This Rover Could Hunt For Lunar Water And Oxygen In 2018

In 2018, NASA plans to go prospecting at the moon’s south pole with a rover — possibly, a version of the Canadian one in the picture above. The idea is to look for water and similar substances on the lunar surface, with an eye to learn more about living off the land, so to speak.

Launching anything into space is expensive, so if it’s possible to harvest raw materials off a moon or planetary surface, this could make things a bit cheaper. Specifically, NASA is interested in oxygen, water, silicon and light metals such as aluminum and titanium in the moon’s soil or regolith. (This process is called in situ resource utilization capability.)

“The mission, currently planned to launch in early 2018, will demonstrate extraction of oxygen from lunar regolith to validate in situ resource utilization capability,” said NASA spokesperson Trent Perrotto in an e-mail to Universe Today.

“An essential element of this mission is the ability to travel significant distances on the surface to better understand water distribution in the lunar regolith.”

So that’s the background. Where does the rover stand in this? It would carry a payload called RESOLVE (the acronym stands for Regolith & Environment Science, and Oxygen & Lunar Volatile Extraction.) And the rover has already been through some field tests to see how well it performs in environments (fairly) similar to the moon.

In 2009, for example, the Canadian Space Agency did a summer field study with NASA, Perrotto said. “The Canadian rover carried the RESOLVE payload during field tests. The tests helped NASA better understand the requirements of a volatiles-sensing payload, and helped CSA understand tele-operation and rough terrain exploration,” he wrote.

At the time, NASA was working to get the payload ready for flight status in 2011, but the mission design has changed since then. The current design (called Resource Prospector Mission) would have RESOLVE, a Canadian Space Agency rover and drill, and a lander. NASA is now looking for somebody to work on the lander.

“A request for information was released in July to identify industry interest in a partnership to develop the lander; and an announcement of opportunity is anticipated to be released in early December,” Perrotto wrote.

This mission design is not a guarantee yet. For one thing, NASA is looking at rover alternatives and possibly getting a drill from a United States source instead. It also would depend on funding and agency priorities in the next few years. That said, however, the mission concept is proceeding right now.

In September, Perrotto added, the CSA and NASA did “initial RESOLVE thermal and vacuum testing in September, including a test in [a] regolith-filled vacuum chamber at the NASA Glenn Research Center (GRC) at lunar temperatures and pressures.” RPM passed a mission concept review on Sept. 17 and is in the midst of a preliminary design review that would conclude in fall 2014.

NASA’s Advanced Exploration Systems office has started to look at alternative options to understand “technical constraints by the mission and to assess affordability,” Perrotto added. Meanwhile, the payload team is assessing and looking to reduce risks, while the CSA and NASA are working to “refine technologies for ISRU.”

Representatives from the Canadian team also discussed the rover concept at the Canadian Space Society annual conference in Ottawa, Canada earlier this month. More information on RESOLVE is available on the CSA website; last year, the agency unveiled several rovers it developed for moon and Mars exploration.

‘I Didn’t Think He Would Drown’: Spacewalking Crewmember on Spacesuit Leak

Safely back on Earth on Sept. 10, astronaut Chris Cassidy happily chatters about his daily trips to the gym — “I feel real solid with my walking”, he says — and cracks one-liners during one of a series of media interviews on Thursday.

“It was such a treat being up there with [Chris] Hadfield, and I think I need to get credit for filming some of those videos,” joked Cassidy in a phone interview from Houston with Universe Today. His favorite video with Canada’s Expedition 35 commander? A remake of David Bowie’s Space Oddity that got props from Bowie himself.

Cassidy’s half-year voyage in space was full of these light moments, such as his decision to shave his head in homage to his bald crewmate, Luca Parmitano, who arrived on the International Space Station as a part of Expedition 36 on May 29. Weeks later, however, the men’s mood turned serious during a July 16 spacewalk; Parmitano reported water pooling at the back of his head.

