NASA’s SUV-sized Curiosity rover has arrived at a beautiful Martian vista displaying a huge deposit of magnificently petrified sand dunes that look remarkably like some commonly found on Earth and native to the deserts of the U.S. Southwest.

The dunes are keenly fascinating to Red Planet researchers as the NASA robot celebrates 1100 fabulous Sols of exploration and discovery on Mars and contemplates plans for the next drill campaign later this month. See dune mosaic above and our Sol 1100 mosaic below.

The petrified sand dunes were discovered amongst an area of dark sandstone along a ridge at the lower slope of Mars’ Mount Sharp. They are now being explored in detail by the six wheeled rover in a geologic feature dubbed the Stimson unit.

“The team is considering where to drill next within the Stimson sandstone and we are looking for the best light toned areas to check for mineralogical signs of water-rock reaction,” says John Bridges, rover team member from the University of Leicester, England, in the latest mission update from today, September 12, 2015.

Curiosity also discovered large-scale crossbedding in the sandstone that were formed by the action of Martian winds.

“This sandstone outcrop — part of a geological layer that Curiosity’s science team calls the Stimson unit — has a structure called crossbedding on a large scale that the team has interpreted as deposits of sand dunes formed by wind,” according to the rover team.

So Curiosity was commanded by her handlers back on Earth to capture an array of high resolution imagery as part of detailed investigation of the area for up close and contact science.

Dozens of images were taken with the pair of high resolution Mastcam color cameras on the robots mast and combined into the panoramic scene show above and another shown below with a scalebar the length of a tall human, 6.6 feet or 200 centimeters.

The images were taken on Aug. 27, 2015, corresponding to Sol 1087 of the rover’s work on Mars, using both the 34 millimeter-focal-length lens and the 100 mm millimeter-focal-length telephoto Mastcam camera lenses that function as Curiosity’s left and right eyes.

The panorama spans the Martian terrain looking from the east, at left, to the south-southwest at right.

“Some of the dark sandstone in the area …. shows texture and inclined bedding structures characteristic of deposits that formed as sand dunes, then were cemented into rock” say officials.

“Sets of bedding laminations lie at angles to each other.”

Since taking the panorama in late August, the team has driven Curiosity around the area to collect more measurements with her state of the art science instruments.

Later this month, Curiosity will drill into an outcrop at the Stimson unit sandstone for collection and feed it for analysis into the pair of on board chemistry labs – SAM and CheMin- located inside the rover’s belly.

Curiosity already carried out initial contact science in the area by extending the robotic arm to rock targets for investigation with the arm mounted instruments, including the MAHLI camera and APXS spectrometer.

Curiosity “investigated an outcrop of the Stimson unit … and conducted successful contact science,” says Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

Scientists will select the Stimson drill target soon.

Why explore outcrops at Stimson?

“The Stimson unit overlies a layer of mudstone that was deposited in a lake environment. Curiosity has been examining successively higher and younger layers of Mount Sharp, starting with the mudstone at the mountain’s base, for evidence about changes in the area’s ancient environment.”

Curiosity’s prior drill campaign was recently conducted at the “Buckskin” outcrop target in early August 2015. Buckskin was very notable for being the first high silica rock drilling target of the mission.

Stimson and Buckskin sit at the base of Mount Sharp, a huge layered mountain that dominates the center of the 96 mile-wide (154 kilometers-wide) Gale Crater landing site.

Exploring the sedimentary layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rovers long term scientific expedition on the Red Planet.

Curiosity recently celebrated 1000 Sols of exploration on Mars on May 31, 2015 – detailed here with our Sol 1000 mosaic by Marco Di Lorenzo and Ken Kremer also featured at Astronomy Picture of the Day on June 13, 2015.

As of today, Sol 1102, September 12, 2015, she has driven some 6.9 miles (11.1 kilometers) kilometers and taken over 268,000 amazing images.

Curiosity has already accomplished her primary objective of discovering a habitable zone on the Red Planet – at the Yellowknife Bay area – that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

Start Your Day with a Full House – Three Planets and a Pair of Crescents

The Moon, just a couple days before new phase and the upcoming partial solar eclipse, joins Venus and Mars in the dawn sky on Thursday Sept. 10. Well below the triplet, look for returning Jupiter. Source: Stellarium

The dawn sky’s where it’s happening. With Saturn swiftly sinking westward at dusk, bright planets have become scarce in the evening hours. But if you get up early and look east, you’ll discover where the party is. Venus, Mars and now Jupiter have the dance floor.

Tale of two crescents. A montage of the thick crescent Moon and crescent Venus photographed earlier this month. Credit: Tom Ruen

What’s more, the sky gods have seen fit to roll a thin crescent Moon alongside Venus Thursday morning (Sept. 10). This lovely twinning of crescents is best seen about 75 minutes to an hour before sunrise. All you need is a pair of 10x binoculars to see the peewee Venusian version. Its waning crescent phase closely mimics the Moon’s.

