A new time-lapse photomosaic shows China’s Yutu rover dramatically trundling across the Moon’s stark gray terrain in the first week after she rolled all six wheels onto the desolate lunar plains.

Our complete time-lapse mosaic (see below) shows Yutu at three different positions trekking around the landing site, and gives a real sense of how it is maneuvering around – on the 1st Lunar Day.

The 360-degree panoramic mosaic was created from images captured by the color camera aboard China’s Chang’e-3 lander, the country’s first spacecraft to successfully soft land on the Moon.

The time-lapse mosaic was stitched together by the imaging team of scientists Ken Kremer and Marco Di Lorenzo using images just released on a Chinese language website.

We integrated the wide screen panorama with additional images of Yutu taken by the lander as she roved around the right side of the mothership during her 1st Lunar Day – to create the new time-lapse panorama.

To me the moonscape is rather reminiscent of the scenery from NASA’s manned Apollo lunar landing missions which took place over 4 decades ago – from 1969 to 1972.

The first portrait of Yutu was taken shortly after it first drove off the 1200 kg Chang’e-3 lander on Dec. 15. The last Yutu position shows her heading off to the south and departing the landing site forever.

She’s not ever coming back to see the stationary lander again, according to China’s Chang’e-3 mission team.

Yutu, which translates as ‘Jade Rabbit’, is on her own from now on.

Chang’e-3 safely touched down on the Moon at Mare Imbrium near the Bay of Rainbows on Dec. 14, 2013.

Seven hours later, the piggybacked 140 kg Yutu robot drove off a pair of ramps, onto the Moon and into the history books.

Here is the initial black and white panoramic version from the Chang’e-3 navigation camera – which we assembled from screenshots taken as it was twirling about in a CCTV news video report.

The Chang’e-3 mothership and Yutu rover are now working during their 2nd Lunar Day, having survived the harsh extremes of their 1st Lunar Night when temperatures plummeted to below minus 180 degrees Celsius, or minus 292 degrees Fahrenheit.

They have resumed full operation and are conducting research investigations. Each is equipped with four science instruments.

All the equipment is functioning well except alas for the color camera used to snap the images for the photomosaics herein.

China’s official Xinhua new agency reports that the instruments aboard the lander and rover have each collected a large amount of data about the Moon, Earth and celestial objects.

Scientists have created a star atlas around the constellation Draco and used the ground penetrating radar to survey the moon’s subsurface and soil structure to depths of 10 to 140 meters.

Meanwhile as China’s Yutu rover trundles across pitted moonscapes, NASA’s Opportunity rover is in the midst of Martian mountaineering at the start of Decade 2 on the Red Planet and younger sister Curiosity is speeding towards the sedimentary layers of Mount Sharp.

Stay tuned here for Ken’s continuing Chang’e-3, Orbital Sciences, SpaceX, commercial space, LADEE, Mars and more news.

The Moon Occults Saturn in the Dawn this Weekend

 Mark your calendars: the first in a series of interesting occultations of Saturn by the Moon for 2014 starts this weekend.

The year 2014 features 11 occultations of the planet Saturn by the Moon, and there are 23 total for 2014 of every planet except Neptune and Jupiter.

An occultation occurs when one foreground celestial object completely obscures another. Technically, a total solar eclipse is an occultation of the Sun by the Moon, although it’s never referred to as such. The term finds modern usage mainly for the blocking of stars and planets by the Moon. Very occasionally, an asteroid or planet can occult a distant star as well.

And yes, the modern astronomical term “occultation” traces its hoary roots back to the days when astronomy was intertwined with the pseudoscience of astrology.  To this day, the term still makes some folks wonder if astronomers are secretly casting horoscopes. Trust us, you’re still on a solid astronomical footing to use the term “occultation.”

Unfortunately, the January 25th occultation of Saturn by the Moon will only grace part of Antarctica, southern Argentina and Chile, and the Falkland Islands post-sunrise. The rest of us still will see a very photogenic pass of Saturn near the waning crescent Moon on the morning of Saturday, January 25th. The Moon will pass just about a degree — two times its apparent width — south of Saturn for northern hemisphere observers.

Both the Moon and Saturn will reside in the astronomical constellation of Libra this weekend during closest passage. The pair will rise around 2 AM local. After their brief tryst, the Moon will head towards New on January 30th while Saturn will continue to rise successively earlier as its heads towards opposition and the start of evening Saturn observing season on May 10th, 2014.

January 2014 is also notable for having two New Moons, an occurrence informally known as a Black Moon. This occurs again this year in March, and February 2014 is devoid of a New Moon. February is the only month that can be “missing a Moon phase” as it’s the only one shorter the synodic period of 29.5 days, in which the Moon returns to like phase.

