WALLOPS ISLAND, VA – A NASA moon probe named LADEE thundered to space tonight, Sept. 6, blazing a spectacular trail to orbit from a beachside launch pad in Virginia that was easily visible to tens of millions of spectators along the eastern seaboard as a result of crystal clear skies and the night time liftoff – see magnificent photo shot from NYC above by Ben Cooper/Launchphotography.com.

The drama at the LADEE launch site on the eastern shore of Virginia at NASA’s Wallops Island facility was palpable due to the historic and experimental nature of the mission.

Hordes of tourists flooded into Virginia to be eyewitnesses to an unprecedented space spectacle that marked Americas ‘Return to the Moon’ and a chance to see the type of big and exciting rocket launches previously reserved for Florida and California.

Everyone I spoke too was absolutely overwhelmed with the amazing beauty of the Minotaur V blastoff carrying LADEE to orbit, whooping and hollering, far beyond our wildest expectations as the crackling fire pierced through the night and reverberated in our ears!

“It was a picture perfect launch,” said NASA Associate Administrator John Grunsfeld at a post launch media briefing at NASA Wallops.

“LADEE will help us unravel the mysteries of the lunar atmosphere.”

Blastoff of NASA’s dust exploring Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory marked the first space probe of any kind ever launched beyond Earth orbit from NASA Wallops, as well as being the first planetary science mission from Wallops.

The Minotaur V rocket launched precisely on time at 11:27 p.m. EDT on the maiden flight of the powerful new Minotaur V rocket Launch Pad 0B on NASA’s Wallops Flight Facility.

“The spacecraft is healthy and power positive and separated from the fifth and last stage on time, approximately 23 minutes into the flight,” said Pete Worden to Universe Today after the liftoff. Worden is the Director of NASA’s Ames Research Center which designed and built LADEE using a revolutionary new design to reduce costs and increase science output.

The liftoff of LADEE (pronounced ‘laddie’ not ‘lady’) also marks the first launch of a five stage rocket and the first launch of a decommissioned Peacekeeper missile from Wallops. The Peacekeeper was a nuclear armed intercontinental ballistic missile ICBM built during the Cold War – now retired and refurbished by Orbital for peaceful uses.

The Minotaur V fifth stage boosted LADEE into a highly elliptical orbit. Over about the next 23 days, as LADEE orbits Earth 3.5 times, the Moon’s gravitational field will increase the apogee 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 that will require considerable fuel to maintain. The science mission duration is approximately 100 days.

The 844 pound (383 kg) robot explorer is the size of a couch and was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.

It is equipped with a trio of science instruments whose purpose 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.

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.

The couch sized 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 overall mission cost is approximately $280 million.

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

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

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 Sciences for peaceful uses.

The upper 5th stage is a new addition and what makes this Minotaur a new rocket class. The additional thrust is what converts the Minotaur V into an interplanetary booster that enables shooting for the Moon.

“I dreamed all my life about launching a rocket to the moon. And now we are doing it,” Lou Amorosi, told Universe Today at the Minotuar launch pad. Amorosi is the Senior Vice President of Orbital’s Small Space Launch Vehicle business.

“This mission further demonstrates the capabilities of our well-established Minotaur rocket family and our commitment to providing reliable access to space,” Amorosi noted in a post launch statement.

This Black Stain On Mars Could Be Volcanic Leftovers

At first glance, it looks like somebody dropped a huge paint can on Mars, spilling black stuff all over Becquerel crater. That dark material, however, is likely blown from another location on the Red Planet. It could even be volcanic eruption remnants, the European Space Agency says.

A set of stunning new images of the spot in the Arabia Terra region — which straddles the so-called “transition zone” between the north and south regions of the planet — reveal a combination of probable effects from wind, water and perhaps even the tilt of the axis of Mars. These pictures came courtesy of ESA’s Mars Express, which is orbiting the planet.

The crater — named after French physicist Antoine Henri Becquerel, a co-discoverer of radioactivity — is 103 miles (167 kilometers) in diameter and sinks 2.2 miles (3.5 km) below the rest of the area. This depression might have held water at some point.

“The mound rises about 1 km [0.62 miles] above the crater floor and comprises hundreds of layers of light-toned sediments, each just a few metres thick, made of sulphate-bearing rocks,” ESA stated. “On Earth, sulphates are most often formed via the evaporation of water, so the presence of these minerals in Becquerel crater suggests that water may once have pooled here in a vast crater lake, before evaporating away.”

