Equipment attached to China’s 500-meter Aperture Spherical Telescope, or FAST, is being upgraded to search for extraterrestrial civilizations.

In a China Daily story, Tong-Jie Zhang of Beijing Normal University’s astronomy department explains: “At present, the back-end equipment is being upgraded, and it is expected that new observations can be made after September, when the extraterrestrial civilization search will be launched.”

Telescope time

FAST is the largest single-aperture telescope in the world; its 19 beam receiver allows rapid and sensitive sky surveys with robust Radio Frequency Interference (RFI) rejection, a key techno-ingredient for SETI activities.

The Chinese astronomical community has planned a drift-scan program covering 57% of the celestial sphere called Commensal Radio Astronomy FAST Survey (CRAFTS).

CRAFTS plans to use more than 5,000 hours of telescope time and to commensally analyze the sky survey data to find possible ETI candidate targets and to then do follow-up observations on these targets.

In the longer term, FAST is planning a sensitive phased array feed, which could provide roughly 100 simultaneous beams, excellent for a next generation SETI sky survey work.
