That will be 13 years after the SLS, which will have its first flight in 2017. China seems content to plod along.

You are right but wrong

SLS block I takes off in 2017/2018, but it "only" has a payload of 70 tons to LEO

SLS block II (with the comparable 130 ton payload LEO) OTOH will fly sometime between 2020 and 2030 (no formal date as of yet). So the difference is actually far smaller

In fact this site says block II will fly no earlier than 2030... So we may end up seeing two 130 ton LEO rockets do their first flights within a few years of each other. LM-9 might even fly earlier than block II SLS depending how things pan out

"SLS Block 2, which would not fly until after 2030 at the earliest, would be a Block 1A, potentially with a fifth RS-25E engine added to the core, topped by a new full-scale Large Upper Stage (LUS). LUS would be powered by one to three J-2X engines, but neither engine choice nor number of engines was fixed. Also not fixed was the basic stage construction or its propellant loading. Concepts called for LUS, which would only be used to reach LEO, to hold as much as 210 tonnes of propellant when three J-2X engines were used.."

Hence my pessimism for SLS. It's a Relic form the Days When Big ( Government in house ) Space was the only choice. with the Current maturity level of American Private, I feel more efficient competitive model could be put in place.

But at least there's a secondary program in place, better than having no SLS program at all.

People's Online Daily said:
BEIJING, Jan. 11 -- The service module of China's unmanned test lunar orbiter successfully decelerated which allowed it to enter an 8-hour orbit on Sunday, according to the Beijing Aerospace Control Center.

Following instructions from the center, the service module conducted the braking at around 3 a.m. and entered the 8-hour elliptical moon orbit with a perilune of about 200 km and an apolune of about 5,300 km.

The spacecraft has sustained balanced energy and is in a sound condition, according to the center, adding that the center exercised timely and stable control and tracing of the service module and relevant tests had been carried out smoothly.

The module will make its second and third braking in the early hours of Jan. 12 and 13 respectively to enable it to enter the target 127-minute orbit for tests to prepare for the next lunar probe mission, Chang'e-5, said center's chief engineer Zhou Jianliang.

The test lunar orbiter was launched on Oct. 24. The service module was separated from the orbiter's return capsule on Nov. 1, and the return capsule returned to Earth on Nov. 1 after circling the moon during its eight-day mission.

...and here's another report from earlier in the week:

Chinese space controllers are placing into Moon orbit the service module used for the country’s circumlunar test flight last November.
After releasing a test return capsule, the service module is headed for Moon orbit after loitering at Earth-Moon L2.

Slated to return to the Moon’s orbit mid-month, the service module has departed a temporary position at the Earth-Moon second Lagrange Point (L2).

According to the State-run Xinhua news agency: “It was the first time for a Chinese spacecraft to reach the L2 point, and the service module completed three circles around the point, expanding probe missions,” said Zhao Wenbo, vice director of China’s State Administration of Science, Technology and Industry for National Defense (SASTIND).

As of Monday, January 5th, the service module was over 276,000 miles (445,000 kilometers) away from Earth and roughly 35,418 miles (57,000 kilometers) from the Moon.

According to ground controllers, the service module contains support systems used for spacecraft operations and they reportedly are operating smoothly.

Earlier reports noted that a camera system is onboard the service module, designed to assist in identifying future landing spots for the Chang’e 5 mission that will return lunar samples back to Earth in the 2017 time frame.

The service module now en route to the Moon was separated from a test lunar orbiter return capsule on Nov. 1, with that capsule returning to Earth under parachute after successfully making a round-trip to the Moon during an eight-day mission.

The successful America private space company basically consist of one company SpaceX, all the others are abysmal failures. And SpaceX is successful primarily because it focuses on the most profitable segment of the space launch business. Kind of like how UPS and Fedex take on the USPS. But the big dinosaur such as Lockheed and Boeing still provide necessary national space capabilities in unprofitable segments, so the government have to throw them a bone to keep in business as well.
Beside the "private" alternative to SLS such as space fuel depot still involve high risk unproven engineering solution compare to the proven solution of a big rocket such as SLS.

Guys, his is a thread about the Chinese Space Program...not about the US program or its parts (ie. SLC). We have a separate thread for NASA and other space programs. Please take the SLC and other NASA related discussions there.

Thanks.

Helium3 here we come, hopefully in my life time.

China intends to mine the rare isotope, Helium-3 from the moon in an attempt to solve the world’s energy crisis.


According to Chinese State Media, China’s lunar orbiter has

into orbit around the moon. The spacecraft, dubbed the Change’e 5, will next perform a soft landing on the surface of the moon. It’s mission is to collect four pounds of rock and soil samples before returning to Earth.

China first landed a robotic lander on the moon on December 14th, 2013, when its Chang’e 3 spacecraft’s Yutu rover touched down successfully. When it did, Yutu’s arrival marked the first soft-landing on the satellite by a manmade spacecraft in over 37 years.

China’s next lunar step? China intends to build a mine on the moon to harvest Helium-3, a rare helium isotope. Scientists believe that mining Helium-3 from the moon may be the energy miracle the world has been waiting for. According to Ouyang Ziyuan, chief scientist of the Chinese Lunar Exploration Program, the moon is rich with Helium-3. Ziyuan says that mining the moon for the isotope could solve the world’s energy problems by providing renewable energy through nuclear fusion.

Whereas nuclear fission is the splitting of atoms to create energy, nuclear fusion is fusing

lighter atoms into a larger one to achieve a similar effect. Though nuclear fission doesn’t normally occur in nature, nuclear fusion occurs naturally in stars. The energy produced via nuclear fusion is three to four times greater than the energy produced by nuclear fission.

Matthew Genge, a scientist and lecturer at the Faculty of Engineering at the Imperial College in London, says that utilizing Helium-3 allows nuclear fusion to produce a tremendous amount of energy without the excess of radioactive waste produced in nuclear fission reactions. Nuclear fusion does not produce any extra neutrons. The interesting thing is that it wouldn’t take much Helium-3 to get the job done.

Scientists say that a mere 40 tons of Helium-3 harvested from the moon, (an amount that could be carried in the cargo bays of two space shuttles), could power the entire United States for over one year at its current energy consumption.

Helium 3 is rare on Earth because the atmosphere and magnetic field which surround the planet prevent any Helium 3 from landing on the surface. The Earth’s moon, however, contains vast quantities of the isotope that have been dumped there by solar winds.

China’s proclamation that it will provide enough Helium-3 to power the Earth for the next 10,000 years was met with curious optimism, a quantifier of doubt, and more than a little fear. Some wonder if China is the only country to mine the Moon, would that make for a Helium-3 monopoly?

China is the only one going to the moon these days, however. The

As far as the weight goes 40 tons of He3 would fit in the cargo bays of two space shuttles but when we look at the volume, and add the weight and volume of the dewar flasks to carry them to Earth liquid and at some 270 degrees Celsius below freezing water ....

Process it on the moon with He3 processing plant before shipping it back to Earth.
