NASA’s Juno to Get Close Look at Jupiter’s Volcanic Moon Io on Dec. 30

The orbiter has performed 56 flybys of Jupiter and documented close encounters with three of the gas giant’s four largest moons.

NASA’s Juno spacecraft will on Tuesday, Dec. 30, make the closest flyby of Jupiter’s moon Io that any spacecraft has made in over 20 years. Coming within roughly 930 miles (1,500 kilometers) from the surface of the most volcanic world in our solar system, the pass is expected to allow Juno instruments to generate a firehose of data.

“By combining data from this flyby with our previous observations, the Juno science team is studying how Io’s volcanoes vary,” said Juno’s principal investigator, Scott Bolton of the Southwest Research Institute in San Antonio, Texas. “We are looking for how often they erupt, how bright and hot they are, how the shape of the lava flow changes, and how Io’s activity is connected to the flow of charged particles in Jupiter’s magnetosphere.”

A second ultra-close flyby of Io is scheduled for Feb. 3, 2024, in which Juno will again come within about 930 miles (1,500 kilometers) of the surface.

The spacecraft has been monitoring Io’s volcanic activity from distances ranging from about 6,830 miles (11,000 kilometers) to over 62,100 miles (100,000 kilometers), and has provided the first views of the moon’s north and south poles. The spacecraft has also performed close flybys of Jupiter’s icy moons Ganymede and Europa.

“With our pair of close flybys in December and February, Juno will investigate the source of Io’s massive volcanic activity, whether a magma ocean exists underneath its crust, and the importance of tidal forces from Jupiter, which are relentlessly squeezing this tortured moon,” said Bolton.

Now in the third year of its extended mission to investigate the origin of Jupiter, the solar-powered spacecraft will also explore the ring system where some of the gas giant’s inner moons reside.

Picture This

All three cameras aboard Juno will be active during the Io flyby. The Jovian Infrared Auroral Mapper (JIRAM), which takes images in infrared, will be collecting the heat signatures emitted by volcanoes and calderas covering the moon’s surface. The mission’s Stellar Reference Unit (a navigational star camera that has also provided valuable science) will obtain the highest-resolution image of the surface to date. And the JunoCam imager will take visible-light color images.

JunoCam was included on the spacecraft for the public’s engagement and was designed to operate for up to eight flybys of Jupiter. The upcoming flyby of Io will be Juno’s 57th orbit around Jupiter, where the spacecraft and cameras have endured one of the solar system’s most punishing radiation environments.

“The cumulative effects of all that radiation has begun to show on JunoCam over the last few orbits,” said Ed Hirst, project manager of Juno at NASA’s Jet Propulsion Laboratory in Southern California. “Pictures from the last flyby show a reduction in the imager’s dynamic range and the appearance of ‘striping’ noise. Our engineering team has been working on solutions to alleviate the radiation damage and to keep the imager going.”

More Io, Please

After several months of study and assessment, the Juno team adjusted the spacecraft’s planned future trajectory to add seven new distant Io flybys (for a total of 18) to the extended mission plan. After the close Io pass on Feb. 3, the spacecraft will fly by Io every other orbit, with each orbit growing progressively more distant: The first will be at an altitude of about 10,250 miles (16,500 kilometers) above Io, and the last will be at about 71,450 miles (115,000 kilometers).

The gravitational pull of Io on Juno during the Dec. 30 flyby will reduce the spacecraft’s orbit around Jupiter from 38 days to 35 days. Juno’s orbit will drop to 33 days after the Feb. 3 flyby.

After that, Juno’s new trajectory will result in Jupiter blocking the Sun from the spacecraft for about five minutes at the time when the orbiter is at its closest to the planet, a period called perijove. Although this will be the first time the solar-powered spacecraft has encountered darkness since its flyby of Earth in October 2013, the duration will be too short to affect its overall operation. With the exception of the Feb. 3 perijove, the spacecraft will encounter solar eclipses like this during every close flyby of Jupiter from now on through the remainder of its extended mission, which ends in late 2025.

Starting in April 2024, the spacecraft will carry out a series of occultation experiments that use Juno’s Gravity Science experiment to probe Jupiter’s upper atmospheric makeup, which provides key information on the planet’s shape and interior structure.

More About the Mission

JPL, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott J. Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. Lockheed Martin Space in Denver built and operates the spacecraft.

