Chinese satellites heading to moon fail to reach orbit after rocket falters
Beijing, Mar 15: A pair of Chinese satellites failed to reach a planned orbit on their way to the moon after experiencing abnormalities, a rare setback for Beijing's high-profile space programme.
The satellites, known as DRO-A and DRO-B, were launched on Wednesday evening from the Xichang Satellite Launch Centre in the Sichuan Province, the launch centre said in a press release on Thursday.
They were carried by A Yuanzheng-1S (Expedition-1S) upper-stage aircraft, attached to a Long March-2C carrier rocket, it said.
The first and second stages of the rocket operated normally, while the upper stage encountered an abnormality during flight, causing the satellites to fail to enter the preset orbit accurately, it said.
The relevant disposal work is currently underway, state-run Xinhua news agency reported, citing the launch centre.
The plan was for the two satellites to head towards the moon and enter a distant retrograde orbit (DRO).
From there, they would fly in formation and work with DRO-L a third satellite that was successfully placed into low-Earth orbit by a Jielong 3 rocket last month to test laser-based navigation technologies between the Earth and the moon, known as cislunar space, the Hong Kong-based South China Morning Post reported.
The DRO orbit is at a high altitude, tens of thousands of kilometres above the lunar surface. It is highly stable, allowing spacecraft to remain on track for a long time without using fuel, and is an advantageous waypoint for research and exploration, according to Chinese scientists.
Long March rockets have been integral to China's space ambitions, including moon missions.
China's manned space station is currently in orbit.

According to Surya, it happened after the Centre's intervention.
The MP staged demonstration with an empty trunk to convey that the state government's promises are empty trunk.
The protest was also in response to Deputy Chief Minister D K Shivakumar's statement that Surya is an empty trunk who is more active on social media and not on the ground.
Speaking to PTI after being detained, Surya said, "Just because we are asking for affordable public transport and accountability, the government is forcing arrest and detention. It's shameful."
He said that instead of providing roads, infrastructure and better amenities, the state government is "arresting" him.
Speaking to reporters, he also said, "Metro fare hike has been put on hold for the second time due to pressure from the Union government. The state government should release a white paper on the economic situation."
