Discussion Overview

The discussion revolves around the definition and scope of space physics, exploring its relationship with related fields such as astrophysics, atmospheric science, and plasma physics. Participants share their experiences and perspectives on what constitutes space physics and its significance.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants suggest that space physics is synonymous with astrophysics, while others differentiate between the two fields.
  • One participant notes that space physics often involves atmospheric science, indicating a broader scope than just astrophysics.
  • A participant shares their experience that space physics is typically associated with space plasma physics, focusing on the study of the Earth and solar system, including magnetospheres and solar phenomena.
  • Another viewpoint proposes that space physics can refer to conducting physics experiments in the absence of gravity, highlighting its implications for fluid dynamics and biology.
  • Some participants mention that certain academic departments may use the term "space physics" interchangeably with astrophysics, leading to potential confusion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definition of space physics, with multiple competing views presented regarding its scope and relationship to other fields.

Contextual Notes

There are unresolved definitions and assumptions regarding the terms used, as well as the specific areas of study encompassed by space physics.

What is space physics? Can you tell me?
 
Physics news on Phys.org
Stuff related with astronomy,astrophysics,etc. There are many subjects related to space and physics..
 
I've seen Space Physics used synonymously to mean Astrophysics. In my earliest years of university, I was majoring in Physics with options in Space Physics (Astrophysics) and Nuclear Physics. My baccalaureate (BS) would have been in physics had I not changed to Nuclear Engineering.
 
Many times when I've seen Space Physics listed as a research area it would involve a lot of atmospheric science.
 
Interesting question. Actually I wanted to go into space physics, but got into a school where they do astrophysics, so I ended up doing the latter. In my experience, space physics is usually short for space plasma physics. It's basically the study of the Earth and solar system, including magnetospheres, stellar wind, the physics of the sun, magnetohydrodynamics, etc. Space physics differs from astrophysics in that in astro, we can't actually go to the sites that we're observing and take in situ data. Space physicists, on the other hand, can send up probes and take all kinds of measurements about the solar system.

Of course, based on what Astronuc said, it seems that some departments or labs use the term "space physics" to refer to what is really astrophysics.

It can simply mean doing physics without gravity present. This is more interesting than it may appear- fluids behave very differently, for example. Biology is affected also.
 
Some physics relating to space is less astro- in nature. Planetary science, plasma physics, atmospheric science...
