CAPE CANAVERAL, FL – NASA’s car sized Curiosity Mars rover has resumed full science operations and driving following a six day long halt to research activities due to concerns about an electrical power system glitch, which have now been resolved.

On Nov. 17, engineers noticed a fluctuation in voltage on Curiosity that caused the robots handlers to stop science activities and driving towards mysterious Mount Sharp while they searched for the root cause of the electrical issue.

NASA says that the voltage change did not impact the rovers safety or health and the team was acting out of an abundance of caution while investigating the situation from millions of miles away back on Earth.

“The vehicle’s electrical system has a “floating bus” design feature to tolerate a range of voltage differences between the vehicle’s chassis — its mechanical frame — and the 32-volt power lines that deliver electricity throughout the rover. This protects the rover from electrical shorts,” NASA said in a statement.

Curiosity’s voltage level had been about 11 volts since landing day and had declined to about 4 volts on Nov. 17. The electrical issue did not trigger the rover to enter a safe-mode status.

Engineers amassed a list of possible causes for the voltage change while suspending science operations and roving across the Martian crater floor where Curiosity landed nearly a year and a half ago in August 2012.

“We made a list of potential causes, and then determined which we could cross off the list, one by one,” said rover electrical engineer Rob Zimmerman of NASA’s Jet Propulsion Laboratory, Pasadena, Calif.

NASA says that the likely cause is an internal short stemming from the Radioisotope Thermoelectric Generator (RTG) – the rovers nuclear power source.

RTG’s have been commonly used on many NASA missions that also experienced occasional shorts and that had no long term impact or loss of capability on their flights.

“This type of intermittent short has been seen in similar RTGs, including the one on the Cassini spacecraft, which has been orbiting Saturn for years. The rover electronics are designed to operate at variable power supply voltages, so this is not a major problem,” says Curiosity team member Ken Herkenhoff of the USGS in a mission update.

The voltage level had returned its normal level of 11 volts on its own by Nov. 23, when the team had decided to resume science operations.

So it is possible that the same type of intermittent voltage change could recur in the future.

Meanwhile the rover has resumed her epic trek to Mount Sharp and is expected to arrive at the base of the mountain sometime in mid-2014.

This past weekend, the robot delivered additional portions of powdered rock to the CheMin and SAM labs inside the rover. The sample was collected 6 months ago after drilling into a rock nicknamed “Cumberland” and will supplement prior measurements.

Curiosity has already accomplished her primary science goal of discovering a habitable zone at her landing site.

Scientists expect to broaden the region of Martian habitability once the 1 ton robot begins the ascent of Mount Sharp to investigate the sedimentary layers in the lower reaches of the towering 3 mile (5 km) high mountain, that record Mars geologic and climatic history over a time span of billions of years.

And as both of NASA’s rovers Curiosity and Opportunity ascend Martian mountains, they’ll be joined next September 2014 by a pair of new Martian orbiters from the US and India – MAVEN and MOM – that will significantly expand Earth’s invasion force at the Red Planet.

India’s MOM Mars Probe Images Earth’s Children Prior to Nail Biting Red Planet Insertion

CAPE CANAVERAL, FL – MOM is looking at you, kid!

And if the spectacular new image of billions of Earth’s children captured by India’s Mars Orbiter Mission (MOM) is any indication (see above), then we can expect absolutely gorgeous scenes of the Red Planet once the groundbreaking probe arrives there in September 2014.

But despite all that’s been accomplished so far, the space drama is still in its infant stages – because MOM still needs to ignite her thrusters this weekend in order to achieve escape velocity, wave good bye to Earth forever and eventually say hello to Mars!

The picture – snapped from Earth orbit – is focused on the Indian subcontinent, the probes origin.

MOM has captured the imagination of space enthusiasts worldwide.

And she’s the pride of all India – as the country’s first ever interplanetary space mission.

During testing of the MOM probes payloads – while it’s still flying in a highly elliptical orbit around our Home Planet – engineers from India’s space agency turned the crafts camera homewards to capture the “First ever image of Earth Taken by Mars Color Camera,” according to the Indian Space Research Organization (ISRO).

The beautiful image was taken on Nov. 20 at around 1350 hrs (IST) from a height of almost 70,000 km above earth and has a spatial resolution of 3.5 km, said ISRO.

The image also gives a rather good approximation of what MOM’s color camera will actually see from apoapsis after reaching the Red Planet since the probe will enter a similarly highly elliptical orbit around Mars – ranging in altitude from 366 kilometers (km) x 80,000 kilometers (km).

Following a 10 month interplanetary cruise, MOM is due to arrive in the vicinity of Mars on September 24, 2014 to study the Red Planets’ atmosphere.

At that time, the 440 Newton liquid fueled main engine must fire precisely as planned during the absolutely essential Mars orbital insertion burn to place the probe into orbit about Mars.

