Decompression.
propably the head gasket is gone, engine is lossing presure (loss of power) and smoke is coused by coolant or oil going into the cylinders
As I am a Indian and very keen follower of N.A.S.A and saddened at the loss of those lives lost in that spacecraft .
The loss of a species is called extinction.
The spacecraft used in Apollo 1 was called Command Module Block I, designated CM-012. It was intended to be the first crewed mission of the Apollo program, but tragically ended in a fire during a pre-launch test on January 27, 1967, resulting in the loss of the entire crew.
Astronauts conduct experiments, maintain the spacecraft, exercise regularly to combat muscle loss, perform spacewalks to repair and upgrade equipment outside the spacecraft, communicate with mission control, and take part in educational outreach activities.
It is called loss of fur or fur loss
the loss after depreciation incurred during the year is called as cash loss
So-called "loss of control" is actually a myth.
The addition of thermal energy is called heating, while the loss of thermal energy is called cooling.
Loss of infrared energy from the body is called thermal radiation.
The exterior of a spacecraft experiences very high temperatures upon reentry due to the intense friction and compression of air as it rapidly descends through the atmosphere at high speeds. This can reach temperatures exceeding 1,500 degrees Celsius (2,732 degrees Fahrenheit), which poses a significant risk of damaging the spacecraft's structure and systems. Effective thermal protection systems are crucial to shield the spacecraft and ensure the safety of its occupants and equipment during this critical phase of the mission. Failure to manage these temperatures can lead to catastrophic failure and loss of the spacecraft.
