Rafael Navarro-González
Rafael Navarro-Gonzalez, also known as Rafael Navarro-González and Rafael Navarro, was a Mexican NASA astrobiologist who worked with the ''Curiosity'' rover on the planet Mars, and who helped lead researchers in the identification of ancient organic compounds on the planet. He was an internationally recognized scientist who merged laboratory simulations, field studies and modeling based on biology, chemistry and physics. Navarro-Gonzalez noted the significance of volcanic lightning in the origin of life on Earth. His professional work included the SAM component on the Mars Science Laboratory, and the HABIT instrument on the Exomars mission. He died from complications of COVID-19 on January 28, 2021. In April 2021, NASA named a mountain, "Rafael Navarro Mountain", on the planet Mars in his honor.

Sample Analysis At Mars
Sample Analysis at Mars (SAM) is a suite of instruments on the Mars Science Laboratory Curiosity (rover), ''Curiosity'' rover. The SAM instrument suite will analyze Organic compound, organics and gases from both atmospheric and solid samples. It was developed by the NASA Goddard Space Flight Center, the Laboratoire atmosphères, milieux, observations spatiales, Laboratoire des Atmosphères Milieux Observations Spatiales (LATMOS) associated to the Laboratoire Inter-Universitaire des Systèmes Atmosphériques (LISA) (jointly operated by France's Centre national de la recherche scientifique and Parisian universities), and Honeybee Robotics, along with many additional external partners. Instruments The SAM suite consists of three instruments: #The quadrupole mass analyzer, quadrupole mass spectrometer (QMS) detects gases sampled from the atmosphere or those released from solid samples by heating. #The gas chromatograph (GC) is used to separate out individual gases from a complex ...

ExoMars
ExoMars (Exobiology on Mars) is an astrobiology programme of the European Space Agency (ESA). The goals of ExoMars are to search for signs of past life on Mars, investigate how the Martian water and geochemical environment varies, investigate atmospheric trace gases and their sources and by doing so demonstrate the technologies for a future Mars sample-return mission. The first part of the programme is a mission launched in 2016 that placed the Trace Gas Orbiter into Mars orbit and released the ''Schiaparelli'' EDM lander. The orbiter is operational but the lander crashed on the planet's surface. The second part of the programme was planned to launch in July 2020, when the ''Kazachok'' lander would have delivered the ''Rosalind Franklin'' rover on the surface, supporting a science mission that was expected to last into 2022 or beyond. On 12 March 2020, it was announced that the second mission was being delayed to 2022 as a result of problems with the parachutes, which could ...

List Of Mountains On Mars By Height
This is a list of mountains on Mars by elevation, the vertical position relative to the areoid, which is the Martian vertical datum (the surface defined as zero elevation by average martian atmospheric pressure and planet radius). Elevation is ''not'' the height above the surrounding terrain (topographic prominence). *A mons (plural ''montes'') is a term used in astrogeology to name extraterrestrial mountains and may or may not be of volcanic origin. *A patera refers to the dish-shaped depression atop a volcano that is not very high compared to its diameter. *A tholus (pl. tholi) is the term used in astrogeology to describe a small domical mountain or hill. *Listed mons elevation is the highest point (at 16 pixels/degree) within the feature. *Listed patera elevation is the average elevation of the shallow dish-shaped depression (the actual 'patera') at the summit. Notable extreme elevations on Earth and Venus are included (in bold ''and'' ''Italics'') for comparison, where the giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The World Academy Of Sciences
The World Academy of Sciences (TWAS) is a merit-based science academy established for developing countries, uniting 1,000 scientists in some 70 countries. Its principal aim is to promote scientific capacity and excellence for sustainable development in developing countries. It was formerly known as the ''Third World Academy of Sciences''. Its headquarters is located on the premises of the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy. History TWAS was founded in 1983 under the leadership of the Nobel Laureate Abdus Salam of Pakistan by a group of distinguished scientists who were determined to do something about the dismal state of scientific research in developing countries. * Although developing countries account for 80% of the world's population, only 28% of the world's scientists hail from these countries. This fact reflects the lack of innovative potential necessary to solve real-life problems affecting poor nations. * A chronic lack o ...

Alexander Von Humboldt Medal
The International Association for Vegetation Science (IAVS) promotes contact between scientists and others interested in the study of vegetation ecology, promotes research and publication of research results. In 1939 the International Phytosociological Society (IPS) was founded, with its headquarters in Montpellier, France. After the Second World War it was reconstituted as the Internationale Vereinigung für Vegetationskunde (IVV), which adopted a constitution at the International Botanical Congress of 1954. The current name was adopted in 1981–82. Publications The society publishes: * '' IAVS Bulletin'' * '' Journal of Vegetation Science'' * '' Applied Vegetation Science'' * '' Resolutions'' Awards The Alexander von Humboldt Medal is a prize awarded biennially from 2011 onwards by the association. The award is intended to honor scientists who have contributed greatly to the intellectual development and advancement of vegetation science and plant community ecology. Honorary ...

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was COVID-19 pandemic in Hubei, identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, Anosmia, loss of smell, and Ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected Asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, Hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure ...
