Observers in Australia and New Zealand had a special treat this week: watching Saturn disappear behind the Moon during an event called an occultation. (You can read all the details of how and why this happens here in our preview article.) Catching an event like this with a camera is tricky… the bright Moon can wash out the comparatively tiny (from our vantage point) planet Saturn. But here, several astrophotographers had success. Above is a nice view from Silveryway on Flickr.

Peter Lake, also from Australia not only took images of the event, but also did a live Hangout on G+.
“Live hangouts and driving a telescope live is a tricky business,” Peter wrote on his website. “I lost focus playing around trying to improve the image due to the thin cloud.” He added that the night sky wasn’t ideal that evening. “The full moon was shining through thin clouds, washing out a bit of the detail.”

Where did Mars’ moons Phobos and Deimos come from? How did they end up in orbit around Mars? This cool video from the folks at Kurzgesagt answers the most-oft asked questions about these mini moons.
You should also check out their other wonderful videos, like the one about our own Moon, below, which explains how big our Moon really is. The answer might surprise you.

Funny thing. Skywatchers are often just as excited to watch a celestial object disappear as we are to see it make an appearance. Early Wednesday morning (May 14) the Full Flower Moon will slip in front of Saturn, covering it from view for about an hour for observers in Australia and New Zealand. If you don’t live where the dingoes roam, no worries. You can watch it online.And no matter where you are on the planet, the big moon will accompany the ringed planet across the sky this Tues. night-Weds. morning.
Moon-Saturn occultation from Perth, Australia Feb. 22, 2014 captured by Colin Legg
Occultations of stars happen swiftly. The moon’s limb meets the pinpoint star and bam! it’s gone in a flash. But Saturn is an extended object and the moon needs time to cover one end of the rings to the other. Planetary occultations afford the opportunity to remove yourself from planet Earth and watch a planet ‘set’ and ‘rise’ over the alien lunar landscape. Like seeing a Chesley Bonestell painting in the flesh.
Saturn and the moon Tuesday night (May 13) just before midnight as viewed from the U.S. Stellarium
As the moon approaches Saturn, the planet first touches the lunar limb and then appears to ‘set’ as it’s covered by degrees. About an hour later, the planet ‘rises’ from the opposite limb. Planetary occultations are infrequent and always worth the effort to see.
Seen from the northern hemisphere and equatorial regions, the nearly full moon will appear several degrees to the right or west of Saturn tomorrow night (May 13). As the night deepens and the moon rolls westward, the two grow closer and closer. They’ll be only a degree apart (two full moon diameters) during Wednesday morning twilight seen from the West Coast. Northern hemisphere viewers will notice that the moon slides to the south of the planet overnight.

Skywatchers in Australia will see the moon cover Saturn during convenient early evening viewing hours May 14:
* 8:09 p.m. local time from Adelaide
* 9:05 p.m. Brisbane
* 8:50 p.m. Melbourne
* 8:53 p.m. Canberra
* 8:56 p.m. from Sydney (More times and a map – click HERE)
Before the occultation, Saturn will shine close to the moon’s upper right and might be tricky to see with the naked eye because of glare.
Binoculars will easily reveal the planet, but a telescope is the instrument of choice. Even a small scope magnifying at least 30x will show Saturn and its rings hovering above the bright edge of the moon. Stick around. About an hour later, Saturn will re-emerge along the moon’s lower left limb.
Saturn and its moons Tuesday night May 13 around 10 p.m. CDT. Titan’s the brightest and easiest moon to see at magnitude +8.5. Iapetus ranges from magnitude +10 when it’s west of Saturn and we see its bright hemisphere to magnitude +12 when it’s east of the planet. Created with Meridian software
Meanwhile, back in the western hemisphere, we’ll watch the nearly full Flower Moon make a close pass of the planet. If you’ve had difficulty finding the celestial ring bearer, you’ll have no problem Tuesday night. Take a look at Saturn’s wonderful system of rings in your telescope – they’re tipped nearly wide open this year. For even more fun, see how many moons you can spot. And don’t forget, you can watch it online courtesy of astrophysicist Gianluca Masi. His Virtual Telescope website will broadcast the occultation live starting at 10:15 Universal Time May 14 (6:15 a.m. EDT, 5:15 CDT, 4:15 MDT and 3:15 PDT).

