There’s Poop on the Moon

When the Apollo boys visited the Moon back in the ’60s and ’70s they left more than just some experiments, rovers, and family portraits behind –- they also left, shall we say, a little bit of themselves on the lunar surface. It makes total sense when you think about it, but still… there’s poop on the Moon.

In this video, Minute Physics and Destin from Smarter Every Day show how astronauts would relieve themselves during the Apollo missions (or at least the gadgets they used — we all know how they did it) and why it was decided to make astronaut poop a permanent part of their lunar litter.

(Because there’s no public toilets in the Sea of Tranquility.)

In another video Destin goes on to discuss some of the other things the Apollo astronauts left on the lunar surface as part of their… duties… most notably the Laser Ranging Retroreflectors that are still being used today to measure distances between Earth and the Moon. Destin explains how their corner-cube reflectors work — using, fittingly, the mirrors in a restroom shared with NASA at the University of Alabama at Huntsville. Check out the video below.

According to the Lunar and Planetary Institute: “The Laser Ranging Retroreflector experiment has produced many important measurements. These include an improved knowledge of the Moon’s orbit and the rate at which the Moon is receding from Earth (currently 3.8 centimeters per year) and of variations in the rotation of the Moon. These variations in rotation are related to the distribution of mass inside the Moon and imply the existence of a small core, with a radius of less than 350 kilometers, somewhat smaller than the limits imposed by the passive seismic and magnetometer experiments. These measurements have also improved our knowledge of changes of the Earth’s rotation rate and the precession of its spin axis and have been used to test Einstein’s theory of relativity.”

Just goes to show that not everything that got left behind was crap.

Q & A with Astronaut Jerry Ross, Record-Setting Frequent Space Flyer

If there was a frequent flyer program for astronauts, Jerry Ross would be a gold status member. Ross is a veteran of seven space shuttle missions, making him a co-record holder for most spaceflights with fellow former NASA astronaut Franklin Chang-Diaz, and with nine spacewalks, he has the second most EVAs by a NASA astronaut. He is one of only three astronauts to have served throughout the entire Space Shuttle Program. Ross has written a new book about his life and career as an astronaut, “Spacewalker: My Journey in Space and Faith as NASA’s Record-Setting Frequent Flyer.” This is the first time he has told his story, reflecting on the legacy of the Shuttle program, its highs and lows, and the future of manned space flight.

Ross talked with Universe Today about his experiences and his new book. (Find out how you can win a copy of the book here.)

Universe Today: What made you decide to write a book about your experiences?

Jerry Ross: I wanted to share my experiences of what it was like to suit up to go out on a spacewalk and also help people understand what it is like to be an astronaut, that we are regular people who do regular work most of the time and only get to fly in space once in a while. In addition I wanted to entertain a little, use some funny stories that I had told many times to my friends when we were down at the Cape waiting for a launch, and a lot of times people would say, ‘those are great stories, you ought to write a book.’ After more and more people said that I started to take it a little more seriously.

Additionally I wrote it for my granddaughters who were young enough while I was still flying in space to not remember much, and in fact the youngest one was born after I had completed my flying. But probably the most important reason is that throughout my astronaut career I made a point that while I was talking with young students about their lives and what they could do with their God-given talents and capabilities, that they should dream large, study hard and work hard to reach their goals and not give up too easily. Throughout many of my talks over the years at schools, I have used my own career as a way of pointing out to them that, yeah, you are going to have some setbacks, your life won’t go in a straight line. You’ll have to study hard and work hard but you don’t have to be a straight-A student. And don’t give up too easily on what your goals are. I am one of the very fortunate ones who was able realize very early in my life what I wanted to do. I was able to set those goals and was able to achieve them, and what happened in my life was so much better than I could have dreamed about!

UT: You are obviously very dedicated to NASA. How does it feel to have the spaceflight records you have, and to have been a part the agency that is such an iconic part of America?

