In planetary geology, the term "ejecta" includes debris ejected during the formation of an impact crater. When an object massive enough hits another object with enough force, it creates a shockwave that spreads out from the impact. The object breaks and excavates into the ground and rock, at the same time spraying material known as impact ejecta.
When We Left Earth: The NASA Missions (or NASA's Greatest Missions: When We Left Earth in the UK) is a 2008 Discovery Channel HD documentary miniseries consisting of six episodes documenting American human spaceflight from the first Mercury flights and the Gemini program, to the Apollo program and its Moon missions and landings, to the Space Shuttle missions and the construction of the ...
[20] [2] The martian ejecta blankets are categorized broadly into three groups based on the observed morphology identified by spacecraft data: [14] a. Layer ejecta pattern: the ejecta blanket seems have formed by fluidization process and composed of single or multiple partial or complete layers of sheet of materials surrounding the crater. [ 14 ]
STEREO (Solar TErrestrial RElations Observatory) is a solar observation mission. [2] Two nearly identical spacecraft (STEREO-A, STEREO-B) were launched in 2006 into orbits around the Sun that cause them to respectively pull farther ahead of and fall gradually behind the Earth.
Earth tends to pull asteroids into partial or full orbits around it regularly before they are flung back out into space. For instance, one such space rock 2022 NX 1 was a short-lived “mini-moon ...
This causes their hold on their upper layers to weaken allowing small disturbances to blast large amounts of the outer layers into space. Events such as solar flares and coronal mass ejections are mere blips on the mass loss scale for low mass stars (like our sun). However, these same events cause catastrophic ejection of stellar material into ...
The Earth's plasma fountain, showing oxygen, helium, and hydrogen ions which gush into space from regions near the Earth's poles. The faint yellow area shown above the north pole represents gas lost from Earth into space; the green area is the aurora borealis—or plasma energy pouring back into the atmosphere. [1]
Three NASA astronauts and a Russian cosmonaut splashed to Earth early Friday, Oct. 25, after a nearly eight-month science mission at the International Space Station (ISS).
