 MESSENGER: MErcury Surface, Space ENvironment, GEochemistry, and Ranging
MESSENGER uses gravity assists from Earth, Venus and Mercury to lower its speed relative to Mercury at orbit insertion.
The plane of the orbit is inclined 80° to Mercury's equator, and the low point in the orbit is reached at a latitude of 60° north.
Because the sunshade must protect the main part of the spacecraft from direct sunlight during propulsive maneuvers, the timing of these maneuvers is limited to a few days when Mercury is near the same point in its orbit as it was at Mercury orbit insertion.

 MESSENGER's First Mercury Flyby Reveals a "Whole New Planet" - Planetary News | The Planetary Society
Prior to the January 14 MESSENGER encounter, the most recent visitor to Mercury was Mariner 10, which swung by Mercury three times in 1974 and 1975, producing images of only 45 percent of the surface.
MESSENGER saw nearly all of Caloris, including all of the previously unseen part, and the first thing that the MESSENGER team learned, Strom said, is that it's even bigger than originally thought: 1,550 kilometers (960 miles) in diameter instead of the 1,300 kilometers (810 miles) estimated from the Mariner 10 view.
MESSENGER's ultraviolet and visible spectrometer, part of the MASCS instrument, mapped the tail of Mercury as the spacecraft approached for its first flyby of the planet.

 Anthony's Lifting Messenger
The mintie messenger and all the other messenger plans I have seen used basically square framed sails and as such were basically reasonably heavy framed, relying on the wind to `drag' it up the kiteline.
The goal is to build a `lifting messenger'' and that is achieved though the sails of the messenger.
In my experimental messengers before this, with the hook so close to the lower end of the messenger, the load weight and sail lift caused the front of the messager to lift the front load support from the kite line.

 Commons Messenger - Overview
Messenger implements session pooling (which can be quite hard to do with JMS) which makes JMS very easy to work with.
Messenger also provides a Messagelet Engine which is a JMS based container that can be deployed in any Servlet Engine to process JMS messages via MessageListeners, Message Driven Objects, Servlets or JSP.
Also notice that the Messenger API is a simple facade, no need for Topic and Queue specific coding as well as the use of MessageConsumer, MessageProducer, TopicPublisher, TopicSubscriber, QueueSender, QueueReceiver and the plethora of Connection and Session objects.
