NASA's Lunar Reconnaissance Orbiter Camera captured a boulder on the Moon that decided to go on a little journey. Looking at the track, you'd think that this happened recently. Well, in geologic times perhaps:

The lonely journey of this large boulder is apparent from its track in a sloping regolith surface. A casual glance might suggest that it happened last week, or even that its rolling might resume at any moment. However, closer inspection will detect a few craters that clearly superpose and therefore post-date the track, showing that this 9-meter diameter boulder stopped rolling some time ago. Impacts are used in this way to provide a relative sense for the timing of events on planetary surfaces across the solar system. The procedure assumes a steady flux of impacting bodies in each size range, with smaller impacts being much more frequent than large impacts.

Though long ago to humans, however, this boulder's journey was made in geologically recent times. Studies suggest that regolith development from micrometeorite impacts will erase tracks like these over time intervals of tens of millions of years. If rate estimates are accurate, this boulder track might not be older than 50-100 million years. Eventually its track will be erased completely.

One of NASA's Gravity Recovery and Interior Laboratory (GRAIL) lunar spacecraft has finally captured the far side (or the dark side, if you're poetically inclined) of the Moon on video. So far, no Cybertronian spacecraft was found.

In the video, the north pole of the moon is visible at the top of the screen as the spacecraft flies toward the lunar south pole. One of the first prominent geological features seen on the lower third of the moon is the Mare Orientale, a 560-mile-wide (900 kilometer) impact basin that straddles both the moon's near and far side.

The clip ends with rugged terrain just short of the lunar south pole. To the left of center, near the bottom of the screen, is the 93-mile-wide (149 kilometer) Drygalski crater with a distinctive star-shaped formation in the middle. The formation is a central peak, created many billions of years ago by a comet or asteroid impact.

NASA has released a high-definition image of the Earth it calls Blue Marble 2012.

A ‘Blue Marble’ image of the Earth taken from the VIIRS instrument aboard NASA’s most recently launched Earth-observing satellite – Suomi NPP. This composite image uses a number of swaths of the Earth’s surface taken on January 4, 2012. The NPP satellite was renamed ‘Suomi NPP’ on January 24, 2012 to honor the late Verner E. Suomi of the University of Wisconsin.

The original Blue Marble image was taken in 1972 by astronauts aboard Apollo 17. Until today, it was my desktop image. NASA has made the new image available for download in several sizes. Link to story. Link to image. -via Buzzfeed

Before construction on the International Space Station began, a flood of conceptual designs passed across the drawing board, an Wired has gathered a gallery of designs that didn’t make the cut.

From far out, scifi influenced designs to more mundane designs that missed the mark by a hair, these concept drawings are fun to peruse and take us back to a simpler time in space design, a time when landing a space shuttle on a runway atop the space station actually made a lot of sense.

Cloudy skies over Beijing? Actually, no - the gray haze you see above is pollution.

NASA's Aqua satellite captured the patch of winter haze over the mega cities of Beijing and Tianjin on January 10, 2012:

One major constituent of haze is particle pollution, such as dust, liquid drops, and soot from burning fuel or coal. Particles smaller than 10 micrometers (called PM 10) are small enough to enter the lungs, where they can cause respiratory problems. The density of PM10 reached 560 micrograms per cubic meter of air on January 10, said the Beijing Environment Protection Bureau. By contrast, U.S. cities exceed air quality standards when PM10 concentrations reach 150 micrograms per cubic meter.

But most of the pollution that makes up haze isn’t PM10; it’s finer particles, smaller than 2.5 micrometers in diameter (PM2.5). These particles can embed themselves deep in the lungs and occasionally enter the blood stream. The fine particles are highly reflective, sending sunlight back into space. The Chinese government does not currently measure PM2.5, but the U.S. Embassy in Beijing reports their measurements hourly in a Twitter feed. On the morning of January 10, PM2.5 measurements were off the scale, though by afternoon they had dropped to moderate levels. The Beijing Environmental Bureau will start releasing PM2.5 measurements sometime before January 23, the Chinese New Year.

