SpaceX had succeeded in winning much of NASA’s business, but in order to be awarded a military launch contract, a company needs special certification, and curiously, SpaceX had a very hard time becoming certified. Calling bullshit on the process, and knowing that the law requires there to ...
根据“We are looking at Mars situations. Simulations(模拟) on Earth will help us understand and know the challenges astronauts will face before they go.”可知,因为会了解在宇航员去火星之前所面临的挑战,故选D。 (2)题详解: 推理判断题。根据“NASA opened applications on August 6 and has strict...
"In order to land on the moon, in order to land on Mars, we're going to come down pretty much vertically," he explained. "Whether it'sSpaceX Option A, building their human lander for the Moon that we will fly, or other contractors that are coming online to take subsequent missions,...
Previous missions to Mars, like the Mars Odyssey spacecraft, have found radiation levels 2.5 times higher than those on the ISS. And there were times whenradiation spiked(likely related to solar activity) to much higher levels that. So how do you protect astronauts from this invisible threat?
Yeah, Mars is pretty great… if you’re not made of meat and don’t need to breathe oxygen. Otherwise, it’s incredibly hostile. It’s not much more habitable than the cold vacuum of space. First, there’s no air on Mars. So if you were dropped on the surface, the view would be...

Here's how to watch NASA's OSIRIS-REx mission attempt a daring mission: collect a sample from an asteroid 200 million miles away and return it to Earth.
Seismometers are a fairly basic piece of equipment, and given how much experience we have using them on Earth, adjusting them for Mars is conceptually simple. The designers needed to adjust for the different level of gravity, and the instrument needed to be extremely sensitive to pick up small...
The astronauts can also spend time with the plants in between the times when they were performing operations like harvesting. “They were able to take the cover off and look through the window on their off time,” Spencer said. And that turned out to be useful for the experiment as well,...
