Zitat Beginning Monday, the FAA said commercial space launches will only be permitted between 10 pm and 6 am local time, when the national airspace is most calm. The order restricts commercial reentries to the same overnight timeframe. The FAA licenses all commercial launches and reentries.
Zitat The planned New Glenn launch was expected to send NASA's twin Mars ESCAPADE orbiters on a winding path to the Red Planet from Blue Origin's Launch Complex 36 pad at the Cape Canaveral Space Force Station here. But throughout an 88-minute window for the launch, foul weather kept the Mars-bound mission stuck on Earth. The next attempt to fly will be Wednesday (Nov. 12). ... "Our next launch attempt is no earlier than Wednesday, November 12, due to forecasted weather and sea state conditions," Blue Origin said in a statement Sunday night. "We worked with the FAA and range to select a launch window from 2:50 PM – 4:17 PM EST / 19:50 – 21:17 UTC." A livestream of the launch will begin about 20 minutes before liftoff. You'll be able to watch the launch live on Space.com, courtesy of Blue Origin.
Blue Origin hinted Saturday that the company would work with the FAA to find a new launch date for ESCAPADE despite the federal restrictions due to the government shutdown.

Zitat The twin ESCAPADE Mars probes are scheduled to lift off atop the partially reusable New Glenn from Florida's Cape Canaveral Space Force Station on Wednesday (Nov. 12) during a nearly 90-minute window that opens at 2:50 p.m. EST (1950 GMT). It will be the second attempt for this mission; the first try, on Sunday (Nov. 9), was scrubbed due to weather.
Update for 10 a.m. ET on Nov. 12: Blue Origin is standing down from today's New Glenn rocket launch attempt due to ongoing geomagnetic storms caused by multiple coronal mass ejections from a highly energetic sunspot.
In a post on X, Blue Origin says the launch attempt was cancelled "due to highly elevated solar activity and its potential effects on the ESCAPADE spacecraft." A new launch date has not been set, but NASA and the company are evaluating launch windows based on space weather and other launch schedules.
Zitat Blue Origin@blueorigin NG-2 Update: New Glenn is ready to launch. However, due to highly elevated solar activity and its potential effects on the ESCAPADE spacecraft, NASA is postponing launch until space weather conditions improve.

Zitat Mehrere Sonnenstürme sind aktuell auf dem Weg zur Erde. Einer brachte in dieser Nacht Polarlichter bis nach Deutschland. Bis weit in den Süden waren sie sichtbar. Wann und wo sie diese Nacht nochmal sichtbar sein könnten.
Wer in der vergangenen Nacht viel Geduld hatte und lange wach geblieben ist, hatte das Glück, farbenfrohe Polarlichter bestaunen zu können. Sie reichten bis weit in den Süden Deutschlands und noch weiter. Auch die kommende Nacht verspricht sehr gute Chancen, erneut Nordlichter über Deutschland zu sehen. Wann es so weit sein kann.
Gleich drei Sonneneruptionen gab es in den Tagen vom 09. bis 11. November. Die ausgewerteten Daten zeigen eine hohe Wahrscheinlichkeit, dass Nordlichter entstehen könnten. Das Space Weather Prediction Center (SPWC) rechnete damit, dass die Sonnenstürme zwischen dem 11. und 13. November 2025 auf die Erde treffen. Heute Nacht (12.11.) ab 2:00 Uhr begann der Himmel über ganz Deutschland zu leuchten. Heute Nachmittag oder am frühen Abend des 12. November wird der nächste Sonnensturm erwartet – und dieser soll noch stärker sein. Die Chancen, wieder einen bunten Himmel in Deutschland zu sehen, sind also sehr hoch.
Zitat THE STORM IS NOT OVER: Last night's severe (G4) geomagnetic storm is subsiding, but the action is not over. Earth's magnetic field is still reverberating from a double-strike of CMEs on Nov. 11th. A third CME is expected to hit Earth on Nov. 12th, elevating storm levels back to G3/G4. If you missed the auroras last night, you might get another chance. Aurora alerts: SMS Text.
