Set for launch today:
http://www.esa.int/SPECIALS/GOCE/index.html Some interesting new technology here - half satellite half airplane! Well maybe mainly satellite, but an interesting concept that could have applications in other atmospheres, making lower orbiting feasible. |

Some interesting new technology here - half satellite half airplane! Well maybe mainly satellite, but an interesting concept that could have applications in other atmospheres, making lower orbiting feasible. Not least for Titan. I have to say I have a very soft spot for the concept of aerodynamic stabilization for ram-pointing coupled with electric propulsion. The very first conference paper I wrote (which I presented a couple of months after my 19th birthday at the IAF conference in Bangalore..) was about just that... Aerodynamic attitude stabilization for a small, low-orbiting, manoeuvrable satellite, (later published in Acta Astronautica, 19, 573-576, 1989) I since discovered that a few early satellites did exploit aerodynamic stabilization, albeit without ion thrusters or resistojets.. |
