A conventional power station would be able to meet those power demands, but it is far too large to put into orbit. So far, scientists have not been able to develop a suitable lightweight power source that can meet those power demands. The X-33 space plane may be used for military ...
Image Courtesy: MDA The LRDR has a large field of view over large sections of the Pacific theater and is said to be able to track multiple small objects in addition to"all classes of ballistic missiles, at very long ranges, under continuous operation."According to the MDA's press release,...
The rockets take astronauts and man-made satellites into space. The satellites are used for communication weather monitoring and research. But how do satellites stay up without falling down? There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (...
Space Force is working to tackle it. (Image credit: Karl Tate) Space may seem nearly endless, but our orbit is finite. With no international laws in place to clean up debris, the responsibility must be shared. The U.S. Space Force is doing their part by stepping up and working to ...

I am trying to control SingleArmManipulator using the task-space force controller. To do so, I need to get the force/torque that is applied to the end-effector, but the SingleArmManipulatorData does not provide an API to get this information. Is there a way to get force/torque? I foun...
US President Donald Trump’s mooted Space Force, which he suggested will be a “separate but equal” branch of the military, is vital to maintaining a tactical advantage over geopolitical adversaries, according to analysts and members of the US military.
