AAUSAT4

AAUSAT4

The miniature Aausat satellite undergoes repeated temperature variations in a vacuum chamber, cooling the CubeSat to –10°C and heating it to +45°C for more than two weeks. This harsh baptism will make sure that it can cope with the conditions in space.

Aausat is a 10x10x10 cm satellite designed and built by students of the Aalborg University in Denmark. As part of ESA education’s Fly Your Satellite! programme, the satellite will be sent into space and the students are have the chance to test it at ESA’s technical heart, ESTEC, in the Netherlands.

The wires trailing from the satellite are to measure temperature and for power – it will fly without the wires and plastic casing.

The satellite seen here, Aausat4, will track ships around Greenland using radio identification signals. Its predecessor, Aausat3, is reaching the end of its life after 18 months in space, having received 100 000 signals from ships in the first week alone.

Aausat4 features a significant upgrade in software and better-protected solar panels that will deliver more power. ESA’s education programme is supporting Aausat4 testing, and if the satellite confirms its flightworthiness, the Agency will sponsor a launch opportunity.

“Aausat4 is run and made by students,” explain Mathias Mølgaard and Kasper Hemme, students from Aalborg University. “The systems are designed inhouse and it has been a great help for completing our thesis.”

“ESA Education is offering interesting hands-on programmes to university students,” says Piero Galeone, programme manager for Fly Your Satellite! “Students can participate in space programmes under ESA supervision, and can use state-of-the-art facilities, acquainting themselves with concepts and work practice used by space professionals.”

Aausat5 will be a copy of this model, but it will be released into space in 2015 by none other than Danish ESA astronaut Andreas Mogensen during his nine-day mission on the International Space Station.

Centaurus A halo

This image shows the stunning elliptical galaxy Centaurus A. Recently, astronomers have used the NASA/ESA Hubble Space Telescope to probe the outskirts of this galaxy to learn more about its dim halo of stars.

The galaxy’s halo of stars has been found to reach much further than expected, extending across 4 degrees in the sky – equivalent to eight times the apparent width of the Moon, or almost twice the width of this image.

This image is a composite of images from Digitized Sky Survey 2 (DSS2), the MPG/ESO 2.2-metre telescope, and the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys (ACS).

The areas probed by Hubble are identified in the annotated version of this image. Hubble’s unique capabilities allowed astronomers to analyse the faint stars in the halo.

ESA’s Intermediate eXperimental Vehicle, IXV, is tilted and turned along and around all three axes at ESA’s Technical Centre, ESTEC, in the Netherlands to measure its centre of gravity and moments of inertia, because both influence its flying characteristics.

Launched on Vega in early November 2014, IXV will flight-test the technologies and critical systems for Europe’s future automated reentry vehicles returning from low orbit.

…Es war einmal eine Raumsonde namens Rosetta. Rosetta fliegt bereits seit 10 Jahren in Richtung eines Kometen namens 67P/Churyumov-Gerasimenko. Es sollte nicht lange dauern bis Rosetta den Kometen in der Ferne sehen konnte. Sie kam ihm immer näher. Es war der schönste Anblick, den sie je gesehen hatte.

EPA Warning: Recharging Air Conditioners with Wrong Refrigerant Poses Injury and Fire Risks

WASHINGTON – The U.S. Environmental Protection Agency (EPA) is cautioning homeowners, manufacturers of propane-based refrigerants, home improvement contractors and air conditioning technicians of the safety hazards related to the use of propane in existing motor vehicle and home air conditioning systems.

A number of refrigerants with “22a” or “R-22a” in the name contain highly flammable hydrocarbons, such as propane. These refrigerants are being marketed to consumers seeking to recharge existing home and motor vehicle air conditioning systems that were not designed to use propane or other flammable refrigerants. These refrigerants have never been submitted to EPA for review of their health and environmental impacts and are not approved for use in existing air conditioning systems.

Using propane-based refrigerant in an air conditioner that is not designed for flammable refrigerants poses a threat to homeowners as well as service technicians because systems that are recharged with “22a” refrigerants can catch fire or explode resulting in injury and property damage. EPA is investigating instances where propane-based refrigerants have been marketed and used as a substitutes for HCFC-22 (R-22) and will take enforcement actions where appropriate.
