Transferring the International Space Station into the future

(July 1, 2024)

The International Space Station is the largest, most complex and most important element of space infrastructure yet deployed, and one of the most incredible engineering accomplishments in human history. It is the result of an international, diplomatic initiative reconciling in space the Western world and the Eastern world by combining the two space stations until then planned separately by each side – Space Station Freedom and Mir 2 – involving five major partners, the United States, Europe, Japan, Canada and Russia.
(…)
For example, to move the ISS from its present 400-kilometer altitude to an 800-kilometer altitude circular orbit requires a boost of about 220 meters per second, about the same as required for precise deorbit control. At the higher altitude, the orbital lifetime would be many decades, providing ample time for future generations to take their own decisions and actions.
(…)
We are not in charge anymore, but our question to the current generation is: since the boost stage must be built anyway, would it not be better to use that stage to place the ISS in a higher orbit for the possible use of a future generation than to destroy it upon reentry?

Jean-Jacques Dordain, who was the director general of the European Space Agency when the station was being built, and former NASA administrator Michael Griffin say its life should be extended instead, giving future scientists a chance to continue studying outer space.

Unser System: Das Ende der zivilen Europäischen Weltraumfahrt

(July 21, 2008)

DIE ISS: KALT SABOTIERT UND IN DER SACKGASSE

NASA-Chef Michael Griffin hat selbst die Entwicklung des „Space Shuttle“ und der Internationalen Raumstation ISS als „einen Fehler“ („a mistake“) bezeichnet. Erst nach verblüfften Protesten aus der Wissenschaft zog er halbherzig zurück. Aber mehr und mehr fragen sich die Beobachter aus Wissenschaft und Weltöffentlichkeit, ob man es mit einem neuen „Wettrennen im Weltraum“ zu tun hat, welches eher militärisch motiviert ist.

An ISS und Space Shuttle (siehe Screenshot, aus einem Bild der ESA) wird kritisiert, dass sie keinen „Gewinn“ abwerfen. Auf den ersten Blick einfach grosser Quatsch. Auf den zweiten skrupelloses Kalkül. Man will die zivilen Projekte einfach loswerden und denkt sich eine entsprechend dumme Luftblase aus, um diese dann testweise in die Öffentlichkeit zu setzen, dann entweder bei entsprechendem Geschrei zurückzuziehen und wegzuheucheln oder einfach immer weiter mit dem Abbau der zivilen Wissenschaft zu machen bis alles zerstört, runiert und endlich verloren ist.

Einfacher Hintergedanke: wenn man einen Krieg führen will, braucht man einen Feind, keinen Mitmenschen auf irgendeinem Planeten mit dem man dies und das gemeinsam hat. Das verwirrt nur die blöde Hammelherde die man an die Front quatschen will.

Die ISS, obgleich nicht mal fertiggebaut, steht ab 2010 ohne Versorgungsfähre da, weil die NASA auch die Space Shuttles einmottet und seit den 70er Jahren, unter den 8 Jahren Ronald Reagan mit seinem Vize George Bush, dessen 4 Jahren als Präsident, 8 Jahren Bill Clinton und dann noch 8 Jahre George Bush Junior oben drauf, kein Nachfolgemodell entwickelt hat.

Den für 2015 in Aussicht gestellten US-Raumgleiter „Orion“ darf man nicht als schlechten Witz bezeichnen, man muss es. Er besteht nur auf dem Papier, ebenso wie die notwendige Trägerrakete Ares.
Beide Luftnummern sollen im Rahmen dieses wohlklingenden „Project Constellation“ angeblich aus uralten Komponenten des „Apollo“-Programms, ja sogar aus der steinzeitlichen Delta-IV Rakete (ausgerechnet von Boeing) zusammen gesetzt werden.

Deshalb müssen ab 2010 nun zur Versorgung der ISS die Russen einspringen – mit den uralten Kapseln der Sojus-Kapseln. Es ist zum Verzweifeln.
Und ab 2015, so drohte NASA-Chef Griffin indirekt, ist das Projekt ISS sowieso hinfällig.

Auch nicht die ESA, die kanadische oder die japanische Raumfahrtbehörde machen z.Z. irgendwelche Anstrengungen um die Zukunft der einzigen Raumstation der Menschheit im All zu retten.
Dabei werden dann wirre Pläne über Mond- und Marsmissionen in die Welt gesetzt die völlig irreal und nicht umzusetzen sind, weil bei immensen technischen und infrastrukturellen Problemen trotzdem alle gegeneinander arbeiten und vor einander warnen, besonders vor den Chinesen welche zwar auffällig zielstrebig und fleissig ihre Raumfahrt selbstständig ausbauen, aber gerade mal ihren ersten Taikonauten ins All gebracht haben und noch mindestens 10 Jahre hinter dem Stand der Russen und Amerikaner sind.