From the U.S., the separation between the two will vary from 3° for the East Coast to 4.5° for the West. European and African skywatchers will witness the actual conjunction with the Moon gliding 2.5° north of the planet.

Venus is very bright, making it easy to see in the daytime if you know where to look. Try using the thin Moon soon after sunrise (7:30 a.m. local time shown here) to spot Venus. Aim and focus your binoculars on the Moon, then glide up and to the right to find Venus. If you succeed, lower the binoculars and see if you can spot it without optical aid. Source: Stellarium

Much fainter Mars, checking in at magnitude +1.8, lies 6° to the left or east of the Moon. It thrills me to see Mars begin a new apparition with its return to the morning sky. Next year, the Red Planet reaches opposition on May 22 in the constellation Scorpius, when it will be brighter than Sirius and more than 18 arc seconds across, its biggest and closest since 2005.

Remember Jupiter? We lost it in the solar glare more than a month ago, but if you can find a location with a nice, open eastern horizon, you can welcome the ever-jovial planet back Thursday. Bring binoculars just in case! Jove’s only a few degrees high in moderately-bright twilight.

The bright sunlit crescent contrasts with the darker lighting of twice-reflected light supplied by sunlight reflecting off our own planet. Credit: Bob King — The bright sunlit crescent contrasts with the darker lighting of twice-reflected light contributed by own planet. Credit: Bob King

When you look at the Moon Thursday, most of it will be illuminated not by sunlight but by Earth-light called earthshine. This smoky, dark glow results from sunlight bouncing off the globe into space to softly light the otherwise shadowed portion of the Moon. The effect is most pleasing to the eye and remarkable in binoculars, which reveal lunar seas and even larger craters shrouded in blue-dark. Don’t miss it!

When it comes to space exploration it’s resoundingly clear that rock band ‘One Direction’ is headed in the right direction – To Infinity and Beyond! – with the release of their new NASA themed music video ‘Drag Me Down.’

The new single – ‘Drag Me Down’ – by the world famous boy band is out now and out of this world!

Just click on the Vevo video above and enjoy their musical tour through space exploration themed videos filmed on location at NASA facilities, including the Johnson Space Center – home to astronauts training to explore ‘Where No One Has Gone Before.’

Over 18,100,000 views so far!! Millions of eyeballs exposed to NASA activities like never before!

As you’ll see in the video (published on Aug. 20) the quartet got a first hand look at a host of NASA’s cutting edge technology and hardware like NASA’s Orion deep space crew capsule that’s destined to propel our astronauts back to deep space and explore wondrous destinations including the Moon, asteroids and the Red Planet, as part of the agency’s ‘Journey to Mars’ initiative.

Motivating our young people to study and excel in math, science, engineering, technology and the arts is what it’s all about to inspire the next generation of explorers and advance all humanity to fulfilling and prosperous lives.

“#DragMeDownMusicVideo @space_station Gravity can’t drag me down! Great to see @NASA inspire our next gen #YearInSpace,” tweeted NASA astronaut Scott Kelly currently working aboard the International Space Station.

Lets join “One Direction’s” space tour.

So the guys donned NASA’s spacesuits as they began ‘training’ to fly aboard NASA’s Orion spaceship.

Orion flew its first uncrewed mission on the EFT-1 flight in December 2014, launching aboard a United Launch Alliance Delta IV Heavy rocket.

Harry, Niall, Louis and Liam all got suited up to check out and sit inside an Orion trainer. Next you’ll see them ‘blast off’ for space atop the Delta IV rocket from the Florida Space Coast in their music video.

But first they rollick with the astronauts T-38 training jets which are used by real-life astronauts to practice spacecraft operations at supersonic speeds up to Mach 1.6 and experience blistering accelerations of more than seven Gs!

Here we join Louis to rove around Johnson Space Center in NASA’s Space Exploration Vehicle that will one day be used for awe-inspiring interplanetary journey’s to the surface of alien bodies like the moon, near-Earth asteroids and Mars!

Even though Louis is roving around Johnson Space Center in our Space Exploration Vehicle, its intended destination is quite different. The SEV will be used for in-space missions and for surface explorations of planetary bodies, including near-Earth asteroids and Mars!

Wouldn’t you like to join Louis!

Meanwhile Harry got to hang out with Robonaut at the Johnson Space Center during the filming of the music video.

Simultaneously the Robonauts twin brother, Robonaut 2, is hanging out in space right now with other humans. Robonaut 2 is working side-by-side with NASA astronauts Scott Kelly and Kjell Lindgren and the rest of the six man crew floating aboard the International Space Station and soaring some 250 miles (400 kilometers) overhead.

