Astronomy & Geophysics, 2009 In June 2009 a community workshop discussed what priorities in landing-site selection would drive UK involvement in Mars lander missions. The organizers and participants (below) summarize the conclusions of the workshop and their overview of current and future priorities in the UK search for signs of life on Mars.

Mars Exploration Using Sailplanes
Aerospace, 2022 We present the preliminary design of sailplanes, used for Mars exploration. The sailplanes mitigate the weight and energy storage limitations traditionally associated with powered flight by instead exploiting atmospheric wind gradients for dynamic ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
FEBS Letters, EarlyView.This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Insights of the Qualified ExoMars Laser and Mechanical Considerations of Its Assembly Process
Instruments, 2019 1960 is the birth year of both the laser and the Mars exploration missions. Eleven years passed before the first successful landing on Mars, and another six before the first rover could explore the planet’s surface.

Mars Exploration Rovers Landing Dispersion Analysis [PDF]
AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 2004 Landing dispersion estimates for the Mars Exploration Rover missions were key elements in the site targeting process and in the evaluation of landing risk. This paper addresses the process and results of the landing dispersion analyses performed for both Spirit and Opportunity. The several contributors to landing dispersions (navigation and atmospheric
