WALLOPS ISLAND, VA – An unprecedented spectacle is set to light up the skies this Friday night, Sept. 6, courtesy of NASA when America returns to the Moon with the history making nighttime launch of the LADEE lunar orbiter atop a retired and specially converted intercontinental ballistic missile (ICBM) from NASA’s Wallops Island facility on the Virginia shoreline.

Blastoff of NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory atop the maiden flight of the powerful new Minotaur V rocket is slated for 11:27 p.m. EDT Sept. 6 from Launch Pad 0B along the Eastern Shore of Virginia at NASA Wallops.

Because it’s at night and lifting off from the most densely populated region of the United States, the flames spewing from the tail of Minotaur could be visible to tens of millions of distant spectators – weather permitting – who have never before witnessed such a rocket launch.

So you don’t have to be watching locally to join in the fun and excitement. And you can always watch the NASA TV webcast online on a smartphone or laptop.

The LADEE (pronounced ‘laddie’ not ‘lady’) launch is historic in many ways.

No space satellite has ever been launched to beyond Earth orbit from NASA’s Wallops’s launch base in Virginia, it’s the first flight to the Moon from Wallops, the first Minotaur V rocket launch based on the Peacekeeper missile, and it’s the first flight of the revolutionary new modular spacecraft design aimed at significantly cutting the cost of exploring space.

So although the very best views are available from local areas in Virginia, Maryland and Delaware just tens of miles away from the Wallops Island launch pad, magnificent viewing opportunities are available from a broad region up and down the East Coast and into the interior.

Let’s look at some viewing maps courtesy of Orbital Sciences, the company responsible for assembling the Minotaur V and integrating it with the LADEE spacecraft – built by NASA’s Ames Research Center.

First up is the Maximum elevation map showing how high the rocket will be visible in degrees from the heavily populated US East Coast stretching from Maine to both Carolinas and into the industrial Midwest.

Herein are a series of graphics showing the Minotaur V trajectory and what you should see – during firings of the first three stages – from the perspective of standing on the ground or skyscrapers at a variety of popular destinations including the US Capitol, Lincoln Memorial, Kitty Hawk, NC, Atlantic City, NJ, New York City, Cape Cod and more.

The five stage Minotaur V rocket stands 80.6 feet (24.6 meters) tall, is 7.6 feet (2.3 m) in diameter and weighs 197,034 pounds (89,373 kilograms.

The first three stages of the Minotaur V are based on the nuclear armed Peacekeeper ICBM intercontinental ballistic missile built during the Cold War – now retired and refurbished by Orbital for peaceful uses. It’s literally beating swords into plowshares.

The 5th stage is a new addition and what makes this Minotaur a new rocket class. The added thrust is precisely what enables shooting for the Moon.

For anyone coming to the Wallops area for an eyewitness view of the launch, NASA worked with local officials to establish several viewing locations just 10 miles or so from the launch pad at the Mid-Atlantic Regional Spaceport, at NASA’s Wallops Flight Facility, Wallops Island, Va.

Visitors to the area may view the launch from Robert Reed Park on Chincoteague or Beach Road spanning the area between Chincoteague and Assateague Islands.

Both sites will feature a live countdown and broadcast and NASA personnel will be on hand to discuss the LADEE launch and goals of the mission.

A big-screen projector will broadcast live in Robert Reed Park beginning at 9:30 p.m.

“We’re excited about this partnership with the community in providing an enhanced launch experience to members of the public,” said Jeremy Eggers, public information officer for NASA Wallops in a statement. “The live countdown and launch broadcast will place people in mission control on launch night for what is already a historic mission for Wallops and the Eastern Shore.”

NASA TV starts a live broadcast of the launch at 9:30 p.m. on Sept 6 – available here: http://www.nasa.gov/ntv

The couch sized 844 pound (383 kg) robotic explorer is equipped with 3 science instruments and a laser technology demonstrator.

These include an ultraviolet and visible light spectrometer that will gather detailed information about the composition of the tenuous lunar atmosphere; a neutral mass spectrometer to measure variations in the lunar atmosphere over time; a laser dust experiment that will collect and analyze dust particle samples; and a laser communications experiment that will test the use of lasers in place of radio waves for high speed data communications with Earth.

Historic Sept. 6 Virginia Moon Shot Heralds Revolutionary New Paradigm for Fundamental Science Query- NASA Director Interview

In an exclusive new interview with Universe Today, NASA’s Ames Research Center Director Pete Worden was “very excited” to discuss the historic Moon Shot set to launch NASA’s LADEE lunar orbiter from the Virginia coast and the NASA Wallops Island facility on Friday night, Sept. 6, that boasts “a new modular design” that can revolutionize how we explore our solar system “with robotic orbiters, landers and rovers” – and is aimed at “answering fundamental science questions.”

