DirecTV satellite may explode in orbit

Posted by Orange Blossom Special on Fri Jan 24 15:13:53 2020

CNN will blame Trump.

A large broadcast satellite — owned by AT&T’s DirecTV, built by Boeing and operated by Intelsat — suffered major damage to its batteries in December and is now at risk of exploding.

DirecTV disclosed the issue in a special request to the Federal Communications Commission this week, asking for permission to remove its Spaceway-1 satellite from orbit.

“Spaceway-1 suffered a major anomaly that resulted in significant and irreversible thermal damage to its batteries,” DirecTV said in the filing. “There is a significant risk that these battery cells could burst.”

The satellite is notably several years beyond its intended lifespan. Launched in 2005, Spaceway-1 is a Boeing 702-model satellite, a build that is typically expected to last 12 years.

“The battery malfunction occurred in the course of beyond-contract-life operation after a collection of events that have a very low likelihood of occurring on other satellites,” Boeing said in a statement to CNBC.

Looking at ATT's customer service and operations, this doesn't seem to shock me.

Why does the space force wear camouflaged uniforms?

Looks like they may have to give it the FR3 treatment....shoot it out into space utilizing the positioning “rockets”.....FR3 was a a C band TV sat that had one that stuck as they sought to get in place (this was the late 70s-early 80s) and became lost. They did find it, if was repeating RF emanating from Jupiter until it crashed into the planet. They won't let it explode before they do something like that, it’s a crowded space and explosions create shockwaves that will disrupt other birds up there. Not that big a deal, these things ARE insured....

because so does the air force, and they haven't made new uniforms yet...

It was an evolution of the logo of the Air Force Space Command, what the Space Force was before it got promoted.

"Additionally, the satellite should discharge its remaining fuel, the company said, “to reduce the risk of accidental explosion.”"

Is it high enough in orbit they can let it burn up on reentry?

That’s the thing, it will never reenter. Geo-stationary and Geo-synchronous satellites are pushed about 300km higher into super-synchronous (orbit takes longer than one solar day) graveyard orbit. They don’t have enough fuel for a full retrograde thruster burn to bring the low point in the orbit to a point where the atmospheric drag will pull it down.

De-orbit requires 1500 meters per second change in speed (this change is speed is know as “Delta-V”). The graveyard orbit only requires 11 meters per second, spent in two bursts (one to push the top of the orbit higher, the other to “circularize” the orbit when it gets there.
