Problem I  Aura Produces a Lot of Data Every Day!  The Aura satellite is designed to study the composition of Earth's atmosphere, and produces 31,755 DVDsworth of data every year. How much data does it produce in one day? [Answer: 31755 DVDs/365days = 87 DVDs each day!] Problem II  The Orbit of Aura Around Earth.  The Aura satellite orbits Earth 360 orbits in 25 days. How many orbits does it complete in one day? [Answer: 360 orbits/25 days = 14.4 orbits each day therefore it completes 14 orbits in one day!] Problem III  An Ozone Hole in the Arctic Region.  Ozone is a molecule that forms high up in Earth's atmosphere and blocks harmful ultraviolet light from reaching the ground. In 2011, the Aura spacecraft detected 17,052,000 tons of ozone destroyed over the Arctic Region during a 1week period of time. How much ozone was lost in a single hour during this one week? [Answer: There are 24 hours x 7 days = 168 hours in a week, then 17052000 tons/168 hours= 101,500 tons of ozone were destroyed each hour.] Explain your thinking: Write your own problem  Using information found in the Math Connection problems, the press release or the video program, create your own math problem. Explain why you set the problem up this way, and how you might find its answer. Evaluate your understanding: Challenge Problem  Since its launch in 2004, the Aura satellite has been returning data to scientists as it orbits Earth about 14 times each day. The data library that has been set aside for AURA can only accommodate 450,000 DVDsworth of data. In what year will the scientists have to replace the current archive with one that has a higher capacity if the Aura satellite keeps operating? Answer: Aura produces 31,755 DVDs each year, so the archive can store the data for about 450,000 DVDs/(31755 DVDs per year) = 14 years. Since it was launched in 2004, Aura will reach its capacity limit in the year 2004 + 14 = 2018.
