Καλώς ήλθατε στο νέο επεισόδιο του Space. Προσπαθήστε να φανταστείτε ένα ηλιακό μοντέλο στο οποίο κάποιοι πλανήτες θα έχουν κάτω από την επιφάνεια περισσότερο νερό από ότι υπάρχει στη γη.
Αυτός είναι ο επόμενος στόχος της Ευρωπαϊκής Υπηρεσίας Διαστήματος. Θα επανέλθουμε στο θέμα, αφού πρώτα μάθουμε κάποια διαστημικά νέα.
The journey and final orbit of LISA Pathfinder, ESA’s technology demonstration mission that will pave the way for future gravitational-wave observatories in space.
LISA Pathfinder is scheduled for launch on 2 December 2015 on a Vega rocket from Europe’s Spaceport in French Guiana. Vega will place the spacecraft into an elliptical orbit, with a perigee (closest approach to Earth) of 200 km, apogee (furthest point) of 1540 km, with the path angled at 6.5º to the equator.
Then, once Vega’s final stage is jettisoned, LISA Pathfinder will continue under its own power, beginning a series of six apogee-raising manoeuvres over the next two weeks.
The last burn will set LISA Pathfinder on its way towards its final orbiting location. The cruise will last about six weeks, and the propulsion module will be discarded along the way four weeks in.
Eventually, the spacecraft will circle the L1 Sun–Earth Lagrangian point. There, LISA Pathfinder will begin its six months of demonstrating key technologies for space-based observation of gravitational waves.
The iconic group Inspiral Carpets from Oldham, Greater Manchester, have dedicated their classic song Saturn V to ESA astronaut Tim Peake. Formed by musicians Graham Lambert and Stephen Holt in 1983, Inspiral Carpets were one of the bands associated with the ‘Madchester’ scene that came to prominence in the late 1980s and early 1990s. The band send this message: “From Inspiral Carpets, with respect and love, to our friend Tim Peake!”
Tim Peake is set for launch to the International Space Station on his five-month Principia mission on 15 December 2015.

A major scientific discovery was announced by NASA at a Sept. 28 news conference. From its vantage point high above the Martian surface, NASA’s Mars Reconnaissance Orbiter (MRO) spacecraft has found the strongest evidence yet, that under certain circumstances, liquid water has been found on Mars. Researchers say an imaging spectrometer on MRO detected signatures of hydrated minerals on slopes where downhill streaks, known as Recurring Slope Lineae (RSL) are seen. In the past, RSL flows have been described as possibly related to liquid water. But the new findings of hydrated minerals is key evidence. Hydrated salts can lower the freezing point of liquid brine – and produce liquid water.

ESA astronaut Andreas Mogensen, the first astronaut from Denmark, explains the deployment of the student-built AAUSAT5 CubeSat – the first ESA student CubeSat mission launched from space and the pilot project of ESA’s ‘Fly Your Satellite from the ISS!’ education programme.
AAUSAT5, a CubeSat entirely built by a university team with ESA’s support, was launched to the International Space Station aboard the Japanese HTV-5 cargo vehicle 19 August 2015. Andreas gives a brief tour of the Japanese cargo vehicle’s storage space, where AAUSAT5 was housed during its flight to the Station. AAUSAT5 was taken to the Japanese Kibo Laboratory, put in a Nanoracks deployer, and placed into the airlock to be launched into space.
AAUSAT5 will be deployed into orbit 5 October 2015. Aalborg University will host a special event in Aalborg, Denmark entitled “ESA CubeSats from the Space Station: a new path for education and technology” to celebrate the deployment.
On 30 September 2015, Ariane 5 flight VA226 lifted off from Europe’s Spaceport in French Guiana and delivered two telecom satellites, Sky Muster and Arsat-2, into their planned orbits.
During a news conference at NASA headquarters, agency scientists and officials discussed new findings from the Mars Reconnaissance Orbiter (MRO) that provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These downhill flows, known as recurring slope lineae (RSL), often have been described as possibly related to liquid water.
