Space Shuttle program: STS-36 (Space Shuttle Atlantis) US 65th manned space mission returns from space

The Space Shuttle program: STS-36 (Space Shuttle Atlantis) U.S. 65th manned space mission returns from space on March 4th, 1990, marks a significant milestone in human space exploration. This successful mission, carried out by the Space Shuttle Atlantis, contributed valuable research and insights into various scientific and technological fields. Let’s delve into the details of this historic event and its significance in shaping our understanding of space.

The STS-36 mission was the 27th mission of the Space Shuttle Atlantis and the first classified Department of Defense (DoD) mission after the Challenger disaster in 1986. The launch took place from the Kennedy Space Center in Florida on February 28th, 1990. The crew comprised five astronauts, commanded by John O. Creighton.

One of the main objectives of the STS-36 mission was the deployment of a classified payload for the U.S. Department of Defense, which involved gathering data related to defense and intelligence operations. Although the specifics of the payload’s purpose and capabilities remain classified, it is believed to have included reconnaissance equipment and sensors.

Apart from the classified payload, the mission also conducted several scientific experiments and tests. One of the notable experiments involved the investigation of the growth of protein and semiconductor crystals in microgravity. This research aimed at understanding the impact of the space environment on crystal growth, which could contribute to advancements in various industries, including medicine and electronics.

Another experiment focused on understanding the physiological effects of space travel on the human body. Astronauts onboard the Atlantis underwent medical tests to measure changes in their cardiovascular, respiratory, and musculoskeletal systems. These findings were crucial for understanding the long-term effects of space travel on human health and developing countermeasures to mitigate those effects.

The STS-36 mission also involved the release and retrieval of the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer (ORFEUS) satellite. ORFEUS, developed by Germany’s space agency, aimed to study the extreme ultraviolet radiation emitted by stars. The data collected by ORFEUS provided valuable insights into the evolution of stars and galaxies, contributing to our understanding of the universe.

After completing its mission objectives, the Space Shuttle Atlantis re-entered the Earth’s atmosphere on March 4th, 1990, successfully concluding the STS-36 mission. The mission lasted a total of 4 days, 10 hours, 18 minutes, and 47 seconds, covering approximately 1.7 million miles.

The significance of the STS-36 mission extends beyond the specific objectives it achieved. This mission marked the successful recovery and rebuilding of the Space Shuttle program following the tragic Challenger accident in 1986. It instilled renewed confidence in the shuttle’s reliability and paved the way for future space exploration endeavors.

Moreover, the STS-36 mission showcased the versatility of the Space Shuttle Atlantis by combining classified military operations with civilian scientific research. It demonstrated the shuttle’s ability to serve multiple purposes, solidifying its position as a critical asset in advancing both national security and scientific understanding.

the STS-36 mission of the Space Shuttle Atlantis on March 4th, 1990, was a significant milestone in human space exploration. It successfully accomplished classified Department of Defense objectives, conducted important scientific experiments, and contributed to our understanding of space and its impact on various fields. The mission’s success not only advanced scientific research but also demonstrated the resilience and adaptability of the Space Shuttle program following the Challenger disaster. The STS-36 mission stands as a testament to human ingenuity and determination in the pursuit of knowledge.
