Ariane 6: Europe’s New Rocket | European Space Agency

Ariane 6: Europe’s New Rocket | European Space Agency

 

European Space Agency: "Ariane 6 is the newest rocket in a series that has, for five decades, been launching Europe towards the stars. Building on all the knowledge, expertise and technology developed over the years, Ariane 6 will be versatile, modular, and European."

"Guaranteeing Europe’s access to space for the next years, Ariane 6 in two versions, with either two or four boosters attached depending on the ‘oomph’ the mission requires. Versatile, its upper stage can reignite multiple times during a single flight, placing any spacecraft into any orbit—including constellations—saving a final boost to return and burn up in Earth’s atmosphere. Modular, it will be continuously adapted to the needs of the future space sector."

"Four organizations take care of the Ariane 6 program: The European Space Agency (ESA) at the head, ArianeGroup as the main contractor, CNES who designed and built the launchpad and ArianeSpace who sell the launches."

"Thirteen countries contribute, thousands of Europeans have worked on it, and every one of us will benefit from the Earth observation, science, technologies and services it will make possible."

The Trifid Nebula in Sagittarius

The Trifid Nebula in Sagittarius

The beautiful Trifid Nebula is a cosmic study in contrasts. Also known as M20, it lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid does illustrate three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection nebulae produced by dust reflecting starlight, and dark nebulae where dense dust clouds appear in silhouette. 

However, the red emission region, roughly separated into three parts by obscuring dust lanes, is what lends the Trifid its popular name. Pillars and jets sculpted by newborn stars, above and right of the emission nebula's center, appear in famous Hubble Space Telescope close-up images of the region. The Trifid Nebula is about 40 light-years across. Too faint to be seen by the unaided eye, it almost covers the area of a full Moon on planet Earth's sky.

Shenzhou-18 Astronauts Complete Second Spacewalk | China Space Station

Shenzhou-18 Astronauts Complete Second Spacewalk | China Space Station


The Shenzhou-18 astronauts aboard China's orbiting space station completed their second spacewalk at 22:51 (Beijing Time) on Wednesday, July 4, 2024 according to the China Manned Space Agency (CMSA).

Ye Guangfu, Li Cong, and Li Guangsu worked for about 6.5 hours to accomplish multiple tasks with Li Guangsu remaining inside the space station.

With the assistance of the space station's robotic arm and researchers on Earth, they installed space debris protection devices for the pipelines, as well as cables and key equipment outside the Tiangong space station, and conducted an extravehicular inspection.

At 16:19, Li Cong opened the hatch door of the Wentian space lab module and began his first spacewalk.

With the assistance of the space station's robotic arm, Li came to the operation point. Then Ye Guangfu transferred the relevant equipment and devices out of the space station and exited the capsule at 17:41.

Ye climbed to the operation point by himself, and cooperated with Li to install protection devices for the cables of the Wentian lab module and the pipelines of the Tianhe core module.

In the meantime, Li Guangsu carried out monitoring of the robotic arm and provided necessary support from inside the Tianhe core module.

"The main purpose of the spacewalk this time is to install protection devices for extravehicular equipment, mainly cables and pipelines, so as to improve the space station's ability to operate safely and steadily over the long term," said Liu Ming, an engineer with the China Aerospace Science and Technology Corporation (CASC).

After installing protection devices, Li Cong mounted the robotic arm and conducted an extravehicular inspection of the space station's facilities through his helmet camera.

After completing the predetermined tasks, Ye Guangfu and Li Cong returned safely to the Wentian lab module.

"The Chinese space station is very beautiful. Whenever the robotic arm moves to the highest point, I can't help taking more glances at the space station despite the glaring sunlight. I really feel the greatness of the project from my heart, and I applaud all the space professionals and our motherland. We will make continuous efforts to successfully and efficiently complete the follow-up tasks to the end. Let's meet again inside the cabin," Li Cong said outside the space station.

