After successfully bringing two satellites into space, scientists of the Indian Space Research Organization (ISRO) are planning for a second spadex mission – this time to do the dock to two satellites in an elliptical orbit.
The ability to join two satellites in space, known as docking, is important for India Upcoming Chandrayaan -4 mission And the proposed Indian Anticash Station, the Planned Space Station of the country.
In the first Spadex Mission, two 220-cylogram satellites were launched in a 470-km circular orbit. With a small relative velocity between them, the satellites were allowed separately before bringing closer closer. On 16 January, he successfully docked. The experiment demonstrated their ability to receive power sharing between satellites and the command as a single overall unit.
With this, after India, Russia and China, the in-space became only the fourth country to showcase the docking capabilities. However, the feat was done in a relatively easy rounded orbit.
“Docking in a circular orbit is much easier than docking in an elliptical orbit. The reason is that the trajectory and velocity of satellites remains stable in a circular orbit, while they change in an elliptical orbit. It is essentially what means that the calculation for a point will not be relevant after a few minutes.” “This, however, will try what the Spadex 2 will use.”
This ability is likely to play an important role in future missions, such as Chandrayan -4, where many modules can be launched separately, and will require docking and ignores in both Earth and Moon’s orchers.
For the Moon Missions, ISRO usually launched a spacecraft in an elliptical earth orbit, gradually extended the appi (farthest point) through the engine burn to the perige (nearest point) to use minimal fuel. This process installs a slingshot trajectory towards the moon, which requires a practical requirement for complex missions to docking in elliptical classes.

The first docking operation took a long time, as the agency contacted it with great care.
“This was the first time ISRO was trying to do docing and ignores, so everything was to be carefully planned and tested. In fact, knowledge is being used. This mission was developed itself and was to be calibrated for reading in space. Once it was used to operate many simulations with real docking, it was very slow.
During the initial attempt, SpadX satellites were brought closer to closer, stopping at the nominated posts – 5 km, 1.5 km, 500 m, 225 m, 15 m, and 3 m – before docking. In the second attempt, the post-temperature, the process was smooth and fast, with the path for redocking with low stops.
