Should we return to the Moon? While Elon Musk, Mars One, and even NASA have their sights set on the Red planet, many think that the Moon is a better option for space exploration .
The European Space Agency (ESA) is one - they just released a new video stating that the Moon is an important and crucial step in mankind's future.

"In the future, the Moon can become a place where the nations of the world can come together to understand our common origins, to build a common future, and to share a common journey beyond. A place where we can learn to move onwards into the solar system," ESA explains in the video "Destination: Moon" .

ESA envisions future manned missions to the far side of the Moon - also known as the dark side of the Moon because it never faces the Earth (though it isn't shrouded in darkness at all). This alien landscape is a rugged terrain, scarred with billions of years worth of impact craters, including one of the largest impact craters in the solar system, the South Pole-Aitken basin.

Scientists think the crater formed around 4 billion years ago. Inside of this 8.1-mile-deep crater, certain parts are shrouded in perpetual, freezing darkness, but at the crater's rim, shown below, are high, mountainous peaks that bathe in almost-constant sunlight. It's here, on these lunar mountains that ESA plans to send robots and eventually humans.

By sending future missions to the Moon we will be able to answer questions like:

  • Is there water elsewhere on the Moon?

  • If so, how much?

  • Where did it come from?

  • And what can it teach us about the origins of water and life on Earth?


If the Moon proves to have an abundant store of water under it surface, then future human generations can use the hydrogen and oxygen atoms for rocket fuel.

The European Space Agency (ESA) has proven that its project to 3D-print a base on the Moon is possible. In a latest video the agency shows how 3D-printing robots may be used to build the base using lunar material.

The ESA started investigation of the lunar base possibility in 2013, working alongside its industrial and architectural partners. The creation of the reliable semi-spherical structures on the surface of the moon could be fulfilled within the next 40 years, and 90 percent of the materials needed would be derived from the moon itself.

latest details of the new concept, which is, however, still "firmly on the drawing board," were discussed at a conference this week at ESA's technical center in Noordwijk, the Netherlands.

An amazing photo taken by a NASA probe shows Saturn and its large moon Titan shining as pretty crescents in deep space.

The two cosmic bodies were imaged by the Cassini spacecraft, which has been exploring the Saturn system for about 10 years. The image -- released on Monday (Nov. 3) -- was captured as the robotic ship was flying about 1.1 million miles (1.7 million kilometers) from the ringed wonder on Aug. 11, 2013, according to NASA. Some of Saturn's ring plane can even be seen in the black and white image.

"More than just pretty pictures, high-phase observations -- taken looking generally toward the sun, as in this image -- are very powerful scientifically since the way atmospheres and rings transmit sunlight is often diagnostic of compositions and physical states," NASA officials said in an image description. "In this example, Titan's crescent nearly encircles its disk due to the small haze particles high in its atmosphere scattering the incoming light of the distant sun."

China has completed its first return mission to the moon with the successful re-entry and landing on Earth of an unmanned probe, state media reported.

The probe, Chang’e 5-T1, landed safely in northern China’s Inner Mongolia region, state news agency Xinhua said, citing the Beijing Aerospace Control Centre.

Xinhua said the probe, dubbed “Xiaofei” (little flyer) on social media, took “some incredible pictures” of the Earth and the moon. It is the first trip around the moon and back since US and Russian flights of the 1970s, 40 years ago.

Prior to re-entering the Earth’s atmosphere the unnamed probe had been travelling at 11.2 kilometres per second (25,000 miles per hour), a speed that can generate temperatures of more than 1,500C (2,700F), the news agency reported.

To slow it down scientists let the craft “bounce” off Earth’s atmosphere before re-entering again and landing.

The probe’s mission was to travel to the moon, fly around it and head back to Earth, said the the state science and technology agency, Sastind. The module went 413,000km from Earth at its furthest point.

The mission was launched to test technology to be used in the Chang’e-5, China’s fourth lunar probe, which aims to gather and return samples from the surface in 2017.

The military-run space project has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.

China currently has a robotic rover, Yutu (Jade Rabbit), on the moon. It landed on 14 December 2013 and completed parts of its mission before grinding to a halt on 25 January 2014 due to equipment failure.

