Posted by Nick Azer in : Constellation, LCROSS, Lunar Reconaissance Orbiter, NASA , 1 comment so far
NASA’s twin lunar orbiter craft—the Lunar Reconnaissance Orbiter (LRO) and the Lunar CRater Observation and Sensing Satellite (LCROSS)—were successfully launched on Thursday aboard an Atlas V rocket.
This marks the first mission (well, missions) in Constellation to be launched, the beginning of a big new era for NASA (“America’s first step in a lasting return to the Moon”, as the launch video embedded below declares it.)
The LRO will aim it’s seven instruments (which I’ll be taking individual looks at here at Luna C/I) at the Moon to collect detailed information about its environment, in preparation for colonization (and potentially mining) efforts,;while the LCROSS is designed to use one of its rocket phases to create an impact in a deep-shadow crater, analyzing the material to see if there is water ice present there—a potentially “smashing success“.
Embedded below is a pretty spectacular video from NASA of the launch, from on board the rocket itself (check out the SpaceX Falcon 1 launch video for a similar, if even more astounding, view of a rapid departure from Earth) :
NASA's Dual LRO and LCROSS Mission Launches Coming Up Soon—June 17th! May 25, 2009

An exciting step for NASA is coming up fast: the combined launch of the Lunar Reconnaissance Orbiter (LRO; pictured above) and the Lunar CRater Observation and Sensing Satellite (LCROSS; pictured below) is set for June 17th.
The two craft will orbit the moon, with the LRO taking measurements of potential environmental hazards, such as radiation and lunar dust (specifically, areas where the dust will be extra-charged and therefore even more of a nuisance than usual), and with the LCROSS creating an impact in a deep-shadow crater and studying the resulting plume to see if there’s potential water ice.
As the missions get underway, I’m going to be rolling out a lot of features here at Luna C/I covering many aspects of the craft, and the work they are looking to do. Should be exciting times (and a big PR time for Constellation), so save that date, and keep an eye out for updates and detailed looks to be beginning here soon :)
Chandrayaan-1 Payload Feature #4: Radiation Dose Monitor Experiment (RADOM) December 8, 2008
Posted by Nick Azer in : Bulgaria, Chandrayaan-1, Chandrayaan-1 Payload Features, Indian Space Research Organization, Lunar Reconaissance Orbiter, NASA, radiation , add a commentToday is the fourth in a series of features on each of the Indian lunar orbiter Chandrayaan-1′s scientific payloads. The Chandrayaan-1 has 11 scientific instruments onboard to complete an array of measurements: five Indian instruments, and six from other nations and organizations (including the ESA and NASA).
For this edition, we look at the Radiation Dose Monitor Experiment, or RADOM, which is from the Bulgarian Academy of Sciences.
Radiation Dose Monitor Experiment (RADOM)
The RADOM is essentially looking to get results (like those pictured above) on just how much radiation there is in lunar orbit and around the surface, so future moon missions have a clearer image if just how much radiation protection is needed.
Radiation is a serious problem for potential colonists, and as that article notes, NASA is including radiation experiments in its own lunar orbiter mission, the LRO (coming next year).
“”We really need to know more about the radiation environment on the Moon, especially if people will be staying there for more than just a few days,” says Harlan Spence, a professor of astronomy at Boston University.”
-“Radioactive Moon”, by Patrick L. Barry, NASA
The Apollo astronauts were never out in the radiation for long, so creative solutions are needed to shield long-term settlement. But, first, it needs to be known just how much radiation there is to shield from; and the RADOM is a big step towards that.
For all the full scientific details on the payload straight from the Bulgarians, check out this document. :)

Chandrayaan-1 Payload Spotlight #1: Terrain Mapping Camera (TMC) November 9, 2008
Posted by Nick Azer in : Chandrayaan-1, Chandrayaan-1 Payload Features, Chang'e, European Space Agency, Indian Space Research Organization, Kaguya, Lunar Reconaissance Orbiter, NASA, selenography , add a commentToday is the first in a series of features on each of India‘s recently-launched Chandrayaan-1‘s scientific payloads.
As I cover each of the eleven payloads in individual posts over the next few weeks, I’m going to alternate between the Indian and foreign payloads.Without further ado, here’s your spotlight on the Terrain Mapping Camera (TMC).
Terrain Mapping Camera
An Indian instrument, the first payload being featured here was also the first one to be tested.
It’s mostly as it sounds: a high-resolution camera that can take black and white photographs of the lunar surface (with a 5m spatial resolution–”the ability to distinguish between two closely spaced objects on an image“–in 20km swaths[PDF] ), with the intent to map the entire topography of the moon (including the dark side and the poles) at that 5m resolution; creating the most high-resolution, detailed map of the lunar surface to date. Such maps exist of Mars, but not of the Moon.
NASA’s Lunar Reconaissance Orbiter (LRO) mission set for next year will have similar, if more powerful, camera and mapping systems. These kinds of maps will clearly be useful for the planning stages of the eventual lunar colonies and for other efforts.
The power of the TMC could well be enough to finally settle one thing for NASA ahead of time, though: it could photograph the Apollo and other NASA craft on the Moon’s surface, hopefully putting all those conspiracy theories to rest. :)
Here’s a picture from the ISRO of the TMC itself:
And, last but not least, one of the test images the camera took of Earth (high resolution here):
For every technical detail you ever wanted to know about the TMC, see this PDF.
Check back within the next couple of days for the next feature, on one of the Chandrayaan-1′s foreign payloads, as well as for any other updates on the moon mission’s progress that may come along :)
Picture of the Week: Peek-A-Boo August 8, 2008

