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.

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.

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

NASA’s long-lived Opportunity Mars rover has accomplished what absolutely no one expected.

Opportunity is about to embark on her 2nd decade exploring the Red Planet since her nail biting touchdown in 2004.

And to top that off she is marking that miraculous milestone at a spectacular outlook by the summit of the first mountain she has ever scaled!

See our Solander Point summit mosaic showing the robots current panoramic view – in essence this is what her eyes see today; above and below.

And that mountaintop is riven with outcrops of minerals that likely formed in flowing liquid neutral water conducive to life – potentially a scientific goldmine.

“We expect we will reach some of the oldest rocks we have seen with this rover — a glimpse back into the ancient past of Mars,” says the rover principal investigator, Steve Squyres of Cornell University, Ithaca, N.Y.

“It’s like starting a whole new mission.”

Back on sol 3365 we took this image of Solander Point as we approached it. Here I have plotted the subsequent route that Opportunity has taken in climbing up the ridge. The outcrop shown I the images below are near the end of the yellow traverse line.  Caption and mosaic by Larry Crumpler/NASA/JPL/

Opportunity is nearly at the peak of Solander Point, an eroded segment on the western flank of vast Endeavour Crater, that spans some 22 kilometers (14 miles) in diameter.

The six wheeled rover reached the top section of Solander on Sol 3512, just before Christmas in December 2013. It’s situated nearly 40 meters (130 feet) above the crater plains.

There she began inspecting and analyzing an area of exposed outcrops called ‘Cape Darby’ that scientists believe holds caches of clay minerals which form in drinkable water and would constitute a habitable zone.

The science team directed Opportunity to ‘Cape Darby’ based on predictions from spectral observations collected from the CRISM spectrometer aboard one of NASA’s spacecraft circling overhead the Red Planet – the powerful Mars Reconnaissance Orbiter (MRO).

Opportunity is using all its cameras and instruments as well as those on the robotic arm to inspect the outcrop area, including the rock abrasion tool, spectrometers and microscopic imager.

As reported earlier this week, the rover is also investigating a mysterious rock that suddenly appeared in images nearby the robot. ‘Pinnacle Island’ rock may have been flung up by the wheels. No one knows for sure – yet.

Solander Point is the first mountain she has ever climbed along her epic 10 year journey across the plains of Meridiani. Heretofore she toured a string of Martian craters. See 10 Years Route map below.

In mid-2013, the scientists used similar orbital observations to find a rock called “Esperance’ – which was loaded with clay minerals and located along another Endeavour crater rim segment called Cape York.

Squyres ranked “Esperance” as one of the “Top 5 discoveries of the mission.”

The team hopes for similar mineralogical discoveries at Solander.

The northward-facing slopes at Solander also afford another major benefit to Opportunity. They will tilt the rover’s solar panels toward the sun in the southern-hemisphere winter sky thereby providing an important energy boost.

The power boost will enable continued mobile operations through the upcoming frigidly harsh winter- her 6th since landing 10 years ago.

So Opportunity will be moving from outcrop to outcrop around the summit during the Martian winter. Daily sunshine reaches a minimum in February 2014.

As of Wednesday, Jan. 15, 2014, or Sol 3547, the solar array energy production on the rover is 353 watt-hours, compared to 900 watt-hours after landing. But that is sufficient to keep moving and actively conduct research throughout the winter at the mountaintop.

Opportunity’s long and winding road on the Red Planet began when she safely settled upon the alien world on 24 January 2004, following a harrowing plummet through the thin Martian atmosphere and an airbag assisted, bouncing ball landing.

She arrived barely 3 weeks after her twin sister, Spirit on 3 January 2004.

Today marks Opportunity’s 3551st Sol or Martian Day roving Mars – for what was expected to be only a 90 Sol mission.

So far she has snapped over 188,100 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 24.07 miles (38.73 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Read more about sister Spirit – here and here.

Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp. She celebrated 500 Sols on Mars on New Years Day 2014.

And a pair of new orbiters are streaking to the Red Planet to fortify the Terran fleet- NASA’s MAVEN and India’s MOM.

Finally, China’s Yutu rover is trundling across pitted moonscapes.

Stay tuned here for Ken’s continuing Opportunity, Curiosity, Chang’e-3, LADEE, MAVEN, Mars rover and MOM news.

Wake Up, Rosetta!

