The lecture explains that the privatized spaceflight industry will not benefit science and the public. This is against the passage, which claims that the privatized spaceflight industry will bring great benefits to both science and the public. The lecture shows the following three reasons.
First, private space travel will be extremely expensive. Space travel needs a complicated controlling system, which is very costly. Moreover, new design of spaceship will be tested and retested many times before they can be operated formally. These costs can make price of tickets for space travel to be too high. In addition, price of tickets are unlikely to fall fast. This directly questions the passage, which describes that private space travel will make spaceflight more cheaper.
Second, privatization of space travel will delay, even prevent the rate at which important scientific discoveries occur. The best engineers could be attracted by high salaries provided by private spaceflight companies. They might do commercial researches of little scientific value. This will suffer the serious scientific researches. This opposes the passage, which points out that privatization of space travel will accelerate the rate of scientific discoveries.
Third, taxpayers will pay the bills of space tourism. Space tourism needs not only spaceships, but also space stations, spaceships airports and so on. These costs will be paid by government. Also due to a huge amount of invest, private individuals or companies could not afford such a great sum of money. Government have to fund this undertaking. The bills will be paid by taxpayers. By contrast, the passage demonstrates that the financial burden on taxpayers will be eased significantly, disproving the lecture.
The lecture illustrates three reasons to counter the passage as follows: private space travel will be extremely expensive, and privatization of space travel will delay, even prevent the rate at which important scientific discoveries occur, and taxpayers will pay the bills of space tourism.

This directly questions the passage, which describes that private space travel will make spaceflight more cheaper.
Second, privatization of space travel will delay reduce, even prevent the rate at which important scientific discoveries occur, or stop such discoveries altogether (You can't just combine fragments from two sentences in the given material into one and assume it'll be correct.). The best engineers could be attracted by the high salaries provided by private spaceflight companies. They might do commercial researches of little scientific value. This will cause suffer the serious scientific researches to suffer (You cannot 'suffer' something or somebody. You can make somebody/something suffer.). This also opposes the passage, which points out that privatization of space travel will accelerate the rate of scientific discoveries.

(If your point is the lecture opposes the passage, keep it consistent. Do not change your point to 'the passage opposes the lecture'.)
