New pictures of water ice at Mercury’s north pole — the first such optical images ever — could help scientists better understand how water came to planets in the rest of the Solar System, including Earth. The image you see above came courtesy of NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft.
Mercury is a hot planet (it’s the closest one to the Sun), so the only way the ice survives is in deep shadow. This makes it hard to spot unless scientists use some clever techniques. In this case, they examined some scattered light from Prokofiev, the biggest crater in Mercury’s north pole suspected to hold the deposits.
The pictures show that Prokofiev’s surface water ice likely arrived after the craters underneath. And in an intriguing find, there is probably other water ice sitting under dark materials believed to be “frozen organic-rich compounds,” stated the Johns Hopkins University Applied Physics Laboratory.
“This result was a little surprising, because sharp boundaries indicate that the volatile deposits at Mercury’s poles are geologically young, relative to the time scale for lateral mixing by impacts,” stated lead researcher Nancy Chabot, the Instrument Scientist for MESSENGER’s Mercury dual imaging system.

“One of the big questions we’ve been grappling with is ‘When did Mercury’s water ice deposits show up?’ Are they billions of years old, or were they emplaced only recently?”, added Chabot, who is a planetary scientist at the Johns Hopkins University Applied Physics Laboratory in Maryland. “Understanding the age of these deposits has implications for understanding the delivery of water to all the terrestrial planets, including Earth.”
Another intriguing property comes when scientists compare Mercury to the Moon: because the ice looks different on both relatively atmosphere-less bodies, scientists believe the water came more recently to the Moon. But more study is required.

How possible is it to land humans on Mars? And can Mars One, the organization proposing to start with sending four astronauts one way, capable of doing it by 2025 as it promises?
A new study says that the Mars One concept could fail on several points: oxygen levels could skyrocket unsafely. Using the local resources to generate habitability is unproven. The technology is expensive. But the founder of Mars One says the Massachusetts Institute of Technology (MIT) student study is based on the wrong assumptions.
“It’s based on technology available on the ISS [International Space Station],” said Bas Landorp in an interview with Universe Today. “So you end up with a completely different Mars mission than Mars One. So their analysis has nothing to do with our mission.”
The mission has sparked a debate about sending humans on a trip with no promise for a return, but thousands of applicants vied for the chance to do it. After two cuts, the interim shortlist is now at 700 people. Those folks are awaiting interviews (more news is coming shortly, Landorp says) and no date has yet been announced for the next “cut.”

A couple of weeks ago, MIT students presented a technical feasibility analysis of Mars One at the International Astronautical Congress in Toronto, Canada. The study is 35 pages long, so we recommend you read it to get the whole picture. The students’ main concerns are that crops (if they are responsible for 100% of the food) would send oxygen levels to unsafe margins, with no way to remove it. There are concerns with how well the in-situ resource utilization (using the resources on Mars to live off of) would perform. And the mission would cost $4.5 billion at a minimum — for the first crew only.
Cost: To get to Mars, the students say it will cost $4.5 billion and take 15 Falcon Heavy launches (a proposed next-generation rocket from SpaceX). Landorp says he can do it for $1.625 billion (since he doesn’t require constant Earth resupply) and as few as 13 launches (assuming $125 million per launch, a figure Landrop says is from SpaceX) by taking advantage of a few quirks of physics. If Mars One chooses a landing site that is four kilometers (2.5 miles) below the average Martian surface height, they will have both a thicker atmosphere and more time to land the payloads than, say, the Curiosity rover that landed about two kilometers (1.24 miles) above the average surface height. Mars One’s numbers show they could carry a payload of 2,500 kilograms (5,512 pounds) per mission, which they say is well within reach of what spacecraft can do today. The 13 launches would be divided into 11 robotic launches to send equipment to the surface, and two for humans (one to head to Earth orbit for assembly, and the other for the colonists to head to the in-orbit spacecraft and fly to Mars. The assembly crew would then fly back to Earth on the launch vehicle.)
Life support: While many of the technologies planned for use in life support are similar to those on the ISS — such as a trace gas system for air revitalization — Landorp says there will be some crucial differences. They are in talks with Paragon Space Systems Corp. (which describes itself as an environmental control firm for extreme environments, and whose customers include NASA and Bigelow.) As for the unsafe oxygen levels, Landorp points out there are plenty of oxygen removal systems available and that are used in hospitals and militaries. All that is needed is more testing in space. Landorp also points out these systems will be tested for two years robotically before humans land. “If that is not successful, then obviously we will not send humans,” he said.