The action begins shortly before sunset. Around 4:30 pm to 5:00 pm local time, just as the sky is assuming its evening hue, Venus will pop into view, glistening bright in the deepening twilight. No more than 6 degrees to the right lies the crescent Moon, exquisitely slender, grinning like the Cheshire cat with his head cocked at humorous attention. This is a wonderful time to look; there are very few sights in the heavens as splendid as Venus and the Moon gathered close and surrounded by twilight blue.

But don’t go inside yet, because the view is about to improve. As the sky fades to black, a ghostly image of the full Moon materializes within the horns of the lunar crescent. This is caused by Earthshine, a delicate veil of sunlight reflected from our own blue planet onto the dusty-dark lunar terrain. Also known as “the Da Vinci glow,” after Leonardo da Vinci who first understood it 500 years ago, Earthshine pushes the beauty of the conjunction over the top.

Meanwhile, Jupiter will be looking down on it all from a perch overhead in the constellation Pisces. In ascending order, Jupiter, Venus and the Moon are the three brightest objects in the night sky, able to pierce city lights and even thin clouds. Almost everyone, everywhere will be able to see them.

Apollo 8 wasn’t just a NASA mission; it was the biggest, coolest, most mind-blowing Christmas special of all time.

The men of Apollo 8 -Frank Borman, James Lovell, and William Anders- had their work cut out for them. They were slated to become the first humans ever to leave the Earth’s orbit, enter lunar orbit, and see the far side of the Moon. But as their launch date approached in December 1968, NASA added an even more terrifying task to the crew’s to-do list: public speaking. The agency wanted the astronauts to host a live broadcast from the spacecraft on Christmas Eve. Worse still, the men were given only one cryptic instruction: “Say something appropriate.”

The astronauts were in a tough spot. When millions of people of different faiths and backgrounds are listening, what exactly constitutes appropriate? To make matters trickier, 1968 had been a grim year for Americans -the Vietnam War was raging, and Robert Kennedy and Martin Luther King, Jr. had both been assassinated. How could the astronauts simultaneously orbit the Moon, introduce millions to outer space on TV, and buoy the American spirit?

The men were stumped. They began enlisting the help of media experts, who were mostly just as clueless as they were. The answer finally came from the wife of Joe Laitin, a former reporter who’d worked as a public affairs officer under five presidents. She made an elegant, simple suggestion: Why not just read from the book of Genesis?

The astronauts jumped at the idea. They reasoned that genesis had a broad enough appeal across religions to add a hint of spirituality without ostracizing non-Christians. Borman, the mission’s commander, had the first ten verses typed onto fireproof paper and tucked the sheet into his flight plan. The astronauts had their script.

The broadcast began with the crew showing some of the first images of Earth ever seen from space. Lovell remarked, “The vast loneliness up here of the Moon is awe-inspiring, and it makes you realize just what you have back there in Earth.”

Viewers were captivated. But as airtime dwindled, Anders revealed that the crew had a special message for all the people of the planet. He started with the familiar “In the beginning, God created the heaven and the Earth…”

He read the first four verses; Lovell read four more. Borman recited the last two and ended the show, saying, “And from the crew of Apollo 8, we close with a good night, good luck, a Merry Christmas, and God bless all of you -all of you on the good Earth.”

In the end, the crew’s effort paid off. Half a billion people tuned in, making it the largest TV event in history at the time, and the reception was overwhelmingly positive; even Walter Cronkite admitted that he had tears in his eyes. Of course, not everyone on Earth was thrilled; one atheist activist sued NASA for interjecting religion into a government project, but the Supreme Court dismissed the lawsuit. Enough nitpicking! The Christmas Eve special won an Emmy, and Time made the crew the magazine’s “Men of the Year” for 1968. The broadcast was truly out of this world.

Astronauts aboard the International Space Station will soon get a respite from having to wear stinky clothes: NASA is commissioning a washer-dryer combo:

Imagine putting dirty clothes into a washing machine, leaving, and only coming back once the freshly cleaned clothes have been dried out by microwaves. That out-of-this-world-laundry concept could someday become a reality for astronauts and space explorers headed for the moon, asteroids or Mars.

Such a washing machine is designed to clean dirty astronaut clothing inside a sealed plastic bag that can also receive a drying blast of microwaves. The simple one-step process represents an energy- and water-efficient solution that spares space travelers from hauling a water-intensive washing machine up into space or bringing along disposable clothing.

