India’s Space Docking and Chinese Reactions

The Chinese reactions to India’s Space Docking Experiment has been vitriolic. While their media has grudgingly acknowledged the achievement, the reaction from the public and those who have watched the video has bordered on hostility. Many have said that the space docking has been a fake. One has gone on to acknowledge its success and has felt the need to contain India militarily. In his opinion, India will put this knowledge to military use against China and hence it must be contained. Resultantly, one has had to respond to these reactions with reaction and proof of docking from the space community in Switzerland. Watch Both the short videos to get a holistic idea.

#SpaDeX update

"Spacecraft docking successfully completed! A historic moment.

Let’s walk through the SpaDeX docking process:

Manoeuvre from 15m to 3m hold point completed. Docking initiated with precision, leading to successful spacecraft capture. Retraction completed smoothly, followed by rigidisation for stability. Docking successfully completed."

https://x.com/isro/status/1879749119759311078?t=Q5lp0-S6xaHeKL1GqepaRQ&s=19

India is the 4th country with space docking capability after US, Russia, and China.

#ISRO has limited time of next few days for fourth attempt and after that the combination of right illumination conditions and ground station pass-over will change and they'll might have to wait till March for attempting further.