The mission launched on October 23 and is taking an eight-day roundtrip flight around the Moon and is now journeying back to Earth. The mission is a test run for Chang’e-5, China’s fourth lunar probe that aims to gather samples from the Moon’s surface, currently set for 2017. Chang’e 5T1 will return to Earth on October 31.

The test flight orbit had a perigee of 209 kilometers and reached an apogee of about 380,000 kilometers, swinging halfway around the Moon, but did not enter lunar orbit.

ISRO plans second mission to Mars in 2018

The Indian Space Research Organisation (ISRO) is planning to launch second mission to Mars with a lander and rover to carry out more experiments on the red planet.

The proposed plans come after the Indian space agency has successfully placed its unmanned Mars Orbiter Mission spacecraft to the Martian orbit in September.

ISRO satellite centre director Shiva Kumar was quoted by IANS as saying: "We plan to launch a second mission to Mars in 2018, probably with a lander and rover, to conduct more experiments for which we have to develop new technologies.

"We will be able to take the Mars-2 mission after launching the second mission to the moon (Chandrayaan-2) in 2016 with our own lander and rover, which will help us develop a separate lander and rover for the red planet."

The agency is looking to launch the programme in 2018 as the missions to Mars can be launched at two year intervals.

ISRO intends to have fully operational heavy rockets ready by then to carry communication satellites weighing around 3t into the geo-stationary orbits around the earth.

In line with this plans, the agency has developed the geo-synchronous satellite launch vehicle (GSLV Mark I-III) to launch heavier communication satellites.

GSLV Mark-III is scheduled to take its first partial test flight in early December.

ISRO chairman Radhakrishnan was quoted by The Hindu as saying that the test flight will lead to a 'future workhorse vehicle that will stay with us for many years'.

Tests will be conducted on unmanned crew module of the three-stage launch vehicle, to evaluate heating during its re-entry and its behaviour in the crucial space phase.

To the moon and back: Lunar mission tests China's space program

China launched an experimental spacecraft early Friday that is scheduled to orbit the moon before returning to Earth, a first for the country's ambitious space program and considered a precursor to a planned mission to the moon.

The unmanned spacecraft was launched by a Long March 3C rocket from the Xichang Satellite Launch Center in Sichuan, western China, state media said.


It is China's first lunar module capable of returning to Earth and the mission's main technical challenge will be making sure the spacecraft slows down enough to re-enter Earth's atmosphere safely.


Too fast and it could overheat or become difficult to track and control, Hu Hao, chief designer of the lunar exploration program, told The China Daily.


It is expected to take around a week to fly around the moon. The spacecraft will end its mission by landing on the grasslands of Inner Mongolia.


The mission tests technology that will be used in a more ambitious launch, scheduled to take place in 2017, when an unmanned lunar probe will go to the moon, collect soil samples and return home.


Chinese astronauts have made five manned space flights on a series of Shenzhou "Divine Vessel" modules, with the latest mission in 2013 completing a successful manual docking with the Tiangong-1 space station.


Last December, China put a lunar rover -- known as the Jade Rabbit -- on the moon but it has been plagued by mechanical troubles, the China Daily said.







On course for the moon?


Joan Johnson-Freese, a professor at the U.S. Naval War College, said the lunar orbiter marks a step forward in the capabilities needed for a potential manned lunar program, which while under discussion hasn't been officially approved yet.


"It's significance is not only in demonstration of technical abilities, but in a continued political will to achieve its space goals over long periods of time — which is what China has that the U.S. currently lacks."


While the United States has pulled back its space program, other countries are trying to match or surpass China's accomplishments in what some observers have called an Asian space race.


In September, India became the first Asian country to send an orbiter around Mars.


Political symbolism


China sent its first astronaut into space in 2003 and has made rapid advances in the intervening decade.


Despite this, its space program is still yet to achieve capabilities reached by the U.S. and then Soviet Union decades ago, says James A. Lewis, director and senior fellow at the Washington-based Center for Strategic and International Studies.


With little economic or military advantage, its value, he says, lies in how the space program shapes China's perception of itself -- a conspicuous display of national power and wealth that asserts China's return to confidence and authority.


"We could ask if China is following an outdated recipe for superpower status," he writes in a blog for the University of Nottingham in the UK.


"In terms of the global effect of the manned program, there might be some truth to this. But for the domestic audience that is the chief concern of China's leaders, the space program produces invaluable results."
