The HAND, a gauge of Russian design and manufacture at the USA’s Mars Odysseus station, discovered water ice on Mars back in March 2002, expert Igor Mitrofanov said to Novosti. Laboratory head at the Space Research Institute under the Russian Academy of Sciences, he led HAND design and a related experiment. Neutron flows from Mars have been mapped by now. The available global maps have a resolving power of 200 to 300 kilometres. Neutron flows allow to spot water at great distance, explained our informant.
