A vision of a future Moon base that could be produced and maintained using 3D printing [1] Crystals grown by American scientists on the Russian Space Station Mir in 1995: (a) rhombohedral canavalin, (b) creatine kinase, (c) lysozyme, (d) beef catalase, (e) porcine alpha amylase, (f) fungal catalase, (g) myglobin, (h) concanavalin B, (i) thaumatin, (j) apoferritin, (k) satellite tobacco mosaic ...
A time crystal can be informally defined as a time-periodic self-organizing structure. While an ordinary crystal is periodic (has a repeating structure) in space, a time crystal has a repeating structure in time. A time crystal is periodic in time in the same sense that the pendulum in a pendulum-driven clock is periodic in time.
[1] [2] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. [3] Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
Shackleton Energy Company: propellant, space infrastructure, propellant depot: Unknown Defunct (2020) [228] Made In Space: 3D printing in ISS, in-space antenna systems, fiber optics Unknown Operational (2018) [229] Varda Space Industries: building products in space and bringing them back to earth (ex: ZBLAN, 3d printed organs) Unknown ...
A high-energy beam of deuterium ions generated by pyroelectric crystals was directed at a stationary, room-temperature ErD 2 or ErT 2 target, and fusion was observed. [2] In previous fusion research, such as inertial confinement fusion (ICF), fuel such as the rarer tritium is subjected to high pressure for a nano-second interval, triggering fusion.
According to Lew Allen, the initial key design elements were specified by Edwin H. Land.They included i) solid state focal plane array, ii) integrated circuits for complex data processing, iii) large, fast optics with a 2.54 m (100 in) diameter f/2 primary mirror, iv) gigabit/s data link, v) long on-orbit operational lifetime for the imaging satellites, and vi) communication satellites to ...

Lunar materials could facilitate continued exploration of the Moon, facilitate scientific and economic activity in the vicinity of both Earth and Moon (so-called cislunar space), or they could be imported to the Earth's surface where they would contribute directly to the global economy. [1]
