Petrochemistry and Chemical Features of Lunar Glassy Spherules [PDF]
Symposium - International Astronomical Union, 1972 The major elements of glassy spherules from samples 12001.73, 12057.60 and 12070.37 of lunar fines have been determined by electron probe analysis. The bulk chemistry of these spherules (which are between 200 μm and 62 μm in size) falls in most cases within the range of gabbro-peridotite and gabbro-anorthosite.In individual spherules, the grade of ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, EarlyView.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, EarlyView.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...
