Q&A Would it be possible with current rocketry to go from Earth to Mercury and then come back?

Leaving aside the matter of how well would humans fare on the surface of Mercury (we only have to factor in the weight of their life support: air, water, food and spacesuits), and assuming material...

Q&A Is it necessary for spaceships to include reverse thrusters for deceleration in space?

Set in the not so distant future, space travel becomes commonplace but is limited within the heliosphere. I'm thinking since it is fuel efficient and more economical to use gravity assist to slow d...

Q&A Good explanation for why aliens can't build nuclear engines?

"Aliens used uranium and plutonium to generate energy for thousands of years. However, by the time they got into space exploration, they've used up every last bit of it. That's why they'll have to ...

Q&A Will we need to replace conventional rockets to send manned missions further into space?

Currently, chemical rockets have taken men to Earth orbit and the moon by combusting rocket fuel to generate thrust. Even if we develop more efficient rocket fuels and can create significantly la...

Q&A 'Nuke the sky' to make a rocket launch a tiny bit easier

My aliens want to build the heaviest chemical rocket possible: They never were much into space travel, since their planets' gravity is about 1.5 of ours. They made lots of bad experiences fighting ...

Q&A Would lower gravity lead to earlier spaceflight?

This is in regards to the Tyranny of Rocket Fuel. Summed up: Heavier ships need more fuel which makes them heavier, etc. You end up with diminishing returns. This is compounded by higher gravity - ...
