27 February 2009
This is ISS status report No. 30 from the European Space Agency outlining ESA’s science related activities that have taken place on the ISS during the past week for different European experiments and experiment facilities, and additional information about European ISS systems and key ISS events for the time period. The report is compiled by ESA’s Human Spaceflight Coordination Office in cooperation with ESA’s Columbus and Payload Operations Management and Mission Science teams.
ISS Utilisation Programme
The principal focus of the European utilisation of the ISS is the Columbus laboratory, which was launched and permanently attached to the ISS in February 2008. In addition to the science taking place using the internal and external experiment facilities of the Columbus laboratory, ESA also has some further ongoing research taking place in the US Destiny laboratory and the Russian Segment of the ISS. The current status of the European science package on the ISS is as follows:
European science and research facilities inside the Columbus Laboratory
Biolab and WAICO experiment
Biolab was activated on 25 February and the bellow test on centrifuge B was performed though the error that occurred on 10 February was again experienced i.e. one of the experiment containers for the Waving and Coiling of Arabidopsis Roots (WAICO) experiment could not be properly engaged on the centrifuge. The engineering team on ground is working on a solution to this issue.
The next run of the Waving and Coiling of Arabidopsis Roots (WAICO) experiment in Biolab, will take place during Increment 19 following the arrival of the science part of the experiment. This science part with plant seeds will be transported in conditioned state tentatively on Shuttle flight 2J/A in May 2009.
Fluid Science Laboratory and Geoflow experiment
Geoflow scientific activities, which have already produced a significant amount of data, are currently on hold due to unexpected temperatures in the Geoflow Experiment Container during science run#10 on 9 January. The Geoflow Experiment Container is currently stowed for return to ground in order to carry out detailed failure analysis and repair. The resumption of the overall exhaustive Geoflow science programme will continue on resolution of this issue and upload of the experiment.
The Geoflow experiment investigates the flow of a viscous incompressible fluid between two concentric spheres rotating around a common axis under the influence of a simulated central force field. This is of importance for astrophysical and geophysical problems, such as global scale flow in the atmosphere, the oceans, and in the liquid nucleus of planets.
European Drawer Rack including the Protein Crystallisation Diagnostics Facility
With the launch of ISS flight 15A on STS-119 Shuttle Discovery being now rescheduled to 12 March, a new set of solution growth reactors, will be prepared by the Belgian User Support and Operation Centre in Brussels, for shipment to the Kennedy Space Center in time for the launch. These growth reactors filled with a variety of different protein solutions will replace the growth reactors currently in the Processing Unit of the Protein Crystallisation Diagnostics Facility, which is currently awaiting launch at Kennedy. The swap is necessary due to the aging risk of the protein samples. The Processing Unit will be flown in active mode (for continuous thermal conditioning of samples) to the ISS in the Shuttle middeck.
The Protein experiment series will last 3-4 months comprising 3 subsequent crystallisation cycles. The final set of organic protein macromolecules will be returned to Earth on the subsequent Shuttle flight 2J/A for detailed analysis in various European science labs. The European Drawer Rack is an experiment facility housing the Protein Crystallisation Diagnostics Facility, which is an advanced ISS research payload for the investigation of problems of protein crystallisation in space.
European Physiology Modules and NeuroSpat experiment
No operations were carried out with the European Physiology Modules facility this week. NeuroSpat will be the first experiment to use the European Physiology Modules facility. This will take place when the next European astronaut arrives on the Station. This will be Belgian ESA astronaut Frank De Winne at the end of May this year. De Winne will be a subject in the NeuroSpat experiment as will Canadian Space Agency astronaut and fellow Expedition crew member Bob Thirsk. The two astronauts will assist each other with experiment procedures. NeuroSpat will investigate the ways in which crew members’ three-dimensional perception is affected by long-duration stays in weightlessness. NeuroSpat will also serve an experiment from the European Commission within the SURE project.
The latest run of the Sodium Loading in Microgravity (SOLO) experiment finished on 20 February. Experiment samples from ISS Commander Mike Fincke are currently stowed in the European-developed MELFI freezer awaiting return to Earth on a future flight. SOLO is carrying out research into salt retention in space and related human physiology effects. The SOLO experiment also uses capabilities of the European Physiology Modules Facility.
The next experiment run of 3D Space is still planned during the ongoing Increment 18 by JAXA astronaut and ISS Flight Engineer Koichi Wakata as the second human test subject. This will occur after Shuttle flight STS-119/15A, which will bring Wakata to the Station, currently scheduled for launch on 12 March. This human physiology study investigates the effects of weightlessness on the mental representation of visual information during and after spaceflight. Accurate perception is a prerequisite for spatial orientation and reliable performance of tasks in space. The experiment has different elements including investigations of perception of depth and distance carried out using a virtual reality headset and standard psychophysics tests.
