Europe Will Witness the Historic Ariane 6 First Launch

Published

on

Europe is about to witness a historic event as the Ariane 6 launch rocket gets ready for its first flight on Tuesday.

On July 9, between 2:00 and 6:00 p.m. Eastern (1800 and 2200 UTC), the Ariane 6 is scheduled to lift off from the Kourou launch pad in French Guiana. The launch is being broadcast live on ESAWebTV by the European Space Agency (ESA).

With two solid boosters, the 56-meter-long “62” version of Ariane 6 will be used on its first launch. The Vulcain 2.1 engine, which runs on liquid hydrogen and oxygen, powers the main stage. This is an improvement over the primary Vulcain engine of the Ariane 5.

The larger “64,” which has four solid rockets, can lift up to 21.6 tons, whereas the 62 can only take up to 10.3 tons to low Earth orbit. However, just a few small satellites and experiments from businesses, research centers, universities, and young people will be carried on the inaugural trip.

Years of delays are followed by the first rollout. The launcher is intended to replace the aging and now-retired Ariane 5 with a less expensive model. Originally, 2020 was supposed to be the rocket’s first flight date.

The maiden launch of Ariane 6 will be a crucial and high-pressure operation for launch service provider Arianespace, European Space Agency (ESA), prime contractor ArianeGroup, and other stakeholders due to the launcher’s delays, a backlog of thirty orders, and the crises surrounding European access to space.

The European Space Policy Institute’s director, Hermann Ludwig Moeller, told SpaceNews that “For Europe it is mission critical to again have an autonomous access to space,”

By doing this, the beginning of its own institutional missions would be ensured. According to Moeller, these comprise the EU Space Programme, EUMETSAT meteorological satellites, ESA missions, security and defense-related operations, and operator-related commercial programs.

Thirteen launches for Ariane 6 are already scheduled, eighteen of which are for Amazon’s Kuiper constellation.

There is a sense of danger since, contingent upon a successful flight, Ariane will shortly increase from six to nine trips annually.

On the other hand, test launches frequently fail. Reducing expectations, ESA director general Josef Aschbacher stated in May that  “Statistically, there’s a 47% chance the first flight may not succeed or happen exactly as planned,”

Furthermore, according to Moeller, “space applications such as improved weather forecasting, banking and timing services, secure communications, 5G and Internet, civil and economic security, including protection of critical infrastructures in transport, energy, digital, and defense applications” will benefit from the operational launcher.

“Ariane 6 is essential and a prerequisite for the implementation of a broader European space policy and strategy.”

Moeller responded, “The main impact in our view is the fact that the focus on the launcher crisis has made it difficult to advance on other dossiers and in particular on the accelerated use of space, at a time when other space powers and commercial entreprise do exactly that, in a race.”  when asked how the expendable Ariane 6 and its extensive delays have potentially cost the European space sector.

“And it is not the Falcon 9 launcher that is most visible in the debate, but the Starlink communications constellation, known to every taxi driver. It is not too late for Europe to catch-up, and IRIS2 is one step in that direction. However, the window of opportunity is now and it will close.”

Due to the unanticipated pause between Ariane 5’s retirement and Ariane 6’s launch, ESA had to launch the EarthCARE satellite in May of last year and its Euclid space telescope on a Falcon 9.

Notably, in late June, European weather satellite operator Eumetsat revealed that one of its geostationary weather satellites had been transferred from an Ariane 6 to a Falcon 9. European space authorities were taken aback by the decision, which Eumetsat claims was made for complicated but unclear reasons.

Europe is also seeking to diversify its launch services, in part as a reaction to its access to space dilemma. The commercialization of the ESA-developed Vega by prime contractor Avio was made possible by a resolution passed by the ESA Council on July 5.

Four micro- and mini-launchers from European launch service companies, Isar Aerospace, MaiaSpace, PLD Space, and Rocket Factory Augsburg (RFA), were also granted permission by the Council to utilize the French Guiana spaceport.