JR: The records are a byproduct of the what I said before; working hard and not giving up. I am and I was very dedicated to what our country was doing in space but I am somewhat frustrated that we are not doing more now. The records are quite frankly something that I wish I could have pushed much higher. I would have hoped to have flown many more times and done more spacewalks as well. Frankly, I’m disappointed that my records haven’t fallen and that those records aren’t continuing to be broken.

If we’re not continuing to push forward in space and do things more routinely and more aggressively, then as a country we are failing to be the leaders of the world that we should be in terms of leading humankind further into the Universe, learning more about the Universe and about ourselves, and potentially being able to live on other planets someday. While the records are nice — and it is kind of nice to put that in your bio that you hold the world record — it is not something that I hang onto, and like I said, I hope we will get back into a much more aggressive program that will push more people into space faster and farther.

UT: Do you have a favorite mission or favorite moment that you cherish from all your spaceflights?

JR: That question is just like asking a mother which one of her seven children she likes best! Every one of my flights was unique and different. All of them were a lot of fun with great crews and great missions. If I had to pick one, it would probably be the first flight, just because it was my first. It was an exciting mission, a great crew and I got to go on my first spacewalk, which laid the foundation for even more spacewalks in the future. At the time I launched I was already assigned to another mission, so it was a great time in my career when I was still fairly young but was really starting to feel the success of all the hard work.

UT: What was the most unexpected thing or experience you had?

JR: I think the most unexpected thing — and I talk about it in the book — is the epiphany I had on my fourth spacewalk on my third space shuttle mission when I was high above the payload on a foot restraint on the end of the robotic arm. The rest of the crew was concentrating on working with (astronaut) Jay Asp who was doing some work in the payload bay. I had the chance to look into deep space. It was at night and I turned off my helmet-mounted lights and just looked at the Universe and the uncountable number of stars out there. And all of a sudden I had this sense come over me — it was totally unexpected, it wasn’t something I was thinking about or contemplating — but it was a sense that I was doing what God had intended me to do, being in space in a spacesuit, working to fix satellites and assemble things in space. What a reassurance that you picked the right path, and that you are doing exactly what you were intended to do!

For an engineer to have any feelings at all, and especially a feeling like that traveling at 5 miles a second above the Earth is pretty incredible.

UT: I really enjoyed the sidebar pieces in the book that were written by the people important in your life – your friend Jim, and your wife and children. How did you decide to include that, and did you have any trouble convincing them to be a part of the book?

JR: The book started out with John Norberg, my co-writer, coming down and doing a series of interviews with me and also with my family members and my best friend Jim Gentleman, and one of my two sisters in Indiana. Initially, John was going to write more of the book than it ended up being. It was a much more collaborative effort than I had anticipated. But those sidebars or insights from others was totally his idea and one that I entirely latched onto once we started writing. I think it is a great insight into the rest of the family and how we operated as a family. I’ve had this comment multiple times now from folks that these additional insights were especially enjoyable.

UT: Your daughter Amy also works at NASA, and has helped to create better gloves for spacewalking. How gratifying is that to have her be a part of NASA?

JR: I think any parent is pleased if one of their children decides to follow in their footsteps. I guess that somehow validates that what the parent has been doing was something they valued and thought was interesting and exciting. Amy was exposed to it and was never encouraged one way or the other to be part of NASA or not, so it was very satisfying to see her do that. It was equally gratifying for me for my wife Karen to get into the space program working for United Space Alliance as one of the support contractors, and as you read in the book she helped supply the food for the shuttle and the station.

You also might be interested to know that Amy was interviewed for the astronaut program in January. For this selection process they had around 6,000 people who applied and they narrowed it down to about 400 that they deemed most qualified, and from that 400 they brought in 120, and she made that cut.

They will further reduce the number down to about 50 that will be brought back in for a second round of additional interviews and screenings, mostly some fairly heavy medical testing, and then from that they will select about 10 or so in the middle of the year. So we are extremely excited for her and keeping our fingers crossed.