“Going where the risks are too great for people, robots will make it so we never get ‘dragged down’!” says NASA.

“Currently living in space, @StationCDRKelly is 1 of 6 people that literally cannot be dragged down. #DragMeDown,” NASA tweeted.

And here’s Niall experiencing reduced gravity in the Partial Gravity Simulator & Space Station Mockup Bike. This simulator is where astronauts learn how to work effectively in the partial gravity of space and on the surface of other worlds

I’ve been a fan of ‘One Direction’ and now nothing will ‘hold me back’ following #DragMeDown.

And don’t forget that you can watch Commander Scott Kelly and his five international crew mates on a regular basis as they soar overhead. Just click on NASA’s Spot the Station link and plug in your location.

And make sure you sign up to ‘Send Your Name to Mars’ on InSight – NASA’s next Mars Lander. The deadline is Sept 8 – sign up details in my story here.

Orion’s inaugural mission dubbed Exploration Flight Test-1 (EFT) was successfully launched on a flawless flight on Dec. 5, 2014 atop a United Launch Alliance Delta IV Heavy rocket Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

Here’s what the real Orion EFT-1 looked like after the mission was successfully completed and it was recovered from splashdown in the Pacific Ocean.

Right now NASA is building the next Orion.

If you desire to be aboard a future Orion, don’t let anything ‘Drag You Down.’

And tell Congress and the White House to ‘Support Full Funding for NASA!’ – – Because Congress has significantly slashed funding for the commercial crew capsules in the upcoming 2016 Fiscal Year budget!

Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.

Tricks to Remember the Planets

Need an easy way to remember the order of the planets in our Solar System? The technique used most often to remember such a list is a mnemonic device. This uses the first letter of each planet as the first letter of each word in a sentence. Supposedly, experts say, the sillier the sentence, the easier it is to remember.

So by using the first letters of the planets, (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), create a silly but memorable sentence.

Here are a few examples:

My Very Excellent Mother Just Served Us Noodles (or Nachos)
Mercury’s Volcanoes Erupt Mulberry Jam Sandwiches Until Noon
Very Elderly Men Just Snooze Under Newspapers
My Very Efficient Memory Just Summed Up Nine
My Very Easy Method Just Speeds Up Names
My Very Expensive Malamute Jumped Ship Up North

If you want to remember the planets in order of size, (Jupiter, Saturn, Uranus, Neptune, Earth, Venus Mars, Mercury) you can create a different sentence:
Just Sit Up Now Each Monday Morning
Jack Sailed Under Neath Every Metal Mooring
Rhymes are also a popular technique, albeit they require memorizing more words. But if you’re a poet (and don’t know it) try this:

Amazing Mercury is closest to the Sun,
Hot, hot Venus is the second one,
Earth comes third: it’s not too hot,
Freezing Mars awaits an astronaut,
Jupiter is bigger than all the rest,
Sixth comes Saturn, its rings look best,
Uranus sideways falls and along with Neptune, they are big gas balls.

Or songs can work too. Here are a couple of videos that use songs to remember the planets:

If sentences, rhymes or songs don’t work for you, perhaps you are more of a visual learner, as some people remember visual cues better than words. Try drawing a picture of the planets in order. You don’t have to be an accomplished artist to do this; you can simply draw different circles for each planet and label each one. Sometimes color-coding can help aid your memory. For example, use red for Mars and blue for Neptune. Whatever you decide, try to pick colors that are radically different to avoid confusing them.

Or try using Solar System flash cards or just pictures of the planets printed on a page (here are some great pictures of the planets). This works well because not only are you recalling the names of the planets but also what they look like. Memory experts say the more senses you involve in learning or storing something, the better you will be at recalling it.

Maybe you are a hands-on learner. If so, try building a three-dimensional model of the Solar System. Kids, ask your parents or guardians to help you with this, or parents/guardians, this is a fun project to do with your children. You can buy inexpensive Styrofoam balls at your local craft store to create your model, or use paper lanterns and decorate them. Here are several ideas from Pinterest on building a 3-D Solar System Model.

If you are looking for a group project to help a class of children learn the planets, have a contest to see who comes up with the silliest sentence to remember the planets. Additionally, you can have eight children act as the planets while the rest of the class tries to line them up in order. You can find more ideas on NASA’s resources for Educators. You can use these tricks as a starting point and find more ways of remembering the planets that work for you.

If you are looking for more information on the planets check out Universe Today’s Guide to the Planets section, or our article about the Order of the Planets, or this information from NASA on the planets and a tour of the planets.

Universe Today has numerous articles on the planets including the planets and list of the planets.

Astronomy Cast has an entire series of episodes on the planets. You can get started with Mercury.

