#226 RE: New Shepard Antworten

Nachtrag New Shepard.

Zitat
A single hydrogen-fueled BE-3 engine powered the 60-foot-tall (18-meter) booster off the launch pad. About a minute after liftoff, as the rocket neared supersonic speed, the plume from the BE-3 engine appeared to change color and shape, then the powerplant appeared to shut down, causing the rocket to tilt off its planned trajectory at an altitude of around 28,000 feet (8,500 meters).

The solid-fueled abort motor on bottom of the crew capsule fired immediately, delivering some 70,000 pounds of thrust to push the craft away from the failing rocket.

The four-ton capsule spun around and tumbled after the abort motor’s brief firing, which propelled the vehicle hundreds of feet away from the New Shepard rocket. Guided by reaction control system thrusters, the capsule’s motion stabilized as it deployed three drogue parachutes and three main chutes for a relatively gentle ride back to the ground. The capsule was designed to touch down at a speed of around 3 mph (5 kilometers per hour).

The NS-23 mission was initially set to launch Aug. 31, but poor weather forced the company to call off launch attempts on three consecutive days. Officials then rescheduled the launch date for Monday, Sept. 12.

The booster and capsule flown Monday were dedicated to flying science and research payloads to space, according to Blue Origin. The company’s crew-configured rocket and capsule are undergoing refurbishment for a future flight.

SpaceX successfully launches Starlink mission on sixth try

SpaceX launched a Falcon 9 rocket from Cape Canaveral Sunday night after five days of weather delays, hauling 54 more Starlink satellites to orbit as the company continues its push toward completing more than 60 missions this year.

Liftoff of the 229-foot-tall (60-meter) Falcon 9 rocket occurred at 8:18:40 p.m. EDT Sunday (0018:40 GMT Monday) to begin SpaceX’s Starlink 4-34 mission. The Falcon 9 took off powered by nine kerosene-fueled Merlin 1D engines, firing into a nighttime sky as it soared northeast from pad 40 at Cape Canaveral Space Force Station.

The mission finally got off the ground after five days of delays, which began Tuesday night when the launch team called off a countdown just before starting to load propellants into the Falcon 9 rocket. Lightning flashes lit up the sky over Florida’s Space Coast throughout the evening. Similar weather conditions Wednesday night forced officials to call another scrub before tanking, and SpaceX stopped the countdown at about T-minus 30 seconds Thursday night as weather remained “no go” for launch.

It was a similar story Friday night as SpaceX loaded propellants into the Falcon 9, but stopped the countdown just inside of T-minus 60 seconds. Teams initially targeted another launch attempt Saturday, but SpaceX announced Saturday evening the mission would be delayed to Sunday night.

This flight marked SpaceX’s 42nd Falcon 9 launch so far in 2022. It was the 40th space launch attempt overall from Florida’s Space Coast this year, including launches by SpaceX, United Launch Alliance, and Astra.

Falls sich jemand fragt, warum ich einen Beitrag zu den Unruhen nicht nur in Teheran, sondern mittlerweile im ganzen Land nicht in einen eigenen Strang stelle, sondern hierher:

Zitat von Guardian, Sep 24, 2022
Protests spread in Iran as President Raisi vows to crack down

Demonstrations that began with death of Mahsa Amini while detained by morality police pose biggest threat to regime in 13 years

Iran’s president has vowed to “deal decisively” with protests that are gathering momentum across much of the country one week after the death of a woman in custody who had been detained by the morality police.

Demonstrations have spread to most of Iran’s 31 provinces and almost all urban centres, pitting anti-government demonstrators against regime forces, including the military, and posing the most serious test to the hardline state’s authority in more than 13 years.

President Ebrahim Raisi on Saturday blamed conspirators for inciting unrest and pledged to crack down on “those who oppose the country’s security and tranquility”. Up to 35 people have been killed during clashes with security forces, according to rights groups outside Iran. Iranian officials say five security personnel have also died, trying to quell outrage surrounding the death of Mahsa Amini, 22.
...
The demonstrations have evoked images of an anti-government protest in 2009, known as the green revolution, that followed contentious presidential elections and marked the last time citizens faced off against security forces on a large scale.

“The main difference between the current protest compared to the green movement in 2009 is that now people are fighting back; they are not afraid of the brutal regime,” said Sima Sabet, an Iranian journalist. “Demonstrators are now burning ambulances because the government is using ambulances to move their security forces not to rescue people. The protesters are now using different tactics; they move between all cities and make it hard for security forces to control all locations.”

“Now we’re seeing not only big cities, but smaller cities that we’ve never seen before. We’re now also seeing unprecedented ways in which people are showing up, in the messaging and the boldness. Things are a lot more unified.”