“11,2 km/s” is the official theme music for ESA’s Estrack ground station network. It was composed by Gautier Acher, a 17-year-old student living in Paris, France, and entered in the 2015 Tracking Station Music Contest, which celebrated the 40th anniversary of the Estrack network.
Gautier’s top-ranked entry was selected from a field 117 submissions received from over a dozen countries.
Gautier wrote: This track is a triptych that shows space is vast, but is full of interesting things, such as humankind, stars, comets, planets… It describes great achievements, in the past, and in the future.
While only three entrants could win prizes in the music contest, and only 10 could be at the top, the ESA judging panel praised all 117 submissions.
Judges commented that, “We heard some marvellous stuff created by people who are passionate, motivated and imaginative in their pursuit of music that reflects the central themes of exploration into our Universe, technological excellence and the dreams of humanity’s journeys into space.”
In 1975, the ground station at Villafranca in Spain became the kernel of the ESA tracking network, which now comprises 10 stations in seven countries and in 2015 celebrates four decades of providing links to space for ESA’s science, Earth, observatory and exploration missions.
Since inception, Estrack has expanded worldwide and today employs cutting-edge technology to link mission controllers with spacecraft orbiting Earth, voyaging deep in our Solar System and anywhere in between (more information in our Estrack web site http://www.esa.int/estrack).
ESA Education mascot Paxi was placed in a Large Diameter Centrifuge gondola which normally houses researchers’ and students’ experiments at ESA’s ESTEC establishment. As the centrifuge starts spinning, the relative g-levels within the gondola increase and this causes Paxi’s weight to increase. At 20 g, Paxi weighs 20 times what he normally does on Earth. As the centrifuge spins down, the g levels decrease and eventually when the centrifuge stops, return to normal.
Sept. 15 marked the halfway point in the yearlong mission on the International Space Station with NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko.

Aboard the International Space Station, Expedition 45 Commander Scott Kelly and Flight Engineer Kjell Lindgren of NASA took time out of their work schedule to talk to Sebastian Stan and Mackenzie Davis, cast members of the new movie “The Martian”, during a visit they made to Mission Control at the Johnson Space Center, Houston Sept. 15. They were joined by JSC Director Ellen Ochoa. Kelly is at the midway point of a year-long mission aboard the orbital laboratory with Russian cosmonaut Mikhail Kornienko of the Russian Federal Space Agency (Roscosmos), gathering valuable biomedical data that will be used in the formulation of a future human mission to Mars. Lindgren, who is a medical doctor, is beginning the third month of a five-month mission on the outpost.
Ridley Scott, director of the 20th Century Fox film “The Martian”, based on author Andy Weir’s book of the same name, reflects on the long-term personal and wide-ranging human fascination with Mars and how NASA’s exploration of the Red Planet is helping to turn science fiction into science fact.
ESA’s Earth-orbiting Proba-2 satellite observed three partial solar eclipses on the morning of 13 September 2015 along with an additional passage of the Moon close to the edge of the Sun. The image was taken with Proba-2’s SWAP imager, which views the solar disc at extreme ultraviolet wavelengths to capture the turbulent surface of the Sun and its swirling corona, which can clearly be seen in between eclipses in this movie. The Sun’s rotation can also be seen.
Aboard the International Space Station, the Expedition 45 crew – including new Commander Scott Kelly and Kjell Lindgren of NASA, said goodbye to Gennady Padalka of the Russian Federal Space Agency, Andreas Mogensen of ESA (European Space Agency) and Aidyn Aimbetov of the Kazakh Space Agency (Kazcosmos) as the trio climbed aboard their Soyuz spacecraft for the return trip to Earth. The Soyuz landed safely in Kazakhstan on Sept. 11 Eastern time, Sept. 12 in Kazakhstan — closing out a 168-day mission for Padalka and an 8-day stay on the station for Mogensen and Aimbetov.

Putting a round peg in a round hole is not hard to do by someone standing next to it. But on 7 September 2015 ESA astronaut Andreas Mogensen did this while orbiting 400 km up aboard the International Space Station, remotely operating a rover and its robotic arm on the ground.