UT: You write in detail about the two shuttle accidents. How difficult were those two periods of time – both personally and for everyone in the astronaut office?

JR: It was a tremendous loss. The astronaut office is relatively small. At the time of those losses, we were in the neighborhood of about 100 people total, and you get to know folks pretty well. To have your friends doing what we all enjoyed and seeing them be lost and then learning that probably, had we been smarter or more diligent, we as an agency could have prevented both of those accidents. That is very hurtful.

You go through a lot of soul searching, especially after the Challenger accident when we were still very early in the shuttle program to lose a vehicle and friends that way. My family was still quite young and it makes you really do some soul searching about whether or not you should continue to do that and put your life and therefore your family at risk. We talked about it quite a bit as a family and fortunately we all agreed that it would be letting our friends down if we decided to pull out and go do something else.

UT: You mentioned this earlier, and you don’t mince words in the book about your disappointment with the direction NASA is going. Have your thoughts changed any about the SLS?

JR: No, I still think that the agency is wandering in the forest. Most of the direction that we are getting from Congress is the direction that reinstituted the SLS and is pushing Orion forward. The administration is really pushing the commercial space aspect, and it still makes me very nervous that the commercial space guys may not pan out. It makes me nervous that NASA won’t have more control and insight on what is going on with the vehicles, from both a safety and operational perspective. It makes me nervous that we are planning to rely up on them solely to get to and from low Earth orbit, when in fact if they have an accident either with one of our crews or theirs, it could precipitate a lawsuit, which might put them into bankruptcy. Where would we be then?

So there are lots of reasons why I don’t think this is the right answer. I totally agree with commercial space if they want to go spend their own nickel and go do things, that is fine. As a government agency I think we should provide all the help and assistance that we can, but at the same time I don’t think we should be diverting resources of NASA’s programs to be paying for theirs. And that is what we are doing right now.

If we had not stopped the Constellation program, we would be in the process of getting ready to go launch an Orion right now. So what we are doing is delaying progress for the nation and what is going to happen in respect to commercial space is not at all certain. I frankly do not see any business model that would keep any of those commercial systems operating without a great underwriting and usage by NASA. And so I don’t see the logic in what is going on.

UT: Your faith is obviously very important to you, and I recall the one line you wrote, that you find it impossible to believe that everything you saw from space was created without God. In some circles, it seems to be that it is either science or religion that the two are hard to mix. But you obviously have no problem mixing the two in your life.

JR: Absolutely. I have had no problems along those lines whatsoever. I think the problems come when people try to read too literally passages in the Bible, and to not to just accept God on faith. So, somehow I think people try to limit God by reading an exact passage in the Bible, in a certain kind of Bible, when in fact the passage would read quite differently depending on what kind of Bible you are reading.

UT: Is there anything else that you feel is important for people to know about your book or your experiences in general?

JR: I hope people will read the book and enjoy it, number one! Secondly I hope they will get a better understanding of what it takes to make a spaceflight happen. But probably the most important thing is that I hope that it might help young adults and school age children interested in science and engineering. But the main emphasis of the book is to set goals for yourself, study hard, work hard and don’t give up too easily.

UT: Jerry, its been an honor to talk with you! Thank you very much.

JR: I’ve enjoyed it, thank you!

From One Laurel to Another: a Letter from Columbia

STS-107 Mission Specialist Laurel B. Clark (NASA)

On this Day of Remembrance, February 1, 2013, NASA will mark the 10th anniversary of the STS-107 Columbia accident with a wreath-laying ceremony at the astronaut memorial in Arlington National Cemetery, paying tribute to the lost crews of Columbia, Challenger and Apollo 1, as well as other space explorers and NASA colleagues who have passed on. Most of us have our own personal memories of the tragic events that took the lives of these brave few who risked everything in the name of exploration, knowledge, and discovery, and I’ve agreed to share one person’s connection to the Columbia crew.