Curiosity Snaps Stunning One of a Kind Belly Selfie At Buckskin Mountain Base Drill Site

This low-angle self-portrait of NASA’s Curiosity Mars rover shows the vehicle at the site from which it reached down to drill into a rock target called “Buckskin.” The MAHLI camera on Curiosity’s robotic arm took multiple images on Aug. 5, 2015, that were stitched together into this selfie. Credits: NASA/JPL-Caltech/MSSS
More selfie and drilling mosaics below[/caption]

NASA’s Curiosity rover has snapped a stunningly beautiful, one of a kind ‘belly selfie’ amidst the painstaking ‘Buckskin’ drill campaign at the Martian mountain base marking the third anniversary since her touchdown on the Red Planet.

The unique self portrait was taken from a low-angle for the first time and shows the six wheeled rover at work collecting her seventh drilled sample at the ‘Buckskin’ rock target earlier this month in the “Marias Pass” area of lower Mount Sharp.

‘Buckskin’ is also unique in a fabulously scientifically way because the rover discovered a new type of Martian rock that’s surprisingly rich in silica – and unlike any other targets found before.

The low camera angle is what enables the awesome Buckskin belly selfie. It’s a distinctively dramatic view and actually stitched from 92 images captured by the Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, or Sol 1065 of the mission.

The high resolution MAHLI color camera is located on the end of the 7 foot-long (2.1 meter-long) robotic arm.

This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called "Buckskin" is presented as a stereographic projection, which shows the horizon as a circle. The MAHLI camera on Curiosity's robotic arm took dozens of component images for this selfie on Aug. 5, 2015.

Indeed the car-sized rover has taken spectacular selfies several times before during her three year long trek across the Martian surface, since the August 2012 landing inside Mars’ Gale Crater. But for those past selfies the MAHLI camera was hoisted higher to give the perspective of looking somewhat downward and showing the rovers top deck and trio of sample inlet ports.

In this case, the rover team specifically commanded Curiosity to position “the camera lower in relation to the rover body than for any previous full self-portrait of Curiosity,” said NASA officials.

Two patches of gray colored powdered rock material drilled from Buckskin are visible in the selfie scene, in front of the rover.

“The patch closer to the rover is where the sample-handling mechanism on Curiosity’s robotic arm dumped collected material that did not pass through a sieve in the mechanism. Sieved sample material was delivered to laboratory instruments inside the rover. The patch farther in front of the rover, roughly triangular in shape, shows where fresh tailings spread downhill from the drilling process.”

Prior selfies were taken at the “Rocknest” (http://photojournal.jpl.nasa.gov/catalog/PIA16468), “John Klein” (http://photojournal.jpl.nasa.gov/catalog/PIA16937), “Windjana” (http://photojournal.jpl.nasa.gov/catalog/PIA18390) and “Mojave” drill sites.

Basically in the Sol 1065 belly selfie at “Buckskin” we see the underbelly of the rover and all six wheels along with a complete self portrait.

On several prior occasions, MAHLI was used to image just the underbelly and wheels to aid in inspecting the wheels to look for signs of damage inflicted by sharp-edged Martian rocks poking holes in the aluminum wheels.

Each wheel measures 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. And the MAHLI monitoring images have shown the effects of increasing wear and tear that ultimately forced the rover drivers to alter Curiosity’s driving route on the crater floor in favor of smoother and less rocky terrain imparting less damage to the critical wheels.

If you take a close look at the new selfie up top, you’ll see a small rock stuck onto Curiosity’s left middle wheel (on the right in this head-on view). The rock was seen also in prior wheel monitoring images taken three weeks ago.

“The selfie at Buckskin does not include the rover’s robotic arm beyond a portion of the upper arm held nearly vertical from the shoulder joint. With the wrist motions and turret rotations used in pointing the camera for the component images, the arm was positioned out of the shot in the frames or portions of frames used in this mosaic,” according to officials.

The drilling campaign into “Buckskin” was successfully conducted on Sol 1060 (July 30, 2015) at the bright toned “Lion” outcrop to a full depth of about 2.6 inches (6.5 centimeters) and approximately 1.6 cm (0.63 inch) diameter.

You can also see another perspective of the rover at work while reaching out with the robotic arm and drilling into ‘Buckskin’ as illustrated in our mosaics of mastcam and navcam camera raw images created by the image processing team of Ken Kremer and Marco Di Lorenzo.

The main bore hole was drilled next to the initial mini hole test and shows the indicative residue of grey colored tailings from the Martian subsurface seen distributed around the new hole.

Curiosity has now moved on from the “Marias Pass” area.

Curiosity recently celebrated 1000 Sols of exploration on Mars on May 31, 2015 – detailed here with our Sol 1000 mosaic also featured at Astronomy Picture of the Day on June 13, 2015.

As of today, Sol 1080, August 20, 2015, she has driven some 6.9 miles (11.1 kilometers) kilometers and taken over 260,000 amazing images.

