French engineers have designed a tiny ion motor that nano-satellites could use as a thruster to adjust their orbits.
Swiss engineers have designed a tiny ion motor that nano-satellites could use as a thruster to adjust their orbits.
The motor weighs only seven ounces, and could work on satellites as small as four inches cubed.
Up to now, it wasn’t possible to reduce the size of maneuverable satellites below a certain point because of the size of their large thruster engines. If it is now possible to provide nano satellites with thrusters, it will be possible to significantly reduce the cost, and more importantly, the payload weight, of satellites. And with a lower payload weight, it will be possible to create a market for smaller rockets, which are much easier to build and far cheaper.
This kind of news makes me more confident that the new commercial space industry truly has a future.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

This is great news! And it’s applicable to much more than earth orbital satellites… if we can get robotic spacecraft on the same exponential miniaturization curve as many other technologies the cost of robotic exploration could drop by several orders of magnitude over the next decades…
