The engineering company Mouser Electronicspublished video of a satellite launcher being 3-D printed on the International Space Station (ISS) Wednesday.

EngineerAndy Filo designeda device to help astronauts launch tiny satellites weighing less than 100 grams in zero gravity. Scientists can use these satellites tomonitor disasters, cosmic rays and solar coronal events.

WATCH:

Filo developed the device as part of a design challenge to develop useful technology for astronauts.

Mouser brought together engineers, students and makers from around the world in this exciting design challenge. All the designs were excellent, but in the end there was one design that stood above the rest, Glenn Smith, President and CEO of Mouser Electronics, said in a statement. The heart of this challenge was innovation, and Andys femtosatellite-launching device embodies forward-thinking design.

Mouser chose Filos femtosatellite project from 242 entries, and then digitally-transmitted it to the ISS. The worldsfirst off-world commercial manufacturingprinter 3-D printed the design in April.

The ISS 3-D printer manufactured its first objects in space in November 2014. It works by building layers of heated plastic to create objects, effectively making a working machine shop capable of building virtually any tool in space. Engineers on the ground can transmitdesign files for any tool to the printer.

This capability decreases the cost and difficulty of sending tools to the ISS. It can take months or even years to ship specialty tools to the space stationdepending on the launch resupply schedule. Future deep space exploration missions will almost certainly carry similar printers as resupplying tools from Earth may be impossible.

A series of achievements in Chinas space program over the last 12 months have set the stage to start construction of the countrys first space station in 2019, a year later than previously scheduled, officials said Friday.

Since 2016, we have successfully launched the Long March 7 carrier rocket, the Tiangong 2 space lab, the Shenzhou 11 manned spacecraft and the Tianzhou 1 cargo spacecraft, said Wang Zhaoyao, director of the China Manned Space Agency. The four flights achieved success in Chinas manned space program, and laid a solid foundation for the building and long-term operation of a space station.

The Long March 7 rocket is vital for launching supply ships, and eventually crews, to Chinas future space station. It has now flown two times successfully.

The Tiangong 2 orbital module launched in September 2016, welcoming two Chinese astronauts on the Shenzhou 11 spacecraft in October for a one-month expedition, the countrys longest human spaceflight to date.

The heavy-lifting Long March 5 rocket not mentioned by Wang took off on its maiden flight in November. The powerful launcher is needed to place heavy space station modules into orbit.

And the Tianzhou 1 robotic cargo craft launched on a Long March 7 rocket April 20, linked up with Tiangong 2 two days later, and accomplished Chinas first in-space refueling test on Thursday.

The rapid-fire launch campaign has bolstered confidence that the key components needed for Chinas space program will be ready when construction begins, officials said.

A core module, named Tianhe 1, is scheduled for launch in 2019 to begin assembly of the space station. Two support sections will launch by 2022 to complete construction of the space station, which officials said should be operational for at least 20 years.

Three-person crews will live on the space station for three-to-six months, officials said. The finished outpost will have a mass of more than 60 metric tons, about one-seventh that of the International Space Station, and comparable to the mass of NASAs Skylab station in the 1970s.

With crew and cargo transport ships docked, the stations mass will rise to around 90 metric tons, or 200,000 pounds.

From June of last year to yesterday, four planned flight missions of the space lab phase were all completed, Wang said in a press conference Friday. In retrospect, we have taken note of many important achievements and successful experiences that are worth learning.

Chinas latest mission, Tianzhou 1, demonstrated the countrys ability to resupply and refuel the future space station. Weighing more than 28,460 pounds (12,910 kilograms) at liftoff, the robotic cargo craft was the largest and heaviest spacecraft ever launched by China.

Tianzhou 1 will remain docked with the Tiangong 2 space lab until around late June, then spend three months conducting standalone experiments before re-entering Earths atmosphere.

In the next phase, the cargo spacecraft will remain docked with the space lab as they orbit together, Wang said. The cargo spacecraft will also undock and fly alone and try different approaches to improve in-orbit refueling technology. After that, the cargo spacecraft will land under control in a designated area in the South Pacific Ocean, while the space lab will remain in space for further exploration.

The solar-powered Tianzhou 1 spacecraft will detach from Tiangong 2 and attempt a fast rendezvous profile on another approach to the space lab in the coming weeks, according to Wang. The rendezvous trajectory will mimic the path future cargo missions will take, allowing for delivery of supplies and fuel the same day of launch.

The current rendezvous and docking process needs two days for preparation, Wang said. If the technology of autonomous fast rendezvous and docking technology succeeds, we only need six-and-a-half hours for rendezvous and docking between two spacecraft. It will greatly enhance our work efficiency.

Russian Progress supply ships and Soyuz crew ferry craft often dock with the International Space Station around six hours after liftoff.

Chinese officials say the Tianzhou resupply missions will carry up to 14,300 pounds 6.5 metric tons of cargo to the planned orbital complex. The fuel transfer system will deliver up to 4,600 pounds 2.1 metric tons of liquid propellant to the stations propulsion system.

