I Love the '90s -- at least 1999

Jul
21

Nine years ago this week, Chandra was launched aboard the Space Shuttle Columbia (sadly lost in the tragedy of 2003). While the satellite has performed excellently since it was deployed on July 23, 1999, there was a little drama in getting it going. You can read about some of the angst-inducing moments in the days leading up to launch in our Chandra Chronicles from that time.

Part of the Smithsonian Folklife Festival Series:
Hearing rumors about the Bhutanese prince's presence around the Smithsonian Folklife Festival was exciting. I spoke with other members from the NASA group about the etiquette when being nearby or meeting the prince. For the next week there would be hundreds of NASA and NASA related scientists, engineers, managers, and other personnel volunteering their time to talk about what they do and what drives them.

Cosmic Fireworks

Jun
30

This week, many Americans will celebrate the 4th of July by enjoying fireworks. We love to see the explosion, followed by the colorful debris field as it expands and rains down from the sky. And, fireworks are often slightly different from one another – even if they originate from the same type of explosion. Of course, if they have different types or proportions of chemicals before in the explosive itself, the fireworks can look dramatically different. And, don’t forget that the environment they explode into – include wind or clouds of smoke – can affect how they look.

Now or Then: Explaining Light Travel Time

May
27

With the press release for G1.9+0.3 we talked about when an event in a distant part of the Milky Way galaxy occurred. One delicate issue that immediately came to mind was what to do about the light travel time to this object. We decided to adopt the astronomer's convention and talk about events in Earth's time frame, that is when the light reached the Earth, as we noted in the press release and in a few other places on our web-site.