Laurel Nendza, a fellow space blogger over on that social media site that begins with F and rhymes with “acebook” has a particular connection with STS-107 Mission Specialist Laurel B. Clark… if only that they both love space and share the same first name. Still, it’s enough to hang one’s heart on, and Laurel (the blogger) recently posted a particularly touching note that was sent by Laurel (the astronaut) to her family just before Columbia headed back on its ill-fated return trip home. Here’s Laurel’s (and Laurel’s) story:

On February 1, 2003, the seven [STS-107] crew members were lost with the Space Shuttle Columbia over North Texas during the shuttle’s re-entry. They were brave men and women who gave their lives for space exploration.

One member has always stood out to me. Her name was Laurel Clark. She would probably agree that growing up there were never any other Laurels around. She may at one time hated her name like I did, only to realize she was actually cool and unique because she was the only one around with that name. But Laurel is not just a name, it’s a personality trait. I know a handful of Laurels (mostly from Facebook) and we all seem to have the same things in common. Most of us always have had deep compassion for animals, the Earth, and the sky above us. Laurel Clark was no different.

What was different about Laurel Clark is that she was just a handful of people on Earth, EVER, who actually achieved what we all dream. She was an astronaut and got to go to outer space. She had the privilege (that she worked very hard to get) to witness our pale blue dot from above as well as breathtaking auroras, lightning, and the Sun and Moon rising.

Before she departed to her last shuttle flight home she sent an email to her family and close friends. She told them of every incredible, awe-inspiring moment she had been a part of. She and the other 6 members who perished in the Columbia tragedy are true heroes and inspirations to all who came after her. They are my inspiration. My dream is to also be able to see my beautiful planet from above, and to see the stars shine bright in all their glory.

She was the first Laurel in space, who knows? Maybe one day I will be the next?

Rest in peace all the brave crew of the Shuttle Columbia.

Below is Laurel Clark’s last message to her loved ones on Earth:

“Hello from above our magnificent planet Earth. The perspective is truly awe-inspiring. This is a terrific mission and we are very busy doing science round the clock. Just getting a moment to type e-mail is precious so this will be short, and distributed to many who I know and love.

I have seen some incredible sights: lightning spreading over the Pacific, the Aurora Australis lighting up the entire visible horizon with the cityglow of Australia below, the crescent moon setting over the limb of the Earth, the vast plains of Africa and the dunes on Cape Horn, rivers breaking through tall mountain passes, the scars of humanity, the continuous line of life extending from North America, through Central America and into South America, a crescent moon setting over the limb of our blue planet. Mount Fuji looks life a small bump from up here, but it does stand out as a very distinct landmark.

Magically, the very first day we flew over Lake Michigan and I saw Wind Point (Wisconsin) clearly. Haven’t been so lucky since. Every orbit we go over a slightly different part of the Earth. Of course, much of the time I’m working back in Spacehab and don’t see any of it. Whenever I do get to look out, it is glorious. Even the stars have a special brightness.

I have seen my ‘friend’ Orion several times. Taking photos of the earth is a real challenge, but a steep learning curve. I think I have finally gotten some beautiful shots the last 2 days. Keeping my fingers crossed that they’re in sharp focus.

My near vision has gotten a little worse up here so you may have seen pics/video of me wearing glasses. I feel blessed to be here representing our country and carrying out the research of scientists around the world. All of the experiments have accomplished most of their goals despite the inevitable hiccups that occur when such a complicated undertaking is undertaken. Some experiments have even done extra science. A few are finished and one is just getting started today.

The food is great and I am feeling very comfortable in this new, totally different environment. It still takes a while to eat as gravity doesn’t help pull food down your oesophagus. It is also a constant challenge to stay adequately hydrated. Since our body fluids are shifted toward our heads our sense of thirst is almost non-existent.

