We’ve done a major update to our Phases of the Moon app for iPhone/iPad and Android, finally fulfilling the most requested feature: a Lunar Atlas.
You can now pinch-zoom the Moon and two-finger pan it around. As you zoom the Moon beyond a certain size, labels for lunar features will appear, like major craters, Apollo landing sites and lunar seas (mare). As you zoom in more, smaller features become visible. Now that we’ve figured out how to actually implement this functionality, we’ll keep improving it, to make Phases of the Moon a really handy tool for stargazing, especially when you’re using a telescope.
There are lots of other features we’ve recently added including: total lunar eclipses, Live Wallpaper and Widgets (for Android), social sharing, and more.
In the ultimate example of science imitating art, engineers working with NASA’s Lunar Reconnaissance Orbiter recently beamed an image of the Mona Lisa to the LRO and back via laser beam in order to measure the rate of transmission between the spacecraft and Earth. This allowed them to then calibrate their software to correct for any discrepancies between the image sent and the one received, resulting in a picture-perfect result.
Leonardo would definitely have approved.
From NASA’s Goddard Space Flight Center:
As part of the first demonstration of laser communication with a satellite at the moon, scientists with NASA’s Lunar Reconnaissance Orbiter (LRO) beamed an image of the Mona Lisa to the spacecraft from Earth.
The iconic image traveled nearly 240,000 miles in digital form from the Next Generation Satellite Laser Ranging (NGSLR) Station at NASA’s Goddard Space Flight Center in Greenbelt, MD, to the Lunar Orbiter Laser Altimeter (LOLA) instrument on the spacecraft. By transmitting the image piggyback on laser pulses that are routinely sent to track LOLA’s position, the team achieved simultaneous laser communication and tracking.
“This test, and the data obtained from it, sets the stage for future high data-rate laser communications demonstrations that will be an essential feature of NASA’s next Moon mission: the Lunar Atmosphere and Dust Environment Explorer.“
Nearly 200 000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy. As the Milky Way’s gravity gently tugs on its neighbour’s gas clouds, they collapse to form new stars. In turn, these light up the gas clouds in a kaleidoscope of colours, visible in this image from the NASA/ESA Hubble Space Telescope.

New computer wallpaper alert. Light from the Large Magellanic Cloud takes nearly 200,000 years to travel to Earth. And it’s worth the wait.

I’ve been waiting for this! We’ve featured previous timelapse videos by Dustin Farrell, and here is part three of his “Landscapes” video series showing stunning views of Earth and sky. This is really gorgeous. Watching in HD with a big screen is recommended.
On Vimeo, Dustin writes that this is the final volume in this series, at least for a while. “I hope you have enjoyed my work on this series over the last three years,” he wrote. “It has been an amazing ride full of amazing experiences. I plan to continue shooting landscapes timelapses but putting together videos of this magnitude will be difficult to continue on a regular basis.”
The Orion spacecraft has gotten a new look for its first launch atop the inaugural flight of NASA’s Space Launch System (SLS) booster on the Exploration Mission-1 flight around the Moon in 2017 as seen in this new animation.
The vehicles service module will be built by the European Space Agency (ESA), as a result of a new bilateral agreement between NASA and ESA. Orion is designed to carry humans back to the Moon and to deep space destinations like Asteroids and Mars.
The service module will fuel and propel the capsule on its uncrewed journey to the Moon and back on EM-1 in 2017.
Read my follow-up report for details about the new NASA/ESA agreement. See my earlier story here, about preparations for the first Orion launch in September 2014 on the upcoming Exploration Flight Test-1 in 2014 atop a Delta IV Heavy. An unmanned Orion will fly on a two orbit test flight to an altitude of 3,600 miles above Earth’s surface, farther than a human spacecraft has gone in 40 years, and then plunge back to Earth to test the spacecrafts systems and heat shield.
NASA is also simultaneously fostering the development of commercial ‘space taxis’ to fly astronauts to the International Space Station (ISS) as part of a dual track approach to restore America’s human space launch capability. The 1st commercial crew vehicle might fly as early as 2015 – details here.

