| NASA get going on Nano-Sats |
| 2008-04-25 |
| NASA said today it would team with m2mi to develop very small satellites, called nanosats which weigh between 11 to 110lb, for the development of telecommunications and networking services in space. NASA says large groups of nanosatellites can be grouped in a constellation, that will be placed in low Earth orbit to offer new telecommunications and networking systems and services.NASA and m2mi will develop what they call fifth generation telecommunications and networking systems for TCP/IP-based networks and related services. Nanosatellites will be produced using low-cost, mass-production techniques, according to m2mi. "The constellation will provide a robust, global, space-based, high-speed network for communication, data storage and Earth observations," said m2mi Chief Executive Officer Geoff Brown Hmm, know any intelligence agencies that might need such a thing in the face of chinese and russian ASATs? The cooperative effort will combine NASA's expertise in nanosensors, wireless networks and nanosatellite technologies with m2mi's unique capabilities in software technology, sensors, global system awareness, adaptive control and commercialization capabilities. Fifth Generation technology, or 5G, incorporates VoIP, video, data, wireless, and an integrated machine-to-machine intelligence layer, for information exchange and use, NASA said. Took them long enough... I and an R&D group broached this idea about 10 years ago, and pushed it 5 years ago inside the intelligence/aeospace community. We called them "cheap sats". We were met with a collective yawn, since the IC and Big Aerospace is wedded to the One Big Multibillion-Dollar satellite way of doing things. Like the one we just shot down because it failed, and is probably leaving a big gap in intelligence coverage. /SITYS. Ive been harping on them for years here. /continues banging drum in hopes that the DoD and IC wake up |

| #11 Lest we fergit, MSM > the polymers and compunds, etc. used in manufactur new supermaterials are predomin OIL-BASED, ERGO WE CAN'T DEV OR DEPLOY ANY "CHEAP SATS" OR "NANO-SATS", ETC. ADVANCED TECHS BECUZ THE WORLD IS SUPPOS RUNNING OUT OF OIL TO MAKE SAID TECHS??? |

| #10 Bangalore: India's space agency will launch a cluster of ten satellites onboard a polar satellite launch vehicle from the Satish Dhawan space centre at Sriharikota, about 90 kilometres from Chennai. The launch rocket will carry the latest version of remote sensing satellite Cartosat-2A, an 83 kilogramme mini satellite, and eight foreign nano-satellites into polar orbit. The launch is scheduled for Monday morning. |

| #9 I read an interesting bit on clearing space debris with "a big ball of goo". A rocket is launched that when it reaches altitude, exudes a lot of sticky foam, forming a large ball around it. It normalizes the temperature of the goo by rotating in sunlight. Then it intentionally collides with smaller objects laterally instead of head on, and they stick to the goo. It uses an irregular orbit to intersect a lot of space junk before burning up in the atmosphere. |

| #8 100-300# and beach ball sized is what we were touting. There were (are?) launch vehicles that can loft that type of load into low earth orbit from under the wing of a high flying B52. |

| #7 :-) AFAIK, the Chinese have little or no assets to protect in space. It looks like most of their policy revolves around nukes, attacking neighbors, or defending the homeland. And probably without much help from central command. Don't really need much in the way of satellites to accomplish any of these goals. |

| #6 gorb: what, you mean a deliberate attempt to trigger a Kessler's Sydrome scenario? Even the Chinese wouldn't be so daft. I hope? |

| #5 All China would have to do would be to blow up enough satellites in orbit so that the volume of debris would cause a runaway chain reaction that takes out all the other sats. Alternate means of military communication will still be necessary. |

| #4 Oldspook and associates may have simply had the wrong term to describe their idea. "Cheapsats" isn't going to be liked by contractors or the managers of the contract managers. Nano-Sats sounds more profitable (even though calling something that weighs 100# 'nano' is a stretch). |

| #3 If we can gang together small optics on the earth to get higher resolution into space, It would make sense to have smaller spy sats to get better resolution from space to earth. Lets see what the company name is on your pen... |

| #2 Well, at least it is progress in the right direction. |

| #1 Much like the fastest computers in the world are no long the bing honking mainframes, but instead are clusters of smaller processors and computers tied together, so clusters can be applied to satellites. What sucks is that it took this long for them to finally realize that small cheap clusters of common component satellites can and will outperform the big multifunction platforms. Clustering is the FM here. ANd it makes them cheaper, smaller, easier to launch (and thus quciker to launch), and a lot less vulnerable to ASATs - you have to kill significant numbers of the cluster, not just one big satellite. And replacements could be quickly lofted. |
