NASA aims to travel to the moon again—and beyond. Here’s a look at the 21st-century race to send humans into space.
NASA to outsource future of space flightSeth Borenstein
After his successful flight to space, Jeff Bezos pushed back on criticism that launching rockets was a vanity project for billionaires, saying that the future of the planet — and those who inhabit it — depends on what can be accomplished in space. ...

Design Analysis of the High-Speed Experimental Flight Test Vehicle HEXAFLY-International Achieving airbreathing hypersonic flight is an ongoing challenge with the potential to cut air travel time and provide cheaper access to space. Waverider designs are a potential candidate for achieving hypersonic cruis...
1从第一段最后一句话“Any flight to other solar systems is even more distant,but a huge advance in space technology could drive space exploration into realms currently explored only by science fiction.”可看出,技术上的突破才能使进入太阳系成为可能,B、C、D三项只是影响太空探索的未来的因素。故选A。
During the first years of flight, safety measures were introduced that are still in use today. In 1912, crowds in Chicago’s Grant Park watched Tiny Broadwick become the first woman to jump from an airplane. (The pilot was aviation pioneer Glenn Martin.) Tiny had gotten her start leaping ...
Space flight may be about to undergo a transformation far more radical than anything planned by national or international space agencies. In the next fifteen years or so, there could be a fleet of fifty space-planes carrying a million people into orbit about the Earth each year, at 10,000 ...
