The Space Tester || Discover Outer-World Experiences in Everyday Life


You may already know me from my international travel blog The Travel Tester, but if that isn’t the case, let me introduce myself to you first.

Nice to meet you! I’m Nienke Krook (neen-kuh kro-wk – but don’t worry if you still can’t pronounce it) and sometimes you’ll also see my boyfriend Nick Vullings join me in my adventures here on the blog. We’re both from The Netherlands, but we met by chance in a hostel in Sydney in 2008.

Since then, we lived in Sydney, Australia between 2011 and 2013, London, England between 2013 and 2019 and are currently based in my hometown of Amsterdam in The Netherlands. In the meantime, we’ve travelled to over 40 countries on 5 continents… and the list keeps on growing.

Nick is an architect and I work as a blogger and social media manager. For our jobs we both get to travel the world for a living, sometimes on individual work trips, but luckily also quite a lot together.

Because we always look for ways to keep learning and develop ourselves professionally, we don’t take the easy route and have moved around quite a bit.

It hasn’t always been smooth sailing trying to live in another country and settling in, but we learned that we make a perfect team and are capable of building a new life from scratch no matter where we are.

You can definitely say that we trained a few of our astronaut skills, such as adaptability and cultural understanding while living abroad. If we can do it, we’re sure that you can too and we would love to help you plan your next adventure. Get in touch!

Like many other professional travel bloggers, We rely on advertising here on The Space Tester. This can be banner advertising or the creation of unique content in collaboration with brands and destinations.

How it works is that partners contact us (or we contact them if we have a cool idea of how we can work together) with a concept that fits the mission of our website.

We make sure to always disclose partnerships at the bottom of our articles, so there is full transparency to you. We only work together with a brand if we can share our personal experience, so that means we’re getting send products or are invited to visit a certain locations to see and try things for ourselves.

For example, one day we might be testing a telescope, another day we test a space-themed book, website or app and then we’re off to test a science/space museum visit, or space-themed restaurant or hotel.

Because our partners are so different, it can be hard to choose who is the best fit, but in the last few years, we’ve learned what works and what doesn’t and currently we’re saying NO to about 90% of all offers that we get. This way, we only work with brands and destinations that we’re really excited about and that we would love to recommend you.

For those collaborations that do go ahead, we either get compensated with the product or experience itself, with a fee for creating a certain amount of content, or we get into an affiliate-partnership, where we get a small cut if you book or buy anything through a specific link in the article. Everything of course with no extra costs to you.

All of our brand partnerships keep the content that your read on our website 100% free and we’re sure you’d like us to keep it that way!

Are you a brand interested in working with us? Please see all options here [soon] >
