Use the internet (e. g. wikipedia, NASA, ESA, etc.) to look-up a past Earth science mission (Earth Observation, Satellite meteorology, Earth magnetic fields, etc.). Please choose a mission that was successful. Write a paragraph (10 sentences or so) that

(a) Describes the mission profile (launch, orbit, etc.). Be sure to explain the rational behind the
choice of orbit.

(b) What were the scientific measurements/discoveries made by the mission?

(c) What is the impact of the data gathered by this mission? Does it directly effect our daily
lives? Does it have something to do with future climate?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
