NASA is conducting tests on the new generation of vehicles that will transport astronauts to travel on the moon, in field tests in the Arizona deserts
NASA is conducting experiments with the new generation of vehicles that will transport astronauts on trips to the moon, in field tests in the Arizona deserts. Engineers, astronauts and geologists are driving all-terrain vehicles on similar contours on the surface of the moon to test whether their performance is indeed similar to that published by the developers when humans return to the moon, hopefully by 2020.
One configuration of the lunar rover allows crew members the freedom to get on and off whenever they want, but they must wear spacesuits at all times to protect them from the lunar environment. A second configuration allows adding to the vehicle a small pressurized module (SPR) on the chassis where the astronauts can sit inside in short sleeves while driving the vehicle, and don spacesuits when they want to leave. Other concepts that have been tried include robotic rovers and improved spacesuits. For the pressurized vehicle, the spacesuits will hang outside the spacecraft, but the astronauts will be able to enter the contents from inside the vehicle.
In the first week of testing, the vehicle went on a full-day drive to test the performance of each of the configurations. These were the longest trips that any of the typhus fathers had taken so far, but in the second week the group will conduct additional experiments, this time for three-day trips in the desert inside the vehicle in order to test its performance and whether it is comfortable enough for long trips.
Two teams including one astronaut and one geologist participate in the field experiments to test lunar rover concepts that will allow astronauts to explore the moon much more deeply than before. and build a base that will allow astronauts to be housed in space for the long term for the purpose of performing a variety of scientific experiments. During the first use of these vehicles on the Apollo missions, the astronauts made nearly twenty forays onto the lunar surface. With each successful mission, NASA improved the capacity of the vehicles and increased their number and the duration of the missions that the astronauts could perform on the surface of the moon.
The concept of the SPR (compressed module) can provide astronauts with a convenient form of transportation, and allow them flexibility in working within it without the limitations dictated by space suits. The flexibility is achieved thanks to the wheels that rotate on an axis and which make it possible to make a movement similar to a crab's walk to help maneuver the vehicles on difficult sites. The vehicle's cockpit does not obstruct the view of the surface ahead.
The mobile chassis in the uncompressed vehicle (UPR) where the astronauts in spacesuits drive a rotating turret can also be used in the compressed vehicle. The astronauts may ride in the turret even when the vehicle is in compressed mode, reducing the time needed to make changes to the suits. The modular design will also allow the connection of a variety of tools, many of which will be required for a specific task, such as cranes, cable wheels, cranes and more.

Really idiotic now that I think about it SILLY ME
queeny:
An engine that will pump a vacuum into it and force it down to float!
I must admit it is original!
WTF if it's also idiotic and senseless.

Thanks, corrected.
Some wording problems:
"The control cabin of the vehicle does not interfere with the view of the surface ahead."
"...the astronauts in spacesuits drive a spinning wheel..."
And more.
By the way, if it is possible to add a feature that sends commenters an email every time there is a new comment, it will help a lot to stimulate the discussions.
Usually when I respond, later I don't remember to check the article again to see if I was answered or new interesting comments were added.
Abby, I am also an avid reader of the site. I agree with response 8. Censorship is an anti-scientific approach, and should be avoided except perhaps in cases of profanity. Give commenters the freedom to steer the discussion in the comments as they see fit. And to all the enlightened commenters on the site - just don't relate to those who try to lower the level. In the end they will give up.
I suggest not to censor or comment. A method that over time lowers the air pressure under the bully's wings. (Of course I'm talking about the third law of thermodynamics and not the first)
You watch too many reality shows.
girl next door…
You are rude and vulgar. My father works for you? Do you pay for the website?
The person labors for 12 years on a website open to everyone... who are you anyway?, what is your contribution to the public?
The site only gets better and better with time, your knowledge of the connection between political affiliation and professional occupation is delusional and indicates exactly who you are.
There are those who are happy to see them come, they are happy to see you go.
Bye and no goodbye.
Rather, the series of troublesome and provincial articles on the McCain-Obama topic is a good example of the decline that has occurred on the site.
First, my ^#^ is interested in what McCain and the Bamba are doing on science issues.
This is supposed to be an Israeli site and not an American one - don't you have an iota of national pride, not to mention shame?
Second, any attempt to predict who will be better in any subject - is debatable and pathetic at best. Since when do elected officials uphold their platform?
I will admit that I read three sentences in each article and could not continue any longer due to boredom and curiosity.
The issue of the cynical use of Rabin's murder for the purposes of political incitement and witch-hunting is, in my opinion, a matter for first-rate scientific investigation and far from being a "conspiracy theory" as you say.
If you had listened to my advice and devoted a small part of the energy you devoted to the aforementioned series of unnecessary articles, to the professional preparation of an article on this topic, you would have bought your world, and you have nothing to fear, the vast majority of people in the country who are interested in science - belong to the right. The leftists are only concerned with journalism and grass science which do not require a particularly high psychometric score.
It's interesting what you say, so you probably don't understand what a level is. Every day there is news more interesting than the previous one, and show me another site that analyzed, for example, the opinions of the two candidates for the presidency of the United States on the really important issues - science and education.
If there are articles here about conspiracy theories - they are meant to be refuted, and even then only on scientific topics. On political issues, the science website is not the place to express yourself. There are enough other sites that would be happy to start arguments about these topics.
To my father
Unfortunately, in recent months I have noticed that there has been a drastic drop in the level of articles on the website. In my opinion, the new policy of unjustified censorship is only a symptom of the phenomenon.
The science website was originally intended to promote science and research. And where there is no freedom of thought and opinion - there is also no science and research, only ayatollahs.
As for the last censorship that was applied - I have the feeling that the reasoning you gave is just an excuse.
I hope you come to your senses soon before the site goes down for good.
to the neighbor Your comments that were deleted (not all of them, two were confirmed after checking) are not relevant to the topics of the articles and we have started to be careful about it.
As for your proposal for the article, the topic is not relevant to the science website, and we do not generally believe in any conspiracy theory.
After a week in the field with such a Zhalom, you pray that next time it will only be a child
