Re: [Utah-astronomy] Last night's lecture
by Joe Bauman 11 Dec '18

11 Dec '18

Brent, speaking of the ISS, I have wondered if it could be put into an orbit that continuously cruised between Earth and Mars. When it swung by Mars it could drop off and retrieved crews. I don't see how the radiation would be any worse than the ISS crews are already exposed to. ------------------------------ On Wed, Feb 25, 2015 8:18 AM MST Brent Watson via Utah-Astronomy wrote: >I attended the lecture last night on trajectories. It was really a good, stimulating talk. Thanks for passing the word along. >There were some interesting side comments made about our launch capabilities and the Mars One effort. Mr. Adamo was not at all enthusiastic about the Mars One effort. His opinion is that the effort is doomed because there is not really a way to assure that folks going there would be safe - primarily from radiation. He has done some work with a former flight surgeon on designing a spacecraft to go to Mars. Their result is that in order to get sufficient shielding (using a water jacket), the spacecraft's mass would be around 380 metric tons. That is for a small crew, probably only about 5 members. For a point of comparison, the ISS mass is 400 metric tons. He made the comment that an astronaut who made this trip could only go to space once in this craft, and then he would be at the limit of radiation exposure for his life. The NASA limit is an increased risk of developing cancer of 5%. >That brings us to our current launch capability. Our latest heavy lift rocket - the one we are currently developing - will have the capability to lift 130 metric tons to a very low earth orbit. So low, in fact, that it would burn up at perigee. The Apollo 17 Saturn 5 rocket lifted 140 metric tons into earth orbit -- higher than the new rocket will go. (I am sorry, but my mind will not allow me to recall the name of our currently being designed rocket.) Recall that it took several dozen shuttle launches to assemble the ISS. The Mars One vehicle would require either a hugely more massive launch rocket or a similar effort to build the craft. >As I mentioned, it was a very intellectually stimulating lecture and did involve several ordinary differential equations. They were nicely explained in English by Mr. Adamo. This was the first time I have seen some real math put to Kepler's laws. There were many charts showing what it takes to leave the earth and go to the moon or Mars. It was a very well done lecture. >The above is my recollection of the lecture, and may not actually represent the opinions of Mr. Adamo. It is only my interpretation of what he said. He knows his stuff, that is apparent. Thanks Patrick and Dr. Sohl for passing the word along. >_______________________________________________ >Utah-Astronomy mailing list >http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy > >Send messages to the list to >Utah-Astronomy(a)mailman.xmission.com > >The Utah-Astronomy mailing list is not affiliated with any astronomy club. > >To unsubscribe go to: >http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy >Then enter your email address in the space provided and click on "Unsubscribe or edit options".

Liver & Onions reminder
by Chuck Hards 31 Mar '17

31 Mar '17

Just a note to remind you that we will be at the Left Fork Grill tomorrow for a meeting of the L&O Subcommittee. Some of us are bringing meteorites but the topic of discussion will be Anything Goes, as usual. Left Fork Grill 68 W 3900 S, Salt Lake City Time: 1:00 PM Plenty of on-site parking, and there is a TRAX station just a block west of the restaurant. If you haven't yet RSVP'd, let me know if you are coming, and how many in your party, before 5 PM tonight, so I can reserve our table. This looks to be a well-attended session. Also, I'm selling quite a few older model telescopes so if anyone is looking for something "Classic", we can talk about your needs then as well. Hope to see you there!

EpiPen
by Grammy Terry 23 Mar '17

23 Mar '17

Hey Chuck, What an ordeal you've had. So good to hear you're on the mend. We'd appreciate if you'd share anything you've learned about how to save money for the EpiPen. We have a 3 year old granddaughter with severe food allergies. Wherever she goes, an EpiPen is close by. I'm amazed you only paid $10 for two. I find it ridiculous that our daughter's young family has to pay so much out of pocket for this life-saving serum. It's not covered by their insurance yet. Parents nationwide are pushing for that to change. Our granddaughter has had to have it administered twice because foods that had previously been safe suddenly caused a severe reaction. The serum allowed time for an ambulance to arrive and hurriedly whisk her off to the ER. Watching her little one swell up, rashes spread and have increasing difficulty breathing is one of my daughters worst moments ever. Thank you, Kathy

Hey Chuck, We had a lovely visit with Larry Holmes after the ground breaking at SPOC. He invited Mike and me to the infamous L&O and made a quick quip that we don't have to order it. :). Please add two more names to the list. Though we know a few that'll be there, it'll be good to finally put names and faces together. This will be our first time, would you mind giving the address and what time we need to arrive? Thanks much, Kathy (and Mike) Terry

Micro-meteorites in today's NYT
by BOB MARILYN 22 Mar '17

22 Mar '17

I’m intrigued by today’s article in the New York Times science section about amateur micro-meteorite collection. If they can find such beautiful objects in gutters and on roofs, I would imagine that the salt flats should have collected a lot of objects smaller than bowling balls. Has anyone of this list successfully searched and collected any there? Any tips to share? Bob Grant Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10
