    Arrow Palapa D (113.0E)



    Satellite: Palapa D

    PT Indosat Tbk, chose Thales Alenia Space to build and launch the Palapa-D satellite. Palapa-D, which launch is expected during second half 2009, will replace Palapa-C2 satellite which will expired in 2011 placed in slot 113º East.

    Based on Thales Alenia Space Spacebus-4000B3 platform, Palapa-D satellite will have larger capacity compared to Palapa-C2 satellite of which it has 24 standard C-band, 11 extended C-Band and 5 Ku-band transponders, with coverage of Indonesia, ASEAN countries, Asian countries, Middle East and Australia. Palapa-D satellite will have a launch mass of 4.1 tons, a payload power of 6 kW and service life time of 15 years.

    Indosat appointed Thales Alenia Space to build and launch Palapa-D satellite through a tender process in which Indosat invited several potential experienced manufacturers from domestic and international. Indosat based the appointment of Thales Alenia Space on its capability to meet Indosat's requirements and its ability to provide competitive and comprehensive communications solutions. Indosat and Thales Alenia Space have jointly selected Long March 3B as the launch vehicle for the Palapa-D satellite.

    The cost of building and launching Palapa-D project is between US$200 - US$300 million. Indosat will finance this Palapa-D satellite with company's internal and external resources.

    Palapa D to Put Into Orbit in August

    Indonesian teleco company PT Indosat Tbk plans to launch the Palapa D satellite by the end of August 2009, which will replace the Palapa C2 satellite whose orbital session will end in 2011.

    "By the end of August, we are designing to send forth the Palapa D satellite. But everything will depend on the weather," said Indosat Managing Director Harry Sasongko on Friday, August 14.

    "The satellite launch is a form of our commitment for our users that are mostly television broadcasters, VSAT service providers as well as other corporate users," said Harry.

    The satellite will orbit at 113 degrees East Longitude, which is still occupied by the C2 satellite.

    "The Palapa D satellite has wider scope and will be stronger than the Palapa C satellite. In addition, the Palapa D has more transponders than the palapa C," said Harry.

    Report has it that the Palapa D satellite will have 40 transponders, more in quantity that the Palapa C2 with 36 transponders.

    Chinese Rocket Launches Satellite to Wrong Orbit

    Breaking a 13-year streak of successful launches, a Chinese Long March rocket failed to deliver an Indonesian communications satellite to its planned orbit Monday.

    Carrying the Palapa D telecommunications satellite, a Long March 3B rocket blasted off from the Xichang launch base in southwestern China at 0928 GMT (5:28 a.m. EDT) Monday.

    The three-stage launcher, boosted by four liquid-fueled strap-on engines, flew as expected during the first few minutes of the flight.

    But a failure occurred about 20 minutes after liftoff as the third stage was scheduled to ignite for its second burn of the mission, according to the official state-run Xinhua news agency.

    The third stage is powered by two YF-75 engines fueled by a mix of liquid hydrogen and liquid oxygen, according to China Great Wall Industry Corp., the international marketing arm of the country's launch industry.

    The engines apparently completed the first of two burns to place the rocket and Palapa D into a parking orbit.

    Xinhua reported the third stage encountered problems during the second ignition, but it was not clear if the engines failed to fire or shut down early.

    "Experts are investigating," the Xinhua report said.

    The 41-foot-long third stage produces about 35,000 pounds of thrust in flight, first to send payloads into low-altitude parking orbits and then to propel spacecraft into egg-shaped geosynchronous transfer orbits.

    The stage, which is also used on other Long March rockets, has never been responsible for a launch failure before Monday, according to Chinese launch records.

    According to U.S. military tracking data, Palapa D is circling Earth on a path with a high point of about 13,150 miles, a low point of approximately 130 miles and an inclination of around 22 degrees.

    Palapa D's planned orbit was not published before launch. It is unclear whether the satellite will be able to reach its operational station 22,300 miles above Earth in geosynchronous orbit.

    The satellite was built by Thales Alenia Space of France for Indosat, an Indonesian telecommunications firm.