Flywheel Exercise Device
The Flywheel Exercise Device will be removed from its on-orbit storage location in the European Transport Carrier rack of the Columbus Laboratory for deployment and first functional checkout during the ongoing Increment 18 after Shuttle flight 15A in February 2009. This activation may also be anticipated in case the Shuttle launch should be significantly delayed. The Flywheel Exercise Device was launched to the ISS with Columbus in order to become an advanced exercise device for ISS astronauts and serving human physiology investigations in the area of advanced crew countermeasures.
Pulmonary Function System in Human Research Facility 2
The Pulmonary Function System is accommodated in NASA Human Research Facility number 2, which was relocated from the US Destiny laboratory to the Columbus laboratory on 1 October 2008. The Pulmonary Function System is an ESA/NASA collaboration in the field of respiratory physiology instrumentation, which analyses exhaled gas from astronauts' lungs to provide near-instant data on the state of crew health.
European Modular Cultivation System
No experiment activities were carried out in the European Modular Cultivation System (EMCS) this week. This space biology facility, which was flown to the ISS in July 2006, is dedicated to biological experiments such as the effects of gravity on cells, roots and physiology of plants and simple animals. It was developed by ESA and has been operated for two years under a bilateral barter agreement with NASA which is expected to be continued. Currently an option to perform a 2nd run of JAXA’s combined Cell Wall / Resist Wall experiment is being explored. This experiment is also of high interest for the European scientists involved in ESA’s Multigen experiment. Genara is the next ESA experiment to take place in the European Modular Cultivation System and will study plant (Arabidopsis) growth activity at a molecular level in weightlessness. This will help to better understand gravitropism and to find plant systems that compensate for the negative impact on plant growth in space. This experiment will take place at the end of Increment 20. After Genara, the execution of the next NASA experiment TROPI-2 is planned.
Microgravity Science Glovebox
The Microgravity Science Glovebox was activated this week in support of the US SPICE experiment. The Microgravity Science Glovebox was developed by ESA within a barter agreement with NASA. The Glovebox provides the ability to perform a wide range of experiments in the fields of material science, biotechnology, fluid science, combustion science and crystal growth research, in a fully sealed and controlled environment. The Microgravity Science Glovebox has been continuously used for NASA experiments and will again play an important role for ESA science during 2009 for the execution of the triple SODI (IVIDIL, DSC, Colloid) experiment series for advanced research in vibration effects on diffusion in liquids, diffusion measurements in petroleum reservoirs and the study on growth and properties of advanced photonic materials within colloidal solutions, respectively.
European science and research facilities outside the Columbus laboratory in open space
European Technology Exposure Facility (EuTEF)
The EuTEF platform has been operated continuously with one experiment powered down having completed the first part of its science objectives. EuTEF is a fully automated, multi-user payload facility mounted on the outside of the Columbus laboratory carrying a suite of experiments that require exposure to the open space environment. The experiments cover a variety of disciplines including material science, physics, astrobiology, astronomy, and space technology.
The status of each individual experiment is as follows:
- DEBIE-2: The ‘DEBris In orbit Evaluator’ is designed to be a standard in-situ space debris and micrometeoroid monitoring instrument. It has successfully performed data acquisition during the week though the science team has changed the thresholds limits on DEBIE-2 due to the occurrence of empty science packets after a certain amount of time caused by a sensor unit error. Troubleshooting of this issue is ongoing.
- DOSTEL: The DOSimetric radiation TELescope is a small radiation telescope. It continues to gather scientific data on the radiation environment outside the ISS.
- EuTEMP: This multi-input thermometer measured EuTEF temperatures during transfer to the outside of Columbus from the Shuttle cargo bay. It is currently inactive due to completion of the first part of its science objectives.
- EVC: The Earth Viewing Camera is a fixed-pointed Earth-observation camera. Images were successfully acquired this week on 24 February.
- EXPOSE-E: This series of exobiology experiments is continuing to acquire scientific data.
- FIPEX: This sensor is helping to build up a picture of the atmospheric environment in low-Earth orbit by measuring atomic oxygen. The period of science acquisition which had started on 18 February finished as planned on 23 February. The instrument started a new period of science acquisition on 25 February.
- MEDET: The Materials Exposure and Degradation ExperimenT (MEDET) is continuing to acquire continuous scientific data. Data from this experiment will help to evaluate the effects of open space on materials being considered for future use on spacecraft in low Earth orbit.