“I was watching out when we were face to face outside,” Cassidy said. “Once it got onto his eyebrow hair area, it whipped across the top of his forehead and then sort of slid around his eyeballs. It migrates from hair to hair, and the little wispy hairs around your eyes, kind of, and then it travelled towards his eyelids and eyelashes. That was the scary part.”

Cassidy is a former Navy SEAL who passed, first try, the grueling “hell week” all recruits go through. In 5.5 days, SEAL trainees get just four hours of rack time while having to move for up to 200 miles. A veteran of shuttle mission STS-127, Cassidy also accumulated more than 18 hours of spacewalking experience across three excursions. All of his knowledge was brought to bear as he watched the water travelling across Parmitano’s head.

“From my experience in the military, I know bad things don’t get better fast, but they get worse fast. I wanted to get as quickly to the airlock as we could,” Cassidy said. NASA prudently ended the spacewalk and told Parmitano to head back to the hatch. Cassidy quickly did a cleanup at the work site and followed Parmitano.

“When we left each other at the work site and we had to go our separate ways back, at first I wasn’t too concerned,” Cassidy said. “And then when we left each other, the sun set. It was dark. His comm was going in and out and I could tell from his voice he was getting less and less comfortable … He didn’t have a whole lot of EVA experience, and it was nighttime, which is significant. It was pitch dark. You just have to know your way back, and he couldn’t see that well.”

Back in the hatch, Cassidy and Parmitano communicated through hand squeezes as the water was soaking Parmitano’s communications system. Cassidy carefully watched Parmitano’s mouth to see if the water was getting near there.

“I didn’t think he would drown, to be honest … but if it got close to his mouth I was going to immediately open the valve that equalizes pressure [inside the hatch.]” Cassidy added that usually, NASA goes slow during repressurization for ear safety and some technical reasons, but in this case he was prepared to flood the compartment if necessary. But it wasn’t. The rest of the crew then opened the hatch and got Parmitano out of his spacesuit as quickly as they could.

“Just from a human interest point of view, it was a lot of water,” Cassidy said. “When you try to describe an amount of water it’s difficult to put it in terms that people get it. But it was definitely more than a softball or two softballs of water inside the helmet.”

You can read Parmitano’s blogged account of the spacewalk here. The astronaut is currently unavailable for interviews while he is in orbit, the European Space Agency told Universe Today. NASA is still investigating the cause — the agency, in fact, also has a parallel investigation to look at spacewalk safety procedures in general. Cassidy attempted to change a filter and do other repairs in orbit, but the leak still happened, as these videos show. More detailed analysis will happen when the spacesuit goes back to Earth on a future SpaceX Dragon cargo flight, Cassidy said.

Cassidy also performed an emergency spacewalk in May when a coolant leak was discovered on the station itself as Hadfield’s Expedition 35 crew was set to return home. In just days — a typical spacewalk takes at least months to plan — NASA swiftly implemented a successful fix. Cassidy said his work was the easiest bit of all. “All I had to do was go out there and change the pump,” he said.

Despite the mishaps, however, science productivity on the station has reached a high when compared to maintenance activities. Expedition 35 reportedly had the most productive science mission to date, and Cassidy said Expedition 36 will likely show similar results. “We had a real nice successful six month stretch there where things were just working, and that allowed us to do a lot of science,” Cassidy said. One experiment involved playing with rovers.

Cassidy, Parmitano and Karen Nyberg each took turns operating the K10 rover prototype, a NASA Ames Research Center project. The goal is to simulate how astronauts could control a rover on an asteroid, the moon or Mars rather than heading down to the surface themselves.

“That was really cool to know we were on the space station, flying around the planet, with this actual real thing in California moving around,” Cassidy said. “It was more testing of what user interfaces are most intuitive and most useful for this kind of application … and in my opinion they pretty much nailed it, it was so intuitive.”

Now back on Earth, Cassidy said he generally feels great from a health perspective. His first set of exercises came about an hour after landing. He was carried into a medical tent and asked to do a quick series: sit in a chair and then stand up for 10 seconds. Lie on the ground for about a minute, then try standing for three minutes.

