28 Jul 20 - 09:49 PM (#4066357) Subject: BS: Perseverance Launch - Roll On Mars! From: robomatic Tomorrow (30 July 2020) morning 0730 Eastern Time the Perseverance mission is supposed to blast off. This is the latest of the American exploration vehicles and one of three recent launches to explore Mars. NASA's web site discussing the launch is here . The International Business Times has an interesting article here. The launch date has changed several times this month so if you actually want to see this online, you have to keep yourself informed. 0730AM Eastern Time US = 0330AM Alaska Time = 1230 PM Greenwich, or as we like to say, Zulu time. This Mars Rover is far more massive than the previous successful units landed on the Red Planet. It is supposed to collect recoverable samples of physical material. |

29 Jul 20 - 03:45 AM (#4066376) Subject: RE: BS: Perseverance Launch - Roll On Mars! From: robomatic The NASA fact sheet on Ingenuity the copter says "solar powered and able to recharge". Meanwhile, in the OP I was in error. The latest blastoff information is for 30 July which is Thursday. And I believe the time is 0750 Eastern Time US which means 0350 in Alaska and 1250 PM in Greenwich UK. |

From: Donuel Cool When they launch automated fuel factories to be placed on Mars for return space ships will be interesting for a couple reasons. 1, they are serious in the long run or 2 If they don't, it may indicate propulsion is in a new age and we haven't been told. |

30 Jul 20 - 07:33 AM (#4066537) Subject: RE: BS: Perseverance Launch - Roll On Mars! From: Donuel After launch in an hour it will take only 7 months to get to Mars. Contrary to the title there is no proof there is a roll on Mars. Nor are there pastries, donuts, brioche or cookies. |

30 Jul 20 - 08:05 AM (#4066540) Subject: RE: BS: Perseverance Launch - Roll On Mars! From: robomatic The explainers are saying how due to the relative orbits between Earth and Mars we had a launch 'window' First burn gets us into a park orbit. That allows the package to orient itself and prepare for a second burn which will enable the device to leave orbit and head not so much for Mars as to where Mars will be. Arrival expected for February 2021. Second burn to start in under half an hour. |

30 Jul 20 - 08:39 AM (#4066550) Subject: RE: BS: Perseverance Launch - Roll On Mars! From: robomatic Second burn underway. Takes about six minutes. |

30 Jul 20 - 09:00 AM (#4066551) Subject: RE: BS: Perseverance Launch - Roll On Mars! From: robomatic Second burn is complete. Separation of the payload is complete. The Perseverance Mission is on the way to Mars. Destination Jezero Crater on or about 18 February 2021. What makes this mission different from earlier rover missions: Much larger and more sophisticated rover, powered by a nuclear battery. First powered aerial extraplanetary explorer "Ingenuity" powered by solar. New exploratory location. Collection of samples for analysis to be brought back to Earth labs. There is a concentration on evidence of life having been or still being on Mars. Just hope we can avoid running into Musk's roaming Tesla on the way! |

30 Jul 20 - 09:21 AM (#4066555) Subject: RE: BS: Perseverance Launch - Roll On Mars! From: Mrrzy I read two things about this: One, the samples cant be analyzed in situ, but are to be brought back by a later mission. How on Earth, um, how in the world, um, how is said later mission going to take off? Two, this phrasing from a Guardian article on the search for "lyfe" always bugs me: All living organisms on Earth take in energy, use and change it, and then release it in a less useful form as waste. Less useful to that organism, perfectly useful to another for whom it is substinence, not waste. Nature doesn't waste shit, literally or metaphorically. If we stopped referring to things *we* don't want as waste, it wouldn't be wasted. This is how reusing, repurposing, and recycling work. And I don't know how I feel about the word Lyfe for It's life, Jim, but not as we know it, not as we know it, not as we know it. And now it's a music thread. |

I 'member that old song aired on Doctor Demento. The channel that showed the Perseverance launch on Space.com went on to interview astronauts on the International Space Station, two Americans are headed for an old fashioned capsule splash down in the sea over the weekend. One of them was going on about recycling the very water they drink, and the interview seemed to me to abruptly end at that point! |

From: Donuel It's been an hour, to my untrained eye, of trying to open the hatch that looks welded shut from reentry. The official explanation is that they are venting fumes. It looks like they have tried a dozen different tools... It opened... |
