Exoatmospheric Kill Vehicle - Wikipedia
The Exoatmospheric Kill Vehicle (EKV) is the Raytheon-manufactured interceptor component with subcontractor Aerojet of the U.S. Ground-Based Midcourse Defense (GMD), part of the larger National Missile Defense system.
Exosphere - Wikipedia
In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere is the uppermost layer, where the atmosphere thins out and merges with outer space. It is located directly above the thermosphere. Very little is known about it due to a lack of research.
Exoatmospheric Kill Vehicle | Raytheon - RTX
The Exoatmospheric Kill Vehicle seeks out its target using multi-color sensors, a cutting-edge onboard computer and a rocket motor that helps it steer in space. EKV guides to the target and, with pinpoint precision, destroys the threat using nothing more …

To guard against stray matter that can cause problems in zero gravity, we produce our exoatmospheric kill vehicles in an extremely clean environment. It's known as the Space Factory in Tucson, Arizona, one of the few facilities of its kind in the United States.
The Exosphere - Center for Science Education
Although the exosphere is technically part of Earth's atmosphere, in many ways it is part of outer space. Consider that the average altitude of the International Space Station is about 330 km (205 miles), placing it in the thermosphere below the exosphere!

2019年6月28日 · “Exo” means outside and is the same prefix used to describe insects like grasshoppers that have a hard shell or “exoskeleton” on the outside of their body. The exosphere is the very edge of our atmosphere. This layer separates the rest of the atmosphere from outer space. It’s about 6,200 miles (10,000 kilometers) thick.
Exosphere | Thermosphere, Ionosphere & Magnetosphere
Exosphere, outermost region of a planet’s atmosphere, where molecular densities are low and the probability of collisions between molecules is very small. The base of the exosphere is called the critical level of escape because, in the absence of collisions, lighter, faster-moving atoms such as.
Exosphere Definition and Facts - ThoughtCo
2019年7月21日 · The exosphere is the outermost layer of the Earth's atmosphere, located above the thermosphere. It extends from about 600 km until it thins out to merge with interplanetary space. This makes the exosphere about 10,000 km or 6,200 miles thick or about as wide as the Earth. The top boundary of Earth's exosphere extends about halfway to the Moon.

2020年5月2日 · Exosphere, the final frontier. The exosphere is the layer of atmosphere farthest from Earth. The temperature in the exosphere rises when the Sun hits it with UV radiation. The word exosphere is two old Greek words combined: exo=outside, sphaira=sphere.
Exosphere - an overview | ScienceDirect Topics
The exosphere is defined as the outermost layer of Earth's atmosphere, starting from the exobase in the thermosphere and extending to space.