Thanks to many of you who have supported me and my adventures throughout the years. This was definitely one to beat all. I hope you could feel the positive energy that beamed to the whole planet as we glided over our shared planet.

Love to all, Laurel.”

At 10 a.m. EST on Feb. 1, NASA TV will provide live coverage of a wreath-laying ceremony at the Space Mirror Memorial located in the Kennedy Space Center Visitor Complex in Florida. Flags across the agency will be flown at half-staff memory of the Columbia crew and all who have lost their lives in dedication of space exploration.

Historic First Use of Drill on Mars Set for Jan. 31 – Curiosity’s Sol 174

The long awaited and history making first use of a drill on Mars is set to happen on Thursday, Jan. 31, 2013, or Sol 174, by NASA’s Curiosity Mars Science Lab (MSL) rover, if all goes well, according to science team member Ken Herkenhoff of the USGS.

Curiosity’s first drilling operation entails hammering a test hole into a flat rock at the location where the rover is currently parked at a scientifically interesting outcrop of rocks with veined minerals called ‘John Klein’. See our mosaics above & below illustrating Curiosity’s current location.

“Drill tailings will not be collected during this test, which will use only the percussion (not rotation) drilling mode,” says Herkenhoff.

Curiosity is an incredibly complex robot that the team is still learning to operate. So the plan could change at a moment’s notice.

The actual delivery of drill tailings to Curiosity’s CheMin and SAM analytical labs is still at least several days or more away and must await a review of results from the test drill hole and further drilling tests.

“We are proceeding with caution in the approach to Curiosity’s first drilling,” said Daniel Limonadi, the lead systems engineer for Curiosity’s surface sampling and science system at NASA’s Jet Propulsion Laboratory (JPL). “This is challenging. It will be the first time any robot has drilled into a rock to collect a sample on Mars.”

On Sol 166, Curiosity drove about 3.5 meters to reach the John Klein outcrop that the team chose as the 1st drilling site. The car sized rover is investigating a shallow depression known as ‘Yellowknife Bay’ – where she has found widespread evidence for repeated episodes of the ancient flow of liquid water near her landing site inside Gale Crater on Mars.

In anticipation of Thursday’s planned drilling operation, the rover just carried out a series of four ‘pre-load’ tests on Monday (Jan. 27), whereby the rover placed the drill bit onto Martian surface targets at the John Klein outcrop and pressed down on the drill with the robotic arm. Engineers then checked the data to see whether the force applied matched predictions.

“The arm was left pressed against one of them overnight, to see how the pressure changed with temperature,’ says Herkenhoff.

Because huge temperature swings occur on Mars every day (over 65 C or 115 F), the team needs to determine whether there is any chance of excessive stress on the arm while it is pressing the drill down onto the Martian surface. The daily temperature variations can cause rover systems like the arm, chassis and mobility system to expand and contact by about a tenth of an inch (about 2.4 millimeters), a little more than the thickness of a U.S. quarter-dollar coin.

“We don’t plan on leaving the drill in a rock overnight once we start drilling, but in case that happens, it is important to know what to expect in terms of stress on the hardware,” said Limonadi. “This test is done at lower pre-load values than we plan to use during drilling, to let us learn about the temperature effects without putting the hardware at risk.”

The high resolution MAHLI microscopic imager on the arm turret will take close-up before and after images of the outcrop target to assess the success of the drilling operation.

On Sol 175, another significant activity is planned whereby one of the ‘blank” organic check samples brought from Earth will be delivered to the SAM instrument for analysis as a way to check for any traces of terrestrial contamination of organic molecules and whether the sample handing system was successfully cleansed earlier in the mission at the Rocknest windblown sand ripple.

Meanwhile on the opposite side of Mars, NASA’s Opportunity rover starts Year 10 investigating never before touched phyllosilicate clay minerals that formed eons ago in flowing liquid water at Endeavour crater – detailed here.

