Yesterday my wife and I drove about 40 miles to a dark spot in Georgia, USA, and we had good naked eye and optical views. I could not get a photo due to being bitten alive by bugs. Tonight I viewed the comet from my house ( light pollution nightmare ), and I got a pretty good view and snapped a picture on my cell phone via my 20x60 Bushnell Spotting scope. The comet quickly dimmed as it descended into the light and industrial pollution of Orange Park, FL. Also at the time there was lighting from a thunderstorm about 80 miles away.  |

Photographed with a cell phone through a 20x60mm spotting scope from Orange Park FL today. It was not visible to the naked eye.  |

QUOTE (Steve G @ Jul 13 2020, 12:33 PM)  Parker probe has been busy spying on comet NEOWISE. I still haven't seen it myself. https://www.nasa.gov/feature/goddard/2020/n...-comet-neowise/ I've spent the last 3 days unsuccessful too. Evening viewing starts for me tomorrow here in Florida. |

QUOTE (Julius @ Jun 15 2020, 04:08 AM) I have been reading up ahead of the launch and hopefully safe landing of Perseverance rover on Mars. I am surprised at the energy constraints the Curiosity rover had to work with given that 110 W are used to generate electricity for rover operations on the surface but a part of it also is' wasted' in keeping the rover parts warm. Has anything changed with the new Perseverance rover regarding energy usage ?? The energy is not really wasted, the motors and joints have to be warmed up to work correctly on Mars, as it gets extremely cold there at night, as there is virtually no atmosphere to regulate the night time temperatures. |

QUOTE (neo56 @ Apr 21 2020, 03:26 PM) When looking at pictures of the surface of Ryugu, I always feel hard to estimate the scale: are these rocks or pebbles? How big are these rocks ? Obviously, scalebar helps but I find more helpful to add objects of everyday life to the pictures or people to give the scale. I really like when Earth objects are added to help with the scale. |

QUOTE (Explorer1 @ Apr 9 2020, 07:55 PM) Some very impressive images came down showing Earth's rotation as it approaches, as seen on social media. The MTM external cameras were a good idea! I watched the ESA flyby simulation live. |

I took this with my 60mm spotting scope and 45X zoom.

QUOTE (atomoid @ Oct 29 2019, 07:55 PM) how much better science can be accomplished at full depth vs the 'acceptable' 3 meters? The design min is 3m and the only difference I can recall from the briefings was at 3m it would take quite a bit more time to achieve the results. |

QUOTE (Explorer1 @ Oct 14 2019, 11:05 PM) Yes, great to see movement in the right direction. What will happened when the mole gets too low in the ground for the scoop to press against it anymore? Hopefully that will be enough for it to get traction and finish digging on its own? That is the proverbial 64 million dollar question. My guess is the mole will be fine and dig deep  . |

QUOTE (Steve G @ Sep 21 2019, 01:17 AM) I just wonder how far will they go before they give up. If all appears lost, will they try things as radical as that? Or backfilling the hole, pack it down, and even put the skoop on top of the probe itself to force it down? Like, how far would they take this, and what would be the minimum depth to get any usable science? The worse case minimum depth is 3m. At that depth it will take a lot longer to complete the experiment. |

QUOTE (tanjent @ Aug 6 2019, 03:50 AM) I think the main reason they are not trying to scrape up soil and fill it in is that they have no suitable tool with which to do that. Yes they do, they have a scoop, with a sharp edge for leveling the ground for SEIS, but they did not need it for SEIS as the ground was flat enough. |

QUOTE (Phil Stooke @ Aug 1 2019, 11:13 PM) They are, quite rightly, very cautious. All the pre-positioning and now this first touch may only be to ensure their spatial model is correct before trying the real process. Phil The update they did said they were pretty short on time and wanted to (forgive the pun) press ahead and try something before conjunction. |

New pics show the ground hardly moved, probably packed solid. |

QUOTE (Hungry4info @ Jun 28 2019, 01:53 AM) It will be landing near the equator and heading to Selk crater. It will therefore likely be much too far from any liquid bodies of ethane to worry about that. Good point, it's landing in sand dunes. |

QUOTE (pioneer @ Jun 27 2019, 10:31 PM) Interesting mission. I wonder how it will avoid landing in a lake of liquid ethane or sinking in anything resembling quicksand. It does a recon before landing. |

Hopefully they can pack the soil down with the scoop and re-start hammering. |

QUOTE (PaulH51 @ Jun 24 2019, 01:08 AM) It was planned, albeit 1 day later than planned. They also planned further lifts to carefully raise the housing off the probe. The mole appears to be tilted, roughly from east to west with what maybe a void around the probe. It also looks to a be little further in the ground than they expected. There is a few days before the next lift details The mole must have unluckily hit a rock right as it was going down.  . |
