After years of waiting, the journey to the universe of Richard Branson on the Virgin Galactic ship this month should have been considered a reverent victory.0: 00/3: 03 namthay in it, this journey Attract significant criticism of its carbon emissions. With the fact that Jeff Bezos launches Blue Origin missiles on July 20 and SPACEX of Elon Musk planning for a mission of all people in September, The universe tourism industry is still seen that they are facing hitting questions about environmental impacts. "Carbon dioxide emissions are completely negligible compared to other human activities or even Chi is compared to commercial aviation, "NASA Gavin Schmidt's climate adviser told AFP. However, some scientists worried about long-term harmful possibilities when this industry is ready for steps Large development, especially in the moment the impact on the atmosphere in the rooftop is still unwind yet
. Virgin Galactic, suffered Many criticisms in CNN and Forbes newsletters, as well as on social media, because bringing billionaires Jeff Bezos - his founder on the universe on a trip lasting a few minutes on a train Pillars running with fossil raw materials, creating carbon emissions are equivalent to business class tickets from London to New York. "We have taken steps to balance carbon emissions from test flights of I am considering opportunities to balance carbon emissions for future customers' flights, and reduce carbon emissions in the supply chain, "Virgin Galactic galactic spoke to AFP. Flying across the Atlantics carrying hundreds of people, Virgin's flight only includes 6 passengers while emissions at 4
5 tons / person, according to an analysis published by French Astronomical Physics Roland Lehoucq and colleagues in The Conversation magazine. That number is nearly equivalent to driving a regular car around the Earth.SpaceShiptwo of Virgin Galactic uses a synthetic rubber to fuel and burn it in nitrogen oxide, a strong greenhouse gas. Fuel Pump Black Carbon on the upper floor, 30 - 50 km from the ground is 30 - 50 km. These particles can cause many effects, from sunlight reflexes and cause nuclear winter effects to speeding up Chemical reactions degrade the ozone layer. Virgin Galactic said they want to make 400 flights every year.So with spaceshiptwo space aircraft of Virgin Galactic, Blue Origin is much cleaner, according to a recent article of Martin Ross scientists from Aerospace, company Bezos posted on Twitter. That's because it burns liquid hydrogen and liquid oxygen as fuel and excreted steam. The reusable vertical release of Blue Origin caused ozone losses less than hundreds of times and pressure on climate less than 750 times compared to Virgin, according to the calculation of the space company. That doesn't mean it's completely clean
Ross told AFP: "need electricity to create liquid oxygen and liquid hydrogen. From there you can turn back and calculate the amount of electricity used to create push substances. It depends on how far you look at the supply chain ". When SPACEX offers 4 rich passengers on the space in September, they will use Falcon 9 missiles, according to the calculation showing equivalent carbon emissions. 395 Trans-Atlantic flights. .
