_why-do-bananas-turn-brown.webp "Ever wondered why bananas go from green to yellow to brown? Join us as we uncover the fascinating science behind the banana ripening process. This video dives deep into the role of ethylene gas in transforming bananas from unripe and green to sweet and yellow, and eventually to overripe and brown. Find out how you can control the ripening process and why bananas ripen faster when placed in a paper bag. Perfect for science enthusiasts, food lovers, and anyone curious about the natural world!")

_how-to-become-an-astronaut-with-nasa.webp "Astronaut Selection and Training-- Following the preliminary screening of applications, a week-long process of personal interviews, medical screening, and orientation are required for both civilian and military applicants under final consideration. Once final selections have been made, all applicants are notified of the outcome. Selected applicants are designated Astronaut Candidates and are assigned to the Astronaut Office at the Johnson Space Center (JSC) in Houston, Texas. The Astronaut Candidates undergo a training and evaluation period lasting approximately 2 years. During this time they will participate in the basic Astronaut Candidate training program, which is designated to develop the knowledge and skills required for formal mission training upon selection for a flight. Military Astronaut Candidates with a jet piloting background maintain proficiency in NASA aircraft during their candidate period.<br/><br/>As part of the Astronaut Candidate training program, candidates are required to complete military water survival before beginning their flying syllabus, and become SCUBA qualified to prepare them for spacewalk training. Consequently, all Astronaut Candidates are required to pass a swimming test during their first month of training. They must swim 3 lengths of a 25-meter pool without stopping, and then swim 3 lengths of the pool in a flight suit and tennis shoes with no time limit. They must also tread water continuously for 10 minutes wearing a flight suit. Candidates are also exposed to the problems associated with high (hyperbaric) and low (hypobaric) atmospheric pressures in the altitude chambers and learn to deal with emergencies associated with these conditions. In addition, Astronaut Candidates are given exposure to the microgravity of space flight during flights in a modified jet aircraft as it performs parabolic maneuvers that produce periods of weightlessness for about 20 seconds. The aircraft then returns to the original altitude and the sequence is repeated up to 40 times in a day. Final selection as an astronaut will depend upon satisfactory completion of the training and evaluation period. Graduation from the Astronaut Candidate Program will require successful<br/>completion of the following: International Space Station systems training, Extravehicular Activity skills training, Robotics skills training, Russian Language training, and aircraft flight readiness training. Civilian candidates who successfully complete the training and evaluation and are selected as astronauts become permanent Federal employees. Civilian candidates who are not selected as astronauts may be placed in other positions within NASA, depending upon agency requirements and workforce constraints at that time. Equal opportunity in employment means opportunity not just for some but for all. <br/><br/>#adventure <br/>#explore<br/>#space")
