ISS Science for Everyone

Science Objectives for Everyone
NanoRacks DreamUp Xtronaut Crystal Growth (DreamXCG) teaches students about the effects of microgravity on crystal formations using near-identical flight kits flown and operated aboard the International Space Station (ISS). With access to crew member videos and data on the same experiment, students are able compare crystal formations in space to those in their classrooms. The investigation aims to promote science, technology, engineering, and math (STEM) fields to the next generation of students.

Experiment Description

Research Overview

  • The objective of NanoRacks-DreamUp Xtronaut Crystal Growth (Dream XCG) is to engage learners around the globe and inspire the next generation of students to participate in science, technology, engineering, and mathematics (STEM) fields, especially those in grades 5 through10.
  • Learners have many questions about microgravity, such as how crystals grow in space, and how they are similar and unique from crystals that grow in their homes and schools on Earth.
  • Learners have a chance to grow their own crystals and compare them to crystals grown and obtained aboard the ISS.

NanoRacks DreamUp Xtronaut Crystal Growth (DreamXCG) is a kit designed to teach students about the similarities and differences of crystal growth in microgravity on the International Space Station (ISS) and in their own homes/schools. Students use ground kits and, via an online portal, are granted access to videos and data from a near-identical flight kit flown and operated on the ISS. Once the NanoRacks-DreamUp Xtronaut Crystal Growth (DreamXCG) experiment arrives on station, astronauts insert hot water that they use to warm their own victuals into the “ready to go” pouches with the growth materials. Photos are taken of the crystal growth at regular intervals.

Space Applications
The investigation inspires the next generation of space explorers by displaying the ISS and its unique environment. Upon completion, investigators are able to evaluate the efficiency of the project and make improvements for future education projects aboard the ISS.

Earth Applications
The experiment establishes a connection between learners and the space program. In light of the effects of microgravity, learners are made aware of the effects of gravity and how it plays a role in their everyday lives. Moreover, the project inspires learners to enroll in STEM subjects and pursue STEM-related careers

Operational Requirements and Protocols
The drinking water container is filled with 100 mL of 82°C of water. Using a straw assembly with an adapter probe on both ends, the water is transferred in the drinking water container to the sugar pouch assy. The mixture is shaken vigorously until the sugar in the pouch is dissolved. Using a straw assembly with an adapter probe on both ends, the mixture is transferred from the sugar pouch assy to the crystal pouch assy. Crew periodically checks on the pouches and takes pictures. Pictures are to be taken once at 24 hr, 48 hr, and then every 2 days after that for a total of 14 days. The kit is disposed of when the mission is complete.
