Testimonials

Mayank, Tushar, and Abhirama are part of my study group on innovation and entrepreneurship at TU Berlin Space Technology - Masters of Space Engineering. They are ambitiously addressing the lack of infrastructure supporting lunar and deep space communication. They did not shy away from addressing this large issue and have developed a simple yet elegant solution concept. I got to know them as very passionate and committed. They are eager to create a sustainable business model around their vision and are making great steps in customer discovery. I’m excited to accompany them in their entrepreneurial journey towards driving the future of data communication in space.

The Celestial team (Mayank and Johannes Schumacher), I have met for the first time at the ESA Investment Forum in Darmstadt, organised by cesah at the end January 2019. This event aimed at connecting start-ups and investors. At that time, I learned about their goal to enable cis-lunar communication through a Cube-sat based lunar data relay constellation. Since then, we have been in contact through calls, in which I was providing my feedback on the concept. In addition, our paths crossed multiple times at industry relevant events and conferences. The team is committed, coachable, and ambitious! They are not backing down from thinking big and following an ambitious vision, i.e. a long-term and large-scale project of a lunar constellation..

Celestial was one of this year most promising project, by showing all the technical skills and the social abilities to grow as a profitable startup. We hope to see them enter the Swiss Space Ecosystem soon with their product.