It’s being called “the most important alarm clock in the Solar System” —  this Monday, January 20, at 10:00 GMT (which is 5:00 a.m. for U.S. East Coasters like me) the wake-up call will ring on ESA’s Rosetta spacecraft, bringing it out of hibernation after over two and a half years in preparation of its upcoming and highly-anticipated rendezvous with a comet.

The wake-up will incite the warming of Rosetta’s star trackers, which allow it to determine its orientation in space. Six hours later its thrusters will fire to stop its slow rotation and ensure that its solar arrays are receiving the right amount of sunlight. Using its thawed-out star trackers Rosetta will aim its transmitter towards Earth and, from 500 million miles (807 million km) away, will send a thumbs-up signal that everything is OK and it’s time to get back to work.

From that distance the transmission will take 45 minutes to reach us. Rosetta’s first signal is expected between 17:30 – 18:30 GMT (12:30 – 1:30 p.m. ET). Once we’re assured all is well, Rosetta has a very exciting year ahead!

After nearly a decade of soaring through the inner solar system, flying past Mars and Earth several times and even briefly visiting a couple of asteroids (2867 Steins on September 5, 2008 and 21 Lutetia on July 10, 2010) Rosetta is finally entering the home stretch of its mission to orbit the 4-km-wide comet 67P/Churyumov-Gerasimenko.

Once Rosetta enters orbit around the comet — the first time a spacecraft has ever done so — it will map its surface and, three months later in November, deploy the 220-lb (100-kg) Philae lander that will intimately investigate the surface of the nucleus using a suite of advanced science instruments. (Watch a video here of how all this will happen… using Legos!)

With Philae firmly attached to the comet, Rosetta will follow it around the Sun as it makes its closest pass in August 2015 and then heads back out towards the orbit of Jupiter. Rosetta will provide the most detailed observations ever of a comet’s composition and dramatic evolution as it encounters the heat and energy of our home star.

Of course, before all this can happen Rosetta first has to… WAKE UP! It entered hibernation in July 2011 and has remained silent in a slow spin ever since, with only its computer and some heaters kept running. Waking up from a 31-month nap can’t be easy, so ESA is inviting people around the world to help Wake Up Rosetta (and possibly even win a trip to Germany for the landing in November) by sharing their short movies of how best to awaken a sleeping spacecraft and sharing them to the contest page on Facebook or to Twitter, Vine, or Instagram with the #WakeUpRosetta hashtag.

See more about the contest below:

Video submissions to the Wake Up Rosetta video contest will be accepted until 17:30 GMT on Monday so if you haven’t already, get your cameras out and your imaginations going… this spacecraft isn’t going to wake itself! (Well, actually it kinda is but you can still show off your creativity!)

And even if you don’t send in a video, you can watch the live feed of Monday’s events from ESA starting at 09:15 GMT (4:15 a.m. ET) here and here. (Also follow @ESA_Rosetta on Twitter — currently it’s “still sleeping.”)

Want to find out where Rosetta is right now? Check out this cool interactive map from Daniel Scuka, Senior Editor of Spacecraft Operations at ESOC.

Rosetta launched on March 2, 2004 by an Ariane-5 G+ from Europe’s spaceport in Kourou, French Guiana. Read more on the mission page and the Rosetta blog here.

___________

UPDATE Jan. 20: Rosetta has awoken! This afternoon at 18:18 UTC, after 48 minutes of increasingly tense anticipation, a signal from the spacecraft was received by both NASA’s Deep Space Network in Goldstone, CA and the ground station in Canberra, Australia. Rosetta is up and running and so far seems to be in good condition — Go Rosetta and Philae! Read the full story here.

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?

Enduring Quests and Daring Visions: NASA Lays Out a Roadmap for Astrophysics

An artist's concept of Kepler-69c, a super-Earth in the habitable zone of a sun-like star.

Three decades ago we were unaware that exoplanets circled other stars. We had just started talking about dark matter but remained blissfully ignorant of dark energy. The Hubble Space Telescope was still on the drawing board and our understanding of the life cycle of stars, the evolution of galaxies, and the history of the Universe was shaky.

But over the past three decades we have discovered thousands of exoplanets around other stars. We have mapped the life cycle of stars from their formation in beautiful stellar nurseries to their sometimes explosive deaths. We have seen deep into the history of the Universe allowing us to paint a picture of galaxies growing from mere shreds to the incredible spiral structures we see today. We now believe dark matter dominates the underlying framework of the Universe, while dark energy drives its accelerating expansion.