But before MOM can accomplish anything at Mars, she must first successfully fire her main engine – to complete the crucial departure from Earth and Trans Mars Insertion (TMI) scheduled for this Saturday!

MOM’s picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from the ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, precisely injected the spacecraft into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.

Since then the engine has fired 6 times to gradually raise the spacecrafts apogee.

The most recent orbit raising maneuver occurred at 01:27 hrs (IST) on Nov 16, 2013 with a burn time of 243.5 seconds increased the apogee from 118,642 km to 192,874 km.

The nail-biting final main engine burn of 1351 seconds is set for this weekend on Dec. 1. It will place MOM on a precise interplanetary trajectory to the Red Planet.

If all continues to goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).

The low cost $69 Million MOM mission is the first of two new Mars orbiter science probes from Earth that flawlessly blasted off for the Red Planet this November.

Half a world away, NASA’s $671 Million MAVEN orbiter launched as scheduled on Nov. 18 – from Cape Canaveral, Florida.

Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.

The MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist Prof. Bruce Jakosky told Universe Today.

Astronauts To Chase Down Turkey Meal For Thanksgiving

Judging from the way those food packets are floating around, looks like the folks on the International Space Station will have to catch their turkey! NASA astronauts Rick Mastracchio and Mike Hopkins, two of the six people working on Expedition 38, recently shared their plans for U.S. Thanksgiving on Thursday.

“Though we miss our families, it’s great to be in space. As astronauts, this is what we train for and this is where we want to be. Opportunities to fly in space are rare, so we have to take advantage of them whenever they occur,” Hopkins said in the message.

The best part of this missive? Watching the astronauts casually toss the microphone back and forth in between their statements. That’s the fun of recording in microgravity.

Thanksgiving will be a full workday on station as the astronauts continue to work on their experiments. A recent status report indicated that Mastracchio (the crew medical officer) was examining Hopkins’ eyes as part of ongoing work looking at how microgravity affects ocular health. Flight controllers also moved one of the solar arrays for Mastracchio to take pictures and monitor how the mast is doing “for future inspections”, NASA stated.

How Could We Recycle Satellites For Newer Missions?

Space junk is an ongoing concern for NASA, the European Space Agency and many others. After satellites live out their useful lives in orbit, more and more the agencies are trying to either move them far away from Earth, or to have the satellites burn up in the atmosphere. That’s basically to preserve orbital slots around the planet for others, and to reduce the risk of collisions.

But here’s an alternate approach — why not leave a few satellites handy for other missions to pick up? ESA recently opened a tender exploring this idea, and put a few thoughts out in a press release. Maybe leftover solid rocket fuel could be re-used. Metal alloys could be ground down for potential 3-D printing materials. Life support systems could use biodegradable materials. Since it costs so much to haul stuff into orbit, maybe it might be worthwhile to leave some available for future missions, ESA reasons.

“ESA’s new invitation for ‘Sustainable Materials Concepts’ is seeking companies to study various concepts of this approach, including considering the kinds of materials that could be reused as biological or technical nutrients – serving as resources for new other processes,” ESA stated.

“Also under consideration: what sustainable materials might replace current space-grade materials such as titanium and aluminium alloys or carbon-fibre epoxy resins? And how might the use of materials as biological or technical nutrients work in practice?”

What do you think satellites could be used for? Leave your thoughts in the comments.

NASA’s LADEE Probe Starts Science Study of Thin Lunar Atmosphere and Dusty Mystery

KENNEDY SPACE CENTER, FL – NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) has descended to its planned low altitude orbit and begun capturing science data on its ground breaking mission to study the Moon’s ultra tenuous atmosphere and dust using a spacecraft based on a revolutionary new design aimed at speeding development and cutting costs.

LADEE set sail for Earth’s nearest neighbor during a spectacular night time launch atop the maiden flight of an Air Force Minotaur V rocket on Sept. 6 from NASA’s Wallops Island launch facility on Virginia’s Eastern shore.

The flawless launch thrilled spectators up and down virtually the entire US East coast region and yielded many memorable snapshots.

Following a month long voyage and three and a half long looping orbits of the Earth, LADEE successfully fired its main engine for 4 minutes and 12 seconds on Oct. 6 and successfully entered lunar orbit, Dawn McIntosh, LADEE deputy project manager at NASA Ames Research Center, told Universe Today in an exclusive interview.

A series of engine firings over the past month gradually circularized and lowered LADEE into its final science orbit around our Moon while engineers checked out the spacecraft during the commissioning phase of the mission.

The do or die initial Lunar Orbit Insertion burn (LOI-1) allowed LADEE to be captured into a highly elliptical, equatorial lunar orbit, said McIntosh.

