NASA's Mars Helicopter Completes Flight Tests, Ready to Fly to Red Planet
The Mars Helicopter will launch as a technology demonstrator with the Mars 2020 rover on a United Launch Alliance Atlas V rocket in July 2020 from the Space Launch Complex 41 at the Cape Canaveral Air Force Station, Florida.
It is expected to reach Mars in February 2021.
Weighing in at no more than 1.8 kilogram, the helicopter contains more than 1,500 individual pieces of carbon fibre, flight-grade aluminium, silicon, copper, foil and foam.
The helicopter is a technology demonstration project currently going through the rigorous verification process certifying it for Mars, which has much thinner atmosphere than Earth's. The planet also drops to icy temperatures that can destroy sensitive electronics.
To ensure that the helicopter copes with those conditions, NASA has created a Martian atmosphere here on Earth -- a 7.62 metre wide vacuum chamber in JPL's Space Simulator, in which carbon dioxide, the chief ingredient of Mars' atmosphere, has been injected.
I wanted to provide a detailed post on this but I’ve not had the opportunity to do so. I also forgot about this post until I saw it recently so I had to follow up as promised.
Bypassing all the previous posts I'll reply to this as a standalone question not taking the context of this thread into account. The first quote below is the last question you put forward and the second quote is probably what led to your question so I'll address this.
Are you saying that there are some things in which it is not important to be an expert to hold a particular view?
so I don't know if this is an opinion that is echoed by the mainstream of experts in the field or if it is a minority opinion.
Expert opinion is not only important but the Qur'aan also advises to take matters to experts if the answer is not found directly in Qur'aan and Sunnah.
The problem with your question however, is the fact that being an expert is not a prerequisite of holding a view. The information and evidence that led to the view is what requires an expert.
So yes, being an expert makes the statement stronger where trust and reputation will help you make a decision but in no way is it required to hold a particular view.
Majority view also does not make something sound. Every new discovery is a minority opinion until it becomes mainstream so by definition being a minority opinion does not make it weak or unreliable.
At the same time, being mainstream does not make a belief sound. One example would be that scientists and all kinds of experts still, till today, believe that a human only uses 10% of his brain. This is still found in school textbooks and library books in the science section. But fMRI scans have revealed this isn't even close to reality. Now if a person who is not an "expert" found this out from an expert and states information based on this, would it become unreliable because the one who knows this is not a brain surgeon?
So yes, "it is not important to be an expert to hold a particular view" and to ask this specifically on anything that challenges your existing views would hinder learning. Always ask about the data, information, source, etc. and take it from there.
I do hope this helps and hopefully answers your question as well. If you prefer a reply more related to this thread and what the ongoing topic was including my post that triggered your questions in the first place then please let me know and we can start from there. No harm in clarifications if it's for better understandings. Jzk. Ws
Maulana Ali Mian nadvi RA has cautioned us while dealing with these type of subjects;
An attempted translation from urdu.
Exaggeration hurts us. Words like "west is nothing", "there is nothing to benefit from the west, it must be rejected outright". Remember when people realise that these discoveries and its benefits are true, then they shall mock us and reject us.
So dawah volunteers must be trained to accept reality and be moderate. While rejecting the western culture, we reject even their knowledge, we claim that there is nothing to benefit from their knowledge etc. We must say, "western knowledge must be respected and we must benefited from it as they are a necessity. But this knowledge is not enough to guide humanity to correct their behavior of humans and make them god fearing".
Jazakallah. What you said makes perfect sense, but for me this opens up a door to knowledge, and I am frightened of the consequences that knowledge will have for me. I am a muqallid in the truest sense, and I don't have the capability of sifting through varied expert opinions.
I have always been wary of conspiracy theories, but it seems I may now have to reconsider some of these theories and actually give weight to some of them. This is frightening.
This cannot be undone and I am sure it will be greatly appreciated.
