Iran says rocket launch failed to put payloads into orbit

Launch attempt was criticised by western powers negotiating with Tehran to revive 2015 nuclear deal

Iran said its attempt to launch three research devices into orbit on Thursday failed because the rocket was unable to reach the required speed.

The attempted launch, which came as indirect US-Iran talks take place in Austria to try to salvage a 2015 nuclear deal, drew criticism from the United States, Germany and France.

"For a payload to enter orbit, it needs to reach speeds above 7,600 [metres per second]. We reached 7,350," defence ministry spokesman Ahmad Hosseini said in a documentary about the launch vehicle broadcast on state television on Friday.

Iran, which has one of the biggest missile programmes in the Middle East, has suffered several failed satellite launches in recent years because of technical issues.

Washington says it is concerned by Iran’s development of space launch vehicles, and a German diplomat said Berlin had called on Iran to stop sending satellite launch rockets into space in breach of a UN Security Council resolution.

France said on Friday that the rocket launch broke UN rules and was "even more regrettable" because nuclear talks with world powers were making progress.

Iran's foreign ministry issued a statement rejecting the US, German and French criticism.

"Scientific and research advances, including in the field of aerospace, are the inalienable right of the Iranian people, and such meddling statements will not undermine the Iranian people's determination to make progress in this field," it said.

Tehran denies that its space activity is a cover for ballistic missile development or that it violated a UN resolution.

A UN resolution in 2015 "called upon" Iran to refrain for up to eight years from work on ballistic missiles designed to deliver nuclear weapons after an agreement with six world powers. Some states said the language did not make such a pledge obligatory.

Iran says it has never pursued the development of nuclear weapons and, therefore, the resolution does not apply to its ballistic missiles, which Tehran regards as an important deterrent and retaliatory force against the US and other adversaries in the event of war.

Iran launched its first satellite Omid (Hope) in 2009, and its Rasad (Observation) satellite was sent into orbit in 2011. Tehran said in 2012 that it had successfully put its third domestically made satellite, Navid (Promise), into orbit.

In April 2020, Iran said it put the country's first military satellite into orbit after repeated launch failures in previous months.

The United States imposed sanctions on Iran's civilian space agency and two research organisations in 2019, saying they were being used to advance Tehran's ballistic missile programme.
