The world’s first commercial space telescope, called Mauve, is making waves. This compact satellite, the size of a suitcase, was launched aboard a SpaceX Falcon 9 rocket last November. It’s the first of many small spacecraft aimed at giving astronomers worldwide access to valuable observation time.
Traditionally, astronomy has relied mostly on government-funded organizations. But Blue Skies Space, a London-based company formed from University College London, saw an opportunity. They believe a market-driven approach could quickly fill gaps in our understanding of the universe.
On February 9, Mauve took its first measurements, observing a star known as eta Ursa Majoris. This bright star is about 104 light-years away and emits significant ultraviolet light, which is Mauve’s specialty. The CEO of Blue Skies Space, Marcell Tessenyi, explained that they wanted a stable star for their initial observations, one that had been well-studied before.
Ultraviolet emissions, particularly valuable for studying stellar activities like flares, have not been observed with dedicated missions for years. The last one, the International Ultraviolet Explorer, ran out of fuel in 1996. The technological advancements today allow for smaller satellites to take on this important work.
Solar flares, which can disturb radio signals and affect satellites, are a significant concern. While Earth has a protective magnetic field, Mars does not, leading to ongoing erosion of its atmosphere. By monitoring nearby stars, Mauve aims to help identify exoplanets that may be capable of supporting life.
“We’re running tests on various stars to understand the instrument better,” Tessenyi added. The scientific data is expected to start rolling in soon, giving researchers fresh insights into stellar behavior.
Already, research groups from the U.S., Japan, and several European nations have signed on with Mauve. The revenue generated will help fund Blue Skies Space’s next mission, Twinkle, which plans to directly observe exoplanets and analyze their atmospheric compositions.
Looking ahead, Tessenyi mentioned their collaboration with the Italian Space Agency to create a satellite constellation that would measure radio waves from cosmic sources. He highlighted the remarkable growth in the space sector over the past decade, particularly with affordable launch options and the rise of smaller satellites in low Earth orbit.
However, he acknowledges that commercial astronomy might always play second fiddle to large-scale government missions. While these major projects, such as the James Webb Space Telescope, push technological boundaries, Blue Skies Space focuses on utilizing existing tools in inventive ways to gather new data.
Impressively, Mauve was built in just three years—a significant contrast to the years often required for government projects. Constructed with collaboration from companies in Hungary, the Netherlands, Italy, and Latvia, this little satellite is poised to orbit Earth for at least three years, potentially changing our understanding of the cosmos.
