Question

name the visible layer of the sun.
give an estimate of its temperature

Answer 1

Answer:

NASA is performing a series of tests to evaluate how astronauts and ground crew involved in final preparations before Orion missions will quickly get out of the spacecraft if an emergency were to occur on the pad prior to launch. In the hours before astronauts launch to space in Orion from NASA’s modernized spaceport in Florida in on the agency’s Space Launch System rocket, they will cross the Crew Access Arm 300 feet above the ground and climb inside the crew module with the assistance of ground personnel trained to help them strap into their seats and take care of last-minute needs. The testing is helping engineers evaluate hardware designs and establish procedures that would be used to get astronauts and ground crew out of the capsule as quickly as possible. Flight and ground crew are required to get out of Orion within two minutes to protect for a variety of failure scenarios that do not require the launch abort system to be activated, such as crew incapacitation, fire or the presence of toxins in the cabin.

I Hope it will help!
