Science fiction has featured characters wielding hand-held chemical scanning devices for years, but in the real world, that has hardly been the case—mass spectrometers and MRI machines are big and bulky, and not likely to be carted into the field for on-the-spot testing. But that may chan...
The smaller a droplet, the more surface area it has per unit mass; and we are spraying billions of tiny droplets per second. As the droplets fly through the vacuum of space, they radiate their heat away. But we are not through yet. The droplets continue through space for a moment, then...
Here, we describe the modeling of the ITS2 subcomplex, including five assembly factors Cic1, Nop7, Nop15, Nop53, and Rlp7, using a combination of cryo-electron microscopy and cross-linking of proteins coupled with mass spectrometry approaches. The resulting atomic models provide structural ...

Some embodiment of the utility model relates to an induction device, a torch assembly, an optical transmitting device, an atomic absorption device, and a mass spectrometer. In some embodiment, the induction device comprises a coil which is made of oxidation-resistant materials. In some other ...
This is because the spacecraft has to use part of its mass for propulsion, while the orbital fortress can use that mass allocation for more weapons instead. However orbital fortresses do have problems with heat radiators and supply. Supporting the fortresses, the planet's orbit will probably ...
One problem with this proposal is that it is less mass-efficient than conventional armor. When the particle is struck by the laser, it flashes to plasma, which then begins to disperse. The plasma initially blocks the laser beam, but as it disperses and the density drops, the laser beam ...
The trouble with glider wings is they really eat up your ship's mass budget, and are just dead weight for most of the mission. The deltaV limit is due to a couple of factors. The faster you shed deltaV, the more heat the heat shield will have to cope with, and there is a limit...
Space transport system from the game FTL: 2448 by Tri Tac Games A "linear accelerator" is a mass driver click for larger image Obviously an area where spacecraft land and blast off from is the sine qua non of a spaceport. Otherwise it isn't a spaceport at all. It doesn't matter if...
When Genghis Khan appeared, the Mongols, who had been ritual-taboo nomads were converted to Barbarians—and it was only the sheer overwhelming mass of geography that finally stopped them. Barbarism is one of the great breakthroughs in cultural evolution; for the first time, it establishes that...
