Thinking food delivery platforms infrastructurally: The practices and politics of Baemin's infrastructuralisation in Seoul

New Technology, Work and Employment, EarlyView.
Abstract The proliferation of food delivery platforms is profoundly changing the way urbanites eat, work, and move. These platforms increasingly mobilise urban resources and population to function as critical infrastructure in the field of logistics and transportation, giving rise to a new form of governance.

Reviewing Martian Atmospheric Noble Gas Measurements: From Martian Meteorites to Mars Missions

Geosciences, 2020
Martian meteorites are the only samples from Mars available for extensive studies in laboratories on Earth. Among the various unresolved science questions, the question of the Martian atmospheric composition, distribution, and evolution over geological ...

The ISSI international study team on the martian PBL – status report and plan [PDF]

, 2008
Dynamical processes in the Martian boundary layer provide the means of communication between surface ice deposits and the free atmosphere, and the means of lifting dust from the surface.

Measurements of Forbush decreases at Mars: both by MSL on ground and by MAVEN in orbit

, 2017
The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) Curiosity rover, has been measuring ground level particle fluxes along with the radiation dose rate at the surface of Mars since August 2012. Similar to neutron monitors at

Thermal tides in the Martian middle atmosphere as seen by the Mars Climate Sounder [PDF]

, 2009
The first systematic observations of the middle atmosphere of Mars (35–80km) with the Mars Climate Sounder (MCS) show dramatic patterns of diurnal thermal variation, evident in retrievals of temperature and water ice opacity.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Morphology of the Excited Hydroxyl in the Martian Atmosphere: A Model Study—Where to Search for Airglow on Mars?

Remote Sensing
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere.

Hubble Space Telescope observations of Mars [PDF]

Hubble Space Telescope (HST) afforded the possibility of resolving features as small as 100 km on the Martian surface even when it is at the far point of its orbit. Therefore it is ideally suited for monitoring seasonal changes on the red planet.
