Testify

I just read from the news that Spacex successfully recollected their rocket after a launch which sent 8 satellites into orbit.
After a launch which sent 8 satellites into orbit was recollected by spacex according to the news I just read.

This is historical since it was never done before  by any other companies, or countries, to be exact, and the reason for doing this is that it saves a lot of money by taking advantage of reusable rockets.

Nobody else, be it countries or companies, have ever done this before, so it’s quite a milestone for them to save tons of money with reusable rockets

Never before has such an achievement been done, the innovation of using recyclable rockets has progressed this feild greatly.
90 percent of the cost of rocket launches comes from the first stage of the rocket, and we used to throw them away after every launch.

The first stages of rockets used to be thrown away after being launched, and the cost of those actually accounts for 90 percent of the total

After every launch the first stages of rockets used to be thrown away and they account for 90 percent of the total cost

By throwing away the first stages of rockets, which is a common practice before, we actually flush 90% of our cost down to the drain

The largest expense of shooting vehicles into space often happens when the first stages of the objects are not recycled and are instead thrown away.
Well technically it’s more like we have to because there was no way to recollect them precisely back to certain areas, therefore they had to spend a lot of money launching a rocket.

We had to throw first stages away before, simply because we don’t have the technology for recollecting them, therefore wasting money building new ones every time is a must

But from now on, thanks to Spacex, we do have a better, money-saving choice

Spacex gives us a new choice of launching rockets, which is obviously better and of course, money saving. Hats off to them

Nowadays we have a better money saving choice thanks to spacex.