“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Worden told Universe Today. NASA Ames leads the LADEE mission. “It will study the pristine moon to study significant questions.”

“And it will demonstrate a new modular approach that will give us science at a lower cost. We are very excited.”

“It will tell us a lot about the moon,” Worden told me.

When America returns to the Moon with the LADEE spacecraft blasting off shortly before midnight Sept. 6, it could potentially be watched by many tens of millions of spectators – weather permitting – along the US East Coast stretching from Maine to the Carolina’s and into parts of the Midwest. See launch visibility map below.

And the science timing for LADEE’s lunar mission is just perfect as well since several countries and corporations are gearing up to dispatch a batch of new orbiters and landers to Earth’s nearest neighbor that could change its character forever.

“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”

The purpose of LADEE’s trio of science instruments is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface.

Engineers from NASA's Ames Research Center have successfully completed launch preparation activities for blastoff of NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) observatory on Sept. 6.

The couch sized probe is built on a ‘modular common spacecraft bus’, or body, that could be implemented on space probes to explore a wide variety of targets in the solar system.

“We think the modular bus is a winner,” Worden explained to Universe Today.

“LADEE could lead to other low cost missions to orbit and even land on the Moon, near Earth asteroids, Mercury and also the moons of Mars.”

“The LADEE bus is a strong contender for future NASA planetary missions, especially landers on bodies with a tenuous atmosphere. And small micro-rovers are possible too. We are really proud of it!”

LADEE is NASA’s first ever planetary mission to launch from the Eastern Shore of Virginia at NASA’s Wallops Flight Facility on Wallops Island. The blastoff is expected to draw large crowds. Some local hotels are already sold out.

The Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory is NASA’s next mission to the Moon.

It thunder’s to space at 11:27 p.m. Friday, Sept. 6, from launch complex 0B at NASA’s Wallops Island facility and the Mid-Atlantic Regional Spaceport (MARS) atop the maiden flight of the new, solid fueled Minotaur V rocket developed by Orbital Sciences Corp.

The goal of the $280 Million mission is to gain a thorough understanding of long-standing unknowns about the tenuous atmosphere, dust and surface interactions that will help scientists understand other planetary bodies as well.

“After Apollo, the amazing thing is that we opened as many questions as we answered,” said Worden. “One of the key issues is – What is the environment on the Moon’s surface from the lunar day to the lunar night?”

“And what are the limitations that would place on our activities there?”

“Although the moon has a tenuous atmosphere it’s actually very active and interacts very strongly with the solar wind. It may produce something that on Earth we would call a ‘dust storm’.”

“We also wish to have the ‘ground truth’ [measurements] of the Moon’s environment before humans change things.”

And change is inexorably coming to the Moon rather soon.

“The Chinese plan to land on the Moon by year’s end,” Worden elaborated.

“What we found during Apollo is that an artificial disturbance very considerably changes the Moon’s atmosphere – or exosphere.”

“So we really want to known the pristine state of the lunar exosphere before its changed by human activity.”

“The data we have from Apollo surface measurements shows that it took many months for the lunar exosphere to go back to its pristine state.”

“Now there are probably a half dozen to a dozen programs planning to land on the Moon in the next decade. So we may never see the Moon’s pristine state again!”

“So these are pretty significant questions that we will have an opportunity to answer with LADEE.”

LADEE is the first spacecraft of any kind that’s been designed, developed, built, integrated and tested at NASA’s Ames Research Center in Moffett Field, Calif.

“This is our first complete mission built out at Ames,” Worden explained.

“It’s also the first of a new paradigm where we are trying to develop a low cost modular bus design.

The approach on LADEE was to make it a mix and match modular bus – rather than a singular modular bus.

“So we have modular slices that use a propulsion stage, lander stage, communications stage, science payload stage, bus housekeeping stage and more,” Worden told me.

“In the past many others tried to build a ‘one size fits all’ modular bus. But it turns out that one size does NOT fit all needs.”

“So we took a page from how you build desktop computers.”

“We put in different modules that you can expand or subtract much more easily without changing the whole fundamental architecture or design.”

“So assuming this works well, I think you will see a lot more missions. And that makes it really exciting as our first mission.”

And the Ames modular bus has definitely sparked entrepreneurial interest.

“The bus is already an approach being used by at least one of the Google Lunar X-Prize competitors! The Moon Express team has looked at it a lot to transition that capability to them,” Worden explained.

How about future NASA missions?

“The LADEE bus is also a key part of several of our Ames proposals for future planetary missions,” Worden replied.

