To return second stages of its rockets, SpaceX can use huge balloons

When SpaceX just announced plans to return the first stage rocket Falcon 9, many experts doubted the adequacy of Elon musk. Now, however, SpaceX gets the first stage after all runs, and even the first flight of the heavy carrier rocket Falcon Heavy has completed a successful return of two of the three boosters.

In addition to the first stages of the SpaceX recently trying to return the fairing payload. These are “shields” covering the payload inside the second stage. Each worth $ 5 million (two of them), that is, their return and reuse can significantly reduce the cost of launch. By the way, it now stands at 62 million dollars.

In the photo above — the ship of Mr. Steven intended to capture the fairings. While he only once tried to catch these elements, but failed.

Yesterday Elon Musk tweets plans to return the second stages of their rockets. He did not describe the details, noting only that it can be done with giant balloons. Only you are likely a little wrong to imagine this picture.

Why the second stage it is impossible to return the same as the first? The problem is that the first discharged at a relatively low altitude when the rocket has not reached the maximum speed. The second is, in fact, reach orbit and very high speeds. So to start this subassembly to slow down. To use this fuel, probably not profitable, because the decrease of the maximum mass of the load.

The balloons, which said Musk in the first place is not needed for a gradual decrease in booster. They need to increase the resistance to motion of the rocket. More specifically, Elon claims that this decision will allow two orders of magnitude (about 100 times) to reduce the ballistic coefficient. If is easier, the lower the number, the more air resistance. Given that the second stage reaches a height where the air density is extremely low, in order to reduce its speed requires a really huge balloon.

Unfortunately, as I said, no details. How long SpaceX is working on this idea is unclear. Musk sometimes voiced some projects when they are almost ready to start. So, quite possibly, in the near future, we’ll see how SpaceX returns in General, all major parts of the Falcon 9 rocket.

  1. I’m not on board with this post Your reasonings are fautless, but nevertheless it’s not possible to depend upon whatever strangers may believe Please clarify some things, because I believe you’re an insightful writer and I would like to see more from you!

  2. Hey, how’s it going?

    I want to pass along some very important news that everyone needs to hear!

    In December of 2017, Donald Trump made history by recognizing Jerusalem as the captial of Israel Why is this big news? Because by this the Jewish people of Israel are now able to press forward in bringing about the Third Temple prophesied in the Bible

    The Jewish people deny Jesus as their Messiah and have stated that their Messiah has been identified and is waiting to be revealed They say this man will rule the world under a one world igion called spiritualism

    They even printed a coin to raise money for the Temple with Donald Trumps face on the front and with king Cyrus'(who built the second Temple) behind him On the back of the coin is an image of the third Temple

    The Bible says this false Messiah who seats himself in the Third Temple will be thee antichrist that will bring about the Great Tribulation, though the Jewish people believe he will bring about world peace It will be a false peace for a period of time You can watch interviews of Jewish Rabbi’s in Israel speaking of these things They have their plans set in place It is only years away!

    More importantly, the power that runs the world wants to put a RFID microchip in our body making us total slaves to them This chip matches perfectly with the Mark of the Beast in the Bible, more specifically Revelation 13:16-18:

    He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name

    Here is wisdom Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666

    Referring to the last days, this could only be speaking of a cashless society, which we have yet to see, but are heading towards Otherwise, we could still buy or sell without the mark amongst others if physical money was still currency RFID microchip implant technology will be the future of a one world cashless society containing digital currency It will be implanted in the right-hand or the forehead, and we cannot buy or sell without it! We must grow strong in Jesus AT ALL COSTS, DO NOT TAKE IT!

    Then a third angel followed them, saying with a loud voice, “If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name ” (Revelation 14:9-11)

    People have been saying the end is coming for many years, but we need two key things One, the Third Temple, and two, the technology for a cashless society to fulfill the prophecy of the Mark of the Beast
