Can anyone translate the two single-character labels within Sinus Iridum? Even better, is there anyone who can give a summary translation of relevant parts of the video?

Today is a BIG day. Today is the day when New Horizons will be exactly ONE BILLION KILOMETERS away from 134340 Pluto. The historic moment will be occurred on March 28 at 15:58:18 UTC (SCET w/o LT correction), when New Horizons's range rate relative to 134340 at -13.889 km/s, and relative to the Earth at -14.717 km/s. Yes, the probe is running toward both 134340 and the Earth right now.

The article only gives the first use of the new ion engine in 2015. It is unknown whether the 2015 mission is the asteroid mission.

I have the full text of the paper you quoted which dated July 2011. But I think Ouyang Ziyuan's presentation matches the latest report better. It is also known that a meeting was held in May 2012 on the design of the asteroid mission. Based on all these info, I think we could have an estimated launch time between 2015 and 2017, a flyby of 12711 Tukmit in August 2018, and 99942 Apophis orbit insertion in April 2020, Apophis departure in September 2020, orbit and landing on 1996 FG3 August–December 2023.

China's first dedicated asteroid mission will be powered by xenon ion engine. The engine has successfully tested in orbit on Shijian-9 satellite on November 7, 2012. The probe will visit three asteroids: make a flyby of the first and take pictures, orbit the second, and land on the third. According to earlier reports, potential targets include 12711 Tukmit, 99942 Apophis and (175706) 1996 FG3.

This is a guideline how you can apply for these datasets: http://www.clep.org.cn/index.asp?modelname...000&recno=6 (in Chinese)

Normal users can only download "processed data products" (level-3 datasets) by sign up at http://159.226.88.59:7779/CE1OutWeb/ . For those have cooperation with the program, they can apply for raw datasets (level 0,1,2).

As an enthusiast from China, NASA and the United States have disappointed me a lot. From the cancelled Jupiter Icy Moons Orbiter and Mars Telecommunication Orbiter, to the delayed Mars Science Laboratory and the dying Constellation Program... I have almost lost the confidence and patient.

But based on reports from various sources, I think China is serious this time. There will be a Mars Pathfinder-like small lunar rover in 2013, and a sample return mission in 2017. It is just amazing, even by NASA/JPL's standard.

And China so far has a good record to get things done on time.
