(I) As evidence has mounted about the threats that the
Earth is facing, from rising temperatures and ocean
acidification to deforestation and extreme weather,
NASA has given priority to missions aimed at coping
with the impacts. (II) NASA will be devising new
technology to monitor earthquake-prone regions on the
Earth via the satellites. (III) One of its newest satellites, a
$916 million observatory called SMAP (for Soil Moisture
Active Passive) was launched in January 2015. (IV) It
was designed to measure soil moisture both by
bouncing a radar beam off the surface and by recording
radiation emitted by the soil itself. (V) In July 2015, the
active radar stopped transmitting, but the passive
radiometer is still doing its job, and its maps will help
scientists forecast droughts, floods, and famines
