The Journal of Spacecraft and Rockets is a bi-monthly (six issues per year) peer-reviewed scientific journal published by the American Institute of Aeronautics and Astronautics. It covers the science and technology of spaceflight, satellite and mission design, missile design, and rockets.

Topics of interest for this journal are all interactions observed in space research, including space studies of the Earth's surface, meteorology, and climate. Acceptable articles in the context of space research are from the perspective of astrophysics, materials science, the life sciences, and fundamental physics. Also included in this context ...
An experiment in 2011 demonstrated OAM multiplexing of two incoherent radio signals over a distance of 442 m. [5] It has been claimed that OAM does not improve on what can be achieved with conventional linear-momentum based RF systems which already use MIMO, since theoretical work suggests that, at radio frequencies, conventional MIMO techniques can be shown to duplicate many of the linear ...
A space rendezvous is a sequence of orbital maneuvers during which two spacecraft, one of which is often a space station, arrive at the same orbit and approach to a very close distance (e.g. within visual contact).
A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
If the near-light-speed space craft is interacting with matter that is moving slowly in the planetary reference frame, this will cause drag which will bleed off a portion of the engine's acceleration. A second big issue facing ships using constant acceleration for interstellar travel is colliding with matter and radiation while en route.
The Space Report is the definitive overview of the global space industry and serves as a valuable resource for government and business leaders, educators, financial analysts, students, and space-relatedbusinesses. [1] Following are major findings from the 2013 issue. The global space economy grew to $304.31 billion in commercial revenue and ...
