What are the differences between the space vision of the two tech giants? Spacex ceo elon musk has a markedly different vision, fresh from launching the falcon heavy heavy lift orbital rocket on its first commercial flight. In april 2019, attention has now turned to a follow up rocket designed to transport humans to mars and beyond. The starship first unveiled under the name bfr in september 2017, is designed to replace all of spacexs existing rockets and its liquid oxygen and methane engine design mean humans can use it to return from mars and even explore further into space. Musk has declared his goal of erecting a city on mars by 2050, with propellant depots established to further reaches of space. He said in september 2018, as he was unveiling a trip around the moon for 2023, that there are so many things that make people sad or depressed about the future, but i think becoming a space faring civilization is one of those things that makes you excited about. The future spacex president gwen shotwell has even described these trips as one of multiple paths to survival bezos. On the other hand, while he supports the goal of space exploration, is very much a fan of keeping his mail directed to earth. He told space news that my friends who want to move to mars, i say: do me a favor and go live on the top of mount everest for a year first and see if you like it, because its a garden paradise compared to mars.

So we go to space to protect this planet. This is why the company is named blue origin, blue planet, its where were from, but we also dont want to face a civilization of stasis, and that is the real issue. If we just stay on this planet, he first unveiled new glenn in september 2016., the rocket marks a dramatic leap forward from new shepard, which is only capable of suborbital launches. New glenn will power heavy orbital launches, with a reusable booster to save on costs. Its part of bezoss plan to foster a new space economy with more than one million people living and working in space using earth as their home anchor. How different are these two rockets, these two rockets, the next stage and the two firms plans, show how these visions are panning out in new ways. Specifications new glenn is expected to measure around 22 feet wide and somewhere between 269 to 311 feet tall. The rocket can lift 13 metric tons to a geostationary transfer orbit and 45 metric tons to low earth orbit. Its 22 foot faring is a key selling point as the firm claims it offers double the usable volume of any current launch vehicle. That means bigger payloads going to space, which could make it more attractive to customers. Starship sn20 is a beast of a machine. The booster alone stands about 230 feet or about the same height as the statue of liberty. The entire stack will stand about 400 feet tall once the 150 foot tall top stage is mounted making it.

The largest rocket ever designed to go to space starship should be able to put 100 tons into low earth orbit and recover both the first and second stages. It is intended to refuel in orbit from a starship tanker, so it can carry 100 tons of payload to the surface of mars or the moon engines. New glen uses what blue origin refers to as the worlds most powerful liquid oxygen and liquefied natural gas engine. The be4, which provides 55 000 pounds of thrust it, uses seven of these to generate 3.85 million pounds of thrust for the first stage at sea level. A further two be3u engines on the upper stage will be powered by liquid dihydrogen and oxygen. The team finished the engine in march 2017 and tested it later that year, starship takes a different approach. The methane oxygen propellant raptor engines will be the main propulsion system for both stages of the starship system. Starship second stage will use three sea level, optimized raptor engines and three vacuum. Optimized raptor engines, the sea level engines are planned to be identical to the engines on the super. Heavy booster transport use in space is expected to use a vacuum. Optimized raptor engine variant to optimize specific impulse to approximately 8 300 miles per hour. Starship is being designed to use pressure, fed hot gas reaction control system thrusters using methoxy gas for attitude control, including the final pre landing pitch up maneuver of the second stage from belly flop to tail down and for stability during high wind landings up to 37 miles Per hour, material and construction, new glen is built with traditional, expensive milled aluminum alloy panels being a two stage: orbital launch vehicle with a reusable first stage and expendable second stage.

Both stages will use ortho grid, aluminum tanks with welded aluminum domes and common bulkheads and use etogenous. Pressurization starship has a stainless steel structure and tank construction. Its strength to mass ratio is better than the earlier spacex design. Alternative of carbon fiber composites across the anticipated temperature ranges from the low temperatures of cryogenic propellants to the high temperatures of atmospheric reentry. Some parts of the craft will be built with a stainless steel alloy that has undergone a type of cryogenic treatment, in which metals are cold, formed and work to produce. Cryo treated steel dramatically lighter and more wear resistant than traditional hot rolled steel, which rocket will go to mars. Spacex has been clear about its intention to use the starship to go to mars. The september 2017 plan covered an unmanned launch of two cargo bfrs in 2022, followed by two manned and two unmanned ships in 2024. Musk has subsequently suggested that these launches will come after the mission around the moon, scheduled for 2023. The company still maintains an ambitious timeline for getting to mars and starting a colony, its aiming for a city as early as 2050 dedicated to scientific research and understanding more about the red planet. The propellant depot could also enable explorers to move further into the galaxy blue origin is taking a different approach. Instead of focusing more on supporting people living and working in space, new armstrong, a future rocket that is expected to come after new glenn could support trips to the moon, mars and beyond.

However, bezos has been keen to underline his companys goal to support millions of people working and living in space instead of jumping to mars for survival reuse. New glenn is expected to have 25 reuses per rocket, but starship hit different. Hundreds of reuses starship is going to be absolutely unbeatable. The economies of scale with it being the first and only rocket to be mass produced in huge quantities on a production line and can be reused. Hundreds of times makes it undefeatable. Elon musk intends to build between one thousand and three thousand of them for his mars colony, plus a fleet of refueling tankers and super heavy boosters. If the sub orbital airline business takes off, there could easily be hundreds more required for that too. Launch price blue origin has invested 2.5 billion dollars to date. Musk has suggested that the spacex bfr will cost around 5 billion to develop, but the eventual ship costs less to create starship is projected to use 2 million. New glenn will have a hard time being the starship price, because the latter is leveraging the economies of scale of falcon 9. by the time that blue origin is flying, the new glen spacex will be getting starship orbital and the game will be over 100 tons to Orbit for just 2 million adam the ability for the spacex system to be refueled in orbit, allowing this high payload to be taken anywhere in the inner solar system and its hard to consider what could possibly be that which rocket wins your heart.