Which brings the obvious question to mind: what have they been doing with their clothes?

The Daily Mail has the answer:

Brave - and strong-stomached - astronauts usually wear underwear for three or four days before putting them in a capsule that is ejected and burns up in the atmosphere. Other clothes are worn 'for months'.

So if you saw a streak of light in the sky, and you thought you've been wishing upon a falling star, think again. That may just be some astronaut's underwear. Thanks Tiffany!

“We’ve come a long way across the solar system,” says Glen Fountain, New Horizons project manager at the Johns Hopkins University Applied Physics Laboratory. “When we launched [on Jan. 19, 2006] it seemed like our 10-year journey would take forever, but those years have been passing us quickly. We’re almost six years in flight, and it’s just about three years until our encounter begins.”

From New Horizons’ current distance to Pluto – about as far as Earth is from Saturn – Pluto remains just a faint point of light. But by the time New Horizons sails through the Pluto system in mid-2015, the planet and its moons will be so close that the spacecraft’s cameras will spot features as small as a football field.

The most detailed moon map yet has been constructed from images by NASA’s Lunar Reconnaissance Orbiter (LRO). Technicians from Arizona State University compiled the map which shows elevation changes as small as 100 meters.

The near-global topographic map was constructed from 69,000 WAC stereo models and covers the latitude range 79°S to 79°N, 98.2% of the entire lunar surface. Due to persistent shadows near the poles it is not possible to create a complete stereo based map at the highest latitudes. However, another instrument onboard LRO called LOLA excels at mapping topography at the poles. Since LOLA ranges to the surface with its own lasers, and the LRO orbits converge at the poles, a very high resolution topographic model is possible, and can be used to fill in the WAC “hole at the pole.” The WAC topography was produced by LROC team members at the German Aerospace Center.

Look closely at the photo above and you can pick out 5 of Saturn's 60 natural satellites (Janus, Pandora, Enceladus, Mimas, and Rhea) as well as the planet's iconic rings:

A quintet of Saturn's moons come together in the Cassini spacecraft's field of view for this portrait.

Janus (179 kilometers, or 111 miles across) is on the far left. Pandora (81 kilometers, or 50 miles across) orbits between the A ring and the thin F ring near the middle of the image. Brightly reflective Enceladus (504 kilometers, or 313 miles across) appears above the center of the image. Saturn's second largest moon, Rhea (1,528 kilometers, or 949 miles across), is bisected by the right edge of the image. The smaller moon Mimas (396 kilometers, or 246 miles across) can be seen beyond Rhea also on the right side of the image.

This view looks toward the northern, sunlit side of the rings from just above the ringplane. Rhea is closest to Cassini here. The rings are beyond Rhea and Mimas. Enceladus is beyond the rings.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on July 29, 2011. The view was acquired at a distance of approximately 1.1 million kilometers (684,000 miles) from Rhea and 1.8 million kilometers (1.1 million miles) from Enceladus. Image scale is 7 kilometers (4 miles) per pixel on Rhea and 11 kilometers (7 miles) per pixel on Enceladus.

No, that's not a meteor or an alien spaceship - that's an image of the falling NASA satellite UARS, captured by amateur astronomer Thierry Legault:

The six-tonne, 20-year-old spacecraft has fallen out of orbit and is expected to crash somewhere on Earth on or around 24 September.

The US space agency says the risk to life from the Upper Atmosphere Research Satellite (UARS) is 1 in 3,200. [...] Nasa says that most of the satellite will break or burn up before reaching Earth.

But scientists have identified 26 separate pieces that could survive the fall through the atmosphere. This debris could rain across an area 400-500km (250-310 miles) wide.

This image was selected as the Astronomy Picture of the Day last weekend. It was taken by the Cassini probe in 2006 from the shadow of Saturn.

