| NEAR Studies an Asteriod |
|---|

 |
The N.E.A.R. Space Craft Uses Remote Sensing to study the asteriod Eros.
|
| The space craft NEAR was launched in 1996 and flew in space for 4 years. See it's path. Click here to see the asteriods which NEAR visited during it's travels. |  |
 |
Eros is a large asteriod,
about 21 miles long. Click
here to see Eros spinning. And here's
how it looked as the NEAR spacecraft flew closer and closer to Eros.
Finally Spacecraft NEAR arrived at the asteriod named Eros.

| On February 14, 2000 the spacecraft NEAR began to orbit Eros. That was the first time in history that an Earth spacecraft orbited an asteriod!! | http://near.jhuapl.edu/NEAR/Education/images/NEAR_Rendezvous_Geom.gif

 |
Scientists want to measure and learn many things about an asteroid. But NEAR did most of its measurements WITHOUT TOUCHING Eros! How did NEAR measure things on Eros from a distance? NEAR studied Eros with special instruments. The instruments can 'see' different kinds of 'light' waves. Light is one kind of wave on the Electromagnetic Spectrum. |
NEAR used different kinds of Electromagnetic waves. Seven different instruments received the waves. Click on the picture to see a larger image.

Dr. Lucy McFadden is a scientist on the NEAR space craft project. Dr. McFadden helped to design this drawing. Dr. McFadden may send email to SOAR-High students about her experiences with NEAR this month. Watch for email from Lucy McFadden! |
