WALLOPS ISLAND, VA – “All Systems Are GO” for the Sept. 18 launch of Orbital Sciences Antares commercial rocket carrying the first ever fully functional Cygnus commercial resupply vehicle to orbit on the history making first flight blasting off from NASA’s Wallops Island Facility– along the eastern shore of Virginia and bound for the International Space Station (ISS).

Here’s our guide on “How to See the Antares/Cygnus Launch” – complete with viewing maps and trajectory graphics from a variety of prime viewing locations courtesy of Orbital Sciences, the private company that developed both the Antares rocket and Cygnus spaceship aimed at keeping the ISS fully operational for science research.

And although the launch is slated for late morning it should still be visible to millions of spectators along a lengthy swath of the US East Coast from North Carolina to Connecticut – weather permitting – who may have never before witnessed such a mighty rocket launch.

The daylight liftoff of the powerful two stage Antares rocket is scheduled for Wednesday, Sept 18 at 10:50 a.m. EDT from Launch Pad 0A at the Mid-Atlantic Regional Spaceport at NASA Wallops Island, Virginia. The launch window extends 15 minutes to 11:05 a.m.

Up top is the view as anticipated from “The Top of the Rock” or Rockefeller Center in New York City. See below the extraordinary image of LADEE’s launch from “Top of the Rock” by Ben Cooper to compare the day and night time sighting delights.

In anticipation of liftoff, the Antares rocket was rolled out to Pad 0A on Friday morning Sept. 13 and I was on hand for the entire event – see my rollout photos here and upcoming.

The Antares launch follows closely on the heels of the spectacularly bright Sept. 6 nighttime Moon shot blastoff of the Minotaur V rocket that successfully injected NASA’s LADEE lunar orbiter into its translunar trajectory.

And just as was the case with the Minotaur V and LADEE, you don’t have to be watching locally to join in and experience all the fun and excitement. As with any NASA launch, you can also follow along with up to the minute play by play by watching the NASA TV webcast online or on smartphones, iPods or laptops.

It’s hard to say exactly how long and how bright the rockets flames and exhaust trail will be visible since it depends on the constantly changing lighting, prevailing clouds and overall weather conditions.

But one thing is for sure. If you don’t go outside and watch you’re giving up a great opportunity.

And keep in mind that Antares will be moving significantly slower than the Minotaur V.

Herein are a series of graphics showing the Antares trajectory and what you should see during firings of both stages from the perspective of standing on the ground or skyscrapers at a variety of popular destinations including Annapolis, the US Capitol, Lincoln Memorial, National Air and Space Museum, Atlantic City, NJ, New York City and more.

The goal of the mission is to demonstrate the safe and successful launch, rendezvous and docking of the privately developed Cygnus cargo carrier with the International Space Station (ISS) and delivery of 1300 pounds of essential supplies, food, clothing, spare parts and science gear to the six person resident human crews – currently Expedition 37.

Although it’s the 2nd launch of Antares following the maiden flight in April, this is the first flight of the Cygnus commercial delivery system. The demonstration and testing will be the same as what SpaceX accomplished in 2012 with their competing Falcon 9/Dragon architecture.

The mission is designated Orb-D1 and is funded with seed money by NASA’s COTS program to replace the cargo delivery duties of NASA’s now retired Space Shuttle orbiters.

For those who are traveling to witness the launch locally in the Chincoteague, Va., area, there will be two public viewing sites said Jeremy Eggers, NASA Wallops Public Affairs Officer in an interview with Universe Today.

“There will be are two local sites open to the public,” Eggers told me. “Folks can watch at either the NASA Wallops Flight facility Visitors Center (http://sites.wff.nasa.gov/wvc) or the beach at Assateague National Seashore (http://www.nps.gov/asis/index.htm).”

“There will be loudspeakers to follow the progress of the countdown, but no TV screens as done with the LADEE launch.”

So far the weather outlook is promising with a 75% chance of “GO” with favorable conditions at launch time.

NASA Television coverage of the Antares launch will begin at 10:15 a.m. on Sept 18 – (www.nasa.gov/ntv).

Be sure to watch for my continuing Antares and LADEE mission reports from on site at NASA’s Wallops Launch Pads in sunny Virginia – reporting for Universe Today.

