Land Launch Zenit booster

The problem-plagued Zenit launch vehicle returned to flight on Saturday with the successful launch of the Israeli Amos-4 communications satellite from the Baikonur Cosmodrome in Kazakhstan. The 3.5-ton satellite, which was built by Israel Aerospace Industries for Israeli operator Spacecom, will deliver Ka- and Ka-band communications to the portions of the Middle East, Russia and south and east Asia.

This is the first successful flight of the rocket since the failure of a Sea Launch Zenit-3SL on Feb. 1. The launch vehicle crashed into the Pacific Ocean shortly after take-off when its first stage failed, taking the Intelsat 27 satellite down with it.

The Zenit launch vehicle, which has a success rate of just over 85 percent, was originally intended for multiple uses. Four Zenits were attached to the core of the giant Energia launch system designed to lift the Buran space shuttle into orbit. Zenits were also designed to fly separately as a replacement for the Soyuz booster for manned flights and as a satellite launcher.

Russian, Ukrainian Rockets Prone to Failure in Recent Years

Comments
Another fine day for Russia's space program. A Proton crashes with three GLONASS satellites.

Another fine day for Russia’s space program. A Proton crashes with three GLONASS satellites.

The spectacular crash of Russia’s Proton rocket on Tuesday — with the loss of three navigation satellites — was simply the latest in a series of launch failures that have bedeviled the Russian and Ukrainian space industries over the last 30 months.

The table below shows a tale of woe that began in December 2010 and has resulted in the loss of 15 spacecraft and cost the heads of the Russian space agency Roscosmos and launch vehicle builder Khrunichev their jobs.

Zenit Cleared for Return to Flight as Sea Launch Completes Accident Investigation

Comments

sea_launch_zenitBern, Switzerland, June 3, 2013 (Sea Launch PR) – Sea Launch AG has announced that the Failure Review Oversight Board (FROB) issued its final summary report of findings on May 31, following its review of the investigation into the cause of the January 31, 2013 failed launch attempt of the IS-27 spacecraft.  It had been previously reported that the FROB concluded that the failure was isolated to the Zenit 3SL 1st stage hydraulic power supply unit (BIM) with no other contributors identified.

Corrective actions are expected to be complete on the existing flight units in the June/July time frame and do not involve any design changes to the flight hardware.  The corrective actions focus on additional standalone inspections and testing of the BIM prior to installation into the Zenit 1st stage engine compartment.

Review Board Identifies Cause of Sea Launch Failure

Comments

sea_launch_zenitInvestigators have identified the cause of the failure of a Sea Launch Zenit launch vehicle at the end of January:

“The investigations isolated the failure to the Zenit-3SL first stage hydraulic power supply unit (BIM) used to pressurize the RD-171M main engine gimbal actuators. No additional contributors to the failure were found. The BIM failed approximately 3.9 seconds into the flight due to the abnormal performance of the pump that’s function is to pressurize the hydraulic oil supplied to the RD-171M main engine gimbal actuators. The pump failure was the result of contributing factors associated with a pump manufacturing process that proved difficult to control.”

Energia Pledges ‘Unfailing Commitment” to Failure-Prone Sea Launch

Comments

sea_launch_zenitMOSCOW, Russia and BERN, Switzerland – February 6, 2013 (Sea Launch PR) – S.P. Korolev Rocket and Space Corporation “Energia” (“RSC Energia”) spoke out today about its unfailing commitment to the long-term success of the Sea Launch program following the launch failure of Intelsat 27 spacecraft on February 1, 2013. RSC Energia has been the leader and the operator of the Sea Launch program since 2010.

In a statement, the General Designer and the President of RSC Energia, Vitaly Lopota said:

“We profoundly regret about the last week’s loss of the Intelsat 27 spacecraft. Many people worked hard to build the spacecraft, the launch vehicle and support the launch campaign. As we have been working in the space industry for over 65 years we continuously strive for perfection and reliability in everything that we attempt, but sometimes we fall short. The ocean-based launch system, Zenit launch vehicle and upper stage Block DM are a trusted means of payload delivery which combines the best in rocket-building technology and processes of recent decades. The launch failure is being investigated and analyzed. Its findings will be announced in the near future.”

Boeing Sues Sea Launch Partners for $356 Million

Comments

sealaunchBoeing has filed suit against its Sea Launch partners, alleging they failed to pay it more than $356 million owed after the Sea Launch joint venture went into bankruptcy in 2009.

The lawsuit, filed in U.S. District Court in Los Angeles on Friday, targeted RSC Energia, a company partially owned by the Russian government, and two Ukrainian state-owned companies, PO Yuzhnoye Mashinostroitelny Zavod and KB Yuzhnoye.

Sea Launch Puts Intelsat 27 Satellite into the Drink

14 Comments

The first hint of trouble came when the Sea Launch webcast suddenly cut out less than a minute after launch of the Zenit-3SL booster.

Was there some problem with the streaming? Or was it something more serious?

The latter.

Sea Launch AG announced today that approximately 40 seconds after liftoff of the launch of the Intelsat 27 spacecraft, all telemetry was lost indicating a loss of mission. The spacecraft, built by Boeing Satellite Systems was launched on a Zenit-3SL launch vehicle from the equator on the ocean-based Odyssey launch platform, positioned at 154 degrees West longitude.

Sea Launch will establish a Failure Review Oversight Board to determine the root cause of the incident and will provide additional information, as it becomes available, on the Sea Launch website at: www.sea-launch.com.

The failure marks a major setback for the company, which is majority owned by Energia Overseas Limited. The company uses Ukrainian-built Zenit-3SL rockets that are launched from an ocean-going platform that is towed to the equator.

Sea Launch had made four successful launches since it emerged from bankruptcy in 2011. The company has launched 35 times since 1999, with three failures and one partial failure.

 

Sea Launch Rocket Cleared in Launch Anomaly Investigation

Comments

sea_launch_zenitPALO ALTO, California and BERN, Switzerland– Dec. 19, 2012 (Sea Launch-SS/L PR) – Space Systems/Loral (SSL) and Sea Launch AG (Sea Launch) today announced that the Independent Oversight Board (IOB) formed to investigate the solar array deployment anomaly on a satellite launched in the spring of 2012 has successfully reached a unanimous conclusion.

The IOB, which was comprised of three highly regarded industry experts, worked with a comprehensive team of engineers from both SSL and Sea Launch to conduct an exhaustive investigation of data from the launch vehicle, the spacecraft, and interactions between the two.  Extensive data provided by Sea Launch were instrumental in achieving the findings which led to the investigation’s positive conclusion.

Independent Board Formed to Investigate Sea Launch Anomaly

Comments

PALO ALTO, CA and BERN, SWITZERLAND (SS/L & Sea Launch PR) — Space Systems/Loral (SS/L) (NASDAQ: LORL) and Sea Launch AG today announced the formation of a three person Independent Oversight Board to oversee the ongoing investigation into the root cause of an anomaly on a recently launched satellite. The Independent Oversight Board will be made up of impartial industry experts, nominated by the two companies.

The Independent Oversight Board will guide the joint SS/L-Sea Launch investigation team, which has been working together for several weeks to collect and analyze data with the objective of determining the root cause of damage to one solar array on an SS/L 1300 satellite that was launched on May 31, 2012 on a Sea Launch Zenit-3SL vehicle.