“My legs got wobbly for fatigue. They weren’t used to holding that weight,” Cassidy said, but observed that he readjusted to Earth’s gravity quickly during his first day back, which was mainly spent flying from Kazakhstan back to Houston.

The new in-the-field experiments will be the first of a dataset on astronaut health, meant to provide more information ahead of the first one-year trip to the International Space Station.

This Company Wants To Send Robots Into Lunar Caves

Astrobotic's model rover explores a mine on Earth to train for lunar lava tunnels (Video screenshot)

Ever since (and most likely long before) the first tantalizing glimpses of a lunar lava tube and skylight were captured by Japan’s Kaguya spacecraft in 2009, scientists have been dreaming of ways to explore inside these geological treasures. Not only would they provide valuable information on the movement of ancient lunar lava flows, but they could also be great places for future human explorers to set up camp and be well-protected from dangerous solar and cosmic radiation.

But before human eyes will ever peer into the darkness of a lava tube on the Moon, robotic rovers will roll along their silent floors — at least, they will if Google Lunar XPRIZE competitor Astrobotic has anything to say about it.

Last month, engineer and Astrobotic CEO Dr. Red Whitttaker talked to NASA about why they want to explore a Moon cave and the history and progress of their project. Check it out below:


“Something so unique about the lava tubes is that they are the one destination that combines the trifecta of science, exploration, and resources.”

– Dr. William “Red” Whittaker, CEO Astrobotic Technology, Inc.

See this and more in-progress Moon plans from various research facilities on the Google Lunar XPRIZE Moon Roundup.

The international Google Lunar XPRIZE aims to create a new “Apollo” moment for a new generation by driving continuous lunar exploration with $40 million in incentive-based prizes. In order to win, a private company must land safely on the surface of the Moon, travel 500 meters above, below, or on the lunar surface, and send back two “Mooncasts” to Earth… all by Dec. 31, 2015.

Astrobotic Technology Inc. is a Pittsburgh-based company that delivers affordable space robotics technology and planetary missions. Spun out of Carnegie Mellon University’s Robotics Institute in 2008, Astrobotic is pioneering affordable planetary access that promises to spark a new era of exploration, science, tourism, resource utilization and mining.

Meet GROVER the Rover, Set For Greenland Exploration

How fast is Greenland’s ice sheet melting in response to climate change, and how is it recovering? A new NASA rover with the friendly name of GROVER (Greeland Rover and Goddard Remotely Operated Vehicle for Exploration and Research) is going to try to figure that out.

GROVER will rove across a small area of the massive ice sheet at a location called Summit Camp, which is a National Science Foundation outpost. On board it has ground-penetrating radar that is intended to figure out how the snow builds up in layers through time.

“Robots like GROVER will give us a new tool for glaciology studies,” stated Lora Koenig, a glaciologist at Goddard and science advisor on the project.

The student-designed project came to be during development phases in 2010 and 2011, principally at Boise State University in Idaho. At six feet tall, it’s way more massive than its Sesame Street namesake: it tips the scale at 800 pounds, including solar panels, and has two snowmobile tracks built in to move around.

“GROVER is just like a spacecraft but it has to operate on the ground,” stated Michael Comberiate, a retired NASA engineer and manager of Goddard’s Engineering Boot Camp.

“It has to survive unattended for months in a hostile environment, with just a few commands to interrogate it and find out its status and give it some directions for how to accommodate situations it finds itself in.”

Studies began on May 3 and will continue through June 8.

Curiosity Once Again in Safe Mode – If Only Briefly

Not even two and a half weeks after a memory glitch that sent NASA’s Curiosity rover into a safe mode on Feb. 27, the robotic Mars explorer once again went into standby status as the result of a software discrepancy — although mission engineers diagnosed the new problem quickly and anticipate having the rover out of safe mode in a couple of days.

