Neue „Sternbilder“ aus Gammastrahlenquellen: Astronomen taufen 21 neue Konstellationen – von Einstein bis zum Raumschiff Enterprise
Himmelsbilder im Gammalicht: Es gibt 21 neue Konstellationen am Himmel – ihre Motive reichen von der Saturn-5-Rakete über Godzilla, Einstein und dem Raumschiff Enterprise bis zu Schrödingers Katze. Mit bloßem Auge sind diese neuen Konstellationen allerdings nicht sichtbar, denn ihre Lichtpunkte bestehen aus Gammastrahlenquellen – Pulsaren, Schwarzen Löchern oder Sternexplosionen. Aufgespürt hat sie das Gammastrahlen-Weltraumteleskop Fermi der NASA.

Einstein and the Incredible Hulk Now Have Their Own Constellations (But You’ll Never See Them)
For thousands of years, humans have looked up at the stars and ordered them into constellations: the Hulk … the TARDIS … Schrödinger’s cat. Not familiar with these? That’s probably because you can’t see them without a gamma-ray telescope — and also, NASA just invented them.

ESA PR 28-2018: BepiColombo blasts off to investigate Mercury’s mysteries
The ESA-JAXA BepiColombo mission to Mercury blasted off on an Ariane 5 from Europe’s Spaceport in Kourou at 01:45:28 GMT on 20 October on its exciting mission to study the mysteries of the Solar System’s innermost planet. Signals from the spacecraft, received at ESA’s control centre in Darmstadt, Germany, via the New Norcia ground tracking station at 02:21 GMT confirmed that the launch was successful.

BepiColombo auf dem Weg zum Merkur – Europäisch-japanische Mission erforscht den kleinsten Planeten des Sonnensystems
Die europäisch-japanische Planetenmission BepiColombo hat am Samstagmorgen begonnen. Die beiden Sonden stiegen um 3.45 Uhr deutscher Zeit an der Spitze einer Ariane-5-Rakete vom Weltraumbahnhof Kourou in Französisch-Guyana auf, teilte die Europäische Weltraumorganisation ESA mit.

BepiColombo Spacecraft Launch on 7-Year Trek to Mercury for Europe and Japan
A joint European-Japanese mission to the tiniest planet, Mercury, blasted off from French Guiana on its long journey tonight (Oct. 19, Oct. 20 GMT).
That mission, BepiColombo, will spend seven years cruising toward its target, where it will separate into two spacecraft and orbit Mercury for a year — or two, if the mission is extended. The measurements taken there could not only solve lingering mysteries about the innermost planet, but also about the formation of our solar system and neighboring ones. The whole mission cost the European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) almost $2 billion, according to press reports.

Mission BepiColombo: Der lange Weg zum Merkur
Am 20. Oktober 2018 soll um 3.45 Uhr mitteleuropäischer Sommerzeit (19. Oktober 22.45 Uhr Ortszeit) die europäisch-japanische Planetenmission BepiColombo an Bord einer Ariane-5-Rakete vom Weltraumbahnhof Kourou in Französisch-Guyana ins Weltall starten. „Die Mission soll nicht nur den Planeten Merkur erforschen, sondern auch neue Erkenntnisse über unser Sonnensystem liefern“, erklärt Dr. Walther Pelzer, Vorstand für das Raumfahrtmanagement im Deutschen Zentrum für Luft- und Raumfahrt (DLR). „Einmal mehr erweist sich Japan bei dieser enormen Herausforderung als zuverlässiger Partner der Europäer in der Raumfahrt.“ Rund sieben Jahre wird die lange Reise der Sonde durch das Innere des Sonnensystems dauern.

BepiColombo’s Path: Why Does It Take So Long to Get to Mercury?
The European and Japanese space agencies launched their first mission to Mercury yesterday (Oct. 19, Oct. 20 GMT), but now, the mission’s engineers and admirers have to endure a seven-year wait before the project’s science begins in earnest. The BepiColombo mission has such a long cruise time because it’s actually really difficult to successfully orbit our tiniest planetary neighbor. It’s so difficult that it took until 1985 before an engineer figured out any way to make the orbital trajectories work out properly. The problem arises because Mercury is so small and so close to the sun.

