Virgin Galactic to lose funding from its billionaire founder | Digital Trends

Richard Branson has said he will no longer put any money into Virgin Galactic, the space tourism company that he founded in 2004.

The surprise decision, first reported by the Financial Times, caused the company’s share value to drop sharply on Monday.

Branson told the Times: “We don’t have the deepest pockets after Covid, and Virgin Galactic has got $1 billion, or nearly.”

He added that as things stand, Virgin Galactic should have “sufficient funds to do its job on its own.”

Virgin Galactic flew its first commercial passengers to the edge of space in June and has gone on to fly a further four additional commercial flights. The most recent one took place at the start of last month, but just a few days later the company announced it was reducing its workforce and suspending commercial flights for 18 months from next year in an effort to save money while it develops a larger aircraft capable of carrying more passengers to space than the current vehicle, which can transport up to six paying passengers at a time.

Before the suspension, Virgin Galactic plans to fly its sixth commercial mission in January, followed by a seventh in the second quarter, and possibly an eighth in the middle of 2024. Virgin Galactic CEO Michael Colglazier said that for the remaining flights, Virgin Galactic will focus on higher revenue opportunities. It means that private passengers could be asked to pay a premium rate of up to $1 million, more than double that of the current seat price of $450,000.

The new, larger vehicle, called Delta, should be ready in 2026, and Virgin Galactic says it has adequate funds to continue operating until then. At that point, the plan is for Delta to begin commercial flights, attracting new revenue in the process.

However, the FT’s report says that some analysts believe Virgin Galactic will need to look for additional funding from investors possibly in 2025, a year before Delta is ready.

The Virgin Galactic flight experience involves a rocket-powered flight close to the Kármán line, an area about 62 miles above Earth that’s generally regarded as where space begins. Passengers can enjoy stunning views of Earth and a view minutes weightlessness inside the cabin before gliding back for a runway landing.

NASA’s Mars helicopter back in the air after a long break | Digital Trends

NASA’s Mars helicopter, Ingenuity, has taken to the skies again following a month-long break in communications with Earth.

The drone-like flying machine flew for 393 meters and stayed in the air for more than two minutes. Showing no signs of trouble following its extended period on the ground, the helicopter also reached an altitude of 39 feet (11.9 meters) and hit a top speed of 11.9 mph (5,4 meters per second).

NASA’s Jet Propulsion Laboratory, which operates Ingenuity, revealed news of the aircraft’s 67th flight in a post on social media:

The suspension of flights was due to a break in communications between the Ingenuity team and the helicopter, caused by the sun coming between Earth and Mars.

The so-called “solar conjunction” happens every couple of years, and so this is the second time for it to affect NASA’s latest Mars mission, which also includes the Perseverance rover. NASA’s other Mars vehicles — the Curiosity rover and three Mars orbiters — have been operation on and near to the planet for much longer and so have experienced multiple solar conjunctions.

Ingenuity has performed way beyond initial expectations since becoming the first aircraft to perform powered, controlled flight on a planet other than Earth in April 2021.

In fact, it’s impressed NASA so much that it wants to design more advanced aircraft for future missions on Mars and other planets.

Ingenuity arrived on Mars as a technology demonstration, but after proving itself, the JPL team deployed it for gathering aerial imagery of the martian surface using the aircraft’s on-board camera. This imagery has been used to help map safe and efficient routes for the ground-based Perseverance rover, an advantage not available to earlier Mars missions such as Curiosity, Spirit, and Opportunity.

Perseverance continues to explore the martian surface for evidence of ancient microbial life, with scientists aiming to send some of the rover’s collections of rock and soil to Earth for closer analysis.

Animation depicts first launch of Europe’s next-gen rocket | Digital Trends

The Ariane 5 rocket flew its last mission in June, leaving Europe without a heavy-lift vehicle to carry spacecraft to orbit.

Its operator, Arianespace, is working on the rocket’s successor, the Ariane 6, and revealed last week that it will take its maiden test flight no earlier than June 15, 2024.

On Sunday, the France-based aerospace company shared an animation (below) showing what a typical launch will look like, including the various phases of flight as the vehicle heads to orbit.

Ariane 6 launch animation

Arianespace is building two versions of the Ariane 6. Ariane 62 will fly with two strap-on boosters while the more powerful Ariane 64 will fly with four.

