Fort Churchill (rocket Launch Site)
The Churchill Rocket Research Range is a Canadian former Spaceport, rocket launch site located outside Churchill, Manitoba. The facility was used by Canada and the United States beginning in 1954 for Sub-orbital spaceflight, sub-orbital launches of sounding rockets to study the upper atmosphere. The site was scientifically beneficial due to lying in the center of a zone containing high aurora activity. Over 3,500 sub-orbital flights were launched from the site. The site is sometimes referred to as Fort Churchill after the nearby former military base (now Churchill Airport) and is connected by an all-weather gravel road to the town of Churchill. History The complex was first built in 1954 by the Canadian Army's Defence Research and Development Canada, Defence Research Board to study the effects of polar aurora, auroras on long distance communications. The programme shut down in 1955, but the site was re-opened and greatly expanded in 1956 as part of Canada's participation in t ...

Landsat 7
Landsat 7 is the seventh satellite of the Landsat program. Launched on 15 April 1999, Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. The Landsat program is managed and operated by the United States Geological Survey, and data from Landsat 7 is collected and distributed by the USGS. The NASA WorldWind project allows 3D images from Landsat 7 and other sources to be freely navigated and viewed from any angle. The satellite's companion, Earth Observing-1, trailed by one minute and followed the same orbital characteristics, but in 2011 its fuel was depleted and EO-1's orbit began to degrade. Landsat 7 was built by Lockheed Martin Space Systems. In 2016, NASA announced it planned to attempt the first ever refueling of a live satellite by refueling Landsat 7 in 2020 with the OSAM-1 mission. However after multiple delays, NASA announced the cancellation of OSAM-1 in March 2024. The mission officially ended in 2 ...