This week, scientists at NASA released their global climate analysis for 2012 which revealed that Earth continues to experience warmer temperatures than several decades ago. The past year was the ninth warmest year on record since 1880, continuing what appears to be a long-term global trend of rising temperatures. The ten warmest years in the 132-year record have all occurred since 1998, and the last year that was cooler than average was 1976. The hottest years on record were 2010 and 2005.
The analysis was done by NASA’s Goddard Institute for Space Studies (GISS) which monitors global surface temperatures on an ongoing basis, comparing temperatures around the globe to the average global temperature from the mid-20th century.
In 2012, the average temperature was about 14.6 degrees Celsius (58.3 degrees Fahrenheit). This is .55 degrees C (1.0 degree F) warmer than the mid-20th century baseline, with the global average temperature having risen about 0.8 degrees C (1.4 degrees F) since 1880. The majority of that change has occurred in the past forty years.
Additionally, last week the US National Climatic Data Center (NCDC) released their latest climate report from 2012 and found that it was the warmest year ever recorded in the contiguous United States. The average temperature for the contiguous United States for 2012 was 13 degrees C (55.3 degrees F) which was 3.2°F above the 20th century average.
The map depicts temperature anomalies, or changes, by region in 2012; while the line plot above shows yearly temperature anomalies from 1880 to 2011 as recorded by NASA GISS, the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center, the Japanese Meteorological Agency, and the Met Office Hadley Centre in the United Kingdom. NASA Goddard Institute for Space Studies.
The data was gathered by NASA GISS, the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center, the Japanese Meteorological Agency, and the Met Office Hadley Centre in the United Kingdom. All four institutions tally temperature data from stations around the world and make independent judgments about whether the year was warm or cool compared to other years. Though there are minor variations from year to year, all four records show peaks and valleys in sync with each other. All show rapid warming in the past few decades, and all show the last decade as the warmest.
Scientists emphasize that weather patterns cause fluctuations in average temperatures from year to year, but the continued increase in greenhouse gas levels in the atmosphere assures that there will be a long-term rise in global temperatures. Each individual year will not necessarily be warmer than the previous year, but scientists expect each decade to be warmer than the previous decade.
“One more year of numbers isn’t in itself significant,” GISS climatologist Gavin Schmidt said. “What matters is this decade is warmer than the last decade, and that decade was warmer than the decade before. The planet is warming. The reason it’s warming is because we are pumping increasing amounts of carbon dioxide into the atmosphere.”
See an interactive global temperature map from New Scientist.
Carbon dioxide traps heat and largely controls Earth’s climate. It occurs naturally but is also released by the burning of fossil fuels for energy. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades, largely driven by increasing man-made emissions. The carbon dioxide level in the atmosphere was about 285 parts per million in 1880, the first year of the GISS temperature record. By 1960, the atmospheric carbon dioxide concentration, measured at NOAA’s Mauna Loa Observatory, was about 315 parts per million. Today, that measurement exceeds 390 parts per million.
The continental U.S. endured its warmest year on record by far, according to NOAA, the official keeper of U.S. weather records. NOAA also announced that global temperatures were 10th warmest on record by their analysis methods.
“The U.S. temperatures in the summer of 2012 are an example of a new trend of outlying seasonal extremes that are warmer than the hottest seasonal temperatures of the mid-20th century,” NASA GISS director James E. Hansen said. “The climate dice are now loaded. Some seasons still will be cooler than the long-term average, but the perceptive person should notice that the frequency of unusually warm extremes is increasing. It is the extremes that have the most impact on people and other life on the planet.”