Stay tuned for exciting results from NASA’s Martian sisters.

The Cost of Exploring Space: Film vs. Reality

We all know that space exploration, while certainly not the largest expenditure of most countries, doesn’t come cheap. But neither do big-budget science fiction films, either. Special effects, sets, special effects, popular acting talent… special effects… those all come with hefty price tags that make sci-fi and fantasy films costly ventures — although bigger definitely isn’t always better. If you were to compare the price of real space exploration missions (which provide actual information) to the costs of movies about space exploration (which provide “only” entertainment) what would you expect to find?

This infographic does just that:

“Prometheus’ movie budget would be enough to keep the search for real aliens going for another 52 years.”

Wow. (Maybe they should have just written a check to SETI.)

How a Good Narrator Can Mean Life or Death on Mars

Stranded on an alien planet, ejected from your burning ship and with only minutes of breathable air left, your chances of survival look slim indeed. And with — something — tearing holes in your suit, you’ll likely be dead before you know it.

That is, of course, unless you have a good narrator.

“Voice Over,” a short film directed by Martin Rosete, puts you in this and a couple other similarly precarious situations, each seemingly bleaker than the last. Through it all a narration by Feodor Atkine underscores the hopelessness (in French, with subtitles) until the final reveal, which… well, I won’t spoil it for you. All I’ll say is it’s well worth 9 minutes of your time.

Watch the video below.

(Quick warning: a couple of parts are slightly graphic.)

I must say, I couldn’t help but feel like I was watching a film version of a Choose Your Own Adventure book.

Opportunity Rover Starts Year 10 on Mars with Remarkable Science Discoveries

9 Years ago, NASA’s pair of identical twin sister rovers – christened Spirit & Opportunity- bounced to daunting airbag-cushioned landings on opposite sides of the Red Planet for what was supposed to be merely 90 day missions, or maybe a little bit longer scientists hoped.

Today, Opportunity celebrates a truly unfathomable achievement, starting Year 10 on Mars since she rolled to a bumpy stop on January 24, 2004 inside tiny Eagle crater. And she’s now at a super sweet spot for science (see our photo mosaic above) loaded with clays and veined minerals and making the most remarkable findings yet about the planets watery past – thus building upon a long string of previously unthinkable discoveries due to her totally unforeseen longevity.

“Regarding achieving nine years, I never thought we’d achieve nine months!” Principal Investigator Prof. Steve Squyres of Cornell University told Universe Today for this article commemorating Opportunity’s 9th anniversary.

Opportunity reached 3200 Sols, or Martian days, and counting , by her 9th birthday. She is now 108 months into the 3 month primary mission – that’s 36 times longer than the 3 month “warranty.”

“Every sol is a gift,” Squyres told me. He always refers to the rovers as our “Priceless assets on Mars”, that have to be taken good care of to wring out the maximum science data possible and for as long as humanly, or more aptly, robotically possible.

The resilient, solar powered Opportunity robot begins her 10th year roving around beautifully Earth-like Martian terrain where where she proved that potentially life sustaining liquid water once flowed billions of years ago when the planet was warmer and wetter.

Opportunity is healthy and has driven over 22 miles (35 kilometers )- marking the first overland expedition on another planet. See our photo mosaics and route map by Ken Kremer and Marco Di Lorenzo.

She is now working at the inboard edge of “Cape York” – a hilly segment of the eroded rim of 14 mile (22 km) wide Endeavour Crater, featuring terrain with older rocks than previously inspected and unlike anything studied before. It’s a place no one ever dared dream of reaching prior to launch in the summer of 2003 and landing on the Meridiani Planum region of Mars.

“It’s like a whole new mission since we arrived at Cape York,” says Squyres.

Today Opportunity is poised for breakthrough science at deposits of phyllosilicates – clay minerals which stem from an earlier epoch when liquid water flowed on Mars eons ago and perhaps may have been more favorable to sustaining microbial life because they form in more neutral pH water. Endeavour Crater is more than 3 Billion years old.

