Raumfahrt - Das Ende der Funkstille – Neue Methode zur Kommunikation von Raumfahrzeugen

.

Der Eintritt von Raumfahrzeugen in die Atmosphäre von Planeten gehört zu den heikelsten Phasen einer Raumfahrtmission. Die enorme Hitzeentwicklung beim Wiedereintritt beansprucht nicht nur das Material der Kapsel, sie verursacht auch einen elektrisch geladenen Plasmastrom. Dadurch werden Radiowellen abgeschirmt und die Besatzung kann während dieser kritischen Phase zum Teil minutenlang nicht mit der Bodenstation kommunizieren. In einem gemeinsamen Projekt forschen Wissenschaftler des Deutschen Zentrums für Luft- und Raumfahrt (DLR) mit ihren Kollegen der kalifornischen Stanford Universität an der Lösung dieses Problems.
Das Phänomen des "Blackouts" beim Übergang vom Vakuum des Weltalls in die dichtere Atmosphäre eines Planeten beschäftigt Generationen von Wissenschaftlern bereits seit den "Mercury", "Gemini" und "Apollo" Programmen der NASA in den 1960er und 1970er Jahren. In Höhen von 40 bis 90 Kilometern sind die durch Reibung entstehenden Plasmaströme für Radiowellen nicht zu durchdringen und unterbinden dadurch den Datenaustausch. Entscheidende Informationen, die zum Gelingen oder Scheitern einer Mission beitragen können, sind hierdurch nicht verfügbar. Zu Zeiten der Space-Shuttle-Ära wurde das Problem zum Teil durch die Form des Shuttle gelöst, da es bauartbedingt Bereiche gab, die eine geringere Dichte des Plasmastroms aufwiesen und so die Kommunikation zuließen. Entscheidend für die Dichte des ionisierten Stroms sind grundsätzlich Faktoren wie Eintrittswinkel, Geschwindigkeit (in der Regel Mach 20 bis 25) und Form des Raumfahrzeugs.
Tests im heißen Kanal
Am lichtbogenbeheizten Windkanal der Abteilung Über- und Hyperschalltechnologien, des DLR-Instituts für Aerodynamik und Strömungstechnik in Köln, fand im Januar 2016 eine Testkampagne statt, um Lösungen für diese Problematik zu finden. Zusammen mit US-amerikanischen Wissenschaftlern der Stanford Universität, unter Leitung von Siddarth Krishnamoorthy, wurden realistische Testbedingungen geschaffen. Die Versuchseinrichtung, bestehend aus einem Hitzeschild sowie einem dahinter liegenden Sender, wurde dazu einem mehrere tausend Grad heißen Plasmastrom ausgesetzt. Außerhalb des Heißgasstroms wurde eine Antenne installiert, um die ausgehenden Radiowellen zu empfangen.
Negative Spannung, positiver Effekt
Entscheidend für den neuen Ansatz zur Lösung des "Reentry-Blackouts" ist ein negatives Spannungsfeld, welches in der Nähe des Senders erzeugt wird. Durch die negative Spannung wird der ionisierte Plasmastrom umgeleitet und ein Fenster für die Radiowellen geöffnet. Dieses "Fenster" kann nicht dauerhaft offen gehalten werden. Deshalb wird die Spannung gepulst, das heißt, in kurzen Intervallen von wenigen Millisekunden erzeugt. Dies ist ausreichend, um ein Senden und Empfangen von Daten zu ermöglichen.
Bislang wurde die Methode der gepulsten Magnetfelder lediglich in numerischen Simulationen entwickelt. Die Testreihe stellt einen weiteren Schritt zur späteren Anwendung im All dar.
Krishnamoorthy zeigte sich begeistert von der unkomplizierten Zusammenarbeit: "Wir haben innerhalb von nur drei Monaten die Möglichkeit erhalten unser Verfahren hier in der Praxis zu testen und können dabei von den Erfahrungen des DLR auf diesem Sektor profitieren."
Der Leiter der DLR-Überschall- und Hyperschalltechnologie, Dr. Ali Gülhan, zieht ebenfalls eine positive Bilanz: "Die Kooperation zwischen dem DLR und der Stanford Universität bietet optimale Rahmenbedingungen, um das komplexe Problem ‚Communication Black-out‘ mit vertretbaren und systemkonformen technischen Maßnahmen zu reduzieren." 
Das getestete Verfahren wird in der Zukunft weiter verfeinert und auf seinen Einsatz in neuen und bereits bestehenden Raumfahrzeugen weiterentwickelt.

