ESA's Educational CubeSat Program

"ESA invites European student teams who are building CubeSats with mainly educational objectives to propose their satellite for the new 'Fly Your Satellite!' programme. 'Fly Your Satellite!' is an exciting new initiative from the ESA Education and Knowledge Management Office. It is focused on CubeSat projects run by university students and builds on the successful 'CubeSats for the Vega Maiden Flight' pilot programme, which culminated in 2012 with the launch of seven university student-built CubeSats on board the Vega Maiden Flight. In the future, this new initiative is intended to cover the complete development process of a satellite from concept to launch. However, the 2013 edition will be dedicated to teams whose satellite is already at an advanced stage of development and able to complete the Flight Model assembly by June 2013. One, two or three-unit CubeSats are eligible." More

Finding the key to immunity in Space

Living in space weakens astronauts' immune systems, researchers have discovered. The findings are providing clues on how to tackle diseases on Earth before symptoms appear.

Mapping Mars

Nearly 90% of Mars' surface has been mapped by the high-resolution stereo camera on ESA's Mars Express, which celebrates ten years since launch this June.

Building a Lunar Base with 3D Printing

"Setting up a lunar base could be made much simpler by using a 3D printer to build it from local materials. Industrial partners including renowned architects Foster + Partners have joined with ESA to test the feasibility of 3D printing using lunar soil. "Terrestrial 3D printing technology has produced entire structures," said Laurent Pambaguian, heading the project for ESA. "Our industrial team investigated if it could similarly be employed to build a lunar habitat." Foster + Partners devised a weight-bearing 'catenary' dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a pressurised inflatable to shelter astronauts. A hollow closed-cell structure - reminiscent of bird bones - provides a good combination of strength and weight." More

"A new satellite mission designed by university students is entering the advanced stages of development. A new contract appoints ALMASpace, Italy, the prime contractor. The European Student Earth Orbiter (ESEO) is a micro-satellite mission to low Earth orbit. Newly appointed prime contractor ALMASpace, Italy, will now oversee its final development, integration, testing, and in-orbit commissioning by European university students. The mission's primary goal is to provide students with extensive, hands-on experience of a space project. This will equip them with the necessary skills to confidently enter the high-technology workplace of Europe's future. 'With ESEO, ESA's Education and Knowledge Management Office will continue pursuing its objective of offering hands-on activities to university students across Europe. Working on real space projects has a strong inspirational value and offers the best professional preparation for Europe's future engineers and scientists,' says Piero Galeone, ESA's Head of the Tertiary Education Unit."

Stars Can Be Late Parents

Using the unique capabilities of ESA's Herschel space observatory, astronomers have accurately 'weighed' a star's disc, finding it still has enough mass to spawn 50 Jupiter-sized planets, several million years after most other stars have already given birth.

Andromeda's Colorful Rings

The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation.

When a Planet Behaves Like a Comet

ESA's Venus Express has made unique observations of Venus during a period of reduced solar wind pressure, discovering that the planet's ionosphere balloons out like a comet's tail on its nightside.

Betelgeuse Braces for a Collision

Multiple arcs are revealed around Betelgeuse, the nearest red supergiant star to Earth, in this new image from ESA's Herschel space observatory. The star and its arc-shaped shields could collide with an intriguing dusty 'wall' in 5000 years.

Earth From Space: The Bay Area

This image, acquired by Landsat-7 on 2 January, shows the San Francisco Bay Area in the US state of California.

ESA's Mars Express imaged the striking upper part of the Reull Vallis region of Mars with its high-resolution stereo camera last year.

ESA agreed with NASA today to contribute a driving force to the Orion spacecraft planned for launch in 2017. Ultimately, Orion will carry astronauts further into space than ever before using a module based on Europe's Automated Transfer Vehicle technology.

"Operating droids in space was no obstacle for a German-Italian alliance to reach the finish line of the Zero Robotics tournament. The European winners commanded mini-robots to dodge virtual dust clouds and rendezvous with disabled satellites, all in the weightlessness of the International Space Station. This year's competition gave over 130 high-school students from across Europe the opportunity to operate droids in space by coding software. Six alliances made of teams from Italy, Germany, Spain and Portugal witnessed how their computer codes worked in the Space Station from ESA's ESTEC space research and technology centre in the Netherlands The RetroSpheres space game involved two mini-robots racing through a course using the least amount of fuel. During the three-minute programmed dance, the volleyball-sized spheres moved using 12 squirts of compressed gas. Competitors could collect extra fuel from decommissioned satellites and deorbit the satellites for extra points while navigating through their opponent's dust clouds." More

Testing time for Proba-V

"ESA's Proba-V microsatellite is now assembled and midway through testing to ensure it is fully spaceworthy. The miniature Earth-observer, designed to chart global vegetation every two days, will be launched in April. The testing at the specialised Intespace facility in Toulouse, France, includes rigorous simulations of Proba-V's take-off conditions and the hard vacuum and temperature extremes it must endure in orbit. It comes after Proba-V's assembly was completed by prime contractor QinetiQ Space at its facility in Kruibeke, Belgium last month. Building it was a complex operation. Although smaller than a cubic metre, the satellites carries a wide-angle telescope for its main Earth-monitoring instrument, a pair of radiation sensors, a fibre optic connector experiment, a prototype radio transmitter based on the semiconductor gallium nitride, and a test receiver to track aircraft in flight all around the globe."

Herschel Intercepts Asteroid Apophis

ESA's Herschel space observatory made new observations of asteroid Apophis as it approached Earth this weekend. The data shows the asteroid to be bigger than first estimated, and less reflective.

An Asteroid Belt Around Vega?

Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the second brightest star in northern night skies. The scientists used data from NASA's Spitzer Space Telescope and the European Space Agency's (ESA) Herschel Space Observatory, in which NASA plays an important role.

Mars Express Image: Charitum Montes

The high-resolution stereo camera on ESA's Mars Express imaged the Charitum Montes region of the Red Planet on 18 June, near to Gale crater and the Argyre basin featured in our October and November image releases.

A Census of the Invisible Universe

By combining the observing powers of ESA's Herschel space observatory and the ground-based Keck telescopes, astronomers have characterized hundreds of previously unseen starburst galaxies, revealing extraordinary high star-formation rates across the history of the universe.

Six years of observations by ESA's Venus Express have shown large changes in the sulphur dioxide content of the planet's atmosphere, and one intriguing possible explanation is volcanic eruptions.
