Re: [Utah-astronomy] Last night's lecture

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".

OK, it looks like Feb. 4th will work for all who replied, so lets go with that. 1:00 PM start will allow us to avoid the bulk of the crowd, although it does tend to lessen the pie selection. See you all at the Left Fork on Saturday! Maybe the Ground Hog will not have seen his shadow thanks to the fog!

Ominous Anniversary
by Dale Hooper 27 Jan '17

27 Jan '17

Well, today is a rather ominous anniversary as we enter what has become known as space disaster week. This is the 50th anniversary of the Apollo 1 fire which took the lives of Gus Grissom, Roger Chaffee and Ed White. Of course tomorrow is the 31st anniversary of the Challenger disaster and Wednesday, February 1st is the 14th anniversary of the Columbia breakup on re-entry which many of us OAS and SLAS members witnessed. Clear skies, Dale.

Time to gather for lunch and get caught-up with what everyone has been doing during this particularly snowy winter. Which weekend looks best for everyone, February 4th or the 11th?

Huh. Interesting concept. It's apparently a dedicated scope, it seems. I wonder why they don't have any pictures of the scope itself? If anyone gets to see it, let us know--and find out if they have a price! John

Re: [Utah-astronomy] Unistellar Optics demo

There is a March 2016 article in S&T about video observing using the Mallincam video/camera/eyepiece or the like. It projects a layered image to a computer or TV screen in real time, constantly updating so that you are able to see colors of nebulae and fainter objects. Is this Unistellar Optics product the same thing? I am still thinking about what telescope to buy, and whether video observing might be the amateur observing of the future. If so, I need a telescope that will allow me to track well enough to have this gadget work.However, the pictures in the March S&T are not as good as a well-made photo, so I don't know about the trade-off with direct observing. Has anybody on this list tried video observing, and with what? and how satisfying was it? best regards, Marlene Egger
