Remembering Columbia

Feb
01

Nine years ago today, we experienced a terrible tragedy. On February 1, 2003, the seven-member crew of STS-107 was lost when the Space Shuttle Columbia disintegrated over Texas and Louisiana on its re-entry into Earth's atmosphere.

Astronomy Show Down in Texas

Jan
09
AAS Texas

This 219th meeting of the American Astronomical Society meeting is under way this week in Austin, TX. There will be lots of scientific talks, posters, and in-the-hallway discussions between the 2,700 astronomers who have come to Texas for the meeting. (That's quite a bit when you consider there are probably only several thousand professional astronomers in the whole US!)

Of course, there are lots of Chandra results being shared. Tomorrow, there will be a press conference to announce some exciting new findings involving Chandra and some of the largest objects in the Universe. We'll have the news posted on our website at 10am Central so check back for the latest in the X-ray Universe.

Changing of the Guard at NASA Science

Jan
04

Today, a new leader reports to NASA HQ to take over what is known as the Science Mission Directorate, or SMD. SMD is the branch of the agency that is responsible for all things science at NASA - from heliophysics to Earth science to planetary science and astrophysics. Chandra, as well as the other "Great Observatories" missions of Hubble and Spitzer, and many, many missions belong to the astrophysics realm of SMD.

STOP at the NSTA

Dec
13

One of the projects that we're very excited around here is something called "Stop for Science!" (aka, STOP). This is a program aimed at engaging kids outside of classroom time in thinking about science. STOP is meant to be fun, but also informative. The centerpiece of the program is a series of five posters covering different areas. The topics range from "how tall is tall" to "when stars go boom." Each poster has accompanying material including background information, questions for different ages of kids, and teacher resource guides.

Happy Trails, MSL

Nov
28

While most of us in the US were still digesting from the Thanksgiving holiday this past weekend, many folks at NASA were incredibly busy. That's because on Saturday, November 26th, NASA launched the Mars Science Laboratory (MSL) into space aboard an Atlas V rocket.

Changing the way we view the world

Nov
03

An era of space exploration ended on July 21, 2011 when Space Shuttle Atlantis touched down before dawn at Kennedy Space Center. The shuttle flights excited our imaginations and tragically revealed the dangers of space travel as mankind dipped its toes into the cosmic ocean. One of the most enduring legacies of the shuttle was established in the 1990's, when the shuttle delivered three of NASA's Great Observatories – Hubble Space Telescope, Compton Gamma Ray Observatory, and the Chandra X-ray Observatory – into space.

Rest in Peace, ROSAT

Oct
31

Last week, the German Aerospace Center (DLR) issued this statement:

"On 23 October 2011 at 03:50 CEST, the German research satellite ROSAT re-entered the atmosphere over the Bay of Bengal; it is not known whether any parts of the satellite reached Earth's surface. Determination of the time and location of re-entry was based on the evaluation of data provided by international partners, including the USA."

Chandra's Digital Legacy

Oct
24

October is American Archives Month—a time to celebrate the importance of archives across the country. In honor of Archives Month, we're participating in a pan-Smithsonian blogathon. Throughout October we, and other blogs from across the Smithsonian, will be blogging about Chandra's rich archive of astronomical data, issues, and behind-the-scenes projects. Check out the RSS feed of blogathon posts from across the Smithsonian.

----------------------------------------------------------------------------------------------------------------------------------------------------------

Concluding our series of Archives Month blog posts, we thought we'd shift our focus towards the future of Chandra's digital legacy. Although the modern marvel of engineering that is the Chandra X-ray Observatory will not last forever, its lasting gift to humanity will be its archive of data. Long after the last bits of X-ray light have found their way to Chandra's detectors, scientists and curious amateurs will still be pouring over Chandra's archival data looking for their particular X-ray needle in the digital haystack.

A Summer of Sleuthing Around Hot Data

October is American Archives Month—a time to celebrate the importance of archives across the country. In honor of Archives Month, we're participating in a pan-Smithsonian blogathon.

----------------------------------------------------------------------------------------------------------------------------------------------------------

This past summer, I interned in the Chandra Education and Public Outreach department at the Smithsonian Astrophysical Observatory (SAO), where I spent several months sleuthing around the Chandra data archives as part of an on-going Astronomy Visualization Metadata (AVM) tagging project http://www.virtualastronomy.org/. AVM is data embedded into each image of astronomical objects that includes information such as the objects coordinates, the instrument and instrument settings used for capturing the image, and a description of the image. The goal of the project is to tag all the press release images from the Chandra X-ray telescope with metadata.
