Chandrayaan-1 Payload Feature #4: Radiation Dose Monitor Experiment (RADOM)

Today 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."

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.

India Launches Chandrayaan 1 Moon Mission (News)

Today, India's Indian Space Research Organisation (ISRO) successfully launched it's first lunar mission, the Chandrayaan 1.

An unmanned lunar explorer (a la Japan's Kaguya), the Chandrayaan-1 (which is "moon craft" in Sanskrit) is set to map lunar topography in 3D, creating (as the ISRO puts it) a "3D atlas" and notably, chemical mapping of the lunar surface.

While I haven't found any specific references to helium-3 in any Indian or other documentation of the Chandrayaan project, that prominent "chemical mapping" goal suggests that, like Russia, China, NASA, and others, India is seriously interested in the resource potential of the Moon.

The craft is carrying scientific payloads for six other organizations (check that link for specific pages for each one), including NASA, Europe's ESA, and Bulgaria's Space Research Institute.

This story got some big media play in the form of a huge front-page Drudge Report splash, with a huge picture of the Moon in the place usually reserved for the likes of Obama and McCain. Here's that spectacular image (which ran with an "INDIA TO THE MOON!" headline):

I'm a little surprised at the high-profile coverage, as this Indian mission isn't a whole lot different than JAXA's, which didn't appear to get quite the same sort of media push. I think this speaks to the sort of excitement the Base Race can generate, especially as the significant 2010-2020 decade pulls closer (and as things domestically get more and more grim in the meantime).

The Chandrayaan-1 mission is expected to last for two years, with Chandrayaan-2, a joint Indo-Russian moon rover venture, shooting for 2011.
