Space engines according to need

What we need are new technologies and new materials without We want to develop more powerful and efficient space engines, what can be seen in the image below is a solar electric thruster that emits the blue tone of senon gas during the tests that were carried out inside a vacuum chamber at the Glenn Research Center of the NASA in Cleveland. It is a 12 kW Hall thruster, it is the most powerful built and will be essential for future scientific exploration missions on the moon and beyond. What these electric propulsion systems do is gradually accelerate the spacecraft until they reach extremely high speeds. high, using only a fraction of the fuel required by typical chemical propulsion systems.

Fuel rockets are still used because they provide great power and quickly, in other words, if you need to take off from the earth, the moon or Mars today you will have to use a chemical propulsion rocket, because you need power and quickly to overcome the force of gravity, but once in space, electric propulsion motors are ideal because with very little energy consumption they provide you with thrust that accumulates over time until reaching enormous speeds, which is why they are ideal for scientific missions. and deep space exploration. This engine will be mounted on the lunar space station of the Artemis program led by NASA.

Another engine that is being developed as an alternative is that of the Spanish company Pangea Aerospace, it has successfully completed a new phase of testing of various components and subsystems of its aerospike engine, it is a Spanish company, this engine is going to revolutionize the way of accessing to space, it is an engine that runs on biomethane and liquid oxygen, is efficient, sustainable and reusable. Biomethane is very interesting, it is also known as renewable gas, it is a fuel gas that is obtained from biogas after subjecting the latter to a treatment and biogas is produced from the decomposition of organic remains such as agricultural waste, excrement or sewage sludge. This engine is not only efficient and sustainable, but think of the enormous advantage for future occupants of a base on the moon or Mars, they could obtain fuel for their ships simply by going to the bathroom.