“At over 60 meters tall, Ariane 6 will weigh almost 900 tons when launched with a full payload — roughly equivalent to one and a half Airbus A380 passenger aircraft,” Arianespace said in comments accompanying the video.

The rocket’s upper stage engine, called Vinci, is fed by liquid hydrogen and oxygen and can be stopped and restarted multiple times, making it ideal for missions in which multiple satellites need to be placed in different orbits.

This will be particularly useful in so-called “rideshare” missions that will allow multiple companies to join a single flight, thereby offering customers a more cost-effective way to deploy small satellites in space.

Following satellite deployment, the Ariane 6’s upper stage will deorbit and burn up in Earth’s atmosphere, ensuring that it doesn’t become hazardous space junk that could otherwise threaten operational satellites in near-Earth orbit.

The development of the Ariane 6 is a mammoth project, involving several hundred companies in 13 European countries, led by prime contractor ArianeGroup.

France’s space agency, CNES, is currently working on the Ariane 6 launch facilities at Europe’s Spaceport in French Guiana, the same site from where the Ariane 5 departed in its final launch five months ago.

In development since 2014, the Ariane 6’s first flight was supposed to take place in 2020, but a number of delays pushed the date to next year.

James Webb captures dramatic image of newborn star | Digital Trends

A new image of a Herbig-Haro object captured by the James Webb Space Telescope shows the dramatic outflows from a young star. These luminous flares are created when stellar winds shoot off in opposite directions from newborn stars, as the jets of gas slam into nearby dust and gas at tremendous speed. These objects can be huge, up to several light-years across, and they glow brightly in the infrared wavelengths in which James Webb operates.

This image shows Herbig-Haro object HH 797, which is located close to the IC 348 star cluster, and is also nearby to another Herbig-Haro object that Webb captured recently: HH 211.

The NASA/European Space Agency/Canadian Space Agency’s James Webb Space Telescope reveals intricate details of Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. ESA/Webb, NASA & CSA, T. Ray (Dublin Institute for Advanced Studies)

The image was taken using Webb’s Near-Infrared Camera (NIRCam) instrument, which is particularly suited to investigating young stars, Webb scientists explain in a statement, : “Infrared imaging is a powerful way to study newborn stars and their outflows, because the youngest stars are invariably still embedded within the gas and dust from which they are formed. The infrared emission of the star’s outflows penetrates the obscuring gas and dust, making Herbig-Haro objects ideal for observation with Webb’s sensitive infrared instruments.

“Molecules excited by the turbulent conditions, including molecular hydrogen and carbon monoxide, emit infrared light that Webb can collect to visualize the structure of the outflows. NIRCam is particularly good at observing the hot (thousands of degree Celsius) molecules that are excited as a result of shocks.”

This particular Herbig-Haro object is unusual in that scientists originally believed that it was created from a single young star, as most such objects are. But these detailed observations reveal that there are actually two sets of outflows, coming from a pair of stars at the center.

In addition to the bright ripples of the Herbig-Haro object in the lower half of the image, there are also thought to be more new stars being born in the upper half of the image. The bright smudge in shades of yellow and green is believed to host two young protostars.

Mars Odyssey pulls a sideways maneuver to capture horizon | Digital Trends

A new image from a NASA orbiter shows an unusual view of Mars that captures the planet’s horizon complete with clouds. It is similar to the kinds of views of Earth that astronauts get from the International Space Station, showing what Mars would look like if seen from a similar vantage point.

The image was taken by NASA’s Mars Odyssey spacecraft, which has been orbiting the planet since 2001. In its over 20 years of operations, the orbiter made key discoveries, including some of the first detections of subsurface ice on the planet. It has also created a global map of the planet’s surface using its Thermal Emission Imaging System (THEMIS) instrument.

This unusual view of the horizon of Mars was captured by NASA’s Odyssey orbiter using its THEMIS camera via an operation that took engineers three months to plan. It’s taken from about 250 miles above the Martian surface – about the same altitude at which the International Space Station orbits Earth. NASA/JPL-Caltech/ASU

“If there were astronauts in orbit over Mars, this is the perspective they would have,” said Jonathon Hill of Arizona State University, operations lead for Odyssey’s THEMIS camera, in a statement. “No Mars spacecraft has ever had this kind of view before.”