DOUBLE CME STRIKE PRODUCES SEVERE STORM: Arriving earlier than expected, two CMEs struck Earth on Nov. 11th. The closely-spaced sequence of impacts produced a severe (G4) geomagnetic storm. Auroras spread across almost every US state with sightings as far south as Florida, California, Texas, Arizona and Alabama.

Zitat „Der Sonnensturm erreichte am Dienstag um 23:38 Uhr die Erde. Er löste den bisher stärksten geomagnetischen Sturm im Jahr 2025 und den drittstärksten im aktuellen Sonnenzyklus aus. Die Stärke dieses geomagnetischen Sturms lag auf der fünfteiligen G-Skala bei G4“, sagt Christian Möstl, Leiter des Space Weather Office der GeoSphere Austria. „Die Effekte waren besonders intensiv, weil ein schneller Sonnensturm unmittelbar auf einen früheren Sonnensturm folgte und so in einer Art Windschatten die Erde noch schneller erreichte. Außerdem interagierten diese beiden Sonnenstürme kurz vor der Erde. Auch in der Nacht auf Donnerstag sind Polarlichter in Österreich möglich da im Laufe des Mittwochs ein weiterer Sonnensturm bei der Erde eintreffen sollte. Im Zuge der geomagnetischen Stürme sind Probleme mit der Positionsbestimmung mittels Globaler Navigationssatellitensysteme nicht ausgeschlossen.“
GEOMAGNETIC STORMS ARE LIKELY TODAY: Earth's magnetic field is reverberating from three potent CME strikes in past 48 hours. This is causing geomagnetic storms and widespread auroras. Currently, storm levels are bouncing between category G1 (Minor) and G3 (Strong) as solar wind blows around Earth faster than 900 km/s. NOAA forecasters say there is also a lingering chance of severe G4-class storms on Nov. 13th.
The storm was caused by two CMEs, which struck Earth in quick succession during the late hours of Nov. 11th. The CMEs were crowded so close together, they had the characteristics of a Cannibal CME--that is, strong internal magnetic fields and shock waves capable of sparking intense geomagnetic activity.

Solcher "Kannibalismus" unter ICMEs ("Interplanetary Coronal Mass Ejection", sobald sie einen Planeten treffen) tritt auf, wenn die nachfolgende Plasmasmasse mit größerer Geschwindigkeit als die vorhergehende ausgeworfen worden ist und beide verschmelzen. Das Gas darin bildet ein Plasma (um das mal so unzulässig salopp zu formulieren) und die Interaktion führt zu kompexen Magnetfeldern und Verstärkung. Die starken "Sonnenstürme" wie etwa das Carrington-Ereignis Ende August 1859 oder der Sonnensturm vom 4. August 1972 scheinen die Folge solcher Interaktionen zu sein. Zum letzteren:
Zitat The arrival time of the associated coronal mass ejection (CME) and its coronal cloud, 14.6 hours, remains the record shortest duration as of November 2023, indicating an exceptionally fast and typically an exceptionally geoeffective event (normal transit time is two to three days). A preceding series of solar flares and CMEs cleared the interplanetary medium of particles, enabling the rapid arrival in a process similar to the July 2012 solar storm.[2] Normalizing the transit times of other known extreme events to a standard 1 AU to account for the varying distance of the Earth from the Sun throughout the year, one study found the ultrafast 4 August flare to be an outlier to all other events, even compared to the great solar storm of 1859, the overall most extreme known solar storm, which is known as the "Carrington Event".[15] This corresponds to an ejecta speed of an estimated 2,850 km/s (1,770 mi/s).[16]
The near Earth vicinity solar wind velocity may also be record-breaking and is calculated to have exceeded 2,000 km/s (1,200 mi/s) (about 0.7% of light speed). The velocity was not directly measurable as instrumentation was off-scale high.[17][18]

Zitat Blue Origin is stepping back up to the plate and will take another crack at launching its 98-meter-tall (321 ft) rocket from Cape Canaveral Space Force Station on Thursday, Nov. 13.
