How many coins will be sold during the ICO?
Hopefully 3.000.000 SPM * Crossing fingers *
Is your service already offered by a centralized entity? If so, why does decentralizing it make it better?

Not really in that big that we will offer it from. I'd recommend reading the whitepaper to fully understand how it all will work out.
What are the biggest challenges you expect to face and how do you plan to overcome these challenges?
I think the biggest challenges that we will face is to be widely accepted for the people just like any other else crypto coin when they are released. Where not here to beat Bitcoin, Ethereum or whatever crypto you know of. We are here to solve and provide solutions that are better, faster and more reliable than traditional systems that are used today.
Are you taking an precautionary measures to ensure scammers will not be able to mislead investors into sending funds to the wrong address?

I think the best thing here is for people to use common sense and understand that if somebody reach out to you they're fake.
Are you offering a guaranteed rate of return to investors? (RED FLAG)
No. That would be unethica and that's not the spirit of Spaceium.
Who is on the team, what are their backgrounds & credentials, and do they have any public track records??
You can check the whitepaper. Page 28.

We have a premine of 4.000.000 SPM and the coins that Spaceium have will be used on developing the project further and further each year. I think you should read the whitepaper to fully understand the financial structure that we've built.
