2000.11.2 Mars Seminar comments by faculty

I kept notes of who asked what during my Mars seminar.  I saw PAM Abusali, a famous researcher at the Center for Space Research out on Balcones Road – I took his orbital dynamics class, and we got along well – and he wondered why I was still on campus. He thought that was my dissertation defense.  Dr. Hull was there, the nonlinear optimization expert, but he did not ask any questions. I had solved the Mars problem without his monster algorithm.  He did not even ask how I did it.

<u>Presentation Comments</u>          11-2-00

Abusali – distance of semi-minor axis from $f = 90$? – $f = 90$ exactly? (asked 3x)

Fowler – why @ $f = 90$? – why would tangential thrust @ $f = 90^\circ$ elongate orbit? – “free-return” is at Sun – aren’t going to Earth?

Ocampo – how get IC for s/c ~ position; what abt. velocity? – how can you compare this to a real NASA JPL mission?

Hull – never said a word, smiled, or <u>anything</u>


grad student – isn’t this a bi-elliptic transfer