The mystery of Mars’ missing water is one that is still puzzling scientists — NASA’s Spirit, Curiosity and Opportunity rovers all found rocks that likely formed in the presence of water, and several spacecraft have spotted features that appear to be similar to riverbeds or perhaps even oceans.

“One popular theory is that large changes in the tilt of the rotational axis of Mars leads to significant changes in its climate, reflected in the thickness and repeating patterns found in the layers of sediment,” ESA added. “A change in the environmental conditions would affect the way in which the sediments were initially deposited, as well as their subsequent resistance to erosion.”

Speaking of sediments, the image above shows the dark material extending far beyond the crater walls, a sign of powerful winds on the Red Planet. Now who’s tempted to go down there with a shovel to see what’s underneath?

As a point of trivia, another spot in Arabia Terra (Vernal Crater) was once considered a possible landing site for Mars Curiosity because scientists found evidence of ancient hot springs on the Red Planet. On Earth, these locations are usually filled with bacterial life.

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 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.

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.

“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!”

And remember that NASA has a 2nd historic launch from Wallops slated for Sep. 17 – with blastoff of the Orbital Sciences Antares rocket and Cygnus cargo carrier bound for its 1st flight to the International Space Station (ISS).

How Big is the Solar System?

For most of us, stuck here on Earth, we see very little of the rest of the Solar System. Just the bright Sun during the day, the Moon and the planets at night. But in fact, we’re embedded in a huge Solar System that extends across a vast amount of space.

Which begs the question, just how big is the Solar System?

Before we can give a sense of scale, let’s consider the units of measurement.

Distances in space are so vast, regular meters and kilometers don’t cut it. Astronomers use a much larger measurement, called the astronomical unit. This is the average distance from the Earth to the Sun, or approximately 150 million kilometers.

Mercury is only 0.39 astronomical units from the Sun, while Jupiter orbits at a distance of 5.5 astronomical units. And Pluto is way out there at 39.2 astronomical units.

That’s the equivalent of 5.9 billion kilometers.

If you could drive your car at highway speeds, from the Sun all the way out to Pluto, it would take you more than 6,000 years to complete the trip.

But here’s the really amazing part. Our Solar System extends much, much farther than where the planets are.

The furthest dwarf planet, Eris, orbits within just a fraction of the larger Solar System.

The Kuiper Belt, where we find a Pluto, Eris, Makemake and Haumea, extends from 30 astronomical units all the way out to 50 AU, or 7.5 billion kilometers.

And we’re just getting started.

In this new view, the heliopause is not a continuous shield that separates the solar domain from the interstellar medium, but a porous membrane with fingers and indentations.

Even further out, at about 80-200 AU is the termination shock. This is the point where the Sun’s solar wind, traveling outward at 400 kilometers per second collides with the interstellar medium – the background material of the galaxy. This material piles up into a comet-like tail that can extend 230 AU from the Sun.

But the true size of the Solar System is defined by the reach of its gravity; how far away an object can still be said to orbit the Sun.

In the furthest reaches of the Solar System is the Oort Cloud; a theorized cloud of icy objects that could orbit the Sun to a distance of 100,000 astronomical units, or 1.87 light-years away. Although we can’t see the Oort Cloud directly, the long-period comets that drop into the inner Solar System from time to time are thought to originate from this region.

The Sun’s gravity dominates local space out to a distance of about 2 light-years, or almost half the distance from the Sun to the nearest star: Proxima Centauri. Believe it or not, any object within this region would probably be orbiting the Sun, and be thought to be a part of the Solar System.

Back to our car analogy for a second. At those distances, it would take you 19 million years to complete the journey to the edge of the Solar System. Even NASA’s New Horizons spacecraft, the fastest object ever launched from Earth would need 37,000 years to make the trip.

So as you can see, our Solar System is a really really big place.

Are We Martians? Chemist’s New Claim Sparks Debate

Are Earthlings really Martians ?
Did life arise on Mars first and then journey on rocks to our planet and populate Earth billions of years ago? Earth and Mars are compared in size as they look today. NASA’s upcoming MAVEN Mars orbiter is aimed at answering key questions related to the habitability of Mars, its ancient atmosphere and where did all the water go.
Story updated[/caption]

Are Earthlings really Martians?

