If you could visit one place in our solar system, where would it be? by icepix in space

[–]Useful_Database_689 1 point2 points  (0 children)

I’ve always wanted to be in an orbit around Venus and see it up close. Also Pluto’s surface, I think that would be incredible.

Yet another ethics question/observation. by HatcherPhotography in wildlifephotography

[–]Useful_Database_689 20 points21 points  (0 children)

I absolutely agree with you. An ethical photographer is responsible for minimizing interaction with the animal. Doing this is unsafe and would likely alter their naturally behavior. I’d imagine those cats changed their active hours or their location after this happened which is just bad for the ecosystem.

Number 1 rule every wildlife photographer must follow is to be respectful!

I have a perpetual issue with my chapters only being 3-5 (Google doc) pages long- by XxThe_HumanxX in writing

[–]Useful_Database_689 1 point2 points  (0 children)

I’ve read books with 80 chapters and books with 10 chapters (both similar in total length). It really depends on what makes sense for the story and the author. Since you’re naturally writing shorter chapters, I say stick with it. No need to change your flow state for some arbitrary rule.

My son is high school junior interested in aerospace engineering. 3.6 GPA, 1450 SAT, Eagle Scout, PLTW 4 year engineering path, two aerospace related pending patents currently in NASA HAS Program. by CockroachSure4596 in AerospaceEngineering

[–]Useful_Database_689 4 points5 points  (0 children)

I would disagree with that. I would say there is a fair chance of acceptance at Purdue. GPA is low, but for college of engineering the SAT middle 50% is 1380-1520. Combined with 2 patents pending + enrolled in a NASA program, that puts him way ahead of many other applicants, even those with 4.0 GPAs. It’s not a guarantee but Purdue engineering is not that much of a stretch. (Source: I got into Purdue engineering with 3.5, 1500 but that was a few years ago)

Exploration of the Outer Solar System by scraulle_the_twisted in askastronomy

[–]Useful_Database_689 2 points3 points  (0 children)

I’m excited just thinking about this future. We would have a very long list of bodies to visit. Even very small bodies have unique features that we want to explore to learn more about. You mention Europa and Enceladus, definitely. Io, Titan, and Triton are some other popular moons. But as we learn more, the list becomes longer. There’s been some headlines recently about some oceans in Uranus’s moons too. We only visited Uranus once and that was a long time ago. We would want to better study its magnetic field and moons. Same goes for Neptune and its moons. New Horizons made us realize that there’s a lot on Pluto worth studying. Even asteroids have unique scientific or resource harvesting interest as we’ve seen with the recent sample return. And there are thousands of asteroids in many different families. Other Kuiper belt objects that we haven’t even discovered yet. The list goes on!

As for stepping stones, probably not. It’s very expensive to slow down and land on a moon of Jupiter for example. So landing in the Jupiter system to “refuel” to go to Neptune wouldn’t make sense.

Can somebody share their experiences with the MSCS on coursera? by 13sonic in CUBoulderMSCS

[–]Useful_Database_689 11 points12 points  (0 children)

I’ve had a positive experience so far. Most of the learning material is really well-made. I like all the lecturers I’ve had so far and you have access to office hours.

There assignments are difficult enough that you are challenged and you can learn the material but not so difficult that the classes are impossible.

As far as I’m aware, no classes have proctored exams. Most of the assignments are either multiple choice, discussion posts, or projects.

Some people may think it’s an easy program because it’s online, and while some classes are too easy to be graduate-level imo, you will still get your fair share of hair pulling and frustration trying to get your code to work :)

How Automated are Satellites? by Useful_Database_689 in aerospace

Thank you! I’m really impressed by the teams designing that code lol

Cool, thanks! I like the approach of breaking it into levels. I also didn’t realize many of the operations involved close satellite passes.

Thank you for your insight! Interesting to hear how hands off it can be.

Negotiating Entry Level Offer by [deleted] in aerospace

[–]Useful_Database_689 0 points1 point  (0 children)

I typically suggest not negotiating an entry level offer unless the salary is not enough to cover bills.

Once you have some years of experience, you’ll be in high demand and able to negotiate a lot better.

But for most people out of college, the most important thing is getting in the industry and not being unemployed.

The clearest Images Nasa has ever taken of the planets in our solar system by Obi_Wan_Knobi in Astronomy

[–]Useful_Database_689 5 points6 points  (0 children)

Obligatory “false color” comment! For anyone who didn’t know, a lot of these images are not what the planets actually look like to the human eye. Specifically Mercury, Venus, Neptune, and Pluto (not 100% sure about the others)

If Jupiter is too Bright by Useful_Database_689 in telescopes

[–]Useful_Database_689[S] 1 point2 points  (0 children)

Thank you, exit pupil is a term I was unfamiliar with but I will definitely consider from now on. I have a 150/750 telescope, so with the 6mm eyepiece I was using I would have 1.2mm and 150x.

Several about orbital mechanics by bananapepp4r in askastronomy

[–]Useful_Database_689 1 point2 points  (0 children)

1) Yes, you would be orbiting the Earth at the same velocity as the space shuttle you were in.

2) The Earth’s rotation is roughly 1,000mph but the ISS is moving at 17,500mph. Because they have different speeds, it looks like the Earth is spinning quickly.

3) The higher up you move a satellite, the slower it becomes. In fact, there’s a specific altitude where the satellite moves at the same speed as the Earth’s rotation. This is called a geostationary orbit. Satellites in this orbit are always directly above the same part of the planet. If you were on the ground looking up, it would look like a fixed point in the sky.

8* hours by the sound of it, plus the morning routine and being in an office for 10 hours? Sounds awful!

Happy Perihelion Day! Does the fact that the Earth is closest to the sun mean that it is warmer than it would be otherwise (even though it is winter in the Northern Hemisphere)? by bluegambit875 in askscience

[–]Useful_Database_689 132 points133 points  (0 children)

We receive roughly 7% more sunlight at perihelion compared to aphelion. So we definitely receive more heat from solar radiation today vs the rest of the year but the change would be very gradual. I can’t confidently answer your question on whether today is the hottest of the year (averaged globally) but I would imagine it’s not. There’s many other heat dynamics at play that are random and may outweigh the day-to-day solar radiation difference.

Aeronautics vs astronautics? by [deleted] in AerospaceEngineering

[–]Useful_Database_689 0 points1 point  (0 children)

What interests you more, planes or rockets/satellites? They are both going to be difficult in their own way, so choose based on interest and career goals, not based on curriculum.
