ISS Spacewalks

About Makeover Monday

MakeoverMonday is a social data project: “Each week we post a link to a chart, and its data, and then you rework the chart. Maybe you retell the story more effectively, or find a new story in the data. We’re curious to see the different approaches you all take. Whether it’s a simple bar chart or an elaborate infographic, we encourage everyone of all skills to partake. Together we can have broader conversations about and with data.”

Starting from Jan 08, 2018, I decided to put aside one hour on Monday weekly to create some visualization and find some insights from the data.

The datasets are published each week at: MakeoverMonday Datasets.

Makeover Monday 20190429

This week’s data is about spacewalking at the International Space Station (ISS) from NASA. The original artical and viz can be found here. The original viz compares the spacewalks in US/Russia spacesuits from 1998 up to now, as these two countries have played most important roles in the development of space research and technology. I like the background image of the viz :)

My Visualization

This week, I ended up with simple bar chart (and cute icons!). I noticed the overall spacewalk trend in the original viz – peaked around 2007 and decreasing since then. I am curious does this trend holds true with # of spacewalkers as well.

Insights

• We can see two peaks of the unique spacewalkers in a year – one around 2001, and another around 2008. This is very similar to what we see of the spacewalk counts trend.
• Since 2008, in 10 years, we see much fewer spacewalkers – potentially because of the effect of the financial crsis (the space costs might be cut since then).
