Earth and Moon imaged from Cassini on July 19, 2013
Did you smile and wave at Saturn on Friday? If you did (and even if you didn’t) here’s how you — and everyone else on Earth — looked to the Cassini spacecraft, 898.4 million miles away.
Hope you didn’t blink!
The image above is a color-composite made from raw images acquired by Cassini in red, green, and blue visible light wavelengths. Some of the specks around the edges are background stars, and others are the result of high-energy particle noise, of which some have been digitally removed.
The Moon is the bright dot just below and to the left of Earth. (An original raw image can be seen here.)
Cassini acquired the images while capturing views of Saturn in eclipse against the Sun between 22:24:00 UTC on July 19 and 02:43:00 UTC on July 20 (6:24 to 10:43 pm EDT July 19.) On Cassini time, the Earth imaging took place between 22:47:13 UTC (6:47:13 pm EDT) and 23:01:56 UTC (7:01:56 pm EDT) on the 19th.

The world was invited to “Wave at Saturn” beginning 5:27 pm EDT on Friday — which allowed enough time for the photons from a waving world to actually reach Cassini’s camera just beyond Saturn, 1.44 billion kilometers away. (Did you wave? I did!) It was the first time Earth’s population was made aware beforehand that their picture would be taken from such a cosmic distance.

The image of our planet and moon, seen as merely a couple of bright points of light against the blackness of space, recalls Sagan’s poignant “pale blue dot” passage from Cosmos…
“From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here, that’s home, that’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”
— Carl Sagan (1934–1996)
A full mosaic of Cassini’s imaging of Saturn silhouetted against the Sun is expected in the coming weeks.

In a fitting testament to NASA’s momentous Apollo Moon Landing Program, NASA and billionaire Jeff Bezos confirmed today (July 19) the discovery of a powerful F-1 first stage engine component from the Saturn V moon rocket that launched three American astronauts on the historic journey of Apollo 11 to land the first two humans on the Moon on July 20, 1969.
“On the eve of the 44th moonwalk anniversary, the Bezos Expedition confirms an Apollo 11 Saturn V F1 engine find,” NASA officially announced on its websites just moments ago today, July 19.
Apollo 11 commander and NASA astronaut Neil Armstrong, was immortalized forever when he first set foot on the moon 44 years ago tomorrow (July 20, 1969), followed minutes later by the lunar module pilot, NASA astronaut Buzz Aldrin.
The Saturn V rockets first stage was powered by a cluster of five F-1 engines – a technological marvel and the most powerful single-nozzle, liquid-fueled rocket engine ever developed.
“44 years ago tomorrow Neil Armstrong stepped onto the moon, and now we have recovered a critical technological marvel that made it all possible,” says Bezos on his Expedition website today.

Bezos, founder and Chief Executive Officer of the aerospace company Blue Origin and Amazon.com, originally announced the discovery and recovery of significant components of two flown F-1 engines amongst a field of twisted wreckage from the floor of the Atlantic Ocean in March of this year, aboard the Seabed Worker at Port Canaveral, Florida, along with a treasure trove of other major Saturn V components hauled up from a depth of almost 3 miles.
“We brought back thrust chambers, gas generators, injectors, heat exchangers, turbines, fuel manifolds and dozens of other artifacts – all simply gorgeous and a striking testament to the Apollo program,” wrote Bezos in a update this morning, July 19.
But until today, the engines exact identification remained elusive because of decades of severe seabed corrosion and their fiery, destructive end upon plunging and smashing unimpeded onto the ocean’s surface.

Conservators from the Kansas Cosmosphere and Space Center in Hutchinson, Kansas worked painstakingly since March to identify the F-1 engine parts.
“Today, I’m thrilled to share some exciting news. One of the conservators who was scanning the objects with a black light and a special lens filter has made a breakthrough discovery – “2044” – stenciled in black paint on the side of one of the massive thrust chambers, says Bezos.
“2044 is the Rocketdyne serial number that correlates to NASA number 6044, which is the serial number for F-1 Engine #5 from Apollo 11. The intrepid conservator kept digging for more evidence, and after removing more corrosion at the base of the same thrust chamber, he found it – “Unit No 2044” – stamped into the metal surface.”

