Simulating space for JWST’s four infrared instruments

Simulating space for JWST’s four infrared instruments

Building a space telescope is no mean feat. Conditions here on Earth are drastically different from those experienced in orbit around our planet. How do we know that any telescope built in our controlled laboratories can withstand the harsh environment of space?

Luckily, we can recreate space-like conditions using simulators such as this thermal–vacuum chamber at NASA’s Goddard Space Flight Center in Maryland, USA. In this image, the chamber is not in action, as shown by the presence of a photographer wielding a torch on the sidelines. When switched on, multiple pumps suck all the air out to create a space-like vacuum, and the temperature can drop to a toe-curlingly low –253°C.

However, the real star of this image is the futuristic gold-coloured frame and its contents. This frame holds the Integrated Science Instrument Module, a structure containing the science instruments for 2018’s James Webb Space Telescope, or JWST, successor to the Hubble Space Telescope.

Along with the frame, this module weighs about as much as an elephant and houses four instruments to observe in the infrared, a part of the spectrum that is key for exploring the origins of the Universe and the properties of very distant cosmic objects.

This capability is the reason for the chamber’s extremely low temperature: infrared light is emitted by warm objects. To avoid infrared emissions from the telescope itself interfering with JWST’s observations, the entire telescope must be cooled to very low temperatures.

In space, JWST will make use of a giant sunshield to keep it completely in the shadows. This will keep the telescope at –233°C.

The JWST team hit a milestone last summer as all four science instruments passed their cryogenic testing in this chamber. The three near-infrared units were cooled to around –233°C, while the mid-infrared instrument reached an even lower –266°C, for a total of 116 days. For more information, read here.

After these tests, one of the units – the Near InfraRed Spectrograph – was removed and fitted with new detectors and ‘microshutters’, a new technology to study hundreds of celestial objects simultaneously using minuscule windows the width of a human hair. When this upgraded instrument is returned, the entire module will continue with further environmental tests to reproduce the conditions endured during launch and in space. For more information, read here.

JWST is a joint project of NASA, ESA and the Canadian Space Agency.

EPA Approves New Climate-Friendly Refrigerants

Rule supports president’s Climate Action Plan by curbing emissions of potent greenhouse gases

WASHINGTON – As part of President Obama’s Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is increasing the options for refrigerants used in various kinds of refrigeration and air conditioning equipment in the United States that offer better climate protection without harming the ozone layer. This final action addresses refrigerants under the Climate Action Plan that calls on EPA’s Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals.

“Today’s rule is an example of how we can turn the challenge of climate change into an opportunity to innovate our way to a better future,” said EPA Administrator Gina McCarthy. “By working together, businesses and EPA are bringing new, climate-friendly refrigerants to market that better protect our health and the environment.”

Under the authority of the Clean Air Act, EPA’s SNAP Program evaluates substitute chemicals and technologies that are safe for the ozone layer. This final rule expands the list of SNAP-approved substitutes to include more low-global warming potential (GWP) alternatives that can replace both the ozone-depleting substances and high-GWP hydrofluorocarbons (HFCs). The approved substitutes have GWPs that range from 3 to 675 and can replace older compounds with GWPs between 1400 to 4000.

After receiving input from industry, environmental groups, and others, EPA is approving additional low-GWP hydrocarbon refrigerants, subject to use conditions, in the following refrigeration and air conditioning applications:

• Ethane in very low temperature refrigeration and in non-mechanical heat transfer;

• Isobutane in retail food refrigeration (stand-alone commercial refrigerators and freezers) and in vending machines;

• Propane in household refrigerators, freezers, or combination refrigerators and freezers, in vending machines, and in room air conditioning units;

• The hydrocarbon blend R-441A in retail food refrigeration (stand-alone commercial refrigerators and freezers), in vending machines and in room air conditioning units; and

• HFC-32 (difluoromethane) in room air conditioning units. HFC-32 has one-third the GWP of the conventional refrigerants currently being used in room air conditioning units.