Raumfahrt - Warum leben4 Personen für 30 Tage in einem isolierten Lebensraum?. Wissenschaft!

.

This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

.

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media kids!
The only people they will talk with regularly are mission control and each other.
.
The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection.
What will they be doing?
Because this mission simulates a 715-day journey to a Near-Earth asteroid, the four crew members will complete activities similar to what would happen during an outbound transit, on location at the asteroid, and the return transit phases of a mission (just in a bit of an accelerated timeframe). This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 10 minutes each way. The crew will also perform virtual spacewalk missions once they reach their destination, where they will inspect the asteroid and collect samples from it. 
A few other details:
The crew follows a timeline that is similar to one used for the ISS crew.
They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercises.  
They will be growing and taking care of plants and brine shrimp, which they will analyze and document.
But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to maneuver through a debris field during the Earth-bound phase of the mission. 
.
Throughout the mission, researchers will gather information about cohabitation, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.
.
Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.
Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.In total, this mission will include 19 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for future missions.

Astronomie - Radioastronomie Satellit mit 15 bodengestützten Radioteleskopen erzielen zusammen höchste Bild-Auflösung

IMAGE RELEASE: Space-Earth System Produces Highest-Resolution Astronomical Image
Using an orbiting radio-astronomy satellite combined with 15 ground-based radio telescopes, astronomers have made the highest-resolution, or most-detailed, astronomical image yet, revealing new insights about a gorging black hole in a galaxy 900 million light-years from Earth. The scientists combined signals from the Spektr-R satellite of the RadioAstron mission with those from radio telescopes throughout Europe and nine antennas of the National Science Foundation's Very Long Baseline Array (VLBA). The result was an image with the resolving power of a telescope nearly 63,000 miles wide, or almost eight times the diameter of the Earth.
The image shows radio emission coming from a jet of particles accelerated to speeds nearly that of light by the gravitational power of a supermassive black hole at the core of a galaxy called BL Lacertae. The jet shown by this image would fit within the outer extent of our Solar System, marked by the Oort Cloud of cometary objects that reside far beyond the familiar planets. The image shows detail roughly equivalent to seeing a 50-cent coin on the Moon. The image appears elongated because the distance between the satellite and the ground telescopes is so much greater than that among the ground telescopes themselves, providing greater resolving power in one direction. In this version, resolution in the orthogonal direction is exaggerated to compensate.
The satellite project is led by the Astro Space Center in Moscow, and the data from all 15 telescopes were combined at a facility of the Max Planck Institute for Radio Astronomy in Bonn, Germany. The scientists are reporting on their work in the Astrophysical Journal.
The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

Raumfahrt - USA wollen ISS-Programm mit Russland bis 2024

.

US is asking for a prolongation of the International Space Station program through to 2024 since the American segment of the station cannot exist autonomously, Russian Deputy Prime Minister Dmitry Rogozin told Vesti’24 news channel on Friday. "The US does not have an opportunity to separate its segment from the ISS so that it would continue flying," he said. "The Americans don’t have an analog of our engine RD-180." "They don’t have engines as perfect, simple and inexpensive as this one," Rogozin said in a comment on the statements by US politicians Washington might stop these purchases. "They still have to buy the products manufactured in the USSR in the 1970’s or in the Russian Federation in the 1990’s since their characteristics surpass the best US samples of today."

Raumfahrt - Lift-off für das europäische Space Laser Netzwerk EDRS

.