Apollo 11 launched to the Moon on July 16, 1969 from Launch Complex 39-A at the Kennedy Space Center in Florida.
Armstrong and Aldrin landed on the Sea of Tranquility inside the Lunar Module. They took a single lunar excursion and spent 2 hours and 11 minutes as the first two men to walk on the moon. They stayed on the moon for a total of 21 hours and 36 minutes before blasting off for the journey back home to Earth.
Armstrong suddenly passed away nearly a year ago on August 25, 2012 at age 82 – read my stories, here and here.
Aldrin is still active and strenuously advocating for starting human expeditions to the Red Planet.
He outlined his exploration concepts in a newly published book titled – “Mission to Mars.”
The five F-1 engines used in the 138-foot-tall Saturn V first stage known as the S-IC generated 7.5 million pounds of liftoff thrust, or some 1.5 million pounds each. They stand 19 feet tall by 12 feet wide. Each one weighs over 18,000 pounds and was manufactured by Rocketdyne.
The F-1 had more power than all three space shuttle main engines combined. They burned a mixture of liquid oxygen and kerosene fuel for two-and-one-half-minutes, carrying the Saturn V to an altitude of some 36 miles.
Altogether, six Apollo Moon landing flights boosted by Saturn V’s sent a total of 12 humans on moon walking expeditions to Earth’s nearest neighbor during the 1960s and 1970s.
“This is a big milestone for the project and the whole team couldn’t be more excited to share it with you all,” Bezos wrote.
Bezos’ Blue Origin firm is also working to develop a commercial rocket and ‘space taxi’ to finally resume launching American astronauts back to low Earth orbit from American soil after a multi year gap.
More than four decades have passed since the last humans traversed the lunar surface in December 1972 during NASA’s Apollo 17 moon landing mission.
After all that time, the F-1 may yet live again.
NASA is now working on an upgraded F-1 to power a future variant of the new SLS heavy lift booster under development and intended to launch humans aboard the new Orion crew capsule back to the Moon and to deep space destinations including Asteroids and Mars.

When I looked out my south-facing window last night, I saw a gorgeous quarter Moon high in the sky. Giuseppe Petricca from Marina di Pisa, Tuscany, Italy took a longer look and created this beautiful composition of five different shots of the Moon on July 15, 2013, revealing how the appearance of the Moon changes as it sinks lower in the sky.
“These are the colours that our natural satellite assumes thanks to the Rayleigh Scattering in Earth’s atmosphere,” Guiseppe said via email. He noted that in his image, colors of the single shots are not digitally altered (except with a light Sharpness Mask to enhance the surface details.)
Guiseppe used a Nikon P90 bridge digital camera, at ISO 100, and used various but limited exposition times (trying to maintain a short medium exposition range in seconds, he said. His mosaic composed with Photoshop.

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory has arrived at the launch site on the Eastern Shore of Virginia at NASA’s Wallops Flight Facility on Wallops Island and is now in the midst of weeks of performance testing to ensure it is ready for liftoff in early September.
The LADEE lunar orbiting probe will be the first planetary science mission ever launched from NASAWallops and the Mid-Atlantic Regional Spaceport (MARS). It will soar to space atop a solid fueled Minotaur V rocket on its maiden flight.
LADEE will blaze a brilliant trail to the Moon during a spectacular nighttime blastoff slated for Sept. 6, 2013 at 11:27 PM from Launch Pad 0B.
LADEE is equipped with three science instruments to gather detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust.
“LADEE will investigate the moons tenuous exosphere, trace outgases like the sodium halo and lofted dust at the terminator,” said Jim Green, Planetary Science Division Director at NASA HQ, in an exclusive interview with Universe Today.
“The spacecraft has a mass spectrometer to identify the gases, a physical dust detector and an imager to look at scattered light from the dust. These processes also occur at asteroids.”
“And it will also test a laser communications system that is a technology demonstrator for future planetary science missions. It communicates at 650 megabits per second,” Green explained to me.
The couch sized 844 pound (383 kg) robotic 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 spacecraft was then shipped cross country by a dedicated truck inside a specially-designed shipping container – blanketed with protective nitrogen – which insulated the spacecraft from temperature, moisture, bumps in the road and more than a few crazy drivers.
The first leg of LADEE’s trip to the Moon took 5 days. The trans lunar leg will take 30 days.
It’s standard practice that whenever space probes are moved by ground transportation that they are accompanied by a caravan that includes a lead scout vehicle to ensure safe road conditions and followed by engineers monitoring the health and environmental storage conditions.
Technicians are now engaged in a lengthy series of performance tests to confirm that LADEE was not damaged during the road trip and that all spacecraft systems are functioning properly.
“One important preparation about to begin is spin-balancing LADEE,” says Butler Hine, LADEE Project Manager. “During this procedure, the spacecraft is mounted to a spin table and rotated at a high-speed to make sure it is perfectly balanced for launch.”
After all spacecraft systems pass the performance tests, LADEE will be fueled, encapsulated and moved to the Wallops Island launch pad later this summer for mating with the five stage Minotaur V booster stack.
“I’m excited about the night launch because people up and down the Atlantic seacoast will be able to see it,” Green told me.

