    Set your clocks for 4:32 pm(eastern time)on May 27th, 2020. If everything goes as planned, a rocket will launch from Kennedy Space Center in Cape Canaveral, Florida.

1. So what’s the big deal? The big deal is collection of firsts set to blast off on the 27th of May. The first humans carried aboard a rocket developed by a private company. The first humans aboard a reusable rocket.

Ever since the opening days of the space age, NASA has designed, built, and flown its very own rockets, and capsules. 2. The privately-held company Space X will be providing the big rocket boost(加湿器)needed to get NASA’s astronauts to the space, aboard a Falcon 9 rocket topped with a Dragon crew capsule.

3. It is trying to make access to space cheaper, chiefly through the use of reusable rockets- once the payload is delivered into orbit, bring the rocket back down the Earth and polish it up for another ride.

In the meantime, NASA has spent the past decade in a highly bureaucratic version of hell. After the sad end of the space shuttle program in 2011, the American space agency was forced to rent seats on Russian made and Russian launched Soyuz rockets to get astronauts up to the International Space Station.

4. And now, if everything goes as planned on May 27th, we will make human access to space cheaper, more reliable, and absolutely easier. 5. Space tourism? Moon bases? I would say that the sky is limit, but the sky is just the start.

A.But this time, it’s different.

B.Rockets go off all the time from the Earth.

C.This made for great wounded national pride.

D.Most of the astronauts haven’t made it up into space.

E.Space X has spent the past decades working tirelessly.

F.NASA has been developing a new space launch system.

G.It’s impossible to say what kind of revolutions that might lead to.
