SpaceX Starship Recommendations and SN 11 Crash

A propellant-free superconducting solenoid thruster driven by geomagnetic field

Space travel nowadays relies on physical ejection of propellants, which is challenged by reachable distance of a vehicle in desirable time. In contrast, electromagnetic propulsion was proposed to be a potential solution without need of carrying bulky mass of propellants, by using force interaction of local magnetic dipoles with the external natural magnetic field. Further development of this technique, however, has been daunted by extremely small magnetic induction that can be obtained.

To generate a significant thrust by a system with a reasonable scale, we propose an alternative concept of design, based on the variation of local magnetic dipole moments that has not been considered.

A magnetic dipole is created by wrapping a solenoid around an iron core. It is varied spatially by changing the cross-sectional area of the solenoid, hence giving a gradient of magnetic dipole moment. The interaction force is measured by an in-house force sensor based on a cantilever, which has a high sensitivity of one micro-Newton. In addition, numerical simulation is used to calculate the magnetic field and created force via the Maxwell stress tensor.

SpaceX’s Dragon spaceship is getting the ultimate window for private Inspiration4 spaceflight

It’s a glass dome with a view.

When SpaceX launches four civilian astronauts on the private Inspiration4 spaceflight, they’re going to have the ultimate window: a glass dome offering panoramic views of Earth from space.

While SpaceX’s Crew Dragon spacecraft for the mission is already equipped with flat windows, the Inspiration4 mission — which is set to launch later this year with billionaire Jared Isaacman, who chartered the flight with SpaceX, commanding the crew — will include a unique domed window, allowing crew members to get a 360-degree view of their surroundings. That new window, and the Inspiration4 mission’s full crew, were announced in a press conference today (March 30).

Congress raises concerns about FAA’s handling of Starship launch license violation

WASHINGTON — As SpaceX gears up for another test flight of a Starship prototype, the Federal Aviation Administration is facing new scrutiny from Congress for how it handled SpaceX’s violation of its launch license on an earlier test flight.

SpaceX had planned to launch its SN11 Starship vehicle March 29 from its Boca Chica, Texas, test site. That flight will be similar to those of previous Starship prototypes, going to an altitude of 10 kilometers before landing on a nearby pad.

However, SpaceX called off the March 29 launch attempt because an FAA inspector could not arrive to observe the flight during a five-hour window. “FAA inspector unable to reach Starbase in time for launch today,” tweeted Elon Musk, chief executive of SpaceX, using the proposed new name for the Boca Chica site. “Postponed to no earlier than tomorrow.”

See the Astonishing Plans for the Very First City on Mars

A one-way ticket (including a cliffside condo!) starts at $300000.

An architecture firm has released ambitious plans for Nüwa, a sustainable city on Mars that could hold up to 250000 people in mostly underground cave systems.

Nüwa, named for the Chinese mythological goddess who melted five stones to give robust societal pillars, would be housed inside a sheer rock face where residents would be protected from damaging cosmic and solar radiation.

If you decide to move to Mars, your $300000 ticket will include a one-way trip to Nüwa, a residential unit of 25 to 35 square meters, full access to facilities, life support services and food, and “a binding work contract to devote between 60 [percent] and 80 [percent] of [your] work time to tasks assigned by the city,” according to ABIBOO, the architecture studio behind the concept.
