A recently discovered asteroid, named 2007 WD5, could hit Mars on January 30, 2008 at around 10:55 UT. There is a small probability of collision with the red planet, about 1 in 75.
The asteroid passed close to the Earth on November 1, before it was discovered on November 20, 2007. The 2007 WD5 is estimated to be about 50 meters across.
If the collision occurs, the asteroid would hit Mars with a velocity of about 13.5 km/s ( 48,000 km/h approximately ), and releases an energy of about 3 MT of TNT.

Google goes green
Google is committed to use clean energy, in the near future for its vast infrastructure of computers. To date, these computers consume a large amount of electricity, and most of this energy generation produce greenhouse gas emissions.
Google has decided to take an active policy to address the climate change, becoming a carbon neutral by the end of 2007.
To do this, Google already has taken several steps, working on plans for efficiency and energy saving, investing in renewable energy, such as solar panels installed at Googleplex, the complex in Mountain View, California, promoting the use of products and services based on internet, etc..
The solar panels installed on Googleplex has a capacity of 1.6 MW, approximately one third of the energy peak that the complex consumes, and Google has set a target for the year 2012, to create a new generation capacity 50 MW in renewables for their data centers.
Another commitment for the year 2010 is to reduce by 50% the energy consumed by computers used in data centers, as part of "The Climate Savers Computing Initiative."
Google has also launched "The RechargeIT Initiative" to encourage the reduction of greenhouse gas emissions and reduce dependence on fossil fuels, accelerating the adoption of the technology of hybrid electric vehicles.

The First Post
Hi all ! ! !,
this is my first post at The Jim's Place blog, so it will be short.
For a moment I thought to title this post Hello World, but all people use the same expresion in situations like this, so I prefer to call it "The First Post".
