Dime-Size Thrusters Could Propel Satellites, Spacecraft

Posted by in categories: energy, internet, satellites

CAMBRIDGE, Mass. — A new propulsion engine with dime-size thrusters could be used to propel a host of spacecraft, from small satellites to crewed ships designed for interplanetary exploration.

The new propulsion engine, called Tile, could serve as an efficient and lightweight way to keep constellations of small satellites in orbit. Spaceflight companies — including OneWeb, Boeing and SpaceX — want to launch hundreds of thousands of these small satellites to provide broadband internet to everyone around the globe. And because several Tiles can be connected to produce more power, the engine has the potential to propel astronauts to Mars, according to Accion Systems, the company that designed Tile.

“Our technology starts on a nanometer scale, and then we can array that and scale that up to serve satellites,” said Natalya Bailey, CEO of Accion Systems. Bailey described the propulsion engine to an audience here at the New Space Age Conference at the Massachusetts Institute of Technology’s (MIT) Sloan School of Management on March 11.

Estonia’s mission to the moon could revolutionise space travel

Posted by in category: satellites

Estonia will receive a 100th birthday gift next year that will be truly out of this world – as part of the country’s centenary celebrations in 2018, ESTCube will unveil its second satellite while its team embarks on a mission across Estonia to educate young people about opportunities within the space industry.

ESTCube-2 will be three times larger and far more complex than its predecessor, ESTCube-1, which turned Estonia into an unlikely space nation when it entered orbit in 2013.

ESTCube-2 is planned to blast off in 2019 and will operate at approximately 680 kilometres (423 miles) above Earth, which is almost twice as high as the International Space Station. However, the satellite is being designed to boldly go much further.

Recycling Space Junk for a LunarBase

Posted by in categories: robotics/AI, satellites, sustainability

It costs $80k to send a Nano- Satellite into space! To send the materials to build a lunar base is going to be expensive!

This week it was announced that NASA found a forgotten satellite in Lunar Orbit, which got me thinking about an idea to recycle existing Space Junk in the construction of an International Lunar Base with cost savings. We could use a modified version of my Google Deepmind NEO tracker to source the Space Junk and the ideas listed below to capture and redirect the Space Junk.

Massive commercial space push and a variety of new robotic capabilities could self supporting and rapidly growing space economy

Posted by in categories: economics, robotics/AI, satellites

Several companies will collectively be launching about 20,000 satellites over the next few years. SpaceX, OneWeb, Telesat, O3b Networks and Theia Holdings — all told the FCC they have plans to field constellations of V-band satellites in non-geosynchronous orbits to provide communications services in the United States and elsewhere. So far the V-band spectrum of interest, which sits directly above Ka-band from about 37 GHz to the low 50 GHz range, has not been heavily employed for commercial communications services.

* SpaceX, for example, proposes a “VLEO,” or V-band low-Earth orbit (LEO) constellation of 7,518 satellites to follow the operator’s initially proposed 4,425 satellites that would function in Ka- and Ku-band.

Researchers remotely control sequence in which 2-D sheets fold into 3D structures

Posted by in categories: bioengineering, biotech/medical, nanotechnology, satellites, solar power, sustainability

Inspired by origami, North Carolina State University researchers have found a way to remotely control the order in which a two-dimensional (2-D) sheet folds itself into a three-dimensional (3D) structure.

“A longstanding challenge in the field has been finding a way to control the sequence in which a 2-D sheet will fold itself into a 3D object,” says Michael Dickey, a professor of chemical and at NC State and co-corresponding author of a paper describing the work. “And as anyone who has done origami — or folded their laundry—can tell you, the order in which you make the folds can be extremely important.”