In-situ resource utilization: Landorp acknowledges this requires more study, but says the robotic missions will be an important precursor for the human landings. Technologies needing to be developed will include nitrogen extraction from the Martian atmosphere. Oxygen production from water is well-studied in space, but water from the Martian surface (through vaporizing water in the soil) will require more work.
Another concern raised in media from time to time is where the money is coming from to fund Mars One. Landorp says right now funds are flowing from private investors. Mars One representatives are also in serious talks with a United Kingdom-based listed investment fund willing to finance the mission. In the long run, Landorp is confident money will come from broadcast deals similar to what partially fund the Olympics and the Fédération Internationale de Football Association (FIFA) competitions. Associated sponsorships would also help. But these won’t kick in until the colonists launch and land, since that’s when the world’s eyeballs will be on the mission.
Another stream of revenue, which may take five to seven years to kick in, will be intellectual property deals Mars One one representatives are working on closing now with potential suppliers, such as Lockheed Martin and Paragon. These agreements, should they go through as planned, would give Mars One a share of future revenue from any technologies flowing from the IP. “In the short term it’s not that interesting, it takes time to mature, but in the long term that will be interesting,” Landorp said.
A collage of moon photos that photographer David Blanchflower took between March and October 2014 from Newcastle upon Tyne, United Kingdom, using a Nikon Coolpix L810 camera. One picture used a telescope (Skywatcher Explorer 200P).
We think of the Moon as a grey and unchanging world, but throw in the effects of Earth’s atmosphere and orbit and you get some really cool effects. It can look yellow or red or almost blue. It changes from a full disc to a crescent and back again. It gets bigger and smaller as the Moon drifts forward and backward in its orbit. Sometimes it’s even eclipsed.
Remarkably, one photographer has captured many of these moods in a single collage. The picture above from David Blanchflower was recently posted to the Universe Today Flickr pool, showing images between March and October 2014.
“All from Newcastle upon Tyne with a Nikon Coolpix L810 Camera,” Blanchflower wrote. “One of the pictures was taken with the aid of a telescope (Sky-Watcher Explorer 200P). They show a variety of colours and phases.”
We’d love to see your shots of the moon as well, so please feel free to contribute to the Flickr pool. Posting a picture means we could use it in a future story.