The THEMIS instrument is the same one that was used to capture this image from around 250 miles above the planet’s surface. The spacecraft took a series of 10 images that show the planet’s horizon from beneath the cloud layer, which was a difficult feat that took months of planning to achieve. A big challenge for capturing this image was dealing with the THEMIS camera, which is attached to the spacecraft and points straight down toward the surface.

“I think of it as viewing a cross-section, a slice through the atmosphere,” said Jeffrey Plaut, Odyssey’s project scientist at NASA’s Jet Propulsion Laboratory. “There’s a lot of detail you can’t see from above, which is how THEMIS normally makes these measurements.”

To capture a better view of the atmosphere that included layers of clouds and dust, the entire spacecraft needed to roll over onto its side while still keeping its solar panels pointed toward the sun. In order to get into the right position, the spacecraft’s communication antenna had to be pointed away from Earth, so the team was out of communication with the craft throughout the maneuver.

The spacecraft spent an entire orbit rolled onto its side, and during this time it also captured images of one of Mars’ two small moon, Phobos.

What’s Up: December 2023 Skywatching Tips from NASA

NASA has shared its top picks for what to look out for in the night sky in the final month of the year.

Highlights include excellent views of the moon with various planets, a chance to see the peak of the Geminid meteor shower, and a rare opportunity to witness an asteroid passing by Earth.

Moon and planets

Check out the crescent moon appearing to get close with the planet Venus and the bright Spica star between December 7 and 10.

A week later, on December 17, you’ll see the moon hanging just below Saturn for the first few hours following sunset. Peering through binoculars will reveal the moon and the planet in the same field of view. At the same time, NASA also suggests trying to spot Saturn’s giant moon Titan as a faint dot just off to the side of Saturn.

On December 21 and 22, the moon appears close to Jupiter, which is easy to spot as it’s one of the brightest planets in the night sky.

Meteor shower

Following November’s Leonid meteor shower, this month it’s the turn of the Geminids. Described by NASA as “the year’s most reliable meteor shower,” with skywatchers potentially able to see as many as one meteor every minute.

The Geminids meteor shower peaks on the night of December 13 and the following morning. Viewers in the Northern Hemisphere can look for meteors as early as 9 or 10 p.m. on December 13, with the greatest number of meteors streaking across the sky between midnight and morning twilight.

Southern Hemisphere skywatchers will also have a view of the Geminids, but they’ll appear in the middle of the night and at about a quarter of the rate viewed in the Northern Hemisphere.

Asteroid

Last but not least, December offers a chance to see an asteroid zipping by Earth. NASA said there’s a chance you’ll be able to spot it with the naked eye, though a pair of binoculars or a telescope will offer a much better chance of tracking it down.

This month, asteroid Vesta is viewable from around 10 p.m. nightly, though the best chance to see it will come at around 1 or 2 in the morning when it’ll appear about halfway up the eastern sky, NASA says.

You’ll be able to spot Vesta in between the raised arm of Orion and the leg of Castor in Gemini. Around December 8, Vesta will appear between Betelgeuese and Propus. Watch NASA’s video at the top of this page for more information on how to track down Vesta.

Unique star system with six planets in geometric formation | Digital Trends

Unique star system with six planets in geometric formation | Digital Trends

Astronomers have discovered a rare star system in which six planets orbit around one star in an elaborate geometrical pattern due to a phenomenon called orbital resonance. Using both NASA’s Transiting Exoplanet Survey Satellite (TESS) and the European Space Agency’s (ESA) CHaracterising ExOPlanet Satellite (CHEOPS), the researchers have built up a picture of the beautiful, but complex HD110067 system, located 100 light-years away.

The six planets of the system orbit in a pattern whereby one planet completes three orbits while another does two, and one completes six orbits while another does one, and another does four orbits while another does three, and so one. The six planets form what is called a “resonant chain” where each is in resonance with the planets next to it.

It is this chain of resonances that makes the system so unusual. “Amongst the over 5,000 exoplanets discovered orbiting other stars than our sun, resonances are not rare, nor are systems with several planets. What is extremely rare though, is to find systems where the resonances span such a long chain of six planets,” explained one of the researchers, Hugh Osborn of the University of Bern, in a statement.

