Since the LRO passed its Mission Rehersal today and is on track to launch on Wednesday next week, it seems like a good time to start a thread about the launch.
http://lunar.gsfc.nasa.gov/launch.html From the link above, there will be a pre-launch webcast on Tuesday morning. The launch is scheduled for 3:51 PM EDT (12:51 PDT) which is 1951 GMT Wednesday June 17. [Corrected -- thanks Gsnorgathon!] When it actually starts sending back pictures, someone should probably start a separate thread, but I think it makes sense to have the launch discussion separate from both the Development and the Cool Pictures threads. --Greg |

About the speed trayectory of LRO/LCROSS from Earth toward Moon, I am still trying to learn and understand its evolution speed. However, I know that the minimum velocity required to escape from Earth gravity is around 11.6 kp/s and I have noticed thru the other source of information that the spacecraft was reducing its speed from 5 kp/s at about 35,000 km from Earth, 4kp/s even further from Earth. Then I tought that the LRO/LCROSS didn't reach the 11.6 kp/s to escape from Earth gravity in its way toward to Moon but at lower speed...
Then I realized the spacecraft speed will be reducing to the minimum speed until the Selene gravity captures it. Is that my tought correct? Thanks for any comments. |