So this spacecraft — taking this picture — is going to land on the surface of THAT comet. Doesn’t this give you a pit in your stomach? This is a selfie taken from the Philae spacecraft that, riding piggyback, captured the side of the Rosetta spacecraft orbiting Comet 67P/Churyumov-Gerasimenko.
The image is so close-up — just 9.9 miles (16 kilometers) from 67P’s surface — that mission planners can even spot Landing Site J on the comet’s smaller lobe.
“Two images, one with a short exposure time, one with a longer one, were combined to capture the whole dynamic range of the scene, from the bright parts of the solar arrays to the dark comet and the dark insulation cladding the Rosetta spacecraft,” the European Space Agency stated.
It’s quite the zoom-in after the last selfie that Philae produced for the public in September, which was taken from 31 miles (50 kilometers) away. The spacecraft is expected to make the first touchdown ever on a comet next month. Rosetta, meanwhile, will keep following 67P as it gets closest to the sun in 2015, between the orbits of Earth and Mars.
Tomorrow (Oct. 15), mission managers will announce if Site J is go or no go for a landing. More information is coming from Rosetta’s examination of the site from its new, lower altitude of 6.2 miles (10 kilometers).
The feature called Maskelyne is one of many newly discovered young volcanic deposits on the moon. Called irregular mare patches, these areas are thought to be remnants of small lava eruptions that occurred recently in the moon's past. To view this image correctly, the large, dark, circular feature right of center is pancake-like dome that rises ABOVE the surrounding lighter-toned terrain. Lower domes, many pitted with small craters, are seen from left to right across the photo. Credit: NASA/GSFC/Arizona State University
The Moon’s a very dusty museum where the exhibits haven’t changed much over the last 4 billion years. Or so we thought. NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the Moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago.
Some volcanic deposits are estimated to be 100 million years old, meaning the moon was spouting lava when dinosaurs of the Cretaceous era were busy swatting giant dragonflies. There are even hints of 50-million-year-old volcanism, practically yesterday by lunar standards.
Ina Caldera sits atop a low, broad volcanic dome or shield volcano, where lavas once oozed from the moon’s crust. The darker patches in the photo are blobs of older lunar crust. As in the photo of Maskelyne, they form a series of low mounds higher than the younger, jumbled terrain around them. Credit: NASA
The deposits are scattered across the Moon’s dark volcanic plains (lunar “seas”) and are characterized by a mixture of smooth, rounded, shallow mounds next to patches of rough, blocky terrain. Because of this combination of textures, the researchers refer to these unusual areas as “irregular mare patches.”
Measuring less than one-third mile (1/2 km) across, almost all are too small to see from Earth with the exception of Ina Caldera, a 2-mile-long D-shaped patch where blobs of older, crater-pitted lunar crust (darker blobs) rise some 250 feet above the younger, rubbly surface like melted cheese on pizza.
Lavas on the moon were thin and runny like this flow photographed in Kilauea, Hawaii. Credit: USGS
Ina was thought to be a one-of-a-kind until researchers from Arizona State University in Tempe and Westfälische Wilhelms-Universität Münster in Germany spotted 70 more patches in close-up photos taken by the LRO. The large number and the fact that the patches are scattered all over the nearside of the Moon means that volcanic activity was not only recent but widespread.
Astronomers estimate ages for features on the moon by counting crater numbers and sizes (the fewer seen, the younger the surface) and the steepness of the slopes running from the tops of the smoother domes to the rough terrain below (the steeper, the younger).
“Based on a technique that links such crater measurements to the ages of Apollo and Luna samples, three of the irregular mare patches are thought to be less than 100 million years old, and perhaps less than 50 million years old in the case of Ina,” according to the NASA press release.

The young mare patches stand in stark contrast to the ancient volcanic terrain surrounding them that dates from 3.5 to 1 billion years ago.
For lava to flow you need a hot mantle, the deep layer of rock beneath the crust that extends to the Moon’s metal core. And a hot mantle means a core that’s still cranking out a lot of heat.
Scientists thought the Moon had cooled off a billion or more years ago, making recent flows all but impossible. Apparently the moon’s interior remained piping hot far longer than anyone had supposed.
“The existence and age of the irregular mare patches tell us that the lunar mantle had to remain hot enough to provide magma for the small-volume eruptions that created these unusual young features,” said Sarah Braden, a recent Arizona State University graduate and the lead author of the study.
It takes two to tango. The moon’s gravity raises a pair of watery bulges in the Earth’s oceans creating the tides, while Earth’s gravity stretches and compresses the moon to warm its interior. Illustration: Bob King
One way to keep the Moon warm is through tidal interaction with the Earth. A recent study points out that strains caused by Earth’s gravitational tug on the Moon (nearside vs. farside) heats up its interior. Could this be the source of the relatively recent lava flows?
So the pendulum swings. Prior to 1950 it was thought that lunar craters and landforms were all produced by volcanic activity. But the size and global distribution of craters – and the volcanoes required to produce them – would be impossible on a small body like the Moon. In the 1950s and beyond, astronomers came to realize through the study of nuclear bomb tests and high-velocity impact experiments that explosive impacts from asteroids large and small were responsible for the Moon’s craters.
This latest revelation gives us a more nuanced view of how volcanism may continue to play a role in the formation of lunar features.

