Expedition 56
Expedition 56 was the 56th expedition to the International Space Station, which began on June 3, 2018, upon the departure of Soyuz MS-07. Andrew Feustel, Oleg Artemyev, and Richard R. Arnold were transferred from Expedition 55, with Andrew Feustel taking the commander role. Alexander Gerst, Serena M. Auñón-Chancellor, and Sergey Prokopyev (cosmonaut), Sergey Prokopyev launched aboard Soyuz MS-09, on June 6, 2018. Expedition 56 ended with the departure of Soyuz MS-08 on October 4, 2018. Crew Originally NASA Astronaut Jeanette Epps was assigned as flight engineer for Expeditions 56 and 57, becoming the first African American space station crew member and the 15th African American to fly in space, but on January 16, 2018, NASA announced that Epps had been replaced by her backup Serena M.

Expedition 57
Expedition 57 was the 57th expedition to the International Space Station, which began on October 4, 2018, upon the departure of Soyuz MS-08. History Soyuz MS-09 crew, Alexander Gerst, Serena M. Auñón-Chancellor, and Sergey Prokopyev, since June 2018 aboard the ISS, were expected to be joined by Aleksey Ovchinin and Nick Hague in October 2018. The latter two crew members boarded Soyuz MS-10 on October 11, 2018, but the launch was aborted mid-flight due to a booster failure; the crew landed safely after a ballistic descent. The impact of the Soyuz MS-10 failure and subsequent investigation on the ISS crew schedule was not initially clear. The Expedition 57 initial crew needed to depart by mid-December 2018 in Soyuz MS-09 due to the limited on-orbit lifespan of "about 200 days" of the Soyuz capsule, or no later than early January 2019 allowing for a small margin on the lifespan. NASA would have attempted to avoid de-crewing the ISS, commanding the station from the ground is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ESA CAVES
CAVES, an acronym for Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills, is a European Space Agency astronaut training course in which international astronauts train in a space-analogue cave environment. Designed at the European Astronaut Center, the course aims to prepare astronauts for safe and efficient long duration spaceflight operations by means of a realistic scientific and exploration mission within a multicultural, ISS-representative team. Each training course lasts for approximately three weeks. The first two weeks focus on providing the astronauts with the necessary behavioural patterns, scientific knowledge, and technical skills to work effectively and safely in an underground environment. During this time, trainees visit simple caves to become acquainted with the conditions they will find themselves in during their final expedition, a six-day uninterrupted expedition exploring a complex cave system. The main purpose of the missio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Erebus
Mount Erebus () is the second-highest volcano in Antarctica (after Mount Sidley), the highest active volcano in Antarctica, and the southernmost active volcano on Earth. It is the sixth-highest ultra mountain on the continent. With a summit elevation of , it is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. The volcano has been active since about 1.3 million years ago and has a long-lived lava lake in its inner summit crater that has been present since at least the early 1970s. The volcano was the site of the Air New Zealand Flight 901 accident, which occurred in November 1979. Geology and volcanology Mount Erebus is the world's southernmost active volcano. It is the current eruptive centre of the Erebus hotspot. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting lava lakes on Earth.

Types Of Volcanic Eruptions
Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions: * Magmatic eruptions are the most well-observed type of eruption. They involve the decompression of gas within magma that propels it forward. * Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. * Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic erup ...
