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.

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".

I have been a space and astronomy fanatic since my childhood days. My parents are both astrologers hence the stars, the moons and the planets have been an integral part of my upbringing. I recently moved to Salt Lake Valley from Florida and I used to live in Kenya before that. I owned a telescope in Florida and did lots of sky gazing. It was and still is my favorite hobby. One of my co-workers is also a big fan and used to be a SLAS member in her childhood days, she recently suggested me and introduced me to your pristine community. Last week I borrowed a telescope of a member from my ward and I would love to share this great joy with you all. I would also love to be a member. Only concern is I live in Draper and it would be hard to commute to the observatory. Although it is not an issue, I was just throwing it out there to see if I could car-pool with someone. Anyways, please let me know more details about the community and how I could be a part of it. I would love to come visit the observatory and attend one of the community meetings before I sign up. Your feedback is valuable to me, Best Regards Sent from my iPhone
