As opposed to temperature and rainfall changes that leave their imprint in sedimentary layers, tree rings, or ice cores, clouds have the ability to dissipate quickly – and when this happens, computer simulations indicate that climate tipping points could result in 8 additional degrees of warming globally over the course of one century – this

Aerospace engineers design and test aircraft, spacecraft, satellites and missiles according to the Bureau of Labor Statistics. In addition, they may oversee manufacturing of these products and systems. Astronautical engineers design and construct spacecraft, the vehicles astronauts use to explore what remains mostly uncharted areas of space. This work can be both challenging and rewarding.

Every few weeks this year, astrological Mercury will appear to move retrogradely in the sky. Mercury governs communication, clear thinking and travel; when retrograded it can cause miscommunication and tech malfunctions that negatively impact daily life. As a general guideline, try not to enter into any major agreements or sign any new contracts during this

An IMU (Inertial Measurement Unit) is a sensor that measures body-frame acceleration and angular rate measurements. IMUs are often integrated into Inertial Navigation Systems (INSs) used to track spacecraft position. IMU sensors can experience both static and dynamic errors that could impede performance. Attitude As the spacecraft rotates in orbit, its attitude must be determined.