EDRS will eventually feature several relay satellites in orbit, gathering data and speeding it to the ground
-
Europe has begun to roll out a data superhighway in orbit above the Earth.
The first node in the network is a telecommunications satellite that was launched from Baikonur, Kazakhstan.
It will use a laser to gather pictures of the planet taken by other spacecraft and then relay them to the ground.
One benefit will be to put information on natural disasters, such as flooding and earthquakes, into the hands of emergency responders far faster than has previously been possible.
Currently, it can take hours to get the pictures taken by Earth observation satellites down on the ground.
Part of the reason is that spacecraft can only transmit their images when they pass over a receiving dish, and they will have visibility of this antenna for just 10 minutes in most cases during every 90-minute tour around the globe.
The European Space Agency's (Esa) answer is to fire the pictures upwards instead, via laser, to another satellite much higher in the sky that has a constant view of the ground station.
The agency recently put up two Earth observers that are equipped with optical transmission equipment. These will now be able to offload their data through the new relay satellite, which is to be positioned 36,000km above the equator at 9 degrees East.
Testing by Esa's industrial partner, Airbus Defence and Space, shows it should be possible for the system to put pictures on the desks of the people who need them within 20 minutes of those images being acquired.
For some applications - such as the monitoring of pollution incidents, or illegal fishing or ocean piracy - the time saved could be critical to achieving an effective response.
"Some important shipping routes go through the North Pole region, where thick ice flows can cause damage to vessels and even threaten human life," explained Magali Vaissiere, Esa's director of telecoms.
"It's also an environment in constant motion which means that data that is two days old is not only unhelpful - it could even be unsafe.
"We have already demonstrated quasi real-time performance of below 20 minutes for bringing monitoring information from the coast of Brazil to the user's desk. And with this capability, the European Data Relay System (EDRS) may open up a new horizon to what I would call quasi real time Earth observation."
EDRS has been in development for more than 10 years. Getting satellites to talk to each other via a narrow laser beam is no easy task, says Esa project manager Michael Witting.
"The difficulty is basically that you have to hit another satellite with your laser beam over a distance of over 40,000km, which is akin to hitting a two-euro coin over the distance of the Atlantic," he told BBC News.
With a successful connection, data will move at a rate of up to 1.8Gbps.
EDRS will debut with the European Commission as its anchor customer. Brussels is establishing a series of satellites called Sentinels that will systematically map the Earth, to help inform and enforce EU policies.
Prodigious volumes of data are expected from these satellites in the coming years and the traditional downlink solutions are no longer regarded as adequate to the task.
The relay spacecraft is actually a standard TV platform owned by the Paris-based commercial operator Eutelsat. Esa's laser node, which it refers to as EDRS-A, is a hosted payload on this spacecraft.
The launch from the Kazakh Baikonur cosmodrome atop a Proton rocket occurred at 22.20 GMT on Friday (04:20 local time Saturday).
The drop-off high above the Earth was confirmed nine hours and 12 minutes later.
.
Planes and drones could in future fire their data up to an EDRS satellite, but only in cloud-free skies
-
Many weeks of testing lie ahead. EDRS should go into full service in the summer.
A second relay satellite carrying another laser terminal will go up in 2017. Further such platforms will be required to provide fully global, round-the-clock, super-fast connections.
Evert Dudok from Airbus said: "We are looking for partners to deliver the system. It can be a dedicated payload but it can also be a hosted payload as we have it on EDRS-A. We want to have this system operational by 2020; that's very important. And I think we can set this optical standard established here in Europe as a global standard, which would be very interesting"
The laser technology is very much a German development, led by Tesat Spacecom. Germany has invested more than 280m euros in the capability, through its own space agency (DLR) and through Esa.
Eutelsat-9B was built in large part at Airbus factories in Stevenage and Portsmouth the UK. Britain will also be a major downlink point for EDRS through a dish sited at Harwell in Oxfordshire.