That’s Earth. That’s us. Way off in the distance as a fairly small, blue and swirly white sphere. This is the newest so-called “Earthrise” image, and it was taken on February 1, 2014 by the Lunar Reconnaissance Orbiter.
“LRO experiences twelve earthrises every day, however LROC is almost always busy imaging the lunar surface so only rarely does an opportunity arise such that LROC can capture a view of the Earth,” wrote LROC Principal Investigator Mark Robinson on the instrument’s website. “On the first of February of this year LRO pitched forward while approaching the north pole allowing the LROC WAC to capture the Earth rising above Rozhdestvenskiy crater (180-km diameter).”
Robinson went on to explain that the Earth is a color composite from several frames and the colors are very close to what the average person would see if they were looking back at Earth themselves from lunar orbit. “Also, in this image the relative brightness between the Earth and the Moon is correct, note how much brighter the Earth is relative to the Moon,” Robinson said.
Gorgeous.
Below is a gif image that demonstrates how images are combined over several orbits to create a full image from the Wide Angle Camera.

The frames were acquired at two second intervals, so the total time to collect the sequence was 5 minutes. The video is faster than reality by a factor of about 20.

Striking a Buzz Lightyear-like pose above is the winning design for NASA’s Z-2 spacesuit prototype. The version, called “technology”, was by far the popular vote in an online contest the agency held to choose between three prototypes, garnering 62% of 233,431 votes.
While this will never be used in space, NASA said the next-generation prototype will be useful in helping design future spacesuits. And this prototype will go through a “test campaign” that includes vacuum tests, pool tests in NASA’s Neutral Buoyancy Laboratory and in an area at the Johnson Space Center that simulates the surface of Mars.
“With the agency laser focused on a path to Mars, work to develop the technologies astronauts one day will use to live and work on Mars has already begun. Each iteration of the Z-series will advance new technologies that one day will be used in a suit worn by the first humans to step foot on the Red Planet,” NASA stated.
To learn more about the suit and the differences from its predecessor, the Z-1, check out this recent Universe Today article.

Fly me — or my package — to the Moon? “Anything is possible!” said astrophotographer Sebastien Lebrigand, via email to Universe Today. Lebrigand lives along the flight path to the Charles de Gaulle Airport in Paris and regularly takes images of planes flying in front of the Moon, (see another of his shots here), but he’s thinking this might be his best one yet.
He used a 102/660 mm refractor telescope with a Canon EOS60d camera to capture this shot.

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) literally ‘saw the light’ just days before crashing into the lunar farside last Thursday April 17. Skimming just a few kilometers above the moon’s surface, mission controllers took advantage of this unique low angle to gaze out over the moon’s horizon in complete darkness much like the Apollo astronauts did from lunar orbit more than 40 years ago.

With the glow of Earth well-hidden, any dust in the moon’s scant atmosphere around the time of orbital sunrise should become visible. Scientists also expected to see the softly luminous glow of the zodiacal light, an extensive cloud of comet and asteroid dust concentrated in the flat plane of the solar system. The zodiacal light gets its name from the zodiac, that familiar band of constellations the planets pass through as they orbit the sun. Back on Earth, the zodiacal light looks like a big thumb of light standing up from the western horizon a couple hours after sunset in spring and before sunrise in fall.

So what did LADEE see? As you watch the animation above, comprised of images taken from darkness until sunrise, you’ll see a yellow haze on the horizon that expands into large diffuse glow tilted slightly to the right. This is the zodiacal light along with a smaller measure of light coming from sun’s outer atmosphere or corona. Together they’re referred to as CZL or ‘coronal and zodiacal light’. At the very end, the sun peaks over the lunar horizon.
This is a sketch of the lunar sunrise seen from orbit by Apollo 17 astronaut Eugene Cernan. On the right, the sketches are highlighted in color to show the sources of the scattered light: red indicates coronal and zodiacal light (CZL), blue is a glow along the lunar horizon possibly caused by dust suspended in the moon’s exosphere, and green may be crepuscular rays formed by shadowing and scattered light.

What appears to be missing from the pictures are the mysterious rays seen by some of the Apollo astronauts. The rays, neatly sketched by astronaut Eugene Cernan of Apollo 17, look a lot like those beams of light and shadow streaming though holes in clouds called crepuscular rays.

Only thing is, Earth’s atmosphere is thick enough for cloud beams. The dust in the moon’s atmosphere appears much too thin to cause the same phenomenon. And yet the astronauts saw rays as if sunlight streamed between mountain peaks and scattered off the dust just like home.

