weight·less·ness

(wāt'les-nĕs),
The psychophysiologic effect of zero gravity, as experienced by someone falling freely in a vacuum (for example, astronauts in a stable orbit). A temporary state of simulated weightlessness can be achieved during powered flight within the earth's atmosphere by traversing an inverted parabolic curve where gravitational pull and centrifugal force cancel each other out.
Farlex Partner Medical Dictionary © Farlex 2012
A state in which there is no gravitational effect on a body or material
Physiologic effects Bone mineral loss, altered blood chemistries, weakened immune system, variable heart rate, arrhythmias, loss of skeletal and cardiac muscle mass and strength, increased urinary loss of nitrogen and phosphorus, motion sickness, and redistribution of fluids that are normally pooled in the lower torso and legs, resulting in a ‘fat face’

On Earth, Philae weighs 220 pounds (100 kg), but on Comet 67P it weighs less than a feather because of very low gravity! Scientists had equipped Philae with harpoons to anchor (attach) the probe to the comet's surface.
Without the probe being firmly tethered to the ground, drilling could destabilise it in the low gravity.
The challenges are many for the lander, from the small, uneven target to the comet's very low gravity. If the lander comes down too hard, that lack of pull could lead the probe to bounce, some scientists think.