A confluence of poor weather, an errant cruise ship in the keep out zone and a ground systems issue at the pad were roadblocks to a Sunday launch attempt. Its second attempt on Wednesday was halted because a trio of coronal mass ejections from the Sun created too high of a probability for strong geomagnetic storms.
The company founded by Amazon founder Jeff Bezos is now targeting liftoff from Launch Complex 36 during an 88-minute window that opens at 2:57 p.m. EST (1957 UTC).
Es liegt eine gewisse Ironie darin, daß der zweite Startversuch gestern durch einen Sonnensturm / koronalen Masseauswurf gestoppt worden ist. Die beiden Sonden sollen genau solche Ausbrüche erforschen - wie sie durch das (praktisch nicht vorhandene) Magnetfeld des Mars beeinflußt werden. Dazu sollen sie an den jeweils entgegengesetzten Punkten den Mars umkreisen, um somit einen "Vorher/Nachher"-Effekt feststellen zu können.
Zitat The science goals of ESCAPADE are to:[2] - understand the processes controlling the structure of Mars' hybrid magnetosphere and how it guides ion flows - understand how energy and momentum are transported from the solar wind through Mars' magnetosphere - understand the processes controlling the flow of energy and matter into and out of the collisional atmosphere
Zitat The mission marks NASA's first dual-satellite mission to another planet, and aims to create a 3D view of how the solar wind, the stream of charged particles from the sun, energizes and strips away Martian air.
"To understand how the solar wind drives different kinds of atmospheric escape is a key piece of the puzzle of the climate evolution of Mars," Robert Lillis, principal investigator for ESCAPADE and associate director for planetary science at the University of California, Berkeley's Space Sciences Laboratory, said in a statement released Wednesday (Nov. 5). "ESCAPADE gives us what you might call a stereo perspective — two different vantage points simultaneously."
Geologic evidence from ancient river valleys and water-formed minerals shows that Mars once had liquid water, which means it also had a much thicker atmosphere. But around 4 billion years ago, the planet's magnetic field, which is the invisible shield that protects a world from the sun's radiation, began to fade. Without that protection, the solar wind slowly stripped away the Martian atmosphere, leaving behind a tenuous wisp less than 1% as dense as Earth's.
Previous missions, including NASA's Mars Global Surveyor, MAVEN, and the Emirates Mars Mission Hope, have shown that Mars lacks a global magnetic field but retains patchy magnetic "bubbles" locked into its crust. However, with only one spacecraft in orbit at a time, researchers have been limited to viewing one region at a time, often hours apart.
With the ESCAPADE satellites, "we can monitor how those regions vary on timescales as short as two minutes and up to 30 minutes," Lillis said in the statement. "This will allow us to really make measurements we've never made before, and to characterize a very dynamic system in a way we couldn't characterize it before."

Steht oben bei # 30 und weiter oben im Thread. Die erste privat gebaute Mission, die zum Mars fliegen soll. Die Rakete ist von Blue Origin, die beiden Marssonden hat Rocket Lab geliefert.
3:16 MECO. 3:20 Stufentrennung. 4:05 Fairing jettison. 7:35 Start von 3 Triebwerken für die Bremszündung der Startstufe. 9.31 GELANDET!!! Steht auf der "Jaclyn". Die zweite Firma, die eine Startstufe wieder sicher gelandet hat. Hmph. Im Lifefeed werden jetzt die Telemetriedaten der 2. Stufe angezeigt. Und die machen das tatsächlich noch in Meilen. 22:20 Neuzündung von zwei Triebwerken. 22:22 SECO II. Second engine cut-off. 22:26 Im Lifefeed sind jetzt die beiden Marssonden zu sehen; gute zwei Minuten bis zum Freisetzen. T 33:46 "Blue" freigesetzt. T 34:11 "Gold" freigesetzt.