It’s believed that dust gets lofted into the spare lunar atmosphere via electricity. Ultraviolet light from the sun knocks electrons from atoms in moon dust, giving them a positive charge. Since like charges repel, bits of dust push away from one another and move in the direction of least resistance: up. The smaller the dust particle, the higher it rises until dropping back down to the surface. Perhaps these “fountains” of lunar dust illuminated by the sun are what the astronauts recorded.
Unlike Cernan, LADEE saw only the expected coronal and zodiacal light but no rays. Scientists plan to look more closely at several sequences of images made of lunar sunrise in hopes of finding them.

The space community lost a colossus of the of the Apollo era last week, when John Houbolt passed away last Tuesday just five days after his 95th birthday.
Perhaps the name isn’t as familiar to many as Armstrong or Von Braun, but John Houbolt was a pivotal figure in getting us to the Moon.
Born in Altoona, Iowa on April 10th, 1919, Houbolt spent most of his youth in Joliet, Illinois. He earned a Masters degree in Civil Engineering from the University of Illinois at Urbana-Champaign in 1942 and a PhD in Technical Sciences from ETH Zurich in Switzerland in 1957. But before that, he would become a member of the National Advisory Committee for Aeronautics (NACA) in 1942, an organization that would later become the National Aeronautics and Space Administration or NASA in 1958.
It was 1961 when Houbolt made what would be his most enduring mark on the space program. He was working as an engineer at the Langley Research Center, at a time when NASA and the United States seriously needed a win in the space race. The U.S.S.R. had enjoyed a long string of firsts, including first satellite in orbit (Sputnik 1, October 1957), first spacecraft to photograph the lunar farside (Luna 3 in October 1959) and first human in space with the launch of Yuri Gagarin aboard Vostok 1 in April 1961. A young President Kennedy would make his now famous “We choose to go to the Moon…” speech at Rice University later the next year in late 1962. Keep in mind, in U.S. astronaut John Glenn had just made his first orbital flight months before Kennedy’s speech, and total accumulated human time in space could be measured in mere hours. Unmanned Ranger spacecraft were having a tough time even getting off of the pad, and managing to crash a space probe into the Moon was considered to be a “success”. The task of sending humans “by the end of this decade” was a daunting one indeed…
NASA would soon have a mandate to sent humans to the Moon: but how could they pull it off?
Early ideas for manned lunar missions envisioned a single gigantic rocket that would head to the Moon and land, Buck Rodgers style, “fins first.” Such a rocket would have to be enormous, and carry the fuel to escape Earth’s gravity well, land and launch from the Moon, and return to Earth.
A second approach, known as Earth-orbit rendezvous, would see several launches assemble a mission in low Earth orbit and then head to the Moon. Curiously, though this was an early idea, it was never used in Apollo, though it was briefly resurrected during the now defunct Constellation Program.
Three plans to go to the Moon. Credit: NASA.
But it was a third option that intrigued Houbolt, known as Lunar Orbit Rendezvous. LOR had been proposed by rocket pioneers Yuri Kondratyuk and Hermann Oberth in 1923, but had never been seriously considered. It called for astronauts to depart the Earth in a large rocket, and instead, use a small lander designed only to land and launch from the Moon while the spacecraft for Earth return orbited overhead.
Houbolt became a staunch advocate for the idea, and spent over a year convincing NASA officials. In one famous letter to NASA associate administrator Robert Seamans, Houbolt was known to have remarked “Do we want to go to the Moon or not?”
It’s interesting to note that it was probably only in a young organization like the NASA of the early 1960s that, in Houbolt’s own words, a “voice in in the wilderness” could be heard. Had NASA become a military run organization — as many advocated for in the 1950s — a rigid chain of command could have meant that such brash ideas as Houbolt’s would have never seen the light of day. Thank scientists such as James Van Allen for promoting the idea of a civilian space program that we take for granted today.
Even then, selling LOR wasn’t easy. The idea looked preposterous: astronauts would have to learn how to undock and dock while orbiting a distant world, with no chance of rescue. There was no second chance, no backup option. Early plans called for an EVA for astronauts to enter the Lunar Module prior to descent which were later scrapped in favor of extracting it from atop the third stage and boarding internally before reaching the Moon.
Once Houbolt had sold key visionaries such as Wernher von Braun on the idea in late 1962, LOR became the way we would go to the Moon. And although Houbolt’s estimations of the mass required for the Lunar Module were off by a factor of three, the story is now the stuff of early Apollo era legend. You can see Houbolt (played by Reed Birney) and the tale of the LM and LOR in the From Earth to the Moon episode 5 entitled “Spider”.

