Some of NASA’s plans for space exploration
In late January, NASA announced that it had partnered with another US agency to build nuclear thermal rocket engines (核热火箭引擎).
With the current technology, a trip to Mars will take about seven months – the journey is about 480 million kilometers, according to NASA.
“Reducing transit time (航程时间) is a key component for human missions to Mars, as longer trips require more supplies and more robust (稳健的) systems,” NASA said in a press release.
…released on Jan 10 also revealed some exciting plans. As the agency’s lunar operations proceed, scientists wish to build an oxygen pipeline at the moon’s South Pole.
The agency also aims to explore other places in the solar system.
