What motivated you to volunteer as a NASA citizen scientist? How did you learn about NASA citizen science?

I've been interested in science and space forever, since I was a child. Later as a young man, I met two cosmonauts – Sigmund Jähn and Waleri Bykowski – personally, and it was fascinating when they spoke about their flight and what they saw. There were too many setbacks in my own health to apply for a space program, but I always wanted to take a part, however small, in the exploration of space. So it was an easy decision to join Zooniverse when I read about the program in a newspaper.

"I am a coauthor on the final two Exoplanet Explorers papers, as I’ve contributed more than 10,000 light-curve classifications to the project, including a dozen good exoplanet candidates."

What do you do when you’re not doing science with NASA? Tell us about your job and your hobbies.

I am a business consultant for human resources payroll systems (Germany has the most complex payroll regulations in the world), and I like the work because there is a lot of interaction with other people and the businesses they're in. My hobbies include glider planing with two historic planes at Stoelln/Rhinow airfield, the oldest airfield in the world (Otto Lilienthal was flying here in the 1890s); sailing with traditional sailing ships on the Baltic Sea.

What have you learned about the process of science from your time on NASA citizen science projects?

I learned about the complexity of modern research, using scientific sources of knowledge (e.g., star catalogues), and interacting with other people to check scientific results. I am very pleased to have such a lot of interaction with the astronomers at the Backyard Worlds: Planet 9 project, and to see how they work, run projects, and apply for resources as well.

Which peer-reviewed research publications have you contributed to through your citizen science work? What was your role in the research and writing process?

I am a coauthor on the final two Exoplanet Explorers papers, as I’ve contributed more than 10,000 light-curve classifications to the project, including a dozen good exoplanet candidates. Due to limited resources for further research, only a small fraction of the projects’ identified exoplanet candidates could be examined and confirmed by the astronomers.

The papers I was part of were led by Veselin Kostov and Jon Zink, respectively:

We’re aware that not everyone has equal access to speedy computers and internet signals. Was this a problem for you? And if it was how did you overcome it?

The internet's not perfect in Germany, but it's OK. You can even work while travelling on trains or at the airports. Looking for elephants in wildlife photos, for instance, is much more interesting to me than looking around in a crowded airport terminal.

What are your favorite NASA citizen science projects to work on, and why?

Backyard Worlds: Planet 9, because the professionals take great efforts to let the citizen scientists really be part of the whole project. That's awesome. For instance, I was part of a very successful side project created by citizen scientists called the Plane Party last autumn and winter that delivered a bulk of new brown dwarf candidates. And to learn that ground and space telescopes like Keck Observatory and Hubble were directed to check the findings of fellow citizen scientists makes me really proud.

What have you discovered or learned as a NASA citizen scientist?

I never thought I could work with professional star catalogues like AllWISE or Gaia DR2 one day, but I did. And you also learn about the hard decisions science projects have to make and the competition for resources that they face.

What advice would you give to others who might want to volunteer with NASA citizen science?

Just try it, find out what you like, have fun, and ask the professionals to really share with you. There are a lot of interesting projects out there. And if you really like it, you can always dig deeper.

Who have you met during your NASA citizen science work who inspires you?

Marc Kuchner is a great scientist, a great project leader, and a fine fellow too.

How much time do you spend on NASA citizen science projects?

Some hours a week.
