3. Chandra Beauty Shot
These high definition artist's conceptions show a few different views of the Chandra X-ray Observatory. Chandra, one of NASA's "Great Observatories," has been operating in space since 1999. Chandra detects and images X-ray sources that lie within our Solar System to those billions of light years away. The results from Chandra help explore high-energy phenomena and provide insights into the Universe's structure and evolution.

5. Chandra Illustration with Earth
An artist's illustration of the Chandra spacecraft orbiting Earth. Chandra's orbit, which has the shape of an ellipse, takes the spacecraft more than a third of the way to the moon before returning to its closest approach to the Earth of 16,000 kilometers (9,942 miles). The time to complete an orbit is 64 hours and 18 minutes.

9. Chandra and the Deep Space Network
Data from Chandra are transmitted via the Deep Space Network stations to the Jet Propulsion Laboratory and from there to the Chandra Operations Control Center in Cambridge, MA.
Please note: In this illustration, Chandra's solar panels are positioned incorrectly to show entire working surface. Correctly positioned, the solar panels always face the Sun. Chandra's mirror aperture always faces away from the Sun (see image 2). (Illustration: CXC)