NASA Invites Public to ‘Send Your Name to Mars’ on InSight – Next Red Planet Lander

Sign up to send your name to Mars on InSight, NASA’s next mission to Mars launching in March 2016. Credit: NASA
Sign up link below – don’t delay![/caption]

Calling space fans worldwide: Now is your chance to participate in NASA’s human ‘Journey to Mars’ initiative and NASA’s next robotic mission to Mars – the InSight lander launching to the Red Planet next spring.

NASA invites you to ‘Send Your Name to Mars’ on a silicon microchip aboard the InSight probe slated for blastoff on March 4, 2016 from Vandenberg Air Force Base, California.

InSight’s science goal is totally unique – to “listen to the heart of Mars to find the beat of rocky planet formation.”

The public can submit their names for inclusion on a dime-sized microchip that will travel on a variety of spacecraft voyaging to destinations beyond low-Earth orbit, including Mars.

“Our next step in the journey to Mars is another fantastic mission to the surface,” said Jim Green, director of planetary science at NASA Headquarters in Washington.

“By participating in this opportunity to send your name aboard InSight to the Red Planet, you’re showing that you’re part of that journey and the future of space exploration.”

In just the first 24 hours over 67,000 Mars enthusiasts have already signed up!

But time is of the essence since the deadline to submit your name is soon: Sept. 8, 2015.

How can you sign up to fly on InSight? Is there a certificate?

NASA has made it easy to sign up.

To send your name to Mars aboard InSight, click on this weblink posted online by NASA:

http://go.usa.gov/3Aj3G

And you can also print out an elegant looking ‘Boarding Pass’ that looks like this:

Furthermore the ‘Boarding Pass’ also comes with a listing of your “frequent flier” points accumulated by your participation in NASA’s ‘fly-your-name opportunity’ that will span multiple missions and multiple decades beyond low Earth orbit.

InSight represents the second ‘fly-your-name opportunity’ in NASA’s journey to Mars program. The uncrewed Orion EFT-1 mission launched on Dec. 5, 2014 was the first chance for space fans to collect ‘Journey to Mars’ points by sending your names to space.

The ‘Send Your Name to Mars’ campaign for Orion EFT-1 was a huge success.

Over 1.38 million people flew on the silicon chip aboard the maiden flight of Orion, the NASA capsule that will eventually transport humans to the Red Planet in the 2030s.

Don’t dawdle. Because after InSight, you’ll have to wait about three years until late 2018 and the blastoff of the next Orion capsule on NASA’s Exploration Mission-1 (EM-1) for you next chance to accumulate “frequent flier” points on a ‘Journey to Mars’ mission.

Orion EM-1 will launch atop NASA’s mammoth Space Launch System (SLS) rocket, and NASA just conducted a key test firing on Aug. 13 of the first stage engines that will power the stack to on a mission to the Moon – detailed in my recent story here.

InSight, which stands for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport, is a stationary lander.

It will join NASA’s surface science exploration fleet currently comprising of the Curiosity and Opportunity missions which by contrast are mobile rovers.

InSight is the first mission to understand the interior structure of the Red Planet. Its purpose is to elucidate the nature of the Martian core, measure heat flow and sense for “Marsquakes.”

“It will place the first seismometer directly on the surface of Mars to measure Martian quakes and use seismic waves to learn about the planet’s interior. It also will deploy a self-hammering heat probe that will burrow deeper into the ground than any previous device on the Red Planet. These and other InSight investigations will improve our understanding about the formation and evolution of all rocky planets, including Earth,” says NASA.

The countdown clock is ticking relentlessly towards liftoff in less than seven months time in March 2016.

Insight promises to ‘science the sh**’ out of the heart of Mars!

It is funded by NASA’s Discovery Program as well as several European national space agency’s and countries. Germany and France are providing InSight’s two main science instruments; The HP3 heat probe and the SEIS seismometer through the Deutsches Zentrum für Luft- und Raumfahrt. or German Aerospace Center (DLR) and the Centre National d’Etudes Spatiales (CNES).

“Together, humans and robotics will pioneer Mars and the solar system,” says Green.

Watch the You-Know-What Out Of This New Trailer for The Martian

The second full trailer for 20th Century Fox’s upcoming film The Martian dropped this morning and it looks like a whole red-planetful of awesome space adventure! Directed by Ridley Scott and based on the runaway hit novel of the same name by Andy Weir, The Martian stars Matt Damon as Mark Watney, a member of a fictional yet not-too-distant-future NASA mission to explore the surface of Mars. After a violent dust storm batters the camp the team is forced to abort the mission, abandoning the base and Watney, who was injured and assumed dead. Except, of course, he’s not, thus beginning his new mission to remain alive on Mars long enough to be rescued — a feat which will require bravery, brains, luck… and a whole you-know-what-load of science. (If you haven’t read the book yet, it’s a lot of fun. I highly suggest it.) So check out the trailer above, and feel free to repeat as necessary.