NASA inaugurated a new era of research for the International Space Station (ISS) as an Earth observation platform following the successful installation and activation of the ISS-RapidScat science instrument on the outposts exterior at Europe’s Columbus module.
The ISS Rapid Scatterometer, or ISS-RapidScat, is NASA’s first research payload aimed at conducting near global Earth science from the station’s exterior and will be augmented with others in coming years.
RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring.
The 1280 pound (580 kilogram) experimental instrument is already collecting its first science data following its recent power-on and activation at the station.
“Its antenna began spinning and it started transmitting and receiving its first winds data on Oct.1,” according to a NASA statement.
The first image from RapidScat was released by NASA on Oct. 6, shown below, and depicts preliminary measurements of global ocean near-surface wind speeds and directions.
Launched Sept. 21, 2014, to the International Space Station, NASA’s newest Earth-observing mission, the International Space Station-RapidScat scatterometer to measure global ocean near-surface wind speeds and directions, has returned its first preliminary images. Credit: NASA-JPL/Caltech
The $26 million remote sensing instrument uses radar pulses to observe the speed and direction of winds over the ocean for the improvement of weather forecasting.
“Most satellite missions require weeks or even months to produce data of the quality that we seem to be getting from the first few days of RapidScat,” said RapidScat Project Scientist Ernesto Rodriguez of NASA’s Jet Propulsion Laboratory, Pasadena, California, which built and manages the mission.
“We have been very lucky that within the first days of operations we have already been able to observe a developing tropical cyclone.
“The quality of these data reflect the level of testing and preparation that the team has put in prior to launch,” Rodriguez said in a NASA statement. “It also reflects the quality of the spare QuikScat hardware from which RapidScat was partially assembled.”
RapidScat, payload was hauled up to the station as part of the science cargo launched aboard the commercial SpaceX Dragon CRS-4 cargo resupply mission that thundered to space on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida on Sept. 21.
Dragon was successfully berthed at the Earth-facing port on the station’s Harmony module on Sept 23, as detailed here.
It was robotically assembled and attached to the exterior of the station’s Columbus module using the station’s robotic arm and DEXTRE manipulator over a two day period on Sept 29 and 30.
Ground controllers at Johnson Space Center intricately maneuvered DEXTRE to pluck RapidScat and its nadir adapter from the unpressurized trunk section of the Dragon cargo ship and attached it to a vacant external mounting platform on the Columbus module holding mechanical and electrical connections.

The nadir adapter orients the instrument to point at Earth.
The couch sized instrument and adapter together measure about 49 x 46 x 83 inches (124 x 117 x 211 centimeters).
Engineers are in the midst of a two week check out process that is proceeding normally so far. Another two weeks of calibration work will follow.
Thereafter RapidScat will begin a mission expected to last at least two years, said Steve Volz, associate director for flight programs in the Earth Science Division, NASA Headquarters, Washington, at a prelaunch media briefing at the Kennedy Space Center.
RapidScat is the forerunner of at least five more Earth science observing instruments that will be added to the station by the end of the decade, Volz explained.
The second Earth science instrument, dubbed CATS, could be added by year’s end.
The Cloud-Aerosol Transport System (CATS) is a laser instrument that will measure clouds and the location and distribution of pollution, dust, smoke, and other particulates in the atmosphere.
CATS is slated to launch on the next SpaceX resupply mission, CRS-5, currently targeted to launch from Cape Canaveral, FL, on Dec. 9.

This has been a banner year for NASA’s Earth science missions. At least five missions will be launched to space within a 12 month period, the most new Earth-observing mission launches in one year in more than a decade.
ISS-RapidScat is the third of five NASA Earth science missions scheduled to launch over a year.

As the Rosetta spacecraft drops a bit closer to its target comet, some really cool features are popping into view. For example, look at this picture of a 150-foot (45-meter) rock on Comet 67P/Churyumov-Gerasimenko, which was taken in September and released today (Oct. 9). And it’s led to the decision to have an Egyptian theme to naming features on the comet.
“It stands out among a group of boulders in the smooth region located on the lower side of 67P/C-G’s larger lobe,” ESA stated in a release. “This cluster of boulders reminded scientists of the famous pyramids at Giza near Cairo in Egypt, and thus it has been named Cheops for the largest of those pyramids, the Great Pyramid, which was built as a tomb for the pharaoh Cheops (also known as Kheops or Khufu) around 2550 BC.”
Scientists are still trying to figure out what the boulders are made of, and how they are formed, as the spacecraft moves into a “close observation phase” tomorrow (Oct. 10) where it is only 10 kilometers (6.2 miles) from the surface.

