IN space an object can not undergo projectile motion so thats irrelevant siNce gravity doesn't act there also there is no datum like that on earth it is the surface that acts like a datum.



so the difference is :



in space weather you throw an object it always follows a staright path weather it is thrown from the datum(imaginary)for a angular projectile motion or at a distance from it for a horizontal projectile.

Maximum height from the surface is reached when s in the component of the velocity of projectile becomes 0 (zero)

Using the kinematic formula we get



v2u2=2gh



As the force of gravity is acts against the direction of vertical component of initial velocity so it is considered as  deceleration.

Substituting various values we get



02(usin)2=2(g)h

h=u2sin22g



Acceleration due to the gravity on the Earth is taken as g=9.81ms2 and acceleration due to gravity on the surface of the Moon is given as =1.625ms2



From the derived expression for maximum height we notice that for the same initial velocity and the same angle of projection we get



h1g



Thus the Maximum Height attained in space will be greater than on the surface