First, the night side of Saturn is seen to be partly lit by light reflected from its own majestic ring system. Next, the rings themselves appear dark when silhouetted against Saturn, but quite bright when viewed away from Saturn, slightly scattering sunlight, in this exaggerated color image. Saturn’s rings light up so much that new rings were discovered, although they are hard to see in the image. Seen in spectacular detail, however, is Saturn’s E ring, the ring created by the newly discovered ice-fountains of the moon Enceladus and the outermost ring visible above. Far in the distance, at the left, just above the bright main rings, is the almost ignorable pale blue dot of Earth.

Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars’ southern hemisphere.

“The best explanation for these observations so far is the flow of briny water,” said Alfred McEwen of the University of Arizona, Tucson. McEwen is the principal investigator for the orbiter’s High Resolution Imaging Science Experiment (HiRISE) and lead author of a report about the recurring flows published in Thursday’s edition of the journal Science.

Some aspects of the observations still puzzle researchers, but flows of liquid brine fit the features’ characteristics better than alternate hypotheses. Saltiness lowers the freezing temperature of water. Sites with active flows get warm enough, even in the shallow subsurface, to sustain liquid water that is about as salty as Earth’s oceans, while pure water would freeze at the observed temperatures.

“These dark lineations are different from other types of features on Martian slopes,” said Mars Reconnaissance Orbiter Project Scientist Richard Zurek of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “Repeated observations show they extend ever farther downhill with time during the warm season.”

Discussion about weather is often relegated to the realm of awkward small-talk and complaints about the heat/snow/rain, but extraplanetary weather is a different thing altogether… at least for me. These images of a storm over Saturn’s surface–the largest ever recorded on the planet–are interesting and beautiful. The false color doesn’t hurt, but it’s still so massive that imagining it takes a bit of brain yoga.

First detected in December 2010, the storm has developed from a small spot into a raging storm covering an area about 4 billion square kilometres, or eight times the surface of the Earth, in Saturn’s northern hemisphere.

The false colours on the images mark the different altitudes of clouds: blue clouds reside at the highest altitude with those in red at the lowest. The two high-resolution images at the bottom are mosaics, each made up of 84 images taken over 4.5 hours. The lower of the two was taken 11 hours, or one Saturn day, after the first.

The top two images are enlargements taken from the earlier of the two bottom images. They show the head of the storm (top left) and its turbulent middle (top right). Calculations reveal that the head of the storm is moving west at a speed of about 100 kilometres per hour.

With the final launch of NASA’s space shuttle program scheduled for Friday, it’s the perfect time to do a little shuttle retrospective. Over on mental_floss, Miss Cellania talks about the beginnings of the 35-year space shuttle program and what NASA has to do with Star Trek.

As soon as Apollo 11 delivered astronauts to the lunar surface, NASA was asked to develop a new space program that would be more immediately useful and (most importantly) more cost-efficient. The Apollo program continued through mission 17 in 1972, but meanwhile engineers were developing a reusable spacecraft. It was a totally new concept, a vehicle tough enough to go into space, complete mission after mission, and land on earth with such little damage that it could be sent up again. We didn’t see the first space shuttle until 1976. It was called Enterprise.

It sounds kind of delicious the way they describe it but NASA has discovered a mysterious cluster of “frothy magnetic bubbles” at the edge of our solar system. Discovered by probes Voyager 1 and Voyager 2 the bubbles are in the ‘foam zone” or heliosheath. Scientists now have a few theories on what the bubbles are or may do.  Sadly none of them are that the solar styem is one giant milk shake.

The simplest way to describe what both probes are currently travelling through is as a grouping of frothy magnetic bubbles. NASA is also referring to the area as the “foam zone.” The bubbles are not small, with each measuring around 100 million miles wide.

The foam zone was entered in 2007 by Voyager 1 and 2008 by Voyager 2. The reason we are only now hearing the details is because scientists had no idea what it was both probes were travelling through. A couple of years later and NASA believe they have worked it out.

This morning, a massive solar flare was caught live by NASA’s Solar Dynamics Observatory. Though the flare is quite large (a M2.5, or medium-sized flare, in terms of energy), it isn’t expected to alter the weather here on Earth.

“I’ve never seen material released like this before, such a huge amount that falls back down in such a spectacular way,” says Goddard Spaceflight Center’s Dr. C. Alex Young. “It looks like someone just kicked a giant clod of dirt into the air and it fell back down.”
