Title: SpaceX F9 : RCM RADARSAT Constellation : Vandenberg : NET November 2018
Post by: Chris Bergin on 07/30/2013 07:10 PM
Discussion Thread for RCM RADARSAT Constellation mission.

NSF Threads for RCM RADARSAT Constellation : Discussion (https://forum.nasaspaceflight.com/index.php?topic=32492.0)
NSF Articles for RCM RADARSAT Constellation :

NET November 2018 on reused Falcon 9 from Vandenberg.



[ Edit Oct. 23, 2017: Most of the references to this mission (http://www.asc-csa.gc.ca/eng/satellites/radarsat/default.asp) still have it launching in the second half of 2018.  Except for that one comment from DLR (http://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-23370/#/gallery/27659) that they were calibrating the transponders leading up to launch in 2019.  The mass is generally listed as about 1400kg (total?), except for that one (http://www.asc-csa.gc.ca/pdf/eng/publications/radarsat-constellation-eng.pdf) saying it's 1600kg. ]

Very short presser, so beefed it up with the history etc.

What exactly does "reservation contract" mean?  I don't recall seeing that language in other recent announcements. Is it different than an "agreement to launch?"

It's like a MOU. Clearly customers want to see this new rocket have some successes before putting money down.

Now that I'm posting on the correct thread...

A great win-win day for Canada & SpaceX. Too cool. Congrats.

And this holds hope for even more good news for both Canada's space industry, and SpaceX's manifest:

"While the baseline mission for this evolution in Canada’s Earth Observation capability revolves around three satellites, the constellation is designed to be scalable to six satellites."

In the correct forum...

Does SpaceX have a suitable standard multiple payload dispenser in development or will a one off hardware solution for deploying three satellites  need to be devised for this mission?

They should gain experience and hardware with the up coming Orbcomm and Iridium launches. Both will involve multiple launches with multiple payload adapters.

SpaceX have a deal with Spaceflight Inc. to supply a Seconday Payload System for the Falcon 9, but this I believe is for small secondary sats only. Whether they will outsource the payload dispenser for this mission as well is anyone's guess.

Presumably something is in development as they have two dual GEO satellite launches scheduled for circa 2014-2015 on F9,  SpaceX Signs Launch Agreements with Asia Broadcast Satellite and Satmex (http://forum.nasaspaceflight.com/index.php?topic=28328.0):

Together with Satmex, our co-launch partner, we embark upon an innovative prospect of dual launching four medium-powered satellites on two launches on the Falcon 9.

No dual adapter is needed for those spacecraft.  They are made to stack on each other

A few days ago, the RCM mission has disappeared from the SpaceX launch manifest website (http://www.spacex.com/missions).

Just a web site mistake or was the launch contract (or even the RCM mission itself) cancelled?

Is there an argument for changing the thread title, as presumably this will not be on a v1.1 but a FT?

Als per request of SpaceX, it should simply be Falcon9 of F9 for short.  After Jason3 there is only one version.

Edit: not sure about short F9 part, but seems logical

Not likely to be Block 4 in the second half of 2018.

Screen grabs. The dispenser firsts tilts the satellites and then separates them. Ruag have had 100% success with their adaptors.

I'm wondering a bit about the mass of the sats which is in some sources as well as in this Thread specified with ~475kg.

At the CSA website the "Total mass at launch" is given with 1602kg. And the sats are based on the Canadian SmallSat Bus which has a mass of 760kg only for the bus...

1602kg per sat would give around 4800kg for all three which make a F9 launch more logical than an F9 launch with a payload weight less than 1500kg in total.

https://directory.eoportal.org/web/eoportal/satellite-missions/r/rcm

It looks to me like the mass of each satellite is around 1400 kg. This is just based on web searches and trying to interpret various presentations etc. There is one very old CBC article that seems to suggest 1200 kg/sat more definitively (i.e., vs total launch mass for all three: http://www.cbc.ca/news/canada/mda-awarded-contract-to-design-satellite-fleet-1.721135). Most sources just list a mass without mentioning per sat or not... but generally they are comparing Radarsat 1, 2, and now RCM... seems most logical to me to compare the individual satellites, but hard to say really, because when comparing something like revisit time, they will often say daily, but that is for the constellation...

Just read this link more thoroughly, originally posted by rocket-chris. It seems rather specific that the mass is 1400 kg/spacecraft and also specifies the bus mass and payload mass separately, both of which mass more than the 475 kg figure that has also been mentioned. Search for "mass" on the page.

Over 3 metric tons rolled away from our #Linköping facility,

Looks like it's 1400 kg per spacecraft plus the dispenser.  I'm guessing that means this mission will lift probably between 6200 and 8200 kg (depending on how much of that 3 metric tons is the payload adapter).

Attended a presentation by Daniel De Lisle (CSA) on June 6 where he stated that the current "focus date" for launch is November 7th, one week into the contracted one month launch period. Should be able to at least say NET November.
