Rideshare missions to GTO, only $14 million for Eagle, $800K for 3U Cubesat
Spaceflight Services Announces Lunar and GTO Mission Pricing
Prague, CZ - September 30, 2010: Spaceflight Services (Spaceflight) announced today pricing for small payloads to Geosynchronous Transfer Orbit (GTO) and Low Lunar Orbit (LLO).
Spaceflight, as part of the Rocket City Space Pioneer Google Lunar X-Prize Team, is responsible for mission integration and providing space transportation services to Low Lunar Orbit. Spaceflight is providing flight opportunities for ESPA class spacecraft (spacecraft weighing less than 180 kg) interested in launch services to GTO and Low Lunar Orbit.
The proposed mission, which is slated for Q4 2013 or Q1 2014, will deploy three ESPA payloads into a Geosynchronous Transfer Orbit and two additional payloads in a Low Lunar Orbit. The mission is also open to smaller spacecraft looking for a low cost ride to either of these destinations.
Mission pricing for small payloads to GTO begins at $795,000 for a 3U CubeSat and up to $13,950,000 for a full ESPA spacecraft.
------------------------------------------------------------
This is considered a "Low Cost Ride" in the commercial world. This is the free market value of the launch that we are hoping to get for significantly less. Wish us luck...

I certainly wish the best of luck with finding a cheap ride! Aside from being GTO, I do not consider their offer to be a good deal at all, since: (1) Their prices are set so that they can finance their own lunar mission (2) The price for a whole Falcon 1 is $11M, which will take 1 metric ton to LEO. (3) Even for a Falcon 9, the price seems to be less than $10M for 1,600 kg to GTO, see http://www.spacex.com/falcon9.php#pricing_and_performance

Think of these prices as 'retail' costs. Spaceflight Services aims to provide their customers with a guaranteed ride, and deal with dividing up the payload space, weight, etc. As such, they will certainly be more expensive than the 'wholesale' costs you list above.
While this service might not ever be right for Amsat, it does, I think, show that Amsat's current focus on Cubesat-level miniaturization through the Fox platform (and AMSAT-UK's work with FUNcube) is the path forward for both LEO *and* HEO. Here is a GTO opportunity that is an order of magnitude less costly than others we have recently been aware of, and at retail costs. Obviously there are a whole host of challenges that would need to be met, but if GTO is opening up to 3U and similar configurations, and at a price that we could even imagine being able to fund, then it's great we're moving aggressively into that platform.

Did anyone manage to bag any contacts off A040 before it's sad event?
I believe I did- What dates and times are you looking for?

I was on AO-40 from its launch, initially running mode US, then mode LS (I bought one of the few DEMI 1268/144 Tx converters that were made). I made several contacts after I got my s-band downlink working. Initially, I was using too small an antenna and did not have a decent preamp. Once I graduated to the 85cm (33-inch) offsst feed dish and added a MKU-232 preamp, I was able to hear anyone. I spent a long time collecting telemetry and could do so out to a squint angle of 49-degrees.
It really is a shame that there was no workaround for the battery issue or even run on solar panels like AO7. But this was before AO7 reawakened to provide that insight. I lived and waited long years for AO-40 and unfortunately wasted time I could have operated on AO-13.
Now I have all the stuff needed to work a Heo and hardly anywhere to use it (I bought one of the early FT-847 just for AO-40). I would say a lot of the operators of the Heo years have gone away from satellite activity (some remain lurking on Amsat-bb wishing upon a star ...or a hope and a prayer).
I will return, if Murphy will leave me alone long enough! But I mainly operate Oscar-Zero now days.

I didn't have a base satellite station when AO-40 was launched, and still don't have one now (really no need). However, it was amazing to copy AO-40's 2 meter telemetry when it was at apogee with just a simple 2 meter all mode rig, a 7 element beam pointed at the right diorection (no elevation control), no pre-amp and 45 feet of lossy RG-58 coax. At times it was a true S-4 on the meter. Since my antenna was linearly polarized, vertical, I could watch the signal dip a little as the bird was spinning.

My last logged contact on AO-41 was 8/13/2004 with W7ARO. My last logged DX contact on AO-41 was 8/12/2003 with FM5CS. I am sure there were other contacts that did not get logged.

