This dataset provides information on budget appropriations for each fiscal year starting in FY 2010. The data provides granular detail down to the budget organizational unit and and object class for the department request, the Governor's recommendation, the enacted budget, and the adopted budget. The state fiscal year runs from July 1 to the following June 30 and is numbered for the calendar year in which it ends. The State of Iowa operates on a modified accrual basis which provides that encumbrances on June 30 must be paid within 60 days after year end. The Legislature may enact exceptions to this statute and usually do so for capital items which may run for several years. Department names and budget units for FY 2010 - 2015 are based on names used in FY 2016.

The objective of the proposed research is to identify stable configurations of a rigid deployable aerodynamic decelerator for Mars atmospheric entry which provide increased landed mass capabilities for planetary exploration. Rigid deployable aerodynamic decelerators are a proposed means of augmenting the drag performance of atmospheric entry vehicles without adding significant mass to the system. The development of such a technology would allow for bridging of the gap between the robotic missions which we have successfully landed on Mars to date and the potential human class missions. This objective will be accomplished by performing a systems level architecture assessment to identify potential candidate configurations with the desired performance, dynamic scaling and estimating the expected stability behavior with quantitative analysis of those identified configurations, developing a matrix of sub-scale models and test conditions to fully characterize the dynamic response of each configuration, and executing stability tests through the use of a ballistic range test facility. The data acquired from the tests will provide crucial insight moving forward regarding the feasibility and relative stability of each of the configurations and guide further development of rigid deployable aerodynamic decelerators. This proposed research lies directly in line with the call laid out in the technology roadmap for new technologies which aid in aerobraking, aerocapture, and entry of spacecraft. The potential of rigid deployable decelerators and other similar technologies to enable ground breaking advancements in the capability of our nation to explore hinges on the continuous efforts of researches to further understand their behavior. Stability characterization is just one piece of that effort, but is a step that is necessary to increase the technology readiness of the next generation aerodynamic decelerators which will allow for humans to step foot on Mars.

This dataset lists monthly station entry averages, by day type (Weekday, Saturday or Sunday/Holiday), as well as monthly totals, beginning in 2001. Note that some stations (such as on the Cermak Branch--now Pink Line) and Skokie did not have Saturday and/or Sunday/holiday service until more recent years, although, in cases where weekday service ran past midnight, late evening fares may appear as part of Saturday tallies.

Attitude determination of spin-stabilized platforms is especially challenging. Current low-cost gyroscope technology does not lend itself to attitude determination of platforms spinning in excess of one rotation per second. Traditional GPS-based attitude (GPS/A) sensors require three or more antenna elements separated by large baselines. Single-element designs require extensive calibration of the satellite signal-to-noise ratio (SNR) and are not very accurate. Toyon Research Corporation proposes to develop a small, single-aperture low-cost GPS/A sensor for space launch vehicles, and to demonstrate the sensor in an operational environment. The sensor determines the platform attitude with a single GPS antenna having a diameter of approximately 6.5 cm. The standalone performance of Toyon's GPS/A sensor on a spinning platform is better than 2.1 degrees for roll, and better than 1.2 degrees for yaw and pitch (one-sigma). The system performance can be further improved when integrated with accelerometers and/or magnetometers. Although current low-cost gyroscope technology does not allow their use on spinning platforms, non-spinning platforms may take advantage of gyro measurements for further improvements in attitude performance. During the proposed Phase II program Toyon will develop, build and test a prototype system that will be delivered for validation onboard an actual space launch vehicle.
