Due to storage considerations on the International Space Station, the two surplus Orlan space suits in storage on the International Space Station were discarded via the Progress Cargo Vessel. One of these suits was to be used to house the electronics for the upcoming SuitSat-2 mission where the batteries were to be mounted inside the suit, solar panels attached to the extremities with the electronics, video cameras and antenna mounted on the helmet by the ISS crew prior to deployment during an EVA.
The Progress, with the suits included, was undocked from ISS this past week.
The ARISS International Team has been informed that there is still space available for shipment of the SuitSat-2 electronics on the projected cargo flight to the Space Station in January 2010 and the EVA scheduled for April 2010 still has a 'SuitSat-2' deployment scheduled.
Consequently, the AMSAT team developing SuitSat-2 electronics on behalf of ARISS International is focusing on completing development in anticipation that deployment will still take place in Spring 2010 using a new structure to house it. In addition, the experiment being developed by Russia's Kursk State University is still expected to be integrated into the electronics once the US produced equipment is delivered to Russia this fall. Discussions are currently taking place between Russian ARISS members and the AMSAT project managers concerning the design of the new structure and where it will be constructed with these decisions to be made in the next few weeks.
The AMSAT team building the electronics is meeting July 10-12 in Phoenix to initiate integration testing of all of the components built in the US with subsequent testing to continue through the remainder of the summer in anticipation of shipping equipment to Russia in the fall.
The removal of the Orlan space suits from ISS removes the 'Suit' component of this deployment and at some point a new project name will be used to reflect the change in configuration. However, the significant importance of this project to both ARISS and AMSAT is not diminished.
ARISS sees this mission as an important component of education out- reach as it will provide an opportunity for students around the world to listen for recorded greetings from space as well as learn about tracking spacecraft in orbit.
Meanwhile, the deployment of SDX (Software Defined Transponder), the associated receiver and transmitter modules, and control electronics is a critical milestone for AMSAT as this upcoming flight provides an opportunity to flight test the next generation of spacecraft hardware. Lessons learned from this deployment will be applied to future flight opportunities as AMSAT moves towards a 'modularization approach' to spacecraft development with the expectation the future spacecraft missions will utilize a derivative of SDX and the associated hardware.

Just for grins...with the reduced gravity at 200 miles up..how much force would need to be applied "vertically" (in reality 'away from the earth") for a cubesat to arrive in an orbit which would last significantly longer without additional propulsion?
Background...I was a business major so such calculations ARE rocket science to me...

Now, that is an intriguing thought Roger !
I think to get maximum altitude you would need to 'throw' the satellite forward. i.e. in the direction of movement of the ISS. This would give you an elliptical orbit with the lowest point at the starting altitude and the apogee or highest point determined by the amount of delta V applied when the satellite was thrown.
So.....1) What orbit do you get if the original direction of travel is "vertical" or 90 degrees to the direction of travel? ???????? 2) How to convert the ability to throw a 1kg brick 25 feet into the air on earth, into a figure of Newton seconds to calculate thrust and delta V for orbital change.
Thanks
David

Actually, on a serious note. Although this announcement generates a huge amount of work for those involved in xxxxSat2, it will result in a package with higher density which will last longer before reaching the atmosphere. Looks like the late nights at Pheonix.