Houbolt was awarded NASA’s medal for Exceptional Scientific Achievement in 1963, and he was in Mission Control When Apollo 11 touched down in the Sea of Tranquility.
He passed away in a Scarborough, Maine nursing home last Tuesday, and joins other unsung visionaries of the early space program such as Mary Sherman Morgan. It’s sad to think that we may soon live in a world where those who not only walked on the Moon, but those who also sent us and knew how to get there, are no longer with us.

NASA’s LADEE lunar orbiting dust and atmosphere explorer probe has bitten the dust and crashed into the Moon’s surface exactly as planned following a fabulously successful and groundbreaking science mission that exceeded all expectations.
The Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft impacted the far side of the Moon sometime overnight between 12:30-1:22 a.m. EDT, Friday, April 18 (9:30 and 10:22 p.m. PDT, Thursday, April 17) according to a NASA statement.
Running low on fuel and unable to continue any further science observations, the couch sized spacecraft was intentionally plunged into the rugged lunar surface at a spot designed to keep it far away from disturbing any of the historic Apollo manned lunar landing sites or unmanned surveyors on the Moon’s near side.
Mission controllers at NASA’s Ames Research Center allowed LADEE’s orbit to naturally decay following the conclusion of the probes extended mission in the final low orbit science phase.
The probe was likely smashed violently to smithereens and mostly vaporized from the heat generated upwards of several hundred degrees. Any surviving debris may be buried in shallow crater formed by the impact.
“At the time of impact, LADEE was traveling at a speed of 3,600 miles per hour – about three times the speed of a high-powered rifle bullet,” said Rick Elphic, LADEE project scientist at Ames, in a NASA statement.
“There’s nothing gentle about impact at these speeds – it’s just a question of whether LADEE made a localized craterlet on a hillside or scattered debris across a flat area. It will be interesting to see what kind of feature LADEE has created.”
The powerful NAC telescopic camera aboard NASA’s still orbiting Lunar Reconnaissance Orbiter (LRO) will be directed in coming months to try and photograph the impact site after engineers pinpoint the likely crash site.

After completing its primary science mission in March, the already ultra low altitude of the lunar orbiting probe was reduced even further so that it was barely skimming just 2 kilometers (1 mile) above the pockmarked lunar surface.
Such a low altitude thus enabled LADEE to gather unprecedented science measurements of the Moon’s extremely tenuous atmosphere and dust particles since the species would be present at a higher concentration.
Lots of fuel is required to maintain LADEE’s orbit due to the uneven nature of the Moon’s global gravity field.
The final engine firing was commanded on April 11 to ensure a far side impact and the safety of all the historic lunar landing sites.
“LADEE also survived the total lunar eclipse on April 14 to 15. This demonstrated the spacecraft’s ability to endure low temperatures and a drain on batteries as it, and the moon, passed through Earth’s deep shadow,” said NASA
LADEE was launched on Sept. 6, 2013 from NASA Wallops in Virginia on a science mission to investigate the composition and properties of the Moon’s pristine and extremely tenuous atmosphere, or exosphere, and untangle the mysteries of its lofted lunar dust dating back to the Apollo Moon landing era.
All those objectives and more were accomplished during its nearly half year investigating Earth’s nearest neighbor.

It entered lunar orbit on Oct. 6, 2013 amidst the ridiculous government shutdown that negatively affected a number of science missions funded across the US federal government.
The science mission duration had initially been planned to last approximately 100 days and finish with a final impact on the Moon on about March 24th.
NASA granted LADEE a month long extension since the residual rocket fuel was more than anticipated due to the expertise of LADEE’s navigation engineers and the precision of the launch atop the Orbital Sciences Minotaur V rocket and orbital insertion.
“It’s bittersweet knowing we have received the final transmission from the LADEE spacecraft after spending years building it in-house at Ames, and then being in constant contact as it circled the moon for the last several months,” said Butler Hine, LADEE project manager at Ames.
The 844 pound (383 kg) robot explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.
The $280 million probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.