“The original design concept about seven years ago was for a small lunar lander. The lander propulsion would likely be a solid fueled stage.”

“Ultimately, NASA decided to go with the orbiter instead. And that showed the strength of the modular bus design – that it was very easy to change it from a lunar lander to the LADEE mission orbiter studying the lunar exosphere.”

I asked if it could deploy a small rover too?

“Yes- a small, micro rover is possible, perhaps 10 to 20 inches in size. And you could pack a lot of science on the small rover using today’s technology!

Thus there are numerous exploration possibilities – all dependent on the Federal budget for NASA in this extremely difficult fiscal environment.

NASA Ames had “built parts and spacecraft components and science instruments before, but not a spacecraft in the entirety and in house,” Worden told Universe Today.

For example, a few years back Ames built the LCROSS lunar impacting spacecraft that smashed into the Moon’s south pole and discovered a treasure trove of water ice.

LCROSS piggybacked as a secondary science mission payload onto NASA’ s Lunar Reconnaisannce Orbiter (LRO) when the duo launched from Cape Canaveral, Florida atop an Atlas V rocket.

NASA Ames has now taken the next step – having designed and built the whole LADEE spacecraft from beginning to end.

“This is our first real baby. It’s very exciting,” beamed Worden.

“LADEE is a pretty phenomenal mission.”

They say “Virginia is for Lovers’

Well coming this Friday, “Virginia is for Space Lovers too!”

Evidence of Internal Moon Water Found

The central peak of Bullialdus crater (Credit: NASA/GSFC/Arizona State University)

Scientists have detected magmatic water — water that originates from deep within the Moon’s interior — on the surface of the Moon. These findings represent the first such remote detection of this type of lunar water, and were arrived at using data from NASA’s Moon Mineralogy Mapper (M3) carried aboard India’s Chandrayaan-1 lunar orbiter.

The discovery represents an exciting contribution to the rapidly changing understanding of lunar water according to Rachel Klima, a planetary geologist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., and lead author of the paper, “Remote detection of magmatic water in Bullialdus Crater on the Moon” published in the August 25 issue of the journal Nature Geoscience.

Chandrayaan-1, India’s first mission to the Moon, entered lunar orbit on Nov. 8, 2008

“For many years, researchers believed that the rocks from the Moon were ‘bone dry’ and that any water detected in the Apollo samples had to be contamination from Earth,” said Klima, a member of the NASA Lunar Science Institute’s (NLSI) Scientific and Exploration Potential of the Lunar Poles team. “About five years ago, new laboratory techniques used to investigate lunar samples revealed that the interior of the Moon is not as dry as we previously thought. Around the same time, data from orbital spacecraft detected water on the lunar surface, which is thought to be a thin layer formed from solar wind hitting the lunar surface.”

“This surficial water unfortunately did not give us any information about the magmatic water that exists deeper within the lunar crust and mantle, but we were able to identify the rock types in and around Bullialdus crater,” said co-author Justin Hagerty, of the U.S. Geological Survey. “Such studies can help us understand how the surficial water originated and where it might exist in the lunar mantle.”

LRO image of the 60-km Bullialdus crater (NASA/GSFC/Arizona State University)

M3 (pronounced “M-cube”) fully imaged the large impact crater Bullialdus in 2009. “It’s within 25 degrees latitude of the equator and so not in a favorable location for the solar wind to produce significant surface water,” Klima explained. “The rocks in the central peak of the crater are of a type called norite that usually crystallizes when magma ascends but gets trapped underground instead of erupting at the surface as lava. Bullialdus crater is not the only location where this rock type is found, but the exposure of these rocks combined with a generally low regional water abundance enabled us to quantify the amount of internal water in these rocks.”

See detailed reports of M3 data regarding hydroxyls in Bullialdus crater from NASA’s Lunar Planetary Institute (LPI) here.

After examining the M3 data, Klima and her colleagues found that the crater has significantly more hydroxyl — a molecule consisting of one oxygen atom and one hydrogen atom — compared to its surroundings. “The hydroxyl absorption features were consistent with hydroxyl bound to magmatic minerals that were excavated from depth by the impact that formed Bullialdus crater,” Klima writes.

The internal magmatic water provides information about the Moon’s volcanic processes and internal composition, Klima said. “Understanding this internal composition helps us address questions about how the Moon formed, and how magmatic processes changed as it cooled. There have been some measurements of internal water in lunar samples, but until now this form of native lunar water has not been detected from orbit.”

“This impressive research confirms earlier lab analyses of Apollo samples, and will help broaden our understanding of how this water originated and where it might exist in the lunar mantle.”

The Cyber-Myth That Just Won’t Die: See Mars as Large as a Full Moon!!!

