Episode 49 features Kathy Lueders, Manager of the Commercial Crew Program based at the Kennedy Space Center in Florida, and discussions of a brief history of the space program, how it started, and where it is now. Lueders talks about the two commercial companies, Boeing and SpaceX, and their space vehicles that will carry astronauts into low Earth orbit. This podcast was recorded on Wednesday, May 30th, 2018.
A conversation with Lynn Harper, who leads emerging commercial space efforts for the Space Portal office here at NASA's Ames Research Center in Silicon Valley, and Monsi Roman, who manages NASA’s Centennial Challenges program at the agency's Marshall Space Flight Center in Huntsville, Alabama.

MOCKINGBIRD NIGHT SONG: A Northern Mockingbird singing at night with crickets and gray treefrogs sounding off in the background. Recorded 11:30pm 27 May 2016, near Upperville, Virginia. © Lang Elliott. Microphone: quasi-binaural SASS (Stereo Ambient Sampling System) modified for use with Sennheiser MKH20 microphones. THE NORTHERN MOCKINGBIRD is well-known for its habit of singing at night. What most folks do not know is that the night-singers are primarily unmated males, which may sing almost continuously both day and night (especially when the moon is bright), in their quest to locate a mate. I managed to capture the featured recording during a recent expedition, which began with a social event: my partner’s niece was graduating from high school and we went down to attend the ceremony. Given how close we were to Washington D.C., I never imagined that I would get a usable recording (too many cars and jets). But we spent the night in a ranch house surrounded by large fields, and as luck would have it, there was a resident mockingbird that sang throughout much of the night. Resisting my urge to get some much-needed sleep (I was up until nearly 2am the night before, recording frogs), I ventured out around 11pm and walked a considerable distance to his singing tree, which was at the edge of a field. Crickets trilled gently from the grass and a chorus of Gray Treefrogs produced a drone from nearby forest, no doubt sounding off from a pond or swampy area. Not a bad catch for countryside near a major metropolis. Although not exactly a meditative recording, I am quite pleased to document night-singing in this species, along with enough ambient sounds to add spaciousness to the recording. This particular singer is doing some imitations, but the majority of his phrases seem to be of his own device. Rather than analyze his song phrases, I’ve chosen to simply enjoy the soundscape without thinking too much about it. Mockingbird Nightsong, delivered to you on a golden platter! What’ya think?
And beware the weird radio emissions Galileo gathered from Jupiter's largest moon, Ganymede.
This recording was produced by converting into audible sounds some of the radar echoes received by Huygens during the last few kilometers of its descent onto Saturn's moon Titan. As the probe approaches the ground, both the pitch and intensity increase. Scientists will use intensity of the echoes to speculate about the nature of the surface.

If you're squeamish, you may not want to listen to the strange whistle of ultra-cold liquid helium-3 that changes volume relative to the North Pole and Earth's rotation. When ultra-cold liquid helium-4 was squashed through an array of tiny apertures, a phenomenon occurred in which the helium-4 repeatedly sped up, slowed down and vibrated. This produced a "quantum whistle" -- a whistling sound that went from high to low.
This recording is a laboratory reconstruction of the sounds heard by Huygens' microphones - the probe that entered the atmosphere of Saturn's moon Titan. Several sound samples, taken at different times during the descent, are here combined together and give a realistic reproduction of what a traveller on board Huygens would have heard during one minute of the descent through Titan's atmosphere.

Episode 50 features Dr. Sarah Wallace who shares with us her instrumental role in developing the DNA sequencer used on the space station as part of a multi-center effort led here at the Johnson Space Center. DNA sequencing can be used for anything from monitoring the crew members' health to identifying microbes, and potentially detecting life in the solar system. This episode was recorded on April 17, 2018.

These melodious tones are created at a special frequency in a plasma with a magnetic field. The frequency is set by the number of electrons in a given volume (the electron density) and the strength of the magnetic field. Hence, the frequency of these waves, called upper hybrid waves, can provide a very accurate measure of the density of the plasma; a fundamental property of the Jovian environment of interest to scientists. These emissions were acquired by Voyager 2 as it passed through the outer magnetosphere in 1979.