In the telescope, Saturn will present a +0.8 magnitude disk 16” across (38” with rings from tip-to-tip). Saturn’s rings are tipped open to our line of sight by about 22 degrees in 2014, and are widening towards a maximum of 27 degrees in 2016 through 2017. If you have an equatorial telescope with tracking capability, it may be possible this weekend to follow Saturn up into the daytime sky. Though Saturn isn’t quite bright enough to see in the daytime unaided, it might just be possible to spy using binoculars on the 25th using the nearby crescent Moon as a guide.  Saturn is a tough daytime target to be sure, but it’s not impossible to acquire with a little skill and patience.

The current cycle of occultations of Saturn began on December 1st, 2013 and ends on November 22nd, 2014. The cycle will move progressively northward through the year.

The Moon and Saturn put on a repeat performance over almost the same exact location (this time in darkness) on April 17th, 2014, and the best event in the cycle for North America will be the August 31st daytime occultation of Saturn by the waxing crescent Moon.

Now for the wow factor of what you’re seeing. On Saturday morning, the Moon is just over 371,000 kilometres distant, or a little over a light second away. Saturn is over four thousand times more remote at just over 10.1 astronomical units (AUs) distant, which works out to 1.5 billion kilometres, or over 83 light minutes away.  And although the Moon is over a 112 times larger in apparent diameter than Saturn as seen from the Earth, the globe of Saturn is actually over 34 times bigger.

And though we’ve been to the Moon lots since the dawn of the Space Age, only two spacecraft (Voyagers 1 and 2) have made brief flybys of the ringed world, and only one – Cassini – has orbited it. Note that China’s Chang’e-3 lander and rover are about to experience their second sunset this weekend as well from the lunar surface since landing on the Moon last month.

And although lots of planets get occulted by the Moon in 2014, no stars brighter than +1st magnitude lie in its path. In fact, the next cycle of bright star occultations by the Moon doesn’t resume until the Moon meets Aldebaran in January 29th, 2015.

There are, however, over a 100 lesser events involving the Moon occulting naked eye stars worldwide in 2014. Two such events occur this week as well, when the 48% illuminated Moon occults the +4.5th magnitude star Lambda Virginis for west-central South America on the morning of January 24th, and the occultation of the +2.8th magnitude star Alpha Librae  (Zubenelgenubi) for central Asia on January 25th.

Don’t miss these celestial events, and be sure to send those pics in to Universe Today… there’s something for everyone happening in the sky this week worldwide!

Chinese space officials have at last released much higher quality versions of the 1st color imagery captured by China’s first spacecraft to soft land on the surface of the Earth’s Moon; Chang’e-3.

For the enjoyment of space enthusiasts worldwide, we have assembled the newly released imagery to create the ‘1st 360 Degree Color Panorama from China’s Chang’e-3 Lunar Lander.’ See above and below two versions in full resolution, as well as an interactive version – showing the fabulous view on the 1st Lunar Day.

The moonscape panorama shows the magnificent desolation of the pockmarked gray lunar plains at the mission’s touchdown site at Mare Imbrium. It is starkly reminiscent of NASA’s manned Apollo lunar landing missions which took place over 4 decades ago – from 1969 to 1972.

And this spectacular view may well be a harbinger of what’s coming next – as China’s leaders consider a manned lunar landing perhaps a decade hence, details here.

See above a cropped portion – focusing on the piggybacked ‘Yutu’ lunar rover and the impressive tracks it left behind after it initially rolled all six wheels onto the surface; and which cut several centimeters deep into the loose lunar regolith on Dec. 15, 2013.

The beautiful imagery snapped by China’s history making Chang’e-3 lunar lander on 17 and 18 December 2013 – during its 1st Lunar day – was released in six separate pieces on the Chinese language version of the Chinanews website, over the weekend.

See below the compete version of the 360 degree panorama stitched together by the imaging team of scientists Ken Kremer and Marco Di Lorenzo.

We have also enhanced the imagery to improve contrast, lighting and uniformity to visibly reveal further details.

For comparison, below is the initial black and white panoramic version seen by the landers navigation camera – which we assembled from screenshots taken as it was twirling about in a CCTV news video report.

Alas, one bit of sad news is that it appears the 1200 kg lander’s color camera apparently did not survive the 1st frigid night since it reportedly wasn’t protected by a heater.

For a collection of new and higher quality Chang’e-3 mission photos – including the 1st portraits of the Earth taken from the Moon’s surface in some 40 years – please check my recent article; here.