Story updated – see close up mosaic views of Darwin outcrop below[/caption]

NASA’s Curiosity Mars rover has just rolled into an intriguing site called ‘Darwin’ at ‘Waypoint 1’- having quickly picked up the driving pace since embarking at last on her epic trek to mysterious Mount Sharp more than two months ago. Did life giving water once flow here on the Red Planet?

Because the long journey to Mount Sharp – the robots primary destination – was certain to last nearly a year, the science team carefully choose a few stopping points for study along the way to help characterize the local terrain. And Curiosity has just pulled into the first of these so called ‘Waypoints’ on Sept 12 (Sol 392), the lead scientist confirmed to Universe Today.

“Curiosity has arrived at Waypoint 1,” project scientist John Grotzinger, of the California Institute of Technology in Pasadena, told Universe Today.

“Darwin is named after a geologic formation of rocks from Antarctica.”

She has now driven nearly 20% of the way towards the base of the giant layered Martian mountain she will eventually scale in search of life’s ingredients.

Altogether, the team selected five ‘Waypoints’ to investigate for a few days each as Curiosity travels in a southwestward direction on the road from the first major science destination in the ‘Glenelg’ area to the foothills of Mount Sharp, says Grotzinger.

“We’ll stay just a couple of sols at Waypoint 1 and then we hit the road again,” Grotzinger told me.

‘Waypoint 1’ is an area of intriguing outcrops that was chosen based on high resolution orbital imagery taken by NASA’s Mars Reconnaissance Orbiter (MRO) circling some 200 miles overhead. See route map herein.

In fact the team is rather excited about ‘Waypoint 1’ that’s dominated by the tantalizing rocky outcrop discovered there nicknamed ‘Darwin’.

Although Curiosity will only stay a short time at each of the stops, the measurements collected at each ‘Waypoint’ will provide essential clues to the overall geologic and environmental history of the six wheeled rover’s touchdown zone.

“Waypoint 1 was chosen to help break up the drive,” Grotzinger explained to Universe Today.

“It’s a chance to study outcrops along the way.”

The images from MRO are invaluable in aiding the rover handlers planning activities, selecting Curiosity’s driving route and targeting of the most fruitful science forays during the long trek to Mount Sharp – besides being absolutely crucial for the selection of Gale Crater as the robots landing site in August 2012.

The ‘Darwin’ outcrop may provide more data on the flow of liquid water across the crater floor.

For at least a couple of days, the science team of NASA's Mars rover Curiosity is focused on a full-bore science campaign at a tantalizing, rocky site informally called "Darwin."

The scientists goal is to compare the floor of Gale Crater to the sedimentary layers of 3 mile high (5 kilometer high) Mount Sharp.

Waypoint 1 is just over 1 mile along the approximately 5.3-mile (8.6-kilometer) route from ‘Glenelg’ to the entry point at the base of Mount Sharp.

Curiosity spent over six months investigating the ‘Yellowknife Bay’ area inside Glenelg before departing on July 4, 2013.

What’s the origin of Darwin’s name?

“Darwin comes from a list of 100 names the team put together to designate rocks in the Mawson Quadrangle – Mawson is the name of a geologist who studied Antarctic geology,” Grotzinger told me.

“Recently we left the Yellowknife Quadrangle, so instead of naming rocks after geological formations in Canada’s north, we now turn to formation names of rocks from Antarctica, and Darwin is one of them.

“That will be the theme until we cross into the next quad,” Grotzinger explained.

Inside Yellowknife Bay, Curiosity conducted the historic first interplanetary drilling into Red Planet rocks and subsequent sample analysis with her duo of state of the art chemistry labs – SAM and CheMin.

At Yellowknife Bay, the 1 ton robot discovered a habitable environment containing the chemical ingredients that could sustain Martian microbes- thereby already accomplishing the primary goal of NASA’s flagship mission to Mars.

“We want to know how the rocks at Yellowknife Bay are related to what we’ll see at Mount Sharp,” Grotzinger elaborated in a NASA statement. “That’s what we intend to get from the waypoints between them. We’ll use them to stitch together a timeline — which layers are older, which are younger.”

On Sept. 5, Curiosity set a new one-day distance driving record for the longest drive yet by advancing 464 feet (141.5 meters) on her 13th month on the Red Planet.

As Curiosity neared Waypoint 1 she stopped at a rise called ‘Panorama Point’ on Sept. 7, spotted an outcrop of light toned streaks informally dubbed ‘Darwin and used her MastCam telephoto camera to collect high resolution imagery.

