Problems with OBC startup issue resolved
Matthew Ashworth and Andrew White travelled from Portsmouth to the Lunchsat lab in Stevenage to work alongside the OBC and Imager teams to identify the power regulator at the root of the problem. A replacement has now been ordered, alongside a new power surge protector and fixed voltage power supply, for installation next week -- when further testing will take place to ensure the problem is not being caused by other subsystems and that the new equipment minimises stress on the new regulator.
More satellite design work and testing hours will be required over February to ensure the project remains on schedule. Results of hardware testing are to be published in advance of the upcoming Review sessions, to be held with technical experts and senior management.
The OBC startup issue should be resolved by early February. The Mid-Term Review with technical experts is scheduled for early March; the End-of-Year Review with management is set to conclude progress mid-June.

Lunchsat documentation now standardised

Having first designed a new document template for all Lunchsat documentation based on the Astrium corporate guidelines, members of the System subsystem team proceeded to design the new handling system, headed up by subsystem lead Graham Johnson.
Fatou Mbaye has drafted a unique reference system of document identification codes which is now in immediate effect. Newly configured documents are stored in the Lunchsat Portal, an internal collaboration environment for the sharing of knowledge and information on the Lunchsat project.

First Space Systems lecture a success
Members of both teams enthusiastically engaged with the speaker of the first topic 'On-Board Computing for Spacecraft', which promoted awareness of computational requirements not just for a microsatellite such as Lunchsat, but also for spacecraft in general.
Space places limitations on electronics technology in terms of mass, power and volume as the harsh environment applies mechanical and thermal stress to spacecraft components. Radiation from space is a major consideration for software, as ionization can flip the bits in binary code which could result in the failure of the OBC and other electronic devices. The damaging effects of this radiation can be mitigated by heavy shielding of the OBC inside the spacecraft. Striking the right balance is a tricky affair: faster processors can become hotter by consuming more power, whereby smaller ones are more susceptible to the effects of radiation.
The lecture went on to present examples of on-board processing currently being developed -- including the data management, payload data handling and visual processing units of the Gaia spacecraft, which aims to survey a billion stars in five years.

Space Systems lecture series begins
These internal lectures, part of the Space Systems series for Lunchsat and Campus Management, aims to connect the two teams with experts in the field to supplement graduate training and facilitate knowledge transfer between the two graduate initiatives.
The lunchtime sessions are to occur for both teams on the second Thursday of each month from now until July, 13:00 - 13:30 with each aiming to cover one of seven topics about space system engineering, the basic foundation for microsatellite development.
The schedule is set to cover the OBC and Software (January), Mechanical (February), Antennas and RF (March), Payload (April), Thermal (May), Propulsion (June) and ADCS (July).

Project lead reflects on 2009 progress
In an email to all 43 members of the Lunchsat team, Nick gave his congratulations and 'thanks for all the hard work over the last few months'.
"The project is coming along well with real results, such as Systems producing an updated release of the Payload Interface Document which will be critical for getting new payloads and all subsystems have made good advances. On the hardware side, we have power tests ready to go and work planned on both groundstations.
"Due to the feedback from last year, we are communicating better with experts inside and outside the company (such as the Bepi Project Manager, AMSAT, Queen Mary Uni) and the blog is going and we are being tweeted about by Clyde Space [a large Cubesat company in Scotland].
"There have been some setbacks but that is normal for any programme no matter the size and so we should take this as an opportunity to show that we can overcome and solve such problems. We have a plan in place to solve the OBC power-up issue and this will be the highest priority in the New Year."

Subsystem leads are to supervise the extension of subsystem work package descriptions for completion by February; descriptions for each are to be released on our website pages to assist in the definition of each subsystem.
Those involved are Nick Fishwick (Project Management and Power), Stephen Pulker (On-Board Computer and Imager), Natasha Pushkin (Thermal and ADCS), Alex Buick (Operations and Payload), Jason Stones (Media and Communications), Fatou Mbaye (Systems and Mechanical) and Nicolas Sarda (Groundstations).
The focus team also arrived at a complete schedule that defines Lunchsat activity from present to the future launch. Three work packages are to be defined per subsystem for assignment to each of the three Lunchsat phases that have since been defined (1-3); these are detailed in turn (A-E):
Phase 1: Design and Analysis, October 2009 to September 2010
Phase 2: Testing and Pre-Launch, October 2010 to December 2011
Phase 3: Launch and Operations, 2012
Phase A: Detailed Definition, Manufacturing and Testing (GDP Year 1), October 2009 to August 2010
Phase B: Detailed Definition, Manufacturing and Testing (GDP Year 2), October 2010 to June 2011
Phase C: System Level Integration and Testing, July to December 2011
Phase D: Pre-Launch Activities and Launch, January to June 2012
Phase E: In-Orbit Commissioning and Operations, July to December 2012
The Lunchsat website now features details of our complete schedule.

Operations and launch: two giant leaps for Lunchsat

In having commissioned a new Operations subsystem to handle the management of post-launch attitude and maintenance of our nanosatellite, the next step in getting Lunchsat into space is to prepare it for launch readiness!
Representatives from the new Operations subsystem and key subsystem leads met this morning in a videoconference between Astrium's Stevenage and Portsmouth sites to discuss the next major stage in the Lunchsat project – launch. Present at the meeting were Alex Buick (Operations), Fatou Mbaye (Systems), Jason Stones (Media), Stephen Pulker (Project Management, OBC) and Natasha Pushkin (Thermal), alongside project manager Nick Fishwick and project champion Ronan Wall.
Over the next month, this team will compile a comprehensive report to present to Astrium management, detailing the options available in four possible launch scenarios. As such, the report is to address the available launchers and options for the Lunchsat payload, forecasted schedules, prospective team involvement and the budget allocations required to support each option. These areas are to be defined in the four separate scenarios foreseeing launch within one year; three years with Pathfinder; three years without Pathfinder; and five years, respectively. 'Not launching is not an option', emphasised project lead Nick Fishwick.
It is currently envisaged for Lunchsat to become flight-ready sometime in 2011 post-testing, in order to piggyback on a ride with the Lisa Pathfinder when the space science mission is launched into space on an Ariane 5 rocket in 2012. This is deemed a strong possibility – particularly given both the financial infeasibility to use a dedicated launcher, and the potential compatibility of the Pathfinder launch window with Lunchsat as a Cubesat, as the payloads of previously launched Cubesats have taken between 9 months and two years to build.
The Operations focus group aims to compare the parameters of our Lunchsat mission with those of others – Aeolus, KaSAT, Astra 1M, Hylas and ExoMars – by liaising with their project managers to assess the true logistics of launch.
Additionally, the report aims to assess the prospective advantageous outputs from Lunchsat once the nanosatellite is launched. These include strengthened public relations through enhanced visibility between Astrium and the wider community, the establishment of Operations training to maintain the satellite in orbit, lessons learned from our first attempt and accelerated technology development in collaboration with our partners in the wider Cubesat Research Network (CRN), if work begins on a second Lunchsat nanosatellite in the longer-term.
As part of Operations requirements, we have entered the process of researching possible worldwide launch sites and configuration scenarios. As Lunchsat will be launched into equatorial orbit, feasible spaceports include Cape Canaveral Air Force Station in Florida (NASA), Guyana Space Centre in Kourou, French Guyana (ESA), Baikonur Cosmodrome in Kazakhstan (RKA) and the Yoshinobu Launch Complex at Tanegashima, Japan (JAXA), among others.
A review of cost assessment and related contacts for launch scenarios at each of these sites will be included in the Lunchsat Launch Report, to be released in the New Year.