Raumfahrt - Start von Proton-M mit Eutelsat 9B Satelliten

.

12.01.2016

This year's first launch from the Baikonur Cosmodrome (Kazakhstan) of Russia’s Proton-M carrier rocket that should place into orbit the Eutelsat 9B satellite, has been postponed for three days, a source in the rocket and space industry told TASS on Monday.
"The preliminary launch date is January 28," the source said. The previous launch date, he said, was January 25. The source said that the launch was postponed because the staff of the Khrunichev Centre (manufacturer of Proton-M and Breeze-m upper stage) need more time to prepare the rocket and upper stage for launch. The launch of the European spacecraft will be carried out by International Launch Services (ILS). The ILS joint venture was created in 1995 by Russia’s Khrunichev State Research and Production Space Centre and the American corporation Lockheed Martin. Ten years after that Lockheed Martin withdrew from the partnership, selling the majority stake to a German businessman. In May 2008 the Khrunichev Centre bought the stake and ILS is its subsidiary ever since. The company, based in a suburb of Washington, D.C. - Reston (Virginia), over the past 20 years has carried out more than 80 commercial launches of the Proton carrier rockets from the Baikonur Cosmodrome Russia leases from Kazakhstan.
ILS Proton Launch Services utilizes the Proton Breeze-M launch vehicle to launch and orbit commercial spacecraft. The Proton-M/ Breeze-M launcher is the latest evolution of the Proton launch vehicle that dates back to the initial launch in May 1965. The first Proton-M/ Breeze-M rocket was flown for a Russian federal mission in April 2001, and the first commercial Proton-M/ Breeze-M vehicle was flown in December 2002 with the NIMIQ 2 satellite for Telesat. Proton launch vehicles are designed and built by Khrunichev within its facility near Moscow. The Khrunichev facility is home to all engineering, assembly and test functions of the Proton launcher. With the recent consolidation of Russian space enterprises, Khrunichev has direct oversight and control of up to 70% of all Proton rocket manufacturing, including all engine systems. This consolidation directly supports Khrunichev’s ongoing efforts for vertical integration of Proton rocket production and management. International Launch Services provides commercial launch services for global satellite operators, and offers a range of services and support, from contract signing through mission management and on-orbit delivery. It also provides sales and marketing, mission and quality management, launch operations, legal, licensing and support, integration mission design, Proton manufacturing, and technical translation services.
The Eutelsat 9B satellite was built on the order of the French satellite operator Eutelsat S.A. It is manufactured by Airbus Defence and Space. The satellite’s mass is 5,175 kg and service life - 15 years. Eutelsat 9B is a high-capacity Ku-band satellite based on the Eurostar E3000 platform. It is scheduled to be launched to 9° East in 2016. The 50-transponder satellite will take 9° East to a new level of performance, increasing resources by 12 additional transponders. Capacity will be spread across five footprints, with frequency reuse significantly increasing overall bandwidth. It will be the first launch of the Proton rocket in 2016, the 92nd launch under the ILS programme, the 11th launch with a Eutelsat satellite and the 21st launch with a satellite manufactured by Airbus.

Decision to postpone Russia’s Proton rocket launch till Jan 30 not made yet — source 
 Media report said earlier on Tuesday that the launch has been postponed for two days
.
Russia’s state commission has not yet made a decision to postpone the launch of the Proton-M carrier rocket with the European communications satellite Eutelsat 9B from January 28 to January 30, a source at the Baikonur Cosmodrome from where the rocket is to be launched, told TASS on Tuesday.
Media report said earlier on Tuesday that the launch has been postponed for two days. "No decision has been made so far. There have been only proposals from the Khrunichev State Research and Production Space Centre (manufacturer of the Proton rocket and Breeze-M upper stage) to postpone the launch for two days, but no decision has been made yet. The state commission will possibly take a decision today on this launch," the source said. According to him, experts of the Khrunichev Centre have proposed to shift the launch date for replacing the solid-propellant engines of the second and third stages of Proton, "because there was no confidence in them." "There have been irregularities during their transportation from Moscow to Baikonur, so they have proposed to play it safe, replace them and postpone the launch. The new engines were delivered to the launch site yesterday," the source said. Russia’s State Corporation Roscosmos has not commented in this information so far.
The original launch date was January 25, however, was postponed until January 28. The launch was postponed because the staff of the Khrunichev Centre needed more time to prepare the rocket and upper stage for launch.