Curiosity will use her cameras, spectrometers and robotic arm for contact science and a “full bore science campaign” involving in-depth mineral and chemical composition analysis of Darwin and Waypoint 1 for the next few Sols, or Martian days, before resuming the trek to Mount Sharp that dominates the center of Gale Crater.

She will not conduct any drilling here or at the other waypoints, several team members have told me, unless there is some truly remarkable ‘Mars-shattering’ discovery.

Why is Curiosity now able to drive longer than ever before?

“We have put some new software – called autonav, or autonomous navigation – on the vehicle right after the conjunction period back in March 2013,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today.

“This will increase our ability to drive. But how much it helps really depends on the terrain.”

And so far the terrain has cooperated.

“We are on a general heading of southwest to Mount Sharp,” said Erickson. See the NASA JPL route map.

“We have been going through various options of different planned routes.”

As of today (Sol 394), Curiosity remains healthy, has traveled 2.9 kilometers and snapped over 82,000 images.

If all goes well Curiosity could reach the entry point to Mount Sharp sometime during Spring 2014, at her current driving pace.

Where’s the Best Place To Drill for History on Mars?

The process of selecting a site for NASA's next landing on Mars, planned for September 2016, has narrowed to four semifinalist sites located close together in the Elysium Planitia region of Mars. The mission known by the acronym InSight will study the Red Planet's interior, rather than surface features, to advance understanding of the processes that formed and shaped the rocky planets of the inner solar system, including Earth. Image credit: NASA/JPL-Caltech

Where’s the best place to drill baby, drill on Mars – and not for oil but digging into Mars’ past? Apparently, a relatively level spot near the equator is the preferred spot. The 2016 InSight lander is the next mission to land on Mars and it will use a probe to hammer down 3-5 meters under the surface. NASA has now narrowed down the potential landing sites to just four from an original twenty-two proposed locations, and all four lie along the planet’s mid-section on the plains of Elysium Planitia.

“We picked four sites that look safest,” said geologist Matt Golombek from the Jet Propulsion Laboratory. Golombek is leading the site-selection process for InSight. “They have mostly smooth terrain, few rocks and very little slope.”

This artist's concept depicts the stationary NASA Mars lander known by the acronym InSight at work studying the interior of Mars.

InSight stands for “Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport” and it is scheduled to launch in March 2016 and land in September of that year. The mission will investigate processes that formed and shaped Mars and will help scientists better understand the evolution of our inner solar system’s rocky planets, including Earth. It will also monitor the planet’s current internal temperature and any seismology taking place.

So, unlike previous Mars landings, what is on the surface in the area matters little in the choice of a site except for safety considerations.

“This mission’s science goals are not related to any specific location on Mars because we’re studying the planet as a whole, down to its core,” said Bruce Banerdt, InSight principal investigator. “Mission safety and survival are what drive our criteria for a landing site.”

Elysium works well for the InSight mission because of two basic engineering constraints. One requirement is being close enough to the equator for the lander’s solar array to have adequate power at all times of the year. Also, the elevation must be low enough to have sufficient atmosphere above the site for a safe landing. The spacecraft will use the atmosphere for deceleration during descent.

InSight also needs penetrable ground for its probe that will monitor heat coming from the planet’s interior. This tool can penetrate through broken-up surface material or soil, but could be foiled by solid bedrock or large rocks. InSight also will deploy a seismometer on the surface and will use its radio for scientific measurements.

Images from the Mars Reconnaissance orbiter have been crucial in narrowing down the sites, and will continue to aid scientists and engineers in choosing the final site.

Golombek said that since considering what is below the surface is important to evaluate candidate landing sites, scientists also studied MRO images of large rocks near Martian craters formed by asteroid impacts. Impacts excavate rocks from the subsurface, so by looking in the area surrounding craters, the scientists could tell if the subsurface would have probe-blocking rocks lurking beneath the soil surface.

Each semifinalist site is an ellipse measuring 81 miles (130 kilometers) from east to west and 17 miles (27 kilometers) from north to south. Engineers calculate the spacecraft will have a 99-percent chance of landing within that ellipse, if targeted for the center.
The team will select two or three finalists by the end of 2014, and make a final decision on InSight’s destination by the end of 2015.

