Critical Level

1. A variable that has reached a sufficiently high or low value as to change the nature of what is discussed. For example, if the revenue of a small business reaches a certain level, it may need to hire additional employees, which could subject the business to more regulation, and this may result in the small business becoming a medium-sized business or even a large corporation. In this case, the revenue necessary to make this happen is called the critical level of revenue.

2. The time when a company's operations have become sufficiently profitable that it can sustain itself without further capital infusions or other sources of outside funding. Critical level is the goal of all start-ups, many of which may remain in the development stage for years or never leave it.

In both cases, the critical level is also called critical mass.

So, if the hot-particle-laden solar wind was the culprit in making the exosphere, the Japanese spacecraft SELENE should have seen a noticeable drop in the exosphere ions.

Moon's thin 'perfume' comes from the Sun!

However, scientists have been uncertain about which processes are the main contributors of lunar exosphere ions.

How the moon gets its exospehere

The GLIDE mission would study variability in Earth's exosphere, the uppermost region of its atmosphere, by tracking far ultraviolet light emitted from hydrogen.

NASA Selects Proposals to Further Study the Fundamental Nature of Space

When a stream of meteoroids rains down on the lunar surface, the liberated water will enter the exosphere and spread through it.

Meteorite strikes can eject water from moon: NASA

The mission orbited the Moon from October 2013 to April 2014 and gathered detailed information about the structure and composition of the lunar atmosphere, or more correctly, the "exosphere" -- a faint envelope of gases around the Moon.

Meteoroid Strikes Eject Precious Water from Moon

It also combines a thorough analysis of the data and a high-fidelity numerical modelling of the behaviour of water in the lunar exosphere.

Meteorite impacts release tonnes of water from the moon annually

The kids are invited to learn about large-scale topics ranging from what makes up the many layers of the Earth (from the core to exosphere) to the many neighboring planets and moons that comprise our Solar System.

Hey There, Earth Dweller!

Why, those dumb climate scientists, with all their relentless study of ice core samples, solar radiation, soil and water temperatures, fluctuating temperature variations in the earth's troposphere, stratosphere, mesosphere, thermosphere and exosphere, satellite imagery, trend analysis, etc., forgot about the ice ages.

Sure, dumb scientists forgot the ice ages

The 3,890-kg Chandrayaan-2 spacecraft, to be launched onboard the Geosynchronous Satellite Launch Vehicle (GSLV) Mk-3, will orbit around the moon to study its conditions and collect data of its topography, mineralogy and exosphere. After reaching the 100km lunar orbit, lander with rover will separate from the spacecraft and gradually descend to soft land on the moon at a designated spot.