Mahmoudi said chants heard at rallies, such as “We’ll support our sisters and women, life, liberty”, had been heard around the country.

“This is unprecedented for us. We have never seen women take their hijab off in mass like this. Burning down the police centres, running after their cars, burning down the pictures of Khamenei,” she said.

Damit es nicht untergeht:

Zitat
Another group of 52 Starlink internet satellites rocketed into orbit Saturday night from Cape Canaveral on top of a Falcon 9 launcher, continuing deployment of SpaceX’s global broadband network now accessible from all seven continents.

With 52 more satellites on the way to join the constellation Saturday night, SpaceX will move closer to fully deploying its initial fleet of 4,400 Starlink spacecraft. After Saturday night’s mission, SpaceX will have sent 3,399 Starlink satellites into orbit, including prototypes and failed spacecraft. The company currently has around 3,000 functioning Starlink satellites in space, with about 2,500 operational and another 500 moving into their operational orbits, according to a tabulation by Jonathan McDowell, an expert tracker of spaceflight activity and an astronomer at the Harvard-Smithsonian Center for Astrophysics.

The launch Sunday night, designated Starlink 4-35, is SpaceX’s 43rd launch of the year.

The Starlink 4-35 mission is the fourth Falcon 9 mission of the month. SpaceX is tentatively planning one more Falcon 9 launch with additional Starlink satellites before the end of September, but that schedule hinges on potential impacts from soon-to-be Hurricane Ian, which is forecast to threaten Florida next week.

MISSION STATS:
177th launch of a Falcon 9 rocket since 2010
185th launch of Falcon rocket family since 2006
4th launch of Falcon 9 booster B1073
152nd Falcon 9 launch from Florida’s Space Coast
98th Falcon 9 launch from pad 40
153rd launch overall from pad 40
119th flight of a reused Falcon 9 booster
62nd dedicated Falcon 9 launch with Starlink satellites
43rd Falcon 9 launch of 2022
43rd launch by SpaceX in 2022
41st orbital launch attempt based out of Cape Canaveral in 2022

Wie schon einmal in diesem Zusammenhang angemerkt: wenn man die Privatwirtschaft machen läßt, dann kann sogar Chruschtschows Vision, "Raketen wie Würstchen zu produzieren", wahr werden.

Zitat von Ulrich Elkmann im Beitrag #31
Kleine Suche nach "советские заводы могут производить ракеты, как сосиски" (ich hatte zunächst nach колбаски statt сосиски gesucht), zeigt, daß das Zitat auch im Russischen ohne Datum & Ort herumschwirrt: "seit dem Start von Sputnik 1," "auf dem Höhepunkt des Kalten Kriegs..." und ähnlichem). Es dürfte sich somit um eine kolportierte Wendung handeln, die so nie gefallen ist, aber als Stafette immer weitergereicht wird, à la "Equal goes it loose."

PPS. Die taz meint, der Satz sei 1958 nach einem Besuch im Kombinat Южмаш / Juschmasch gefallen, die neben Traktoren auch Mittelstreckenraketen produzierten; aber auch da geben die russischen Quellen nichts her.

A pair of TV broadcasting satellites for Intelsat are buttoned up for launch aboard a SpaceX Falcon 9 rocket from Cape Canaveral. SpaceX aborted a countdown Thursday due to a small helium leak, then called off another launch attempt Friday evening for allow time for additional vehicle checkouts. Another launch opportunity is set for 7:05 p.m. EDT (2305 GMT) Saturday.

The launch attempt Thursday night automatically aborted at T-minus 30 seconds after the Falcon 9’s on-board computer, which controls the final minute of the countdown, detected a higher than expected pressure decay rate in the first stage’s helium system.

“Tiny helium leak (just barely triggered abort), but we take no risks with customer satellites,” tweeted Elon Musk, SpaceX’ founder and CEO. “Standing down to investigate.”

In the next 1.5 months, SpaceX will expend 3 of their Falcon boosters: Falcon Heavy Center Core B1066, Falcon 9 B1051 and B1049. This will be the first time SpaceX will deliberatly expend a booster since the Crew Dragon Inflight Abort Test in January of 2020.

B1066 is up first. It is a Falcon Heavy Center Core and will be expended on it's 1st flight. It will launch the USSF-44 mission, scheduled for October 28th. The USSF-44 payload will be deployed directly into Geostationary Orbit, thus requiring the Center Core to be expended.

Then on November 5th, B1051 will be making it's 14th and final flight. It will be launching the Galaxy 31 & 32 satellites to GTO. Due to the weight of the satellites, a droneship recovery isn't able to get the apogee to the GEO belt, while an expendable launch is able to do so.

