Boeing postpones Starliner spacecraft test flight to 2022 – the clare people http://satswiss.com/boeing-postpones-starliner-spacecraft-test-flight-to-2022-the-clare-people/ Wed, 22 Sep 2021 14:27:41 +0000 http://satswiss.com/boeing-postpones-starliner-spacecraft-test-flight-to-2022-the-clare-people/

After a series of setbacks to perform the orbital test (OFT-2) with Boeing’s Starliner spacecraft, it is likely that the launch will not take place until 427474. The engineering team are still working to resolve the failure. of the spacecraft’s valve, and the official launch schedule for the next few weeks puts OFT-2 even further off the horizon this year.

  • Boeing discovers anomalies, indefinitely postpones Starliner spacecraft test flight
  • United Launch Alliance will no longer market the historic Atlas V rocket
  • Boeing to launch Starliner spacecraft to ISS in November, but manned flight only in 2022

In early August, Boeing had to cancel the launch due to problems with the valves in the ship’s propulsion system, with only a few minutes to launch the ship. While engineers are still trying to resolve this issue, Kathy Lueders, chief executive of NASA’s human exploration and exploitation mission, said the test would be more likely to take place next year. , but that the company and the space agency had not yet found a solution. a. decision.

Boeing and NASA are evaluating whether they will use another service module in Starliner to complete the OFT-2 mission or whether they will continue to try to resolve the failures of the current one. According to Lueders, the final choice should emerge in the coming weeks. The spacecraft was developed as part of the US Space Agency’s commercial crew program to transport astronauts to the International Space Station (ISS) – the same program that SpaceX and its Crew Dragon spacecraft already have.

SpaceX has already launched three manned missions to the ISS (Demo-2, Crew-1 and Crew-2) and is preparing for the fourth, which should take place next month (Crew-3). Meanwhile, Starliner has yet to travel to the unmanned ISS to prove that it is capable of transporting people safely. During Boeing’s first attempt, in 660, the spacecraft suffered a series of glitches in its software and was unable to reach the necessary trajectory to get to the ISS.

Video shows SpaceX tourists opening spaceship’s glass dome for the first time http://satswiss.com/video-shows-spacex-tourists-opening-spaceships-glass-dome-for-the-first-time/ Tue, 21 Sep 2021 21:07:53 +0000 http://satswiss.com/video-shows-spacex-tourists-opening-spaceships-glass-dome-for-the-first-time/

“Holy shit.”

Pod bay doors

After much waiting, we finally get to some of the footage recorded during last week’s all-civilian historic flight into orbit.

Sian Proctor, SpaceX Tourism and Scientific Communications Specialist shared a video of a truly treasured moment: the first time the Inpsiration4 crew were able to open the massive glass dome hatch of the Crew Dragon – a “true highlight of the Inspiration4 mission,” according to Proctor.

Mind blown

To foster a more compelling tourist experience, SpaceX decided to replace the Crew Dragon docking module, normally used to dock with the International Space Station, with a massive glass dome or “cupola”.

About 20 minutes after last week’s launch, the crew were able to open the hatch for the first time – and the video speaks for itself. Cancer survivor and crew member Hayley Arceneaux appears to be speechless towards the end of the film.

“Holy shit,” former Space Camp advisor and crew member Chris Sembroski could be heard mumbling in the background.

Epic moment

The crew also decided to play “Also sprach Zarathustra”, composed in 1896 by Richard Strauss, while opening the hatch. The coin was used in the sci-fi epic “2001: A Space Odyssey”.

So there you go, folks: the best publicity SpaceX could possibly ask for for its space tourism business. Let’s just hope they fix this toilet problem for next time.