India’s space agency has released a spectacular new batch of images taken by everyone’s favorite MOM – the Mars Orbiter Mission – the nation’s first probe ever dispatched to the Red Planet and which achieved orbit nearly a year ago.

The Indian Space Research Organization (ISRO) has published a beautiful gallery of images featuring a steep and stunning Martian canyon and the landing site of NASA’s Curiosity Mars Science Laboratory rover, and more.

The lead image was taken over the Ophir Chasma canyon on the Martian surface by the Mars Colour Camera aboard India’s Mars Orbiter Mission.

Ophir Chasma is a canyon in the Coprates quadrangle located at 4° south latitude and 72.5° west longitude. It is part of the Valles Marineris – the ‘Grand Canyon of Mars’ – and the largest known canyon in the Solar System.

The image was captured on July 19, 2015 from an altitude of 1857 kilometers (1154 miles). It has with a resolution of 96 meters.

The steep walled Ophir Chasma canyon contains many layers and the floors contain large deposits of layered materials, perhaps even sulfates.

Ophir Chasma is about 317 kilometers long and about 8 to 10 kilometers deep located near the center of Valles Marineris – see map below.

Valles Marineris stretches over 4,000 km (2,500 mi) across the Red Planet, is as much as 600 km wide and measures as much as 10 kilometers (6 mi) deep. It is nearly as wide as the United States.

Here’s an illuminating and magnificent 3D portrayal of Ophir Chasma created by Indian scientists that gives a sense of the canyons scale, sheer walls and cliffs and depth:

The newest images were snapped after the spacecraft exited the communications blackout encountered by all of Earth’s invasion fleet of Red Planet orbiters and rovers during the recent conjunction period when Mars was behind the sun during much of June.

ISRO also released a delightful new image of Gale Crater and the surrounding vicinity.

Gale Crater is the landing site of NASA’s Curiosity rover. MOM took the image from an altitude of 9004 kilometers.

Gale Crater is home to humongous Mount Sharp, a mountain that rises 5.5 kilometers (3.4 miles) from the crater floor and is easily visible in the photo from MOM. The crater is 154 kilometers (96 mi) wide.

Curiosity is currently exploring the foothills of Mount Sharp around the top of the image – which shows a rather different perspective from what we’ve seen from prior familiar orbital imagery snapped by several NASA and ESA orbiters.

The 1 ton rover recently celebrated the 3rd anniversary since its nailbiting touchdown inside Gale crater. And the new wider angle image from MOM gives a fabulous sense of exactly why a highly precise landing was essential – otherwise it would have been doomed.

Curiosity recently drilled into the “Buckskin” target at an outcrop at the foothills of Mount Sharp. See the mountain in our ground level mosaic from the crater floor. And its kind of neat to actually imagine Curiosity sitting there while perusing MOM’s photo.

MOM’s goal is to study Mars atmosphere, surface environments, morphology, and mineralogy with a 15 kg (33 lb) suite of five indigenously built science instruments. It is also sniffing for methane, a potential marker for biological activity.

MOM is India’s first deep space voyager to explore beyond the confines of her home planets influence and successfully arrived at the Red Planet after the “history creating” orbital insertion maneuver on Sept. 23/24, 2014 following a ten month journey from Earth.

The Indian probe arrived just after NASA’s MAVEN Mars orbiter, the first mission specifically targeted to study Mars tenuous upper atmosphere and the escape rates of atmospheric constituents.

MOM swoops around Mars in a highly elliptical orbit whose nearest point to the planet (periapsis) is at about 421 km and farthest point (apoapsis) at about 76,000 km, according to ISRO.

It takes MOM about 3.2 Earth days or 72 hours to orbit the Red Planet.

MOM was launched on Nov. 5, 2013 from India’s spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous four stage Polar Satellite Launch Vehicle (PSLV) which placed the probe into its initial Earth parking orbit.

The $73 million MOM mission was expected to last at least six months. In March, ISRO extended the mission duration for another six months since its healthy, the five science instruments are operating fine and it has sufficient fuel reserves.

Including MOM, Earth’s invasion fleet at the Red Planet numbers a total of seven spacecraft comprising five orbiters from NASA, ESA and ISRO as well as the sister pair of mobile surface rovers from NASA – Curiosity and Opportunity.

Milestone Test Firing of NASA’s SLS Monster Rocket Engine Advances Human Path to Deep Space

During a 535-second test on August 13, 2015, operators ran the Space Launch System (SLS) RS-25 rocket engine through a series of tests at different power levels to collect engine performance data on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Credit: NASA

With today’s (Aug. 13) successful test firing of an RS-25 main stage engine for NASA’s Space Launch System (SLS) monster rocket currently under development, the program passed a key milestone advancing the agency on the path to propel astronauts back to deep space at the turn of the decade.

