Welcome to Scientist for a Day, an essay contest designed to give students a taste of life as a planetary scientist. Students in grades 5 to 12 are tasked to study three possible destinations, and then to write an argument in favor of revisiting one of them.
Gigi Stewart and Bryan Wong, two 8th-graders from St. Paul, Minnesota, wrote their best-in-class essay in favor of returning to Uranus’ moon Miranda. here

3%) to an oxidizer-rich gas generator that drives a LO2 TPA used to deliver the gasified LO2 to injectors positioned inside the afterburner nozzle downstream of the throat [18, 19, 20]. Here it mixes with the hot H2 and undergoes supersonic combustion adding both mass and chemical energy to the rocket exhaustessentially "scramjet propulsion in reverse." .
5 kWe) from the thermal output of the NTP reactor. 12 Having multiple kW of electrical power available in-situ would be enabling for a wide range of more capable science instruments, thermal management, increased data-transmission power/bit-rate, and would additionally reduce or eliminate the need for a RTG power source on deep-space missions. . here
Beyond the marine animal design, these fins are made from 100% vulcanized rubber that offer the right amount of flexibility and stiff strength. The fins have an ultra-elastic and soft foot pocket for a perfect, comfortable fit. You can get the fins in a wide range of sizes to perfectly match your body.
The fins were created with lifeguards in mind to offer a highly effective product that is quick and convenient to put on. The fins use a central reinforcement structure based on a marlins body to provide structure without weighing the fins down.
The material of the swim fins makes a big difference in their performance and durability. Swim fins are generally either made from rubber, silicone, or composite materials. Try to choose a pair of fins that offers enough comfort in a soft foot pocket, but enough strength in the blade for power. The material also affects the flexibility of the fin.
The full foot pocket is made from ultra-soft rubber for maximum comfort, while the blade uses medium-hard rubber for better propulsion. Different thicknesses and flexibility level of rubber are spread out across these fins, offering just the right level of stiffness where it’s needed. more
