Deep Space Network

Messages from Juno and other spacecraft in the far reaches of the solar system are relayed to scientists via NASA’s Deep Space Network (DSN), which was created in 1958. DSN consists of three sets of powerful radio antennae spaced about 120 degrees longitude apart around the world near Barstow, Calif., Canberra, Australia, and Madrid, Spain. The complexes are all situated in bowl-shaped terrain in semi-mountainous rural areas to minimize interference from external radio waves. As Earth rotates, at least one of the DSN antennae is pointed toward the spacecraft at all times. Communications via DSN begin and end at NASA’s Jet Propulsion Laboratory, which manages the system.

Geomedia: Radio: "Big Picture Science" aptly named

Titles can sometimes be a hard thing to live up to, but “Big Picture Science,” a weekly radio program broadcast on about 100 stations nationwide, delivers on its name. The show, which cleverly covers everything from a study of frogs in pants to efforts to create a compassionate computer, lives up to its mission of presenting a wide-angle view of science and technology.

Why meteors snap, crackle and pop

Keen-eared observers sometimes report hearing popping, whistling or buzzing at the same time they see meteors pass far overhead, a perplexing phenomenon called the electrophonic effect. What causes the effect — or if it’s even real — has been discussed for centuries; famed astronomer Edmond Halley is said to have dismissed it as a figment of people’s imaginations. In a new study in Geophysical Research Letters, researchers suggest that not only is it real, but that it is caused by radio waves induced by meteors and converted to sound waves near Earth’s surface.

Geomedia: Radio: "The Infinite Monkey Cage" takes listeners to the edge of the universe and beyond

“Science is not about finding the right answer, it’s finding the least wrong answers,” quips physician and science writer Ben Goldacre, a guest on “The Infinite Monkey Cage,” a BBC radio show and podcast that casts an irreverent eye on big scientific questions. Goldacre was commenting on the definition of science, but this philosophy — that science is a constantly evolving pursuit, in which all ideas are valid until data and time prove them wrong — is also the refreshing and approachable premise of this witty show.