More details have emerged on NASA’s plan to add the first commercial module to the International Space Station, an inflatable room built by Bigelow Aerospace. The Bigelow Expandable Activity Module (BEAM), which is scheduled to arrive at the space station in 2015 for a two-year technology demonstration. It will be delivered by another commercial company, SpaceX, on what is planned to be the eighth cargo resupply mission too the ISS for Dragon and the Falcon 9 rocket. Astronauts will use the station’s robotic arm to install the module on the aft port of the Tranquility node. NASA Deputy Administrator Lori Garver announced Wednesday NASA has awarded a $17.8 million contract to Bigelow Aerospace for BEAM.
“Today we’re demonstrating progress on a technology that will advance important long-duration human spaceflight goals,” Garver said. “NASA’s partnership with Bigelow opens a new chapter in our continuing work to bring the innovation of industry to space, heralding cutting-edge technology that can allow humans to thrive in space safely and affordably.”
BEAM is a cylindrical module, like all other ISS modules, and is about somewhat similar in size to the US Harmony module, as BEAM is about 4 meters (13 feet) long and 3.2 meters (10.5 feet) wide; Harmony 7.2 meters (24 ft) in length, and it has a diameter of 4.4 meters (14 ft). But weight is where the two vastly differ: Harmony weighs in 14,288 kilograms (31,500 lb), while BEAM weighs roughly 1,360 kg (3,000 pounds). And that is the big advantage of inflatable structures for use in space: their mass and volume are relatively small when launched, reducing launch costs.

Leonard David reports on Space.com that the BEAM module should be much quieter than the other modules due to the non-metallic nature of the structure.
After the module is berthed to the Tranquility node, the station crew will activate a pressurization system to expand the structure to its full size using air stored within the packed module.
During the two-year test period, station crew members and ground-based engineers will gather performance data on the module, including its structural integrity and leak rate. An assortment of instruments embedded within module also will provide important insights on its response to the space environment. This includes radiation and temperature changes compared with traditional aluminum modules.
BEAM will also be assessed for future habitats for long-duration space missions, said Bill Gerstenmaier, associate administrator for human exploration and operations at NASA.
Watch how the BEAM module will be attached and inflated:
Astronauts periodically will enter the module to gather performance data and perform inspections. Following the test period, the module will be jettisoned from the station, and will burn up on re-entry.
Bigelow Aerospace says the BEAM 330 module can function as an independent space station, or several of the inflatable habitats can be connected together in a modular fashion to create an even larger and more capable orbital space complex.
Bigelow also lists their radiation shielding as equivalent to or better than the other modules on the International Space Station and substantially reduces the dangerous impact of secondary radiation, while their innovative Micrometeorite and Orbital Debris Shield “provides protection superior to that of the traditional ‘aluminum can’ designs, according to the Bigelow Aerospace website.

You’ve probably seen plenty of photos of astronauts and cosmonauts working aboard the International Space Station, and maybe even some videos of ISS briefings and interviews and tours throughout the different modules (and perhaps even an astronaut-produced song or two.) But have you ever wondered what the average, everyday sounds inside Station are like?
If so, Canadian astronaut and Expedition 34 flight engineer Chris Hadfield has an earful for you.
To share his ISS experience past mere pixels, Hadfield has posted some recordings on Soundcloud taken from various locations around Station, giving an idea of the many ambient noises found inside humanity’s orbiting “place in space.” (But if you think it sounds anything like the bridge of the U.S.S. Enterprise, you may be in for a surprise.)
Here’s just a few of the recordings Hadfield has posted (you’ll have to click each to play in Soundcloud):
So even though life on the ISS might not sound like what you’d first imagine in a spaceship or have a dramatic score to accompany its soaring adventures around the world, it certainly has a unique sound all its own (and sometimes the astronauts do get to add their own original soundtrack too.)
Chris may have founded a new music genre: “Space Folk”