Check this link – to view a 360 degree interactive version of the first Chang’e-3 color panorama – created by space enthusiast Andrew Bodrov. He has added in a separate image of the Earth snapped by the lander.

China’s action to release higher quality imagery is long overdue and something I have urged the Chinese government to do on several occasions here so that everyone can marvel at the magnitude of China’s momentous space feat.

We applaud the China National Space Administration (CNSA) for this new release and hope they will publish the higher resolution digital versions of all the imagery taken by the Chang’e-3 mothership and the Yutu rover and place everything onto a dedicated mission website – just as NASA does.

Here’s the pair of polar views of the 360 degree lunar landing site panoramas (released last week) – taken by each spacecraft and showing portraits of each other.

China’s history making moon robots – the Chang’e-3 lander and Yutu rover – are now working during their 2nd Lunar Day. They have resumed full operation – marking a major milestone in the new mission.

It’s remarkable to consider that although they were just awoken last weekend on Jan. 11 and Jan. 12 from the forced slumber of survival during their long frigid 1st lunar night, they are now already half way through Lunar Day 2 – since each day and night period on the Moon lasts two weeks.

China is only the 3rd country in the world to successfully soft land a spacecraft on Earth’s nearest neighbor after the United States and the Soviet Union.

Meanwhile as China’s Yutu rover trundles across pitted moonscapes, NASA’s Opportunity rover is in the midst of Martian mountaineering at the start of Decade 2 on the Red Planet and younger sister Curiosity is speeding towards the sedimentary layers of Mount Sharp.

Chang’e 3 Lander Beams Back New Lunar Panorama Photos

AfricaCredit: Chinanews.com

Little by little we’re getting sharper, clearer pictures from the Chinese Chang’e 3 moon mission. Yesterday the lander beamed back a series of new photos taken with its panoramic camera. Stitched together, they give us a more detailed and colorful look of the rover’s surroundings in northern Mare Imbrium. I’ve ordered the images starting with a nice crisp view of the Yutu rover; from there we turn by degree to the right across the five frames. The final mosaic unfortunately doesn’t have the resolution yet of the other images. Perhaps one will be published soon.

One thing that stands out to my eye when looking at the photos is the brown color of the lunar surface soil or regolith. Color images of the moon’s surface by the Apollo astronauts along with  their verbal descriptions indicate a uniform gray color punctuated in rare spots by patches of more colorful soils.

The famous orange soil scooped up by Apollo 17 astronaut Eugene Cernan comes to mind. Because Apollo visited six different moonscapes – all essentially gray – it makes me wonder if the color balance in the Chinese images might be off. Or did Chang’e 3 just happen to land on browner soils?

Extend ISS to 2050 as Stepping Stone to Future Deep Space Voyages – Orbital VP/Astronaut tells Universe Today

Story updated[/caption]

WALLOPS ISLAND, VA – Just days ago, the Obama Administration approved NASA’s request to extend the lifetime of the International Space Station (ISS) to at least 2024. Ultimately this will serve as a stepping stone to exciting deep space voyages in future decades.

“I think this is a tremendous announcement for us here in the space station world,” said Bill Gerstenmaier, associate administrator for NASA’s Human Exploration and Operations Mission Directorate, at a press briefing on Jan. 8.

But there’s really “no reason to stop it there”, said Frank Culbertson, VP at Orbital Sciences and former NASA astronaut and shuttle commander, to Universe Today when I asked him for his response to NASA’s station extension announcement.

“It’s fantastic!” Culbertson told me, shortly after we witnessed the picture perfect blastoff of Orbital’s Antares/Cygnus rocket on Jan. 9 from NASA’s Wallops launch facility in Virginia, bound for the ISS.

“In my opinion, if it were up to me, we would fly it [the station] to 2050!” Culbertson added with a smile. “Of course, Congress would have to agree to that.”

Gerstenmaier emphasized that the extension will allow both the research and business communities to plan for the longer term and future utilization, be innovative and realize a much greater return on their investments in scientific research and capital outlays.

“The station is really our stepping stone,” Robert Lightfoot, NASA Associate Administrator, told me at Wallops following Antares launch.

The Alpha Magnetic Spectrometer (AMS) – which is searching for elusive dark matter – was one of the key science experiments that Gerstenmaier cited as benefitting greatly from the ISS extension to 2024. The AMS is the largest research instrument on the ISS.

The extension will enable NASA, the academic community and commercial industry to plan much farther in the future and consider ideas not even possible if the station was de-orbited in 2020 according to the existing timetable.

Both the Antares rocket and Cygnus cargo freighter are private space vehicles developed and built by Orbital Sciences with seed money from NASA in a public-private partnership to keep the station stocked with essential supplies and research experiments and to foster commercial spaceflight.

