Requirement
Total mass of CanSat, container, and all descent control
devices shall be 700 grams. Mass shall not vary more than +/10 grams.
The cansat must be installed in a container to protect it from
deployment out of the rocket.
The container shall fit inside the cylindrical payload section of
the rocket defined by the cylindrical payload envelope of 130
mm x 250 mm length control system including the descent
The container must use a descent control system. It cannot
free fall.
The container shall not have any sharp edges that could cause
it to get stuck in the rocket payload section.
The container must be a florescent color, pink or orange.

CanSat Budget – Hardware
• Provide a table listing the costs of the CanSat flight
hardware
• Table should include
– Cost of major components and hardware
– Indication of whether these costs are actual, estimates,
or budgeted values
– Indication of hardware re-use from previous years
• The current market value for re-used components should be
included

Travel
– Income
• Sources of project income

The goal(s) of this budget are
– To provide an understanding of the overall design and development costs
– Get the teams thinking about the overall costs including necessary funds for
travel
– Identify shortfalls in the budget that require attention
• In the past some teams have not been able to attend the competition due to a
lack of funds
• If caught early enough, there are a number of resources for funding that may
available to teams
– THE COMPEITION DOES NOT PROVIDE ANY DEVELOPMENT FUNDING OR
DONORS

Program Schedule
Overview of development schedule to include
– Competition milestones
– Academic milestones and holidays
– Major development activities
– Component/hardware deliveries
– Major integration and test activities and milestones
The schedule should be “wrapped up” to 1-2 levels
– Show high-level tasks only in order to make the schedule readable
– It is recommended a schedule at lower levels is developed in order to provide the
team with tools for tracking progress and assessing trouble areas
The goals of this schedule are to
– Provide a tool for the team to track progress of CanSat design and development
– Provide tool for judges to assess trouble areas and offer ways for the team to best
meet the objectives of the competition
A Gantt chart on one slide showing task start and stop dates and durations is
recommended
– Schedule should include linkages between tasks to provide the team with an idea of
what happens in the overall flow when milestones are not met on time
Make sure the schedule is readable in the presentation
– This may require the schedule to be broken between multiple slides
• Failure to do so will result in a loss of points

Shipping and Transportation
• Discuss plans for shipping/transporting the CanSat
hardware to the launch site
• In past competitions, CanSat hardware checked with
airlines was lost
– Consider options for shipping hardware to the launch site
(typical for a satellite and ground system program)
– Consider carry-on restrictions
• Consider shipping/transportation of tools and
equipment
– Antenna mast and assembly
