Discuss the below:
Q: (i) Based on the characteristics of its orbit, what type of Solar System object is 2008 TC3? Explain how you have arrived at your answer.
(ii) Measurements of 2008 TC3â??s orbit in October 2008 led to an initial estimate that it had a 0.3% probability of impacting the Earth in 10 yearsâ?? time. By January 2009, improved measurements had led to an increase in the estimated probability of impact to 8%. Further observations in March 2009 led to a revised probability of 0.7%.
Which you should as part of your assignment, show how the Torino Scale number of 2008 TC3 has changed as measurements of its orbit improved (label each point). Note that Figure 3 has a log scale.
(iii) Recent mathematical modelling has shown that as the orbit determination improves, the calculated collision probability can temporarily go down (but not to zero) as well as up, for an asteroid that will eventually impact the Earth.
Observations made in June 2009 now confirm a definite impact (i.e. it is certain to occur with 100 % probability; in this eventuality the probability of impact cannot now decrease). How would you recommend that scientists and decision makers communicate the risk and uncertainty to the public at each of the four time points (Oct. 2008, Jan. 2009, Mar. 2009 and June 2009) when the impact assessments were made?
(iv) It is decided to launch a spacecraft to mitigate the threat from 2008 TC3. These options are given on Table 2. Give possible disadvantages for each option by completing this Table and submitting it as part of your assignment. You may find that some disadvantages are appropriate to several mitigation techniques, but do try to give unique answers as far as possibl
