A Tiny, Inexpensive Satellite Will be Studying the Atmospheres of hot Jupiters

The Colorado Ultraviolet Transit Experiment (aptly nicknamed CUTE) is a brand new, NASA-funded mission that goals to check the atmospheres of large, superheated exoplanets – often called sizzling Jupiters – round distant stars. The miniaturized satellite tv for pc, constructed by the Laboratory for Atmospheric and Space Physics (LASP) on the College of Colorado Boulder, is ready to launch this Monday, September twenty seventh on an Atlas V rocket.

Small-sized satellites like CUTE, often called CubeSats, are nothing new. They’ve lengthy been a staple of collaborative college pupil tasks, as low-cost methods to get engineering expertise in house. However currently, researchers have been pushing the boundaries of what CubeSats are able to, placing them to the take a look at with increasingly bold tasks. In 2018, for instance, the primary interplanetary CubeSats (MarCO-A and-B) left low earth orbit and traveled to Mars with NASA’s InSight lander, offering communications and telemetry for the lander because it descended in the direction of the planet. CUTE, then again, will stay in Earth orbit, however the scope of its ambition is equally lofty for such a small spacecraft.

Its main mission is to know the unstable physics round sizzling Jupiters. These monumental exoplanets haven’t any analog in our photo voltaic system: they’re comparable in dimension to our fuel giants, however orbit a lot nearer to their stars, and might attain temperatures of over 7,800 levels Fahrenheit.

CUTE principal investigator Kevin France explains that “as a result of these planets are parked so near their mum or dad stars, they obtain an amazing quantity of radiation.” That radiation heats the planets, inflicting their atmospheres to inflate and broaden. A few of the fuel ultimately escapes and streams away from the planet.

CUTE will spend its 7-month mission observing as many sizzling Jupiters as it will probably (10 at minimal), and measuring how rapidly fuel is escaping from them. Atmospheric escape is a course of that occurs to all planets, Earth included, however nothing like as rapidly or on such giant scales as on these sizzling Jupiters. Nonetheless, understanding the way it works on these giants will help researchers perceive the way it works on rocky worlds too. If profitable, the info CUTE gathers will probably be used to know the processes of atmospheric escape on a variety of various planet sorts.

That is the primary time a NASA-funded CubeSat has been used to check exoplanets. LASP Director Daniel Baker is worked up by what these tiny spacecraft can accomplish. “As little as a decade in the past,” he mentioned, “many within the house neighborhood expressed the opinion that CubeSat missions had been little greater than ‘toys. There was recognition that small spacecraft could possibly be helpful as educating and coaching instruments, however there was widespread skepticism that forefront science could possibly be finished with such small platforms. I’m delighted that LASP and the College of Colorado have led the best way in demonstrating that exceptional science might be finished with small packages.”

The launch of CUTE from Vandenberg Air Pressure base in California might be watched live on September twenty seventh, with liftoff deliberate for two:12 PM EDT.
