Collect electromagnetic waves |
|
Collecting ability proportional to the square of
the diameter of the objective |
|
Resolve electromagnetic sources |
|
Related to the atmosphere, wavelength and
curvature of the objective |
|

Radio science observations in the L-band |
|
L-band lies in the 1400-1427 MHz region of the
electromagnetic spectrum |
|
detection of what astronomers call the 21-cm
line of hydrogen |
|
this is a portion of the hydrogen spectrum, in
the radio region of the electromagnetic spectrum, which is generated by the
neutral hydrogen clouds in the interstellar medium |
|
|
|
|
|
Observations in C-band, which is 4313-4338 MHz
and 3788-3813 MHz |
|
Radio science observations in the C-band allow
for the radio emission examination of the moon, which acts as a body at a
temperature of 200 K. |
|
Students will be able to scan the moon, and
detect the estimated 6000 joules of energy from the lunar surface. |