Meanwhile, some new results are coming from an asteroid that the spacecraft whizzed by a couple of years ago. In the picture below, you can see evidence of a crater that Rosetta didn’t even see!
The grooves you see there on Lutetia (which Rosetta imaged in 2010) hint at shock waves from various craters, including one that was likely on the hidden side of the asteroid relative to Rosetta as it flew by. The suspected crater is called “Suspicio.” While craters have been found in other asteroids visited by spacecraft, grooves are rarer.
“The way in which grooves are formed on these bodies is still widely debated, but it likely involves impacts,” ESA stated. “Shock waves from the impact travel through the interior of a small, porous body and fracture the surface to form the grooves.”
A paper on the research will be published in Planetary and Space Science this month, led by Sebastien Besse, a research fellow at ESA’s Technical Centre. For more information, check out this release from ESA.

After a couple of years of racing towards Mount Sharp (Aeolis Mons), now it’s time for the Curiosity rover to get a better look at its Martian surroundings. The rover has reached its stated science destination and mission planners say now is the time to stop the driving and get deep into the science.
NASA is on the hunt for signs of habitability on the Red Planet, and officials hope that the layers of this big mountain will yield a wealth of information on Martian history.
“This first look at rocks we believe to underlie Mount Sharp is exciting because it will begin to form a picture of the environment at the time the mountain formed, and what led to its growth,” stated Ashwin Vasavada, Curiosity’s deputy project scientist in a press release from late September.
As Curiosity drills and analyzes rocks at its feet, it continues to send back stunning pictures of its surroundings. Check out a sample from this week below.

What are the goals of the Orion EFT-1 mission?
Orion will launch atop a Delta IV Heavy rocket from Space Launch Complex 37 on Cape Canaveral Air Force Station.
The two-orbit, four and a half hour EFT-1 flight around Earth will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years. It will test the avionics and electronic systems inside the Orion spacecraft.

Here’s another breathtakingly glorious view from India’sMars Orbiter Mission (MOM) – her first global 3-D portrait of her new home careening around the Red Planet.
MOM is India’s first deep space voyager to explore beyond the confines of her home planet’s influence and just successfully arrived at the Red Planet after the “history creating” orbital insertion maneuver on Sept. 23/24 following a ten month journey.
This newly released 3-D view from MOM expands upon the initial 2-D global color view of Mars released by the Indian Space Research Organization (ISRO), India’s space agency. See below and detailed in my earlier story – here.
The 3-D image was generated from multiple pictures acquired by MOM’s on-board Mars Color Camera on Sept 28, 2014, from the very high altitude of approximately 74,500 kilometers as the spacecraft orbits Mars.

The images were taken by the tri-color camera as MOM swooped around the Red Planet in a highly elliptical orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km, according to ISRO.
Therefore, the 3-D Red Planet portrait was captured nearly at apoapsis. And being three dimensional, it gives a stereo sense of the huge dust storm swirling over a large swath of the planet’s Northern Hemisphere set against the blackness of space.
Below right is the southern polar ice cap. To see the 3-D effect, whip out your handy pair of left-eye red, right-eye blue color anaglyph glasses.
And while we’re on the subject of spacely 3-D, it’s worth noting that another of humanity’s ground breaking probes currently making news – ESA’s comet hunting Rosetta probe – likewise snapped a glorious 3-D view of Mars way back in 2007, during the brief, but critical, gravity assist slingshot maneuver that flung Rosetta along her vast 10 year path through interplanetary space.
So by way of comparison let’s take a trip down memory lane and be sure to look back at Rosetta’s global 3-D Martian views (below) taken by the high resolution OSIRIS camera on 24 February 2007 at 19:28 CET from a distance of about 240,000 kilometers.

The $73 million MOM mission is expected to last at least six months.
MOM’s success follows closely on the heels of NASA’s MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21 and could last 10 years or more.
