19th February

Running Out of Time

The article expresses concern over the recent deal between Pakistan and Tanzim Nafeez Shariat-e-Muhammadi (TNSM) and its implications in future with a possibility of Taliban takeover of Pakistan and access to nuclear warfare which can be direct danger to US and India.
Entire world has condemned this deal and it seems that the Pakistani premier, Zardari, speaks as a powerless head desperate to push US for military action. Some say it as a tactical move by Pakistan to open a front in Waziristan against TTP. But more troubling is the perception of some general in Pakistan military that Taliban is an asset worth conserving even at the cost of integrity of Pakistan state. Presently Taliban controls the entire area from east Kabul to West Pakistan. However, the game changer would be acquisition of nuclear warfare by Taliban which would be direct threat to India as well as US.
The takeover is similar to the Afghan takeover of Taliban in 1994 and to expect Pakistan military to regain the lost ground would be a grave mistake. Presently the fallout of Pakistan seems to be worst with govt hardly controlling the military and the jihadi elements in close proximity with the generals and ISI.

Space Litter

The article talks about the increasing space litter that is increasing the chances of space collisions in future with the first incident just reported. The author insists on more data sharing and coordination between the space agencies across the world to tackle the issue.
The recent collision between the American communications satellite and Russian satellite in North Siberia has raised concerns of increasing space traffic and a need of a system to control it. The greatest threat is to the International Space Center which can get damaged even by one of the more then hundred pieces of debris the collision has created. Out of more then 300k objects of more then 1cm in diameter are orbiting around the earth but US is only able to monitor around 18k of them. Thus, there is a strong need of combined effort from the space agencies across the world to share the data and coordinate among them to set up Space Traffic Control system on the lines of Air Traffic Control system. 
But this is also a part of the answer since it is said that even if no objects are launched till 2055, amount of debris produced from collisions of dead satellites would overtake the rate of debris removed from space by natural means. So, some agencies are thinking to develop a robotic system to remove debris from space. However, currently, the best way to prevent the damage for govt and commercial satellite operators is to share data among each other.
