2. IN THE SPAN OF A DAY OR WEEK OR MONTH…
An illegal logging road
appears in the rainforest...
and 1,000-year-old trees
are lost forever.
IN THE SPAN OF A DAY OR WEEK OR MONTH…

3. A plane departs
from a location of interest —
and a military
loses situational awareness.

4. IN THE SPAN OF A DAY OR WEEK OR MONTH…
A community
is devastated by a natural disaster...
and the local government
lacks the ability
to deploy emergency
responders effectively.

5. MISSION
To image the whole world every day,
making change visible, accessible and
actionable.
