New rocket engine designs can improve spaceflight.

The rotating detonation rocket engine (RDE) could be the new thruster for space missions. These engines use a rotating combustion event to generate more thrust. That is why the RDE engines are under development. Those engines could serve regular space rockets. And maybe trans-atmospheric planes (TAV). Those are so-called rocket planes. The TAV vehicle can operate from regular runways. Travel in the atmosphere using regular jet engines. 

And when they must operate outside the atmosphere, those planes switch to rocket engines. These tools are required for next-generation orbital operations. The original TAV system concept uses air-breathing engines to reach trans-atmospheric orbit (TAO). There. The improved version can activate its rocket engines. 

Another remarkable tool. They are the so-called Hall-effect engines. Those engines use ion flow to give thrust. The problem with those engines is their weak thrust. But their specific impulse is very high. Hall-effect engines use recoil from ions. To move the craft forward. And the big problem is the thrust. Hall-effect thrusters require. A regular rocket. To lift off from the atmosphere.

“Hall thruster. Hall thrusters are largely axially symmetric. This is a cross-section containing that axis.” (Wikipedia, Hall-effect thruster)

“Nuclear-powered spacecraft (render)” (Interesting engineering) 

The new Hall-effect thruster, named Starlight, uses solid zinc as propellant. Those systems could also use mercury, iron, or any other ionized material as propellants. 

Maybe. It's possible. To create electromagnetic-chemical rocket engines. That also creates strong thrust. There is a possibility. To expand propellant in the combustion chamber using a laser or microwave system. The propellant will be conducted into the combustion or expansion chamber. And then lasers or microwaves expand that propellant, which can be hydrogen. 

There is also the possibility of creating an ion system. That ionizes air at the front of the wing. And then magnetic rails pull those ions from above the wing. This kind of system. It can decrease the aircraft's weight. The aircraft doesn’t need to move if it levitates. The system. It must just make gas. To flow over the top of the wing. That air, or ion flow, can also decrease the ground pressure. And if that flow is strong enough. That system can pull the aircraft into the air.  Ion systems can also act as plasma stealth. That makes aircraft invisible to radar. 

An ion cannon that launches an ion beam in the atmosphere can create an extremely strong flash. That gives those systems a stun effect. 

The interplanetary spacecraft requires nuclear reactors. Those systems create electric arcs for thrusters. That vaporizes propellant. The new Hall-effect thruster used solid zinc as propellant. That kind of thruster can open a path to the entire solar system. But the fact is that. The Hall-effect thrusters are easy to transform into space weapons. The system can shoot anions in the middle of the ion beams. Or the electron beam. The electron beam. That travels in the ion beam. Can keep those beams in their form. Those high-energy systems require nuclear reactors.

German startup launched a rocket from Norway.

German startup Isar Aerospace made history. It launched the Spectrum rocket into orbit from Norway. The launch was made from the Andøya spaceport. And it's the first orbital launch from the European continent. This is a remarkable step. 

The Spectrum rocket is Isar Aerospace’s two-stage launch vehicle, 28 m tall and 2 m in diameter, and has ten engines. It is meant to launch payloads of up to 1000 kg to low Earth orbit. The Spectrum rocket carried five CubeSats and one scientific experiment. That kind of system is ideal for high-atmosphere research. And. Launching low-orbiting reconnaissance satellites.  If Europe wants space independence. It also needs ASAT systems. That can protect and affect hostile satellites. 

These kinds of systems. They are quite similar to Russian/Ukrainian Tsyklon rockets. But Tsyklon is heavier. It can transport 4000 kg to low Earth orbit. The Spectrum type of rocket increases European space independence. Those light/medium systems can launch European reconnaissance satellites. The biggest problem is that Europe needs space independence. European northern areas are excellent places. To launch satellites into polar trajectories. This is why Elon Musk wants Greenland.  Another possibility is to launch rockets from ships. 

Light. Or medium boosters can be transported to the launch area by ships. And then the launch can be made from a ship.  During this process, the crew can wait on another ship. Until. The rocket leaves. The launch procedure can be performed. Using AI-controlled computers under remote control. 

The reason for that is safety. There is always a small possibility that the rocket explodes. Another thing is the noise. Rockets are noisier than aircraft. So the launching units must wait at a safe distance. Or the launching crew must stay in rooms with special sound isolation. The vacuum layer between outside and safe rooms can make launching safer. 

The Spectrum rocket. Before launch. 

One reason nations are interested in Northern areas is that it is easiest to send satellites into polar trajectories. High-resolution reconnaissance satellites use this trajectory. When a satellite reaches the polar cap, it changes its course. Then it can get the best possible coverage of Earth for its sensors. This is one of the reasons. That makes northern areas interesting. 

Another place with the same benefits for satellite launching is Antarctica. The problem is that Antarctica is very far away from Europe. And North America. Many spaceports are near the equator. There. Earth's rotation pushes rockets forward.  This is why almost all rockets travel in the same direction as the Earth’s rotation. Israel is an exception. It launches rockets in a different direction. There, they don't fly over Arab nations. The equatorial orbit is ideal for communication satellites. But reconnaissance satellites use polar trajectories to cover larger land areas. Military launches highly classified satellites. 

It sets its own limits for the trajectories.  Satellites travel over the sea as much as possible during the booster stage. If the booster fails, the satellite drops into the sea. And hostile countries will not get its components into their hands. A launch from Norway is a pathfinder for a new, more independent Europe. Media all around the world noticed that launch. Reuters. And Al Jazeera and many other news agencies gave it media space.
