Next up for Falcon 9 is launching 6 ORBCOMM ORB-2 commsats in one launch.

In November 11 more ORB-2 commsats fly on another Falcon 9.

Peter B. de Selding ‏@pbdes

Orbcomm CEO: Our SpaceX launch, of 1st six 2nd-gen sats, sched for April 30, after SpaceX NASA CRS. 11 remaining sats set for SpaceX in Nov.

Peter B. de Selding ‏@pbdes

Orbcomm: 17 2nd-gen sats to expnd mkt by 10x. New sats have 6x the receivers of 1st gen and 2x the speed. Add new protocol= 100x cpcty.

Peter B. de Selding ‏@pbdes

Orbcomm CEO: 6 new sats launching April on SpaceX shld give us near-trm rev boost of 'couple of million' as coverage hole is filed.

CRS-3 is on for March 16 and will try a landing at sea. It also has 4 landing legs. Check the reusable launcher and CRS-3 threads for pics of the legs and specifics.

@Rocketfox
Very awesome tonight to watch another F9 roll out of the building and start the trek to texas. See you on the other-side F9-10!

OG2 Mission 1 Update: April 11, 2014

A few weeks ago, Cape Canaveral Air Force Stations Range Safety experienced an issue with a primary launch vehicle tracking radar, which delayed the SpaceX Cargo Resupply Services (CRS) Mission originally scheduled for March 30. Range Safety has resolved that issue and is prepared to support the SpaceX CRS Mission on April 14. Due to the recent delays with the CRS mission, our new target launch window is May 10-15.

Looking at a May 17-25 launch.

Both F9 stages are at KSC.

I'm thinking this ORBCOMM launch will have a huge propellant margin, so returning to a point closer to KSC for another water landing test should be very possible.

Touching down within sight of the KSC tracking cameras would be PPV worthy :)

OG2 Mission 1 Update: April 18, 2014

Congratulations to SpaceX on a successful CRS launch this afternoon! ORBCOMM's OG2 Mission 1 is next on the SpaceX manifest. Sierra Nevada Corporation has four of our OG2 satellites packed, and they will be shipped to Cape Canaveral Air Force Station in Florida tomorrow, Saturday, April 19. The other two OG2 satellites will ship to Cape Canaveral next week in preparation for launch in mid-May. We anticipate setting a specific launch date with SpaceX by the middle of next week and will post that date asap. In the meantime, we are tracking the delivery of our satellites as they travel across the country to the Cape!

It seems that the payload weighs less than 1000 kg.

So yeah a very big propellant margin..... :-)

Launch has moved LEFT on the schedule

Only 22 days between CRS-3 and ORBCOMM, so they must be trying to make up the time lost by weather, NASA requested Dragon power upgrades and the KSC radar failure.

Launch Window: 9:39-10:33 a.m.

OG2 Mission 1 Update: May 6, 2014

Things are progressing well at the Cape. SpaceX conducted a flight readiness review yesterday and confirmed they are a “go” for May 10. Since then, the payload stack has been encapsulated by the fairing, and the entire stack is in the process of being attached to the rocket, which is expected to be completed late today. The next key step is the rocket being rolled out to the launch pad very early Thursday morning for the static test fire scheduled for mid-day Thursday. With a successful static test fire, we are on for a launch at 9:47 am ET on Saturday morning. Management expects to give an update and answer questions on the earnings call scheduled on Thursday, May 8, at 10:30 am ET.

Is there any info on how they are going to deploy the 6 separate satellites?

They are mounted on two ESPA (EELV Secondary Payload Adapter) rings made by Moog Industries.

Each ESPA ring holds 4 satellites, so on one there's 4 OG2's, and on the other is 2 OG2's and 2 mass simulators (for balance.) These rings get vertically stacked atop the F9 second stage and encased in a payload fairing (PLF).

After the PLF is jettisoned the second stage continues to burn until it's in orbit, then the engine shuts down. After a bit the second stage engine re-starts and does a circularization burn to make the orbit as perfect as possible, the engine shuts down, then it commands the ESPAs to begin deploying the OG2 satellites. Once that's completed the second stage turns 180°, the engine restarts a final time, it re-enters and burns up off SW Australia.

This fall F9 flies the ORBCOMM #2 mission, during which it will launch 11 more OG2 satellites. 3 ESPA rings on that one.

Do the satellites have propulsion? Why release 6 in the exact same orbit?

The ORBCOMM OG2 satellites do have propulsion and will be the first of a new constellation, with about 30 more launching as their older sats go out of service. It's a massive upgrade critical to ORBCOMM.

Like GPS, these sats are so numerous in each of several orbits, plus spares in case one of the primary sats in any orbit fail, so a few are always visible from almost anywhere. This allows the commercial message service packets they convey to be reliably relayed to ORBCOMMs numerous ground stations around the world.
