As the PACE mission nears the end of its environmental testing, Gary Davis enlists the help of the US Marine Band to see if musicians can match the acoustic levels the spacecraft faced in testing.

ALT This image layout of galaxy M87 contains four images. Along the top are three images in different wavelengths of light. From the left, an image labeled radio shows a bright source in the middle with two prominent swirls of red jets extending outward to the left and outward and down toward the right. The second image, labeled optical, shows a very bright elliptical galaxy in mostly white, with a jet extending to the right from the center of the galaxy. The third image, labeled X-ray, shows the galaxy and jets, in shades of blue. Jets extend outward to the left and outward and down toward the right. The jet on the right is more than 100,000 light-years long. The fourth image at the bottom is a composite of radio, optical, and X-ray light, a multiwavelength image that combines the observations of three observatories.
