Third stage of India’s PSLV rocket fails during launch
India’s PSLV rocket today (May 18 in India) experienced a launch failure in attempting to place an Earth observation satellite into orbit, with the failure occurring during the engine firing of the rocket’s third stage.
The link is cued to just before the tracking screen began showing the third stage drop from its planned trajectory. The suddenness of the loss of data as well as the drop in the trajectory suggests the engine exploded during firing, but that is pure speculation. Regardless, the launch, only the second India has attempted in 2025, was a failure.
Moreover, the first launch this year was a failure also, though the GSLV rocket in that launch performed as expected and deployed the satellite in its planned transfer orbit. At that point however the Indian-built satellite’s thrusters failed to operate, stranding the satellite in the wrong orbit, which soon decayed.
Thus 2025, which ISRO had predicted to be India’s most active year ever, is so far not turning out so well. ISRO hopes to begin launching its first unmanned test flights of its Gaganyaan capsule later this year, using its Heavy Lift Vehicle Mark 3 rocket (HLV-M3), an upgraded version of its GSLV rocket. One wonders if these issues will impact that schedule.
These failures by the space agency could however help the Modi government shift the balance of power away from ISRO and to its emerging private rocket sector. If the agency can’t get it done, maybe the private sector should be given the chance to do it. For example, the government has been pushing to have the ownership and management of the PSLV rocket transferred from ISRO to a private rocket company since in 2016. In the nine year since, there however has been little sign of this shift happening.
Part of the problem has been that none of India’s private rocket startups are really ready to take over these operations. The transfer is further made less likely by the strong resistance to change within ISRO’s bureaucracy. These failures provide political ammunition to push back against that resistance.
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.
