The faulty pump caused the rocket to fail in mid-flight – and delayed China’s ambitious plans to put a new space station in orbit around Earth, send a sample return mission to the moon, and even begin exploring the surface of Mars.But as Friday’s successful launch showed, Chinese engineers seem to have fixed the rocket’s critical flaws.“After more than two years’ effort … the research and development team has overcome challenges in engine technology. [We] solved the problem, “Wang Yu, who commanded the mission, told China News Services, according to the (South China Morning Post. China’s big ticket to the solar system takes off
The version of the Long March 5 that launched on Friday can heave payloads weighing up to 51, (lbs) 25 tonnes) into low-Earth orbit, or just a couple hundred miles above Earth. That’s half the payload capacity ofSpaceX’s new Falcon Heavy rockets
, which can haul about (**********************************************************, (lbs) 64 tonnes) into orbit, but that’s plenty to secure China’s ambitious future in space over the next few decades.Other versions will carry smaller payloads farther, such as (**************************************************************, (lbs) tonnes) to geosynchronous orbit – where a satellite can remain stationary above a point on Earth – and (*******************************************************************, ******************************************************************** (lbs (8.2 tonnes) out to the moon. (This makes the Long March 5 capable of launching the planned Chinese Space Station, a lunar sample-return mission, a a Mars rover, and a space telescope.While these missions are valuable in terms of science, economic development and so on, they are also important to Chinese leadership in terms of international prestige & domestic support, “Andrew Jones, a correspondent for Space News,Tweetshortly before launch. “Another failure would be seen as embarrassing. The tension will be astronomical tomorrow.”Which is why the rocket mission’s success is all the more important to China and its future. ************************************
