  Los Angeles CA (SPX) Mar 24, 2025 NASA's SPHEREx mission, newly launched into low Earth orbit on March 11, has taken a major step toward beginning its cosmic survey by discarding its dust cover. On March 18, mission controllers successfully directed the observatory to jettison the shield that safeguarded the telescope's aperture from particles and moisture. This crucial component, which measured roughly 25 inches by 16 inches (64 cm by 40 cm), was designed to protect sensitive elements, including the trio of mirrors central to SPH ... read more |
