I didn't see it on the ESA news item. Thanks. The three CubeSats are : - Ncube II It contains an automated identification system (AIS) used to receive GPS signals. Ncube II was developed by Norvegian universities. - UWE-1 The main objective of UWE-1, is to conduct telecommunication experiments related to the optimisation of an internet-related infrastructure for space applications. It was developped by a German university. - XI-V Its primary mission is the demonstration of newly-developed solar cells in space. It was developped by the Intelligent Space Systems Laboratory (ISSL) of Tokyo. More details on : http://www.esa.int/SPECIALS/sseti_express/SEMN9Z708BE_0.html Rakhir |

As I understand it - XI-V is one of the development models for XI-IV (which emailed me lovely earth pics every now and again ) - but with a better, 320x240 camera.
Of the three - UWE has been detected fine, NCube2 may have had a beacon signal detected, no news from XI-V yet. Strangely, NCube 1 was a failure, but they've taken it's engineering model camera and adapted it for SSETI itself - 1280x1024 images with approx 100m/pixel resolution. Doug |

Doug Do you have any of those Earth images available to show us? I like to keep track of the home planet now and then. -------------------- "After having some business dealings with men, I am occasionally chagrined,

http://www.space.t.u-tokyo.ac.jp/cubesat/index-e.html has a few
to be honest, they're terrible, but it's the thought that counts Take enough of them... |

SSETI Express in safe mode due to an undervoltage caused by battery charging problems.
http://www.esa.int/esaCP/SEMWD7638FE_index_0.html Signals from XI-V and UWE-1 have been successfully received at their respective ground stations. Ncube2 students are still struggling to receive the first life signs from their satellite. http://www.esa.int/esaCP/SEMSV5638FE_index_0.html Rakhir |

2 for 3 on cubes isnt bad actually - given that they cost less than the average projects accounting error
Sad for the Ncube guys though - this will be their second lost cube Doug |

With Clyde Space now having announced a space-rated EPS for the CubeSat Kit, we have a more complete overview of the available masses and volumes for missions that base their satellites on our hardware. Here are some interesting numbers:
Structural masses (i.e. the masses of the complete empty structures of our CubeSat Kits, including all fasteners): 1U (10x10x10cm): Total for 1U solid-wall: 251g Total for 1U skeletonized: 166g 3U (10x10x30cm): Total for 3U solid-wall: 521g Total for 3U skeletonized: 321g FM430 Flight Module (C&DH and COM processor): 81g Microhard MHX-series transceiver: 66g Solar Panel Clips: 9g Clyde Space EPS (includes Li-Poly battery, estimated): 250g So excluding payload, antennas and solar cell panels, a 1U skeletonized chassis + FM430 + MHX transceiver + Clyde Space EPS comes in at 572g, and uses up roughly the lower 45mm of the internal volume in the structure. So that means that you have roughly 400g for the antenna(s), solar panels and payload, and room for the payload inside a volume of roughly 96 x 96 x 40mm. The real killer -- mass-wise -- is the Solar Panels themselves. Just the bare PCBs (in 0.062" / 1.5mm thickness) weigh 30g each. So 180g just to be able to mount your solar cells to panels on all six sides. Dropping to 0.031" (0.75mm) PCBs saves you nearly 100g (10% !) of mass of the satellite. I noticed in this thread some discusson of the 2U (10x10x20cm) CubeSat. We've built and delivered 1U and 3U (solid-wall and skeletonized) units to customers. Haven't yet received an order for a 2U (or a 0.5U or a 1.5U), but all of these are easily implemented within our architecture. Hope this helps, -------------------- ______________________________________

Incredible, amazing, astounding!!! I have no words to explain my excitation when I've read this subject! So, it mean that anybody can build a 10 cm cube sized satellite?! It's incredible, I never have heard this adventure. It's so ... surealistic! A few days ago, I planned (just for fun), to build a micro-spacetelescope (mini-hubble in other word ). After, the launch will be did by Ariane5. But, If I have a good understanding of the Cubesat story, it will be cheaper by using the Space Shuttle? So, is ti possible to have more details on the how-to of the Cubesats, I'm very very very interest. -------------------- |
