HETE 1

NASA’s HETE 1 (High Energy Transient Explorer 1) mission was to have been an international mission to carry out the first multiwavelength study of gamma-ray bursts using ultraviolet, X-ray, and gamma-ray instruments. The launch vehicle’s upper stage failed to release the satellite, which lost all power several days after launch.

An object in the image has two lobes connected by a narrow, curved "neck," giving it a duck-like appearance. The object’s surface is rough and textured, with a mix of craters, rocky protrusions, and uneven, rugged terrain. Bright streams of material radiate outward from the surface, creating a soft, fan-like glow around the object. In contrast to the bright object, the image background is black.
The image depicts the interior of an observatory dome with a large opening through which daylight is visible. The dome structure consists of curved metallic panels that meet at the top, with one panel slightly open on the left side, revealing a cross-braced metal framework. In the foreground, a person stands on a ladder inside the dome, wearing a casual T-shirt with a prominent logo. The person is looking upward toward the opening, partially illuminated by the ambient light. Behind them is an array of mechanical equipment, possibly part of the dome’s operation system. The overall color scheme is composed of metallic grays and earth tones from the dome's surfaces.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
