This article is a list of notable unsolved problems in astronomy. Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed theory.
One beer company sponsored a graduate student's research into brewing beer in space, [2] and in 2017 another planned to sponsor research on the ISS with the aim of serving beer on Mars. [13] Making alcohol in space would be difficult; for example, conventional distillation would be impossible in zero gravity and the volumes of liquid required ...
Energy drinks vary wildly, but often fall within the range of 70 to 200 mg per serving. The source of the caffeine itself also depends on the brand, and it can ultimately impact the nutritional ...
Another problem related to long-term missions has been the design of medical care systems within space craft due to the limited amount of available space. Medical care systems for spaceships must include the technology necessary to heal exposure to toxic chemicals and gases, and chemical and electrical burns.
Material shielding can be effective against galactic cosmic rays, but thin shielding may actually make the problem worse for some of the higher energy rays, because of the increased amount of secondary radiation. [34] The aluminium walls of the ISS, for example, are believed to produce a net reduction in radiation exposure.
A record stay in earth’s orbit and a fine to Dish Network might have space debris in common. Space junk is causing problems — and experts think it’s just the start. Why it matters
In recent years, there has been an increase in research on the issue of how humans can survive and work in space for extended and possibly indefinite periods of time. This question requires input from the physical and biological sciences and has now become the greatest challenge (other than funding) facing human space exploration. A fundamental ...
For example, the crew members will be relatively autonomous from terrestrial mission control and will need to plan their work and deal with problems on their own. They are expected to experience significant isolation as the Earth becomes an insignificant bluish-green dot in the heavens, the so-called Earth-out-of-view phenomenon. [ 1 ]
