S283: TMA-4

The last TMA. I need a big score to up my OCAS average on this one. Alas not to be, despite spending far too long on it, repeatedly reworking it. I'm just not putting what is in the marking template apparently.

Question 1 is about evidence for water flow on Mars. You have to download a paper discussing recent evidence for water flow on Mars and compare the paper with details in the book.

Question 2 concerns rainfall on Titan, and the atmospheric structure there.

Question 3 concerns the Drake equation, and asks you to calculate civilisations based on some given numbers.

Question 4 is about extra solar planet detection using the Doppler method. It also includes details about transit detection, what its probably density is in comparison to Jupiter, and so what sort of planet it is. Also how it might have got there through migration.

Question 5 is all about suitability for life based on IR and light spectrum. Discussing possible spectra and what they might tell you, and what you would hope to see in some cases. Also reasons the planet might be habitable but still nto show up on the spectrum results.

Last TMA, not the mark I was hoping for, and in general the marks for this course have been hard to get compared to all the other courses I have done with the OU. I still got reasonable scores, but found it very difficult to get a good score on a TMA, as it seems very picky about minutia of detail. If you answer is right, but not what is wanted, you score less than otherwise.

Anyway - now just the exam.