European satellite Eutelsat 9B to be launched from Baikonur at 1:20 a.m. Moscow time on Jan 30 - Roscosmos
MOSCOW. Jan 22 (Interfax) - The Russian state space corporation Roscosmos has rescheduled the launch of Russia's Proton-M launch vehicle (LV) carrying the Eutelsat 9B communications satellite from January 28 to January 30, 2016, Roscosmos has said.
"The reason for postponing the launch is unfavorable weather conditions, which have affected delivery logistics," Roscosmos said in a press release seen by Interfax on Thursday evening.
Preparations for the launch vehicle are now continuing at the assembly and testing facility.
No technical defects have been detected as the LV and the satellite are being prepared for the launch, Roscosmos said.
"The launch will be conducted from Launch Pad No. 200 of the Baikonur Cosmodrome at 1:20 a.m. Moscow time on January 30, 2016," it said.
A Baikonur source told Interfax on Tuesday that the launch of the Proton-M LV with the European satellite from the Baikonur Cosmodrome had been postponed for 48 hours.
Eutelsat 9B is a powerful Ku-band telecommunications satellite, which was built by Airbus Defense and Space using the Eurostar E3000 satellite platform. It is designed to provide digital TV and data relay services to customers in the Scandinavian and Baltic countries.
In October 2015, International Launch Services (ILS), a subsidiary of Russia's Khrunichev Space Center, and Paris-based Eutelsat Communications, one of the leading satellite operators, signed a long-term contract on Proton-M LV launch services. Several Proton-M LVs carrying Eutelsat satellites are expected to be launched from the Baikonur Cosmodrome from 2016 to 2023. Proton LVs have helped lift 11 Eutelsat satellites into orbit in the past 15 years.