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

The revolutionary modular science probe is equipped with a Lunar Laser Communication Demonstration (LLCD) that will attempt to show two-way laser communication beyond Earth is possible, expanding the possibility of transmitting huge amounts of data.

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!”

Ready, Set, Observe! How to See Comet ISON In The Early Morning Sky

OK, you’ve waited patiently for Comet ISON to brighten and reappear in the dawn sky. It has. Now you’re chomping at the bit for a look at it in your telescope. Before you set the alarm and venture into the night, let’s prepare for what to expect. The better you know your target, the easier it will be to find.

The latest brightness estimates from the amateur comet community place ISON around magnitude 13, bright enough to be within reach of 10-inch (25 cm) and larger telescopes. Alan Hale of Arizona, co-discover of Comet Hale-Bopp, was one of the first to see it. Through his 16-inch (41 cm) reflecting telescope on September 1, he noted the comet as a small object about 0.6 arc minutes across (1 arc minute = 1/30 the diameter of the full moon), brighter in the center and shining faintly at magnitude 13.1. Picture a small, dim patch of glowing mist and you’ve got the picture. Hale’s observing conditions were excellent though he did have to contend with light from the nearby crescent moon. Starting tomorrow morning, the moon will finally be out of the picture.

This map shows the sky as you face east tomorrow morning Sept. 3 around 5 a.m. local time just before the start of morning twilight. The comet is not far from Mars and the Beehive Cluster. Stellarium — With the moon out of the sky, now is a great time to hunt for Comet ISON. This map shows the sky as you face east tomorrow morning Sept. 3 around 5 a.m. local time just before the start of morning twilight. The comet is near both Mars and the Beehive Cluster. Stellarium

A sharp-eyed observer under the best skies would expect to see a fuzzy object this faint in a telescope as small as 8-inches (20 cm). Most of us will need something a little bigger. A 10-12 incher (25-30 cm) should do the trick until the comet swells into the 11-12 magnitude range. But you’ll need more than a hefty scope. Key to spotting ISON are good charts, a steady atmosphere for sharp images (shaky air blurs faint objects into invisibility) and catching the comet at the right time. I also encourage you to use averted vision, a great technique for spotting faint sky objects. Instead of staring directly at the comet, look off to the side of its position. That way you allow the comet’s feeble photons to flood your eye’s rod cells, those most sensitive to dim light.

This tighter view shows the comet in relation to the naked eye star Gamma Cancri and the lovely Beehive Cluster in Cancer the Crab. Stellarium — *This tighter view shows the comet (on Sept. 3) in relation to the naked eye star Gamma Cancri and the pretty Beehive Cluster in Cancer the Crab. North is up, west to the right. Stellarium*

While it now rises around 3-3:30 a.m. local time, you’ll get your best – or only – view once ISON has cleared the light-sucking thick air and haze so common near the horizon. The optimum viewing time occurs shortly before the start of morning twilight when the comet will be about 15 degrees high in the northeastern sky. At mid-northern latitudes,where twilight begins about 1.5 hours before sunrise, that’s around 5 a.m. Did I mention you’d lose a few hours sleep in your pursuit?

Lucky for us comet hunters, ISON’s location is easy to find only a few degrees east of the 1st magnitude planet Mars and about 2 degrees north of the familiar Beehive Cluster or M44. The first map shows the general view to get you oriented. The second takes us in closer to show the comet’s relation to the Beehive Cluster, and the third provides a detailed telescopic view with stars plotted to about 12th magnitude. The comet positions on the detailed map are plotted for 5 a.m. CDT. Since ISON moves relatively slowly, those positions will be accurate for a time zone or two either way. If you live significantly farther east or west of the U.S. Central Time Zone, you can interpolate between the tick marks.

It’s good news for skywatchers from here on out as ISON continues to brighten and rise higher in the east with each passing night. A month from now, it should be visible in scopes as small as 6-inches (15 cm). Good luck in your comet quest!

How to See Mars in September 2013: The Red Planet Pierces the Beehive & More

Mars on September 8th. (Created by the author using Stellarium).

Launch season for Mars missions is almost upon us once again.

This is a time when spacecraft can achieve an optimal trajectory to reach the Red Planet, expending a minimal amount of fuel and taking the shortest period of time. This window of opportunity, which opens once every two years, always opens up about six months prior to Martian opposition.

For you stargazers, this is also the best time to observe the Red Planet as it makes its closest approach to Earth. And no, it won’t appear as large as a Full Moon, but it will make for a fine telescopic target.