I asked Squyres to discuss the discovery of the phyllosilicates – which have never before been analyzed up close on the Martian surface and are actually a main target of NASA’s new Curiosity rover at Gale Crater.

“We have found the phyllosilicates at Cape York: they’re in the Whitewater Lake materials,” Squyres explained. Spectral data collected from Mars orbit by the CRISM spectrometer aboard NASA’s MRO circling spacecraft allowed the researchers to direct Opportunity to this exact spot.

“Whitewater Lake” is an area of bright local outcrops currently being investigated and providing information about a different and apparently less acidic environment compared to other areas and craters visited earlier in the mission – and potentially more conducive to life.

Opportunity also discovered more mineral veins at “Whitewater Lake”, in addition to those hydrated mineral veins discovered earlier at Cape York at a spot named “Homestake” – see our mosaic below.

“We have investigated the veins in these materials, and we have determined that they are calcium sulfate,” Squyres confirmed to me.

How do the new mineral veins compare to those at ‘Homestake’ and those just found by Curiosity at Yellowknife Bay inside Gale crater? I asked Sqyures.

“Much narrower, and possibly older,” he said compared to the Homestake calcium sulfate veins .

“It’s too early to say how they compare to the veins at Gale, though.”

The local area at “Cape York” is called “Matijevic Hill” – in honor of a recently deceased team member who played a key role on NASA’s Mars rovers.

The rover has already spent a few months at “Matijevic Hill” on a ‘walk about’ scouting survey and also found concretions dubbed “newberries” that are different from the “blueberry” concretions found earlier in the mission.

How widespread are the phyllosilicates ?

“Matijevic Hill is the only exposure of phyllosilicates we know of at Cape York, so in order to find more we’re going to have to go elsewhere,” Squyres replied. “We haven’t figured out what the “newberries” are yet, but attempting to do that will be our next task.”

It is likely to take many more weeks and even months to “figure out” what this all means for science.

Therefore, no one should expect the robot to move much in the near future. Since the rover made landfall at the western rim of Endeavour crater at Spirit Point in August 2011, she has been circling around Cape York ever since.

What is the next destination for Opportunity?

“Once we’re done at Cape York, our next destination will be Solander Point [to the south],” Squyres confirmed. It’s the next rim segment south of Cape York (see map).

Eventually, if Opportunity continues to function and survives the next Martian winter, she may be directed several miles even further south, along the crater rim to a spot called Cape Tribulation – because it also harbors caches of phyllosilicate clay minerals. But there is no telling when that might be.

“One step at a time,” said Squyres as always. He is not making any guesses or predictions. The mission is totally discovery driven.

Well after so many great science discoveries over the past 9 years, I asked Squyres to describe the context and significance of the phyllosilicates discovery?

“Impossible to say, I’m afraid… we’re still figuring this place out; I can’t put it in context yet,” Squyres concluded.

Thus, there is still so much more bountiful science research still to be done by Opportunity – and nobody is making any forecasts on how long she might yet survive.

So just keep praying to the Martian weather gods for occasional winds and “dust devils” to clean off those life giving solar panels – and to the US Congress to provide the essential funding.

Curiosity’s Robotic Arm Camera Snaps 1st Night Images

Curiosity’s high resolution robotic arm camera has just snapped the 1st set of night time images of a Martian rock of the now 5 1/2 month long mission – using illumination from ultraviolet and white light emitting LED’s. See the images above and below.

The Mars Hand Lens Imager (MAHLI) camera is located on the tool turret at the end of Curiosity’s 7 foot (2.1 m) long robotic arm.

MAHLI took the close-up images of a rock target named “Sayunei” on Jan. 22 (Sol 165), located near the front-left wheel after the rover had driven over and scuffed the area to break up rocks in an effort to try and expose fresh material, free of obscuring dust.

