China launches its first rocket from mobile platform in sea
Beijing: China successfully launched a rocket from a mobile platform at Yellow Sea for the first time on Wednesday, sending two technology experiment satellites and five commercial satellites into space.
A Long March-11 solid propellant carrier rocket blasted off from a launch pad aboard a ship in the Yellow Sea off the coast of Shandong province at 12:06 pm (local time).
It is China's first space launch from a sea-based platform and the 306th mission of the Long March carrier rocket series, official media here reported.
China in recent years has emerged as a major space power with first ever mission to the dark side of the moon as well as manned missions besides building its own space station to be ready by 2022.
It is also a leading country in launching number of satellites from its launch stations on land.
Launching a carrier rocket from an ocean-based platform has many advantages over a land launch. The closer to the equator a rocket launch can get, the greater the speed boost it will receive. It reduces the amount of energy required to get into space and means that less fuel is required, state-run Xinhua news agency reported.
The launch site is flexible and falling rocket remains pose less danger. Using civilian ships to launch rockets at sea would lower launch costs and give it a commercial edge.
The seaborne launch technology will meet the growing launch demand of low inclination satellites and help China provide launch services for countries participating in the Belt and Road Initiative, Xinhua quoted Chinese experts as saying.
The two satellites, developed by China Academy of Space Technology, are expected to step up all-weather monitoring of ocean wind fields and improve typhoon monitoring and accuracy of the weather forecast in China.
Among the five commercial satellites, the two satellites, developed by China Electronics Technology Group Corporation, are China's first small satellite system based on Ka-band.
The Long March-11, developed by China Academy of Launch Vehicle Technology, is the only rocket using solid propellants among China's new generation carrier rockets. It is mainly used to carry small satellites and can take multiple satellites into orbit at the same time, the report said.

Parliamentary panel to summon airline executives, regulator over flight disruptions
New Delhi (PTI): A parliamentary panel is likely to summon top executives of private airlines and the civil aviation regulator over the mass cancellation of IndiGo flights that has left thousands of travellers stranded across the country's airports.
The Parliamentary Standing Committee on Transport, Tourism and Culture, chaired by JD(U) leader Sanjay Jha, is likely to seek an explanation from top executives of airlines and officials from the Directorate General of Civil Aviation (DGCA) and the Ministry of Civil Aviation about the cause of disruption in air services and possible solutions.
A member said the panel has taken serious note of the difficulties faced by thousands of passengers due to disruption in air services.
Even parliamentarians, who were in the national capital for the Winter Session, faced the brunt of flight cancellations by IndiGo and delays by other airlines, the panel member said.
Several MPs also received complaints from people about air fares shooting up due to the scenario.
Meanwhile, CPI(M) Rajya Sabha member John Brittas, who is not part of the standing committee on transport, has demanded setting up of a joint parliamentary committee or a judicial inquiry into the large-scale disruption of flights.
IndiGo cancelled more than 220 flights at Delhi and Mumbai airports on Sunday, as the disruptions entered the sixth day even as efforts were on to normalise operations.
The aviation regulator, DGCA, on Saturday sent notices to IndiGo CEO Pieter Elbers and COO and Accountable Manager Porqueras, seeking explanation.
In a statement issued on Sunday, IndiGo said the Board of Interglobe Aviation, its parent company, has set up a Crisis Management Group, which is meeting regularly to monitor the situation. The company's Board of Directors is doing everything possible to take care of the challenges faced by its customers and ensure refunds to passengers, it said.