During the last launch window in 2011-12, Mars Curiosity made the journey, and Russia’s Phobos-Grunt tried. Hey, it’s a tough business, this spaceflight thing. This time around, The Indian Space Research Organization (ISRO) hopes to launch its first ever interplanetary spacecraft, with its Mars Orbiter Mission departing on October 18th. NASA is also sending its Mars Atmosphere Volatile EvolutioN mission known as MAVEN to study the atmosphere of the Red Planet.

Opposition next occurs on April 8th, 2014, but the start of launch season always finds Mars emerging high to the east at dawn. Starting next week, Mars has some interesting encounters that are worth checking out as a prelude to the upcoming opposition season.

The planet Mars shines at +1.6 magnitude and is about 4” in size in September. This is a far cry from its maximum size of 15.1” that it will achieve next spring, and its grandest maximum size of 25.1” that it reached in 2003. All oppositions of Mars are not created equal, because of the planet’s 9.3% eccentric orbit.

But the good news is, we’re trending towards a better series of oppositions, which follow a roughly 15 year cycle. In 2018, we’ll see an opposition nearly as good as the 2003 one, with Mars appearing 24.1” in size. This is also the time frame that Dennis Tito wants to launch his crewed Mars 2018 flyby.

But back to the present. The action starts on September 2^nd when the waning crescent Moon passes 6.1 degrees SSW of Mars.

Mars is currently in the constellation Cancer, and will actually transit (pass in front of) the open star cluster known as the Beehive or Messier 44, standing only 0.23 degrees from its center on September 8^th. M44 is 1.5 degrees in size, and this presents an outstanding photo-op.

At high power, you might just be able to catch the real time motion of Mars against the background stars of M44. Mars currently rises three hours before the Sun, giving you a slim window to accomplish this feat.

Mars is also in the midst of a series of transits of the Beehive Cluster, with one occurring every other year. Mars last crossed M44 on October 1^st, 2011. The next time you’ll be able to spy this same alignment won’t be until August 20^th, 2015.

But another cosmic interloper may photo-bomb Mars in September.

We’re talking about none other than Comet C/2012 S1 ISON, the big wildcard event of the season. Comet ISON is just peeking out from behind the Sun now, and dedicated amateurs have already managed to recover it. “IF” it follows projected light curve predictions, ISON may reach binocular visibility of greater than +10^th magnitude by October 1st and may breech naked eye visibility by early November.

ISON approaches within two degrees of Mars on September 27^th. Its closest apparent approach is will be on Oct 18th at a minimum separation of 0.89 degrees, just over the size of a Full Moon. How bright ISON will actually be at that point is the question of the season. To quote veteran comet hunter David Levy, “Comets are like cats. They have tails, and they do whatever they want.” The closest physical approach of Mars and Comet ISON is on October 1st at 0.07 astronomical units, or 10.4 million kilometres apart. Both will be crossing over from the astronomical constellations of Cancer into Leo in late September.

Mars gets another close shave from a comet next year, when Comet C/2013 A1 Siding Spring passes 123,000 kilometres from Mars on October 19^th, 2014. Interestingly, MAVEN will be arriving just a month prior to this if it departs Earth at the start of its 21 day window. Engineers have noted that an increase in cometary dust may be a concern for the newly arrived spacecraft during insertion into Martian orbit.

MAVEN Principal Investigator Bruce Jakosky notes that the first concern is the safety of the spacecraft, the second is studies of Mars, and the third is, just perhaps, to carry out observations of the comet.

Look for more information on Universe Today about the Martian cometary flybys as each event gets closer.

September is a great time to begin observations of the Red Planet. Usually, 8” seconds in diameter is the threshold that is frequently quoted for the first surface features (usually to polar ice caps) to become apparent, but we’re already seeing astro-imagers getting detailed images of Mars, right now.

Be sure to follow Mars on its trek across the September dawn skies as robotic explorers prepare to embark on their epic journeys!

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.

Curiosity accomplished Historic 1st drilling into Martian rock at John Klein outcrop on Feb 8, 2013 (Sol 182) and discovered a habitable zone, shown in this context mosaic view of the Yellowknife Bay basin taken on Jan. 26 (Sol 169).

