IIRC flights out of VAFB have such telemetry drop outs once in a while (e.g. some of the Delta II flights I watched), but for this one the wait certainly seemed to be longer.  :-X

First contact will be when the Satellites loop around the Earth and pass over Alaska:

To be exact, AOS will be via the Alaska Satellite Facility at University of Alaska Fairbanks (https://www.asf.alaska.edu/). Planet and Terra Bella have equipment located on site.

How bizarre they canít maintain telemetry over the horizon and we just have a simulation.
TDRS is expensive, and so are floating ground stations.  If the mission doesn't require it, no need charging the customer for service they don't need.

Maybe Iíve missed something but I donít remember any such issues with any recent Space X, ULA and even other Orbital launches.

I believe those are equipped with TDRS transmitters. And with the Minotaur-C being a low-cost launcher, it doesn't have a TDRS transmitter.

According to the latest users guide that I have on my computer, TDRS is provided as an optional service.

That philosophy is fine right up until there is a problem with the launch. Then you wish you had the telemetry since knowing when the problem occurred and other information before the anomaly is a big help in working out what the problem is. Without the telemetry you are working completely in the dark.

Quick update:

AOS of the SkySat and Flock satellites should occur in about three minutes.
Because the Falcon Heavy Test Flight was successful, it has inspired thousands of people to consider changing the future of space travel.

Have AOS of the satellites occurred yet?

We don't know. I'm watching the OA and Planet Labs twitter accounts, but there has been no updates. Contact should have occurred by now though.

Telemetry on sun-synchronous missions out of VAFB is a real problem for solid-fueled vehicles relatively early in flight. The TM antennas are looking almost straight up the rocket's tailpipe, and remember that solid fuel contains a lot of aluminum. It's like a fighter dispensing chaff to throw off a radar guided missile.

2.5 miles from the launch site. 

We canít pick up the remote cameras due to the ongoing fire around the pad.

The helicopter w/ water bucket did went over the pad within few minutes after the launch. However 2 hours have passed and still didnít get ďAll ClearĒ signal yet.

Shots of the Minotaur-C launch from the western foothills of the Santa Ynez Mountains on South Vandenberg, one of the few areas with direct visibility to the pad from 8.1 miles away. In the frames can be seen two of the tracking radars as well as the offshore patrol boat enforcing the closed sea area. Other observation locations were slightly closer, but with obscured view as area 576E is down the shoreward slope of the Burton Mesa which makes up a large portion of North Vandenberg. This elevated hillside viewpoint provided a unique perspective of today's launch.

FOR IMMEDIATE RELEASE

From: 30th Space Wing Public Affairs, www.vandenberg.af.mil



Vandenberg Launches a Minotaur-C Rocket



VANDENBERG AIR FORCE BASE, Calif. -  The Orbital ATK Minotaur-C rocket,
carrying 10 small satellites owned by Planet, launched from Space Launch
Complex 576-E here Tuesday, Oct. 31, at 2:37 p.m. PDT.



Col. Greg Wood, 30th Space Wing vice commander, was the space launch
commander.



"This launch was an incredible achievement for Team Vandenberg, Orbital ATK,
and our other launch partners," said Wood. "This Minotaur-C launch marked
the first at Vandenberg in six years and I am very proud of the teamwork
that led to this successful launch. The hard work and dedication of everyone
involved continues to ensure our nation's access to space."
