Abstract

Investigation of Uranus and Neptune, via orbiter and atmospheric probes, is required to answer pressing science questions that have been raised in previous Decadal Surveys. As the Ice Giants are the farthest planets from Earth, traditional fully-propulsive orbit insertion missions would require a large amount of propellant, leaving less mass for the scientific payload; additionally, transit time to the planetary bodies near 13-15 years. Aerocapture uses aerodynamic forces generated by flight within a planetary atmosphere to decelerate and achieve orbit insertion. Although, aerocapture has not been used in the past, recent developments in thermal protection systems, guidance and control, and navigation capabilities enable the use of rigid, heritage entry vehicle configurations already flown at other planetary bodies for Ice Giants aerocapture. With the addition of these recent capabilities, aerocapture can robustly deliver spacecraft to Ice Giant orbits, while substantially increasing on-orbit payload mass (more than 40%) and reducing the transit time by 2-5 years (15-30%) relative to fully-propulsive orbit insertion.

5. The CESAR project during the COVID pandemic

Author

Sandra Benitez Herrera, Juan Angel Vaquerizo, Miguel Perez Ayucar, Beatriz Gonzalez, and David Gonzalez Lopez-Tercero

Abstract

CESAR (Cooperation through Education in Science and Astronomy Research) is a joint educational initiative between ESA (European Space Agency), INTA (Spanish National Institute for Aerospace Technology) and ISDEFE (Spanish state-owned consulting and engineering Company). Its main goal is to engage school students with STEM disciplines through the wonders of the Universe. The CESAR programme offers teacher training courses on Astronomy and Planetary Science topics to provide hints and inspiration for the use of space in school lessons to European educators and allow them to interact with scientists and experts too. These trainings had to be fully adapted to a virtual format due to the pandemic caused by the Covid-19 in a very short time scale. Moreover a complete set of online activities, the so-called Space Science Experiences (SSE), was develop during this period for primary and secondary schools, providing them with different educational resources, such as: online labs, virtual tours, access to scientific data from ESA space missions, proposal of experiments…all within the inquiry-based learning framework. In this talk we will explain the process of design, development and classroom application of the on-line SSEs and present the lessons learned and success from this virtual approach.
