China launched into orbit candle an area of ​​25 square meters, placed in the payload capsule of a recently launched rocket, in order to de-orbit it and avoid debris.

This was the first time in the world that the system candle disproportionate in the sense that Global Times from the developers of the system on Tuesday.

new formula

Device candle The deorbit mechanism, developed by the 508 Institute of the Shanghai Academy of Space Technology (SAST), is designed to allow failed spacecraft to leave orbit earlier to help control the spread of space debris and debris.

candle was installed in the launch vehicle payload capsule Long March-2D Y64 which was launched into space on June 23, and the system was successfully launched into orbit on June 26, according to SAST.

system candle It measures 25 square meters and could allow a 300-kilogram payload capsule to re-enter Earth’s atmosphere within two years, freeing up valuable orbital resources, according to SAST developers.

the size candle Wild also set a record, the developers said.

candle It is made from ultra-thin materials and is less than one-tenth the diameter of a hair in thickness. Such lightweight, high-strength textiles mean the sail system could be installed aboard any mature spacecraft, according to SAST.

This is how a candle works

SAST explained Global Times that the system candles Deorbiting is like a giant kite in space that can help slow down a spacecraft’s launch.

candle SAST uses the aerodynamic drag generated by the thin atmosphere of the low-orbit environment to slowly decelerate the satellite and gradually leave its original orbit, according to a SAST message explaining how the system works.

Taking as an example a small satellite with an orbital altitude of 750 kilometers and a mass of 15 kilograms, it can continue to operate in orbit for 120 years and even longer after the end of its life if measures are not taken to deorbit. Usage candle A 2.25 square meter deorbit space could reduce the deorbit time for satellites to less than 10 years.

China tested the system candle a similar 2.25 square meter passive deorbital vehicle codenamed Taurus for the first time in September 2019. (Europa Press)
