Re: [Utah-astronomy] Last night's lecture
by Joe Bauman 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".

Any interest in an astro yard-sale?
by Chuck Hards 07 Sep '17

07 Sep '17

I have way too much astro stuff, from ATM bits to collectible telescopes, accessories, etc. I was wondering if, I held an astro yard-sale sometime this fall, would there be enough interest from others to warrant pulling it all out into the driveway for a day? I need to downsize, retirement is only a few years away. If there is sufficient interest, I'll gladly hold the yard sale. I would give everyone at least two or three weeks notice.

I'd be interested in looking, and especially if it was a multiple-yard sale.

Eclipse Photo from Casper
by Tom Uhland 25 Aug '17

25 Aug '17

All, Just a lucky shot from the parking lot of the Holiday Inn Express in Casper. The staff was extremely hospitable, brought chairs out for one and all and had Eclipse Shades for everybody. Traffic between South Weber and Casper was very good both directions. https://www.flickr.com/photos/108505564@N02/ Nikon D-7000, TAMRON 18-280 mm, ISO 400, 1/30 sec, f/22 per Fred Espenak's very informative site. Never posted a photo before, but would like to thank everyone who does for all the great photos and wonderful information provided. Tom Uhland South Weber

Great shot! Love seeing the trusty D7000 doing its thing so well still, I let my daughter use my D7000 with a 70-300mm and she got a great shot of the diamond ring as well. Thanks for sharing.