- PLEGPAY: The PLasma Electron Gun PAYload is the study of the interactions between spacecraft and the space environment in low earth orbit, with reference to electrostatic charging and discharging. PLEGPAY is currently shut down and ground teams are still analysing the outcome of the full memory dump in connection with deletion of Experiment 1.
- TRIBOLAB: Ball Bearing Experiment was activated at 30 rpm but went into non-nominal mode soon after. Troubleshooting activities continue on the experiment’s shaft driver motor. This series of experiments covers research in tribology, i.e. the research of friction in mechanisms and lubrication thereof under long-term open space conditions.
Having so far produced excellent scientific data, the SOLAR facility is again in Sun-pointing mode with the latest Sun observation window opening on 23 February. The SOLAR payload facility studies the Sun’s irradiation with unprecedented accuracy across most of its spectral range during a 2-year timeframe on-orbit.
MISSE-6A and -6B
The US materials exposure experiment is receiving power from Columbus and the experiments are continuing as planned. The Materials on the ISS Experiment (MISSE) is a US multi-investigator experiment provided by NASA but located on the outside of the Columbus laboratory. The two large MISSE-6 trays will be returned to Earth in the frame of the 17A Shuttle flight in August 2009. The experiment will evaluate the effect of the space environment on a large variety of exposed materials.
European science inside the Russian ISS Segment
In its experimental set up the Matroshka experiments consist of a simulated human body (head and torso) called the Phantom equipped with several active and passive radiation dosimeters. The Phantom will be tentatively relocated during Increment 18 to the Japanese Kibo laboratory and equipped with a set of new passive dosimeters. JAXA have already confirmed the technical accommodation feasibility assessments conclusion and now concrete implementation steps and bi-/tri-lateral agreements with JAXA and Russia can be envisaged for another experiment run until mid 2010. After that in the long-term Matroshka may be accommodated again on an external ISS platform to measure cosmic radiation levels in Low Earth Orbit which are of relevance for EVA activities.
GTS-2 (Global Transmission Service)
The instrument is functioning well after its reactivation on 15 January following a short period of inactivity whilst awaiting prolongation of its operational agreement. The Global Transmission Service (GTS) had been continuously on since early 2008. This experiment is intended to test the receiving conditions of a time and data signal for dedicated receivers on the ground. The time signal distributed by the GTS has special coding to allow the receiver to determine the local time anywhere on the Earth without user intervention. The main scientific objectives of the experiment are to verify under real space operation conditions: The performance and accuracy of a time signal transmitted to the Earth’s surface from low Earth orbit; the signal quality and data rates achieved on the ground; measurement of disturbing effects such as Doppler shifts, multi-path reflections, shadowing and elevation impacts.
Additional European science outside the ISS in open space
The Expose-R facility is currently stowed inside the Russian segment of the Space Station following the power interface problems that deferred its installation/activation outside the Russian segment of the ISS during the 23 December EVA. This failure was due to previously disconnected power cables inside the Zvezda Service Module. The next Russian EVA, which will install Expose-R on the Russian segment of the ISS is now under preparation for 10 March but will be performed at the latest during the next nominal Russian EVA in June. Meanwhile the Expose-R unit with the integrated experiments stays safely stored under controlled conditions inside the Russian ISS segment.
Expose-R is a suite of nine new astrobiology experiments (eight from ESA, one from IBMP, Moscow), some of which could help understand how life originated on Earth. This suite of experiments was transported to the International Space Station on Progress flight 31P, which docked with the ISS on 30 November. The experiments are accommodated in three special sample trays, which are loaded with a variety of biological samples including plant seeds and spores of bacteria, fungi and ferns, which will be exposed to the harsh space environment (Solar UV, cosmic radiation, vacuum), during the upcoming spacewalk, for about one and a half years.
The individual Expose-R experiments are as follows:
- AMINO: Photochemical processing of amino acids and other organic compounds in Earth orbit
- ENDO: Response of endolithic organisms to space conditions
- OSMO: Exposure of osmophilic microbes to the space environment
- SPORES: Spores in artificial meteorites
- PHOTO: Measurements of vacuum and solar radiation-induced DNA damages within spores
- SUBTIL: Mutational spectra of Bacillus subtilis spores and plasmid DNA exposed to high vacuum and solar UV radiation in the space environment.
- PUR: Responses of Phage T7, Phage DNA and polycrystalline uracil to the space environment.
- ORGANIC: Evolution of organic matter in space.
- IMBP: Exposure of resting stages of terrestrial organisms to space conditions.
Expose-R complements the exobiology science package that is performed in Expose-E, a twin facility which has been in operation on EuTEF since February 2008.
Video Lesson ESA 1
On 18 February, Mike Fincke and Sandra Magnus carried out the fourth session of Video Lesson ESA 1, recording items concerning eating, sleeping and working areas on the ISS onto a video cassette.