The 535 second long test firing of the RS-25 development engine was conducted on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – and ran for the planned full duration of nearly 9 minutes, matching the time they will fire during an actual SLS launch.

All indications are that the hot fire test apparently went off without a hitch, on first look.

“We ran the full duration and met all test objectives,” said Steve Wofford, SLS engine manager, on NASA TV following today’s’ test firing.

“There were no anomalies.” – based on the initial look.

The RS-25 is actually an upgraded version of former space shuttle main engines that were used with a 100% success rate during NASA’s three decade-long Space Shuttle program to propel the now retired shuttle orbiters to low Earth orbit. Those same engines are now being modified for use by the SLS.

“Data collected on performance of the engine at the various power levels will aid in adapting the former space shuttle engines to the new SLS vehicle mission requirements, including development of an all-new engine controller and software,” according to NASA officials .

The engine controller functions as the “brain” of the engine, which checks engine status, maintains communication between the vehicle and the engine and relays commands back and forth.

The core stage (first stage) of the SLS will be powered by four RS-25 engines and a pair of the five-segment solid rocket boosters that will generate a combined 8.4 million pounds of liftoff thrust, making it the most powerful rocket the world has ever seen.

Since shuttle orbiters were equipped with three space shuttle main engines, the use of four RS-25s on the SLS represents another significant change that also required many modifications being thoroughly evaluated as well.

The SLS will be some 10 percent more powerful than the Saturn V rockets that propelled astronauts to the Moon, including Neil Armstrong, the human to walk on the Moon during Apollo 11 in July 1969.

SLS will loft astronauts in the Orion capsule on missions back to the Moon by around 2021, to an asteroid around 2025 and then beyond on a ‘Journey to Mars’ in the 2030s – NASA’s overriding and agency wide goal.

Each of the RS-25’s engines generates some 500,000 pounds of thrust. They are fueled by cryogenic liquid hydrogen and liquid oxygen. For SLS they will be operating at 109% of power, compared to a routine usage of 104.5% during the shuttle era. They measure 14 feet tall and 8 feet in diameter.

They have to withstand and survive temperature extremes ranging from -423 degrees F to more than 6000 degrees F.

This video shows the full duration hot-fire test:

NASA has 16 of the RS-25s leftover from the shuttle era and they are all being modified and upgraded for use by the SLS rocket.

Today’s test was the sixth in a series of seven to qualify the modified engines to flight status. The engine ignited at 5:01 p.m. EDT and reached the full thrust level of 512,000 pounds within about 5 seconds.

The hot gas was exhausted out of the nozzle at 13 times the speed of sound.

Since the shuttle engines were designed and built over three decades ago, they are being modified where possible with state of the art components to enhance performance, functionality and ease of operation, by prime contractor Aerojet-Rocketdyne of Sacramento, California.

One of the key objectives of today’s engine firing and the entire hot fire series was to test the performance of a brand new engine controller assembled with modern manufacturing techniques.

“Operators on the A-1 Test Stand at Stennis are conducting the test series to qualify an all-new engine controller and put the upgraded former space shuttle main engines through the rigorous temperature and pressure conditions they will experience during a SLS mission,” says NASA.

“The new controller, or “brain,” for the engine, which monitors engine status and communicates between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status.’

“The RS-25 is the most complicated rocket engine out there on the market, but that’s because it’s the Ferrari of rocket engines,” says Kathryn Crowe, RS-25 propulsion engineer.

“When you’re looking at designing a rocket engine, there are several different ways you can optimize it. You can optimize it through increasing its thrust, increasing the weight to thrust ratio, or increasing its overall efficiency and how it consumes your propellant. With this engine, they maximized all three.”

Engineers will now pour over the data collected from hundreds of data channels in great detail to thoroughly analyze the test results. They will incorporate any findings into future test firings of the RS-25s.

NASA says that testing of RS-25 flight engines is set to start later this fall.

“The RS-25 engine gives SLS a proven, high performance, affordable main propulsion system for deep space exploration. It is one of the most experienced large rocket engines in the world, with more than a million seconds of ground test and flight operations time.”

NASA plans to buy completely new sets of RS-25 engines from Aerojet-Rocketdyne taking full advantage of technological advances and modern manufacturing techniques as well as lessons learned from this hot fire series of engine tests.

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

Revealed: Mars to Appear Larger Than a Full Moon!

A recipe for a three ring circus? Image credit:

We can finally reveal the truth.

A massive conspiracy, spanning over a decade, has been revealed at last by basement bloggers, YouTubers and Facebook users everywhere, implicating ‘big-NASA’ and the powers that be in a massive cover-up.

