AI crater navigation maintains accuracy for lunar mapping
—
What the study found The study found that STELLA, described as the first end-to-end crater-based navigation (CBN) pipeline for long-duration lunar mapping, can maintain metre-level position accuracy and sub-degree attitude accuracy on average in a lunar mapping setting. Why the authors say this matters The authors say this bridges a gap between CBN studies for…
Rarefaction weakens electromagnetic flow control in hypersonic plasma
—
in EngineeringWhat the study found Rarefaction effects weaken the influence of electromagnetic control in hypersonic flow around a hemisphere. The study also indicates that the unified gas-kinetic wave-particle (UGKWP) method can model this kind of electromagnetic flow across near-continuum to rarefied conditions. Why the authors say this matters The authors conclude that the results highlight UGKWP's…