In their previous spacewalk on May 28, the Shenzhou-18 trio mainly installed protection devices for the extravehicular cables of the Mengtian lab module.

The Shenzhou-18 crew, sent to the space on April 25 this year, have completed one third of their space journey and are scheduled to carry out a large amount of in-orbit scientific experiments and technological tests, the agency said.

Starship's Fourth Flight Test | SpaceX

Starship's Fourth Flight Test | SpaceX

"Starship is essential to both SpaceX’s plans to deploy its next-generation Starship system as well as for NASA, which will use a lunar lander version of Starship for landing astronauts on the Moon during the Artemis III mission through the Human Landing System (HLS) program."

Fourth SpaceX Starship Flight on June 6, 2024

SpaceX statement on the results: 

On June 6, 2024, Starship successfully lifted off at 7:50 a.m. CT from Starbase in Texas and went on to deliver maximum excitement: The Super Heavy booster lifted off successfully and completed a full-duration ascent burn.

Starship executed another successful hot-stage separation, powering down all but three of Super Heavy’s Raptor engines and successfully igniting the six second stage Raptor engines before separating the vehicles.

Following separation, the Super Heavy booster successfully completed its flip maneuver, boostback burn to send it towards the splashdown zone, and jettison of the hot-stage adapter.

The booster’s flight ended with a landing burn and soft splashdown in the Gulf of Mexico seven minutes and 24 seconds into the flight.

Starship's six second stage Raptor engines successfully powered the vehicle to space and placed it on the planned trajectory for coast.

Starship made a controlled reentry, successfully making it through the phases of peak heating and max aerodynamic pressure and demonstrating the ability to control the vehicle using its flaps while descending through the atmosphere at hypersonic speeds.

Starlink on Starship once again enabled real-time telemetry and live high-definition video throughout every phase of entry, with external cameras providing views all the way to the flight’s conclusion.

Flight 4 ended with Starship igniting its three center Raptor engines and executing the first flip maneuver and landing burn since our suborbital campaign, followed by a soft splashdown of the ship in the Indian Ocean one hour and six minutes after launch.

The fourth flight of Starship made major strides to bring us closer to a rapidly reusable future. Its accomplishments will provide data to drive improvements as we continue rapidly developing Starship into a fully reusable transportation system designed to carry crew and cargo to Earth orbit, the Moon, Mars and beyond.

Congratulations to the entire SpaceX team on an inspired fourth flight test of Starship! And thank you to our customers, Cameron County, spaceflight fans, and the wider community for the continued support and encouragement.

Binary Star Eta Carinae—A Source of Very High-energy Cosmic Gamma Radiation

Binary Star Eta CarinaeA Source of Very High-energy Cosmic Gamma Radiation

The binary star Eta Carinae may be about to explode. However, no one knows when. It may be next year. It may be a million years from now. Eta Carinae's mass—about 100 times greater than our Sun—makes it an excellent candidate for a full blown supernova. Historical records do show that about 170 years ago Eta Carinae underwent an unusual outburst that made it one of the brightest stars in the southern sky. This binary star in the Homunculus Nebula is located 7,500 light-years away in the constellation Carina. Eta Carinae is the only star system currently thought to emit natural LASER light. 

With the gamma-ray telescopes of the High Energy Stereoscopic System (H.E.S.S.), astrophysicists have detected very high energy gamma rays from Eta Carinae. It constitutes a new type of source for such high-energy radiation. The DESY animation by Science Communication Lab takes you on an interstellar roadtrip to this extraordinary system.

Global Atmospheric Methane (CH₄) | NASA Earth Observatory

Global Atmospheric Methane (CH₄) | NASA Earth Observatory

Methane (CH₄) is a powerful greenhouse gas that traps heat 28 times more effectively than carbon dioxide over a 100-year timescale. Concentrations of methane have increased by more than 150% since industrial activities and intensive agriculture began. After carbon dioxide, methane is responsible for about 20% of climate change in the twentieth century. Methane is produced under conditions where little to no oxygen is available. 