So I asked Culbertson and Lightfoot to elaborate on the benefits of the ISS extension to NASA, scientific researchers and commercial company’s like Orbital Sciences.

“First I think it’s fantastic that the Administration has committed to extending the station, said Culbertson. “They have to work with the ISS partners and there is a lot to be done yet. It’s a move in the right direction.”

“There is really no reason to stop operations on the space station until it is completely no longer usable. And I think it will be usable for a very long time because it is very built and very well maintained.”

“If it were up to me, we would fly it to 2050!”

“NASA and the engineers understand the station very well. I think they are operating it superbly.”

“The best thing about the station is it’s now a research center. And it is really starting to ramp up. It’s not there yet. But it is now finished [the assembly] as a station and a laboratory.”

“The research capability is just starting to move in the right direction.”

The Cygnus Orbital 1 cargo vehicle launched on Jan. 9 was loaded with approximately 2,780 pounds/1,261 kilograms of cargo for the ISS crew for NASA including vital science experiments, computer supplies, spacewalk tools, food, water, clothing and experimental hardware.

The research investigations alone accounted for over 1/3 of the total cargo mass. It included a batch of 23 student designed experiments representing over 8700 students sponsored by the National Center for Earth and Space Science Education (NCESSE).

“So extending it [ISS] gives not only commercial companies but also researchers the idea that ‘Yes I can do long term research on the station because it will be there for another 10 years. And I can get some significant data.”

“I think that’s really important for them [the researchers] to understand, that it will be backed for that long time and that they won’t be cut off short in the middle of preparing an experiment or flying it.”

“So I think that first of all it demonstrates the commitment of the government to continue with NASA. But also it presents a number of opportunities for a number of people.”

What does the ISS extension mean for Orbital?

The purpose for NASA and Orbital Sciences in building Antares and Cygnus was to restore America’s ability to launch cargo to the ISS – following the shutdown of NASA’s space shuttles – by using commercial companies and their business know how to thereby significantly reduce the cost of launching cargo to low Earth orbit.

“As far as what it [the ISS extension] means for Orbital and other commercial companies – Yes, it does allow us to plan long term for what we might be able to do in providing a service for NASA in the future,” Culbertson replied.

“It also gives us the chance to be innovative and maybe invest in some improvements in how we can do this [cargo service] – to make it more cost effective, more efficient, turnaround time quicker, go more often, go a lot more often!”

“So it allows us the chance to think long term and make sure we can get a return on our investment.”

What does the ISS extension mean for NASA?

“The station is really our stepping stone,” Robert Lightfoot, NASA Associate Administrator, told Universe Today. “If you use that analogy of stepping stones and the next stone. We need to use this stone to know what the next stone looks like. So we can get ready. Whether that’s research or whether that things about the human body. You don’t want to jump off that platform before you are ready.”

“We are learning every day how to live and operate in space. Fortunately on the ISS we are close to home. So if something comes up we can get [the astronauts] home.”

The ISS extension is also the pathway to future exciting journey’s beyond Earth and into deep space, Culbertson and Lightfoot told Universe Today.

“It actually also presents a business opportunity that can be expanded not just to the station but to other uses in spaceflight, such as exploration to Asteroids, Mars and wherever we are going,” said Culbertson.

And we hope it will extend to other civilian uses in space also. Maybe other stations in space will follow this one and we’ll be able to participate in that.”

Lightfoot described the benefits for astronaut crews.

“The further out we go, the more we need to know about how to operate in space, what kind of protection we need, what kind of research we need for the astronauts,” said Lightfoot.

“Orbital is putting systems up there that allow us to test more and more. Get more time. Because when we get further away, we can’t get home as quick. So those are the kinds of things we can do.

“So with this extension I can make those investments as an Agency. And not just us, but also our academic research partners, our industry partners, and the launch market too is part of this.”

He emphasized the benefits for students, like those who flew experiments on Cygnus, and how that would inspire the next generation of explorers!

“You saw the excitement we had today with the students at the viewing area. For example with those little cubesats, 4 inches by 4 inches, that they worked on, and got launched today!”

“That’s pretty cool! And that’s exactly what we need to be doing!

“So eventually they can take our jobs. And as long as they know that station will be there for awhile, the extension gives them the chance to get the training and learning and do the research we need to take people further out in space.”

“The station is the stepping stone.”

“And it really is important to have this station extension,” Lightfoot explained to me.

The Jan. 9 launch of the Orbital-1 mission is the first of eight operational Antares/Cygnus flights to the space station scheduled through 2016 by Orbital Sciences under its $1.9 Billion Commercial Resupply Services (CRS) contract with NASA to deliver 20,000 kg of cargo to orbit.

