Will humans follow?

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 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 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 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 navigation camera – which we assembled from screenshots taken as it as 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.

 

 

Chang'e 3 Lander Beams Back New Lunar Panorama Photos

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?
