ISRO considering doing more docking tests with Spadex satellites
India’s space agency ISRO has delayed the undocking of its two Spadex satellites as it considers a plan to do more docking tests.
The original plan was to have the chase satellite complete only one docking with the target vehicle, after which the two satellites would separate and spend the next two years doing different work. That plan is being reconsidered.
[Isro chairman V.] Narayanan said in Sriharikota that they have to think of the money involved in such projects and utilise it to the maximum. “Now we are in the process of reviewing when to do the undocking, the power connections and when to totally separate them again and dock again. All these processes are going on. We do not want to undock and leave it,” the Isro chairman said.
“We have loaded five kg of propellant on both the satellites. The propellant is needed for docking and undocking exercises. Currently we have 60 to 70 per cent of the propellant (as of January 29) remaining in the spacecraft. There are going to be a lot of experiments in the docking, undocking, power connection exercises and it is not a one time exercise,” he said.
Sources at ISRO also suggest there may be issues with the docking that still need analysis.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

4. Donate by check, payable to Robert Zimmerman and mailed to