Orbital Sciences and SpaceX – NASA’s other cargo provider – will compete for follow on ISS cargo delivery contracts.

The next Antares/Cygnus flight is slated for about May 1 from NASA Wallops.

In an upcoming story, I’ll describe Orbital Sciences’ plans to upgrade both Antares and Cygnus to meet the challenges of the ISS today and tomorrow.

Stay tuned here for Ken’s continuing Orbital Sciences, SpaceX, commercial space, Chang’e-3, LADEE, Mars and more news.

A “MiniMoon” Seen Around the World

So, did last night’s Full Wolf Moon seem a bit tinier than usual? It was no illusion, as avid readers of Universe Today know. As we wrote earlier this week, last night’s Full Moon was the most distant for 2014, occurring just a little under three hours after apogee.

Sure, the Moon reaches apogee every lunation, at a distance nearly as far.  In fact, the Moon at apogee can be as far as 406,700 kilometres distant, and last night’s apogee, at 406,536 kilometres, is only the second farthest for 2014. The most distant apogee for 2014 falls on July 28th at 3:28 Universal Time (UT) at just 32 kilometres farther away from our fair planet at 406,568 kilometres distant.

What made last night’s MiniMoon special was its close proximity in time to the instant of Full phase. The July 2014 apogee, for example, will occur just a day and four hours from New phase.

Of course, it isn’t the Moon that’s doing the shrinking, though you’d be surprised the stuff we’ve seen around ye ole Web even on reputable news sites over the past week. The variation of the apparent size of the Full Moon does make for an interesting study in perception. The Moon varies in size from apogee to perigee from about 29.3’ across to 34.1’. This is variation amounts to 14% in apparent diameter.

Here’s an interesting challenge that you can do for a one year period, requiring just a working set of eyes: observe the Full Moon for 12 successive lunations. Can you judge which one was the “SuperMoon” and which one was the “MiniMoon” without prior knowledge?

And as you can see, we also got plenty of pictures here at Universe Today from readers of the Mini-Moon from worldwide.

The rare occurrence of an “Extreme-MiniMoon” — or do you say “Ultra?” — also sparked a lively discussion about the motion of the Moon, how rare this event is, and when it was last and will next be surpassed. A fun online tool to play with is Fourmilab’s Lunar Apogee and Perigee Calculator. Keep in mind, the motion of the Moon is complex, and accuracy for most planetarium programs tends to subside a bit as you look back or forward in time. The distances used in Fourmilab’s calculations are also geocentric, accounting for the center-to-center distance of the Earth-Moon system.

Suffice to say, this year’s Full MiniMoon was the most distant for several decades before 2014 or after.

Anthony Cook of the Griffith Observatory notes that JPL’s Horizons web interface gives a max distance for the Moon of 406,533 kilometres at 1:35 UT earlier today, 3 hours and 19 minutes prior to Full.

The next closest spread of apogee versus perigee occurs on November 18th, 1994 at 1 hour and 51 minutes apart, and 2014’s Mini-Moon won’t be surpassed in this regard until May 13th, 2052. Looking at the distances for the Moon on these dates using Starry Night, however, we get an slightly closer occurrence of 406,345 kilometres for 1994 and 406,246 kilometres for 2052.

And to top it off, the 1994 Mini-Moon was during a partial penumbral eclipse as well… we’ll leave that as a homework assignment for the astute readers of Universe Today to calculate how often THAT occurs. It should be fairly frequent over the span of a century, as the Moon has to be at Full phase for a total lunar eclipse to occur.

Looking over a larger span of time, @blobrana notes on Twitter that closer occurrences of apogee versus Full Moon with the same approximate circumstances as 2014 also occurred on October 29th 817 AD (with a 1 hour and 38 minute difference) and won’t occur again until December 20th, 2154. If research can prove or disprove that these events were even more distant, then the 2014 Extreme MiniMoon was a millennial rarity indeed…

Perhaps this won’t be the last we’ve heard on the subject!

China considers Manned Moon Landing following breakthrough Chang’e-3 mission success

Comparison of China’s Chang’e-3 unmanned lunar lander of 2013 vs. NASA’s Apollo manned lunar landing spacecraft of the 1960?s and 1970?s

Comparison of China’s Chang’e-3 unmanned lunar lander of 2013 vs. NASA’s Apollo manned lunar landing spacecraft of the 1960’s and 1970’s
Story updated[/caption]

Is China’s Chang’e-3 unmanned lunar lander the opening salvo in an ambitious plan by China to land people on the Moon a decade or so hence?

Will China land humans on the Moon before America returns?