In most cases, communication delays between the International Space Station crew and the ground are mainly due to the fact that they are routed from one tracking and data relay satellite to another while the station is orbit about 250 miles above Earth. Not noticed. NASA is not aided by NASA’s Johnson Space Center mission control center as NASA prepares to explore the moon about 240,000 miles away, and ultimately Mars, about an average of about 245 million miles away. We are developing tools to increase the autonomy of astronauts operating space vehicles and systems. In fact, in Houston, communication delays from land are prolonged.

The T2 Augmented Reality (T2AR) project is scientific and scientific by the station crew Exercise equipment It is important to maintain crew health and achieve research goals without the support of ground crews.

Astronaut Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA) has been tasked with maintaining the T2 conveyor belt, one of the space station’s crew exercise equipment, in order to start activities T2AR in orbit in April. I did. The inspection procedure is generally available as a PDF document accessible on your computer or tablet. It can also be difficult to hold when using tools, flashlights, or inspecting equipment in tight spaces. This time all the information was easy to understand, so no further instruction or communication with the mission control ground crew was required. Using Microsoft’s HoloLens augmented reality (AR) glasses and equipped with new procedural tracking software developed by NASA, Noguchi has step-by-step advice and hints to help you work without looking at another screen. I did.

T2AR will enable astronauts to perform unaided maintenance and inspection of key crew support equipment for the first time in space by combining HoloLens with custom AR software. The study is based on a sidekick experiment conducted by former NASA astronaut Scott Kelly in 2016.

In this new demonstration, 3D landmarks were used to direct the astronaut’s line of sight to the appropriate work site and provide step-by-step instructions. The aircraft walked through the steps according to the astronaut’s verbal instructions and displayed AR landmarks and step texts on the hardware based on the steps in progress. The system also provided additional information such as instructional videos and system overlays to help perform the procedure.

“AR tools promise pre-package advice and expertise,” says Brian Dunsbury, quasi-scientist at the Johnson International Space Station. “The space station is the perfect platform to test AR systems and improve these tools so that future astronauts can use them immediately when they need them. These tests bring you closer to home. And will help you mature your software and AR technology, and you’ll have remote access to your expertise and support. Locations around the world. “

Since his early work with Noguchi, ESA (European Space Agency) astronaut Thomas Peske and NASA astronaut Megan MacArthur have also used AR applications on space stations. The test provided researchers with information on how the technology worked and did not work to aid crew inspection and maintenance procedures. After this maintenance work is completed, there will be nine additional test sessions remaining in the technical demonstration plan.

While this demonstration was currently limited to critical T2 conveyor belts, the platform was designed to be used for a variety of space station needs in the future, improving crew efficiency and aircraft accuracy. execution of activities. In addition to being used in space At the station, this technology assists astronauts on their future journeys to the Moon and Mars, where communication delays are high, by allowing astronauts to perform tasks without waiting other instructions from Earth. There is a possibility.

NASA’s Advanced Exploration Systems division is sponsoring this technology demonstration aboard the Microgravity Laboratory to advance future human and robotic exploration missions as part of NASA’s lunar and martian exploration approach.

T2AR is the first operational use in space of the HoloLens in combination with custom AR software, which allows an astronaut to perform unattended maintenance and inspections on a major piece of crew support equipment. This investigation builds on the Sidekick experiment that former NASA astronaut Scott Kelly conducted in 2016.

This new demonstration used 3D directional cues to direct the astronaut’s gaze to appropriate work sites and displayed procedural instructions. The aircraft followed an astronaut’s verbal instructions to navigate the procedures and displayed AR cues and procedural text on the equipment, depending on the stage of the current procedure. The system also provided additional information, such as instructional videos and system overlays, to aid in performing the procedure.

“AR tools promise to allow us to pre-pack advice and expertise,” said International Space Station associate scientist Bryan Dansberry at Johnson. “The space station is the perfect platform to test AR systems and refine these tools so that they are ready when future astronauts need them.

