The extension had Ladee flying during Tuesday morning's lunar eclipse; its instruments were not designed to endure such prolonged darkness and cold.
BMD was measured by using Lunar or Hologic instruments.
By comparing with the topography data from the Lunar Laser Ranging Instrument (LLRI) on Chandrayaan-1, they concluded that the surface processes play an important role in the small-scale variations of the H _2) number density in tenuous lunar atmosphere.
In the spectra taken near lunar poles, the instrument showed prominent absorption bands at 2.8-3 micorrespondingonding to OH/H2O but these bands were negligibly small in the low latitude spectra [26].
The same instrument (Lunar Prodigy Advance, #PA+41562, GE Healthcare) was used for every patient.
At the time of study, all patients with UCTD underwent bone densitometry using a Lunar-DPX-L DEXA instrument (Lunar Radiation Corporation, Madison, WI, USA).
Bone mineral density from the whole body, lumbar spine, femur and forearm were measured with the Lunar DPX-MD instrument.
BMD (g/cm) was measured by dual X-ray absorptiometry with a Lunar DPX-MD instrument (GE Medical Systems, Madison, WI, USA) using specialized software for whole body, lumbar spine, femur (neck, trochanter, Ward's triangle and shaft) and forearm (including radius and ulna), as described previously [ 22].
Moon Electrostatic Dust Analayser (MESDA), consisting of two instruments namely Lunar Surface Potential detector and Lunar Dust Detector and Chandra's Surface Thermal Experiment (CHASTE) which may determine the thermal profile up to 10 cm depth in the regolith are being considered for the Lander.
This was followed in 1998 by the Lunar Prospector mission, whose instruments indicated the presence of excess hydrogen at the lunar poles, which is likely to have been caused by the presence of water ice in the upper few meters of the regolith within permanently shadowed craters.