Und die Franzosen? Sie hatten schon Mitte der 70er Jahre die Pläne für den Raumgleiter „Hermes“ in der Schublade, die natürlich konsequent nicht umgesetzt wurden.
1987 wurde dann endlich der erste Schritt getan, um das ganze Programm dann 6 Jahre später wieder einzustellen, ausgerechnet mit der Explosion der Challenger-Raumfähre als Begründung, die bereits 1986 erfolgt worden war.
Einerseits müsse man jetzt wohl doch Schleudersitze einbauen (was für ein Witz), deswegen könne man weniger Astronauten und Fracht mitnehmen, ausserdem habe man kein Geld und ausserdem brauche man eh keine Raumfähre.

Jetzt von einer Mondfahrt, oder gar einer Reise zum Mars zu erzählen, ist irrational und unwissenschaftlich. Letzteres ist mit normalen Verbrennungstechniken bzw. chemischen Triebwerken sowieso nicht zu schaffen, und der Ionenantrieb, dessen erste Entwürfe vom deutschen Hermann Oberth aus den 20er Jahren stammen, dümpelt leise vor sich hin. Funktionieren tut er nur im Vakuum, nicht in der Atmosphäre. Starten könnte man nur von einer Raumwerft, deren Anfang wäre erst einmal eine orbitale Station, die aber wird gerade versenkt, usw.

Man erzählt das Eine und macht genau das Andere.
Das ist keine Wissenschaft. Das ist Politik.

Raumfahrt: Musk, die ISS und die gestrandeten Astronauten

(February 22, 2025)

Der ehemalige Astronaut Ulrich Walter bringt einen weiteren Player ins Spiel: „Die Inder haben auch ein bemanntes Raumfahrtprogramm, und falls die USA als Partner wegfallen, würde ich eine langfristige Zusammenarbeit mit den Indern empfehlen.“

Klar ist: Auf unabsehbare Zeit hat Europa keine eigene Rakete und kein Raumschiff, um selbst Astronauten in den Weltraum zu bringen. Wenn früher als geplant auch noch die ISS wegfällt, könnte es für ESA-Astronauten düster aussehen.

NASA’s Laser Communications Relay: A Year of Experimentation

(Jun 28, 2023)

The Laser Communications Relay Demonstration (LCRD) uses infrared light, or invisible lasers, to transmit and receive signals rather than radio wave systems conventionally used on spacecraft. Infrared light’s tight wavelengths allow space missions to pack significantly more data – 10 to 100 times more – into a single transmission. More data means more discoveries.

Now, at the halfway point in its experimentation phase, LCRD has shown laser communications’ significant advantages over traditional radio wave systems.

5 Spacecraft Are Leaving The Solar System. What Did They See In Their Journey?

Pioneer 10: Pioneer 10 was launched in 1972 to explore the planets of the solar system. It achieved the first flyby of Mars, the first trip through the asteroid belt, and Jupiter‘s first flyby. It was the first time NASA had used nuclear energy to power its spacecraft. So, after Pioneer 10 passed Jupiter in 1973, it still had ample energy to keep going. Initially planned for 21 months, it continued to communicate with Earth for a total of 30 years.

What Spacecraft Will Enter Interstellar Space Next?

(January 30, 2019)

This milestone — reaching interstellar space — can be considered leaving the solar system by a certain definition. Let‘s be clear about what that entails. In 1990, the New York Times reported that Pioneer was reported to leave the solar system when it flew past Neptune‘s orbit. That‘s not what Voyager 2‘s scientists used to make their determination, however. Instead, the more recent measurements consider the crossing of the sun‘s heliopause, the theoretical boundary to its heliosphere, to be the determining factor for entering interstellar space. The heliosphere is a bubble of charged particles created by and flowing past the sun. Scientists use it to mark where interstellar space begins.

Raumsonde „Pioneer 10“ 40 Jahre aus Sonnensystem heraus

Am 13. Juni 1983 durchflog „Pioneer 10“ die Umlaufbahn des Neptun und wurde so laut NASA zum ersten menschengemachten Raumschiff, das am weitestentfernten bekannten Planeten unseres Sonnensystems vorbeiflog. Neptun ist im Mittel etwa 4,5 Milliarden Kilometer von der Sonne entfernt.

Mit „Pioneer 11“ und den beiden „Voyager“-Sonden folgten später ähnliche Missionen. „Voyager 1“ überholte „Pioneer 10“ schließlich als am weitesten von der Erde entferntes menschengemachtes Objekt. Zum bisher letzten Mal schickte „Pioneer 10“ im Jänner 2003 Daten, ein Kontaktversuch im März 2006 scheiterte.