Andreas used a force-feedback control system developed at ESA, letting him feel for himself whenever the rover’s flexible arm met resistance.
These tactile sensations were essential for the success of the experiment, which involved placing a metal peg into a round hole in a ‘task board’ that offered less than a sixth of a millimetre of clearance. The peg needed to be inserted 4 cm to make an electrical connection.
Andreas managed two complete drive, approach, park and peg-in-hole insertions, demonstrating precision force-feedback from orbit for the very first time in the history of spaceflight.
The Interact Centaur rover used in the experiment was based at ESA’s technical centre ESTEC in Noordwijk, the Netherlands. It was designed and built by ESA’s Telerobotics & Haptics Laboratory in collaboration with graduate students from Delft University of Technology.
The Interact experiment is a first step towards developing robots that provide their operators with much wider sensory input than currently available. In this way, ESA is literally ‘extending human reach’ down to Earth from space.
A composite day at ESTEC, the European space research and technology centre, as depicted in time-lapse format.
Located in Noordwijk, the Netherlands, ESTEC is Europe’s largest place for space, the technical heart of the European Space Agency. For almost all European space missions, the path to space leads through ESTEC.
Around 2700 people arrive here for work every day, working on a broad range of space activities from scientific exploration to telecommunications, Earth observation to navigation, robotics to human spaceflight.
A suite of unique laboratories probe every aspect of the space environment, applying decades of hard-won expertise. Seen here is preparation for testing materials in simulated space conditions as well as atomic force microscopy, employing a nanometer-wide tip like a stylus across a record player to reveal surface topography down to the atomic scale.
Full-scale testing of satellites takes place in the ESTEC Test Centre, including the Maxwell Chamber, kept isolated from the external world for precision electromagnetic testing, and the Large Space Simulator, Europe’s largest vacuum chamber used to reproduce the airlessness and temperature extremes encountered in space. The chamber uses large quantities of liquid nitrogen to mimic the chill of deep space.
Erasmus is ESTEC’s human spaceflight facility, supporting researchers in the design and performance of experiments in microgravity conditions. Also based there is ESTEC’s Telerobotics lab – developing methods of remotely controlling robots using force feedback, extending the human sense of touch to space. The lab team are putting the finishing touches to the Interact Centaur rover, a robot designed to be operated remotely by astronauts in orbit.
The European Space Agency’s ARTES programme for Advanced Research in Telecommunications Systems, helps to create products, services and infrastructures that benefit millions of people worldwide and make a major contribution to the European economy.
The economic engine of the space industry is satellite communications, generating over $140 billion a year in global revenues. The ARTES programme exists to support innovation, helping to transform research and development into commercial products and services.
ESA’s telecom programmes often take the form of public–private partnerships. ESA joins forces with industry to share the cost and risk, resulting in faster and more innovative technological advances than if either undertook the project alone.
The most recent high-profile telecom programmes are Alphasat, the largest European telecom satellite ever built and the European Data Relay System, a groundbreaking space and ground infrastructure that uses laser links to send data at unprecedented speeds.
ARTES also promotes the use of satellites in new and imaginative ways. Satellite communications can be applied in areas as diverse as healthcare, education, transport and security to deliver services and improve daily life.
This is the Interact Centaur rover that ESA astronaut Andreas Mogensen will be operating from orbit aboard the International Space Station, to drive into position and then perform an operation requiring sub-millimetre precision.
Developed by ESA’s Telerobotics and Haptics Laboratory, the Interact Centaur is a 4×4 wheeled rover combining a camera head on a neck system, a pair of highly advanced force sensitive robotic arms designed for remote force-feedback-based operation and a number of proximity and localisation sensors.
As demonstrated here, Andreas will first attempt to guide the robot to locate an ‘operations task board’ and then to remove and plug a metal pin into it, which has a very tight mechanical fit and tolerance of only about 150 micrometres, less than a sixth of a millimetre.
As currently scheduled, Monday 7 September should see the Interact rover driven around the grounds of ESA’s ESTEC technical centre in Noordwijk, the Netherlands, from the extremely remote location of Earth orbit, 400 km up.
