Jupiter Mission (02:36)

FREE PREVIEW

NASA launched the Juno space probe five years ago; experts wait for the spacecraft to enter orbit. Learn about the planet’s extraordinary features. Dr. Graham Phillips explains why Australia is best positioned for communication.

Jupiter's Mysteries (02:06)

Dr. Jasmina Lazendic-Galloway and Dr. Daniel Price explain what causes the planet's extreme weather. The Juno spacecraft will use a microwave radiometer to see under the Great Red Spot and probe the surface atmosphere's depth.

Entering Jupiter's Orbit (02:53)

Phillips visits the Juno Mission control room in Tidbinbilla, Australia. They work with NASA's Goldstone and Canberra stations to maintain communication and guide the spacecraft into orbit; the biggest challenge is the planet's harsh environment.

Jupiter's Aurora Borealis (02:40)

Engineers encased Juno's instruments in a titanium vault to protect them from radiation. Before being destroyed to protect Europa from Earth microbial contamination, the spacecraft will investigate the planet's magnetic field—the largest force in the solar system.

Planetary Formation (04:36)

Solar systems are born in gas fields like the Orion Nebula. New telescope technology allows us to look into the dusty disks around newborn stars. Theory predicts that big planets should form far from their stars; some experts believe Jupiter is a failed star. The Juno spacecraft successfully enters orbit.

Recording Nature (03:05)

Hear a beaver mourning his lost family. Small digital recorders are transforming the field of soundscape ecology and allowing scientists like Professor David Watson to observe nature without disturbing it. They can document desert green seasons or be alerted to invasive species.

Soundscapes and Biodiversity (02:33)

Jessie Cappadonna uses digital recorders to look for the Eastern bristlebird, an endangered species. Eddie Game listens for changes to the Papua New Guinea forest from deforestation and climate change.

Acoustic Niche (03:35)

Michael Towsey translates digital soundscapes into spectrograms that plot acoustic energy on graphs. Bernie Kraus developed the theory that insect and animal species occupy specific vocal frequencies. As anthrophony increases, biophony decreases.

Visualizing Soundscapes (04:00)

Towsey uses satellite data decoding technology to compress and color code spectrogram data. Comparing acoustic signatures from two sites inspired him to transform data into concentric squares showing distinctive patterns, such as habitat loss. Kraus says that 50% of habitats in his archive no longer exist.

Description

The natural world tells unseen stories through sound. All are fascinating but also disturbing. This new science of soundscape ecology is tracking environmental change with small audio recorders and powerful computer processing. Catalyst discovers what we can learn from listening to nature. It’s a perilous journey for the NASA spacecraft, Juno. Jupiter has the harshest radiation of any planet in the solar system and the strongest magnetic field. It has storms that rage for centuries and the strongest gravity. The environment is so harsh, Juno’s delicate scientific instruments need a special protective titanium vault to shield them. Catalyst goes to Australia’s tracking station Tidbinbilla to witness Juno going into orbit around Jupiter and begin its mission. Will it reveal new information about the birth of our solar system?
