That thing leapt off the pad like there was something a-comin' after it and it didn't dare to look back...

press conf now beginning on NASA TV. at a confortable 8 AM here in Europe (yes, we were mostly sleeping during the launch itself...) I confirm, Paolo! After picture-perfect launch, in the press conference they told about safe-mode due to a reaction wheel issue... let's hope they will solve soon! PS: this image is fantastic! http://spaceweather.com/gallery/full_image..._1378531705.jpg -------------------- I always think before posting! - Marco -

Thanks for posting the video, Astro0; just got home from work & immediately came here to look for same!
And what Gordan & oDoug said...that thing scoots. Talk about a bat out of hell. Nice little booster. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Hi,
The NASA Social media event for the launch and mission of LADEE was a fairly intense two days. NASA did a great job of not running us beyond our limits, but filling our days with educational activity. We heard about many topics in addition to LADEE flight and science. Pix are up on G+, although without captions. https://plus.google.com/photos/102180409349...875210826437601 https://plus.google.com/photos/102180409349...879400957736705 A first reflection on the whole experience can be found here. https://plus.google.com/1021804093492001763...sts/YxPAWcGqHdy In depth study notes (as I like to call more technical [g+ length] posts), will take me a year to dig into. But will be coming on G+. John |

Update on reaction wheel problem via Twitter:
@NASALADEE's reaction wheels were successfully brought back on-line. Get the latest as LADEE heads to the moon at http://www.nasa.gov/ladee |

Oh, it's definitely different from radio alright. About 4-5 orders of magnitude different. The far higher frequencies of light mean a far smaller beamwidth than a typical radio link, so they have to use spatial searching algorithms. See this video (cued up to the right moment) for a very brief discussion of this. https://www.youtube.com/watch?v=03BN7_4N0yQ&t=38s Thanks for the links! I thought there had to be some kind of active aiming refinement. BTW: I saw the launch, from northern Massachusetts, over 360 miles away. CP |

In her LADEE coverage, Emily Lakdawalla states that the Lunar Dust Experiment (LDEX) has heritage from Cassini CAPS (Cassini Plasma Spectrometer). I wonder if that is correct. CAPS measures the energy and electrical charge of particles such as electrons and protons and LDEX is an impact ionization dust detector. Emily probably mixed it up with Cassini's CDA (Cosmic Dust Analyzer).

Emily probably mixed it up with Cassini's CDA (Cosmic Dust Analyzer). Yes, I recall that the LDEX and NMS instruments started from previous work. The NMS is very close to the instrument on CASSINI.

Ooops! It appears a frog may have given its life for the conquest of space:

the LADEE mission has been extended one more lunar day (28 Earth days) and the probe will crash on the Moon "on or around April 21, 2014"
