Iran claims it has completed a second suborbital test of new rocket

According to Iran’s state-run press, it yesterday successfully completed the second suborbital test of its new Zuljanah rocket.

The announcement said nothing about where or when the launch took place. According to this Iranian report, the rocket “has two solid propulsion phases and a single liquid propulsion phase.”

The rocket had completed a suborbital test in January 2021. In March 2022 satellite imagery suggested a second test had exploded on the launchpad sometime in late February.

Since the video of the launch provides no specific information about where or when, it is quite possible it is simply footage from the January 2021 launch. It will require orbital imagery to confirm this claim.

Satellite photos suggest Iran had a launch failure with rocket explosion on launchpad

Based on new satellite photos, it appears that an attempt by Iran to launch a satellite failed this week when the rocket exploded on the launchpad.

Before and after images taken by imagery satellites from two different private companies, Maxar and Planet Labs, suggest the incident likely occurred around February 26th.

Satellite images from Maxar Technologies seen by The Associated Press show scorch marks at a launchpad at Imam Khomeini Spaceport in Iran’s rural Semnan province on Sunday. A rocket stand on the pad appears scorched and damaged, with vehicles surrounding it. An object, possibly part of the gantry, sits near it.

Successful launches typically don’t damage rocket gantries because they are lowered prior to takeoff. Iran also usually immediately trumpets launches that reach space on its state-run television channels, and it has a history of not acknowledging failed attempts.

The news reports claims that the failed rocket was Iran’s Zuljanah rocket, which uses solid rocket motors for its lower stages. Zuljanah has never made orbit, having been unveiled one year ago after a single suborbital test flight.
