Hopkins Ultraviolet Telescope Project

Astro-1 Astro-2

December 2, 2010, marked the 20th anniversary of the launch of Astro-1 on the space shuttle Columbia.

March 2, 2010, marked the 15 year anniversary of the launch of Astro-2 on the space shuttle Endeavour.

For the 15th Anniversary of Astro-1 in December 2005, we were able to gather for a celebration lunch at JHU. Here are some photos taken at this lunch.

Welcome to the home page of the Hopkins Ultraviolet Telescope (HUT) project at The Johns Hopkins University. HUT was conceived, designed, and built by astronomers and engineers at JHU to perform astronomical observations in the far-ultraviolet portion of the electromagnetic spectrum, wavelengths of light that are inaccessible to ground-based telescopes. The telescope flew twice aboard the space shuttle, once in December 1990 (Astro-1) and again in March 1995 (Astro-2), as part of a package of instruments called the Astro Observatory.

HUT's primary purpose was to observe wavelengths of light that are too short to be seen with the Hubble Space Telescope, although overlap was provided to allow direct comparison. HUT was used to observe hundreds of objects, ranging from nearby stars and planets to the most distant objects known in the Universe, the quasars.

Using the links below, you can access a wide range of popular level information about the telescope and its two space shuttle flights. Links to technical information are provided for those who are interested in more detail. We hope you enjoy browsing these pages and learning about HUT.

The People Who Made it Happen
Use this page to learn about many of the people involved in designing, building, and flying HUT on the space shuttle.

The Photo Gallery
Although photos are linked in elsewhere throughout our pages, we have assembled the best in one place! Check out images of the launches, the astronauts and telescopes on-orbit, and various earth views.

Also, peruse the Historical Photos page for scans of the Astro-1 and Astro-2 HUT Slide Sets, Earth Views, and scenes from the Payload Operations Control Cemter at NASA MSFC during each flight.

Technical Information About HUT
Project personnel (or interested bystanders) can use this link to get directly to technical information about the telescope and/or data reduction.

HUT Quick Look Spectral Atlas
Many of the spectra obtained with HUT during Astro-1 and Astro-2 are on-line. The top page contains links to "example" spectra of various types of objects for the casual user. A separate page allows you to search the actual observation log and select specific objects of interest.
