How were the gravity scenes filmed in the movie “Deep Impact”?
In the film Deep Impact the scenes where all the astronauts are inside the messiah spaceship seemed fairly realistic with gravity e.g. they moved slowly and floating etc.
How did they film the scenes within the spacecraft cabin?

I don't know how good their source is, but the website VFXHQ says the effect was done by hanging people and objects from wires and then removing the wires in post-production.
Zero gravity in the Messiah was accomplished by hanging the actors and props on wires, wires which then need to be painstakingly removed. Amidst all the great 2D work, one wire removal apparently went awry--look carefully as a Messiah crewmember tows a piece of equipment across the ship.

That article doesn't explain how wires are removed from the final images, but there are various techniques which involve in some way "painting over" the wires. This article describes various techniques:

How did they do the gravity scenes?
For the space scenes, they attached each actor to multiple wires to simulate the zero gravity movement. Of course, while the movement might look zero gravity, operating on the wires didn't feel like zero gravity, meaning no amount of zero gravity training could help the actors simulate the real thing.How did they film the weightless scenes in the movie gravity?
Early on, the filmmakers decided to map out the entire movie with computer-generated imagery in a process they called previsualization, or "previs." Animators adhered to the rules of objects in weightlessness as they previsualized the film, shot by shot, using highly detailed computer graphics.How did they film the zero gravity scenes in the Martian?
We never did the sort of things that they did on Apollo 13, when they took them up in what they call the 'Vomit Comet', which gives the weightlessness. You get 40 seconds of weightlessness to perform a scene, and then go back up again and do it again.How do they simulate gravity in movies?
To simulate weightlessness, a 30-ton rotating ferris wheel-type set was built for actors to stand at the bottom of and walk or run in place while the set rotated in sync with the actors' speed to keep them at the bottom of the wheel as the set turned.GRAVITY \