NASA managers have announced a bold new plan to significantly alter and upgrade the goals and complexity of the 1st mission of the integrated Orion/Space Launch System (SLS) human exploration architecture – planned for blastoff in late 2017.
The ambitious first flight, called Exploration Mission 1 (EM-1), would be targeted to send an unpiloted Orion spacecraft to a point more than 40,000 miles (70,000 kilometers) beyond the Moon as a forerunner supporting NASA’s new Asteroid Redirect Initiative – recently approved by the Obama Administration.
The EM-1 flight will now serve as an elaborate harbinger to NASA’s likewise enhanced EM-2 mission, which would dispatch a crew of astronauts for up close investigation of a small Near Earth Asteroid relocated to the Moon’s vicinity.

Until recently NASA’s plan had been to launch the first crewed Orion atop the 2nd SLS rocket in 2021 to a high orbit around the moon on the EM-2 mission, said NASA Associate Administrator Lori Garver in an prior interview with me at the Kennedy Space Center.

The enhanced EM-1 flight would involve launching an unmanned Orion, fully integrated with the Block 1 SLS to a Deep Retrograde Orbit (DRO) near the moon, a stable orbit in the Earth-moon system where an asteroid could be moved to as early as 2021.
Orion’s mission duration would be nearly tripled to 25 days from the original 10 days.
“The EM-1 mission with include approximately nine days outbound, three to six days in deep retrograde orbit and nine days back,” Brandi Dean, NASA Johnson Space Center spokeswoman told Universe Today exclusively.
The proposed much more technologically difficult EM-1 mission would allow for an exceptionally more vigorous work out and evaluation of the design of all flight systems for both Orion and SLS before risking a flight with humans aboard.
Asteroid Capture in Progress
A slew of additional thruster firings would exercise the engines to change orbital parameters outbound, around the moon and inbound for reentry.
The current Deep Retrograde Orbit (DRO) plan includes several thruster firings from the Orion service module, including a powered lunar flyby, an insertion at DRO, an extraction maneuver from the DRO and a powered flyby on return to Earth.
Orion would be outfitted with sensors to collect a wide variety of measurements to evaluate its operation in the harsh space environment.
“EM-1 will have a compliment of both operational flight instrumentation and development flight instrumentation. This instrumentation suite gives us the ability to measure many attributes of system functionality and performance, including thermal, stress, displacement, acceleration, pressure and radiation,” Dean told me.
The EM-1 flight has many years of planning and development ahead and further revisions prior to the 2017 liftoff are likely.
“Final flight test objectives and the exact set of instrumentation required to meet those objectives is currently under development,” Dean explained.
Orion is NASA’s next generation manned space vehicle following the retirement of NASA’s trio of Space Shuttles in 2011.
The SLS launcher will be the most powerful and capable rocket ever built by humans – exceeding the liftoff thrust of the Apollo era Moon landing booster, the mighty Saturn V.
“We sent Apollo around the moon before we landed on it and tested the space shuttle’s landing performance before it ever returned from space.” said Dan Dumbacher, NASA’s deputy associate administrator for exploration systems development, in a statement.
“We’ve always planned for EM-1 to serve as the first test of SLS and Orion together and as a critical step in preparing for crewed flights. This change still gives us that opportunity and also gives us a chance to test operations planning ahead of our mission to a relocated asteroid.”
Both Orion and SLS are under active and accelerating development by NASA and its industrial partners.
The 1st Orion capsule is slated to blast off on the unpiloted EFT-1 test flight in September 2014 atop a Delta IV Heavy rocket on a two orbit test flight to an altitude of 3,600 miles above Earth’s surface.
Technicians work on mockups of the Orion crew capsule, Service Module and 6 ton Launch Abort System (LAS) to simulate critical assembly techniques inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center (KSC) in Florida for the EFT-1 mission due to liftoff in September 2014.