“This is a very straightforward matter to deal with,” said Richard Cook, project manager for Curiosity at Jet Propulsion Laboratory in Pasadena. “We can just delete that file, which we don’t need anymore, and we know how to keep this from occurring in the future.”

Via a JPL press release, issued March 18:

“Curiosity initiated this automated fault-protection action, entering ‘safe mode’ at about 8 p.m. PDT (11 p.m. EDT) on March 16, while operating on the B-side computer, one of its two main computers that are redundant to each other. It did not switch to the A-side computer, which was restored last week and is available as a back-up if needed. The rover is stable, healthy and in communication with engineers.

“The safe-mode entry was triggered when a command file failed a size-check by the rover’s protective software. Engineers diagnosed a software bug that appended an unrelated file to the file being checked, causing the size mismatch.”

 The rover is stable, healthy and in communication with engineers.

– NASA’s Jet Propulsion Laboratory

Once Curiosity is back online its investigation into the watery history of Gale crater will resume, but another hiatus — this one planned — will commence on April 4, when Mars will begin passing behind the Sun from Earth’s perspective. Mission engineers will refrain from sending commands to the rover during a four-week period to avoid data corruption from solar interference.

Keep up with the latest news from the MSL mission here.

Then again, there’s a certain personality on Twitter who claims a slightly different reason for these recent setbacks…

Sarcastic Rover

 

First Color Image of Curiosity’s Tracks from Orbit

As Curiosity prepares for the historic first drilling operation on Mars, the HiRISE camera aboard the Mars Reconnaissance Orbiter captured an image of it from 271 km (169 miles) up, along with twin lines of tracks and the blast marks from the dramatic rocket-powered descent back on August 6 (UTC).

The image here was acquired on Jan. 13, Sol 157 of the MSL mission, as part of a dual HiRISE/CRISM observation of the landing site. According to The University of Arizona’s HiRISE site it’s the first time the rover’s tracks have been imaged in color.

Her original landing site can be seen at the right edge. (Wait… did I just say “her?”)

The pair of bright white spots in the HiRISE image show the area immediately below where sky crane’s rockets were pointed. Those areas were “blasted clean” and therefore show brightest. The larger dark scour zone is dark because the fine dust has been blown away from the area leaving darker materials.

– Ross A. Beyer, UofA HiRISE team

Curiosity can be seen as she (yes, it was confirmed today during ScienceOnline2013 that the rover — like all exploration vehicles — is a girl) was preparing for drilling into a rock outcrop called John Klein within the “Yellowknife” region in Gale Crater. Drilling is expected to begin today, Jan. 31.

NASA Reveals Plans for New Mars Rover

Sequels are all the rage these days… even for NASA, apparently.

At the American Geophysical Union 2012 convention in San Francisco today, NASA’s associate administrator for science John Grunsfeld revealed the agency’s plans for another Mars mission. Slated to land in 2020, it will be a rover based on the same design as Mars Science Laboratory. Estimated cost of the mission was announced to be $1.5 billion.

This news brought mixed reactions from many of those in attendance as well as followers online, as while more exploration of the Red Planet is certainly an exciting concept, we have all heard — and seen — countless tales of budget cuts and funding problems throughout NASA over recent years, and many proposed missions and collaborations have had to be shelved or cut short due to lack of funds (remember ExoMars?) Even though the budget for this mission is supposedly “not being taken from other areas,” it’s clearly not going to them either. It will be interesting to see how this plays out across the agency.

The full press release from NASA can be seen below:

(Via NASA)

Building on the success of Curiosity’s Red Planet landing, NASA has announced plans for a robust multi-year Mars program, including a new robotic science rover set to launch in 2020. This announcement affirms the agency’s commitment to a bold exploration program that meets our nation’s scientific and human exploration objectives.

“The Obama administration is committed to a robust Mars exploration program,” NASA Administrator Charles Bolden said. “With this next mission, we’re ensuring America remains the world leader in the exploration of the Red Planet, while taking another significant step toward sending humans there in the 2030s.”

