  2. Batteries in space - Wikipedia

    en.wikipedia.org/wiki/Batteries_in_space

    Batteries are used on spacecraft as a means of power storage. Primary batteries contain all their usable energy when assembled and can only be discharged. Secondary batteries can be recharged from some other energy source, such as solar panels or radioisotope-based power (), and can deliver power during periods when the space vehicle is out of direct sunlight.

  3. Black hole starship - Wikipedia

    en.wikipedia.org/wiki/Black_hole_starship

    Black holes seem to have a sweet spot in terms of size, power and lifespan which is almost ideal. A black hole weighing 606,000 metric tons (6.06 × 10 8 kg) would have a Schwarzschild radius of 0.9 attometers (0.9 × 10 –18 m, or 9 × 10 –19 m), a power output of 160 petawatts (160 × 10 15 W, or 1.6 × 10 17 W), and a 3.5-year lifespan ...

    This is a list of spacecraft powered by non-rechargeable batteries.While most spacecraft are powered by longer-lasting power sources such as solar cells or radioisotope thermoelectric generators, which can provide power for years to decades, some have been powered by primary (non-rechargeable) electrochemical cells, which provide runtimes of minutes to months.

  7. Halo Drive - Wikipedia

    en.wikipedia.org/wiki/Halo_Drive

    A spacecraft using the halo drive would be capable of accelerating to 133% of the speed of the black hole. This is true regardless of the mass of the spacecraft, so long as it is significantly less than the mass of the black hole. This means that the acceleration of very large spacecraft to relativistic speeds becomes feasible. [1] [2]

    However, the merger of black holes is expected to occur during the collision of galaxies. [8] This unsolved problem is known as the final parsec problem. By finding and studying black holes less than 1 pc apart, ORBIS aims to resolve this issue. [8] Computer simulation of a binary black hole system

  9. Field propulsion - Wikipedia

    en.wikipedia.org/wiki/Field_propulsion

    Field propulsion is the concept of spacecraft propulsion where no propellant is necessary but instead momentum of the spacecraft is changed by an interaction of the spacecraft with external force fields, such as gravitational and magnetic fields from stars and planets.
