The Videosphere is a JVC CRT television that was shaped in the form of a space helmet. It was first introduced in 1970 and was sold up until the early 1980s. It was popular for its modern design; the alarm clock base was an option, most units have a plain base. Videospheres were produced in large quantities in white, red, black, orange and grey.
This is a timeline of known spaceflights, both crewed and uncrewed, sorted chronologically by launch date. Due to its large size, the timeline has been split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951.
Das Problem der Befahrung des Weltraums – der Raketen-Motor (The Problem of Space Travel – The Rocket Motor) discusses space travel and its potential uses for scientific experiments. Germany Herman Potočnik: January 1933: British Interplanetary Society founded. UK Philip E. Cleator April 1933: First detection of radio waves from an ...
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. [7] For example, a rocket that accelerated at standard acceleration due to gravity toward the Andromeda Galaxy and started to decelerate halfway through the trip would arrive in about 28 years, from the frame of reference of the observer.
The weight savings, from reduced size as well as decreased instrumentation in the early satellites, was considered to be acceptable. As Vanguard 1, Vanguard 2 , and Vanguard 3 are still orbiting with their drag properties essentially unchanged, they form a baseline data set on the atmosphere of Earth that is over 60 years old and continuing.
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
"Look at how fast everyone warmed up to 'fascist dictator' Donald Trump. Not even Dr. Jill Biden can resist this world class charmer," one commenter mused.
This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
