hole

Black holes are one of the most interesting and destructive forces in all of the universe. The gravity of a black hole is so strong that not even light can escape. However, by methods unknown to scientists today, the black hole blasts matter outwards perpendicular to its accretion disk at almost 90% of the speed of light along the black hole’s spin axis.

A team of astronomers has announced that they have detected what they are calling the “death cry” of a star as it was devoured by a supermassive black hole. The black hole is called Swift J1644+57 and is 3.9 billion light-years away from Earth. The black hole is located in the constellation Draco and was discovered on March 28, 2011.

The black hole was discovered by NASA’s Swift satellite as the satellite conducted its gamma ray search. The satellite discovered a gamma ray burst from the black hole that faded out gradually, nothing similar had been detected before. Close observation of the black hole revealed the faint, periodic signal that astronomer Jon Miller of the University of Michigan says corresponds in frequency to an ultralow D-sharp.

Scientists believe that the signals emanate from material that is about to be sucked into the black hole. According to the scientists, the star that was sucked in by the black hole would have been subjected to powerful tidal forces as it neared the black hole and was torn apart. Some of the gas would’ve been sucked into the black hole and formed an accretion disk of material around it. The innermost part of that disc would’ve been heated to a temperature of millions of degrees causing it to emit x-rays. The black hole was discovered as it consumed the star because one of the jets of matter emitted by the black hole was pointed straight at Earth. According to the scientists, the star being sucked in the black hole committed a “cry” every 3.5 minutes.

NASA Curiosity sends back more detailed view of Mars

Curiosity’s main cameras may not be due to come online until they’ve unfurled later this week, but the Mars rover is already beaming back better shots now that it has whipped off the dust protection. The first batch of photos from the freshly-landed rover were fuzzy – thanks to a combination of dust whirls from the Skycrane lander and the protective covers on the cameras themselves – but as things settle and Curiosity whirs into life, the images are getting a lot clearer.

So far there’s only one new image from the rover, limited by the need to route any transmissions via the Odyssey satellite in orbit around the red planet. Odyssey took up position around Mars in 2001, and was expected to be the weak spot in the Curiosity landing: with systems already failing in places, it could have left the NASA groundcrew at the Jet Propulsion Laboratory temporarily blind as to whether the rover had made it to the surface.

Thankfully those pieces slotted into place, giving Curiosity time to blast one last, higher-resolution shot back home. In the picture, taken by a rear “Hazcam” – a monochrome, fish-eye camera mounted on one corner of the rover, and intended to be used for guidance – you can see the curve of the horizon and one of Curiosity’s wheels. The white, ridged object in the lower right corner is believed to be part of the assembly for the dust cover itself.

Full color images are due to be collected later in the week, when the 1600 x 1200 primary cameras come online. They’re mounted on the head of the rover, which is currently tucked away as part of the landing procedure, and can shoot both stills and 10fps 720p HD video footage.

Mars Curiosity Is Your Excuse for Anything Today [Mars Landing]

You overslept, burnt your breakfast, spilt coffee down your shirt, and stumbled into work looking a wreck—a bit like every other Monday morning, just ten times worse. But that’s OK, because you have an excuse: last night, you were watching history being made. More »

NASA’s Curiosity is biggest Mars mission yet (in more ways than one)

Safely landed on Mars, NASA‘s Curiosity rover dwarfs its robot predecessors by a factor of 2:1, though we’ll need to wait for it to take off its lenscap before we get a proper look at the Martian surface. Measuring 3m long, the six-wheeled Curiosity is double the size of the previous Exploration rovers and uses its heft to carry fifteen times heftier instruments with which it will check for evidence of life on the red planet.

In fact, Curiosity is five times heavier than previous landers, and – as the group photo above shows – is more akin to a small car than the human-scaled rovers that came before it. Altogether, that has allowed for equipment of the sort never before taken to Mars: Curiosity carries a laser that can check out the elemental composition of distant rocks, for instance, while close-up testing is done by loading an internally-carried lab with samples gathered up by a robotic arm.

First step, however, will be orienting Curiosity and gathering some photos for the album. The first batch of shots already sent back to Earth are comparatively low-resolution, since they were taken with the so-called “Hazcam”; in contrast, the two main cameras will grab full color 1600 x 1200 stills (or 720p video at 10fps), but will only be operation when the “head” of the rover is unpacked and extended.

At that point, the Hazcams – of which there are four, at the extremes of the rover – will be used for autonomous navigation, building a 3D perspective of the environment around Curiosity and its robotic arm. There are seventeen cameras in total, spanning visible light through more specific purposes depending on the scientific intention.

NASA expects the Curiosity mission to last two years, though it’s possible the rover could outlast its original estimates. The last Exploration rover, “Opportunity”, recently woke from its fifth winter to continue trundling around Mars.

There’s more on the “7 minutes of terror” process of landing Curiosity on Mars in our full SlashGear 101 on the subject. With transmission delays back to Earth amounting to around fourteen minutes, and the landing itself taking roughly half that time, the entire process had to be automated as there was no way for it to be manually remote-controlled.

NASA’s Curiosity Mars landing successful, first pictures trickling in (video)

NASA's Curiosity Mars landing successful, first pictures trickling in

After “seven minutes of terror” involving guided entry, parachute and powered descent, and even a sky crane, NASA’s Curiosity rover has successfully touched down on the surface of Mars. Better yet, the 2,000lbs (900kg) science lab has established communications with Earth and is sending back telemetry along with the first pictures of Gale crater. These initial grayscale images are only 256 x 256 pixels in size but show Curiosity’s shadow on the Martian soil. Peek at our galley below and stay tuned for updates.

Update: Hit the break to check out a video of all the “seven minutes of terror” highlights.

First Mars photos projected back from Curiosity Rover

Less than an hour ago, NASA accomplished a new feat of engineering supremacy with the landing of the Curiosity Rover to the surface of Mars – and the first photos from that craft have been sent back to Earth already. As it was revealed about and around the landing sequence for this craft, the delay between the tech on the planet now and us here at home on Earth is about 14 minutes. What we’re seeing now are photos taken from the Curiosity River and projected back to our planet in less than a half hour – fresh as we’ve ever seen them!

What you’re seeing are some rather dusty images straight from the Curiosity Rover as it’s touched down on the planet Mars. These are the first bits of data we’ll be receiving from the planet that’ll be able to be made sense of by the masses. For all information regarding new forms of life, little green men, and signs of water, we’ll have to wait a bit longer.

You’re seeing shadows of the rover as it sits on the surface of Mars as well as images of its wheels. There are only a few small images at the moment, but more are certainly on the way from NASA very soon. The reason the view right now is so very dusty is that the area surrounding the craft is essentially one massive cloud of debris blown up by the landing sequence. Subsequent shots of the surface of the planet will be clearer – we hope!
