In orbit, a spacecraft with one axis much longer than the other two will spontaneously orient so that its long axis points at the planet's center of mass. This system has the virtue of needing no active control system or expenditure of fuel. The effect is caused by a tidal force. The upper end of the vehicle feels less gravitational pull than ...
A 2022 concept by MIT Senseable City Lab proposes using thin-film structures ("space bubbles") manufactured in outer space to solve the problem of launching the required mass to space. [18] MIT scientists led by Carlo Ratti believe deflecting 1.8 percent of solar radiation can fully reverse climate change.
Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]
The computer was architecturally similar to the Saturn Launch Vehicle Digital Computer, in particular in the instruction set; [6] however its circuit integration was less advanced. [7] The GGC weighed 58.98 pounds (26.75 kg) and was powered by 28V DC. During a short power outage it could be powered by the Auxiliary Computer Power Unit (ACPU)
TRACE is a high-precision orbit determination and orbit propagation program. It was developed by The Aerospace Corporation in El Segundo, California. An early version ran on the IBM 7090 computer in 1964. [1] The Fortran source code can be compiled for any platform with a Fortran compiler.
As of 2012 there were an estimated 500,000 pieces of debris in orbit, [4] with 300,000 pieces below 2000 km . [1] Of the total, about 20,000 are tracked. [ 1 ] Also, about sixteen old Soviet nuclear space reactors are known to have released an estimated 100,000 NaK liquid metal coolant droplets 800–900 km up, [ 5 ] which range in size from 1 ...
Pioneer 6, 7, 8, and 9 were space probes in the Pioneer program, launched between 1965 and 1969. They were a series of solar-orbiting, spin-stabilized, solar cell- and battery-powered satellites designed to obtain measurements on a continuing basis of interplanetary phenomena from widely separated points in space.

Vandenberg Space Launch Complex 6 (SLC-6, pronounced "Slick Six") is a launch pad and associated support infrastructure at Vandenberg Space Force Base in California. Construction at the site began in 1966, but the first launch didn't occur until 1995 due to program cancellations and subsequent repurposing efforts.
