The files below are taken from the payload data logger. It logs the location, height, internal and external temperature of the payload box once a second throughout the flight.

The Randwick datafile is an Excel file each row represents the data recorded in a second.

The Randwick GoogleEarth file is a file that can be loaded in Google Earth and allows you to see the fligthpath of the balloon as a 3D representation. For details on how to import this data into Google Earth click here.

Plot on Google Earth of the flight path

Plot on Google Earth of flight path over land

The best way to see the flight path is as a 3D model using Google Earth. You will need to install Google Earth on your computer first. Then download the file containing the data from the flight recorder. Open it in Google Earth. A dialogue box will pop up as you open asking if you want to adjust altitudes to ground height. Untick this to see the path as a 3D plot.

Do you notice any unusual features of the flight path? Can you suggest any explanations?

In the payload there was a satellite data logger. It worked out the balloon's height and location using a signal from a satellite and recorded it onto a memory card. I've created an Excel version of the file that shows just height above sea level in metres against time since launch in seconds.

I wonder if you can tell the story of the balloon's journey from the information in this file? Can you find the time after launch that the balloon burst? Can you find out the maximum altitude achieved? Can you find the time after launch that the payload landed? Can you work out how long the flight was? Can you work out the speed of ascent and descent? Is there any other information about the flight you can discover from the data?

You might find it helps to plot the data as a chart. This is easy to do by selecting the data and then using the chart tools in Excel.

Let me know anything you discover by leaving a comment.

Do leave comments and observations. Do you notice anything unusual about different stages of the ascent? Did the video match what you expected to see from the payload camera? Can you pick out any landmarks in the video? What do you think will happen when the balloon bursts? If we were to launch again would you recommend particular weather conditions so that we get good pictures?

Imagine you were the Lego figure. How would you feel throughout the ascent? Which parts were most exciting/frightening/beautiful? Which parts would be hottest/coldest? How hot or cold would they be? What landmarks could you see?
