O.o yayyyyyyyyyyyyy.

When it comes to space, there’s a problem with our human drive to go all the places and see all the things. A big problem. It’s, well, space. It’s way too big. Even travelling at the maximum speed the Universe allows, it would take us years to reach our nearest neighbouring star.

But another human drive is finding solutions to big problems. And that’s what NASA engineer David Burns has been doing in his spare time. He’s produced an engine concept that, he says, could theoretically accelerate to 99 percent of the speed of light — all without using propellant.

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.

This man lived inside a self-sustaining glass biosphere for 2 whole years to test drive what life would be like for humans on Mars via NowThis.

SpaceX CEO Elon Musk says humanity needs a “whole new architecture” to fly in space beyond low Earth orbit.

SpaceX CEO Elon Musk explains why we need a ‘whole new architecture’ for space travel :

Despite the lack of official comment on the mission, China’s first expedition to Mars appears to be on track.

In a new video, aerospace company Blue Origin reveals its finished mission control center in Cape Canaveral, Florida, where engineers will monitor upcoming launches of the company’s future New Glenn rocket. The rocket is expected to fly sometime in 2021.

He also mentions the large sum of cash he can make from Starlink.

(Bloomberg) — An exhausted-looking Elon Musk said Monday he’s unsure his rocket company SpaceX will accomplish its foundational mission — getting to Mars — before he dies.

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.

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.”

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.
