Image: Protecting the Meteosat Third Generation–Imaging satellite from the sun
From ESA's Materials and Electrical Components Laboratory—one of a suite of labs based at the ESTEC technical center in Noordwijk, the Netherlands—a view from an intricate test campaign for the next generation of European weather satellites.
The near infrared detector assembly of the Flexible Combined Instrument (FCI) imager aboard the Meteosat Third Generation—Imaging (MTG—I) satellite was found to be susceptible to unwanted "stray light" from the sun.
A solution was proposed to reduce this vulnerability: a very thin metal mask would be glued atop the assembly, with carefully designed slits that would allow light to penetrate only in the desired areas, minimizing the entry of stray light.
But the feasibility of this solution needed to be tested, in order to demonstrate if the alloy cover would remain securely in place as incoming direct sunlight heats it up repeatedly during moments of sun intrusion.
Accordingly, a new feature was added to the Electrostatic Discharge (ESD) facility, part of the Materials and Electrical Components Lab. Originally designed as a vacuum chamber to expose samples to mono-energetic electrons down to cryogenic temperature, the ESD was upgraded to host an optical rack to hold a light source to simulate sunlight exposure onto the sample.
Video: European Robotic Arm ready for space
The European Robotic Arm (ERA) will be launched to the International Space Station together with the Russian Multipurpose Laboratory Module, called 'Nauka'. ERA is the first robot able to 'walk' around the Russian segment of the Space Station. It has the ability to anchor itself to the Station and move back and forward by itself, hand-over-hand between fixed base-points. This 11-metre intelligent space robot will serve as main manipulator on the Russian part of the Space Station, assisting the astronauts during spacewalks. The robot arm can help install, deploy and replace elements in outer space
ERA is 100% made-in-Europe. A consortium of European companies led by Airbus Defence and Space Netherlands designed and assembled it for ESA. The robotic arm is largely funded by the Dutch government.
Russia to launch new International Space Station module
The long-delayed Russian module for the International Space Station is set to be finally launched this month, but the date has been pushed back several days, the head of the country's space corporation said Thursday.
Roscosmos director Dmitry Rogozin said on Twitter that the Nauka (Science) module is now scheduled to be launched from the Russian launch facility in Baikonur, Kazakhstan on July 21. The following two days could serve as reserve dates for the launch.
Russian space officials had earlier said that the launch previously set for July 15 was postponed because of the need to fix some unspecified flaws.
The launch of Nauka, also called Multipurpose Laboratory Module, has been repeatedly delayed because of technical problems.
It was initially scheduled to go up in 2007. In 2013, experts found contamination in its fuel system, resulting in a long and costly replacement. Other Nauka systems also underwent modernization or repairs.
The 20-metric-ton module is set to be put to orbit by a Proton-M booster rocket. It's intended to provide Russian astronauts onboard the space outpost with their own room and capacity for lab research.
NASA Selects Moog to Power and Control VIPER Lunar Rover
Moog Inc. report sthat the company's space products have been selected for an upcoming NASA mission to explore the Moon's South Pole. The Volatiles Investigating Polar Exploration Rover, or VIPER, is NASA's first mobile robotic rover mission to the Moon. VIPER will rely on Moog's radiation-hardened avionics technology to control the rover during its 100-day mission. The Integrated Avionics
How does satellite communication work? ROBert explains all!
Trying to explain satellite communication to children is no easy task, so why not let robot host ROBert help? In the third of the ROBert Knows videos created by ESA and PLAYMOBIL, ROBert examines how satellite communication works with a little help from our own expert Director of TIA, Elodie Viau.

Sea to stars: first Arab woman astronaut in training
The UAE's Nora al-Matrooshi is the first Arab woman to start training to be an astronaut, one of two Emiratis picked from thousands of applicants as the Gulf nation looks to the stars.
The 28-year-old mechanical engineer from Sharjah—one of the seven emirates that make up the UAE—has dreamt about space since she was a girl, learning about planets and stars at school.
And while there are no space missions scheduled, she hopes to have the opportunity to one day visit space, continuing the tradition of exploration begun by her sailor ancestors.
Image: The heart of a lunar sensor
The heart of the Exospheric Mass Spectrometer (EMS) is visible in this image of the key sensor that will study the abundance of lunar water and water ice for upcoming missions to the Moon.
This spectrometer is being delivered to NASA today as part of the PITMS instrument for its launch to the Moon later this year.
EMS is based on an 'ion trap', an ingenious detector device that allows researchers to identify and quantify sample atoms and molecules in a gas and allows to establish a corresponding mass spectrum. Scientists at The Open University and RAL Space are developing EMS under an ESA contract.
Lunar molecules entering the sensor are bombarded by electrons emitted by a heated wire to create ions. The resulting ions are stored within an electric field formed by a set of precisely-shaped electrodes. The ions are then released from this 'trap' in order of increasing mass/charge ratio into the detector that identifies and quantifies their chemical makeup.
This will allow the instrument to measure water and other molecules in the very thin atmosphere of the Moon throughout the lunar day to study a lunar 'water cycle' concept.
Small amount of lithium production in classical nova
A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical novae and implies that nova explosions alone cannot explain the amount of lithium seen in the current universe.