 The launch of Proton-M ILV / Eutelsat-9B satellite is scheduled for 30 January 2016, at 01:20 Moscow time, marking the first Proton launch this year
.
Russia’s Proton-M carrier rocket with the Eutelsat-9B satellite of the European Space Agency has been installed on the launch pad of the Baikonur cosmodrome, the Khrunichev State Research and Production Space Center (Proton manufacturer) said in a release received by TASS on Tuesday. On January 26, the Proton-M space rocket with the Eutelsat-9B satellite was moved to the launch pad area No 200 at the Baikonur cosmodrome and lifted to the vertical position, the Khrunichev Centre reported. This morning, the Proton-M Integrated Launch Vehicle (ILV) / the Eutelsat-9B spacecraft stack was erected on the launch pad of Area 200. Specialists from Khrunichev and other space industry entities have proceeded with the operations required by on-pad Day 1 schedule, the release says.
The launch of Proton-M ILV / Eutelsat-9B satellite is scheduled for 30 January 2016, at 01:20 Moscow time, marking the first Proton launch this year. The year 2015 saw eight Proton launches. Both the Proton launch vehicle and Breeze-M upper stage were designed, and are serially produced, at the Khrunichev Space Centre. The modernized Proton-M / Breeze-M upper stage configuration is capable of providing a GTO delivery for payloads with a mass in excess of 6 MT. The upcoming launch will be performed as part of the long-term Proton M launch services contract signed in October 2015 between the International Launch Services (ILS), a Khrunichev Space Centre subsidiary, and one of the leading international operators, the Paris-based Eutelsat Communications. Over the past 15 years, as many as 11 spacecraft were launched on the Proton LV for the Eutelsat orbital group, Khrunichev said. Last week, head of Russia’s Roscosmos State Corporation for Space Activity Igor Komarov told journalists that the cost of the launch of one Russian Proton-M carrier rocket for foreign customers is about $70 million if they order five launches, "The price is around 70 million (dollars if the order is) for five launches and more", he said. According to him, the leadership of the Khrunichev State Research and Production Space Centre has managed to cut the Proton manufacturing costs by 5-7%, and taking into account last year’s inflation the figure is 15-20%. The first launch of a Proton rocket in 2016 was originally planned for January 25 but then was postponed until January 28 and then till January 30. The launch of the rocket that is to orbit the Eutelsat 9B satellite of the European Space Agency (ESA) was postponed because the staff of the Khrunichev Centre needed more time to prepare the rocket and upper stage for launch. The launch of the European spacecraft will be carried out by International Launch Services (ILS). The ILS joint venture was created in 1995 by Russia’s Khrunichev Centre and the American corporation Lockheed Martin. Ten years after that Lockheed Martin withdrew from the partnership, selling the majority stake to a German businessman. In May 2008 the Khrunichev Centre bought the stake and ILS is its subsidiary ever since. The company, based in a suburb of Washington, D.C. - Reston (Virginia), over the past 20 years has carried out more than 80 commercial launches of the Proton carrier rockets from the Baikonur cosmodrome Russia leases from Kazakhstan. ILS Proton Launch Services utilizes the Proton Breeze-M launch vehicle to launch and orbit commercial spacecraft. The Proton-M/ Breeze-M launcher is the latest evolution of the Proton launch vehicle that dates back to the initial launch in May 1965. The first Proton-M/ Breeze-M rocket was flown for a Russian federal mission in April 2001, and the first commercial Proton-M/ Breeze-M vehicle was flown in December 2002 with the NIMIQ 2 satellite for Telesat. Proton launch vehicles are designed and built by Khrunichev within its facility near Moscow. The Khrunichev facility is home to all engineering, assembly and test functions of the Proton launcher. With the recent consolidation of Russian space enterprises, Khrunichev has direct oversight and control of up to 70% of all Proton rocket manufacturing, including all engine systems. This consolidation directly supports Khrunichev’s ongoing efforts for vertical integration of Proton rocket production and management. The Eutelsat 9B satellite was built on the order of the French satellite operator Eutelsat S.A. It is manufactured by Airbus Defence and Space. The satellite’s mass is 5,175 kg and service life - 15 years. Eutelsat 9B is a high-capacity Ku-band satellite based on the Eurostar E3000 platform. It is scheduled to be launched to 9° East in 2016. The 50-transponder satellite will take 9° East to a new level of performance, increasing resources by 12 additional transponders. Capacity will be spread across five footprints, with frequency reuse significantly increasing overall bandwidth. It will be the first launch of the Proton rocket in 2016, the 92nd launch under the ILS programme, the 11th launch with a Eutelsat satellite and the 21st launch with a satellite manufactured by Airbus. The mass of the satellite is nearly 5.2 tonnes and its service life is 15 years.

WATCH THE EDRS LAUNCH
Watch the launch of ESA’s first European Data Relay System (EDRS) laser node live on 29 January. Streaming starts 20 minutes before liftoff, with launch expected at 22:20 GMT. 
EDRS is one of a kind and ESA’s most ambitious telecom programme to date, creating the means for an entirely new market in commercial satellite communications.
Dubbed the ‘SpaceDataHighway’, EDRS will uniquely provide near-realtime Big Data relay services using cutting-edge laser technology. It will dramatically improve access to time-critical data, aiding disaster response by emergency services and maritime surveillance.
Airbus Defence and Space are ESA’s programme partner and operator of the service. The first node, called EDRS-A, will begin relaying information this summer from its first customers: the European Commission Copernicus Sentinel-1 and -2 satellites. 
Once fully deployed, EDRS will relay up to 50 terabytes of data from space to Earth every day. It will eliminate the downlink delay currently prohibiting immediate access to satellite information and phase out Europe’s reliance on foreign ground stations.
