SpaDeX docking: ISRO arrests drift between satellites
The Hindu
The ISRO, which had postponed the planned docking of the two SpaDeX satellites, has arrested the drift between the spacecraft.
The Indian Space Research Organisation (ISRO), which had postponed the planned docking of the two SpaDeX satellites, has arrested the drift between the spacecraft.
“SpaDeX Docking Update: The drift has been arrested and spacecraft put in a slow drift course to move closer to each other. By tomorrow, it is expected to reach initialisation conditions,” ISRO posted on Thursday (January 9, 2025).
On Wednesday (January 8, 2025) hours before it was scheduled to carry out the SpaDeX docking experiment, ISRO said that the docking experiment which was scheduled to take place on January 9 has been postponed as the drift between the satellites was found more than expected.
“While making a maneuver to reach 225 m between satellites the drift was found to be more than expected, post non-visibility period. The planned docking for tomorrow is postponed. Satellites are safe,” ISRO had announced.
A few hours before this it had initiated the drift on the Spacecraft A to move closer from 500m to 225m.
This was the second time ISRO postponed the SpaDex docking experiment.
The docking of the two satellites was initially scheduled for January 7 but was postponed to January 9. Though ISRO said that the drift has been arrested, it has not announced the new date and time for the docking experiment.

VinFast’s entry into India is a strategic one, and it comes with real investment. The company is setting up a manufacturing facility in Tuticorin, Tamil Nadu, with an initial capacity of 50,000 vehicles per year, scalable to 150,000 units annually. With an investment of up to USD 500 million, this is not a soft launch—it is a full-fledged push into what is one of the world’s most promising auto markets.

On June 7, 1742, Prussian mathematician Christian Goldbach wrote a letter to Swiss polymath Leonhard Euler. Why does it warrant attention, you seem to be asking. Goldbach outlined a conjecture that bears his name in this letter, a conjecture that is now one of the oldest and most famous unsolved problems in all of number theory. Intrigued? A.S.Ganesh hands you more details about Goldbach and Goldbach’s conjecture…