We've been here before... (All article images and bad photoshopping courtesy of the author).

It’s hard to believe that it’s been with us for a decade now.

Ten years ago this week, the planet Mars reached made an exceptionally close pass of the planet Earth. This occurred on August 27^th, 2003, when Mars was only 56 million kilometres from our fair planet and shined at magnitude -2.9.

Such an event is known as opposition. This occurs when a planet with an orbit exterior to our own reaches a point opposite to the Sun in the sky, and rises as the Sun sets. In the case of Mars, this occurs about every 2.13 years.

But another myth arose in 2003, one that now makes its return every August, whether Mars does or not.You’ve no doubt gotten the chain mail from a well-meaning friend/relative/coworker back in the bygone days a decade ago, back before the advent social media when spam was still sorta hip. “Mars to appear as large as the Full Moon!!!” it breathlessly exclaimed. “A once in a lifetime event!!!”

Though a little over the top, the original version did at least explain (towards the end) that Mars would indeed look glorious on the night of August 27^th, 2003 … through a telescope.

Mars during the historic opposition season of '03. — Mars during the historic opposition season of ’03.

But never let facts get in the way of a good internet rumor. Though Mars didn’t reach opposition again until November 7^th 2005, the “Mars Hoax” email soon began to make its rounds every August.

Co-workers and friends continued to hit send. Spam folder filled up. Science news bloggers debunked, and later recycled posts on the silliness of it all.

Now, a decade later, the Mars Hoax seems to have successfully made the transition over to social media and found new life on Facebook.

Mars as seen during a close conjunction with the Moon on July 17th, 2003. Mars was 20 arc seconds in size at the time leading up to the August 2003 opposition. — How Mars really appears next to the Moon: Mars as seen during a close conjunction with the Moon on July 17th, 2003. Mars was 20 arc seconds in size at the time, leading up to the August 2003 opposition. Image courtesy of Rick Stankiewicz, used with permission.

No one knows where the Mars Hoax meme goes to weather the lean months, only to return complete with all caps and even more exclamation points each and every August. Is it the just a product of the never ending quest for the almighty SEO? Are we now destined to recycle and relive astronomical events in cyber-land annually, even if they’re imaginary?

Perhaps, if anything there’s a social psychology study somewhere in there, begging the question of why such a meme as the Mars Hoax endures… Will it attain a mythos akin to the many variations of a “Blue Moon,” decades from now, with historians debating where the cultural thread came from?

Here are the facts:

-Mars reaches opposition about every 2.13 Earth years.

-Due to its eccentric orbit, Mars can vary from about 56 million to over 101 million kilometres from the Earth during oppositions.

-Therefore, Mars can appear visually from 13.8” to 25.1” arc seconds in size.

-But that’s still tiny, as the Moon appears about 30’ across as seen from the Earth. You could ring the local horizon with about 720 Full Moons end-to-end, and place 71 “maxed out Mars’s” with room to spare across each one of them!

-And although the Full Moon looks huge, you can cover it up with a dime held at arm’s length…. Try it sometime, and amaze your email sending/Facebook sharing friends!

–Important: Mars NEVER gets large enough to look like anything other than a star-like point to the naked eye.

Reality check... how Mars really appears compared to the Moon as seen during a close conjunction in 2012. — Reality check… how Mars actually appears compared to the Moon as seen during a close conjunction in 2012.

-And finally, and this is the point that should be getting placed in all caps on Facebook, to the tune of thousands of likes… MARS ISN’T EVEN ANYWHERE NEAR OPPOSITION in August 2013!!! Mars is currently low in the dawn sky in the constellation Cancer on the other side of the Sun. Mars won’t be reaching opposition until April 8th, 2014, when it will reach magnitude -1.4 and an apparent size of 15.2” across.

Still, like zombies from the grave, this myth just won’t die. In the public’s eye, Mars now shines “As big as” (or bigger, depending on the bad hyperbole used) as Full Moon now every August. Friends and relatives hit send, (or these days, “share” or “retweet”) observatories and planetariums get queries, astronomers shake their heads, and science bloggers dust off their debunking posts for another round. Hey, at least it’s not 2012, and we don’t have to keep remembering how many “baktuns are in a piktun…”

What’s a well meaning purveyor & promoter science to do?

Feed those hungry brains a dose of reality.

There are real things, fascinating things about Mars afoot. We’re exploring the Red Planet via Mars Curiosity, an SUV-sized, nuclear powered rover equipped with a laser. The opposition coming up next year means that the once every 2+ year launch window to journey to Mars is soon opening. This time around, the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission and, just perhaps, India’s pioneering Mars Orbiter Mission may make the trip. Launching from Cape Canaveral on November 18th, MAVEN seeks to answer the questions of what the climate and characteristics of Mars were like in the past by probing its tenuous modern day atmosphere.

