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".

Fw: June 21 meeting
by Joe Bauman 29 May '17

29 May '17

I am planning a session about the eclipse at the SLAS June 21 meeting. I'm filling in for Dave Bernson because he and others will be at the Bryce astronomy fest that day. My plan is to find some solar eclipse experts who can speak to us, other than club members. Please drop me an email (at josephmbauman(a)yahoo.com) with suggestions on whom to invite. Meanwhile, I'll be checking colleges and universities for speakers. John Hollenhorst of KSL TV asked Patrick Wiggins and me to be there an hour early to talk about total eclipses we've witnessed (five apiece) and he would like others who have seen them to show up early to talk about their experiences. All are welcome, whether members of the club or not. In addition, I think John's cameraman will film part of the meeting. I want to send out notices to the public for this fun event once I line up speakers. Check this site for details on the meeting place and time: http:slas.us Thanks, Joe

Rocket exhaust cloud?
by Ian Glenn 28 May '17

28 May '17

Currently camping near the Wedge Overlook on the north Edge of the San Rafael Swell, moon has set, almost cloud free perfect sky! But there is quite a curious cloud due north. Takes up about 3 by 5 degrees of sky perhaps, has some linear extensions. The town of Castle Dale could be emitting and illuminating this cloud but it has the very faint and tenuous nature of a mesosphere cloud or rocket exhaust cloud. I'm afraid I can't get a picture. Any one else seeing this? Incredibly beautiful. Happy new moon everyone, Ian

It certainly could be an auroral display. I've seen several pretty impressive ones from Utah locations over the years.

Hi, I was up on top of the mountain at Cedar Breaks and we were watching it. We think it was the aurora. There was a photographer there and he was getting color out of his shots of it. He is going to send out his photos. There was a solar storm. Could it be???????