I made over 1300 contacts on AO-40 during its 2 3/4 years of operation.
The first QSO was on 05/05/01 at 08:17 with Mike N1JEZ on U/S then at 08:39 worked Dom I8CVS, at 08:52 Fred CU8AO, and at 09:03 Frank DL6DBN.
I then fired up my FT-736R on 1.2 GHz and at 09:44 worked Steve KB8VAO with both of us making our 1st L/S QSO on AO-40 and then at 09:55 worked Mike N1JEZ for his first L/S contact.
On the 25th and 26th of Jan 2003 an AO-40 QSO party was held. 30 logs were submitted from 14 countries. I made 107 QSO's with 19 DXCC countries.
My last contact was on 28/01/04 at 20:39 with DG4DW. My next log entry was at 29/01/04 at 01:35 with Jerry W0SAT and my log note is "we talked about AO-40 gone"
In spite of the fact AO-40 had major problems and never operated near it's original design I think it was a very successful amateur satellite.
Bob (W7LRD); I guess all we can do now is remember the good old days and cry on each others shoulders. SOB SOB

I never made any contacts via AO-40. I was still preparing my station... I was busy being happy about my MIR packet contact... (I made the ANS one time) I still have a couple K5GNA downconverters... with the filter kits (as yet uninstalled) If we could get another in orbit I could use this stuff again... Ive been waiting a long time... Im sorta giving up on the project.. .so much $ and no results.. we really could use a HEO sat... I would be back.. I still show the kids the keps and the signs.. but with only 5 minutes to make a contact amongst a crowd im just shoved out of the way.. .
Will we ever see another HEO sat??

I had some fun on AO-40, and made some contacts. I hope to get them on LOTW before summer.
I had problems getting enough uplink signal. I could hear everyone (including myself) just fine, but a lot of folks had trouble hearing me. Then I would check the telemetry and see the AGC on the bird was driven 10 dB or so!!!
They were good days!

It's really not that bad. On HO-68 or AO-7 you get at least 3x that time. FO-29 varies, but it also provides quite a bit of time. And there's a distinct lack of a 'crowd' on the linear birds. Even on VO-52 you can have a nice conversation because you can hear horizon-to-horizon.
The LEO scene is a different set of challenges, but they can be fun to overcome, and the same kids who are interested in the keps will *really* love to hear their own voice bouncing off of VO-52 :-)
Will we ever see another HEO sat??
As I see it, there is good news and bad news in this. For years, the bad news was that rides to space have become so commercialized that 'we' can't get freebies or ultra-cheapies anymore, and we simply can't afford to pay the proper price.
The good news, only recently, is that this commercialization is starting to provide full-cost opportunities that might be within our financial range. But these would require us to perfect many aspects of cubesat-level miniaturization, and would require much more advanced ground stations.
Of course, if some inexpensive opportunity arises, the AMSAT-DL P3E satellite is available.
73, Bruce
by the way... I for one have absolutely no interest in FM... completely misses the challenge IMO...

My most challenging contacts were made using K band (24 GHz down). First contact was on 4/20/2002 with Jerry, K5OE.

I think the only mode I never got to try was 2.4 GHz up. I have the transverter sitting here in my shack, but AO-40 went bang before I got to use it. The plan was S/k.

Hi Mike, N1JEZ
You should remember that you and I and Charles G3WDG we partecipated to the only one test made on 2.4 GHz up and 24 GHz down i.e. mode S1/K on AO40 on day 02/23/2003 and I was received on 24 GHz both by you and by G3WDG.
I still have your CD diskette made by you and sent to me with the record of my 24 GHz signal received by you in Burlington VT
Unfortunately at that time I was not ready to receive on 24 GHz but I was only able to transmit on 2.4 GHz with 10 watt at a 4 feet prime focus dish.
Unfortunately for that experiment scheduled by AMSAT and command station Stacey Mills W4SM only three stations where active i.e G3WDG, N1JEZ and my self ,i8CVS
G3DWG was equipped to transmit on 2.4 GHz and to receive on 24 GHz so that only he was able to get back his own signal from the transponder.
You where only able to receive on 24 GHz but not to transmit on 2.4 GHz so that you where able only to copy G3WDG and i8CVS on 24 GHz
I was able only to transmit on 2.4 GHz but not to receive on 24 GHz so that at the end of the experiment no two way QSO S1/K was possible to made between us but most important the experiment demonstrated that the S1 2.4 GHz receiver on board of AO40 was working and was alive and well !
Those were really fun days Mike !