These refrigerants are already in use in many of these applications in Europe and Asia.

In addition to adding these climate-friendly alternatives, EPA is also exempting all of these substances, except HFC-32, from the Clean Air Act venting prohibition, as current evidence suggests that their venting, release, or disposal does not pose a threat to the environment.

This month’s Space focuses on startups in Europe that are finding everyday Earthly applications for space innovations.

There’s a long tradition of transferring technology from one sector to another to improve life on our planet, and in the case of space that can lead to some unlikely links between science success stories such as the Philae lander, and the hunt for bedbugs in hotel rooms, or between the Smart-1 moon mission and the efficiency of geothermal energy. We visit two of the 11 ESA business incubation centres around Europe, one in Barcelona, the other near Oxford.

Per quanto strano possa apparire, c’è un legame tra le cimici dei letti e il lander Philae. E anche tra l’energia geotermica e la missione lunare Smart-1.

In questa puntata di Space, vedremo come la tecnologia sviluppata per le missioni nello spazio trova svariate applicazioni anche sulla Terra.

Per aiutare le start-up a sviluppare queste innovazioni e a tradurle in prodotti da immettere sul mercato, l’Agenzia spaziale europea mette a disposizione gli spazi e la competenza dei suoi Business Incubation Centre. Degli undici presenti in Europa, ne abbiamo visitato uno a Barcellona e un altro a Harwell, nel Regno Unito.

Este mês, Space centra-se nas "startups" europeias que estão a encontrar aplicações diárias a partir da tecnologia projetada para ser usada em órbita.

Por estranho que possa parecer há uma ligação entre os percevejos, que podem existir numa cama de um quarto de hotel, e a sonda Philae, e entre a energia geotérmica e a missão lunar SMART-1.

Empreendedores, em Espanha e no Reino Unido, estão a trabalhar estas ligações. Para isso, estas e outras empresas, têm o apoio dos vários centros de incubação de empresas da Agência Espacial Europeia, que lhes dão apoio na construção do seu modelo de negócio, se este for viável.

Van kapcsolat a szállodai szobák poloskái és a Philae leszállóegysége, valamint a geotermikus energia és a Smart-1 holdszonda között. Olyan vállalkozókat mutatunk be, akik lehozzák a Földre az űrtechnológiát. Barcelona közelében egy startup cég a szó szoros értelmében szárnyalni kezd. Saját készítésű drónjuknál űrtechnológiát használnak a navigációhoz. Harwellben, Oxford közelében olyan startupokat láttunk, amelyeket a Philae, az űrhajósok és egy holdmisszió inspiráltak. Az ESA üzleti inkubációs egysége Taff Morgant segítette itt. Tudományos ismereteit, amelyeket a Philae leszállóegységénél végzett munkájakor szerzett, arra használja, hogy kifejlesszen egy rendszert a poloskák vadászására.

Brussels

This false-colour image from the Spot-5 satellite was acquired on 28 September 2011 over central Belgium, capturing the capital city of Brussels (left).

Zooming in on the city, we can see a number of large parks, such as the Parc du Cinquantenaire or Jubelpark in the city’s European Quarter – home to the institutions of the European Union. Brussels is the de facto capital of the EU, and is a major centre for international politics.

Further west, we can see the Parc de Bruxelles or Warandepark, where the Royal Palace of Brussels and Belgium Parliament are located.

Northeast of the city, we can see the runways of the Brussels Airport.

Darker blue areas throughout the image depict thick vegetation cover, such as the city parks and the large Sonian Forest south of Brussels. Stretching over 4400 hectares, the forest is home to animals such as deer, red squirrel and wild boar. Brown bear and wolf also once roamed this area, but have disappeared through human influence and changes in the ecosystem over hundreds of years.

In the upper right is the city of Leuven in the Flemish Region. The city is home to the headquarters of Anheuser-Busch InBev – the world’s largest brewing group that includes brands such as Beck’s, Budweiser and Stella Artois.