Look closely and see where the Curiosity rover has been roving about inside Gale Crater on Mars, from “Bradbury Landing” to its current location in “Yellowknife Bay.” This shot was taken by the HiRISE camera on board the Mars Reconnaissance Orbiter on January 2, 2013.
“This image shows the entire distance traveled from the landing site (dark smudge at left) to its location as of 2 January 2013 (the rover is bright feature at right),” wrote HiRISE principal investigator Alfred McEwen on the HiRISE website. “The tracks are not seen where the rover has recently driven over the lighter-toned surface, which may be more indurated [hardened] than the darker soil.”
You can compare this image to one taken on September 8, 2012 to see how much the rover has driven in Gale Crater:

And here’s a map of Curiosity’s travels that NASA released yesterday:
Mission scientists said at a briefing yesterday (January 15, 2013) that between Sol (Martian day) 120 and Sol 121 of the mission — which equates to Dec. 7 and Dec. 8, 2012 — Curiosity crossed over a terrain boundary into lighter-toned rocks that correspond to high thermal inertia values observed by NASA’s Mars Odyssey orbiter. The green dashed line marks the boundary between the terrain types.
The inset graphs the range in ground temperature recorded each day by the Rover Environmental Monitoring Station (REMS) on Curiosity. Note that the arrival onto the lighter-toned terrain corresponds with an abrupt shift in the range of daily ground temperatures to a consistently smaller spread in values. This independently signals the same transition seen from orbit, and marks the arrival at well-exposed, stratified bedrock.
Sol 124 (Dec. 11, 2012) marked the arrival into an area called “Yellowknife Bay,” where sulfate-filled veins and concretions were discovered, along with much finer-grained sediments providing evidence of past water interacting with the surface.
Here’s the Mars weather report provided by REMS for Sol 158 (January 15, 2013):

Astronauts on the International Space Station today are installing a new modified Celestron telescope. This won’t be used to observe the stars, but instead look back to Earth to acquire imagery of specific areas of the world for disaster analysis and environmental studies. Called ISERV (International Space Station SERVIR Environmental Research and Visualization System), it is a new remote-controlled imaging system.
“Essentially, it will be pointed out of one of the windows of the Space Station, and used for Earth imaging,” Andrea Tabor, social media coordinator for Celestron told Universe Today, “especially for natural disasters and to help countries that may not have their own Earth-observing satellites to help assess damage and assist with evacuations.”
ISERV will be installed in the Window Observational Research Facility (WORF) in the station’s Destiny laboratory.
The Celestron CPC 925, is a 9.25″ diffraction limited Schmidt-Cassegrain telescope and off-the-shelf sells for $2,500 including the mount, (just the 9.25 inch optical tube sells for $1,479). It was modified at the Marshall Space Flight Center.
“They used the fork mount that comes with it,” Tabor said, “but they just removed the tripod and replaced it with a specialized mount to anchor and stabilize it on the ISS.”
Because it is pointed out of a window and because the ISS is moving so fast, it would be difficult to align it with the sky and do any celestial imaging, Tabor said.
ISERV is the first of what is hoped to be a series of space station Earth-observing instruments, each to feature progressively more capable sensors to help scientists gain operational experience and expertise, as well as help design better systems in the future. Scientists envision that future sensors could be mounted on the exterior of the station for a clearer, wider view of Earth.
It arrived on the ISS in July of 2012 on board the Japanese HTV-3.
“It’s been up there sitting in a box, so today was unboxing and assembly day,” Tabor said. She added that they hope to post some of the first images from the telescope on their Twitter and Facebook pages.
The telescope will normally be operated by remote-controlled from Earth and so the astronauts won’t likely be working with it directly except for assessing its operation or troubleshooting any problems.
“Images captured from ISERV on the ISS could provide valuable information back here on Earth,” said Dan Irwin, SERVIR program director at Marshall. “We hope it will provide new data and information from space related to natural disasters, environmental crises and the increased effects of climate variability on human populations.”