It will then reenter Earth’s atmosphere at speeds of about 20,000 MPH (11 km/sec) and endure temperatures of 4,000 degrees Fahrenheit in a critical test designed to evaluate the performance of Orion’s heatshield and numerous spacecraft systems.
Orion EFT-1 is already under construction at the Kennedy Space Center (KSC) by prime contractor Lockheed Martin – read my earlier story here.
Integration and stacking tests with Orion’s emergency Launch Abort System are also in progress at KSC – details here.
NASA says the SLS is also in the midst of a extensive review process called the Preliminary Design Review (PDR) to ensure that all launch vehicle components and systems will achieve the specified performance targets and be completed in time to meet the 2017 launch date. The PDR will be completed later this summer.
NASA’s goal with Orion/SLS is to send humans to the Moon and other Deep Space destinations like Asteroids and Mars for the first time in over forty years since the final manned lunar landing by Apollo 17 back in 1972.
NASA Headquarters will make a final decision on upgrading the EM-1 mission after extensive technical reviews this summer.
If you’re like me, you don’t change your computer’s desktop background nearly often enough… especially not considering all the fantastic space images that get released on an almost daily basis. But this picture, shared a couple of weeks ago by NASA’s Marshall Space Flight Center on their Flickr stream, really should inspire you to fix that. (I know it did for me!)
Captured by an Expedition 28 crew member aboard the International Space Station, this beautiful image shows a crescent-lit Moon seen through the upper layers of Earth’s atmosphere.
As it circles the globe, the ISS travels an equivalent distance to the Moon and back in about a day, making an excellent platform for viewing the Earth and its atmosphere. This photo shows the limb of Earth near the bottom transitioning into the orange-colored troposphere, the lowest and most dense portion of the Earth’s atmosphere. The troposphere ends abruptly at the tropopause, which appears in the image as the sharp boundary between the orange- and blue- colored atmosphere. Silvery-blue noctilucent clouds extend far above the Earth’s troposphere.
Expedition 28 began on May 23, 2011, with a crew consisting of Andrey Borisenko, Ron Garan, Alexander Samokutyaev, Sergei Volkov, Mike Fossum, and Satoshi Furukawa.
Look up into the night sky and count the moons. You can see only one moon, “the” Moon. But does the Earth have any other moons? Around the Solar System, multiple moons are the rule. Jupiter has 67 natural satellites, even Mars has two asteroid-like moons.
Could Earth have more than one?
Officially, the answer is no. The Earth has a single moon.
Today.
It’s possible Earth had more than one moon in the past, millions or even billions of years ago. Strange terrain on the far side of the Moon could be explained by a second moon crashing into it, depositing a layer of material tens of kilometers deep.
Moons could come and go over the billions of years of the Earth’s history.
For example, Mars has two Moons, but not for long. Phobos, the larger moon, is spiraling inward and expected to crash into the planet within the next 10 million years. And so, in the future, Mars will only have a single Moon, Deimos.
It’s also possible that the Earth might capture a Moon in the future. Neptune’s largest moon, Triton, orbits in the opposite direction from the rest of the moons around the planet. This suggests that Triton was actually a captured Kuiper Belt Object which strayed too close to the planet.
2006 RH120In fact, we did capture a 5-metre asteroid called 2006 RH120. It orbited the Earth four times during 2006/2007 before getting ejected again.
So we can assume events like this have happened in the past.
Additionally, we might have more moons, but they haven’t been discovered yet because they’re just too small. Researchers have calculated that there could be meter-sized asteroids in orbit around the Earth, remaining in orbit for hundreds of years before gravitational interactions push them out again.
And there are other objects that interact with Earth’s orbit in strange ways. Scientists don’t consider them moons, but they do stick around in our neighbourhood:
Asteroid 3753 Cruithne is in an orbital resonance with the Earth. It has a highly eccentric orbit, but takes exactly one year to orbit the Sun. From our perspective, it follows a slow, horse-shoe shaped path across the sky. Since the discovery of Cruithne in 1986, several other resonant near-Earth objects have been discovered.
2007 TK7There’s 2010 TK7, the Earth’s only known Trojan asteroid. It leads the Earth in the exact same orbit around the Sun, in a gravitationally stable point in space.
So, the answer… Earth only has a single Moon. Today. We might have had more moons in the past, and we might capture more in the future, but for right now… enjoy the one we’ve got.

