Solar One (interstellar)
Solar One is a proposed spacecraft A spacecraft is a vehicle that is designed spaceflight, to fly and operate in outer space.

The spacecraft would include a light sail, a laser system, a Bussard scoop, and a compact nuclear fusion reactor. Large mirrors would be assembled in orbit and sent close to the Sun to collect sufficient light to propel the light sail. The on board laser would help the Bussard scoop collect hydrogen to power the nuclear reactor which, in turn, would power both the laser and the electromagnetic scoop to decelerate the spacecraft. The main challenges are building large parabolic mirrors as well as reducing the weight of the on board laser system and compact nuclear reactor. References {{Reflist Hyp ...

__NOTOC__ Year 341 ( CCCXLI) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Marcellinus and Probinus (or, less frequently, year 1094 ''ab Urbe condita''). The denomination 341 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years or dates.

Spacecraft
A spacecraft is a vehicle that is designed spaceflight, to fly and operate in outer space. Spacecraft are used for a variety of purposes, including Telecommunications, communications, Earth observation satellite, Earth observation, Weather satellite, meteorology, navigation, space colonization, Planetary science, planetary exploration, and Space transport, transportation of Human spaceflight, humans and cargo spacecraft, cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Geocentric orbit, Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other Astronomical object, celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