That’s the controversial theory proposed today (Aug. 29) by respected American chemist Professor Steven Benner during a presentation at the annual Goldschmidt Conference of geochemists being held in Florence, Italy. It’s based on new evidence uncovered by his research team and is sure to spark heated debate on the origin of life question.

Benner said the new scientific evidence “supports the long-debated theory that life on Earth may have started on Mars,” in a statement. Universe Today contacted Benner for further details and enlightenment.

“We have chemistry that (at least at the level of hypothesis) makes RNA prebiotically,” Benner told Universe Today. “AND IF you think that life began with RNA, THEN you place life’s origins on Mars.” Benner said he has experimental data as well.

First- How did ancient Mars life, if it ever even existed, reach Earth?

On rocks violently flung up from the Red Planet’s surface during mammoth collisions with asteroids or comets that then traveled millions of miles (kilometers) across interplanetary space to Earth – melting, heating and exploding violently before the remnants crashed into the solid or liquid surface.

An asteroid impacts ancient Mars and send rocks hurtling to space - some reach Earth — An asteroid impacts ancient Mars and send rocks hurtling to space – some reach Earth. Did they transport Mars life to Earth? Or minerals that could catalyze the origin of life on Earth?

“The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock,” says Benner, of The Westheimer Institute of Science and Technology in Florida. That theory is generally known as panspermia.

To date, about 120 Martian meteorites have been discovered on Earth.

And Benner explained that one needs to distinguish between habitability and the origin of life.

“The distinction is being made between habitability (where can life live) and origins (where might life have originated).”

NASA’s new Curiosity Mars rover was expressly dispatched to search for environmental conditions favorable to life and has already discovered a habitable zone on the Red Planet’s surface rocks barely half a year after touchdown inside Gale Crater.

Furthermore, NASA’s next Mars orbiter- named MAVEN – launches later this year and seeks to determine when Mars lost its atmosphere and water- key questions in the Origin of Life debate.

Of course the proposed chemistry leading to life is exceedingly complex and life has never been created from non-life in the lab.

The key new points here are that Benner believes the origin of life involves “deserts” and oxidized forms of the elements Boron (B) and Molybdenum (Mo), namely “borate and molybdate,” Benner told me.

“Life originated some 4 billion years ago ± 0.5 billon,” Benner stated.

He says that there are two paradoxes which make it difficult for scientists to understand how life could have started on Earth – involving organic tars and water.

Life as we know it is based on organic molecules, the chemistry of carbon and its compounds.

But just discovering the presence of organic compounds is not the equivalent of finding life. Nor is it sufficient for the creation of life.

And simply mixing organic compounds aimlessly in the lab and heating them leads to globs of useless tars, as every organic chemist and lab student knows.

Benner dubs that the ‘tar paradox’.

Although Curiosity has not yet discovered organic molecules on Mars, she is now speeding towards a towering 3 mile (5 km) high Martian mountain known as Mount Sharp.

Upon arrival sometime next spring or summer, scientists will target the state of the art robot to investigate the lower sedimentary layers of Mount Sharp in search of clues to habitability and preserved organics that could shed light on the origin of life question and the presence of borates and molybdates.

It’s clear that many different catalysts were required for the origin of life. How much and their identity is a big part of Benner’s research focus.

“Certain elements seem able to control the propensity of organic materials to turn into tar, particularly boron and molybdenum, so we believe that minerals containing both were fundamental to life first starting,” says Benner in a statement. “Analysis of a Martian meteorite recently showed that there was boron on Mars; we now believe that the oxidized form of molybdenum was there too.”

The second paradox relates to water. He says that there was too much water covering the early Earth’s surface, thereby causing a struggle for life to survive. Not exactly the conventional wisdom.

“Not only would this have prevented sufficient concentrations of boron forming – it’s currently only found in very dry places like Death Valley – but water is corrosive to RNA, which scientists believe was the first genetic molecule to appear. Although there was water on Mars, it covered much smaller areas than on early Earth.”

Parts of ancient Mars were covered by oceans, lakes and streams of liquid water in this artists concept, unlike the arid and bone dry Martian surface of today. Subsurface water ice is what remains of Martian water.

I asked Benner to add some context on the beneficial effects of deserts and oxidized boron and molybdenum.

“We have chemistry that (at least at the level of hypothesis) makes RNA prebiotically,” Benner explained to Universe Today.

“We require mineral species like borate (to capture organic species before they devolve to tar), molybdate (to arrange that material to give ribose), and deserts (to dry things out, to avoid the water problem).”

