Put a satellite in a circular orbit about 42,000 kilometers from the center of the Earth and it will orbit once in 24 hours. Because that matches Earth's rotation period, it is known as a geosynchronous orbit. If that orbit is also in the plane of the equator, the satellite will hang in the sky over a fixed location in a geostationary orbit. As predicted in the 1940s by futurist Arthur C. Clarke, geostationary orbits are in common use for communication and weather satellites, a scenario now well-known to astroimagers. Deep images of the night sky made with telescopes that follow the stars can also pick up geostationary satellites glinting in sunlight still shining far above the Earth's surface. Because they all move with the Earth's rotation against the background of stars, the satellites leave trails that seem to follow a highway across the celestial landscape. The phenomenon was captured last month in this video showing several satellites in geostationary orbit crossing the famous Orion Nebula.

Since #Mars lacks a #magneticfield to protect a human base from the effects of the #solarwind, placing #TARS in geosynchronous orbit would produce an artificial magnetic field of protection for the dwellers there.

ULA-geo5 mission

Today, May 18,  at launch complex 41 of the Space Force compound at Cape Canaveral, Florida we were treated to the sight of the launch of the ULA (United Launch Alliance) Atlas V 421 rocket. The rocket, carrying the Lockhead Martin built SBIRS 5 (space based infer-red system) satellite and two smaller satellites equipped with the Ez3 and Ez4 flight systems. Lifted-off at 1:37 ET (10:37 PT). The launch was originally scheduled to take place the previous day but was delayed due to weather conditions.

The SBIRS satellite is the 5th installment of an array that will at its completion the array will be comprised of 6 satellites in a geosynchronous orbit over the Indian Ocean. The array will then provide the Space Force with warnings of incoming missiles and other critical information needed for the defense of the United States of America.

“Thank you to our mission partners for the tremendous teamwork as we processed and launched this asset that provides powerful surveillance and critical capabilities to protect our warfighters,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “We are proud to work with the U.S. Space Force to continue to meet the national security needs of our country.”

The EZ-3 & 4 satellites, that were a secondary payload, will provide critical information for launches and  capabilities for warfighters.

This launch marks the 87th time that the ULA has sent an Atlas V into space. Out of those 87 times this is only the 8th Atlas using the 421 configuration. The 421 configuration consist of a 13.7-ft long payload fairings on the centaur upper stage.

Can We Build That Here?

How long will we be building space systems that are (a) way bigger than they need to be and (b) completely customized for a single purpose? We are still operating on the mainframe computer model, lets see what a company is doing to change that model.

How long will we be building space systems that are (a) way bigger than they need to be and (b) completely customized for a single purpose? For comparison, we are still operating on the mainframe computer model, where computers ‘had’ to be the size of rooms. That didn’t last for computers, and it is just a matter of time before we transition to the desktop computer model of being able to just…

1965 - The First Transatlantic Television Signal from "Early Bird" Intelsat I

1965 - The First Transatlantic Television Signal from "Early Bird" Intelsat I #podcast #Technology #history

Intelsat I, a.k.a. Early Bird

1965 – Intelsat I, a.k.a. Early Bird, went into service. This geosynchronous satellite sent the first signal between nine different countries. A “One Hour TV Spectacular” was broadcast to Europe from the US, Canada, and Mexico.

Intelsat I went up in space on April 6, 1965 and had only 240 voice circuits, so it could only transmit one TV channel at a time. Early Bird…
