For propelling a rocket, researchers set all the parameters of spacecraft based on the rocket equation. However, for developing a space-transportation system that can connect two different solar systems, the speed and size parameters adjustments of the spacecraft based on the rocket equation are the major hurdles. Even with most recent technological advancements and powerful rockets, researchers think that it would take nearly 50,000 Years to reach the neighboring Solar system, Alpha Centauri that is 4.37 Light Years from the Sun.
Researchers have been trying to generate advanced propulsion concepts in space in order to slash the transit time extensively. Few researchers have put forward a propulsion concept theoretically, which can generate an extensive thrust in “zero-gravity” conditions. The researchers have been calling this hypothetical propellant-free thruster, EmDrive. The concept came into discussions around the year 2000. The thruster works by generating electromagnetic radiations, particularly microwaves, from electricity and forcefully directing the radiations through a conical chamber. Theoretically, the microwaves release by exerting pressure against the chamber walls generating enough thrust to propel a spacecraft in cosmos.
According to the lab-generated prototype of EmDrive, it’s still uncertain whether it can generate thrust that would be enough to propel the spacecraft.
On a similar subject, NASA is looking to explore its neighbor planet, Mars. For this long-awaited exploration tour, the agency has been arranging several necessities for the astronauts. Cosmonauts would require the bulk of food for the 2.5-year Mars exploration mission. Carrying prepackaged freeze-dried food in the spacecraft will consume lots of space and fuel for transportation.
NASA scientists have been looking for some effective ways to grow vegetation in space. This would not only solve the excess weight and space consumption problem but also offers fresh diet to the astronauts associated with the mission. NASA’s Kennedy Space Center researchers have been conducting several experiments through which plants and vegetables can be cultivated in low-gravity environments.
The infinite Universe and space bodies have been interesting for Deneen since childhood. Deneen, thus, chose writing as a career with the hopes of obtaining an endless amount of information. Her love for reading books such as Cosmos, Death by Black Hole, A Brief History of Time, and more has helped brush up her skills and provide factual Universe or planetary data. She is an expert writer and consultant and has delivered multiple publications in last some years.