“Various geologists will not let us have these [borates and molybdates] on early Earth, but they will let us have them on Mars.”

“So IF you believe what the geologists are telling you about the structure of early Earth, AND you think that you need our chemistry to get RNA, AND IF you think that life began with RNA, THEN you place life’s origins on Mars,” Benner elaborated.

“The assembly of RNA building blocks is thermodynamically disfavored in water. We want a desert to get rid of the water intermittently.”

I asked Benner whether his lab has run experiments in support of his hypothesis and how much borate and molybdate are required.

“Yes, we have run many lab experiments. The borate is stoichiometric [meaning roughly equivalent to organics on a molar basis]; The molybdate is catalytic,” Benner responded.

“And borate has now been found in meteorites from Mars, that was reported about three months ago.

At his talk, Benner outlined some of the chemical reactions involved.

Although some scientists have invoked water, minerals and organics brought to ancient Earth by comets as a potential pathway to the origin of life, Benner thinks differently about the role of comets.

“Not comets, because comets do not have deserts, borate and molybdate,” Benner told Universe Today.

Benner has developed a logic tree outlining his proposal that life on Earth may have started on Mars.

“It explains how you get to the conclusion that life originated on Mars. As you can see from the tree, you can escape that conclusion by diverging from the logic path.”

Finally, Benner is not one who blindly accepts controversial proposals himself.

He was an early skeptic of the claims concerning arsenic based life announced a few years back at a NASA sponsored press conference, and also of the claims of Mars life discovered in the famous Mars meteorite known as ALH 84001.

“I am afraid that what we thought were fossils in ALH 84001 are not.”

The debate on whether Earthlings are really Martians will continue as science research progresses and until definitive proof is discovered and accepted by a consensus of the science community of Earthlings – whatever our origin.

On Nov. 18, NASA will launch its next mission to Mars – the MAVEN orbiter. Its aimed at studying the upper Martian atmosphere for the first time.

“MAVENS’s goal is determining the composition of the ancient Martian atmosphere and when it was lost, where did all the water go and how and when was it lost,” said Bruce Jakosky to Universe Today at a MAVEN conference at the University of Colorado- Boulder. Jakosky, of CU-Boulder, is the MAVEN Principal Investigator.

MAVEN will shed light on the habitability of Mars billions of years ago and provide insight on the origin of life questions and chemistry raised by Benner and others.

Curiosity Spies a Martian Annular Eclipse

It’s always interesting to consider the astronomical goings-on that occur under alien skies.

On August 17^th, Curiosity wowed us once again, catching the above sequence of images of the Martian moon Phobos transiting the Sun.

Such phenomena have been captured by the Curiosity, Opportunity and Spirit rovers before, as the twin Martian moons of Deimos & Phobos cross the face of the Sun. But these recent images taken by Curiosity’s right Mastcam pair are some of the sharpest yet.

Orbiting only an average of 6,000 kilometres above the surface of Mars, Phobos is the closest to its primary of any moon in the solar system. It appears about 11 arc minutes in size when directly overhead, about 3 times smaller than our own Moon does from the Earth.

“This event occurred near noon at Curiosity’s location, which put Phobos at its closest point to the rover, appearing larger against the Sun than it would at other times of the day,” Said co-investigator Mark Lemmon of Texas A&M University in a recent press release. “This is the closest to a total eclipse that you can have on Mars.”

Phobos is 40% more distant from an observer standing on the surface of Mars when it is rising above the local horizon than when it is overhead. The Sun is about 20’ arc minutes across as seen from Mars, 66% of its diameter as seen from the Earth.

The sequence above spans only six seconds in duration. You would easily note the apparent motion of Phobos as it drifted by! Also, since Phobos orbits Mars once every 7.7 hours, it actually rises in the west and sets in the east. The Martian day is over three times this span, at 24.6 hours long. Deimos has a more sedate orbit of 30.4 hours in duration.

The twin Moons of Deimos and Phobos were discovered this month back during the opposition of 1877 by Asaph Hall using the United States Naval Observatory’s newly installed 65 centimetre refractor. The moons are just within the grasp of eagle-eyed amateurs near opposition. You’ve got another opportunity to cross these elusive moons off of your life list coming up in the Spring of 2014.

