DARE is the main rocket supplier for the yearly Dutch CanSat competition since its start in 2007. This competition is organized by the TU Delft as an outreach to Dutch secondary schools. Teams of 15-16 year old pupils compete to build the best CanSat. A CanSat is a small satellite built in a soda can, a perfect tool to learn pupils about space technology and gain their interest to pursue a study in technology. Since the beginning DARE has been improving its CanSat Launcher to better suit the growing competition needs. Experience in the logistics and operations of the launch campaigns has resulted in very successful launches of more than 30 CanSat’s up till now. Learning from past experiences DARE has grown to be a professional and reliable partner in the organization of this competition. The CanSat Laucher can carry several CanSat’s at once to an altitude of one kilometer in about 15 seconds. At its highest point the rocket releases the CanSat’s. Gliding down on their own parachute they will perform their specific missions. In the meantime the launcher will eject its own parachute, gliding gently down to be reused. A modular design has enabled the final assembly of the launcher to its motor section just before launch. Furthermore all ejection and release mechanisms are mechanically operated. This makes the launchers safe in operation and accessible for the pupils to insert their own CanSat’s, enhancing the experience. Currently the CanSat Launcher has reached its sixth version, CanSatLauncher v6.

The latest addition to the CanSat launcher family and a new step forward. It was first developed in 2009 as a prototype and is able to carry upto 6 CanSat's to an apogee of 1 kilometer. A major difference with its predecessors are the dimensions. The diameter was doubled to 200mm, it measures almost 4 meters now and when it is ready to go it will weigh 25kg. Still it leaves the 6 meter launch rail with almost 80km/hr, reaching it's apogee almost 12 seconds later.

The bottom module of the CSL v6 is reserved for the propulsion system. In this version the Booster solid rocket motor, designed and flown on Stratos I, can deliver a total impulse of 4000Ns. The fins are also attached to this module, ensuring a straight and stable flight. The bottom module will be detached from the rest of the rocket when it is preparred to be launched with CanSat's.

This ensures the rocket is safe to operate when prepared for launch. Only just before inserting a fully prepared rocket in the launchtower is the module attached again. This procedure is performed by a small crew of DARE specialists.

For a CanSat Launcher the most important module is off course the payload module. The CSL v6 has two bay's which can both carry three CanSat's, these are released by use of rotating doors. These doors are operated by servo's, and controlled by the Main controller unit, built in the nose of the rocket. Here the brains of the rocket reside controlling every aspect of the flight. In between is the recovery module. This module contains the parachute to recover the entire rocket. The parachute is ejected after the CanSat's are released by ejecting the hatches. Two hatches are used so the procedure is redundant, ensuring a high probability of a succesfull recovery.

One of the three rockets flying on the 2010 CanSat Campaign will have two camera's onboard to record the entire flight. One is mounted in the motormodule, looking outward next to the motor. The other is located in one of the CanSat bays hoping to catch the CanSat ejection on record.

Between 2005 and 2006 DARE started the development of its own CanSat Launcher. This resulted in three prototypes: CSL v1, CSL v2 & CSL v3. After the succesfull launch of the third prototype development started on the first production model, the CSL v4, for the pilot CanSat Competition held in 2007. A year later the competition went national and needed an improved model, the CSL v5. This rocket incorporates all the experience and lessons learned during the previous versions. As a result the rocekt is very reliable and easy to use, in short DARE's workhorse for a couple of years.