Die beiden Sonden sind zunächst unterwegs zum Lagrange-Punkt L2 zwischen Erde und Sonne unterwegs (das ist der Punkt, der in Verlängerung der Linie Sonne-Erde etwa 1,5 Millionen km entfernt liegt) um dort zu warten. Aufgrund der Störeffekte hauptsächlich des Monds beschreiben sie dort eine langgestreckte Ellipse um diesen Punkt, mit fast einer Million km großer Halbachse. Wenn sich das Startfenster für einen Hohnann-Transferorbit zum Mars Ende Oktober 2026 öffnet, wird ein Flyby-Manöver zur Erde eingeleitet, das beide Sonden auf Kurs zum roten Planeten bringt. Die Kosten für die beiden Sonden belaufen sich auf 80 Millionen $.
Der Start hier ist von Startrampe 36 in Cape Canaveral erfolgt. Der Beginn des Countdowns für den Start von ViaSat-3 durch ULA/United Launch Alliance auf Cape Canaveral, Startrampe 41, beginnt in vier Stunden.
Übrigens, als Zahlenvergleich: Die Erststufe einer Falcon 9 ist 41 m hoch und hat einen Durchmesser von 3,7 m; die Gesamthöhe liegt bei 70 Metern. Die Startstufe der New Glenn mißt 57 m, Durchmesser 7 m; Gesamthöhe beider Stufen plus Nutzlast 98 m.

The Pathfinder Mission (MK1-SN001) will be a demonstration mission, with MK1-SN002 and beyond available to payload customers. MK1-SN001 proves out critical systems, including the BE-7 engine, cryogenic fluid power and propulsions systems, avionics, continuous downlink communications, and precision landing within 100 m site accuracy, prior to the uncrewed NASA Human Landing System mission for the Artemis program.
Zitat Und die Spectrum von Isar Aerospace (auch dieses Startup ist 2018 ins Rennen gegangen) ist bei ihrem Erststart am 30. März 2025 in Andøya nach 30 Sekunden außer Kontrolle geraten und beim Aufprall auf die Meeresoberfläche ebenfalls explodiert. In Sachen „hinten knallt’s“ ist die deutsche Raumfahrt also schon einmal gut aufgestellt.
Update zur Spectrum.
Zitat German launch services provider Isar Aerospace has announced that the stages for the second flight of its Spectrum rocket have arrived at its launch facility in Norway.
Isar Aerospace launched the inaugural flight of its 28-metre, two-stage Spectrum rocket on 30 March. Less than thirty seconds after liftoff, the rocket’s Flight Termination System was triggered and the vehicle splashed down in the Norwegian Sea just metres from the launch pad, exploding on impact.
Following an investigation, the company identified an unintended opening of the vent valve, together with a loss of attitude control at the start of the rocket’s roll manoeuvre, as the cause of the failure. In September, when the findings of the investigation were made public, Isar Aerospace’s Vice President of Mission and Launch Operations, Alexandre Dalloneau, explained that the necessary corrective actions had been implemented and that the company was “eager to return to the pad soon.”
On 13 November, an Isar Aerospace update on its social channels revealed that, just over seven months after its first flight ended in a fireball, the company had returned to its launch facilities at the Andøya Spaceport in Norway in preparation for the rocket’s second flight. While brief, the update stated that the main and upper stages for the flight had arrived at the company’s launch pad and that it was “gearing up for pre-flight testing.” The update did not include an expected launch date.
Zitat The date for the first flight of the Gaganyaan programme has been revised again. ISRO is now aiming to launch the G1 mission in January 2026.
New Delhi: At the Curtain Raiser for the Emerging, Science, Technology and Innovation Conclave (ESTIC 2025) conference last month, ISRO Chairman V Narayanan indicated that the highly anticipated first mission of the Gaganyaan programme, designated as G1 will take place in December 2026. Following the successful launch of the CMS-03 communications satellite for the Indian Navy last week, V Narayanan indicated that the Gaganyaan G1 mission may be pushed to March 2026, although the teams are still aiming for a December 2025 launch. At ESTIC 2025 in Bharat Mandapam here, Narayanan revealed that ISRO is now aiming to launch the Gaganyaan G1 mission in January 2026.