It’s especially captivating that you can make out the irregular “potato shape” of Phobos in the above images. With low orbital inclinations relative to the equator of Mars of 1.1 degrees for Phobos and 0.9 degrees for Deimos, solar transits are not an uncommon occurrence, transpiring somewhere along the Martian surface with every orbit. If Phobos were twice as close to Mars, it would completely cover the Sun in a total solar eclipse. What Curiosity gave us this month is more akin to an annular eclipse with a ragged central shadow. An annular eclipse occurs when the occulting body is too distant to cover the Sun, leaving a bright, shining ring, or annulus.

On the Earth, we live in an epoch where annular eclipses are slightly more common than total solar eclipses, as the Moon currently recedes from us to the tune of 3.8 centimetres a year. About 1.4 billion years from now, the last total solar eclipse will be seen from the Earth. The next purely annular eclipse as seen from Earth occurs on April 29^th, 2014 across Australia and the Antarctic.

Conversely, Phobos is in a “death spiral,” meaning that it will one day crash into Mars about 30-50 million years from now. This also means that in about half that time, it will also be large enough to visually cover the Sun when crossing it near local noon. For a brief time far in the future, jagged total solar eclipses will be visible from Mars. That is, if the gravitational field of Mars doesn’t rip Phobos apart before that!

But beyond just aesthetics, these observations serve a scientific purpose as well. These phenomena serve to refine our understanding of the precise positions of Phobos and Deimos and their orbits.

“This one is by far the most detailed image of any Martian lunar transit ever taken, and it is especially useful because it is annular. It was taken closer to the Sun’s center than predicted, so we learned something.”

The track during the August 17^th observation was off by about 2-3 kilometres, allowing for a surprise central transit of the Sun as seen from Curiosity’s location.

Both Phobos and Deimos are captured asteroids only 22.2 & 12.6 kilometres across, respectively. Both must be subject to occasional bombardment from meteorites blasted off of the surface of nearby Mars. Sample return missions to Phobos have been proposed. Russia’s ill-fated Phobos-Grunt mission would’ve done just that.

Will humans ever stand on the surface of the Red Planet and witness an annular eclipse of the Sun by Phobos in person? Well, if we make it there by November 10^th, 2084, observers placed on the slopes of Elysium Mons will witness just such an event… with a rare transit of Earth and the Moon to boot!:

Arthur C. Clarke wrote of a transit of Earth from Mars that occurred in 1984 in his science fiction short story Transit of Earth.

Hey, I’m marking my calendar for the 2084 event… assuming, of course, my android body is ready by then!

Titan Has a Fancy Collar

UV image of Titan acquired by Cassini on April 13 (NASA/JPL-Caltech/SSI)

As high summer slowly but steadily approaches on Saturn, Cassini is opening a window to the seasonal changes that occur not only on the ringed planet but also its moons. Here we can see a dark band developing around Titan’s north polar latitudes, a “fancy collar” made visible in ultraviolet wavelengths.

Polar collars have previously been seen by both Hubble and Voyager 2, and in fact a southern version was observed by HST 5 years after the planet’s 1995 equinox.

This summer collar is thought to be part of a seasonal process, related to the migration of upper-level haze material within Titan’s atmosphere.

An Illustrative Explanation Of Our Solar System

The Solar System: Our Home in Space (screenshot) © Philipp Dettmer Information Design

The Solar System: it’s our home in space, the neighborhood that we all grew up in and where — unless we figure out a way to get somewhere else — all of our kids and grandkids and great-great-great-great-times-infinity-great-grandkids will grow up too. That is, of course, until the Sun swells up and roasts Earth and all the other inner planets to a dry crunchy crisp before going into a multi-billion year retirement as a white dwarf.

But until then it’s a pretty nice place to call home, if I may say so myself.

Edu-film designer Philipp Dettmer and his team have put together a wonderful little animation explaining the basic structure of the Solar System using bright, colorful graphics and simple shapes to illustrate the key points of our cosmic neighborhood. It won’t teach you everything you’ll ever need to know about the planets and it’s not advisable to use it as a navigation guide, but it is fun to watch and well-constructed, with nice animation by Stephan Rether and narration by Steve Taylor.

Check out the full video below:

“Through information design, concepts can be made easy and accessible when presented in a short, understandable edu-film or perhaps an infographic. Whether explaining the vastness of the universe or the tiniest building blocks of life – all information can be presented in a way that everyone understands. Regardless of prior knowledge.”

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

LADEE Minotaur V Launch – Maximum Elevation Map

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!