The circumstances for opositions of Mars from — The circumstances for the oppositions of Mars from 2001 to 2029.

And as opposition approaches in 2014, Mars will again present a fine target for small telescopes. As a matter of fact, Mars will pass two intriguing celestial objects next month, passing in front of the Beehive cluster and — perhaps — a brightening Comet ISON. More to come on that later this week!

And it’s worth noting that after a series of bad oppositions in 2010 and 2012, oppositions in 2014 and 2016 are trending towards more favorable. In fact, the Mars opposition of July 27^th, 2018 will be nearly as good as the 2003 approach, with Mars appearing 24.1” across. Not nearly as “large as a Full Moon” by a long shot, but hey, a great star party target.

Will the Mars Hoax email enjoy a resurgence on Facebook, Twitter or whatever is in vogue then? Stay tuned!

NASA’s LADEE Lunar Probe Set for Spectacular Science and September Night Launch – Visible to Millions and Millions

A spectacular nighttime blastoff blazing a historic trail to the Moon is set to soar in two weeks time when NASA’s LADEE spacecraft lifts off from the Eastern Shore of Virginia at NASA’s Wallops Flight Facility on Wallops Island – from America’s newest spaceport.

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory will thunder to space at 11:27 p.m. Friday, Sept. 6, from the commercial Mid-Atlantic Regional Spaceport (MARS) launch complex 0B at NASA’s Wallops Island facility atop the maiden flight of the new, solid fueled Minotaur V rocket developed by Orbital Sciences Corp.

LADEE’s late night launch will be absolutely spectacular and visible to tens of millions of spectators up and down the US East coast and interior areas stretching into the Midwest- weather permitting.

“I love this mission,” said John Grunsfeld, NASA Associate Administrator for Science at NASA Headquarters, at a media briefing today, Aug. 22.

“With NASA’s prior LRO and GRAIL spacecraft we studied the Moon’s surface and interior. Now with LADEE we study the atmosphere and dust,” said John Grunsfeld.

The purpose of LADEE is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface. In turn this will lead to a better understanding of other planetary bodies in our solar system and beyond.

The small car sized LADEE lunar orbiter mission will be historic in many ways. It’s the first probe of any kind ever launched to beyond Earth orbit from NASA Wallops, as well as being the first planetary science mission from Wallops.

It also marks the first launch of a five stage rocket and the first launch of a decommissioned Peacekeeper missile from Wallops.

The 5th stage is a new addition and what makes this Minotaur a new rocket class. The added thrust is precisely what enables shooting for the Moon.

Recently, I had an exclusive tour and photoshoot up close and personal with the upper stages of LADEE’s Minotaur V rocket at Wallops prior to integration at the commercial launch pad – 0B – and will be reporting on that here and in upcoming stories.

“LADEE is equipped with three science instruments to study the atmosphere and dust and a lunar laser technology demonstration,” said Joan Salute, LADEE program executive, NASA Headquarters.

“The lunar atmosphere is so thin that the molecules never collide,’ said Sarah Noble, LADEE program scientist, NASA Headquarters.

“It’s a ‘Surface Boundary Exosphere’ which is actually the most common type of atmosphere in our Solar System.”

Scientists also hope to solve a mystery dating back nearly five decades to the Apollo moon landing era, by determining if electrically charged lunar dust is responsible for the pre-sunrise horizon glow seen by the Apollo astronauts and also by the unmanned Surveyor 7 lander, according to Noble.

“This is the first NASA mission with a dedicated laser communications experiment,” said Don Cornwell, mission manager for the Lunar Laser Communications Demonstration, NASA’s Goddard Space Flight Center, Greenbelt, Md.
I asked when we could see laser communications implemented on future NASA spacecraft?

“A new laser communications system could possibly be used on the 2020 Mars rover from the surface of Mars,” Grunsfeld told Universe Today.

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 is a first of its kind vehicle built from a NASA Ames-developed Modular Common Spacecraft Bus architecture that can be applied to other missions. The mission cost is approximately $280 million.

The Minotaur V will boost LADEE into a highly elliptical orbit. Then over the next 23 days, as LADEE orbits Earth 3.5 times, the Moon’s gravitational field will increase the perigee of its orbit. The spacecraft will fire its on-board braking thrusters to achieve lunar orbit.

The mission will fly in a very low science orbit of about 50 kilometers altitude above the moon. The science mission duration is approximately 100 days.

“It’s limited by the amount of onboard fuel required to maintain orbit,” Doug Voss, launch manager, Wallops, told Universe Today.

