In the coming years, a number of next-generation observatories and arrays will become operational. These facilities will make major contributions to multiple fields of astronomy: exploring the mysteries of the early Universe, studying gravitational waves, determining the role of dark matter and dark energy in cosmic evolution, and directly image “Earth-like” exoplanets.
Unfortunately, this revolutionary development in astronomy may be going up against another major project: the creation of mega-constellations. Because of this, the SKA Organization (SKAO) – which oversees the international Square Kilometre Array (SKA) – is insisting that corrective measures be taken so satellites won’t interfere with its radio observations once it’s operational.
When complete, the Square Kilometer Array (SKA) will be the largest radio telescope array in the entire world. The result of decades of work involving 40 institutions in 11 countries, the SKA will allow astronomers to monitor the sky in unprecedented detail and survey it much faster than with any system currently in existence.
Such a large array will naturally be responsible for gathering an unprecedented amount of data on a regular basis. To sort through all this data, the “brain” for this massive array will consist of two supercomputers. Recently, the SKA’s Science Data Processor (SDP) consortium concluded their engineering design work on one of these supercomputers.