V Narayanan said, “We are currently working on our Gaganyaan programme, to take our citizens to space and bring them back safely, and lot of activities are going on. In fact, I want to tell, 8,000 tests are completed till today, almost 97 per cent tests are successful, except small setbacks which we have fully understood. We are going to have three uncrewed missions, followed by the first crewed mission targeted in 2027. I don’t have any doubt, it is country’s project, not only ISRO’s project. I am 100 per cent sure it will be a grand successful mission in the first attempt itself.”
There are eight planned flights in the Gaganyaan programme, starting with G1 that will see a Human-Rated LVM3 rocket lifting an unpressurised crew module. The only occupant will by Vyommitra, a humanoid robot that acts as a test platform. Two more developmental flights G2 and G3 are planned. This will be followed by a pair of crewed missions, H1 and H2. H1 will carry one Gaganyatri, while H2 will carry two. Then there is an uncrewed autonomous docking of the crew module to the International Space Station, followed by the deployment of the first module of the Bharatiya Antariksh Station (BAS-1), that ISRO plans to execute by 2028. The final mission of the planned Gaganyaan programme in its current form is an uncrewed docking with the first module of BAS.
Zitat von Ulrich Elkmann im Beitrag #34Übrigens: beim nächsten Start der New Glenn, zurzeit geplant fürs 1. Quartal 2026...
Zitat Limp said success on New Glenn’s second flight would set the company up for a significant increase in cadence. The company is building enough hardware for “well above” a dozen flights in 2026, with the upper-end limit of 24 launches. The pacing item is second stages. Right now Blue Origin can build one per month, but the production rate is increasing.
“They’re coming off the line at one a month right now, and then we’re ramping from there,” he said of the second stages, known internally as GS-2. “It would be ambitious to get to the upper level, but we want to be hardware rich. So, you know, we want to try to keep building as fast as we can, and then with practice I think our launch cadence can go up.”
The biggest part of increasing cadence is manufacturing. That means BE-4 rocket engines for the first stage, BE-3U engines for the upper stage, and the stages themselves.
Blue Origin recovered the New Glenn first stage from last week’s flight and brought it into port on Monday. Although it looks much cleaner than a used Falcon 9 first stage, much of this is due to the use of methane propellant, which does not produce the soot that kerosene propellant does. It will take some time to determine if and when this recovered first stage will be able fly again, but if it’s not ready soon Blue Origin has a third first stage nearing completion.
Limp said the company will soon begin stacking the lunar lander (he promised photos) in Florida. After it is assembled, the lander will be put on a barge and shipped to Johnson Space Center in Houston for testing in a vacuum chamber.
“We’re getting pretty far along,” Limp said of Mark 1. “As soon as you start putting the gold foil on it, it starts looking like a lunar lander. So I can assure you, it’s coming together. Our plan is to still try to fly that in Q1, so I don’t see anything that’s keeping us from being able to do that.”
Der kleine Erbsenzähler muß sich auch mal wieder zu Wort melden. Stand heute (19.11.) und der Mission 6-94 von Starlink um 01:12 MEZ ist das laufende Jahr das mit den meisten Starts in der Raumfahrtgeschichte; der Zähler steht momentan bei 255. Davon fallen auf SpaceX 139 (davon 101 x Starlink mit, wenn ich mich nicht verzählt habe, bislang 2577 Satelliten).
Zitat von Ulrich Elkmann im Beitrag #30Blue Origin / New Glenn / ESCPADE
Update.