BepiColombo: Der Transfer zum Merkur / Transfer to Mercury
Wie kommt die ESA-Merkursonde BepiColombo zum Ziel? Die optimale Transferbahn ist zugegebenermaßen micht ganz einfach auszurechnen – was aber nicht bedeutet, dass das dahinter stehende Prinzip besonders schwierig zu verstehen ist. How does the interplanetary transfer of ESA’s Mercury mission BepiColombo work? Computing the optimal trajectory arguably isn’t straightforward, but that doesn’t mean that the underlying principles are particularly difficult to grasp.

BepiColombo’s beginning ends
A stunning early morning launch lifted the ESA/JAXA BepiColombo spacecraft into space on Saturday, 20 October. This marked the start of intensive, round-the-clock flight control activities to ensure the mission’s health and functioning in the harsh environment of space. At 13:45CEST on Monday 22 October, just 58 hours into its mission, the critical first segment of the fledgeling satellite’s long voyage to Mercury was wrapped up, as teams at ESA’s mission control centre declared the critical ‘launch and early orbit phase’ complete. The end of the beginning now beckons months of extensive in-orbit commissioning activities, in which operations teams will work extended hours daily until the end of December, performing tests to ensure the health of BepiColombo’s science instruments, its propulsion and other systems.

Sojus Fehlstart / Failed launch Soyuz
RIA Nowosti: Untersuchungskommission hat Schuldige für Sojus-Fehlstart gefunden
Die Staatliche Kommission der GK Roskosmos zur Untersuchung des Fehlstarts des Raumschiffes Sojus MS-10 vom 11. Oktober und die Ermittlungsorgane haben angeblich die möglichen Schuldigen für die Beschädigung eines der Sensoren der Sojus-FG-Trägerrakete gefunden. Das berichtet die Moskauer Nachrichtenagentur RIA Nowosti unter Berufung auf eine nicht genannte Quelle auf dem Kosmodrom Baikonur in Kasachstan. „Die Schuld der konkreten Mitarbeiter ist bekannt“, schreibt die Agentur.

What It Felt Like to Be Aboard the Failed Rocket Launch to the Space Station
Everything was going smoothly — until NASA astronaut Nick Hague felt a sudden tremor. „The first thing I really noticed was being shaken pretty violently side to side,“ he said during his first publicly broadcast interviewssince his Soyuz rocket failed shortly after liftoff on Oct. 11. The rocket was meant to carry Hague and Russian cosmonaut Alexey Ovchinin to the International Space Station in what would have been the American’s first trip to space. Instead, the pair’s emergency rescue system kicked into action after a problem during booster separation.

Russian Soyuz Rocket Will Launch Astronauts to Space Station by Christmas, NASA Chief Says
The next set of crewmembers should launch toward the International Space Station in December, despite the failure of a Russian Soyuz rocket earlier this month, NASA chief Jim Bridenstine said. That failure occurred Oct. 11, causing the Soyuz spacecraft carrying NASA astronaut Nick Hague and cosmonaut Alexey Ovchinin to make an emergency landing in Kazakhstan just minutes after liftoff. The investigation into the incident has been productive, and the Soyuz rocket likely won’t be grounded for too much longer, Bridenstine said today (Oct. 23) during a meeting of the U.S. National Space Council in Washington, D.C.
„We have a really, really good idea of what the issue is,“ Bridenstine said. „We are getting very close to understanding it even better so that we can confidently launch again.“ [In Photos: Space Crew’s Harrowing Abort Landing After Soyuz Failure]

After Soyuz Abort, Russia Wants 3 Successful Robotic Flights Before Next Crew Launch
The Russian space agency, Roscosmos, initial report from its investigation into the failed Oct. 11 Soyuz crew launch should be complete by the end of this week, the agency announced in a statement released yesterday (Oct. 17). The agency’s head of human spaceflight, cosmonaut Sergei Krikalev, also said in a news conference yesterday that Roscosmos will not launch another crewed flight until three uncrewed launches are successful and the investigation’s findings have been addressed. The Oct. 11 launch was aborted a couple minutes after liftoff because of an issue with booster separation, sending the two astronauts on board plummeting back to Earth.
