Deep Space Network (DSN) currently consists of three deep-space communications facilities placed approximately 120 degrees apart around the Earth. They are: the Goldstone Deep Space Communications Complex (35°25′36″N 116°53′24″W) outside Barstow, California. For details of Goldstone’s contribution to the early days of space probe tracking. ...

Clustered Regularly Interspaced Short Palindromic Repeats Repetitive DNA sequences, called CRISPR, were observed in bacteria with spacer DNA sequences in between the repeats that exactly match viral sequences. It was subsequently discovered that bacteria transcribe these DNA elements to RNA upon viral infection. The RNA guides a nuclease (a pro...

A private jet, business jet, or bizjet is a jet aircraft designed for transporting small groups of people. Business jets may be adapted for other roles, such as the evacuation of casualties or express parcel deliveries, and some are used by public bodies, government officials or the armed forces. Most production business jets use two jet engine...

A spaceship is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spaceship except single-stage-to-orbit vehi...

Jet engines, which are also called gas turbines, work by sucking air into the front of the engine using a fan. From there, the engine compresses the air, mixes fuel with it, ignites the fuel/air mixture, and shoots it out the back of the engine, creating thrust. A turbofan engine, sometimes referred to as a fanjet or bypass engine, is a jet eng...

In physics and relativity, Time Dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them (“kinetic” time dilation, from special relativity) or to a difference in gravitational potential between their locations (gravitational time dilation, from general relativity). When unspec...

MarsLink.in 2024, Landing Five starships land on Mars, marking the beginnings of the Mars colony. All of the martian rovers sent by different countries before this day. Watch as the five uncrewed starships land and deliver life support systems, these pioneering starships pave the way for humans to land on Mars in two years time, for fishes t...

The butterfly effect is the idea that small, seemingly trivial events may ultimately result in something with much larger consequences – in other words, they have non-linear impacts on very complex systems. For instance, when a butterfly flaps its wings in India, that tiny change in air pressure could eventually cause a tornado in Iowa. The ter...