According to an ESA statement, “These decisions set the stage for more diverse European launch services in an increasingly competitive environment.”

The company’s stance is that the EU and ESA should acquire the service, and the private sector should develop rockets in the future. According to RFA, “Post Ariane 6 launch service development and operation shall be led by private industry,” Meanwhile, the company expressed excitement for the launch of Ariane 6 and called it “a great pan-European project.”

Moeller pointed out that Europe must look past the initial release. “By July 10, the focus in Europe needs to shift beyond launchers to the accelerated use of space, in all domains and to the benefit of the entire European economy, for the prosperity of its citizens, the competitiveness of its industries, as well as for the protection of global peace and inspiration of future generations.”

A NASA spacecraft ‘touches the sun’ during a turning point in human history

Published

on

On Christmas Eve, NASA’s Parker Solar Probe set a new record by approaching the sun’s surface within barely 3.86 million miles (6.1 million kilometers). Parker’s historic moment can be followed on NASA’s Eyes On The Solar System page.

On Tuesday, December 24, a fully armored NASA spacecraft, barely larger than a tiny car, became the closest man-made object to the sun in history, marking one of humanity’s most amazing space exploration achievements. In addition, the fastest item ever created by humans broke its speed record, and humanity made its closest visit to a star ever.

A Monumental Performance

At 11:53 UTC (6:53 a.m. EST) on Tuesday, December 24, Parker accomplished an unprecedented close flyby of the sun, coming within barely 3.86 million miles (6.1 million kilometers) of its surface. This was a tremendous accomplishment of exploration. It had come this near to the sun 22 times.

It is the closest man-made object to the sun ever, at 96% of the distance between the sun and Earth, well within Mercury’s orbit at roughly 39%.

The project’s scientist at the Johns Hopkins Applied Physics Laboratory, Dr. Nour Raouafi, compares the importance of this mission to the 1969 moon landing. During a media roundtable at the annual conference of the American Geophysical Union on December 10, 2024, he declared, “It’s the moment we have been waiting for for nearly 60 years.” “In 1969, we landed humans on the moon. On Christmas Eve, we embrace a star — our star.”

‘Hyper-Close’

Parker will slice through plasma plumes that are still attached to the sun in what NASA refers to as a “hyper-close regime,” getting close enough to pass inside a solar outburst “like a surfer diving under a crashing ocean wave.”

According to Raouafi, the heat Parker will experience when it is closest to the sun is “nearly 500 times the hottest summer day we can witness on Earth.”

Parker was already the fastest thing ever constructed on Earth, but it will surpass all previous records for speed and distance when it approaches the sun at 430,000 mph (690,000 kph). The mission’s website states that it would take one second to go from Philadelphia to Washington, D.C.

On December 27, 2024, mission operators at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, will wait for a beacon tone to certify the probe’s survival after losing touch with it for three days.

On March 22 and June 19, 2025, Parker will make two additional hyper-close passes at the same distance.

Researchers Achieve Breakthrough in Quantum Simulation of Electron Transfer

Published

on

A team at Rice University has achieved a significant breakthrough in simulating molecular electron transfer using a trapped-ion quantum simulator. Their research offers fresh insights into the dynamics of electron transfer and could pave the way for innovations in molecular electronics, renewable energy, and cc.

Electron transfer is a critical process underpinning numerous physical, chemical, and biological phenomena. However, the complexity of quantum interactions has long made it a challenging area to study. Conventional computational techniques often struggle to capture the full range of variables influencing electron transfer.

To address these challenges, the researchers developed a programmable quantum system capable of independently controlling key factors such as donor-acceptor energy gaps, electronic and vibronic couplings, and environmental dissipation. Using ions trapped in an ultra-high vacuum and manipulated by laser light, the team demonstrated real-time spin dynamics and measured electron transfer rates.