The keys to NASA’s historic launch Pad 39A that propelled humanity’s first man to walk on the Moon – Neil Armstrong – during the history making flight of Apollo 11, have been handed over to new owners, namely the private aerospace firm SpaceX for a new purpose – serving as a commercial launch facility.
NASA and Space Exploration Technologies Corporation (SpaceX) of Hawthorne, Calif., have just signed an agreement giving SpaceX rights to occupy and operate seaside Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.
SpaceX was founded by billionaire, entrepreneur and space visionary Elon Musk.
SpaceX aims to give the now dormant pad a new lease on life in the emerging New Space era by revitalizing it as a commercial launch site for the company’s mammoth new Falcon Heavy rocket, currently under development, as well as for manned launches of the firm’s human rated Dragon spacecraft atop the Falcon 9 according to Gwynne Shotwell, president of SpaceX.
“We’ll make great use of this pad, I promise,” Shotwell told reporters at a briefing at the pad.
The liquid fueled Falcon Heavy will be the most powerful rocket in the world according to SpaceX, generating generating nearly four million pounds of liftoff thrust from 27 engines and thus significantly exceeding the power of the Delta IV Heavy manufactured by competitor United Launch Alliance.
Shotwell said renovations to pad 39A would start later this year. The maiden SpaceX launch from the complex is expected next year.
“We will launch the Falcon Heavy from here from this pad early next year,” Shotwell stated.

The SpaceX Dragon is one of three commercial crew vehicles being developed under a public-private partnership with NASA to ferry US astronauts to the International Space Station (ISS) and restore America’s human spaceflight capability lost since the shuttle’s retirement.
The Boeing CST-100 and Sierra Nevada Dream Chaser are also vying for the next round of private ‘space taxi’ funding from NASA.
Pad 39A has been inactive and mothballed since the last shuttle mission, STS-135, thundered to space in July 2011.
Not a single rocket has rolled up the ramp at KSC in nearly 3 years.

The new lease agreement was signed by NASA and SpaceX officials and announced onsite at Pad 39 at the briefing.
“Today this historic site from which numerous Apollo and space shuttle missions began and from which I first flew and left the planet on STS-61C on Columbia, is beginning a new mission as a commercial launch site,” said NASA Administrator Charles Bolden.
“While SpaceX will use pad 39A at Kennedy, about a mile away on pad 39B, we’re preparing for our deep space missions to an asteroid and eventually Mars. The parallel pads at Kennedy perfectly exemplify NASA’s parallel path for human spaceflight exploration — U.S. commercial companies providing access to low-Earth orbit and NASA deep space exploration missions at the same time.”
Under terms of the new agreement with NASA, the lease with SpaceX spans 20 years.
“It’s exciting that this storied NASA launch pad is opening a new chapter for space exploration and the commercial aerospace industry,” said Bolden.
SpaceX will also maintain and operate Pad 39A at its own expense, with no US federal funding from NASA.
Pad 39A will be SpaceX’s third launch site. The company also launches its Falcon 9 rockets from nearby Pad 40 on Cape Canaveral Air Force Station and a west coast pad on Vandenberg Air Force Base, Calif.

The next Falcon 9 liftoff with an unmanned Dragon cargo freighter is currently slated from Friday, April 18 following Monday’s scrub.
NASA determined that the agency no longer has a use for pad 39A since the end of the shuttle era and has been looking for a new tenant to take over responsibility and pay for maintenance of the launch complex. The agency awarded the lease to SpaceX in December 2013.
Instead, NASA decided to completely upgrade, renovate and modernize Pad 39As twin, namely Launch Pad 39B, and invested in converting it into a 21st Century launch complex.
NASA will use Pad 39B to launch the state of the art Orion crew vehicle atop the new Space Launch System (SLS) booster for voyages beyond Earth and taking humans back to the vicinity of the Moon and further out on deep space missions to Asteroids, Mars and beyond.
The first unmanned SLS test flight from Pad 39B is slated for late 2017.
Pad 39A was an active NASA launch pad for nearly 35 years starting back near the dawn of the Space Age in the 1960s.

Apollo 4 was the first NASA booster to blast off from Pad 39A on Nov. 9, 1967 during the historic inaugural test flight of the Saturn V moon rocket that eventually served to dispatch all six US manned lunar landing missions.
The closing NASA use of Pad 39A took place on July 8, 2011 with the launch of STS-135 and orbiter Atlantis on the final flight of the space shuttle era.
The four person STS-135 crew delivered the last US pressurized module to the massive low-Earth orbiting ISS.
No Americans have launched to space from American soil since STS-135.
Launch Complex 39 was originally constructed to launch the Apollo moon landing missions atop NASA’s Saturn V booster in the 1960s and 1970s. Both pads were later modified to support the Space Shuttle program whose first launch took place in 1981 from pad 39A.
“Kennedy Space Center is excited to welcome SpaceX to our growing list of partners,” Center Director Bob Cabana said. “As we continue to reconfigure and repurpose these tremendous facilities, it is gratifying to see our plan for a multi-user spaceport shared by government and commercial partners coming to fruition.”
