The crew found it to be better than that of Apollo but still unsatisfying, partially due to food tasting different in space than on Earth. [37]: 292–293, 308 The frozen foods were the most popular, and they enjoyed spicy foods [38]: 130 due to sinus congestion from weightlessness dulling their senses of taste and smell.
On Wednesday, Aug. 7, the agency held a news conference giving an update on the two astronauts who have been in outer space for 63 days — approximately seven weeks longer than expected ...
However, plants experience normal growth given that directional light is provided. [10] Normal growth is classified as opposite root and shoot growth direction. This being said, many plants grown in a space flight environment have been significantly smaller than those grown on Earth's surface and grew at a slower rate. [10]
Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies.It contains ultra-low levels of particle densities, constituting a near-perfect vacuum of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust.

Amino acids whose chirality is opposite to the norm are found on Earth, and these substances are generally thought to result from decay of organisms of normal chirality. However, physicist Paul Davies speculates that some of them might be products of "anti-chiral" life. [13] It is questionable, however, whether such a biochemistry would be ...
The Moon's density is substantially less than that of Earth, due to its lack of a large iron core. [3] On Earth , physical and chemical differentiation processes led to a crustal density of approximately 2700 kg/m 3 compared to the 3400 kg/m 3 density of the compositionally different mantle just below, and the average density of the planet as a ...
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
