Space technology is technology for use in outer space. Space technology includes space vehicles such as spacecraft , satellites , space stations and orbital launch vehicles ; deep-space communication ; in-space propulsion ; and a wide variety of other technologies including support infrastructure equipment, and procedures .
A little later in the same year Albert Einstein published his original paper on special relativity in which, again based on the relativity principle, he independently derived and radically reinterpreted the Lorentz transformations by changing the fundamental definitions of space and time intervals, while abandoning the absolute simultaneity of ...
SpaceX also needed a test site for the Merlin and Kestrel engines. In 2002, the company rented a space at the Mojave Air and Space Port to test the turbopumps, but soon SpaceX ran into issues with the testing facility: one time, black sooty clouds from the turbopump enveloped the air traffic control tower. A bigger and more lax testing facility ...
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1] [1] [2]
21 May 2023 – Axiom Mission 2 marks the first time a commercially operated crewed mission was used to fly government astronauts as well as being the first private mission with a female commander. 14 September 2023 – Firefly Aerospace conducts a successful orbital launch with the VICTUS NOX mission for the U.S. Space Force Space Systems ...
Recent space exploration has proceeded, to some extent in worldwide cooperation, the high point of which was the construction and operation of the International Space Station (ISS). At the same time, the international space race between smaller space powers since the end of the 20th century can be considered the foundation and expansion of ...
America Online CEO Stephen M. Case, left, and Time Warner CEO Gerald M. Levin listen to senators' opening statements during a hearing before the Senate Judiciary Committee on the merger of the two ...
This constant would restore to the general theory's description of space-time an invariant metric tensor for the fabric of space/existence. The first person to seriously apply general relativity to cosmology without the stabilizing cosmological constant was Alexander Friedmann. Friedmann derived the expanding-universe solution to general ...