Zitat On November 13th, 2025, Blue and Gold, the two spacecraft Rocket Lab built for NASA and the University California Berkeley Space Sciences Lab’s ESCAPADE mission to Mars, were successfully launched to a high orbit barely captured by Earth’s gravity. In the days that followed, our spacecraft operators methodically worked their way through spacecraft commissioning, a process that gets all subsystems on the spacecraft up and running. This includes stabilizing the spacecraft orientation, deploying solar arrays, and powering up flight computers, multiple antennas, guidance and navigation sensors and actuators. In addition, we’ve been testing all the various modes and orientations we’ll use over the mission, as well as testing both the ‘A’ and ‘B’ redundant sides of the spacecraft that provide long-term mission resilience. Finally, our team began preparing the propulsion systems for the Blue and Gold for TCMs, or Trajectory Correction Maneuvers. This is the process of igniting the spacecraft engines for short duration burns to slightly adjust the spacecraft trajectories to ensure they’re on a perfect path to Mars.
Nominally, 29 burns are planned to get us to Mars, then another eight will be executed to adjust our orbits around the planet. Once Blue and Gold are in orbit around Mars, a few more station keeping burns will be needed to counter orbital decay that happens when the Martian atmosphere slowly decreases the spacecraft velocities through friction. But the duration of these burns, whether they're executed on the hypergolic main engine or on the cold gas reaction control system, and even whether we skip them altogether, depends on how accurate the initial orbital insertion from launch was, and how close the later burns are to our expectations. ...
But before all of that, we need to fire those engines up for the first time. Here's an overview of the current planned TCMs, though the dates and durations are subject to change:
Trajectory Correction Maneuver 1 (TCM-1): Expected date: December 2nd 2025 on Blue, December 8th 2025 on Gold 15 seconds long, consuming 2 kg of propellant to deliver 11.5m/s of delta V.
This is our initial demonstration maneuver to verify all systems perform as expected. Our fault management limits will be at their tightest to be conservative, based on margined modelling of how we expect the systems to perform.
Once it's executed, we'll update our engine performance models including Isp, or specific impulse, (i.e. fuel efficiency), thrust, and mass flow rates, as well as parameters specifying system performance such as temperatures, pressures and flow.
Trajectory Correction Maneuver 2 (TCM-2): Expected date: December 11th 2025 on Blue and December 16th 2025 on Gold 257 seconds long, consuming ~33 kg of propellant to deliver 200m/s of delta V.
This is the big one. After we execute this burn, we will recalculate our mass margins and determine exactly how much mass we can bring to Mars. There are always small variations and tolerances in every design. So far, we have assumed the lowest design performance for the system and now we get to see just how much margin we have. The better our manufacturing, the more fuel we have in reserve to extend the science mission for as long as possible at Mars, enabling the UCB-SSL team to gather more data, giving scientists and researchers greater insights. For example, the efficiency of an engine is characterized by its Isp, measured in units of seconds. A few seconds more Isp (1% more Isp) could result in allowing us to bring 20kg more propellant at Mars, enough for half a year of station keeping in orbit.
Although this is a longer burn, we have room to adapt to any contingencies should it not go perfectly. Burning a few seconds short is easily fixable on the next trajectory correction maneuver. But if we don’t... that’s equivalent to missing Mars by 100,000 km.
Trajectory Correction Maneuver 3 (TCM-3): TCM-3 is tentatively planned as a final clean-up maneuver, but it may not be needed (10 m/s or less). TCM-3 is the last maneuver that Rocket Lab will be operating directly. Once it's complete (or if it gets skipped), we'll hand off control to the team at Berkeley to operate the rest of the mission, but we’ll be cheering them on all the way to Mars!
Although TCM-3 is the last time Rocket Lab will be operating an engine maneuver, Blue and Gold still have some critical ones ahead. After patiently loitering in orbit at the Earth-Sun Lagrange Point 2 for around a year, Blue and Gold’s engines will ignite once again for a Trans-Mars Injection burn in November 2026, then after a 10 month cruise to the Red Planet they’ll undertake the Mars Orbit Insertion maneuvers in September 2027. Rocket Lab will be providing support to UC Berkeley for these two critical maneuvers.
