Helmholtz decomposition

Posted by in categories: physics, space travel

Essentially this can lead to euclidean geometry in programming essentially allowing near infinite decompression either in programming or in devices or even spaceships.


In physics and mathematics, in the area of vector calculus, Helmholtz’s theorem,[1][2] also known as the fundamental theorem of vector calculus,[3][4][5][6][7][8][9] states that any sufficiently smooth, rapidly decaying vector field in three dimensions can be resolved into the sum of an irrotational (curl-free) vector field and a solenoidal (divergence-free) vector field; this is known as the Helmholtz decomposition or Helmholtz representation. It is named after Hermann von Helmholtz.[10]

As an irrotational vector field has a scalar potential and a solenoidal vector field has a vector potential, the Helmholtz decomposition states that a vector field (satisfying appropriate smoothness and decay conditions) can be decomposed as the sum of the form − ∇ ϕ + ∇ × A {\displaystyle -\nabla \phi +\nabla \times \mathbf {A} }, where ϕ {\displaystyle \phi } is a scalar field called “scalar potential”, and A is a vector field, called a vector potential.

SpaceX’s latest Starship prototype passes big tank pressure test

Posted by in categories: Elon Musk, space travel

SpaceX’s newest prototype of its Starship Mars-colonizing vehicle just passed a crucial pressure test, potentially paving the way for more ambitious trials in the near future.

Starship version SN2 survived a cryogenic pressure test late Sunday (March 8) at SpaceX’s South Texas facilities, company founder and CEO Elon Musk said. You can see a video timelapse of the test from Starship watcher Mary BocaChicaGal here for NASASpaceflight.com.

SpaceX Makes History With 50th Rocket Landing

Posted by in category: space travel

CAPE CANAVERAL (CBSMiami/AP) — SpaceX made history this weekend when it successfully landed its 50th rocket after launching another load of station supplies for NASA.

The Falcon rocket blasted off with 4,300 pounds (1,950 kilograms) of equipment and experiments for the International Space Station. Just minutes later, the spent first-stage booster made a dramatic midnight landing back at Cape Canaveral, its return accompanied by sonic booms.

“And the Falcon has landed for the 50th time in SpaceX history!” SpaceX engineer Jessica Anderson announced amid cheers at Mission Control. “What an amazing live view all the way to touchdown.”

Astronauts capture SpaceX cargo capsule with robot arm for final time

Posted by in categories: robotics/AI, space travel

For the final time, a SpaceX Dragon cargo capsule approached the International Space Station Monday for capture with the research lab’s robotic arm, delivering more than 4,300 pounds of food, experiments and spare parts. Future Dragon resupply missions will use a new spaceship design to automatically dock with the space station.

The unpiloted cargo freighter completed a two-day pursuit of the space station Monday with an automated approach to the orbiting research outpost.

After moving into position less than 40 feet (12 meters) below the station, the Dragon capsule halted its approach and astronaut Jessica Meir took control of the research lab’s Canadian-built robotic arm. Meir, assisted by crewmate Drew Morgan, captured the Dragon spacecraft at 6:25 a.m. EDT (1025 GMT) Monday, more than a half-hour ahead of schedule.
