Thanks for Everything, Atlantis and Endeavor

Launch Chandra

As the human spaceflight plans at NASA transition away from the Shuttle program, there have been lots of goodbyes. And hellos. Recently, both the Space Shuttles Atlantis and Endeavor found new permanent homes in their post-flight lives. Atlantis is now at the Kennedy Space Center Visitor Center in Florida, and Endeavor will be found from now on at the California Science Center in Los Angeles.

At each location, NASA held a welcome home/retirement party for the Shuttles. As we've talked about before , the Shuttle program did so much more than just take people into space (which, of course, is a very important job). It also delivered many unique and important telescopes and instruments into orbit – including the Chandra X-ray Observatory.

A Space Jigsaw Puzzle: Coordinating Chandra With Other Telescopes

In July 2012, an event took place that gives us a chance to talk about several important aspects of Chandra observations involving coordination with other observatories, how they are done, and how they fit into the bigger picture of astronomical research.

Jigsaw Puzzle

Coordinated observations are those that must be done by Chandra and one or more other observatories at approximately the same time. Astronomers often want to study objects with multiple observatories because their different capabilities --- especially in detecting different regions of the electromagnetic spectrum --- can provide insight that no single observatory can do alone. The need for coordination in time comes because so many objects in space vary over time. That means that observations taken too far apart could be less valuable because the object has changed substantially in the meantime. It's often important for all observatories involved to catch the object during a particular celestial event. In the current annual cycle, Chandra's 13th , for example, about 10% of the approved observations request coordination with another observatory.

Going Back to School

This week marks the return to school for most kids (if they haven't been there for a week or more already). The post-Labor Day week got us thinking about school and education as it relates to Chandra and X-ray astrophysics.

"Here, There, and Everywhere" Makes its Debut

Today marks the launch of a new project – both physically and virtually. We are so happy to announce that "Here, There, and Everywhere" (known by the acronym of HTE) has officially debuted.

You may have heard this question, or asked it yourself: why bother studying things that are millions or billions of miles away in space? HTE, among other things, is a project that addresses that question.

LUCKY 13

A little bit after midnight (12:31 am EDT to be exact) on July 23, 1999, the Space Shuttle Columbia lifted off from the Kennedy Space Center in Florida. Onboard was what was then the largest payload ever carried by a Shuttle: the Chandra X-ray Observatory.

Welcome Home, Shuttle Discovery

This morning, the Space Shuttle Discovery touched down from its final flight – a journey from the Kennedy Space Center in Florida to Washington, DC. Discovery will eventually be on display at the Smithsonian's Udvar-Hazy Center near the Dulles airport.

Chandra's own Roger Brissenden was on hand in Washington, DC, for today's event. Chandra has connections to this event on both the NASA and the Smithsonian sides.
