Article: Inside China Tech: FAST keeps big eye on space after Arecibo collapse

Impact Score

6 / 10

AI Summary (Processed Content)

The collapse of Puerto Rico's Arecibo Observatory has left China's Five-hundred-metre Aperture Spherical Telescope (FAST) as the world's only operational giant, single-dish radio telescope.

Dubbed "Sky Eye," FAST is the world's largest such instrument, with a dish area as large as 30 football fields and 2.5 times the sensitivity of Arecibo. It became fully operational in January 2020 after opening to domestic astronomers last year.

The telescope is now expected to be opened to foreign scientists starting next year.

Main topics: The Arecibo Observatory's collapse, China's FAST telescope as its successor, and FAST's specifications and operational status.

Inside China Tech: FAST keeps big eye on space after Arecibo collapse
- FAST – short for Five-hundred-metre Aperture Spherical Telescope – has a dish as large as 30 football fields
- Dubbed ‘Sky Eye’ by Chinese authorities, FAST is expected to be open to foreign scientists from next year

Hello, this is Bien Perez from the South China Morning Post’s Technology desk, with a wrap of our leading stories this week.
Puerto Rico’s massive space telescope, the Arecibo Observatory, has ended 57 years of astronomical discoveries after sustaining severe damage since August of this year. The 900-tonne instrument platform of the telescope, which was featured in the 1995 James Bond film GoldenEye starring Pierce Brosnan, collapsed on Tuesday.
That has left China’s Five-hundred-metre Aperture Spherical Radio Telescope (FAST) as the world’s only giant, single-dish space telescope in operation.

Dubbed by Chinese authorities as “Sky Eye”, FAST was initially opened for domestic astronomers in April last year and became fully operational in January this year.
The world’s largest full dish telescope, which has been featured in an episode of US science documentary television series Cosmos: Possible Worlds, comprises an area that is as large as 30 football fields and is 2.5 times more sensitive than Arecibo, according to the Chinese Academy of Sciences (CAS).

FAST, however, is expected to be open to foreign scientists from next year, according to a report last month by state-backed media People’s Daily.
