[LINK] On the latest Chang’e lunar missions of China

leave a comment »

The Planetary Society’s Emily Lakdawalla wrote about China’s exciting new plans for Moon exploration.

An article about Chang’e 4 appeared on the website of China Daily today, and it contains a small amount of news about China’s present and future lunar exploration plans. Thanks to @sinodefence on Twitter for the link and to scientist Quanzhi Ye for some help with translating the news.

It had already been reported that China planned to send Chang’e 4 (the backup model of the Chang’e 3 lander) to the lunar farside. The intent to land on the farside was announced on the Chinese Lunar Exploration Program website on December 2. The China Daily News article mentions launch dates, and they’re earlier than previously discussed. A communications relay satellite (based on the design of Chang’e 2) will be launched in June of 2018, and will take up a position at the Moon-Earth L2 point, where it will be able to see both the landing site and Earth. The lander will be launched at the end of 2018. There is still no official word on what the lander’s scientific payload will be, or even if it will carry another rover. Interestingly, the article mentions some kind of public involvement in the payload development. China already has experience navigating lunar orbiters to the L2 point. [. . .]

Guokr — a Chinese blog site that often hosts science-related content — posted a blog with a little more information about the planned Chang’e 4 mission. This is not an official source! The Guokr blog mentions the south pole-Aitken basin as a possible landing site.[. . .]

The China Daily News article also talks about “successful completion” of the Chang’e 3 mission. This does not mean the end of the mission, but rather an official statement that Chang’e 3 has been successful. Monthly contact with Chang’e 3 continues, although it’s not clear if it is still doing scientific observations. A review paper about Chang’e 3 recently appeared in the literature, which helped lunar mapper Phil Stooke update his maps of the Chang’e 3 landing site, likely for the final time. Here’s an overview, including the lovely names for the mini-craters observed by the lander during its descent:

[LINK] “European Space Agency Reiterates Its Plan to Build 3D Printed Base on the Moon”

leave a comment »

The Dragon’s Tales linked to this report suggesting the European Space Agency plans to use 3-D printing to build a base on the Moon.

For a while, the European Space Agency has been talking about the possibility of creating a base on the moon, using 3D printing for a large part of its construction. So far it’s been a lot of speculation, but this month the ESA reaffirmed that they are very serious about the plan – they intend to have a lunar base by the 2030s. At a recent symposium entitled “Moon 2020-2030: A New Era of Coordinated and Robotic Exploration,” the agency laid out plans for a series of missions, starting in the early 2020s, that will hopefully culminate in a human-occupied moon base.

The two-day symposium brought together more than 200 scientists and space officials from 28 countries to discuss what the ESA is calling a “comeback to the moon.” The plan is for a series of missions, beginning in the 2020s, that will start by sending robots to the moon, where they will communicate with astronauts back on Earth. The data gathered from these robotic missions will pave the way for humans to follow. Ultimately, the ESA sees a moon colony as a stopping point in the mission to get humans to Mars and to further explore the rest of the solar system.

[LINK] “China Plans Lunar Far Side Landing by 2020”

Universe Today’s Ken Kremer reports on China’s plans.

China aims to land a science probe and research rover on the far side of the Moon by 2020, say Chinese officials.

Chinese scientists plan to carry out the highly complex lunar landing mission using a near identical back up to the nations highly successful Chang’e-3 rover and lander – which touched down in December 2013.

If successful, China would become the first country to accomplish the history making task of a Lunar far side landing.

“The mission will be carried out by Chang’e-4, a backup probe for Chang’e-3, and is slated to be launched before 2020,” said Zou Yongliao from the moon exploration department under the Chinese Academy of Sciences, according to a recent report in China’s government owned Xinhua news agency.

Zou made the remarks at a deep-space exploration forum in China.

“China will be the first to complete the task if it is successful,” said Zou.