“Two additional LOI burns on Oct. 6 and Oct 9 lowered LADEE to an approximately 4 hour orbit with a periapsis altitude of 234 Kilometers (km) and apoapsis altitude of 250 km” McIntosh told me.

The trio of LOI main engine firings used up most of LADEE’s precious on board fuel.

“LADEE launched with 134.5 kilograms (kg) of fuel. Post LOI-3, 80% of our fuel has been consumed,” said McIntosh.

“Additional orbit-lowering maneuvers with the orbital control system (OCS) and reaction control system (RCS) of approximately 40 seconds were used to get LADEE into the science orbit.

The spacecraft finally entered its planned two hour science orbit around the moon’s equator on Nov. 20.

Its flying at an extremely low altitude ranging from merely eight to 37 miles (12-60 kilometers) above the moon’s surface.

By circling in this very low altitude equatorial orbit, the washing machine sized probe will make frequent passes crossing from lunar day to lunar night enabling it to precisely measure changes and processes occurring within the moon’s tenuous atmosphere while simultaneously sniffing for uplifted lunar dust in the lunar sky.

The remaining fuel will be used to maintain LADEE’s orbit during the approximately 100 day long science mission. The mission length is dictated by the residual fuel available for thruster firings.

The purpose of LADEE is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface. In turn this will lead to a better understanding of other planetary bodies in our solar system and beyond.

“A thorough understanding of the characteristics of our lunar neighbor will help researchers understand other small bodies in the solar system, such as asteroids, Mercury, and the moons of outer planets,” said Sarah Noble, LADEE program scientist at NASA Headquarters in Washington.

By studying the raised dust, scientists also hope to solve a 40 year old mystery – Why did the Apollo astronauts and early unmanned landers see a glow of rays and streamers at the moon’s horizon stretching high into the lunar sky.

The $280 million probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.

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

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

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

LADEE arrived at the Moon last month in the midst of the US government shutdown – which negatively impacted a host of other NASA missions. Only a ‘skeleton crew’ was available.

“All burns went super well,” Worden told me. And he is extremely proud of the entire team of “dedicated” professional men and women who made it possible during the shutdown.

“It says a lot about our people’s dedication and capability when a skeleton crew’ can get a new spacecraft into lunar orbit and fully commissioned in the face of a shutdown!” Worden said to Universe Today.

Now the real science begins for LADEE and the team.

Stay tuned here for continuing LADEE news

Inspiration Mars Wants To Work With NASA To Get To The Red Planet

CORRECTION: This article has been updated after more information was received from Inspiration Mars. Tito was highlighting other countries’ interest in the Red Planet in his testimony and has no plans at this time to work with anyone but NASA.

Remember that proposal to send a couple in the direction of the Red Planet, loop around it and then come back to Earth? The founder of the Inspiration Mars project, Dennis Tito, outlined more details of his proposal before the House Science Subcommittee on Space yesterday (Nov. 20).

Inspiration Mars has released an Architecture Study Report that is the fruits of a 90-day study done not only by the foundation itself, but also working with “NASA centers and industry partners” to figure out the best way to launch humans there in late 2017 or 2018. ~~But if it’s delayed, Tito is prepared to go to Russia or China instead, he warns.~~

Here’s the high-level summary:

Two launches using NASA’s forthcoming Space Launch System, one for cargo and one for crew;
The crew module would be from the crew transportation vehicle that NASA selected under its commercial crew program (see this Universe Today story yesterday for an update on funding concerns on that program);
The cargo and crew vehicles would dock in space and then head out to Mars.

If the NASA proposal doesn’t work out, Tito warned Russia may be interested as well. ~~said he’s quite prepared to bring his idea to another country, Russia~~. (Recall that Tito flew into space in 2001 on a Russian Soyuz spacecraft as a private citizen, so he does have connections over there.)

“Given Russia’s clear recognition of the value and prestige of accomplishments in human space exploration, and their long-time interest in exploring Mars, my personal belief is that in all likelihood the Energia super-heavy rocket revival announcement signals Russian intent to fly this mission in 2021,” Tito stated.

“Their heavy lift rocket, along with their other designs for modules and the Soyuz, can fly this mission with modest upgrades to their systems.”

~~A third option would be using Chinese capabilities, he added,~~ The Chinese may also be interested, he said, because the country — reportedly developing a large space station of its own — is likely “contemplating this opportunity to be the first on Mars.” Tito said he is informing Congress of his plans to go elsewhere as a “civic duty”, and that he wants to give NASA the first shot.

More food for thought as Congress mulls how much money to allocate to NASA in fiscal 2014. And Tito had strong words about his feelings on the funding: “If I may offer a frank word of caution to this subcommittee: The United States will carry out a Mars flyby mission, or we will watch as others do it – leaving us to applaud their skill and their daring.”