It would seem so based on a new report in the People’s Daily- the official paper of the Communist Party of China – as well as the express science goals following on the heels of the enormous breakthrough for Chinese technology demonstrated by the history making Chang’e-3 Mission.

The People’s Daily reports that “Chinese aerospace researchers are working on setting up a lunar base,” based on a recent speech by Zhang Yuhua, deputy general director and deputy general designer of the Chang’e-3 probe system.

No humans have set foot on the moon’s surface since the last US lunar landing mission when Apollo 17 astronauts Gene Cernan and Harrison ‘Jack’ Schmitt departed 41 years ago on Dec. 14, 1972.

For context, the landing gear span of Chang’e-3 is approximately 4.7 meters vs. 9.07 meters for NASA’s Apollo Lunar Module (LM).

When will the US flag return?

Right now China is actively at work on the critical technology required to conduct a manned landing on the Moon, perhaps by the mid-2020’s or later, and scoping out what it would accomplish.

“In addition to manned lunar landing technology, we are also working on the construction of a lunar base, which will be used for new energy development and living space expansion,” said Zhang at a speech at the Shanghai Science Communication Forum. Her speech dealt with what’s next in China’s lunar exploration program.

China’s Yutu lunar rover, deployed by the Chang’e-3 lander, is equipped with a suite of science instruments and a ground penetrating radar aimed at surveying the moon’s geological structure and composition to locate the moon’s natural resources for use by potential future Chinese astronauts.

But the Chinese government hasn’t yet made a firm final decision on sending people to the Moon’s surface.

“The manned lunar landing has not yet secured approval from the national level authorities, but the research and development work is going on,” said Zhang.

Meanwhile the US has absolutely no active plans for a manned lunar landing any time soon.

President Obama cancelled NASA’s manned Constellation “Return to the Moon” program shortly after he assumed office.

And during the 2012 US Presidential campaign, the Republican presidential candidate Mitt Romney famously declared “You’re fired” to anyone who would propose a US manned lunar base.

All that remains of Constellation is the Orion crew module – which was expressly designed to send US astronauts to the Moon and other deep space destinations such as Asteroids and Mars.

NASA hopes to launch a manned Orion capsule atop the new SLS booster on a flight to circle the moon as part of its first crewed mission around 2021 – depending on the budget.

The first Orion capsule will launch on an unmanned Earth orbiting test flight dubbed EFT-1 in mid-September 2014.

However, given the near total lack of reaction from the US political establishment to China’s extremely impressive Chang’e-3 feat and the continuing slashes to NASA’s budget, the outlook for a change in official US Moon policy is certainly not promising.

China and its political leadership – in stark contrast – are clearly thinking long term and has some very practical goals for the proposed lunar base.

“After the future establishment of the lunar base, mankind will conduct energy reconnaissance on the moon, set up industrial and agricultural production bases, make use of the vacuum environment to produce medicines,” Zhang explained according to the People’s Daily.

“I believe that in 100 years, humans will actually be able to live on another planet,” said Zhang.

China also seems interested in international cooperation based on another recent story in the People Daily.

“We are willing to cooperate with all the countries in the world, including the United States and developing countries,” said Xu Dazhe, the new chief of China’s space industry and newly promoted to head the China National Space Administration.

Xu made his remarks at the International Space Exploration Forum held at the US State Department.

However, since 2011, NASA has been banned by official US law from cooperating with China on space projects.

China is wisely taking a step by step approach in its Lunar Exploration programs leading up to the potential manned lunar landing.

With China’s lunar landing architecture now proven by the outstanding success of Chang’e-3, a production line can and has already been set up that will include upgrades potentially leading to the manned mission.

The already approved Chang’e-5 lunar sample return mission is due to liftoff in 2017 and retrieve up to 2 kilograms of pristine rocks and soil from the Moon.

After the completion of the Chang’e-5 mission, the lunar exploration program and the manned space program will be combined to realize a manned lunar landing, Zhang explained according to the People’s Daily.

Meanwhile China is forging ahead with their manned space program. And no one should doubt their resolve.

In 2013 they launched a three person crew to China’s Tiangong-1 space station, reaping valuable technological experience pertinent to manned spaceflight including lunar missions.

By contrast, the US has been forced to rely 100% on the Russian’s to launch American astronauts to the ISS since the forced shutdown of NASA’s space shuttle orbiters in 2011.

China is only the 3rd country in the world to successfully soft land a spacecraft on Earth’s nearest neighbor after the United States and the Soviet Union.

