Class Science Fair Projects on Rockets

During this week’s NASA Now program, you’ll meet Michael Studinger, Project Scientist for Operation IceBridge. He’ll describe the purpose of the IceBridge campaign and how the campaign objectives will be met. He also explains why studying Earth’s ice is important for understanding climate changes and how they related to humans.
Check out part 2 of the NASA Now: A-Train series and learn how NASA uses a constellation of satellites called the A-Train to monitor the Earth system. Five NASA satellites comprise the A-Train. They fly over the same location on Earth within 15 minutes of each other collecting data about the current state of the components of the Earth system.

NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California’s Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components.
The results of this study will inform ongoing research in many areas, including the study of Earth’s evolution, organic chemistry, biogeochemical cycles, disease mitigation and Earth system research. These findings also will open up new frontiers in microbiology and other areas of research.
“The idea of alternative biochemistries for life is common in science fiction,” said Carl Pilcher, director of the NASA Astrobiology Institute at the agency’s Ames Research Center in Moffett Field, Calif. “Until now a life form using arsenic as a building block was only theoretical, but now we know such life exists in Mono Lake.”

NASA will hold a news conference at 2 p.m. EST on Thursday, Dec. 2, to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life. Astrobiology is the study of the origin, evolution, distribution and future of life in the universe.
The news conference will be broadcast live on NASA Television and streamed on the agency’s website at https://www.nasa.gov/ntv.
Participants are:
– Mary Voytek, director, Astrobiology Program, NASA Headquarters, Washington
– Felisa Wolfe-Simon, NASA astrobiology research fellow, U.S. Geological Survey, Menlo Park, Calif.
– Pamela Conrad, astrobiologist, NASA’s Goddard Space Flight Center, Greenbelt, Md.
– Steven Benner, distinguished fellow, Foundation for Applied Molecular Evolution, Gainesville, Fla.

Students and teachers have an opportunity to learn about the wide variety of career choices at NASA — astronauts aren’t the only folks who work at NASA! NASA employees representing various projects and missions will be in the Digital Learning Network studios for a series of webcasts focusing on careers. They will share their academic experiences from elementary school through college and talk about what motivated them to pursue their careers.
Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
During this episode of NASA Now, you’ll meet NASA physical scientist Lin Chambers, learn about the role of clouds in the Earth’s energy and water cycles, and find out how NASA collects cloud data. Understanding the impact of clouds is an important key to predicting how Earth’s climate may change in the future. Currently, five Earth observing satellites, known as the “A-Train” orbit the Earth. These satellites orbit in formation, following each other and barrel across the equator at about 1:30 p.m. local time each day. This behavior gives the constellation of satellites its name: The “A” stands for afternoon. By combining different sets of nearly simultaneous observations from these satellites, scientists are able to study important parameters related to climate.
