ISRO to launch SpaDeX mission on December 30

India's SpaDeX mission, intended to develop and demonstrate technology required to dock and undock spacecraft in space, will be launched using PSLV-C60 on December 30 from Satish Dhawan Space Centre, Sriharikota, ISRO said. On December 21, the launch vehicle was integrated and moved to the First Launch Pad, for further integration of satellites and launch preparations.

ISRO has also put up the fast time-lapse video of the moving of PSLV-C60, which was fully integrated up to PS4 at the PIF facility for the first time, to the First Launch Pad, in its X account.

On December 30, people can witness the launch live at the Launch View Gallery after registering for it. The registration started on Monday at 6 pm, ISRO said in its website.


SpaDeX mission is a cost-effective technology demonstrator mission for the demonstration of 'in-space docking' using two small spacecraft launched by PSLV, ISRO said in an explainer on the subject.

This technology is essential for India's space ambitions such as Indian on Moon, sample return from the Moon, the building and operation of Bharatiya Antariksh Station (BAS), ISRO stated in an explainer.

In-space docking technology is essential when multiple rocket launches are required to achieve common mission objectives. Through this mission, India is marching towards becoming the fourth country in the world to have space docking technology, it added.

According to the ISRO, SpaDeX mission consists of two small spacecraft (about 220 kg each) to be launched by PSLV-C60, independently and simultaneously, into a 470 km circular orbit at 55 ° inclination, with a local time cycle of about 66 days.

SpaDeX mission was floated to develop and demonstrate the technology needed for rendezvous, docking, and undocking of two small spacecraft (SDX01, which is the Chaser, and SDX02, the Target, nominally) in a low-Earth circular orbit, the explainer added.