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 Conducts Science on the Go and Zooms to Stunning Mount Sharp

Curiosity Spies Mount Sharp – her primary destination. Curiosity will ascend mysterious Mount Sharp and investigate the sedimentary layers searching for clues to the history and habitability of the Red Planet over billions of years. But first she must safely trespass through the treacherous dark dunes fields. This mosaic was assembled from over 2 dozen Mastcam camera images taken on Sol 352 (Aug 2, 2013).

See the full mosaic below [/caption]

It’s never a dull moment for NASA’s Curiosity rover at T Plus 1 Year since touchdown on the Red Planet and T Minus 1 year to arriving at her primary target, the huge mountain overwhelming the center of the landing site inside Gale Crater.

Curiosity is literally and figuratively zooming in on stunningly beautiful and mysterious Mount Sharp (see our new mosaics above/below), her ultimate destination, while conducting ‘Science on the Go’ with her duo of chemistry labs – SAM and CheMin – and 8 other science instruments as she passes the 2 kilometer driving milestone today; Aug 20 !

“We are holding samples for drops to ChemMin and SAM when the science team is ready for it,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today in an exclusive interview.

“Curiosity has landed in an ancient river or lake bed on Mars,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today.

So, those samples were altered by liquid Martian water – a prerequisite for life.

In fact the car sized rover has saved samples from both the ‘John Klein’ and ‘Cumberland’ drill sites collected previously in the ‘Yellowknife Bay’ area for analysis by the miniaturized labs in the rovers belly -when the time is right.

“Curiosity has stored a Cumberland sample and still has a John Klein sample on board for future use,” Erickson explained.

And that time has now arrived!

“We have put a sample from the Cumberland drill hole into SAM for more isotopic measurements,” reported science team member John Bridges in a blog update on Sol 363, Aug. 14, 2013.

“The sample had been cached within the robotic arm’s turret.”

Curiosity is multitasking – conducting increasingly frequent traverses across the relatively smooth floor of Gale Crater while running research experiments for her science handlers back here on Earth.

She’s captured stunning new views of Mount Sharp – rising 5 km (3 miles) high into the sky – and movies of Mars tiny pair of transiting moons while ingesting new portions of the drilled rock samples acquired earlier this year.

Here’s our video compilation of Phobos and Deimos transiting on Aug 1, 2013

The sample analysis is still in progress.

“The SAM data have not all been received yet,” wrote science team member Ken Herkenhoff in a blog update.

Earlier analysis of sample portions from both ‘John Klein’ and ‘Cumberland’ revealed that the Yellowknife Bay area on Mars possesses the key mineral ingredients proving that Red Planet was once habitable and could have sustained simple microbial life forms.

The scientists are seeking further evidence and have yet to detect organic molecules – which are the building blocks of life as we know it.

Yellowknife Bay resembles a dried out river bed where liquid water once flowed eons ago when the Red Planet was far warmer and wetter than today.

As the 1 ton robot ascends Mount Sharp, she will examine sedimentary layers layed down on ancient Mars over hundreds of millions and perhaps billions of years of past history and habitability.

And just as the rover was celebrating 1 year on Mars on Aug 5/6, she found an intriguing sand dune on Sol 354. See our mosaic

“The rover paused to take images of its tracks after crossing a windblown ripple,” Herkenhoff reported.

As the six wheeled rover approaches Mount Sharp over the next year, she will eventually encounter increasing treacherous dunes that she must cross before beginning her mountain climbing foray.

As of today, Sol 369 (Aug. 20) Curiosity has broken through the 2 kilometer driving mark with a new 70 meter drive, snapped over 75,000 images and fired over 75,000 laser shots.

Mount Sharp is about 8 kilometers (5 miles) distant as the Martian crow flies.

How long will the journey to Mount Sharp require?

“Perhaps about a year,” Erickson told me. “We are trying to make that significantly faster by bringing autonav [autonomous navigation software] online.”

“That will help. But how much it helps really depends on the terrain.”

So far so good.

Meanwhile NASA’s next Mars orbiter called MAVEN (for Mars Atmosphere and Volatile Evolution), recently arrived at the Kennedy Space Center after a cross country flight.

Kennedy technicians are completing assembly and check out preparations for MAVEN’s blastoff to the Red Planet on Nov. 18 from Florida atop an Atlas V rocket similar to the one that launched Curiosity nearly 2 years ago.

And I’ll be at Kennedy to report up close on MAVEN’s launch.

Stay tuned.
