“…As reaching a certain altitude is crucial to a sounding rocket's operations, which provides test environments with micro gravity, low air density, and sufficient descending velocity with an adequate flight time, the final altitude is one of the most critical parameters of such a rocket's performance and is among the principal design objectives. Not only from this perspective, but also concerning operational efficiency, in light of a new aspect of cost-sensitive space technology emerging recently represented by such as low-cost and reusable launch vehicles [6][7][8][9][10][11][12], there is a greater need today for the maximisation of final altitudes and the minimisation of propellant masses of vertically launched flight vehicles.…”

A new type of design domain for a sounding rocket is suggested in this study, which is more intuitive, simplified, and conducive to a single-stage sounding rocket development process. Among the various operation parameters, this study identifies several effective variables, which are also among the most practical in a sounding rocket design process. Of the many design variables considered for peak altitude optimisation, arguably the three most effective in shaping the whole system and conferring the most practicality in the design process of a sounding rocket were determined. A simulation-based study was conducted to establish: the effect of the selected parameters on flight performance, and the optimum design conditions of a single-stage sounding rocket in terms of its peak altitude. The simulation result was compared with randomly chosen experimentally tested flight data and validated. With the clear performance curves varying depending on the variables, the combination of the considered design inputs was effective. The new type of design domain and design procedure proposed is expected to constitute a useful reference and deliver practical benefits to the development process for a target-altitude-optimised single-stage sounding rocket.

“…Whilst still hindered by the same depth issues (<5 m) radiometric issues that influence traditional satellites, with increased temporal frequency (daily) they provide greater opportunity for cloud-free, non-turbid, low, or high tidal, reduced wave conditions to be captured for greater coverage of coral reefs (Hedley et al, 2018;Joyce et al, 2018), increasing the spatial scale and resolution of ecological assessment from these satellites (Figure 3). Whilst currently limited by sensors and spectral bands (e.g., Red, Green, Blue, Infrared are standard output of rapid-return nanosatellites), the cost to produce (Kenyon and Stanton, 2017;Sarzi-Amade et al, 2017) these satellites is far less than traditional satellites.…”

Increasing sea surface temperature and extreme heat events pose the greatest threat to coral reefs globally, with trends exceeding previous norms. The resultant mass bleaching events, such as those evidenced on the Great Barrier Reef in 2016, 2017, and 2020 have substantial ecological costs in addition to economic and social costs. Advancing remote (nanosatellites, rapid revisit traditional satellites) and in-field (drones) technological capabilities, cloud data processing, and analysis, coupled with existing infrastructure and in-field monitoring programs, have the potential to provide costeffective and timely information to managers allowing them to better understand changes on reefs and apply effective remediation. Within a risk management framework for monitoring coral bleaching, we present an overview of how remote sensing can be used throughout the whole risk management cycle and highlight the role technological advancement has in earth observations of coral reefs for bleaching events.
