Color Your Own Worlds

Though we just missed National Coloring Book Day, we wanted to bring this cool educational product to your attention. The Transiting Exoplanet Survey Satellite (TESS) mission just put out an exoplanet coloring book, aimed at kids ages 5-10. (But of course, we won’t tell anyone if you want to color … Continue Reading →

Explore @ NASA Goddard redux

It’s a Thursday, and we are throwing back to September! Why? Because we never got around to reporting back on the huge NASA Goddard Open House, where we threw open our gates and 20,000 members of the public got to come in and see exactly what it is we do … Continue Reading →

I was recently asked why the James Webb Space Telescope (a large infrared observatory) won’t have X-ray or gamma-ray detectors on board. Wouldn’t it be good for such a telescope to be able to see more than just infrared? In order to see the full range of the electromagnetic spectrum, … Continue Reading →

There are great observatories – and then there are “Great Observatories,” a title given to four space telescopes launched in the 1990s/early 2000s, each studying a different wavelength of light. The Hubble Space Telescope, primarily looking at visible light, you are likely familiar with; it was the first launched and … Continue Reading →

Mirror, Mirror

When last I updated, the James Webb Space Telescope’s primary mirror was under construction here at NASA Goddard. I believe we were on mirror segment number five. I’m very pleased to say that the primary mirror assembly was officially completed on February 3, 2016! Here are a few more photos … Continue Reading →


The heart of the ASTRO-H Soft X-ray Spectrometer is the microcalorimeter array at center. The five-millimeter square forms a 36-pixel array. Each pixel is 0.824 millimeter on a side, or about the width of the ball in a ballpoint pen. The detector's field of view is approximately three arcminutes, or one-tenth the apparent diameter of the full moon.

  • Comments Off on Five Questions about ASTRO-H/Hitomi (and launch videos!)

We were able to get our hands on these “5 questions your neighbor might ask” about the ASTRO-H mission (recently renamed Hitomi), and in particular NASA Goddard’s contributions. Here are the answers, courtesy of Dr. Rich Kelly, the Principal Investigator of the Soft X-ray Spectrometer (SXS). [Fun fact – he … Continue Reading →


ASTRO-H Launches

A New Eye in Space

It’s with greatest pleasure that we say congratulations to the whole ASTRO-H team for a successful launch. Or should we say, the Hitomi team. ASTRO-H has been newly re-christened, as is the Japanese tradition upon a successful launch. The name Hitomi has a significance, and that is this. According to … Continue Reading →
