What is the biggest obstacle to space travel currently?

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.

How close are we to traveling in space?

It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph.

Should NASA focus more on commercial space exploration?

Advocates of space commercialization believe private firms such as SpaceX and Orbital Sciences, both of which won contracts to ferry ISS cargo, can provide routine LEO access at a lower cost. They say NASA could then focus more on missions that push scientific and exploration frontiers.

Which country has sent the most people into space?

Only the United States has sent people beyond low Earth orbit, but experts say U.S. preeminence in space could be challenged. China became the third nation to independently launch a human into orbit in 2003 and its capabilities have since grown.

Why is NASA spending waning in the United States?

Consecutive U.S. administrations invested in education and scientific research to meet the Soviet challenge. These investments propelled the United States to victory in the so-called space race and planted the seeds for future innovation and economic competitiveness, experts say. Yet, since the 1990s, NASA’s share of federal spending has waned.

What is empty space?

Space isn’t truly empty like it appears – it’s actually full of energy and different parts of the Universe have denser pockets than others. To understand this, we have to go all the way back to the Big Bang, which inflated the Universe from the size of a marble to an unimaginable size.