Hi Domenico,
I do not think that this has been the only 24 GHz experiment on AO-40. You can find audio recordings of the 24 GHz signals of DK1KQ and DB6NT on my website www.dd1us.de in the sounds from space collection. I will be happy to add your signals too if you want to provide me a copy of the recording.

Hi Matthias, DD1US
The experiment to transmit to AO40 using a 2400 MHz uplink and a 24 GHz downlink i.e the mode S1/K was made only ONE TIME and never was repeated and it was skeduled by command station W4SM to check if the onboard 2400 MHz S1 receiver was working or not.
There are many other 24 GHz downlink QSO's but they where all made using the 1.2 GHz uplink i.e. using the mode L/K
Charlie G3WDG has the record of the above unique S1/K test and you can get a copy from him.
By the way if I will be able to find the above WAV file in my PC I will send it to you for your record.
I actually have on hand only the CD diskette of my signal on 24 GHz for the above S1/K test as received in USA by Mike N1JEZ
Here is copy of the original text of the message sent by W4SM on AMSAT-BB on day february 23 2003 after the succesfull experiment. -----------------------------------------------
Two tests were performed on AO-40 today.
The first was a long shot and involved listening for the S1 transmitter exciter stage using Günter Wertich's EME dish. Nothing was heard during a 20 MA window of testing in which the S1 Tx was connected to the middle beacon.
The second test involving the S-band receivers was completely successful. Extremely strong downlink signals were possible using S-band uplink to K-band downlink. Charlie (G3WDG) phoned me and I heard beautiful downlink signals from his ~5 watt uplink to S1. S2 was also active, but because of its higher, less common frequency (2446 MHz), it may not have been tested. The S1 Rx uses the S1 Tx high-gain dish, and the S2 Rx uses the 5 turn helix used by the S2 Tx, so signals would not be as strong through S2 at low squint. More information will undoubtedly be posted on this by the participants, but special thanks to Charlie (G3WDG), Mike (N1JEZ), and Dom (I8CVS), and any others who participated in this successful test.
The S1 Rx can certainly be listed as fully functional. We will await further testing/info. on the S2 Rx.

I was able only to transmit on 2.4 GHz but not to receive on 24 GHz so that at the end of the experiment no two way QSO S1/K was possible to made between us but most important the experiment demonstrated that the S1 2.4 GHz receiver on board of AO40 was working and was alive and well !
Those were really fun days Mike !

Hi,
thanks for the various feedback and multiple audio recordings, especially from Domenico, John and Mike.
Domenico, thanks for pointing out that the experiment you were referring to was the only S1/KU band experiment. Indeed the other recordings from the KU band downlink, which I have provided in the "Sounds from Space" collection, are indeed based on the L-band uplink.
Best regards

Hi Domenico,
I do not think that this has been the only 24 GHz experiment on AO-40. You can find audio recordings of the 24 GHz signals of DK1KQ and DB6NT on my website www.dd1us.de in the sounds from space collection. I will be happy to add your signals too if you want to provide me a copy of the recording.
Best regards

Those were fun days Clare!
My most challenging contacts were made using K band (24 GHz down). First contact was on 4/20/2002 with Jerry, K5OE.

I think the only mode I never got to try was 2.4 GHz up. I have the transverter sitting here in my shack, but AO-40 went bang before I got to use it. The plan was S/k.

Hi Mike, N1JEZ
You should remember that you and I and Charles G3WDG we partecipated to the only one test made on 2.4 GHz up and 24 GHz down i.e. mode S1/K on AO40 on day 02/23/2003 and I was received on 24 GHz both by you and by G3WDG.
I still have your CD diskette made by you and sent to me with the record of my 24 GHz signal received by you in Burlington VT
Unfortunately at that time I was not ready to receive on 24 GHz but I was only able to transmit on 2.4 GHz with 10 watt at a 4 feet prime focus dish.
Unfortunately for that experiment scheduled by AMSAT and command station Stacey Mills W4SM only three stations where active i.e G3WDG, N1JEZ and my self ,i8CVS

Many, many,
I particularly loved the qs I had from the Virgin Islands to Japan at the end of AO40's life. I had a morning window twice a week and ran less than 10 w. up into my 44 el. yagi and downlinked on 2.4ghz. Real pile ups. Many qsls - all answered.

The interesting question is is how much will AMSAT members be willing to invest in ground stations. A 3U cubesat could provide a HEO satellite similar to Arsene (AO-24).