Last night, the Moon and Jupiter snuggled up together in the evening sky, passing within 4°51′ of each other. Folks in Ankara, Turkey got an added benefit to the conjunction, a gorgeous lunar halo. This shot by M. Rasid Tugral is just lovely. The duo stayed together through the night, and you MUST see below for another awesome view of the conjunction at dawn as seen from Pennsylvania in the US:

Chinese Moon Robots Wake up!

China’s history making moon robots – the Chang’e-3 lander and Yutu rover – have just awoken from the forced slumber of survival during their first, long frigid lunar night and have now resumed full operations – marking a major milestone in the mission.

This landmark achievement offers a realistic prognosis that the best is yet to come for this new dynamic duo of robots dispatched from Earth!

The stationary lander and six wheeled rover were autonomously revived from their dormant mode this weekend.

Both were then placed back into full working science mode in response to commands issued by Chinese space engineers at the Beijing Aerospace Control Center (BACC), according to CCTV, China’s official government broadcast network.

Yutu woke up first on Saturday, Jan. 11, at 5:09 a.m. Beijing local time.

The Chang’e-3 lander was awoken on Sunday, Jan. 12, at 8:21 a.m. Beijing local time, according to a BACC statement.

Both vehicles depend on their life giving solar panels to produce power in order to function and accomplish their scientific tasks.

They went to sleep to conserve energy since there is no sunlight to generate power with the solar arrays during the lunar night.

During the nocturnal hiatus they were kept alive by a radioisotopic heat source that kept their delicate computer and electronics subsystems warmed inside a box below the deck. It was maintained at a temperature of about minus 40 degrees Celsius to prevent debilitating damage

The simple fact that both spacecraft survived half a month through the extremely harsh lunar night time environment when temperatures plunged to below minus 180 degrees Celsius, or minus 292 degrees Fahrenheit, and then restarted intact, proves the resiliency and robustness of China’s space technology.

“During the lunar night, the lander and the rover were in a power-off condition and the communication with Earth was also cut off,” said Zhou Jianliang, chief engineer of the BACC, to CCTV.

“When the night ends, they will be started up with the power provided by sunlight and resume operation and communication according to preset programs,” Zhou said.

As night fell on the Earth’s Moon at Christmas time 2013, Yutu and the mother ship lander both entered a state of hibernation – determined to survive the utterly harsh lunar darkness upon the magnificently desolate gray plains.

The mother ship began her nap first on Christmas Day, Dec. 25. Yutu went to sleep on Dec. 26 obeying commands sent by mission control at BACC, according to China’s State Administration of Science, Technology and Industry for National Defence (SASTIND).

Just prior to hibernating, the lander snapped the first image of the Earth taken from the Moon’s surface in some four decades. See below.

Now with the dawn of daylight the solar panels were unfurled and the instruments activated on both robots.

Yutu has already resumed roving towards pristine, unexplored lunar terrain surrounding the touchdown zone at Mare Imbrium, nearby the Bay of Rainbows, or Sinus Iridum region.

After driving in a semicircular path around the right side of the stationary lander, and snapping portraits of one another at 5 preselected locations, Yutu parked some 40 meters south of the mother ship – after touchdown and prior to the start of lunar night.

Yutu, which translates as ‘Jade Rabbit’, is departing the landing zone forever, trekking southwards for surface investigations expected to last at least 3 months – and perhaps longer depending on its robustness in the unforgiving space environment.

The Chang’e-3 lander should survive at least a year.

“They will begin to conduct scientific explorations of the geography and geomorphology of the landing spot and nearby areas, and materials like minerals and elements there,” noted Wu Weiren, chief designer of China Lunar Probe Program.

“We will also explore areas 30 meters and 100 meters beneath the lunar soil. The exploration will continue longer than we planned, because all the instruments and equipments are working very well.”

‘Jade Rabbit’ and the lander will use their suites of science instruments including cameras, telescopes, spectrometers and ground penetrating radar to survey the moon’s geological structure and composition to locate the moon’s natural resources for use by potential future Chinese astronauts.

The robotic pair safely soft landed on the Moon on Dec. 14 at Mare Imbrium, located in the upper left portion of the moon as seen from Earth. Seven hour later on Dec. 15, Yutu rolled all 6 wheels onto the moon’s surface, leaving tracks behind as it cut into the loose regolith.

Presumably they will continue exploring for about the next 14 days – the entire time span of their 2nd Lunar Day, unless they need to take a break from the high daylight temperatures.

Thereafter Yutu and Chang’e-3 will function in alternating cycles of 2 weeks on and 2 weeks off for the duration of their independent working lifetimes.

China is only the 3rd country in the world to successfully soft land a spacecraft on Earth’s nearest neighbor after the United States and the Soviet Union.

