Wiens paints the portrait of one of the most exciting scientific stories of our time: the new era of robotic space exploration. Starting with NASA's introduction of the Discovery Program in 1992, scrappier, more nimble missions became the order of the day, as manned missions were confined to...
Most American space probe missions have been coordinated by the Jet Propulsion Laboratory, and European missions by the European Space Operations Centre, part of the European Space Agency (ESA). ESA has conducted relatively fewer space exploration missions in the past (one example is the Giotto mis...
If we ever want to send humans to Mars, we’ll need to find resources there which can help sustain a mission. One of the most essential resources for crewed missions is water, and now international space agencies want to find a way to locate it on the red planet. NASA has partnered wi...

Musk hopes the first Starship missions to Mars will launch in 2026. NASA is also working on their own rocket systems. The agency is developing a nuclear propulsion(核推进)system.What will humans do when they get to Mars?There are a lot of ambitions as to what we will do when we get ...
The natural resources are coveted because they could supply drinking water, air, and rocket fuel for future missions, ushering a new era in spaceflight. The success also means India has been one of countries who have landed a spacecraft on the moon. The victory comes four years after India...
[ 2024 原创] So far, humans have sent 28robotic missions to Mars. The Martian rovers and satellite observers have together showed the Red Planet's chemistry, topography(地形) , and some of its history. Thanks to these missions, we now know liquid water once flowed across the planet's surf...
10 to 20%, while a random mapping approach led to less than 10% gain in uncertainty reduction. In the future, their system could help to optimize the use of copters to enhance rover navigation during Mars exploration missions by considering the actions of the rover and copter in conjunction...
As previous Moon missions have only landed on the Earth-facing side, so the landing is seen as a major milestone (里程碑) on space exploration. A last crewed landing was Apollo 17 in 1972. 相关知识点: 试题来源: 解析 短文改错的答案请见解析 1. 本题主要考查副词。文章第一句,has landed...
Like its orbiting predecessors, the Chang'e 3 mission is planned as a precursor(先驱)to further robotic lunar exploration missions, including Chang'e 5, a sample return mission planned for 2017. Following these automated missions, a manned landing may be conducted around 2025. ...
