When building a spacecraft what are the 3 things NASA is most concerned about?

If the ship is strong enough to support the launch. If the ship can withstand high pressure and temperature rates. If the material is resistant and light at the same time.

Explanation:

When a spacecraft is built, many tests must be carried out over the years to prove that the spacecraft has the ability to launch into space and fulfill its mission efficiently. In addition to supporting the launch, these ships need to be built in a way that will withstand space conditions that are very different from terrestrial conditions.

For this reason, there is a concern if the ship can withstand extreme situations of temperature, pressure, gravity, weight, among others. In summary, we can say that three of the biggest concerns that NASA has in building spaceships are:

If the ship is strong enough to support the launch. If the ship can withstand high pressure and temperature rates. If the material is resistant and light at the same time.

Codominance is when alleles have the same amount of dominance and both are expressed in a heterozygous individual(ab blood type, roan cow). in a heterozygote with incomplete dominance, the phenotype seen is an intermediate of the dominant and recessive phenotype.(pink flowers when the dominant form is red snd recessive form is white)