Solar electric propulsion launches NASA’s Psyche spacecraft http://satswiss.com/solar-electric-propulsion-launches-nasas-psyche-spacecraft/ Mon, 20 Sep 2021 15:36:22 +0000 http://satswiss.com/solar-electric-propulsion-launches-nasas-psyche-spacecraft/

A gentle maneuver

Psyche will be launched from the historic Pad 39A at NASA’s Kennedy Space Center. The Falcon Heavy will put the spacecraft on a path to fly through Mars for gravitational assistance seven months later, in May 2023. In early 2026, the thrusters will do the delicate work of putting the spacecraft into orbit around the asteroid. Psyche, using a little ballet to get back into orbit around his target.

This task will be particularly tricky due to the scant knowledge scientists have about the asteroid, which only appears as a tiny dot of light in telescopes. Ground-based radar suggests it’s about 226 kilometers wide and shaped like a potato, meaning scientists won’t know until they get there how exactly its works. gravity field. As the mission conducts its 21-month scientific investigation, the navigation engineers will use the electrically powered thrusters to fly the spacecraft through a progression of orbiting that will gradually bring the spacecraft closer to Psyche.

NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission, used a similar propulsion system with the agency’s Deep Space 1, which was launched in 1998 and flew over an asteroid and a comet before the mission ended in 2001. Next came Dawn, who used solar electric propulsion to orbit the asteroid Vesta and then the protoplanet Ceres. The first spacecraft to orbit two alien targets, the Dawn mission lasted for 11 years, ending in 2018 when it used the last hydrazine thruster used to maintain its focus.

Propulsion Partners

Maxar Technologies has used solar electric propulsion to power commercial communications satellites for decades. But for Psyche, they needed to adapt the super efficient Hall thrusters to fly into deep space, and that’s where the engineers at JPL came in. Both teams hope Psyche, using Hall thrusters for the first time beyond lunar orbit, will help push the limits of solar electric propulsion.

“Solar electric propulsion technology offers the right combination of cost savings, efficiency and power and could play an important role in supporting future scientific missions to Mars and beyond,” said Steven Scott, Manager of the Psyche de Maxar program.

In addition to supplying the thrusters, the Maxar team in Palo Alto, Calif., Was responsible for building the spaceship’s van-sized chassis, which houses the electrical system, the propulsion systems, the system. thermal and the guidance and navigation system. When fully assembled, Psyche will move into JPL’s huge thermal vacuum chamber for tests simulating the deep space environment. By next spring, the spacecraft will be shipped from JPL to Cape Canaveral for launch.

Tianzhou-3 cargo spacecraft docks with Chinese space station module http://satswiss.com/tianzhou-3-cargo-spacecraft-docks-with-chinese-space-station-module/ Mon, 20 Sep 2021 14:52:00 +0000 http://satswiss.com/tianzhou-3-cargo-spacecraft-docks-with-chinese-space-station-module/

BEIJING, Sept.20 (Reuters) – A Chinese robotic refueling cargo spacecraft successfully docked with an orbiting space station module on Monday as part of the fourth of 11 missions needed to complete construction of the first space station permanent from China by the end of next year.

A Long March-7 rocket carrying the Tianzhou-3, or “Celestial ship” in Chinese, lifted off at 3:10 p.m. Beijing time (07:10 GMT) from the Wenchang Space Launch Center on the southern island of Hainan, reported the official media.

It successfully docked with the Tianhe central module of the space station at 1408 GMT.

Tianzhou-3 will provide fuel and supplies for three astronauts due to travel to the Tianhe module in October. Their planned six-month stay would be the fifth mission in the series and the last of this year.

Next year, China will launch two additional base modules for the space station – Wentian and Mengtian – on Long March 5B rockets – China’s most powerful space transport vehicles.

China began building the three-module space station in April with the deployment of Tianhe, followed by a three-month crewed mission that ended last week.

The station, when completed, will compete with the International Space Station (ISS), which is supported by countries like the United States, Russia and Japan. The United States has banned China from participating in the ISS.

