According to foreign media reports, groups of machine spiders make spaceships or 3D printed satellites in space orbit. This is not a dream or science fiction, but may soon become a reality. The American Cable Unlimited Company, backed by NASA, recently entered into a cooperation agreement with Laura Space Systems, a US commercial satellite company, to jointly develop robot spiders. This peculiar machine spider will be able to create parts of various space systems directly in space using 3D printing technology.
Once the "SpiderFab" program is successful, there will be a large group of machine spiders busy in space, they can print out a variety of giant space system structures through 3D printing equipment and effectively assemble them.
This approach can help us create extremely large space systems, such as solar arrays and football-sized antennas that are ten or even hundreds of times larger than they are today.
The research and development program is called the "SpiderFab" program. According to experts, the plan is to first launch a machine into the space orbit to test whether it can print parts and assemble the overall structure, including solar panels, antennas, sensors and other components of the spacecraft or satellite. However, the ultimate goal of this program is more sci-fi. If the development is successful, there will be a large group of machine spiders busy in space, they can print a variety of giant structures through 3D printing equipment and effectively assemble them. By then, satellites, spacecraft and other equipment will be able to be built directly in space, helping humans to make larger spacecraft or satellites flying in Earth orbit.
The "brain" of this "smart spider" is made by the cable-free company in Washington, DC. Cable Unlimited has recently signed a cooperation agreement with Laura Space Systems, a US commercial satellite company, to develop robotic spiders with space 3D printing capabilities. Firmamentum, a subsidiary of Cable Unlimited, will test its "Trusselator" technology in Laura Space Systems' "蜻蜓" program. The “蜻蜓†program will test the construction of communication satellites in orbit, while the “Trusselator†technology will mainly manufacture lightweight frame trusses for supporting solar panels, antennas and sensors.
"Trusselator" technology will create high-performance support structures through 3D printing technology and automated assembly technology.
Dr. Robert Hoyt, CEO of Firmamentum, said, “The 蜻蜓 program provides us with an excellent opportunity to showcase space manufacturing technology,†said Dr. Matteo Jenna, chief technology officer of Laura Space Systems. "The development of next-generation communications satellites and space systems will rely primarily on advances in manufacturing technology." At this time, it is unclear when the two sides will conduct the test.
In order to enter the Earth's orbit, existing satellites must fold themselves and hide in the protective cover to prevent the temperature from being overheated and burned or damaged by the resistance. To make satellite parts in space, you only need to compress the spiders and raw materials into the rocket and send them into space. As early as 2013, Hoyt introduced this space manufacturing technology. “The raw materials needed to make these important parts in orbit, such as fibers, polymers, etc., can be compressed into a very compact form, packaged into a smaller, lower-cost launch medium. On the track, the machine The spider manufacturing system will process these raw materials to create extremely large structures that will help us create antennas or solar arrays that are ten or even hundreds of times larger than today. These devices will be able to be even wider. Space missions in the field provide greater energy, greater bandwidth, higher resolution, and higher sensitivity."(Editor)
