SpaceX CRS-3 Launch delayed

Disappointing!

As many would know, this launch will include the testing of firing of the booster's engines as retrorockets to return the launcher to earth in a controlled manner. Landing gear will also be deployed before the booster ditches into the ocean. This test will be a major step towards having boosters return to earth and landing gently for quick turnaround for relaunch.

With one of the major costs associated with rocket launches being the retrieval and overhauling of the boosters, having the boosters land by themselves (non violently) will probably lead to huge reductions to launch costs.