Tianzhou-3 spacecraft docks with Chinese space station http://satswiss.com/tianzhou-3-spacecraft-docks-with-chinese-space-station/ Mon, 20 Sep 2021 14:22:55 +0000 http://satswiss.com/tianzhou-3-spacecraft-docks-with-chinese-space-station/

HELSINKI – China’s Tianzhou-3 cargo spacecraft docked in orbit with the Tianhe space station module on Monday after launching from the Wenchang coastal launch center.

A Long March 7 rocket took off from Wenchang at 3:10 a.m. (east) on September 20. Tianzhou-3 separated from the second stage after 597 seconds, having entered orbit and on track to catch up with Tianhe.

Deng Hongqin, director of the Xichang Satellite Launch Center, which administers Wenchang, said the launch was a complete success during the live coverage.

The unmanned Tianzhou-3 spacecraft completed automated quick rendezvous and docking maneuvers with Tianhe just under seven hours later at 10:08 p.m. EST, CCTV reported. The spacecraft used six orbital maneuvers after reaching orbit to approach Tianhe.

Tianzhou-3 is carrying around six tons of supplies for the upcoming Shenzhou-13 crewed mission as construction of the Chinese space station continues. The cargo consists mostly of fresh supplies for astronauts for what will be China’s longest manned space flight mission to date. Other payloads include experiments and equipment.

The six-month Shenzhou-13 mission will be launched from Jiuquan to the Gobi Desert in early October. The spacecraft and its Long March 2F rocket were in readiness in Jiuquan for a while to allow for a possible rapid response to an orbit emergency.

The crew is rumored to include one of two Chinese female astronauts. Wang Yaping, a 2013 Shenzhou-10 mission veteran, is in training for space station missions.

The Tianzhou-3 mission is the fourth for the construction of the Chinese space station. Tianhe, the station’s first 22.5-tonne module, launched end of April 28 and is currently in an orbit of 386 by 380 kilometers inclined at 41.5 degrees.

The first crewed mission, Shenzhou-12, returned to earth September 17th after 90 days of mooring in Tianhe. Following this, the Tianzhou-2 spacecraft, which provided supplies and equipment to the crew, undocked from Tianhe’s rear port on Saturday and carried out circumnavigation and forward mooring maneuvers, giving way to Tianzhou-3.

Tianzhou-2 and Tianzhou-3 will remain moored with Tianhe (“harmony of the heavens”) 16.6 meters long and 4.2 meters in diameter until the arrival of Shenzhou-13.

This requires the Shenzhou spacecraft to complete a radial rendezvous, or R-Bar, and dock with the nadir docking port of Tianhe. In preparation for this leg, Shenzhou-12 tested the relatively more difficult radial rendezvous without docking before returning to Earth. The spacecraft approached and stopped at distances of 200 and 19 meters.

Tianzhou-2 will be used for a verification test of the space station’s main robotic arm before it de-orbits. The arm will test its ability to manipulate modules on the side rings of the Tianhe docking hub.

China has scheduled 11 missions to complete China’s three-module, 66-metric-ton Tiangong space station by the end of 2022. Tianzhou-3 and Shenzhou-13 will be the last two in the technology verification phase.

Key technology verification includes test systems such as regenerative life support, radial rendezvous, robotic arm, solar power systems, thruster transfer to forward and aft docking ports, and perform extravehicular activities.

According to unofficial projections, Shenzhou-13 will run from October to March 2022. The Tianzhou-4 supply mission would then follow about a month later, with Shenzhou-14 taking flight in May 2022. This crewed mission will oversee the main developments in the construction of space. station.

The two experimentation modules, Wentian and Mengtian, are to be launched in May-June and August-September respectively. Finally, Tianzhou-5 would be launched in October in anticipation of Shenzhou-15 in November 2022, completing the construction phase.

China has hinted at plans to expand the Tiangong complex to six modules. The extension would use backup modules or potentially include an international contribution.

