SpaceX celebrated a successful rocket launch on Saturday, sending a reused cargo spacecraft to resupply the International Space Station in orbit approximately 250 miles above the earth. But Elon Musk’s California-based company kept quiet about the spacecraft’s stowaway — a Chinese science experiment now installed in the Space Station. It’s a sign that aerospace’s swiftly-advancing private sector may have found yet another innovation: A way to evade the years-long ban on official cooperation in space between the United States and China. The Chinese experiment carried aloft by SpaceX’s Falcon 9 rocket will test how space radiation effects gene mutation, with potential ramifications for extended human space travel. It was designed by the Beijing Institute of Technology, who partnered with NanoRacks, paying the U.S. company approximately $200,000 to assist with transportation and data collection. It marks the first time a Chinese experiment has been conducted in the Space Station’s U.S. section, according to tech news site ARS Technica. International space cooperation these days, if not in the early years of the space race, is common, as it helps offset the extraordinarily high costs of technology and space travel. Russia and the United States jointly operate the Space Station, and NASA has signed a deal shelling out $490 million for Russia’s Soyuz space modules to deliver six U.S. astronauts to the space station. But cooperation has its limits: Congress banned bilateral cooperation between NASA and Chinese state-owned enterprises and Chinese citizens in 2011, citing national security risks. Rep. John Culberson (R-TX) upheld the ban after he became chair of the House subcommittee that funds NASA in 2014. “China’s space program is owned and controlled entirely by the People’s Liberation Army and the Chinese government have proven to be the world’s most aggressive in cyber-espionage,” Culberson said in an October 2015 statement. “I intend to vigorously enforce the longstanding prohibitions designed to protect America’s space program.” China’s space program, as with many state-owned Chinese firms from energy outfits to port developers, has close ties to its military. But the extent of such ties and even basic information about Chinese space programs, such as how much funding they receive, is uncertain due to lack of transparency. An even greater concern is technology transfer and theft. In 1998, a congressional investigation discovered that China had developed intercontinental ballistic missile systems incorporating U.S. technology originally offered to Chinese companies for commercial use. As a result, Congress shifted licensing requirements for all satellites and related technology to the State Department, which is in charge of approving commercial arms exports. For this launch, however, no State Department license was required, according to a person involved. SpaceX declined to comment on the licensing aspects of the launch. China’s space program is highly advanced and extremely ambitious. In 2013, China became the third country after the United States and Russia to land on the moon; the Jade Rabbit rover spent 31 months gathering data before shutting down. China has put two space laboratory modules into orbit and hopes to have its own full-size space station within the next decade. In January, the China National Space Administration announced plans to land a probe on Mars by 2020. NanoRacks took steps to prevent any technology transfer during the course of its partnership with the Chinese institute, according to the company, including isolating its research platforms to guarantee there was no interface between external researchers and the Space Station system. NanoRacks spokesperson Abby Dickes says these measures meant that the company did not need permission from the State Department for its partnership with Beijing Institute of Technology. Dan Huot, a NASA spokesperson, confirmed that no part of the project connected into the Space Station’s IT system, and that NASA properly notified Congress of the project. Commercial partnerships have “no ‘flags,’” NanoRacks CEO Jeffrey Manber told Chinese state news agency Xinhua. “I believe commercial is the pathway forward for greater cooperation with Chinese companies and educational organizations.”

The first Chinese science mission aboard the International Space Station will soon be ready to begin. On Saturday, June 3, SpaceX launched its refurbished Dragon capsule atop the Falcon 9 rocket, carrying scientific research equipment and experiments from China along with food and other essentials. The Chinese devices will be delivered to the space station on June 6, when the unmanned Dragon spacecraft is scheduled to dock with the ISS. The focus of China's first scientific mission aboard the ISS is the problem of space radiation and its effects on astronauts' DNA. Specifically, the mission aims to study the rate of DNA mutations in the space environment, according to Deng Yulin, project leader and life science professor at the Beijing Institute of Technology. As Deng points out, gene mutation is one of the biggest risks that astronauts face during space missions. This is because radiation levels are 10 times higher in space than on Earth, he explains. "The research team caught evidence of the gene mutation after the first experiment via Shenzhou-8 [launched by China in 2011], which proves the space environment can cause DNA mutation and biomolecular changes," said Deng in a statement. The current research project will continue that previous work aboard the ISS, where it is set to investigate whether space radiation and microgravity dictate a pattern of gene mutation, Deng stated. This experiment is the first Chinese-led research done on the U.S. side of the station. The project is expected to run for about 30 days aboard the ISS, after which the Dragon capsule will return the results back to Earth. Due to the nature of the research project, this endeavor could have important implications for long-duration human spaceflight. For the purpose of this experiment, the Beijing Institute of Technology teamed up with the American private company NanoRacks. The U.S. firm was paid about $200,000 to deliver the payload to the space station, as well as to collect data from the experiment and provide storage inside the company's racks. Apart from the SpaceX launch last weekend, China has also sent scientific equipment in space aboard its Tianzhou-1 cargo spacecraft earlier this spring. China's first cargo spacecraft, Tianzhou-1 docked with its orbiting space laboratory, known as the Tiangong-2, on April 22, after being launched into space inside the Long March-7 Y2 rocket. © 2017 Tech Times, All rights reserved.

Materials that reversibly trap water from air could provide a vital source of drinking water in areas where it is scarce, or offer energy-efficient air conditioning. But to be commercially viable, these materials need a large water capacity and low energy requirements during water adsorption and desorption. Now, Mircea Dincă and his research group at MIT report record-setting performance for water-trapping in a metal-organic framework (MOF) that may bring both applications closer to reality (ACS Cent. Sci. 2017, DOI: 10.1021/acscentsci.7b00186). Porous materials can spontaneously pull water out of the air even at low humidity if their pores are the right size and their interior surfaces are hydrophilic. To maximize water capacity, the pores must be spacious, but not so big that the trapped water condenses into liquid that permanently clogs them. At the sweet spot, the water adsorbs to the MOF’s pores and desorbs with modest energy input, explains study co-author Adam Rieth. “Both adsorption and desorption are very important,” he says. In the new study, the researchers worked with a group of MOFs that had previously been used for the reversible capture of ammonia, chlorine, and bromine gases. These MOFs have just about optimal pore size—around 2 nm—and are made with manganese, cobalt, or nickel ions bound to triazolate linkers. In ambient air, the interior surface is naturally hydrophilic. When testing the MOFs, the researchers found that water spontaneously enters the pores at as low as 28% relative humidity. At 30% relative humidity, consistent with night-time conditions in arid climates, the cobalt MOF adsorbed almost 90% of its own weight in water, approximately double that of the next-highest-performing known material. The researchers calculated that if the cobalt-containing MOF were used in a hypothetical adsorption heat pump, the trapped water could be stripped from the material at just 55 °C. This means the device could potentially be powered by waste heat from a car engine, for example. Bo Wang, a MOF researcher from Beijing Institute of Technology who was not involved in the study calls it a “great addition” to the field. “It’s a very thorough study and helps to guide the design of MOFs.” However, this study looked only at the MOF material. In a real-world setting whether for air-conditioning or water capture, the MOF would need to be part of a device that uses heat to release water and regenerate it. For instance, another research team recently reported a water harvesting device that used solar energy to regenerate the MOF (C&EN, April 17, page 8). The MIT team predicts that if used in the same device, the cobalt MOF would be able to deliver almost three times as much water per cycle. They are now working to test their MOFs in this context, Rieth said.