“I’m excited about the night launch because people up and down the Atlantic seacoast will be able to see it,” Jim Green, Planetary Science Division Director at NASA HQ, told me.

And don’t forget that NASA has a 2nd really big launch from Wallops slated for Sep. 17 – with blastoff of the Orbital Sciences Antares rocket and Cygnus cargo carrier on their historic 1st mission to the International Space Station (ISS).

I’ll be on site at Wallops for both historic launches on Sep. 6 and 17 – reporting for Universe Today.

We’ll see you in Virginia!

On July 19, millions of Earthlings worldwide participated in NASA’s ‘Wave at Saturn’ campaign as the NASA Cassini Saturn orbiter turned about and imaged all of us.

Earthlings from 40 countries and 30 U.S. states heeded NASA’s call to photograph themselves while smiling and waving at Saturn and Cassini across 1 billion miles of interplanetary space and shared over 1400 images.

The results of all those images has now been assembled into a fabulous collage in the shape of our planet and released today (Aug. 21) by NASA and the Cassini team as a tribute to the People of Earth.

“Did you wave at Saturn and send us your photo? Then here’s looking at you!” NASA announced on the Cassini Facebook page.

This event was the first time that the citizens of Earth knew in advance that a distant interplanetary spacecraft was photographing portraits of our home planet and our Moon. NASA invited everyone to participate.

Photos flooded into NASA via Twitter, Facebook, Flickr, Instagram, Google+ and email.

“Thanks to all of you, near and far, old and young, who joined the Cassini mission in marking the first time inhabitants of Earth had advance notice that our picture was being taken from interplanetary distances,” said Linda Spilker, Cassini project scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif, in a statement.

“While Earth is too small in the images Cassini obtained to distinguish any individual human beings, the mission has put together this collage so that we can celebrate all your waving hands, uplifted paws, smiling faces and artwork.”

The Cassini imaging science team is still assembling the hundreds of images of Saturn and Earth snapped by the spacecraft as we were waving, to create individual color composites and a panoramic view of the ‘pale blue dot’ and the entire Saturnian system.

To capture all of Saturn and its wide swath of rings, Cassini’s wide angle camera snapped a mosaic of 33 footprints on July 19, 2013.

“At each footprint, images were taken in different spectral filters for a total of 323 images,” says Carolyn Porco, Cassini Imaging Team leader, Space Science Institute in Boulder, Colo.

Cassini took the pictures of Earth from a distance of about 898 million miles (1.44 billion kilometers) away from the home to every human being that has ever lived.

Here is our partial version of Cassini’s mosaic.

Cassini was launched from Florida in 1997.

It achieved orbit at Saturn in 2004 and has transmitted breathtaking images and science that revolutionized our understanding of the Saturnian system.

The mission is scheduled to continue until 2017 when it will commit a suicide death dive into the humongous gas giant.

Coincidentally, the first humans (Neil Armstrong and Buzz Aldrin) set foot on the Moon 44 years ago nearly to the day of Cassini’s Earth-Moon portrait on July 20, 1969 aboard Apollo 11.

And likewise on July 19, 2013, billionaire space enthusiast Jeff Bezos announced that his dive teams had recovered components of an Apollo 11 first stage F-1 rocket engine from the Saturn V moon rocket that propelled the first humans to the Moon.

Venus And Moon Caught In A Crazy, Phase-y Coincidence Tonight

Venus reflected in Boulder Lake north of Duluth, Minn. two nights ago. Credit: Bob King

Curious coincidences occur in the sky just as they do on Earth. Take tonight for instance. The moon is in gibbous phase or about 3/4 full – 78% to be exact – while Venus, which also undergoes phases identical to the moon, is likewise gibbous and 78% full.

That’s just cool. If you have telescope, focus on Venus low in the western sky just after sunset and see a perfect replica in miniature of tonight’s moon.

Look for the cloudy but beautiful planet about a fist up in the west-southwest shortly after sunset. Stellarium — *Look for Venus about a fist up in the west-southwest shortly after sunset. Stellarium*

Be sure you’re out early as the planet is low to begin with and drops lower in the west with each passing minute. Provided the sky is haze-free, Venus isn’t difficult to spot even 5 minutes after sunset. Look about 10 degrees (one fist held at arm’s length) above the west-southwest horizon.

The moon and Venus are coincidentally in exactly the same phase tonight - 78% gibbous. Stellarium — *The moon and Venus are coincidentally in exactly the same phase tonight – 78% gibbous. Stellarium*

The moon shows spectacular craters and mountains, but Venus hides its equally spectacular scenery of volcanic mountains, craters and cracked plains beneath a permanent cover of sulfur-dioxide-laced clouds. Clouds are excellent reflectors of sunlight. Not only is the planet brilliant because of them but looks as white as a shiny cue ball.

