Will space travel ever be commercial?
Currently, Blue Origin has a Federal Aviation Administration license for human space travel through August 2021. If the first crewed flights are successful, the public can potentially start space tourism flights in early 2022.
What are some of the major challenges facing space travel today?
Problem: Space travel can present extreme environments that affect machine operations and survival. Like humans, machines are impacted by gravity, propulsive forces, radiation, gases, toxins, chemically caustic environments, static discharge, dust, extreme temperatures, frequent temperature variations and more.
Has any astronaut died in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
Will we ever be able to go to interstellar space?
There’s no law of physics that outright forbids it. But that doesn’t necessarily make it easy, and it certainly doesn’t mean we’ll achieve it in our lifetimes, let alone this century. Interstellar space travel is a real pain in the neck. If you’re sufficiently patient, then we’ve already achieved interstellar exploration status.
What are the alternatives to manned interstellar travel?
Either way you look at it, there’s a serious chance that manned interstellar travel would require multiple generations of humans to live on board (which leads to the space and fuel problems in the previous section). The leading alternative in science fiction is some form of stasis, or prolonged unconsciousness.
Is interstellar travel just a Hollywood fantasy?
It’s for these reasons that interstellar projects are often resigned to the realms of science fiction. In a recent New York Times op-ed, Adam Frank, professor of physics and astronomy at the University of Rochester, went on the offensive, saying that interstellar travel is nothing more than Hollywood fantasy.
Why didn’t humanity ever succeed at intercontinental travel?
But in the case of intercontinental travel, mankind did succeed, driven by a basic need to explore. But for mankind to become interstellar, the motivations are a lot less clear and the technologies needed are less certain. It’s for these reasons that interstellar projects are often resigned to the realms of science fiction.