That is a picture of a Lunar Reconnaissance Orbiter (LRO) mockup, with the Narrow Angle Camera being looked at by a team member identified as ‘Cathy’ (which, looking at the team’s members, is probably the Deputy Project Manager Catherine Peddie).
The LRO is the first major mission of the Vision for Space Exploration era of NASA, with an expected launch of February 27, 2009. It’s mission is largely one of documentation, with a more in-depth look at the selenology and selenodesy of the moon in preparation for the set-up of colonies there before 2030 or so. In addition to what will assuredly be lots of neat, pretty pictures, the LRO will send back valuable information about radiation, water, and other key environmental elements that may or may not be present on the moon.

One concern that gets voiced about lunar colonization is the levels of radiation colonists could be exposed to, and how much of a threat that is (and whether there is sufficient methods of protection against it).
“We really need to know more about the radiation environment on the Moon, especially if people will be staying there for more than just a few days.”
-Harlan Spence, astronomy professor at Boston University
Mapping out and investigating the levels of radiation is one the central goals of NASA’s Lunar Reconnaissance Orbiter (LRO) mission, the first tentpole mission of the landmark Vision for Space Exploration/Constellation era.
Various remedies and shields have been suggested, including isolated magnetic fields (like Reiner Gamma, pictured above; these are speculated to be a result of crater- and other ejecta), spherical man-made shields (pictured below), and even the Earth itself.
I personally trust in human ingenuity to come up with something, and the lack of effects on the Apollo astronauts seems promising (though many seem to think that indicates the whole Apollo landing was actually a hoax). At the very least, the commercial motivation for a company to come up with something that could enable colonization (and therefore utilization of groundbreaking resources) could eventually (or very quickly) become too strong to be ignored.
To cap, here’s a segment on the subject from a NASA video (Destination Tomorrow), courtesy of Youtube:
A Phoenix + Ice = ? May 28, 2008
Posted by Nick Azer in : areology, Lunar Prospector, Lunar Reconaissance Orbiter, Lunar Research Institute, Mars, Phoenix lander, Polar ice , add a commentThree days ago (May 25th), NASA’s Phoenix lander made it safely to the surface of Mars; specifically, the north polar region (where water ice was discovered to be chillin’ back in 2005).
Like the features of the Moon, the north polar region of Mars has a Latin name: Planeum Borem (insert “Bore ‘em” joke/pun here), which means simply ‘The Northern Plain”. Below is a mosaic of this northern region from, appropiately enough, the Viking spacecraft:
You’re probably thinking “Yeah, NASA and all, but what’s this got to do with colonization of the Moon?”
Well, as far as having water at the poles, Mars may have company. The key word, though, seems to be “may“: efforts such as NASA’s Lunar Prospector and Europe’s SMART-1 have not turned up any clear evidence. Third time may be the charm, though (or at least that’s NASA’s idea): the Lunar Reconaissance Orbiter (LRO; launching November 24th, 2008) has a primary goal of finding water, along with even more critical research regarding lunar landing sites and radiation study.
As that Space.com AP article above notes, though:
“…the only way to know for sure is to send a human or robot. ‘You’ve got to go down and stick your finger in it, so to speak,’ he [Alan Binder, the director of the Lunar Research Institute] said.”
With Mars, that obviously seems to be their plan. While Mars has the possibility of past life tied to its water, the main motivation to discover water on the Moon is to plan for the possibility of future life (though water could simply be imported, especially if a space elevator is around to reduce the cost of getting it off Earth).
As the 6-month Phoenix surface mission unfolds, it should be interesting to see what lessons can be gleaned from it for similar poking around on the Moon.