The planned portfolio includes the Curiosity and Opportunity rovers; two NASA spacecraft and contributions to one European spacecraft currently orbiting Mars; the 2013 launch of the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter to study the Martian upper atmosphere; the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission, which will take the first look into the deep interior of Mars; and participation in ESA’s 2016 and 2018 ExoMars missions, including providing “Electra” telecommunication radios to ESA’s 2016 mission and a critical element of the premier astrobiology instrument on the 2018 ExoMars rover.

The plan to design and build a new Mars robotic science rover with a launch in 2020 comes only months after the agency announced InSight, which will launch in 2016, bringing a total of seven NASA missions operating or being planned to study and explore our Earth-like neighbor.

The 2020 mission will constitute another step toward being responsive to high-priority science goals and the president’s challenge of sending humans to Mars orbit in the 2030s.

The future rover development and design will be based on the Mars Science Laboratory (MSL) architecture that successfully carried the Curiosity rover to the Martian surface this summer. This will ensure mission costs and risks are as low as possible, while still delivering a highly capable rover with a proven landing system. The mission will constitute a vital component of a broad portfolio of Mars exploration missions in development for the coming decade.

The mission will advance the science priorities of the National Research Council’s 2011 Planetary Science Decadal Survey and responds to the findings of the Mars Program Planning Group established earlier this year to assist NASA in restructuring its Mars Exploration Program.

“The challenge to restructure the Mars Exploration Program has turned from the seven minutes of terror for the Curiosity landing to the start of seven years of innovation,” Grunsfeld said. “This mission concept fits within current and projected Mars exploration budget, builds on the exciting discoveries of Curiosity, and takes advantage of a favorable launch opportunity.”

The specific payload and science instruments for the 2020 mission will be openly competed, following the Science Mission Directorate’s established processes for instrument selection. This process will begin with the establishment of a science definition team that will be tasked to outline the scientific objectives for the mission.

This mission fits within the five-year budget plan in the president’s Fiscal Year 2013 budget request, and is contingent on future appropriations.

Plans also will include opportunities for infusing new capabilities developed through investments by NASA’s Space Technology Program, Human Exploration and Operations Mission Directorate, and contributions from international partners.

NASA and John Grunsfeld will be hosting a follow-up press conference later today at AGU, which will be streamed live online at 7 p.m. EST/4 p.m. PST. Stay tuned for more information.

 

Curiosity’s Laser Leaves Its Mark

Before-and-after images from Curiosity’s ChemCam  micro-imager show holes left by its million-watt laser (NASA/JPL-Caltech/LANL/CNES/IRAP/LPGN/CNRS)

PEWPEWPEWPEWPEW! Curiosity’s head-mounted ChemCam did a little target practice on August 25, blasting millimeter-sized holes in a soil sample named “Beechey” in order to acquire spectrographic data from the resulting plasma glow. The neat line of holes is called a five-by-one raster, and was made from a distance of about 11.5 feet (3.5 meters).

Sorry Obi-Wan, but Curiosity’s blaster is neither clumsy nor random!

Mounted to Curiosity’s “head”, just above its Mastcam camera “eyes”, ChemCam combines a powerful laser with a telescope and spectrometer that can analyze the light emitted by zapped materials, thereby determining with unprecedented precision what Mars is really made of.

Read: Take a Look Through Curiosity’s ChemCam

For five billionths of a second the laser focuses a million watts of energy onto a specific point. Each of the 5 holes seen on Beechey are the result of 50 laser hits. 2 to 4 millimeters in diameter, the holes are much larger than the laser point itself, which is only .43 millimeters wide at that distance.

“ChemCam is designed to look for lighter elements such as carbon, nitrogen, and oxygen, all of which are crucial for life,” said Roger Wiens, principal investigator of the ChemCam team. “The system can provide immediate, unambiguous detection of water from frost or other sources on the surface as well as carbon – a basic building block of life as well as a possible byproduct of life. This makes the ChemCam a vital component of Curiosity’s mission.”