Yes, it’s the month of August once again, and the Red Planet Mars is set to appear ‘larger than a Full Moon’ over the skies of Earth, as it apparently does now… every year.

Um, no. Stop. Just… stop.

Sure, by now, you’ve had the hoax forwarded to you by that certain well-meaning, but astronomically uninformed family member/co-worker/anonymous person on Facebook.

What’s new under the Sun concerning the August Mars Hoax? To see where the hoax was born, we have to journey all the way back to the close opposition of Mars on August 27^th, 2003. Hey, we actually took two weeks leave in the Fall of 2003 just to sketch and image Mars each night from our backyard lair in the Sonoran desert south of Tucson, Arizona from the then known Very Small Optical Observatory. Those were the days. We measured dial-up internet speeds in kbit/s, ‘burned CDs,’ and Facebook and Twitter were still some years away. Even spam e-mail was still sorta hip.

Two years later in 2005, we were all amused, as the ‘August Mars Hoax’ chain email made its first post-2003 appearance in our collective inboxes. Heck, we were even eager in those halcyon days to take to the nascent web, and do that new hipster thing known as ‘blogging’ to explain just exactly why this couldn’t be so to the masses.

Later in 2006, 2007, and 2008, it wasn’t so funny.

The Mars Hoax just wouldn’t die. “One more unto the breach,” the collective astro-blogging community sighed, as we all dusted off last year’s post explaining how the Red Planet could never approach our own fair world so closely.

It. Just. Couldn’t. Because orbital mechanics. Because physics.

Even the advent of social media couldn’t kill in annual onslaught of the Mars Hoax, and over a Spiderman movie reboot later, we’re now seeing it shared across Facebook, Twitter and more.

Sure, the Mars Hoax is as fake as Donald Trump’s hair. If there’s any true science lesson to learn here, it’s perhaps the mildly interesting social science study of just how the Mars hoax weathers the lean months of winter, to reemerge every August.

Here’s the skinny (again!) on just why Mars can’t appear as large as the Full Moon:

-The Moon is 3,474 kilometers in diameter, and orbits the Earth at an average distance of just under 400,000 kilometers.

-At this distance, the Moon can only appear about 30’ (half a degree) across.

-Think that’s a lot? Well, you could ring the 360 degree circle of the local horizon with 720 Full Moons.

-Mars, like the Earth, orbits the Sun. Even with Earth at aphelion (its most distant point) and Mars at perihelion, we’re still 206.7 – 151.9 = 54.8 million km apart. Sure, aphelion and perihelion of our respective worlds don’t quite line up in our current epochs, but we’ll indulge imagination and fudge things a bit.

-Though Mars is just over 2x times larger in diameter than the Moon, it’s also more than 143 times farther away, even at its said hypothetical closest.

-Still want to see Mars as big as a Full Moon? Perhaps one day, astronauts will, though they’ll have to be orbiting just over a 800,000 km from the Red Planet to do it.

If we sound a little pessimistic in our characterizing the Mars Hoax as a recurring non-story, it’s because we see many truly fantastic things in space news that get far from their far shake. Real stories, of collapsing stars, rogue exoplanets, and intrepid rovers exploring distant worlds. Tales of humanoids, exploring space and doing the very best and noble things humanoids as a species can do.

Want to trace the history the Mars Hoax?

Here’s the saga of Universe Today’s coverage of all things ‘Mars Hoax’ since those olden days of the early web:

2005- No, Mars Won’t Look as Big as the Moon

2006- No, Mars Won’t Look as Big as the Moon in August

2007- Will Mars Look as Big as the Moon on August 27? Nope

2008- Please (Again) – Mars Will NOT Look as Big as the Full Moon

2009- Mars Will NOT Look as Big as the Full Moon… But You Can Watch it Get Closer

2010- Tonight’s the Night Mars Will NOT Look as Big as the Full Moon

2011- Is the Moon Mars Myth Over?

2013- The Cyber Myth that Just Won’t Die

2016- ????

Hey, it looks like the hoax did take a break in 2012 and 2014, so that’s encouraging at least…

Now, I’m going to do my best to truly terrify all of science blogger-dom, and leave you with one final thought to consider. Mars reaches opposition (otherwise known in astronomical circles as ‘when it’s really nearest to the Earth’) once roughly every 26 months. All oppositions of Mars are not created equal, owing mostly to the eccentric orbit of the Red Planet. We have another fine opposition of Mars coming right up next year on May 22^nd, 2016, followed by one that’s very nearly as favorable as the historic 2003 opposition in 2018, falling juuuuust shy of August on July 28^th of that year…

Will the Mars Hoax meme find a new unwitting audience, and with it, new life?

Sleep tight…. we’ll be covering real science stories in the meantime, ’til we’re called to do battle with the Mars Hoax once again.
