Announcement: Vera C. Rubin Observatory

12 Marzo 2024: Vera C. Rubin Observatory’s 8.4-meter combined primary-tertiary mirror is officially home after being moved to the main observatory’s maintenance floor, where it will remain for the rest of the construction phase and throughout Rubin’s ten-year Legacy Survey of Space and Time. The mirror, which is still an uncoated glass blank, arrived on Cerro Pachón, the mountain in Chile where the observatory is located, in May 2019. Since then it’s been safely packed in a transport box and stored in a building outside the observatory. On 7 March the summit team loaded that box onto a specialized truck to make the short, but important, 600-meter (650-yard) journey from the storage building to the observatory. That wasn’t the only major move on the summit that week. To make room for the glass mirror in the observatory, the transport team first had to remove the 8.4-meter steel stand-in mirror. The successful transport of …

2 Octubre 2023: Scientists, including astronomers from the International Astronomical Union Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (IAU CPS), have published a paper in Nature assessing the detailed impact of the BlueWalker 3 satellite on astronomy. Building on initial observations from shortly after its launch, these new results complement the initial understanding of this unusual satellite and the paper contains details of how the satellite’s brightness changes over time and the visibility of jettisoned hardware. With companies intending to deploy more commercial satellites in the coming years, this paper highlights the need for pre-launch impact assessments. “The interference of satellites in astronomy has become an increasingly pressing issue over the last few years,” commented first author Sangeetha Nandakumar from the Instituto de Astronomía y Ciencias Planetarias, Universidad de Atacama Chile. BlueWalker 3 was launched into low Earth orbit on 10 September 2022 by AST SpaceMobile …
