The synonym for innovator and a NASA program for unmanned probes is Pioneer. Pioneer 10, launched in 1972. and Pioneer 11 launched in 1973. were the first probes that visited the outer planets and went beyond Pluto, Kuiper belt and into interstellar space. They both carry the gold-anodized aluminum plaque with naked human male and female and a map to Earth, designed by Carl Sagan, in case they are found by an extraterrestrial civilization outside the Solar system.

Explanation:
Taking into account the definition of calorimetry and sensible heat, the amount of energy required is 68.8 J.
<h3>Calorimetry</h3>
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
<h3>Sensible heat</h3>
Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
In this way, between heat and temperature there is a direct proportional relationship. The constant of proportionality depends on the substance that constitutes the body and its mass, and is the product of the specific heat by the mass of the body.
So, the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where:
- Q is the heat exchanged by a body of mass m.
- c is the specific heat substance.
- ΔT is the temperature variation.
<h3>Energy required in this case</h3>
In this case, you know:
- Q= ?
- c= 0.215

- m= 20 g
- ΔT= Tfinal - Tinitial= 88 C - 72 C= 16 C
Replacing in the definition of sensible heat:
Q = 0.215
× 20 g× 16 C
Solving:
<u><em>Q=68.8 J</em></u>
Finally, the amount of energy required is 68.8 J.