    Palapa D's C-band and Ku-band communications payloads were designed to cover a swath of territory stretching from Australia to India. The satellite had a life expectancy of 15 years.

    Television broadcasters and corporate customers were expected to use Palapa D's communications capacity.

    The satellite was ordered as a replacement for the aging Palapa C2 spacecraft launched in 1996. Palapa C2 is expected to cease operations in 2011.

    Indosat officials said in 2007 they invested between $200 million and $300 million for construction and launch of the satellite.

    Monday's launch marked the 12th flight of a Long March 3B rocket, which had successfully launched 10 times since its debut mission suffered a deadly accident in 1996.

    Attempting to launch a U.S. communications satellite, the rocket flew off course moments after liftoff and crashed into a nearby village, killing Chinese civilians.

    Since a different launch failure later in 1996, all Long March rocket variants had amassed 75 straight flawless flights in a streak spanning almost 13 years.

    China's workhorse rocket family includes seven derivatives to launch a wide variety of payloads, ranging from commercial and military satellites to scientific probes and piloted Shenzhou missions.

    Monday's anomaly could deal a blow to China's aspirations to gain a greater share of the global launch industry. The Long March 3B is the country's primary launcher for commercial missions.

    Chang Zheng-3B suffers third stage problem during Palapa-D launch

    From NASASpaceFlight.com

    The Chinese have suffered a problem during the launch of the Indonesian Palapa-D communications satellite via a CZ-3B Chang Zheng-3B (CZ3B-12) launch vehicle. The launch took place at the Xi Chang Satellite Launch Center, in Sichuan Province on Monday at 09:28 UTC, but failed to place the spacecraft in the required orbit – due to an issue with the CZ-3B’s third stage.

    The Palapa-D satellite was scheduled to replace the Palapa-C2 (23864 1996-030A) satellite – which is due to come to the end of its life in 2011 – at 113.0 degrees East. It is unknown at this time if the spacecraft can be saved, though this is unlikely.

    Latest reports from the Chinese State media – which appeared to undergo a news blackout for several hours after launch – claim the problem is related to a failure of third stage ignition.

    The new satellite was ordered to Thales Alenia Space in July 2007 and is based on the Spacebus 4000B3 platform – which has a larger capacity than the Palapa-C2. It is equipped with 24 standard C-band, 11 extended C-band and 5 Ku-band transponders, and will cover Indonesia, ASEAN countries, Asia, Middle East and Australia.

    Palapa-D has a launch mass of 4,100 kg, a payload power of 6 kW and a service life time of 15 years.

    The launch of Palapa-D is – or was as the case may be – part of a commitment drive by the Indonesian communications industry to provide services that include TV broadcasters, VSAT providers and other corporate customers.

    The satellite was set to be used to support other services such as cellular communications, fixed voice telecommunications and fixed data services. The cost for the development and launch of the Palapa-D is between US$200 million and US$300 million.

    China’s return to their launch manifest – after a four month lull – came via their most powerful vehicle in the fleet, the CZ-3B Chang Zheng-3B.

    The CZ-3B features enlarged launch propellant tanks, better computer systems, a larger 4.2 meter diameter payload fairing and the addition of four strap-on boosters in the core stage for additional boost during the first phase of the launch.

    The rocket is capable of launching a 11200 kg satellite to a low Earth orbit, or a 5100 kg cargo to a geosynchronous transfer orbit. The vehicle has a total length of 54.84 meters and a core diameter of 3.35 meters.

    The first launch of the CZ-3B took place on February 14, 1996 but ended in what is now known has the “St. Valentine’s Day Massacre”.

    That failure occurred when the first CZ-3B stage suffered a problem just two seconds after lift-off, resulting in the vehicle listing heavily off the pad. With no range safety on board, the vehicle flew almost sideways for around a minute, before nose-diving into a nearby town, killing an untold amount of people. Recently unearthed raw video (30mb) of the launch, impact, and the aftermath are available on L2.

    The first successful launch took place on August 19th, 1997 when the second CZ-3B orbited the Agila-2 ‘Mabuhay’ (24901 1997-042A) communications satellite. Palapa-Ds launch was the 13th use of the CZ-3B.

