How Did we get the TV Transmission from Apollo 11

Here is a great video explaining how we in 1969 were able to see the TV transmission of the Apollo 11 mission:

WASHINGTON — Exos Aerospace flew its SARGE reusable sounding rocket for the second time March 2, but winds kept the rocket from achieving its planned altitude.

The Texas-based company launched the Suborbital Autonomous Rocket with Guidance, or SARGE, rocket from Spaceport America in New Mexico at about 12:45 p.m. Eastern time March 2. The launch had been scheduled for early January but postponed twice because of issues linked to the partial government shutdown.

The launch, called “Mission 1” by Exos, reflew the same rocket it launched from the spaceport on a “Pathfinder” mission in August 2018. The rocket carried several small research payloads and was intended to reach a peak altitude of 80 kilometers. The rocket, though, reached only a peak altitude of about 20 kilometers before gliding back to a landing about 1.2 kilometers from the launch pad.

John Quinn, chief operating officer of Exos, said in a later email that engine shut down when it hit a limit for instantaneous impact point (IIP) on its trajectory. The vehicle is designed to shut down its engine during ascent if it runs the risk of impacting outside a “safety circle” seven kilometers in radius around the launch site. That’s intended to protect the major buildings at Spaceport America, including the hangar for anchor tenant Virgin Galactic, that are 7.1 kilometers away, and lowers the company’s insurance costs.

The rocket’s control system wasn’t good enough to overcome high winds on ascent that threatened to push the instantaneous impact point outside the safety circle. “As the winds buffeted the rocket the gimbal correction was insufficient to keep it close enough to center of the circle to keep the IIP within the 7 km circle,” he wrote.

Despite missing its planned altitude, Quinn said the flight was otherwise successful. “This was a great test. Any flight where Exos and its payload customers can walk away with another set of data and an intact vehicle/payload makes for a good day.”

Exos says it will move into regular commercial operations of the SARGE vehicle, but didn’t state when their next launch would take place. The company also plans to use SARGE as the basis for an orbital launch vehicle called Jaguar able to place payloads weighing up to 100 kilograms into low Earth orbit.

Summer Engineering Expeditions

Come to Oregon State University’s Bend Oregon campus to design, build and launch rockets under beautiful clear skies.

This experimental learning program is perfect for high school juniors and seniors who are fascinated by science and want to explore what it’s like to be a rocket scientist or engineer.

Participants will work in teams to build and launch high-power rockets, will analyze the resulting data, hear from experts and learn from the best. math, physics, rocket engineering, geodesy, GIS and data analytics come together in one comprehensive project.

Skills gained at this immersive program will benefit participants as they head to college or technology jobs.

This is a selective program that requires a teacher recommendation. Rolling admissions through April 15th 2019.
