QUOTE (Steve) At Meridiani, Opportunity is moving again. We've found a way to drive short distances with the IDD deployed... Stange that Steve put the words "short distances" in there. The drive to Victoria is anything but! Does that mean they are going to risk stowing the IDD properly for the long drive? Or just that they don't know yet that it's ok for longer drives as it's as yet untested? James |

QUOTE (The Messenger @ Jan 31 2006, 05:54 AM) Should LISA still be funded, if the current (S5) LIGO run continues to roll snake eyes? If we are certain we can achieve a couple of orders of magnitude of higher resolution I would say yes, but it seems to me that this would be a daunting challenge, in space.  Deja vu! - We've already had this conversation!   From this thread QUOTE (The Messenger @ Sep 6 2005, 03:28 AM) One more question about LISA - unless and until the current LIGO generation of gravity antenna detect ANY gravitational phenomena, should we be vesting in another experiment? IAOTO the waves do exist, but we may be searching with the wrong kind of antenna. QUOTE (jamescanvin @ Sep 6 2005, 11:17 AM) Well LISA will be serching in a completely different frequency band. A band which should include waves from binary neutron stars which pretty much must exists given current observations (and at a known amplitude), unlike LIGO which can only detect much more exotic and theoretical objects and mergers. So yes I do think it's worth investing in, even given the non-detections at LIGO. QUOTE (The Messenger @ Sep 6 2005, 04:53 PM) Damn! I'll say we need LISA, yesterday, not too many years from now. Any chance of bumping LISA ahead of PLANCK? The CMB has a local contamination issue that needs to be resolved to reathenticate, if possible, the accuracy of the WMAP results. But A drag-free triangulated laser ranged probe orbiting the Sun will also provide constraints upon Pioneer-like acceleration anomalies if they effect lasar ranging. |

QUOTE (PhilCo126 @ Jan 25 2006, 07:06 AM) Thanks for those links ljk4-1  O.K. for some ESA activities but members of the Press ( even Free-lancers ) are always invited to ESA events ! Moreover let's not forget that ESA published the FREE magazine ' ESA Bulletin ' which is excellent ! ( Large high quality magazine on 96 glossy pages ) Also ESO ( ESA Southern Observatory ) publishes a FREE magazine ' The Messenger ' with 70 pages on average ... So ESA isn't doing bad after all !  Just too clarify, ESO stands for European Southern Observatory and is not related to ESA in any way, so that doesn't count. The ESA Bulletin is very good though, worth pointing out. James |

QUOTE (Steffen @ Jan 23 2006, 05:15 PM) 3. Does anybody of forum live near any of them ( Jodrell Bank, etc... ) ? QUOTE (lyford @ Jan 24 2006, 03:51 AM) I live about 5 hours from Goldstone - want to go there someday - but right now I doubt my poor Ford Escort could make it...  And I'm about 3 hours from Canberra |

QUOTE (helvick @ Jan 20 2006, 08:41 AM) Apparently that will be 50 years to the day of the Mariner 4 Flyby of Mars, that returned the first pictures of a planet from a deep space mission. Indeed. What Alan didn't say (thank goodness) is that he found that out on UMSF! (from Bruce)  Link to Post |

QUOTE (Rob Pinnegar @ Jan 20 2006, 06:43 AM) [Edit: Aw, heck... I forgot to fully capitalize NH in the thread title. That looks confusing. Can someone please fix it? Thanks in advance.] I don't think you forgot, there are lots of threads like that as the board automatically modifies all capitals after the first letter of each word to stop 'SHOUTING'. Just to start this thread going I seen to remember hearing/reading during the launch that the pluto encounter is now on: 14th July 2015 James |

QUOTE (Toma B @ Jan 20 2006, 01:39 AM) That's what I want to know for sure... So is it possible to get IMAGES from ground (or space) interferometricaly connected telescopes...I don't think about computer simulations based on the data taken through interferometer, I mean REAL IMAGES like this: [attachment=3498:attachment] That depends on what you mean by "computer simulations based on the data" as interferometers don't 'take' images any image prooduced is in some sense a simulation of the sky intensity based on the data. I don't know a lot about optical interferometry (I'm a radio astronomer) but I wouldn't expect to see much in the way of pictures from optical interferometers for a long time yet. Even with the big VLT scopes the magnitude limit is pretty poor as your dividing the light up into incredibly small angular scales, so it works best on stars (which is good in a way because stars *are* small!). It's also hard to image large scale emission (like the pretty bits in your attached image) due to the lack of short spacings between telescopes (I'm not sure if the VLT's can even use the single aperture size to help address this in iterferormetric mode) Not to mention the extremly low surface brightness of this emission. James. |

QUOTE (djellison @ Jan 19 2006, 12:56 PM) One thing I've often thought of is that we have these great anims from time to time, but they're not 'real time' What would that eclipse have looked like in REAL time? It lasted about 80 seconds end to end, so I mocked up something in 3ds Max, and uses Quicktime to add a few effects to it, and this is what it might have looked like, if seen in real time. Doug Very cool Doug, I felt like I was there! I was just thinking something like that would be nice, then lo and behold along you come. James |

QUOTE (Rakhir @ Jan 19 2006, 09:08 AM) It's casting a shadow on a couple of cells. Anyway, the effect should not be significant for the moment given the total surface of the panels. Perhaps it could become in the future during the next power shortage phase ? If power gets THAT critical we won't be driving so the arm could be unstowed. Perhaps it could be angled to reflect a bit *more* sunlight onto the panels? |

QUOTE (edstrick @ Jan 16 2006, 09:51 PM) I stitched the latest 6 color images of the hill to the west of Spirit (Jan 15 folder on the exploratorium). The left frame is only bands 5 and 7, saturation stretched for rough compatibility. And my version of this one, still missing a bit from the leftmost L2 frame.
