A year of Curiosity

One year ago, after “seven minutes of terror“, Nasa’s Mars Science Laboratory, the 900kg rover Curiosity, landed safely on the Red Planet and was soon taking a look around.   [Image Credit: NASA/JPL-Caltech/Malin Space Science Systems]  Full image and caption here. This scene combines seven images from the telephoto-lens camera on the right side of the Mast Camera (Mastcam) instrument on NASA’s Mars rover Curiosity. The component images were taken between 11:39 and 11:43 a.m., local solar time, on 343rd Martian day, or …

“There’s no place like home…”

I didn’t ‘Wave at Saturn’ on 19 July when the Cassini probe, orbiting the gas giant, was taking a high-definition image of the view back home.  I don’t think it encouraged a proper sense of perspective…  But the resultant image is stunning. [Image Credit: NASA/JPL-Caltech/Space Science Institute] It’s not the first time Cassini has looked home.  Nor is it the only stunning image the probe has provided.  But, as those involved pointed out “We can’t see individual continents or people in this …

“A major difference between the hurricanes is that the one on Saturn is much bigger…”

As I mentioned previously, Saturn doesn’t get the love some of our other gas giants do.  [All hail our friend and lord, Jupiter!  Keeping Ogdy at bay… – Ed]  Indeed… [new link]  But, with the help of Cassini, Saturn does provide some wondrous images.   In some of its first sunlit images of Saturn’s north pole, Cassini has looked inside the mysterious hexagon-shaped jet-stream noted here, and spied an enormous hurricane. In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles …

“comets are like cats: they have tails, and do whatever they want to do”

In the BBC’s science news preview of 2013, reporter Jason Palmer highlights a couple of astronomical events worth keeping an eye out for. In mid-February we will get another reminder we live in a (potentially) violent cosmos – asteroid 2012 DA14 will make a harmless but attention-grabbing pass near the Earth, at a distance just a tenth that of the Moon. Exactly what happens then will determine how near the asteroid’s next pass will be, in 2026. (Don’t worry, signs are pretty …

“Thrust is engaged, and we are now climbing away from Vesta atop a blue-green pillar of xenon ions”

Having arrived at the 530km-wide giant asteroid Vesta in July 2011, in May this year Nasa’s Dawn Mission scientists published some of their findings.  Now Dawn’s ready to head out on the next leg of its journey – Destination [the even larger protoplanet (dwarf planet)] Ceres, ETA 2015. From the JPL press release “Thrust is engaged, and we are now climbing away from Vesta atop a blue-green pillar of xenon ions,” said Marc Rayman, Dawn’s chief engineer and mission director, at NASA’s Jet Propulsion Laboratory, …

“This is an area on Mount Sharp where Curiosity will go”

More wondrous images from Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, now safely on the Martian surface in Gale Crater.  And it’s only warming up its instruments.  Here’s a panaroma of the landing site and the prime mission target, Mount Sharp. Focusing in on Mount Sharp… [Image credit: NASA/JPL-Caltech/MSSS] But the images that have attracted attention are from the telephoto lens [Image credit: NASA/JPL-Caltech/MSSS] As the Nasa press release notes The telephoto images beamed back to Earth show a …

Curiosity drops in on Mars – in Hi-res

Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, may have started roving on the surface of Mars, but there’s still room for more stunning video of its descent. In high-resolution.  Audio from mission control can also be heard, counting down the critical events.  Video from JPL News This movie from NASA’s Curiosity rover shows most of the high-resolution frames acquired by the Mars Descent Imager between the jettison of the heat shield and touchdown.

“Curiosity will soon have a different patch of ground beneath it.”

Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, may have damaged one of two sets of wind sensors in its Rover Environmental Monitoring Station (REMS) during its dramatic landing on Mars, but it will still be providing daily weather reports from the Red Planet. And, as a JPL/Nasa press release noted yesterday – with moving images Curiosity will soon have a different patch of ground beneath it. Today, the six-wheeled rover wiggled its four corner wheels side to side for the …

Curiosity: “This is a very low-resolution panorama”

Having survived the seven minutes of terror, and landed successfully at Gale Crater, earlier this week Nasa’s mobile Mars Science Laboratory (MSL), the 900kg rover Curiosity, lifted its 2m high camera mast.  And took a look at itself.  [Image credit: NASA/JPL-Caltech] Then it took a look at its new surroundings.  In colour. [Image credit: NASA/JPL-Caltech/MSSS] JPL have helpfully put together a video of the panoramic view. As the BBC spaceman, Jonathan Amos, notes The low-resolution vista shows at centre the big mountain …

“Vesta is special”

Having arrived at the 530km-wide giant asteroid Vesta in July last year, Nasa’s Dawn Mission scientists have published some of their findings in Science magazine.  As the BBC’s spaceman, Jonathan Amos, notes They confirm that Vesta has a layered interior with a metal-rich core, just as Earth, Mars, Venus and Mercury do. Using information about the shape of the asteroid and its gravity field, scientists can even say something about the likely size of this core. The Dawn team calculates …

The Serpent Dust Devil of Mars

  [We’re not in Kansas anymore! – Ed]  Indeed.  Here’s a great little video from JPLNews on the 800m-tall dust devil they spotted on Mars in this wondrous image acquired, on Feb 16 2012, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.

“Opportunity on Mars – 8 years and counting!”

Nasa’s Mars Exploration Rover Opportunity landed in Eagle Crater on Mars on Jan. 25, 2004, Universal Time, three weeks after its rover twin, Spirit, had landed halfway around the planet.  Opportunity completed its three-month prime mission in April that year, everything else has been bonus, extended missions.  Spirit is no longer with us.  But Opportunity carries on. [Image credit: NASA/JPL-Caltech/Cornell/Arizona State Univ.] This mosaic of images taken in mid-January 2012 shows the windswept vista northward (left) to northeastward (right) from the location …

Curiosity heads to Mars

Nasa’s Mars Science Laboratory (MSL) successfully launched from the Kennedy Space Centre earlier today on an Atlas 5 rocket at the start of its eight and a half month journey to Mars.  With its massive 900kg rover, Curiosity, it’s being billed as “the biggest and best Mars mission yet.” Mike Meyer is the lead scientist on Nasa’s Mars exploration effort: “MSL plays a central role in a series of missions of looking at Mars and determining whether or not it has the potential for life. …

Chaos on Europa

And that could be a good thing. [Image credit: Nasa/JPL. Image reprocessed by Ted Stryk].  As a BBC report notes, Nasa scientists have published their latest thinking on the chaos terrains of Jovian satellite Europa. [All hail our friend and lord, Jupiter! – Ed] *ahem*.  It suggests that the “chaos terrains form above liquid water lenses perched within the ice shell as shallow as 3 kilometres”.  Here’s a cross-section view through the surface of Europa showing the suspected “Great Lake.”  [Image credit: Britney Schmidt/Dead Pixel …

“An aircraft carrier-sized asteroid will make a safe, close flyby of Earth…”

If the calculations are correct, the 400m-wide asteroid 2005 YU55 will make a safe, close flyby of Earth at around half past eleven tonight (11.28pm GMT).  [If?! – Ed]  If not, we’ll have a wondrous new scar to boast about!  Radar image of asteroid 2005 YU55 obtained on Nov. 7, 2011, at 11:45 a.m. PST (2:45 p.m. EST/1945 UTC), when the asteroid was at 3.6 lunar distances, which is about 860,000 miles, or 1.38 million kilometers, from Earth.

“this is probably the biggest known asteroid to have come this close.”

As spotted by SpaceWeather.  At about 1700 UT (6pm BST) today Asteroid 2011MD will fly past only 12,300 kilometers (7,600 miles) above the Earth’s surface.  [Image credit NASA/JPL] As the diagram shows, that’s close enough to be affected by Earth’s gravity. This small asteroid, only 5-20 meters in diameter, is in a very Earth-like orbit about the Sun, but an orbital analysis indicates there is no chance it will actually strike Earth on Monday. The incoming trajectory leg passes several thousand kilometers …