B1051 has previously flown 13 missions, 10 of which were Starlink. It debuted on the Demo-1 mission, the 1st launch of SpaceX' Crew Dragon capsule. It further supported the Radarsat Constellation Mission on it's 2nd flight and SXM 7 on it's 7th flight.

Last will be B1049. It will support the Eutelsat 10B (potentially with iSpace Hakuto-R rideshare) mission, which can occur NET November 11th. Due to the added weight of the lunar lander, an expendable launch is required to get the payload as close to it's destination as possible.

Notable about this launch is that B1049 will be flying with an older Block 4 specification interstage. This likely is a spare which never got to fly to space. This is because B1049 donated it's interstage to B1052. This will allow SpaceX to keep reusing the newer interstage.

B1049 has previously supported 9 mission. Eutelsat 10B will be it's 10th. It debuted on the Telstar 18 Vantage mission, and then supported the Iridium-8 mission next. Since then is has only supported Starlink missions, including the 1st ever Starlink launch and 1st Group-2 launch

Die chinesische Raumstation gibt es auch noch. Start des 3. Moduls morgen.

China to launch Mengtian science module to Tiangong space station

China plans to launch its second space station module of the year aboard a Chang Zheng 5B rocket Monday. The Mengtian module is scheduled for liftoff at 07:37 UTC, completing the initial phase of construction for China’s Tiangong space station.

The launch of the Mengtian Laboratory Cabin Module, meaning “Dreaming of the Heavens,” follows the successful addition of the Wentian module to China’s Tiangong station on July 24. Like Wentian and the Tianhe core module that was launched in April 2021, Mengtian will ride into orbit aboard China’s Chang Zheng 5B (CZ-5B) rocket, also known in English as the Long March 5B.

With a mass of about 20,000 kg, a length of 17.9 meters, and a diameter of 4.2 meters, Mengtian will provide space for science experiments in zero gravity, an airlock for exposure to the vacuum of space, and a small robotic arm to support extravehicular payloads.

China also plans to launch Xuntian, the Chinese Survey Space Telescope (CSST), in December 2023. While not a part of the Tiangong space station itself, this is designed to operate in an orbit close to that of the station, allowing it to be docked occasionally for maintenance.

The telescope has a mass of 15,500 kg and is equipped with a two-meter primary mirror that will allow for a field of view 300-350 times larger than Hubble. The expectation is that it will image up to 40% of the sky using a 2.6 gigapixel camera over its operational lifespan of ten years. It will be operated by the Chinese National Space Administration (CNSA).

Mengtian will launch aboard a Chang Zheng 5B rocket. The Chang Zheng 5 series are the most powerful rockets in China’s current fleet. Standing 56.97 meters tall and measuring five meters in diameter, the rocket’s core stage is augmented by four CZ-5-300 boosters that each feature two YF-100 engines. Each booster produces 2,400 kN at sea level, bringing the full thrust of the rocket at liftoff to 10,620 kN. The boosters provide most of the thrust during the early stages of flight, with the longer-burning core stage acting as a sustainer and continuing to burn until orbit is achieved.

The version used for this launch is the Chang Zheng 5B. This specification does not feature the CZ-5-HO second stage used on other versions and is used to lift very heavy payloads into low Earth orbit (LEO). Three of its four launches to date – including Monday’s – have been dedicated to the assembly of the Tiangong space station, whose modules are the heaviest payloads China has launched to LEO.

3/3) Different from the relocation of #Wentian, which happened ~2 months after docking, the relocation of #Mengtian will happen soon (not sure how soon), before the occupancy of Shenzhou-14 astronauts.

Final module docks at China’s Tiangong space station

Mengtian used its own propulsion to match orbit and rendezvous with the Tiangong space station—currently in a roughly 380 by 387-kilometer orbit—and connected with a forward port on Tiangong’s docking hub just under 13 hours after launch at 4:27 p.m. Eastern, China’s human spaceflight agency, CMSA, confirmed.

The new experiment module joins two earlier modules: the Tianhe core module and Wentian experiment module. Mengtian will soon be transpositioned to the port docking ring to complete the T-shaped arrangement of the space station. Wentian was transpositioned to the starboard docking ring in late September.

Mengtian (“dreaming of the heavens”) is a 17.9-meter-long, 4.2-meter-diameter and roughly 22-ton module designed to host a range of science experiments with areas of research including fluid physics, combustion and materials science and space technologies.

It has a total volume of nearly 110 cubic meters, including around 32 cubic meters available for use by astronauts, according to CMSA.
