Did a microbe survive 2.5 years attached to Surveyor 3 on the Moon, and then come home on Apollo 12? New research says no.
Confirmed: one of two tickets for a lunar flyby on a Soyuz has been sold. More here.
Software engineers to the Moon!
Crazy? Absolutely! Impossible? Probably not! There are a growing number of people who believe that with federal funding for our space program getting scarce, the future lies in private-public partnerships. Entrepreneur Elon Musk’s third job (after leading electric car company Tesla and acting as the Chairman of solar installer SolarCity) is heading up SpaceX, which was the first private company to successfully launch, orbit and recover a rocketship. Virgin’s Richard Branson has a similar private space venture.
The Lunar Reconnaissance Orbiter website recently announced a new way to tour the Moon. The website, called QuickMap, allows a user with any home computer to zoom into any spot on the lunar surface and see the high resolution images being taken by Lunar Reconnaissance Orbiter.
Using QuickMap, I spent a few hours this past weekend strolling about on the northern half of the floor of the crater Copernicus. It is in this area, annotated in the image on the right, that NASA engineer James Fincannon has already located a slew of collapse features and possible caves, the images of which I have posted previously on behindtheblack. (Click on the image or here to see a larger version of this updated index map.)
(You also can go sightseeing there if you wish. Go to QuickMap and zoom in on 10.1 latitude and -20.1 longitude to get to the floor of Copernicus. Or pick your own spot on the lunar surface and do some of your own exploring!)
What I found in the northern half of Copernicus’s floor was a plethora of possible caves and collapse features. Literally, the crater floor is littered with what appear to be pits, fissures, rills, and sinks. More significantly, sometimes the cave entrances line up with long straight collapse features, suggesting strongly the existence of extensive underground passages beyond the initial entrance pits.

China’s second lunar orbiter, Chang’e 2: still in operation after 180 days.
Unfortunately, little of its scientific results have been released.
No, the “supermoon” didn’t cause the Japanese earthquake.
29 teams, one purchased ride, and one mystery for the Google Lunar X Prize.
The discovery of new caves on the Moon keep coming. Today I have two new stories. The first is a discovery by professional scientists of a giant lava tube cave in the Oceanus Procellarum or Ocean of Storms. The second is the detection of a plethora of caves and sinks on the floor of the crater Copernicus, found by a NASA engineer who likes to explore the gobs of data being accumulated by Lunar Reconnaissance Orbiter and made available to all on the web.
The image below of the Moon’s near side, taken by India’s Cartosat-2A satellite and taken from the science paper, shows the location of lava tube in Oceanus Procellarum (indicated by the red dot) and the crater Copernicus.
First the professional discovery. Yesterday, the Times of India reported the discovery of lava tube more than a mile long on the Moon. I did not post a link to the article because I didn’t think the news story provided enough information to make it worth passing along. Today however, fellow caver Mark Minton emailed me the link where the actual research paper could be downloaded [pdf]. This I find definitely worth describing.

The Google Lunar X Prize has announced the final roster of teams competing for its $30 Million prize.
We need to find them! Trees from space, planted here on Earth. You can see the known list here.
More images of lunar cave pits have been posted by the scientists of Lunar Reconnaissance Orbiter (LRO). They have also published their first paper [pdf] about these cave pits for the 2011 Lunar and Planetary Science Conference taking place in March. The paper summarizes, with images, what is know about the three pits on the Moon that have each been imaged a number of times at different angles and lighting situations.
One of the competitor’s for the Google Lunar X prize has signed a contract with SpaceX to use the Falcon 9 to get its spacecraft to the Moon. Key quote:
The Falcon 9 upper stage will sling Astrobotic on a four-day cruise to the Moon. Astrobotic will then orbit the moon to align for landing. The spacecraft will land softly, precisely and safely using technologies pioneered by Carnegie Mellon University for guiding autonomous cars. The rover will explore for three months, operate continuously during the lunar days, and hibernate through the lunar nights. The lander will sustain payload operations with generous power and communications.
If you’re interested, seats are available for a tourist trip around the moon in a Soyuz capsule. And the Russians say the Soyuz is ready to go!
An Israeli team has entered the Google Lunar X Prize competition, hoping to land a nanosat on the moon for only $8 million.
Keith Cowing is trying to locate a missing spectacular blow-up poster of the Lunar Orbiter “Earthrise” image from 1966, shown here.
The early Lunar Orbiter images, taken in the mid-1960s, have been reprocessed and recovered, in a spectacular manner.
Using old Apollo data, scientists have detected the Moon’s molten core.
Amateur astronomer Thierry Legault traveled to Oman to not only photograph the Moon as it eclipsed the Sun on January 4, but also capture the International Space Station at the same moment. The image he took of both as they crossed in front of the Sun is amazing.
An evening pause: The Christmas eve telecast by the Apollo 8 astronauts from lunar orbit, December 24, 1968, probably the most listened to space telecast in history. The story behind how and why these men said what they did is the central theme of my first book, Genesis, the Story of Apollo 8.
NASA engineer James Fincannon emailed me the image below, cropped from this Lunar Reconnaissance Orbiter scan. It shows a side view of the same lunar pit previously discussed by me in July (here and here).
This image below was almost certainly ordered up by LRO scientists after seeing the images above so that they could get a look at the pit’s walls. I have further cropped it and blown it up so we can get a really good look too! See the second image below.
In this side view, we are looking across the top of the pit at the far wall and floor. On that far wall you can see what look like three coarse horizontal layers, below which is a deeply shadowed floor layer that is probably either cave passage or a significant overhang. Further processing will probably be bring out some further details and hopefully answer this question.
In a previous post, I had noted that this wall is probably about 200 feet deep. This new image thus gives any experienced rock-climber or caver a very nice sense of what a rappel down the side of that pit would be like. To me, it reminds me of some of the open-air cave pits I’ve rappelled into in New Mexico.
Update: I should note that that overhang/cave entrance at the bottom of the pit is probably at least 30 feet high. An impressive entrance, indeed.
Also, lunar scientist Paul Spudis emailed me with these comments:
[The pit] is very similar to some tube systems that I have studied in Hawaii. The wall units are exposed lava flows. They are probably all from the event which made this flow — a single flow can be made up of multiple flow units, hence, the apparent “layering.”
Of course, getting into an open pit and then moving through open void lava tubes that radiate from it are two different things. In terrestrial tube systems, many tubes are open and accessible but sometimes they are not. They can be blocked up by frozen lava or rubble from adjacent tube collapse.
Unfortunately, I don’t think we’re going to know what the situation on the Moon is until we get there. However, I must say, this particular area looks very promising.
The image below was produced by Lunar Reconnaissance Orbiter by assembling data from numerous images over six months. The levels of brightness and darkness indicate the percentage of time in which an area is sunlight. The red dot just below the rim of Shackleton shows the approximate location of the south pole.
As you can see, the rim of Shackleton Crater nearest the south pole is illuminated by the sun most of the time, while the nearby crater floor never gets sunlight. This data confirms what Japanese scientists found using their lunar probe, Kaguya. The south pole has the ideal combination of locations with nearly continuous bright sunlight (to provide power) and nearly continuous darkness (where explorers will likely find significant amounts of frozen water), making this is an excellent location to build that first lunar base. And from the image you can see that the Shackleton Crater rim is not the only spot near the south pole with these conditions.
Also, if you look at the close-up image of Shackleton’s rim that I posted here, you will see that there is plenty of room to land and set up residence.