“This is the first time that this kind of model has been simulated on a physical device while incorporating the role of the environment and tailoring it in a controlled way,” said Guido Pagano, lead author of the study published in Science Advances.

Pagano added, “It represents a significant leap forward in our ability to use quantum simulators to investigate models and regimes relevant to chemistry and biology. By harnessing the power of quantum simulation, we hope to explore scenarios currently inaccessible to classical computational methods.”

Through precise engineering of tunable dissipation and programmable quantum systems, the researchers explored both adiabatic and nonadiabatic regimes of electron transfer. The experiment not only illuminated how quantum effects function under diverse conditions but also identified optimal parameters for electron transfer.

The team emphasized that their findings bridge a critical gap between theoretical predictions and experimental verification. By offering a tunable framework to investigate quantum processes in complex systems, their work could lead to groundbreaking advancements in renewable energy technologies, molecular electronics, and the development of novel materials.

“This experiment is a promising first step toward understanding how quantum effects influence energy transport, particularly in biological systems like photosynthetic complexes,” said Jose N. Onuchic, study co-author. “The insights gained could inspire the design of more efficient light-harvesting materials.”

Crew Dragon Mission Delay Extends Astronauts’ Stay on ISS by a Month

Published

on

The next mission of SpaceX’s Crew Dragon to the International Space Station (ISS) has been postponed by a month due to delays in completing a new spacecraft. This decision will extend the stay of some astronauts aboard the ISS, including two who have been there since June.

NASA announced on December 17 that the Crew-10 mission, initially scheduled for February, is now set to launch no earlier than late March. The delay stems from the need for additional time to finish the fabrication, assembly, testing, and integration of a new Crew Dragon capsule.

Crafting the New Dragon Capsule

“Fabrication, assembly, testing, and final integration of a new spacecraft is a painstaking endeavor that requires great attention to detail,” said Steve Stich, NASA’s Commercial Crew Program Manager. He commended SpaceX’s efforts to expand the Dragon fleet and the flexibility of the ISS crew in accommodating the delay.

The new Crew Dragon will be the fifth in SpaceX’s lineup of crewed spacecraft, complementing its three cargo Dragon vehicles. According to Sarah Walker, SpaceX’s Dragon Mission Management Director, the spacecraft was near completion as of July and was undergoing final work at SpaceX’s California facility. It is now expected to arrive in Florida for final preparations in January.

While NASA did not specify the exact reasons for the delay, it considered other options, including using an existing Crew Dragon or making adjustments to the launch manifest, before opting for the delay. Existing capsules, including Freedom, currently at the ISS, and Endeavour and Resilience, which recently returned from other missions, were not available for a February launch.

Crew Adjustments and Extended ISS Stay

The Crew-10 mission will proceed with its planned roster: Anne McClain and Nichole Ayers from NASA, Takuya Onishi from JAXA, and Kirill Peskov from Roscosmos.

The delay has implications for the Crew-9 mission, launched in late September with NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov. They were joined by NASA astronauts Suni Williams and Butch Wilmore, who have been on the station since June after arriving on Boeing’s CST-100 Starliner.

Originally, Williams and Wilmore were scheduled to stay for just over a week, but their time on the ISS will now extend to about 10 months. NASA had earlier decided to return the uncrewed Starliner to Earth due to concerns with its thrusters.

Despite the delay, NASA emphasizes that Williams and Wilmore are not “stranded” as they can return to Earth in an emergency. Their extended stay is tied to the decision to use the new Crew Dragon for the upcoming mission, as preparing another vehicle was deemed impractical.

Looking Ahead

Assuming the Crew-10 launch proceeds in late March, the Crew-9 spacecraft is expected to return to Earth in early April after a handover period. This delay underscores the complexity of preparing new spacecraft while ensuring the safety and readiness of all missions.

As the new Crew Dragon nears completion, SpaceX and NASA remain focused on maintaining seamless operations aboard the ISS and advancing human space exploration.