About 30% of methane emissions are produced by wetlands, including ponds, lakes and rivers. Another 20% is produced by agriculture, due to a combination of livestock, waste management and rice cultivation. Activities related to oil, gas, and coal extraction release an additional 30%. The remainder of methane emissions come from minor sources such as wildfires, biomass burning, permafrost, termites, dams, and the ocean. 

Scientists around the world are working to better understand the budget of methane with the ultimate goals of reducing greenhouse gas emissions and improving prediction of environmental change. 

The NASA SVS visualization presented here shows the complex patterns of methane emissions produced around the globe and throughout the year from the different sources described above. The visualization was created using output from the Global Modeling and Assimilation Office (GMAO), GEOS modeling system, developed and maintained by scientists at NASA. Wetland emissions were estimated by the LPJ-wsl model, which simulates the temperature and moisture dependent methane emission processes using a variety of satellite data to determine what parts of the globe are covered by wetlands. Other methane emission sources come from inventories of human activity.

Shenzhou-18 Crew Continues Experiments for 2nd Month | China Space Station

Shenzhou-18 Crew Continues Experiments for 2nd Month | China Space Station

The crew of the Shenzhou-18 mission has been continuously conducting experiments aboard China's Tiangong space station for the second month. The three Chinese astronauts, Ye Guangfu, Li Cong and Li Guangsu, were sent to the orbiting Tiangong space station for a six-month mission on April 25, 2024. 

The crew regularly maintained the combustion science laboratory cabinet by replacing burners, vacuuming and exhausting, and organizing related materials to better carry out the following experimental projects. 

The combustion science laboratory cabinet has been used in experiments since the in-orbit ignition experiment in 2023. The facility is expected to contribute to scientific achievements in improving the fundamental theory of combustion and developing advanced combustion technology.

The crew recently installed slide positioning kits for the glovebox. The glovebox provides a sealed and clean space for crew members to manipulate objects in experiments.

The astronauts have also regularly replaced experimental samples, cleaned the chamber and maintained the axial mechanism electrodes for the containerless materials laboratory cabinet to ensure the stable and smooth operation of relevant experiments.

In addition, the crew also replaced samples in the fluid physics laboratory cabinet. The cabinet is used to conduct on-orbit microgravity experiments on the kinetic processes, diffusion processes, phase transitions and self-organization behavior of different fluid systems.

Stellar Nursery L1527 & Protostar in Taurus | James Webb Space Telescope

Stellar Nursery L1527 & Protostar in Taurus | James Webb Space Telescope

L1527, shown in this image from NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument), is a molecular cloud that harbors a protostar. The protostar is a relatively young object of about 100,000 years. It resides about 460 light-years from Earth in the constellation Taurus. The more diffuse blue light and the filamentary structures in the image come from organic compounds known as polycyclic aromatic hydrocarbons (PAHs), while the red at the center of this image is an energized, thick layer of gases and dust that surrounds the protostar. The region in between, appearing in white, is a mixture of PAHs, ionized gas, and other molecules.

The effects of stellar outflows are visible. They are emitted in opposite directions along the protostar’s rotational axis as the object consumes gas and dust from the surrounding cloud. These outflows take the form of bow shocks to the surrounding molecular cloud. They appear as filamentary structures throughout. They are also responsible for carving the bright hourglass structure within the molecular cloud as they energize, or excite, the surrounding matter and cause the regions above and below it to glow. This creates an effect reminiscent of fireworks brightening a cloudy night sky. 

As the protostar continues to age and release energetic jets, it will consume, destroy, and push away much of this molecular cloud, and many of the structures we see here will begin to fade. Eventually, once it finishes gathering mass, this impressive display will end, and the star itself will become more apparent, even to visible-light telescopes.
