Ok, I got a 3.977x10^9 for T2, so my figures must match yours up to that point. Things start to go wrong for me with the equation for M2. What was the figure you got for M2 since you corrected your calcuation for T2? I get about 3.565x10^10 for M2. I'm not sure if my order of operations is...

From what I got, M2 - M = 3.4309812736×10^34 kg This times G comes to 2.288x10^24. For force (F), I multiply this by the mass of my iceteroid (which I worked out separately as 3.924x10^10 kg), and this total quantity by the square of 40 AU in m, giving me about 2.508× 10^9. For acc (same as F...

Thanks Tommy and Martins. I am reviewing over the figures. Math is not my strong suit, so I apologize in advance for what may be really naive questions. For the equation that Martins first showed, I take it the M for GM = "mu" is the Sun's mass, right? That would be 1.988435×10^30 kilograms...

Thanks again for the reply. If it is only 10,000 m/s per year, that would be acceptable. As implied in my original post, I am willing to burn off about 10% of the iceteroid's mass (for a mass ratio of 1.111) which should allow for a delta v budget of >30,000 m/s. In that case, 10% mass burn off...

Thank you everyone for the warm welcome. I look forward to future discussions with all of you.

Thanks Tommy for your explanation. For now at least, I am not going to do the math on the smaller shuttle-like vehicles. I think I will leave it to the reader to assume that their mass ratios are sufficient to get the job done. However, the iceteroid craft is much more central to my story, some...

Hello all Though I've downloaded and used Orbiter in the past, I only just now registered with this forum. I was drawn to Orbiter because of my interest in space opera of the hard sci-fi variety. Currently, I am attempting to write my own hard sci-fi fiction and am hoping to share ideas with...

Hello all. I'm new to this forum. I've downloaded and used Orbiter in the past, but only now registered to this forum, my reason for registering having less to do with Orbiter and more to do with my interest in orbital mechanics. Currently, I'm in the first stages writing some hard sf, and I...
