Docking process of Shubhanshu Shukhla's Dragon spacecraft
SpaceX's Dragon spacecraft pulled off a smooth docking with the International Space Station (ISS) at 4pm IST on Thursday.
This move is key for swapping astronauts and keeping the station running.
The whole thing is a careful, step-by-step process to make sure everyone stays safe.
First, Dragon matches the ISS's orbit
First up, Dragon uses its thrusters for hours to match orbits with the ISS.
A short engine burn then brings it from several kilometers behind and below to align its trajectory toward the docking port—all about lining things up perfectly.
Checkpoints on the way to the ISS
Dragon then passes through checkpoints, finally reaching just 20m from the ISS.
At this point, everything runs on autopilot: lasers and thermal cameras help guide its position, while safety systems stand by in case anything goes off-script.
Final step: connect with docking port
For the last step, Dragon's capture ring gently connects with the ISS docking port. Then 12 hooks lock it tight for an airtight seal.
After some quick pressure checks, hatches open—and crew can move between spacecraft safely.
