Spectroscopy and Space Exploration: Planetary Bodies and other Celestial Objects
Spectroscopy magazine is pleased to welcome you to the “Planetary Bodies and Other Celestial Objects” landing page, one of three landing pages in our “Spectroscopy and Space Exploration” content series.
This landing page houses several articles that focus on the great work of spectroscopists that used spectroscopic techniques to facilitate technological and scientific advancements for exploring planetary and celestial bodies and meteorites. Spectroscopic topics that are covered in these articles include an in-depth look at the versatility of laser-induced breakdown spectroscopy (LIBS).
How NASA Scientists are Using Raman Spectroscopy to Study Exoplanets
By: Will Wetzel
The study of exoplanets, or planets outside of our solar system, is becoming increasingly important in space exploration. Scientists are working to characterize these planets and Raman spectroscopy is playing a key role. Andrew Mattioda, a research scientist at the National Aeronautics and Space Administration (NASA) Ames Research Center, is on the front lines of this research.

Unlocking the Secrets of Exoplanet WASP-39b: Early Release Science with JWST NIRISS Reveals Intriguing Atmospheric Composition
By: Jerome Workman, Jr.
In a pioneering study published in Nature, researchers have presented their findings on the atmospheric properties of the exoplanet WASP-39b. Using data obtained from the JWST NIRISS instrument, the team successfully breaks model degeneracies and reveals intriguing insights into the exoplanet's heavy-element enhancement, carbon-to-oxygen ratio, potassium-to-oxygen ratio, and the presence of wavelength-dependent, non-grey clouds.

Advancing Hydrogen Detection on Airless Planetary Bodies through Laser-Induced Breakdown Spectroscopy
By: Spectroscopy Staff
New research demonstrates significant progress in accurately measuring hydrogen on airless planetary bodies using laser-induced breakdown spectroscopy (LIBS). These findings provide valuable insights into the spatial distributions and depth profiles of hydrogen-bearing materials, addressing previous uncertainties in remote-sensing observations and opening doors for future space exploration missions.

Handheld Laser-Induced Breakdown Spectroscopy (hLIBS): A Valuable Tool for Terrestrial and Extraterrestrial Recognition of Meteorites in the Field
By: Giorgio S. Senesi
The role and performance of handheld laser-induced breakdown spectroscopy (hLIBS) devices is discussed in the context of meteorite research exploration while targeting specific questions of geologic interest in the field. The fast data acquisition and minimal sample preparation features of these devices make them very attractive as candidate tools for future astronauts in geochemical mapping, resource prospecting, sample selection, and hazard identification. Although hLIBS instruments have recently become commercially available, they have not yet been widely applied to meteoritical field campaign. This article reviews how the very promising advanced analytical tool hLIBS may be helpful to classify and discriminate meteorites in the field.
