Researchers laser-sintered lunar soil simulants into Lego-like building blocks that can be rearranged without extra joining material. The proof-of-concept blocks reached a peak compressive strength of about 3.4 MPa.
Researchers developed and tested a model for using compressed gas to carry rock chips out of a deep borehole on Mars. The model showed reasonable agreement with vacuum and full-system experiments, offering guidance for drilling into buried ice deposits.
The MAJIS instrument aboard the European Space Agency’s JUICE spacecraft performed well during its August 2024 Earth-Moon gravitational assist. Tests supported its updated wavelength calibration and showed that its brightness measurements were close to expected values, strengthening confidence in future observations around Jupiter.
Chemical and isotopic evidence from a silicate inclusion in the Aletai iron meteorite links IIIE iron meteorites with HED meteorites. The findings provide physical evidence that the metal core and rocky mantle of an early asteroid shared a common origin.