The payload ratio and the amount of propellant refueling are on a par with current international standards for space cargo transportation systems, if not being ahead of them, Wang said.

The Tianzhou cargo carrier is bigger than the International Space Stations current visiting vehicles, capable of ferrying more equipment than Russias Progress, the U.S.-built commercial Cygnus and Dragon, and the Japanese HTV spaceships.

As the last (test) mission before the space station is built, the mission is significant in serving as a link between past and future, Wang said.

Tianzhou means heavenly vessel in Chinese.

The simulated cargo aboard Tianzhou 1 represents the equipment a three-person crew would need for one month in space, officials said. The payloads include crew provisions, water tanks and oxygen and nitrogen vessels designed to replenish the space labs breathable atmosphere.

While no crews will be present during Tianzhou 1s mission, the freighter carries several experiments, including one on non-Newtonian gravity, according to Chinese media reports.

Zhao Guangheng, chief designer of the space labs utilization system, said the non-Newtonian gravitational experiment will verify the performance of a high-precision electrostatic suspension accelerometer.

The accelerometer performance index has reached the international advanced level, which will provide important technical support for our country to carry out research of basic space physics, weak force measurement and gravity gradient measurements, Zhao said Friday.

Other research investigations will study the proliferation and differentiation of human embryonic stem cells into germ cells to gather data on the possibility of human reproduction in space, Chinas state-run Xinhua news agency reported.

The stem cells and embryos of mice are also on-board Tianzhou for an experiment into how animals and humans could regrow lost tissues and organs, Xinhua said. Researchers also sent up an experiment to test out a new medicine for osteoporosis.

Wang told reporters Friday that Tianzhou 1 will also deploy an experimental CubeSat later in its mission and test other technologies.

An advanced navigation, guidance and control device and new domestic-made components will be tested in orbit, Wang said. An active vibration isolation technology will also be tested. Those tests will be carried out one-by-one.

Future Tianzhou spacecraft could carry replacements for large station components, like a solar array wing, service other satellites in orbit, and be repurposed as a deep space tug for missions to the moon, according to Yang Baohua, vice president of the China Aerospace Science and Technology Corp., the Chinese spacecrafts lead contractor.

Asked whether Tianzhou supply ships could fly to the International Space Station, Yang replied that Chinas exclusion from the program a policy enshrined in U.S. law means the spacecraft is not technically compatible with the ISS docking mechanisms.

Because of this, the technological standards, such as the interfaces, are yet to be unified, and that is why the docking cannot be fulfilled in the short term, Yang said. However, the aerospace staff in China is willing to work on behalf of the International Space Station, because space exploration, the manned endeavor, should be a cause shared by the entire human race in peace.

Wang Zhaoyao from Chinas human spaceflight agency said the countrys engineers plan to make their spacecraft fit with a variety of possible destinations.

China is enabled by both of its technologies and competence to transport freight to the International Space Station, Wang said. However we need, specifically, to take a step further to solve problems with different interfaces, which has drawn considerable concern from the international community. In the past few years, the country has been engaged in standardizing the interfaces of its spacecraft, especially in regard to manned spaceflights. Its like the diversity of cell phones which cannot be recharged because of unmatched outlets.

Since Chinas first astronaut flight in 2003, crews have performed automated and manual docking maneuvers and conducted a spacewalk.

Wang said the modules for Chinas space station are undergoing preliminary testing, and officials have signed cooperation agreements with the United Nations Office for Outer Space Affairs to provide experiment opportunities for scientists from all nations, including developing countries.

Zhao, who is responsible for experiments on the space station, said the orbiting research complex will host science and engineering investigations across a range of disciplines.

He identified life science, biotechnology, microgravity fluid dynamics, combustion science, materials science, basic physics, astronomy and astrophysics, space environment monitoring, Earth observation and technological demonstrations as key areas for experiments on the Chinese space station.

Bethesda's sci-fi adventure game Prey is out on Friday, May 5, and its launch trailer has been released to celebrate.

The video shows off some of the abilities you'll be able to develop on board your spaceship, Talos I, as well as showcasing the numerous enemies that will be hunting you down as you go. Take a look at the full trailer above.

We also get a brief glimpse at the player-character's brother, Alex Yu. Alex is the boss of Talos I, and developer Arkane said recently that the space station will change depending on your relationship with the character.

Today, we learned what's included in Prey's day one patch. The update includes a load of bug fixes, as well as support for English dialogue no matter which region your game is from.

Addressing concerns that the game might be buggy on some platforms, Arkane has stated that it "doubled" its thoroughness in working on the title's PC version after Dishonored 2--from the same company--suffered from a multitude of problems on the platform. Many players seem to be impressed by the game's Opening Hour demo, though that is only available on consoles.

The PC version's minimum and recommended specs were also revealed recently, and the game's soundtrack is available now.

Prey is a reimagining of the 2006 original, and a replacement for the canceled sequel to that game that was in development at Human Head Studios.

The new title is seen by some as a spiritual successor to the 1994 game System Shock, while we also think it's been inspired by BioShock.