Columbus systems information
In addition to the Columbus experiment facilities mentioned above the Columbus systems have been working well. The US Human Research Facility 1 inside the Columbus laboratory was activated on 26 February in support of data download. Regular maintenance activities are ongoing during the ULF-2 stage, which is the time period following the undocking of Shuttle flight ULF-2 until the next Shuttle flight, which is currently scheduled for launch on 12 March 2009. Planning and preparation for the next stage of activities is currently ongoing. Some Columbus system equipment, which has undergone maintenance during the past weeks, is awaiting download on the next Shuttle flight.
ISS general system information and activities *
Automated Transfer Vehicle (ATV) hardware deinstallation
On 23 February Roscosmos cosmonaut and ISS Flight Engineer Yuri Lonchakov spent several hours deinstalling and stowing the Automated Transfer Vehicle proximity communications and control equipment in the Russian Zvezda Service Module following its testing on 18 February.
Kurs Automated Rendezvous and Docking System
On 24 February Yuri Lonchakov spent several hours dismantling Kurs equipment in the Zvezda Service Module. Kurs is the Russian system used for automated rendezvous and docking. The following day he installed a new Kurs unit in the Service Module and connected it to the BITS-12 onboard telemetry system. The new Kurs unit, that was delivered on the latest Progress flight, will be used for the majority of future Russian traffic to the ISS. On 26 February he re-installed the older Kurs unit back into the Zarya Module. This had been moved to Zvezda prior to docking of Progress 31P to replace the failed Kurs unit in the Service Module.
Regenerative Environment Control and Life Support Systems (ECLSS)
As in previous weeks, microbiology analysis was undertaken of samples taken from the new Water Recovery System, which forms part of the Regenerative ECLSS, needed in advance of an increase to a six-person ISS Crew in 2009. Samples were also prepared for post-flight analysis on ground.
Fluids and Combustion Facility
On 25 February NASA astronaut and ISS Commander Mike Fincke removed alignment guides on the Fluids and Combustion Facility to allow activation of the Passive Rack Isolation System before operations begin on the Fluids and Combustion Facility. He re-installed the alignment guides the following day. The Fluids and Combustion Facility is located in the Combustion Integrated Rack.
Elektron O2 generator
On 27 February Lonchakov checked out liquid unit circulation pumps on the Elektron O2 generator. The liquid units were first pressurised before checkout procedures started. At the end of the activity the liquid units were purged with pressurised nitrogen (N2) before powering down the test equipment.
Quest Airlock activities
Mike Fincke installed a wireless sensor unit accelerometer in the Quest airlock on 24 February for taking data during Shuttle STS-119/15A docking. The following day he undertook an audit of EVA equipment bags and a reconfiguration of the stowage situation in the Quest airlock on 25 February in preparation for the spacewalks during the next Shuttle mission. Two days later NASA astronaut and ISS Flight Engineer Sandra Magnus replaced a leaking quick disconnect of the Prebreathe Hose Assembly
Japanese High Definition Television system
On 24 February Sandra Magnus checked out of the High Definition Television system and Image Processing Unit in the Japanese Kibo Laboratory. As part of the activity she downlinked video data from a camcorder via the Image Processing Unit.
Intermodular Ventilation Valves
On 25 February Sandra Magnus performed maintenance on the Remote Manual Overrides of the Intermodular Ventilation valves in the European-developed Node 2 and the Destiny Laboratory. This involved adjusting the actuator handles to the correct operating configuration.
ISS Russian Segment laptops
On 27 February Yuri Lonchakov configured two spare US laptops for use in the Russian segment of the ISS. In one he installed a hard disk drive used with the Russian laptops, and the other he checked out with a hard disk drive and DVD carrying software.
Component Repair familiarisation
Sandra Magnus and Mike Fincke continued with Component Repair Equipment assessment activities during the week. The objective of this is to determine the feasibility of replacing items on orbit at the smallest basic level, i.e. not having to replace a whole unit, and thus reduce the amount of volume transported on space exploration missions for purely maintenance purposes. This included unsoldering components from an integrated circuit board and resoldering new components such as an integrated circuit chip.
Flight Readiness Review
Following a Flight Readiness Review on 25 February the launch of STS-119/Discovery has been moved to not earlier than 12 March. A second Russian EVA is in preparation for 10 March. This is a 5.5 hr EVA which will also install the EXPOSE-R, which failed to be installed a few months ago.
(*)These activities are highlights of the past week and do not include the standard periodic operational/maintenance activities on the ISS or additional research activities not mentioned previously. Information compiled with the assistance of NASA sources.