Beijing: China successfully launched a Tianzhou-3 unmanned cargo spacecraft on Monday to deliver supplies to its under-construction Tiangong space station, which is expected to be completed by next year.

The Long March-7 Y4 rocket, carrying Tianzhou-3, took off from the Wenchang spacecraft launch site in the southern island province of Hainan, the Chinese Space Agency (CMSA) said.

Tianzhou-3 will later dock with the combination of the Tianhe space station core module and the Tianzhou-2 cargo ship, CMSA said.

The Tianzhou series is a cargo vessel carrying material supplies to the space station which is due to be ready by next year.

On September 18, the cargo ship Tianzhou-2 separated from the aft docking port of Tianhe and docked at its forward docking port.

CMSA said the Tianhe and Tianzhou-2 suit is in good condition, awaiting docking with the Tianzhou-3 freighter and the upcoming Shenzhou-13 manned spacecraft, the state-run Xinhua news agency reported.

On September 17, three Chinese astronauts who spent 90 days, the country’s longest crewed mission, returned to Earth. The three spent three months building the station.

They spent 90 days in the Tianhe module of the Chinese space station, some 380 kilometers above Earth.

Hailed as the most prestigious and strategically important space project for China after the country’s recent missions to Mars and the Moon, the low-orbiting space station is said to be the eye of the country from the sky, providing an in-flight view. from bird 24 hours a day to its astronauts to the rest of the world.

China has already sent the main cabin module for the Tianhe space station on April 29 and a cargo spacecraft with supplies on May 29. Once ready, China will be the only country to own a space station while the aging International Space Station (ISS) is now a collaborative project of several countries.

It is expected to compete with the ISS and perhaps become the only space station to remain in orbit after the ISS is removed.

The Chinese space station is also equipped with a robotic arm on which the United States has expressed concerns about its possible military applications.

The arm, which can be stretched up to 15 meters, will also play a vital role in building the orbiting space station, said Zhou Jianping, chief designer of China’s Manned Space Engineering Project. Astronauts will team up with the robotic arm to make the construction and maintenance of the space station in orbit possible.

In the past, China has launched several scavenging satellites equipped with robotic arms to collect and direct space debris to burn in Earth’s atmosphere. Once ready, the station should be open to close allies of China such as Pakistan and other international space cooperation partners.

Ji Qiming, assistant director of CMSA, told media on Wednesday that in addition to close cooperation with Russia, China also maintains bilateral cooperation exchanges with countries such as France, Italy, Pakistan and others, focused on space experiments in basic physics, space medicine and space station autonomy.

Separately, China and Russia also unveiled a roadmap to build a lunar space station, state media reported. The station aims to develop research facilities on the surface of the Moon, in orbit, or both.

China plans to send several space missions, including with astronauts to transport supplies and equipment to complete construction of the space station.

The space station will operate in low Earth orbit at an altitude of 340-450 km above the Earth’s surface for more than 10 years.

The T-shaped station has a central module in the center and a lab capsule on each side.
Each of the modules will weigh more than 20 tonnes, with the total mass of the station expected to weigh around 66 tonnes.

Chinese President Xi Jinping, who spoke to the three astronauts shortly after entering the space station in June, called the project “a milestone” in the country’s ambitious space exploration program.

“The construction of the space station is a milestone in China’s space industry, which will make pioneering contributions to the peaceful use of space by mankind,” Xi said.

China will conduct two more space launches for the construction of the space station this year – the Tianzhou-3 cargo spacecraft via a Long March-7 carrier rocket from Wenchang spaceport in Hainan and another manned flight on a Shenzhou spacecraft. -13 via a Mars-2F Long Rocket from downtown Jiuquan, the Global Times newspaper reported.

After the Tianzhou-3 mission, the Shenzhou-13 manned spacecraft is expected to send another crew of three taikonauts to the Chinese space station complex. They will live and work in orbit for an even longer stay of six months, he said.