Stay tuned here for Ken’s continuing Chang’e-3, Orbital Sciences, SpaceX, commercial space, LADEE, Mars and more news.

See the Smallest Full Moon of 2014: It’s the “Return of the Mini-Moon”

Last month's rising "Mini-Moon" of 2013. (Photo by Author)

 Last month, (and last year) we wrote about the visually smallest Full Moon of 2013. Now, in a followup  act, our natural satellite gives  us an even more dramatic lesson in celestial mechanics with an encore performance just one lunation later with the smallest Full Moon of 2014.

We’ve noted the advent of the yearly Mini-Moon, a bizzaro twin to the often over-hyped “SuperMoon,” or Proxigean Full Moon. Occurring approximately six months apart, you can always expect lunar apogee to roughly coincide with the instant of a Full Moon about half a year after it coincides with perigee. In fact, the familiar synodic period that it takes the Moon to return to like phase (such as Full back to Full) of 29.5 days has a lesser known relative known as the anomalistic month, which is the period of time it takes the Moon to return to perigee at 27.55 days.

But the circumstances for “Mini-Moon 2014” are exceptional. The first Full Moon of the year occurs on the night of January 15th at 11:52 PM EST/4:52 Universal Time (on January 16th). This is just 2 hours and 59 minutes after the Moon reaches apogee at 406,536 kilometres distant at 8:53 PM EST/1:53 UT. This isn’t the farthest apogee that occurs in 2014, but it’s close: the Moon is just 32 kilometres more distant on July 28th, 2014. Apogee can vary from 404,000 to 406,700 kilometres, and this month’s apogee falls just 164 kilometres short of the maximum value.

As you can see, this year’s Mini-Moon falls extremely close to apogee… in fact, you have to go all the way back to the Full Moon of November 18th, 1994 to find a closer occurrence, and this year’s won’t be topped until May 13th, 2052! The Moon will appear only 29’ 23” in size on Wednesday night at moonrise, very close to its minimum possible value of 29’ 18”. This is also almost 5 arc minutes smaller than the largest “Super-Moon” possible.

Cool factoid: you actually move closer to the Moon as it rises, until it transits your local meridian and you begin moving away from it, all due to the Earth’s rotation. You can thus gain and lose a maximum of one Earth radii distance from the Moon in the span one night.

We also just passed the most northern Moon of 2014, as it reached a declination of 19 degrees 24’ north this morning at 8:00 UT/3:00 AM EST. This is a far cry from the maximum that can occur, at just over 28 degrees north. This is because we’re headed towards a “shallow year” as the Moon’s motion bottoms out relative to the ecliptic in 2015 and once again begins to widen out in its 18+ year cycle to its maximum in 2024-25.

This week’s Moon also visits some interesting celestial targets as well. The waxing gibbous Moon sits just 5.1 degrees south of the open cluster M35 tonight. Notice something odd about the Moon’s position Monday night? That’s because it is passing through Orion the Hunter, one of the six non-zodiacal constellations that it can be found in. Can you name the other five? Hint: one was the “13th sign of the zodiac that created a non-traversy a few years back.

On Tuesday evening, the Moon passes six degrees from the planet Jupiter. This presents a fine time to try and spot the planet in the daytime to the Moon’s upper left, just a few hours prior to sunset.

The Moon will also occult the +3.6 magnitude star Lambda Geminorum on January 15th for observers in northwestern North America. In fact, viewers along a line crossing central British Columbia will witness a spectacular graze along the lunar limb as the star winks out behind lunar mountains and pops into view as it shines through lunar valleys along the edge of the Moon. This can make for an amazing video capture, we’re just throwing that out there…

In addition to being this year’s Mini-Moon, the January Full Moon is also known as the Wolf Moon in the tradition of the Algonquin Native Americans, as January was a time of the mid-winter season when starving wolf packs would howl through the long cold night. The January Full Moon is also sometimes referred to as “The Moon after Yule,” marking the first Full Moon after Christmas.

And just when is the next Super Moon, you might ask? Well, 2014 has three Full Moons occurring within 24 hours of perigee starting on July 15th and finishing up on September 8th. But the most notable is on August 10th, when the Moon passes perigee just 27 minutes from Full. Expect it to be preceded by the usual lunacy that surrounds each annual “Super Moon” as we once again bravely battle the forces of woo and describe just exactly what a perigee Full Moon isn’t capable of. Yes, we still prefer the quixotic term “Proxigean Moon,” but there you go.

Also, be sure to wave a China’s Chang’e-3 lander and rover in the Bay of Rainbows (Sinus Iridum) as you check out this week’s Full Moon, as it just experienced its first lunar sunrise this past week.