Signals between the crew and the robot must travel a total distance of approximately ninety thousand kilometres, via a satellite constellation located in geostationary orbit. Despite this distance, Andreas will exactly feel what the robot does on the surface – with only a very slight lag.
ESA astronaut Andreas Mogensen, commander Sergei Volkov and Aidyn Aimbetov were launched into space this morning 2 September at 04:37:43 GMT (06:37:43 CEST) from Baikonur cosmodrome, Kazakhstan.
The launch marks the start of ESA’s 10-day ‘iriss’ mission that will focus on testing new technologies and ways of running complex space missions.
The astronaut’s Soyuz TMA-18M spacecraft was pushed into Earth orbit as planned accelerating 50 km/h on every second for the first nine minutes of their launch.
The spacecraft separated from the Soyuz launcher at 04:46 GMT (06:46 CEST)
Artist’s impression of the launch of LISA Pathfinder, ESA’s technology demonstration mission that will pave the way for future gravitational-wave observatories in space.
Scheduled to lift off on a Vega rocket from Europe’s Spaceport in French Guiana in late 2015, LISA Pathfinder will operate at the Lagrange point L1, 1.5 million km from Earth towards the Sun. After launch, the spacecraft will take about eight weeks to reach its operational orbit around L1.
The Vega rocket is designed to take small payloads into low-Earth orbit. The animation shows the rocket shortly after launch, rising above our planet and releasing the fairing.
Vega will place the spacecraft onto an elliptical orbit with perigee at 200 km, apogee at 1540 km and angled at about 6.5° to the equator. Then, LISA Pathfinder will continue on its own, using its separable propulsion module to perform a series of six manoeuvres and gradually raise the apogee of the initial orbit.
Eventually, LISA Pathfinder will cruise towards its final orbiting location, discarding the propulsion system along the way, one month after the last burn. Once in orbit around L1, the spacecraft will begin its six months of operations devised to demonstrate key technologies for space-based observation of gravitational waves.
It was a busy week for the crew aboard the International Space Station. The Japanese Aerospace Exploration Agency’s fifth H-II Transfer Vehicle, or HTV-5 arrived on Aug. 24 with more than 8,000 pounds of equipment, supplies and experiments in its pressurized cargo compartment. The delivery included an investigation that will search for signatures of dark matter, as well as enough additional food and supplies to last through 2015. Also, Soyuz relocated to Zvezda, Orion parachute drop test, Rising Seas, Hurricane Katrina remembrance, Tail first crash test, Webb telescope’s backplane arrives and Hubble’s double black hole!
The Rosetta Mission has been writing a new chapter in what we know about the formation of life. The ESA teams involved are now preparing for the last part of this amazing journey.
Comet Churyumov-Gerasimenko has recently reached the perihelion – that’s the closest point to the Sun in its six and a half year orbit. It’s an important scientific step – as increasing solar energy warms the comet’s frozen ices, turning them to gas and dust. To stay safe, Rosetta has been forced to move further from the comet.
The Rosetta mission has been extended by nine months – until September next year. It’s hoped this will further boost the enormous amount of data that’s already been collected.
Using a Cessna 172 dropped from a height of 100 feet, NASA’s Search and Rescue Mission Office simulated a severe but survivable plane accident Wednesday, Aug. 26 at the agency’s Langley Research Center to test emergency locator transmitters (ELTs). The devices are installed on general aviation and commercial planes to transmit a location signal in the event of a crash. On this third and final test in the series the plane was dropped from 100 feet, tail down into the ground.
On 20 August 2015, Ariane 5 flight VA225 lifted off from Europe’s Spaceport in French Guiana and delivered two telecom satellites, Eutelsat-8 West B and Intelsat-34, into their planned orbits.
The fourth of ESA’s ‘Class of 2009’ astronauts to fly, Andreas Mogensen from Denmark will soon undertake a ten day mission to the International Space Station. With a background in aerospace engineering, he has spent the last six years training with the Station’s international partners for his inaugural spaceflight, taking part in a wide variety of activities to prepare him for the mission.
