It seems that Apophis will still hit the Earth in 2036 (by 49 million Km, pufff!). But there is another medium size kid in the block. Not a planet killer but big enough: asteroid 2011 AG5. Bad Astronomy has a good article in evaluating the options for start planning a mission to potentially change the orbit of the asteroid.
Before scaring anyone it is god to remember that NASA estimates very low the probability of an impact in a recently update: Asteroid 2011 AG5 - A Reality Check. Ranked "1" in the Torino Scale...
With something with so low probability to happen (crash into Earth) and only one agency from one country maybe considering it (NASA/US) I cannot see the people deciding where to expend the budget to invest some money on a close up mission and a potentially deflecting one.
But it would be nice just for 2 other things even if it is downgrade to Torino level "0":
- the scientific value of a mission like this
- it will be cool to follow the news of a mission to deflect an asteroid, even just for practice!