Human Spaceflight, Planetary Missions Face Potential Cuts in Latest NASA Budget Negotiations

While 2014 budget negotiations are not finalized yet, there’s already some noise of concern in different space communities that depend on NASA. Here’s a brief roundup of some of the news lately:

Could the Cassini Saturn mission get the axe? Wired’s Adam Mann warns that NASA may not be able to fund all of its planetary science missions in the coming year. Based on a statement that Jim Green, NASA’s planetary science director, made to an agency advisory council earlier this month, Mann narrows in on the Curiosity and Cassini missions as the big flagship missions that are requiring the most in terms of resources. Cassini is functioning perfectly and providing reams of data from Saturn and its moons, causing concern from planetary scientists about losing it early.

Only one commercial crew partner? NASA issued a cautious news release this week saying it is prepared to launch Americans from their own soil in 2017, “subject to the availability of adequate funding.” The agency is now moving into a new phase of its commercial crew program called Commercial Crew Transportation Capability (CCtCap), saying it is prepared to “award one or more CCtCap contracts no later than September 2014.” That means that the three companies currently funded — Boeing Co., Sierra Nevada Corp. and SpaceX — may face stiff competition for more money.

New report suggesting stopping NASA’s human spaceflight program: Before reading any further, do not jump to conclusions — making recommendations like this is a common practice by the Congressional Budget Office, which looks at all possibilities as it presents options for spending. Still, Space Politics’ Jeff Foust presents the report and generates some interesting comments after his story about the value of human spaceflight. For context, NASA and its international agency partners will need to make a decision fairly soon about continuing space station operations past 2020, so it’s possible the human spaceflight program could change.

What do you think of these proposals? Let us know in the comments.

What Day 1 On The International Space Station Was Like For The Astronauts

There wasn’t a lot of elbow room when six people from the Endeavour shuttle floated into the baby International Space Station on Dec. 10, 1998, but the cramped quarters resonated with possibility in STS-88 commander Bob Cabana’s mind.

“It’s hard to believe 15 years ago we put those first modules together, and we have this facility today that’s the size of a football field,” said Cabana in an interview today (Nov. 20) with Universe Today.

Cabana, who is now the director of the Kennedy Space Center, oversaw a complex mission that included joining the Russian Zarya and U.S. Unity modules, three spacewalks to get the modules powered and ready for humans to enter, and the pressure of public relations activities surrounding the opening of the station itself.

“That was a very special day, when we went into Unity and Zarya for the first time. There was a lot of excitement and anticipation,” Cabana said. He and Russian Sergei Krikalev — who would go on to become the person who spent the most time in space, at 803 days — entered the tiny hatches side by side to emphasize the international participation.

As is typical of spaceflight, the astronauts spent most of their day at work, busily waking up the station and testing its systems. NASA astronauts Jerry Ross and James Newman put together a communications system. Other crew members tested the videoconference equipment — important for press conferences as well as talking to scientists on the ground. Equipment and supplies in Zarya had to be unstowed and organized.

There also was the first repair on station, when Krikalev and NASA astronaut Nancy Currie replaced a faulty unit in Zarya “which controlled the discharging of stored energy from one of the module’s six batteries,” NASA wrote in an update at the time.

Cabana wanted his crew to get eight hours of sleep, but the excitement of that first day kept everybody up until 2:30 in the morning despite the wakeup call coming at 7 a.m.

“We were talking about what the ISS means, what will be accomplished with this cornerstone,” Cabana recalled, and said he is pleased with what has come to pass in the next 15 years. “It had come true. Everything we thought that could be has come together. That was a very special night, thinking about the future and how important the International Space Station was.”

The heaviest construction finished in 2011, and larger crews of six were allowed on board rather than the beginning crews of just three. NASA is now trying to position the station as a venue for microgravity science to justify the expense of running it. The astronauts, however, must balance their time doing science with the normal chores and maintenance the station requires. (The recent Expedition 35/36 missions were extremely productive in terms of science return, NASA astronaut Chris Cassidy told Universe Today in a past interview.)

All buildings on Earth require upgrades from time to time to stay safe and up to date, and the ISS is no different. Cabana said analysis will be done to “extend the life on some of the modules, but we don’t see that as a large issue.” The reason? The crews do “an outstanding job” keeping the station humming along with routine maintenance, he said.

Today (Nov. 20) marks the 15th anniversary of Zarya’s launch into orbit. The station partners are currently committed until 2020, meaning negotiations are forthcoming to see what to do with the station in the years afterwards. It’s unclear what will happen next — the recession is still reverberating in the United States and overseas — but today, the agencies focused on the successes.

Each partner agency tweeted facts and science concerning the ISS under the hashtag #ISS15, and invited people using all forms of social media to share their thoughts on the station. What are some notable things about the station, and what is a good use of it in the future, in your opinion? Let us know in the comments.
