PARIS — Even as the global economy struggles to recover, investment in space activities is flying high. The overall public expenditure in the sector — approximately $70 billion today — has been steadily increasing, projected to reach $80 billion in the next few years. And the commitment is not just growing deeper, but also wider: More than 70 different countries have invested at least $10 million in space programs, double the number from just 10 years ago.
But the motivation is more than economic: The investments in space are also driven by that most human of desires to explore. Countries know that no other kind of mission can compete with the adventures into space in the attraction exerted on the public imagination. Nothing else — except for sport, perhaps — can offer such a visible success for a nation than explorations into space. Between the U.S., China, India, Japan, South Korea, Russia and Europe, 14 different missions on or near the Moon, 13 Mars-related missions, as well as others of asteroids and other planets of the Solar System are planned for the coming years.
Much has been made about the many cuts proposed by the federal budget submitted this month by the new U.S. administration of President Donald Trump. But NASA remained virtually untouched, maintaining a fixed budget, mainly focused on what the Trump administration has defined a priority: further space exploration. And while the proposal seems to confirm the NASA project launched by the Obama administration to send humans to Mars by the 2030s, the most notable new focus is on an old destination: the Moon.
The first Chinese lunar roving vehicle, Yutu, — part of the Chang'e 3 mission — boasting a 150-meter altitude range, reached a record of permanence of 31 months on the moon before shutting off last August. The Chang'e mission had achieved the first soft landing on the moon after 40 years (the last one was achieved by the Soviet Union in 1976) with a robotic lander the Jade Rabbit (Yutu) robot. The Chinese ambitions for the moon are notable, and in the coming years include a series of missions aimed to prepare the arrival of astronauts ("taikonauts"), as well as a subsequent construction of a lunar base.
The desire to be back on the Moon is not only about science.
And U.S. plans? A few weeks ago, the Trump administration asked NASA to assess the possibility of a return trip to the Moon for two astronauts, with a projection date of 2019. If successful, it will be the first travel in deep space — that is to say past the international space station — in the 45 years since the last Apollo mission in December 1972. NASA has also announced this month its plans to move ahead with plans to construct a human outpost in cislunar space to be deployed in parallel with the International Space Station.
But no less consequential are the private initiatives. Elon Musk's high-profile SpaceX program aims to launch two private citizens for a space trip around the Moon by the end of 2018. If SpaceX will respect the deadlines, beating NASA, this will be not only the first human mission beyond the Earth orbit, but also the first mission privately funded.

Then, there is prime Musk rival, Amazon founder Jeff Bezos, who is full-steam ahead with Blue Origin, where the space vehicle currently in development, the New Glenn, will be launched as a plane in cislunar space, between the Earth and Moon. Bezos recently presented a white paper to NASA leadership to propose the development of an Amazon-like commercial delivery service to transport goods, experiment materials and housing modules to the Moon by the middle of the next decade.
"It is time for America to return to the Moon — this time to stay," Bezos wrote.
The United Launch Alliance, meanwhile, has also presented its Cislunar-1,000 vision, aimed at having 1,000 people living and working in the space by 2045.
Why the Moon? The scientific interest is mainly linked to its soil, aged around 3 to 4.5 billion years. Except for Mercury, almost inaccessible for us, the Moon is the only place where an inestimable treasure on the evolution of the solar system has been preserved.
But the desire to be back on the Moon is not only about science. Being able to set foot on Mars, not to mention permanent colonies built some 140 million miles away, is still only a dream. Risks are extraordinarily high and the technology needed to make it possible far from developed. The Moon, instead, is reachable: about a three-day trip away. The technological progress and the experience gained in the last decades have led us within reach of establishing permanent human colonies. This would result in tourism as well as rare resources extractions. The Moon also has another advantage: It is a project that can be realized within the timeframe of politics, as the resources needed to take 239,000 miles can be projected in the orbit of an electoral mandate. The next giant step for humanity is looking closer every day.

With loans and solar panels from China, the massive solar park has been opened a year and is already powering the surrounding areas. Now the Chinese supplier is pushing for an expansion.
CAUCHARI — Driving across the border with Chile into the northwest Argentine department of Susques, you may spot what looks like a black mass in the distance. Arriving at a 4,000-meter altitude in the municipality of Cauchari, what comes into view instead is an assembly of 960,000 solar panels. It is the world's highest photovoltaic (PV) park, which is also the second biggest solar energy facility in Latin America, after Mexico's Aguascalientes plant.
Spread over 800 hectares in an arid landscape, the Cauchari park has been operating for a year, and has so far turned sunshine into 315 megawatts of electricity, enough to power the local provincial capital of Jujuy through the national grid.
It has also generated some $50 million for the province, which Governor Gerardo Morales has allocated to building 239 schools.
Abundant sunshine, low temperatures
The physicist Martín Albornoz says Cauchari, which means "link to the sun," is exposed to the best solar radiation anywhere. The area has 260 days of sunshine, with no smog and relatively low temperatures, which helps keep the panels in optimal conditions.
Its construction began with a loan of more than $331 million from China's Eximbank, which allowed the purchase of panels made in Shanghai. They arrived in Buenos Aires in 2,500 containers and were later trucked a considerable distance to the site in Cauchari . This was a titanic project that required 1,200 builders and 10-ton cranes, but will save some 780,000 tons of CO2 emissions a year.
It is now run by 60 technicians. Its panels, with a 25-year guarantee, follow the sun's path and are cleaned twice a year. The plant is expected to have a service life of 40 years. Its choice of location was based on power lines traced in the 1990s to export power to Chile, now fed by the park.

Chinese want to expand
The plant belongs to the public-sector firm Jemse (Jujuy Energía y Minería), created in 2011 by the province's then governor Eduardo Fellner. Jemse's president, Felipe Albornoz, says that once Chinese credits are repaid in 20 years, Cauchari will earn the province $600 million.
The Argentine Energy ministry must now decide on the park's proposed expansion. The Chinese would pay in $200 million, which will help install 400,000 additional panels and generate enough power for the entire province of Jujuy.
The park's CEO, Guillermo Hoerth, observes that state policies are key to turning Jujuy into a green province. "We must change the production model. The world is rapidly cutting fossil fuel emissions. This is a great opportunity," Hoerth says.
The province's energy chief, Mario Pizarro, says in turn that Susques and three other provincial districts are already self-sufficient with clean energy, and three other districts would soon follow.