    This was the 119th launch for the Chinese, the 118th launch of a Chang Zheng launch vehicle and the 51st orbital launch from the Xi Chang Satellite Launch Centre.

    The Xi Chang Satellite Launch Centre is situated in the Sichuan Province, south-western China and is the country’s prime launch site for geosynchronous orbital launches.

    Equipped with two launch pads (LC2 and LC3), the centre has a dedicated railway and highway lead directly to the launch site. The Command and Control Centre is located seven kilometers south-west of the launch pad, providing flight and safety control during launch rehearsal and launch.

    Other facilities on the Xi Chang Satellite Launch Centre are the Launch Control Centre, propellant fuelling systems, communications systems for launch command, telephone and data communications for users, and support equipment for meteorological monitoring and forecasting.

    The first launch from Xi Chang took place at 12:25 UTC on January 29, 1984, when the CZ-3 Chang Zheng-3 (CZ3-1) was launched the Shiyan Weixing (14670 1984-008A) communications satellite into orbit.

    Indonesian satellite launched in China in normal state after failure to enter orbit

    From Xinhua

    XICHANG, Sept. 1 (Xinhua) -- Indonesian communications satellite Palapa D has been captured and is now able to conduct orbit maneuver, a few hours after an announcement that it failed to enter a preset orbit following its launch at 5:28 p.m. Monday at the Xichang Satellite Launch Center in southwest China.

    The satellite is in a normal state, its manufacturer, the French company ThalesAlenia Space, said late Monday night.

    The satellite was launched atop a Chinese-made Long March 3B rocket.

    The Palapa D satellite, owned by Indonesian satellite communications company Indosat, was supposed to provide satellite links and broadcasting services for Indonesia and other southeastern Asian nations.

    Indosat ordered the satellite from ThalesAlenia Space in 2007.

    Rocket hiccup no jam-up for China

    From China Daily Website

    The failure to put a satellite into orbit earlier this week is only one bump on a long road of successes, said a space expert.

    The setback occurred Monday when the third stage of a Chinese-made rocket failed to fire, causing the Indonesian telecom satellite Palapa D that it was carrying to miss its orbit.

    The rocket, called the Long March 3B, was launched at the Xichang Satellite Launch Center in Southwest China's Sichuan province, one of the country's two major sites for rocket liftoffs. It is China's main launcher for commercial missions.

    The mishap is the first glitch in a string of 75 successful launches for China's rocket program dating to October 1996, said Pang Zhihao, researcher and deputy editor-in-chief of the monthly Space International.

    "At more than 90 percent, China has as high a success rate as Russia, the US and Europe in launching rockets," he said.

    The Palapa D satellite, owned by Indonesian satellite communications company Indosat, was supposed to provide satellite links and broadcast services for Indonesia and other Southeast Asian countries.

    However, the satellite still has a chance to enter its preset orbit.

    The satellite's manufacturer, French company ThalesAlenia Space, said the satellite has been captured and is now able to maneuver.

    In 2001, the European Space Agency spent 18 months getting the Artemis telecommunications satellite into its target orbit after an unsuccessful launch from Kourou, French Guiana, in South America.

    "Though maneuvers may use much of the fuel in the satellites and shorten their life spans, it is better than giving up and having nothing left," Pang said.

    China Great Wall Industry Corporation, which provides the orbit delivery service, and ThalesAlenia both declined to comment Tuesday.

    A China Great Wall Industry staff told China Daily on condition of anonymity that the corporation is in talks with the Indonesian side to decide what actions will be taken.

    China experienced major setbacks between 1994 and 1996, but regained its international reputation after tightened quality control and a series of successes.

    Pang pointed out that launching a satellite is risky, and other countries have also experienced failures.

    Recent examples include a protective nose cone fairing on the US Taurus-XL rocket failing to separate during ascent, leading to the Orbiting Carbon Observatory, a pioneering satellite designed to map carbon dioxide concentrations, to crash into the ocean near Antarctica in February this year.

    South Korea also failed to send its satellite, carried by its first launch vehicle, into its target orbit on Aug 25.