The amount of growth over the past three decades has been dramatic. To better access what the next three decades will bring, NASA has laid out a roadmap — a long-term vision for future missions — necessary to advance our understanding of the Universe.

In March 2013, the NASA Advisory Council/Science Committee assembled a group of astronomers who would determine the goals and aims of NASA for the next 30 years. The final product is this so-called roadmap officially titled “Enduring Quests Daring Visions — NASA Astrophysics in the Next Three Decades.”

The roadmap first notes three defining questions NASA should continue to pursue:
— Are we alone?
— How did we get here?
— How does the Universe work?

“Seeking answers to these age-old questions are enduring quests of humankind,” the roadmap states. “The coming decades will see giant strides forward in finding earthlike habitable worlds, in understanding the history of star and galaxy formation and evolution, and in teasing out the fundamental physics of the cosmos.”

In order to better address these questions, the roadmap defines three broad categories of time: the Near-Term Era, defined by missions that are currently flying or planned for this coming decade, the Formative Era, defined by missions that are designed and built in the 2020s, and the Visionary Era, defined by advanced missions for the 2030s and beyond.

Are we alone?

The Near-Term Era’s goal is to develop a comprehensive understanding of the demographics of planetary systems. The Kepler mission has already supplied a plethora of information on hot planets orbiting close to their parent stars. The WFIRST-AFTA mission — a wide-field infrared survey planned to launch in 2024 — will compliment this by supplying information on cold and free-floating planets.

The Formative Era’s goal is to characterize the surfaces and atmospheres of nearby stars. This will allow us to move beyond characterizing planets as Earth-like in mass and radius to truly being Earth-like in planetary and atmospheric composition. A proposed mission that allows a large star-planet contrast will directly measure oxygen, water vapor, and other molecules in the atmospheres of Earth-like exoplanets.

The Visionary Era’s goal is to produce the first resolved images of Earth-like planets around other stars. The roadmap team hopes to identify continents and oceans on distant worlds using optical telescopes orbiting hundreds of kilometers apart.

How did we get here?

The Near-Term Era will use the James Webb Space Telescope to supply unprecedented views of protostars and star clusters. It will resolve nearby stellar nurseries and take a closer look at the earliest galaxies.

The Formative Era will trace the origins of planets, stars and galaxies across a spectrum of wavelengths. An infrared surveyor will resolve protoplanetary disks while an X-ray surveyor will observe supernova remnants and trace how these incredible explosions affected the evolution of galaxies. Gravitational wave detectors will untangle the complicated dance between galaxies and the supermassive black holes at their centers.

The Visionary Era will peer nearly 14 billion years into the past when ultraviolet photons from the first generation of stars and black holes flooded spaced with enough energy to free electrons. The James Webb Space Telescope will provide an extraordinary means to better view this threshold.

How does the Universe work?

The Universe is full of extremes. Conditions created in the first nanoseconds of cosmic time and near the event horizons of black holes cannot be recreated in the lab. But the Near-Term and Formative Era’s goals will be to measure the cosmos with such precision that scientists can probe the underlying physics of cosmic inflation and determine the exact mechanisms driving today’s accelerating expansion.

The Visionary Era may use gravitational wave detectors to detect space-time ripples produced during the early stages of the Universe or map the shadow cast by a black hole’s event horizon.

The past 30 years have shown a dramatic growth in knowledge with unimaginable turns. Even with such a detailed framework laid out for the next 30 years, it’s likely that many missions are currently beyond the edge of the present imagination. The most exciting results will be drawn from the questions we haven’t even thought to ask yet.

And as with any of the recent “roadmaps” that the various divisions throughout NASA have presented, the biggest question will be if the funding will be available to make these missions a reality.

Again, this 110-page read may be found here.

The roadmap team consists of Chryssa Kouveliotou (NASA/MSFC), Eric Agol (University of Washington), Natalie Batalha (NASA/Ames), Jacob Bean (University of Chicago), Misty Bentz (Georgia State University), Neil Cornish (Montana State University), Alan Dressler (The Observatories of the Carnegie Institution for Science), Scott Gaudi (Ohio State University), Olivier Guyon (University of Arizona/Subaru Telescope), Dieter Hartmann (Clemson University), Enectali Figueroa-Feliciano (MIT), Jason Kalirai (STScI/Johns Hopkins University), Michael Niemack (Cornell University), Feryal Ozel (University of Arizona), Christopher Reynolds (University of Maryland), Aki Roberge (NASA/GSFC), Kartik Sheth (National Radio Astronomy Observatory/University of Virginia), Amber Straughn (NASA/GSFC), David Weinberg (Ohio State University), Jonas Zmuidzinas (Caltech/JPL), Brad Peterson (Ohio State University) and Joan Centrella (NASA Headquarters).