Venus' changing position with relation to the Earth as it orbits around the sun causes it to exhibit phases like the moon. I've marked approximately where Venus is in mid-August. After gibbous, the planet will wane to half and then a crescent over the coming months as it catches up and passes the Earth.

Tomorrow night the moon and Venus will go their own phase-y way, the moon fattening up toward full and Venus slowly slimming its waistline as it works its way toward the Earth. For now enjoy their temporary bond.

NAVAL STATION NORFOLK,VA – When American astronauts again venture into deep space sometime in the next decade, their return trip to Mother Earth will end with the splashdown of their Orion capsule in the Pacific Ocean – much like the Apollo lunar landing crews of four decades ago.

But before that can happen, Orion must first pass through a myriad of milestones to insure the safe return of our human crews.

A NASA and U.S. Navy test successfully demonstrated the water recovery of the Orion crew module today (Aug. 15) at Naval Station Norfolk in Virginia – and Universe Today witnessed the entire operation.

“Today’s test was terrific,” Scott Wilson, NASA’s Orion Manager of Production Operations, told Universe Today in a post test interview at Naval Station Norfolk.

“We got all the data we needed and the test was very successful. This was exactly what we wanted to do and we don’t like surprises.”

Today’s ‘Orion Stationary Recovery Test’ was conducted to support the upcoming first flight of Orion on the EFT-1 mission due to blastoff in September 2014 from Cape Canaveral, Florida.

“We completed all of our primary and secondary test objectives,” Wilson stated.

Teams of US Navy divers in a flotilla of amphibious boats launched from the USS Arlington approached a test version of the Orion capsule known as the boilerplate test article (BTA). The Arlington was docked against its pier during the test in a benign, controlled environment.

Divers attached several tow lines to the capsule, in a coordinated operation with the Arlington, and led the capsule into the ship’s flooded well deck.

The Orion capsule was carefully towed inside the well deck and positioned over the recovery cradle. The sea water was drained and the capsule was attached to the recovery cradle.

“During the test there is constant radio communications between the ship and the divers teams in the boats.”

“The operation within the well deck areas are also being controlled as well as the rope and winch handlers on the boat,” Wilson told me.

At the conclusion of the test, myself and the NASA social media participants boarded the USS Arlington and toured the Orion capsule for a thrilling up close look.

“Today marks a significant milestone in the Navy’s partnership with NASA and the Orion Human Space Flight Program,” said Navy Commander Brett Moyes, Future Plans Branch chief, U.S. Fleet in a statement.

“The Navy is excited to support NASA’s continuing mission of space exploration. Our unique capabilities make us an ideal partner for NASA in the recovery of astronauts in the 21st century — just as we did nearly a half century ago in support of America’s quest to put a man on the moon.”

The ocean recovery of Orion will be far different from the Apollo era where the crew’s were first hoisted out of the floating capsule and the capsule then hoisted on deck of a US Navy aircraft carrier.

The next Orion water recovery test will be conducted in the open waters of the Pacific Ocean in January 2014.

NASA’s Langley Research Center in nearby Hampton, VA is conducting an extensive drop test program in support of the Orion project.

“The Orion capsule tested today has the same mold line and dimensions as the Orion EFT-1 capsule.”

“The Orion hardware and the Delta IV Heavy booster for the EFT-1 launch are on target for launch in 2014,” Wilson told me.

Watch this NASA Video of the Orion test:

During the unmanned Orion EFT-1 mission, the capsule will fly on a two orbit test flight to an altitude of 3,600 miles above Earth’s surface, farther than any human spacecraft has gone in 40 years.

The EFT-1 mission will provide engineers with critical data about Orion’s heat shield, flight systems and capabilities to validate designs of the spacecraft before it begins carrying humans to new destinations in the solar system, including an asteroid and Mars.

It will return to Earth at a speed of approximately 20,000 mph for a splashdown in the Pacific Ocean.

Right now its T Minus 1 Year and counting to liftoff of Orion EFT-1.

A Challenging Series of Occultations of Spica by the Moon Coming to a Sky Near You

An occultation of the star Mu Geminorum (to the upper right off the dark limb of the Moon) Photo by author.

The first in a cycle of challenging occultations of the bright star Spica for northern hemisphere observers begins this coming Monday on August 12^th.

Watching a bright star or planet wink out on the dark limb of the Moon can be an amazing event to witness. It’s an abrupt “now you see it, now you don’t” event in a universe which often seems to move at an otherwise glacial pace. And if the event grazes the limb of the Moon, an observer may see a series of winks as the starlight streams through the lunar valleys.

