Learners will measure the diameter of a solar flare by making calculations using transparency grids overlaid on images of the Sun. This is the third activity in the lesson "How Does HESSI Take a Picture?" **NOTE: The HESSI mission was renamed... (View More) RRHESSI (Reuven Ramaty High Energy Solar Spectroscope Imager)** after Dr. Reuven Ramaty, who was the original Co-Investigator for this NASA mission, and was a pioneer in the fields of solar physics, gamma-ray astronomy, nuclear astrophysics, and cosmic rays.

This is an activity about determining the distance of a solar flare from the center of the Sun's disk. Learners will use transparency grids overlaid on images of the Sun in order to calculate the distance of a solar flare, similar to a signal... (View More) detection method used by scientists. This is the second activity in the lesson "How Does HESSI Take a Picture?" **NOTE: The HESSI mission was renamed RRHESSI (Reuven Ramaty High Energy Solar Spectroscope Imager)** after Dr. Reuven Ramaty, who was the original Co-Investigator for this NASA mission, and was a pioneer in the fields of solar physics, gamma-ray astronomy, nuclear astrophysics, and cosmic rays.

Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature measurements, and plot the results. Extensions include experimenting with different materials, using temperature sensors and... (View More) noncontact infrared thermometers. The activity is analogous with remote sensing of thermal properties in the Saturn system measured by Cassini. (View Less)

This activity is about the discovery of water ice on Mars. Learners will record and graph temperature data and use a model of an ice-rich and ice-free surface on Mars to examine how ice content in the martian soil would impact the temperature of a... (View More) Mars microbe after impact. A student information sheet introducing the subject of ice and the search for water on Mars is provided. The activity requires access to a freezer the night before the activity. **Note: Find the latest information and updates on Mars missions at the NASA Mars Exploration website (see Related & Supplemental Resources to the right).** (View Less)