The Rock that Appeared Out of Nowhere on Mars

Screenshot from Steve Squyres presentation celebrating 10 years of the Mars Exploration Rovers. A rock suddenly appeared where there was none 12 sols earlier.

During last night’s celebration at the Jet Propulsion Laboratory of ten years of the Mars Exploration Rovers, mission principal investigator Steve Squyres shared several stories about the exploration and discoveries made by the rovers Spirit and Opportunity since they landed on Mars in 2004. An intriguing recent mystery is a strange rock that suddenly appeared in photos from the Opportunity rover in a spot where photos taken just 12 sols earlier showed no rock.

“One of the things I like to say is that Mars keeps throwing new things at us,” Squyres deadpanned.

Squyres described the rock as “white around the outside, in the middle there’s low spot that is dark red. It looks like a jelly donut,” he said. “And it appeared. It just plain appeared and we haven’t driven over that spot.”

They’ve named it “Pinnacle Island,” and the team is contemplating a few ideas of why the rock mysteriously showed up.

“One theory is that we somehow flicked it with a wheel,” Squyres said. “We had driven a meter or two away from here and somehow maybe one of the wheels managed spit it out of the ground. That’s the more likely theory.”

The other?

“The other theory is that there might be a smoking hole in the ground nearby and this may be crater ejecta. But that one is less likely,” Squyres said.

Another idea suggested by others is that it may have tumbled down from a nearby rock outcrop.

But as intriguing as the sudden appearance of the rock is what the team is finding out about it.

“We are as we speak situated with the rover, with its instruments, making measurements on this rock. We’ve taken pictures of both the donut part and the jelly part,” Squyres said. “The jelly part is like nothing we’ve seen before on Mars. It’s very high in sulfur and magnesium and it has twice as much manganese as anything we’ve seen before. I don’t know what any of this means. We’re completely confused, everybody on the team is arguing and fighting. We’re having a wonderful time!”

But that’s the beauty of this mission, Squyres said.

“I used to have this comforting notion that at some point, we could sit back and say ‘we did it, we’re finished, we’ve learned everything we could about this location.’ But Mars is not like that. It keeps throwing new things at us.”

“And what I’ve come to realize,” Squyres concluded, ” – and it was true when we lost Spirit and it will be true when we lose Opportunity — there will always be something tantalizing just beyond our reach that we just won’t get to. That’s just the nature of exploration, and I feel so very fortunate to have been part of this mission.”

Due to gravity, most objects in space are spherical — whether it’s round planets and stars or swirling spiral galaxies. That’s why this object, the Red Rectangle Nebula, or HD 44179, is so intriguing.

“The overall shape of the nebula is a puzzle for astronomers to figure out,” said astronomer Adam Block from the Mount Lemmon SkyCenter at the University of Arizona, via email. “The leading theory suggests that bipolar, cone-shaped, and periodic outflows, when viewed in profile as we do, may give the shape we see. The intense red color still remains a bit of a mystery.”

From most “smaller” ground based telescopes, this object really does look like a rectangle, but images from space, such as from the Hubble Space Telescope, reveal that rather than being rectangular, is shaped like an X with additional complex structures of spaced lines of glowing gas, a little like the rungs of a ladder. This stunning new image from Adam also captures these features.

He said he wanted to know what it really looked like from a ground-based telescope using full color (broad band) filters.

“I didn’t know, but now I do,” Adam said. “It is a tiny tiny thing; but it was wonderful to see it develop from the raw data to this rendered result. The central star is very bright and nearly overwhelms the interesting parts of the nebula. In addition to its size, the central star is a big challenge to tame.”

Compare the Space Station’s Internet Speed with Yours

We now take it for granted that astronauts on the International Space Station can tweet and post things on Facebook and G+ live from space, but it wasn’t always so. Before January of 2010, any emails, news, or Twitter messages were sent to and from the ISS in uplink and downlink packages, so for example, Twitter messages from the astronauts were downlinked to mission control in Houston, and someone there posted them on the astronauts’ Twitter accounts. But now they have “live” internet. However, as you can imagine, there are no fiberoptic cables hooking up to the ISS, so the internet speeds aren’t blazing fast.