Close companion stars have been discovered during occultations, and astronomers even used a series of occultations of radio source 3C 273 in 1962 to pin down the position of the first quasar.

An occultation occurs when one object passes in front of another as seen from the observer’s vantage point. The term has its hoary roots back in a time when astronomy was intertwined with its pseudoscience ancestor of astrology. Even today, I still get funny looks from non-astronomy friends when I use the term occultation, as if it just confirms their suspicions of the arcane arts that astronomers really practice in secret.

But back to reality-based science. At an apparent magnitude of +1.1, Spica is the 3rd brightest star that the Moon can occult along its five degree path above and below the plane of the ecliptic. It’s also one of only four stars brighter than +1.4 magnitude on the Moon’s path. The others are Antares (magnitude +1.0), Regulus (magnitude +1.4), and Aldebaran (magnitude +0.8). All of these are bright enough to be visible on the lunar limb through binoculars or a telescope in the daytime if conditions are favorable.

It’s interesting to note that this situation also changes over time due to the precession of the equinoxes. For example, the bright star Pollux was last occulted by the Moon in 117 BC, but cannot be covered by the Moon in our current epoch.

Spica is currently in the midst of a cycle of 21 occultations by our Moon. This cycle started in July 25^th, 2012 and will end in January 2014.

Spica is a B1 III-IV type star 10 times the mass of the Sun. At 260 light years distant, Spica is one of the closest candidates to the Earth along with Betelgeuse to go supernova. Now, THAT would make for an interesting occultation! Both are safely out of the ~100 light year distant “kill zone”.

What follows are the circumstances for the next four occultations of Spica by the Moon. The times are given for closest geocentric conjunction of the two objects. Actual times of disappearance and reappearance will vary depending on the observer’s location. Links are provided for each event which include more info.

Looking westward 30 minutes after sunset for North American viewers on the night of August 12th. (Created by the Author using Starry Night).

First up is the August 12^th occultation of Spica, which favors Central Asia and the Asian Far East. This will occur late in the afternoon sky around 09:00 UT and prior to sunset. The waxing crescent Moon will be six days past New phase. North American observers will see the Moon paired five degrees from Spica with Saturn to the upper left on the evening of August 12^th.

Next is the September 8^th daytime occultation of Spica for Europe, the Middle East and northern Africa around ~15UT. This will be a challenge, as the Moon will be a waxing crescent at only 3 days past New. Observers in the Middle East will have the best shot at this event, as the occultation occurs at dusk and before moonset. Note that the Moon also occults Venus six hours later for Argentina and Chile.

Looking to the east the morning of November 2nd for North American observers. (Created by the author using Stellarium).

After taking a break in October (the occultation of October 5 occurs only 23 hours after New and is unobservable), the Moon again occults Spica on November 2^nd for observers across Europe & Central Asia. This will be a difficult one, as the Moon will be only 20 hours from New and a hybrid solar eclipse that will cross the Atlantic and central Africa. It may be possible to lock on to the Moon and track it up into the daylight, just be sure to physically block the rising Sun behind a building or hill!

USNO — The occultation footprint of Spica by the Moon for November 29th, 2013. (Reproduced from the Astronomical Almanac online and produced by the U.S. Naval Observatory and H.M. Nautical Almanac Office).

Finally, the Moon will occult Spica for North American observers on November 29^th centered on 17:03 UT. This will place the event low in the nighttime sky for Alaskan observers. It’ll be a bit more of a challenge for Canadian and U.S. observers in the lower 48, as the Moon & Spica will be sandwiched between the Sun and the western horizon in the mid-day sky. As an added treat, comet C/2012 S1 ISON will reach perihelion on November 28th, just 20 hours prior and will be reaching peak brilliance very near the Sun.

And as an added bonus, the Moon will be occulting the +2.8 star Alpha Librae (Zubenelgenubi) on August 13^th for central South America.

All of these events are challenges, to be sure. Viewers worldwide will still catch a close night time pairing of the Moon and Spica on each pass. We’ve watched the daytime Moon occult Aldebaran with binoculars while stationed in Alaska back in the late 1990’s, and can attest that such a feat of visual athletics is indeed possible.

And speaking of which, the next bright star due for a series of occultations by the Moon is Aldebaran starting in 2015. After 2014, Spica won’t be occulted by the Moon again until 2024.

But wait, there’s more- the total eclipse of the Moon occurring on April 15^th 2014 occurs just 1.5 degrees from Spica, favoring North America. This is the next good lunar eclipse for North American observers, and one of the best “Moon-star-eclipse” conjunctions for this century. Hey, at least it’ll give U.S. observers something besides Tax Day to look forward to in mid-April. More to come in 2014!