Take a Look Through Curiosity’s ChemCam

This (adjusted) image was taken by ChemCam’s Remote Micro-Imager on Sol 15 (NASA/JPL-Caltech/LANL)

While Curiosity has been getting a good look around its landing spot on Mars, taking in the sights and sending back some impressive views of distant hills and Gale Crater’s enormous central peak, it’s also been peering very closely at some tiny targets just meters away — with its head-mounted, laser-powered and much-touted ChemCam.

The images above and below were acquired by ChemCam’s Remote Micro-Imager on August 21, the 15th “Sol” of the mission. A full-sized image accessed from the public MSL mission site, it’s been brightened quite a bit to show the details of the target rocks.

Mounted to Curiosity’s “head”, just above its Mastcam camera “eyes”, ChemCam combines a powerful laser with a telescope and spectrometer that can analyze the light emitted by zapped materials, thereby determining with unprecedented precision what Mars’ rocks are really made of.

So even though the rover hasn’t actually roved anywhere yet, it’s still performing valuable scientific investigations of Mars — without moving a single wheel. (UPDATE: actually, Curiosity has begun to do some roving — here are some images of its first wheel tracks!)

Read: Curiosity Blasts First Mars Rock with Powerful Laser Zapper

Because ChemCam uses a laser, Curiosity can examine many targets — up to a dozen — within a small time period without having to drive right up to them. Even the dustiest rocks won’t pose a problem for ChemCam – one or two zaps with its laser will be enough to vaporize any loose surface material.

In addition to searching for the building blocks of life hidden inside rocks, ChemCam will also serve a precautionary role for future explorers by helping identify the potential toxicity of Mars’ soil and dust. When astronauts one day land on Mars, they are going to get dusty. It’s important to know if Mars’ dust contains anything dangerous like lead, arsenic (and who knows what else!)

Curiosity’s Sundial Carries a Message of Hope

Image from Curiosity's Mastcam shows the rover's MarsDial (NASA/JPL-Caltech)

 A recent high-definition image from Curiosity’s Mastcam shows the rover’s sundial (NASA/JPL-Caltech)

While Curiosity is definitely loaded up with some of the most high-tech instruments ever made to investigate the surface of Mars, it also carries a very low-tech instrument: a sundial (aka the “MarsDial”) which can be used to determine the position of the Sun in the sky and the season on Mars just like they do here on Earth. Curiosity’s sundial also has additional color calibration tools for the rover’s Mastcam, which captured the image above on August 19 — the 13th “Sol” of the mission.

The connection between a device invented by people thousands of years ago being in use today on a robotic explorer on another planet didn’t go unnoticed by the Mars Exploration Rover team either; in addition to the words “Mars 2012” and “To Mars, To Explore” around its top bezel, Curiosity’s sundial also carries a message of history, hope and inspiration printed along its edges…

Along with line drawings and the word for “Mars” in sixteen languages, Curiosity’s sundial bears the following inscription:

“For millennia, Mars has stimulated our imaginations. First, we saw Mars as a wandering star, a bringer of war from the abode of the gods. In recent centuries, the planet’s changing appearance in telescopes caused us to think that Mars had a climate like the Earth’s. Our first space age views revealed only a cratered, Moon-like world, but later missions showed that Mars once had abundant liquid water. Through it all, we have wondered: Has there been life on Mars? To those taking the next steps to find out, we wish a safe journey and the joy of discovery.”

Curiosity’s successful landing on Mars at 10:31 p.m. on August 5, 2012 (PDT) was only the first (although very exciting!) step of its mission, and the first of hopefully many next steps to explore our neighboring world. Perhaps one day this message will be revisited by human explorers on Mars who may then reflect back on how it all began, and all of the innovations, hope and — well, curiosity — that made each of their rust-dusted steps possible.

Follow the sun, Curiosity!
