Aerospace Team ONLINE
UPDATE # 2 - November 26, 1997
PART 1: Biographies and Field Journals
bring to life the real world excitement of America's aerodynamic design and research program. Almost 25 biographies of the people involved are available, so far. Each person tells a bit about their day-to-day responsibilities and their (often convoluted) career path which led them to their present position. Many articles include personal information like family facts and hobbies. Others have details about the NASA person as a youngster. This material puts a personal face on the action, and tries to help your students visualize a path they might take to one day work at NASA themselves. Also, every week we will publish one or more so called "Field Journals." These stories will describe in detail the work it takes to make the shuttle and space station come to life. The format will vary, and may include "what I did today," or "a problem I recently solved," or a "problem I wish I could solve," or "my goals for the next month." Regardless of the style, the stories should help you and your students understand the diversity of skills and people needed for NASA's aerodynamics design and research. These materials are written at middle school or older reading levels. We hope that these snippets of NASA's world will be useful as reading exercises and to illustrate related topics within your curriculum.
EMAIL QUESTIONS WHICH GET PERSONALLY ANSWERED
NASA's Aerospace Team is available. In most cases, you will receive a direct reply within 10 days to two weeks. K-12 students and teachers can email questions to engineers, scientists and support staff. This interaction will be supported by a "Smart Filter" which protects the professional from Internet overload by acting as a buffer. The actual email addresses of these experts will remain unlisted. Also, repetitive questions will be answered from an accumulating database of replies; thus the valued interaction with the experts will be saved for original questions. We believe that the email Q&A service is a good compliment to the bios, Field Journals and other materials. Students have an opportunity to follow-up on any Aerospace Team Online information, or they can pursue their own lines of interest.
WEBCHAT WITH ESTELA HERNANDEZ
we had some terrific questions asked and got some insightful answers. The archive of past chats is now in place, and will be kept up to date. The best part of chats, though, is being in touch LIVE with the expert, so join us for an exciting hour of give and take about aeronautics and related subjects. Our upcoming chat will feature: Tuesday, December 2, 10:00-11:00 a.m. Pacific Time: Estela Hernandez, Flight Simulation Engineer, Estela is works at the world's largest motion simulator. Right now she's working on a simulation for the Space Shuttle which the astronauts will try flying in February. Read her bio at http://quest.arc.nasa.gov/aero/team/hernandez.html To participate (ask questions), you will need to pre-register for the individual chats. Go to: http://quest.arc.nasa.gov/aero/chats
BUILDING A NEW RADAR ALTIMETER MODEL
November 24, 1997 The radar altimeter measures the altitude of an aircraft by measuring the echo of a radio wave to return and the direction from which it returns. The radar altimeter provides an accurate indication of altitude of the Space Shuttle from 5,000 ft. to touchdown. We are trying to update the Space Shuttle model to make the radar altimeter more accurate. Currently, I am looking at the math model and trying to compare it to our Space Shuttle simulation. This is being done at the same time as the implementation of global positioning system (GPS). Eventually, with both of these instruments working accurately the astronauts will have more precise information. The math required for the implementation of the model is basic calculus and physics. This is how the model simulates the changes in altitude. The scientists are NASA employees as well as contractors from Houston and Los Angeles. The scientists design and check the model. Then, they send us the model with their checks so we can match them with ours. This will allow us to make sure that it is accurately modeled. This simulation will take place in February when the astronauts will fly the new radar altimeter model at the Vertical Motion Simulator. The astronauts will fly approach and land usually starting at about 10,000 ft. As a simulation engineer, one of my responsibility is to fly the simulator to make sure everything is working property. While the project is challenging it is also very interesting. If I run into problems there is always someone who I can turn to for help.
