FAILED: Safir-2 - Zafar-1 - Iman Khomeini SLC - 09 FEB, 2020 19:18:16 ICT (UTC+3:30)
#21
This is the third time the SLV has failed to perform. I understand its not easy.......but yes, it is very frustrating.

At this point, IRGC needs to take over the program and militarize/classify it until a civilian government made of humans are elected.
Only announce launches after they occurred with little NOTAM notice and most importantly, completely take over the chain of production and vet out potential roaches from the current space program.

Iran's Zafar satellite launch fails again

2020-02-09

According to Iran ’s official IRIB news agency, Mohammad Javad Azari-Jahromi, Iran ’s Minister of Information and Communications Technology, said: 'The Zafar (Victory in Persian) satellite will be launched from Semnan into orbit at a speed of 7.400 kilometers per second. '

The 113-kilogram Zafar satellite will be launched by the 'Simorgh' rocket into 530 kilometers Low Earth orbit. 'The main task will be to collect images. Iran needs these data to study earthquakes, respond to natural disasters and develop agriculture.'

A spokesman for the Ministry of Defense said that the satellite was launched at 19:15 and that about 90% of its orbital path was also completed. The satellite reached an altitude of 540 kilometers and a speed of 6'500 meters per second, but the satellite did not reach orbital insertion speed.

He added: "The satellite was also in orbit for a few minutes, but the orbit was not complete. At the same time, signals were received and the ground station was taking action."

In January 2019, Iran announced that its satellite Payam, which collects environmental data from Iran, failed to enter orbit.

_

In accordance with the principle of openness and transparency, Iran announced the launch in advance, and the news was released a few hours before the launch. The news was also released as soon as the launch failed to reach orbit.

Although Iran failed to launch a satellite, it still released a video of the launch.

Locals near Zahedan city (south-east of Iran) published a few  photos. According to local reports, these debris had fallen after a loud sound of explosion.

Security deputy of Sistan and Baluchestan governor: possibility of falling debris of Safir-2-e-Zafar-1 rocket in Zahedan

Date of publication: Wednesday 09 February 1398, at 12:36

Mohammad Hadi Marashi said: The origin of a fearsome sound in the area of Zahedan is outside the province and we are investigating the details.

Following the release of some news about the fearsome sound reported in the district of Zahedan, our correspondent said that he was a conversation with security deputy of the Governor of Sistan and Baluchestan, who responded, saying that he replied: The origin of this is outside the province, and we are investigating the exact details.

Marashi added: In preliminary investigation it is possible that the sound heard and the falling parts on the ground were related to the rocket stages separated from the Safir-2 e-Zafar-1 launch.

He stressed: these debris fell in the the country's suburban district and there is no risk for the citizens.

PeeD, post: 12079259, member: 164846 Wrote:Again premature shut down or too low thrust of the second stage, like the last time.
Did one of the two turbopumps fail? Or one of the four motors did a safety shut down? A software error that shut off the second stage?

No Saman thrid stage was present, they wanted to keep it simple.

Maybe the R-27 venier motor is simply not suited for that long vacuum operation, as it should be significantly longer than on the Safir. Did the extension nozzle skirt fail due to overheating? Because that can't be well simulated on earth.

Wrong, official video published shows the Saman-1 upper stage, performing the final spin up orbital insertion!

_

Targeted: 530 kilometers and a speed of 7'400 meters per second
Achieved: 540 kilometers and a speed of 6'500 meters per second

This simply means that the upper stage's fuel was totally consumed but the wrong way, the Saman-1 upper stage peaking 10 km too high at the expense of a loss of speed of 900 meters/second.

One of the most frequent cause of failure in trying an orbital insertion when playing with space simulation video games such as Kerbal space!

This could happen if the upper stage is firing slightly off the optimal direction (we see it with catastrophic ending last year with the Indian Chandrayaan lunar lander).

And that engine cannot simply be shut and restarted the following orbit, because it is solid and not liquid fueled! You only have one shot.

Mission's rating

The Iranian Safir-2 carrier rocket has been successfully launched twice. The failure occurred with the Saman-1 upper stage. The launch of Iran’s Zafar-1 observation satellite was thus rated at 95% successful.

3. Ground track of the Safir-2-e-Zafar-1 rocket.

Conclusion

It only requires 5% of correction, and Iran will surely succeed in its first upper stage orbital insertion next Khordad (May-June) with the back-up satellite Zafar-2.

Needless to remind that this upper stage though looking like a toy right now because of its smaller size, is key in mastering Roll and Attitude Control System (RACS), that will be required in all future advanced missions ranging from solid propellant rocket, advanced geosynchronous insertions, and of course manned spacecrafts! Call it Post Boost Vehicles (PBV) if militarized. Again core component in any nuclear deterrent.