“Sayunei” is at the site of the “John Klein” outcrop in “Yellowknife Bay” where the team hopes to commence the 1st rock drilling operations here in the coming days. Curiosity drove a few meters several sols ago to reach “John Klein”.

See below our Sol 157 mosaic showing the “John Klein” outcrop – where the rover snapped these night images of “Sayunei”.

“The purpose of acquiring observations under ultraviolet illumination was to look for fluorescent minerals,” said MAHLI Principal Investigator Ken Edgett of Malin Space Science Systems, San Diego. “These data just arrived this morning. The science team is still assessing the observations. If something looked green, yellow, orange or red under the ultraviolet illumination, that’d be a more clear-cut indicator of fluorescence.”

Analysis is still in progress to determine whether fluorescent minerals are present. Certain classes of organic compounds are also fluorescent.

MAHLI is an adjustable focus camera that works over a wide range. It can focus on targets just a few centimeters away or on distant objects like Mount Sharp, over 6 miles (10 km) away.

The LED’s surround the MAHLI lens.

Curiosity has discovered widespread evidence for the ancient flow of liquid water at “Yellowknife Bay” in the form of water bearing mineral veins, cross-bedded layering, nodules and spherical sedimentary concretions.

The Ocean is a lot Like Outer Space

A view of the Bathyscaphe Trieste in 1959. (U.S. NHHC)

Just about any space mission these days requires water training. Think of the countless hours astronauts spend in the Neutral Buoyancy Laboratory at the Johnson Space Center, practicing the steps to do spacewalks. Then there are the crews that actually live in the ocean for days at a time on NASA’s NEEMO missions.

Long before these “aquanauts” added flippers to their list of equipment, however, the U.S. Navy was busy exploring the depths of the ocean. Today – Jan. 23 – marks the anniversary of the Bathyscaphe Trieste’s descent to the bottom of the ocean in 1960. This was the first time a vessel, manned or unmanned, had reached the deepest known point of the Earth’s oceans, the Mariana Trench.

Trieste was at first operated by the French Navy, which operated it for several years in the Mediterranean Sea, but the US Navy purchased the Trieste in 1958.

Although two men took the ride down, all accounts say that it was an isolating experience. Jacques Piccard – well-known today for his exploration of the oceans – and US Navy Lieutenant Don Walsh descended about 11 kilometers (7 miles) to the bottom.

Fighting with poor communications and high pressure – which cracked a window at 30,000 feet below the surface – the crew made their way to ocean floor. They worked in a tiny sphere only 2 meters (6.5 feet) wide, and according to the University of Delaware, the interior reached frigid temperatures of 7 degrees Celsius (45 degrees Fahrenheit) during their successful descent and return.

Spaceflight and deep-ocean diving share many similarities, as this mission demonstrated. The early days of the space program had communications blackouts as spaceships flew between stations; this proved to be a near-disaster for the Gemini 8 crew in 1966 when their spacecraft spun out of control during a period with no voice connection to the ground.

Also, sustaining life is no less challenging in the water as it is in space. Humans require oxygen, pressure and a comfortable environment where they work. Crews in space have faced serious problems with all of these matters before – Mir suffered a partial depressurization in 1997, and the early days of the Skylab space station were rather hot until the astronauts could deploy a sunshade.

Walsh was not available for an interview with Universe Today due to travel, but in a 2012 BBC interview he noted that he had reserved confidence that they would make it to the bottom.

“I knew the machine well enough, at that point, to know that theoretically, it could be done,” Walsh recalled.

The mens’ feat would go unrepeated for decades, until in 2012 Hollywood director James Cameron made the descent again – alone, although certainly equipped with more modern technology. For comparison, only one American has flown solo in space since the 1960s; in 2004, Mike Melvill piloted SpaceShipOne into suborbital space twice as part of the Ansari X-Prize win.
