In-flight calibration of the Ganymede Laser Altimeter (GALA) aboard Juice mission is important for measuring topography and tidal deformation of icy moons as well as surface reflectance. Using passive Earth observations, this study establishes a framework for receiver calibration in comparison with images. As a result, we report that GALA may have experienced a post-launch boresight offset over 700 μrad, together with the radiometric calibration for future reflectance measurements by GALA.

JANUS (Jovis, Amorum ac Natorum Undique Scrutator), the high-resolution camera on ESA’s JUICE (JUpiter ICy moons Explorer) mission, observed Earth during the August 2024 Lunar–Earth Gravity Assist. Images from a close flyby captured night- and day-side atmospheric phenomena, and a distant view resulted in a low-resolution Earth portrait. These observations validate JANUS performance and demonstrate the instrument’s capabilities. We focus our analysis on characterizing atmospheric systems that provide relevant examples for future studies of Jupiter’s atmosphere.

During a lunar flyby, the JANUS camera on board the Jupiter Icy Moons Explorer mission captured detailed images of the Moon’s surface. We studied a large impact crater and a nearby highland region, finding evidence of complex surface changes over time and signs of unusual volcanic activity. These results improve our understanding of how the Moon evolved and confirm that the JANUS camera is ready for future exploration of Jupiter’s moons.

JANUS is the high-resolution multispectral camera on board of the ESA JUICE mission. During 19-20 August 2024 JUICE flew by the Moon and the Earth performing a Lunar-Earth Gravity Assist maneuver that provided a unique opportunity to test the instruments in mission-like conditions. In this paper we describe the status of the calibration pipeline applied to JANUS data acquired, the lessons learned by the analysis of the calibrated data and the open points.

ESA's Jupiter Icy Moons Explorer (JUICE) spacecraft performed the first-ever Lunar–Earth Gravity Assist (LEGA) on 19–20 August 2024, executing a double flyby – first the Moon, then Earth – to gain a significant ΔV boost while conserving propellant. This paper describes this manoeuvre from trajectory design, navigation and spacecraft operations point of view.

We present an updated spectral and radiometric calibration of the Moons and Jupiter Imaging Spectrometer (MAJIS) aboard the Jupiter Icy Moons Explorer (JUICE), based on results of Earth and Moon observations in August 2024 and on observations of the MAJIS internal calibration unit. Very good agreements were obtained with results of other instruments and models. These MAJIS observations provide a promising teaser of what will be achieved by MAJIS in the system of Jupiter.

During its first Earth flyby, the JUpiter Icy Moons Explorer (Juice) spacecraft acquired observations over the Western Pacific. We identify several gaseous compounds (O2, H2O, CO2, O3, CH4, N2O), liquid/ice clouds over the ocean and atmospheric waves at high altitudes. We find good agreement with similar observations of Earth-orbiting PRISMA spectrometer. This study helps in planning future observations from the Moon and Jupiter Imaging Spectrometer (Majis) when it comes to the Jupiter system.

The first ever double gravity assist of Moon and Earth on the 19th and 20th of August 2024 by the ESA JUICE spacecraft provided a unique opportunity for payload calibration in preparation for the nominal science phase. Despite the complex set of constraints applicable to such operationally critical phases, the payload and facility instruments were able to operate. The excellent scientific dataset acquired confirmed the instrument performances.

Terrestrial lightning has been spectroscopically observed from Juice (JUpiter ICy moons Explorer) spacecraft, for the first time from space in a wide wavelength range. Though not detected by ground sensors, Juice confirmed neutral atomic oxygen and nitrogen emissions, with energies and temperatures consistent with average lightning. This observation is a benchmark for Jupiter, a primary Juice target, where simultaneous hydrogen emissions in different wavelengths could identify lightning.

This paper is the first in-flight geometric calibration of the MAJIS visible and infrared mapping spectrometer instrument onboard the ESA-Juice mission. It contains an overview of the spatial distribution of the MAJIS signal collected at different scan angles and their position in MAJIS field of view; the first two starfields in-flight calibration and multiple comparisons with the data collected by other Juice instruments during the first Lunar and Earth Gravity Assist (LEGA) by Juice in 2024.

During the double Lunar-Earth Gravitational Assist with the ESA/JUICE (Jupiter Icy Moons Explorer) spacecraft in August 2024, we acquired hyperspectral data cubes of both the Moon and Earth with the MAJIS (Moons And Jupiter Imaging Spectrometer) imaging spectrometer under challenging, real in-flight conditions. This allowed to characterize surface materials and thermophysical properties on the Moon, identify various cloud phases and gases in Earth's atmosphere, and thoroughly validate the performance of the instrument.

Short summary
This paper describes the observations of Moon and the Earth by the Jovis Amorum ac Natorum Undique Scrutator camera (JANUS) during Lunar Earth Gravity Assist (LEGA) in 2024 by the Jupiter Icy Moons Explorer (JUICE) spacecraft. We describe the observation sequences and constraints that were considered during the design process. We highlight the lessons learned from the relevant observational campaigns and the importance of science activities during the long cruise phase of planetary missions.