I love those images taken from the International Space Station that show the Moon rising or setting above Earth’s limb, and when I first saw this image posted on Universe Today’s Flickr Group page, I thought someone had randomly posted one of those images taken by an astronaut on the ISS. But then I saw it was taken by Patrick Cullis, one of our “regulars” in our featured astrophotography posts.
This very beautiful, crisp and clear image was taken from a meteorological balloon at 86,000 feet (26,200 meters) above Earth, and it was no fluke that Patrick captured the Moon setting above Earth — it was planned.
“Once I knew the weather was going to work out for a launch I really planned out what time it needed to happen for the Moon to show up in the frame,” Patrick said via Flickr. “Definitely got lucky since the camera is just swinging around randomly under the balloon.”
He calls this image “Divided Moon,” as it shows the Continental Divide in Colorado. “I-70 can be seen snaking up from the bottom center towards Georgetown (valley stretching from left to right,) Loveland Pass, and the Eisenhower Tunnel,” Patrick explained. If you click on the image above (or go here to see it on Flickr) you can see other landmarks labeled.

While we recently posted a huge batch of images from the recent “Super Moon,” this new image from Sergio Garcia Rill in Houston is something special. It’s a composite photo of the Moonrise on June 22nd, and is a mosaic made from 37 separate images that show the Moon rising over the course of three hours, with the buildings of downtown Houston in the foreground.
“I stayed in place for over three hours,” Sergio explained on Flickr. “The hardest part was selecting which shots showed a sequential movement of the Moon, since I was altering shutter speeds between shots to compensate for changing light conditions.”
The full Moon of June 2013 was at perigee — or at its closest point in its orbit to Earth, and appeared up to 14% bigger and 30% brighter than other full Moons of 2013.

The full Moon of June 23, 2013 was the largest Moon of the year. This so-called “Super Moon” was at perigee — or at its closest point in its orbit to Earth, and was 14% bigger and 30% brighter than other full Moons of 2013.
But, if you looked up at the Moon last night and didn’t know about this, you may not have noticed! Some claims circulating on the internet tended to exaggerate how large the Moon would actually appear. However, that doesn’t mean the Moon wasn’t photogenic last night! The Moon is always a great target for photography or just gazing with your own eyes, and these images from Universe Today readers attest to the beauty of our closest companion in the night sky.
This lead image from Raven Yu from the Philippines shows the difference in size between last night’s perigee Moon and the apogee Moon (when it was farthest from Earth during its orbit) last November.

Three different pictures of the Moon from June 23, shared by Guiseppe Petricca from Italy, detailing not only the perigee Super Moon, but the ‘Moon Illusion” — of how the Moon looks bigger when it is close to the horizon.
“The middle one is the Moon at culmination in the local sky and the other two are taken as low as possible my local horizon permitted,” Guiseppe said via email. “Doing this, I managed to obtain two results: the first one is observing the different colours that due to the Rayleigh Scattering, ‘paint’ our satellite, when it’s low on its elevation. The second one is that, keeping a fixed magnification (24x – 110mm) one can easily debunk the optical illusion of the ‘bigger moon when it’s low on the horizon’. Since, if you observe carefully, the lower two ‘Moons’ are smaller than the higher one. However, the total personal experience is surely wonderful!! And the ‘horizon illusion’ makes you really think that the Moon is way bigger that the reality.”