Studying Combustion and Fire Safety

Research on the International Space Station is helping scientists to understand how fire spreads and behaves in different environments and learn how to prevent and extinguish fires in space. Combustion investigations contribute to the safety of crew members, equipment, and spacecraft by guiding selection of spacecraft cabin materials, improving understanding of fire growth, and identifying optimal fire suppression techniques. This research also contributes to fire safety on Earth and some studies improve our understanding of combustion for uses such as producing electricity and powering vehicles on the ground.

Microgravity dramatically influences flames and provides a unique environment for studying combustion. For example, on Earth, hot gases from a flame rise and gravity pulls cooler, denser air to the bottom of a flame, creating the classic shape and flickering effect. In microgravity, this flow doesn’t occur and on the space station, low-momentum flames tend to be rounded or even spherical. By removing the effects of buoyancy, microgravity provides researchers a better understanding of specific flame behaviors.

The Combustion Integrated Rack (CIR), developed and operated by NASA’s Glenn Research Center, provides a secure and safe environment for a wide range of combustion experiments. Different chamber inserts that enable a variety of investigations include the Multi-user Droplet Combustion Apparatus, which supported FLame Extinguishment Experiments (FLEX), the Advanced Combustion via Microgravity Experiments (ACME) insert, and the Solid Fuel Ignition and Extinction – Growth and Extinction Limit (SoFIE) chamber.

FLEX, which analyzed the effectiveness of fire suppressants, led to the discovery of a type of cool flame, where the fuel continued “burning” under certain conditions after extinction of the visible flame. Typical flames produce carbon dioxide and water, but cool flames produce carbon monoxide and formaldehyde. Learning more about the behavior of these chemically different flames could lead to the development of more-efficient, less-polluting vehicles. Cool flames produced on Earth quickly flicker out. Since they burn longer in microgravity, scientists have the opportunity to study them.

FLEX-2 looked at how quickly fuel droplets burn, the conditions required for soot to form, and how mixtures of liquid fuels evaporate before burning. Results could help make future spacecraft safer and increase fuel efficiency for engines using liquid fuel on Earth.

ACME is a set of six independent studies using the CIR to examine fuel efficiency and pollutant production in combustion on Earth. The series also looked at improving spacecraft fire prevention through a better understanding of materials flammability.

One ACME investigation, Flame Design, studied the quantity of soot produced under different flame conditions. Soot, the carbon residue left when carbon-containing material does not fully burn, causes environmental and health issues but is desirable for some purposes. Results could enable the design of flames with more or less soot, depending on the specific need, and may help create more efficient and less polluting designs for burning fuel.

ACME’s Burning Rate Emulator (BRE) simulated the flammability of solid and liquid materials by burning gaseous fuels under specific conditions. Analysis of 59 BRE burn tests provided data on heat flow, flame size, effects of fuel mixture flow, and other important parameters.¹ Results could improve the fundamental understanding of materials flammability and assess whether existing methods for testing flammability are effective in microgravity.

Burning and Suppression of Solids (BASS) was one of the first investigations to examine how to extinguish fuels burning in microgravity. Putting out fires in space must consider flame geometry, characteristics of the materials, and methods used to extinguish it, because methods used on the ground could be ineffective or even make the flame worse.

BASS-II examined the characteristics of a variety of fuel samples to see whether materials burn as well in microgravity as in normal gravity, given the right conditions. Several papers have reported results from BASS-II, with findings including the differences between flame spread and fuel regression and comparison of flame spread rates.^2,3

SoFIE-GEL analyzes how the temperature of a fuel affects material flammability. Researchers report that experiment observations agree with trends predicted by the models. This investigation, the first in a series, tested various fuels including flat sheets, thick slabs, cylinders, and spheres.

Saffire is a series of experiments conducted aboard uncrewed Cygnus cargo spacecraft after they depart the station, which makes it possible to test larger fires without putting crew members at risk. Results on flame spread in microgravity can be used to establish the rate of heat release in a spacecraft⁴ and show that reducing pressure slows down that spread.⁵

Confined Combustion, sponsored by the ISS National Lab, examines flame spread in confined spaces of different shapes. Confinement affects fire characteristics and hazards. Researchers report specifics on interactions between a flame and its surrounding walls and the fate of the flame, such as growth or extinction.⁶ These results provide guidance for the design of structures, fire safety codes, and response in space and on Earth. Other results suggest that confinement can increase or decrease solid fuel flammability depending on conditions.⁷

FLARE, an investigation sponsored by JAXA (Japan Aerospace Exploration Agency), also tests the flammability of materials in microgravity. Results could significantly improve fire safety on future missions.

Flame studies help keep crews in space safe. This research also could lead to more efficient combustion that reduces pollutants and produces more efficient flames for uses on Earth such as heating and transportation.