An astronomical waltz reveals a sextuplet of planets

The planets in this system are all of a type called sub-Neptunes, which are planets smaller than Neptune that are unlike any of the planets in our solar system, but are thought to be some of the most common exoplanets. Planets are thought to often form in resonance, due to the gravitational forces involved, however, this delicate balance is easily thrown out by perturbations such as a passing star or an impact from a large asteroid or comet.

Researchers are keen to investigate systems like HD110067 because it can show what a system might look like if it does not experience any of these dramatic events.

“We think only about 1% of all systems stay in resonance,” said researcher Rafael Luque of the University of Chicago. “It shows us the pristine configuration of a planetary system that has survived untouched.”

The research is presented in the journal Nature.

Rocky planets could form in extreme radiation environment | Digital Trends

Rocky planets could form in extreme radiation environment | Digital Trends

It takes a particular confluence of conditions for rocky planets like Earth to form, as not all stars in the universe are conducive to planet formation. Stars give off ultraviolet light, and the hotter the star burns, the more UV light it gives off. This radiation can be so significant that it prevents planets from forming from nearby dust and gas. However, the James Webb Space Telescope recently investigated a disk around a star thatseems like it could be forming rocky planets, even though nearby massive stars are pumping out huge amounts of radiation.

The disk of material around the star, called a protoplanetary disk, is located in the Lobster Nebula, one of the most extreme environments in our galaxy. This region hosts massive stars that give off so much radiation that they can eat through a disk in as little as a million years, dispersing the material needed for planets to form. But the recently observed disk, named XUE 1, seems to be an exception.

This is an artist’s impression of a young star surrounded by a protoplanetary disk in which planets are forming. ESO

The researchers used James Webb’s Mid-Infrared Instrument (MIRI) to identify water, carbon monoxide, carbon dioxide, hydrogen cyanide, and acetylene in the disk. Those are some of the building blocks for rocky planets and show that the disk is similar to other planet-forming disks, despite the high amount of UV radiation.

“We were surprised and excited because this is the first time that these molecules have been detected under these extreme conditions,” said one of the authors, Lars Cuijpers of Radboud University, in a statement.

The problem for this disk is that there are a number of nearby massive stars, so the disk is being bombarded by UV radiation from several sources. The disk does seem to be a bit smaller than expected, but it still appears that it could be capable of forming rocky planets. That means that rocky planets could form even in very extreme environments, if this particular disk is not an outlier.

“XUE 1 shows us that the conditions to form rocky planets are there, so the next step is to check how common that is,” said lead researcher María Claudia Ramírez-Tannus of the Max Planck Institute for Astronomy. “We will observe other disks in the same region to determine the frequency with which these conditions can be observed.”

The research is published in The Astrophysical Journal.

Hubble Space Telescope is in safe mode due to a gyro problem | Digital Trends

The Hubble Space Telescope has experienced a problem with its hardware and is currently in safe mode, with science operations paused until the fault can be corrected. The problem is with one of the telescope’s three operational gyros, which are used to control the direction in which the telescope points. When a fault like this is detected, the telescope automatically goes into a safe mode in which it performs only essential operations to prevent any damage to its hardware.

“The telescope automatically entered safe mode when one of its three gyroscopes gave faulty readings,” NASA wrote in a statement. “The gyros measure the telescope’s turn rates and are part of the system that determines which direction the telescope is pointed. While in safe mode, science operations are suspended, and the telescope waits for new directions from the ground.”

The telescope went briefly into safe mode on November 19, when the fault was detected, but engineers were able to get it operational again the next day. However, the fault with the gyro persisted, and the same thing happened on November 21 and November 23. Since then, the telescope has stayed in safe mode while the engineers work out how to fix the issue.

Although any problem with the telescope hardware isn’t great, this problem isn’t a threat to the life of the telescope. NASA says that Hubble could operate with just one of its gyros if necessary, though this would require reconfiguration and would be less efficient than using all three of the gyros, so fixing the faulty gyro would be preferable. The gyros were installed in 2009 during a servicing mission, and originally there were six of them. Now, three of them remain operational.

The servicing missions were necessary because when Hubble was launched in 1990, the images that it sent to Earth were blurry due to a tiny flaw in its primary mirror. A series of Space Shuttle missions took astronauts to the telescope between 1993 and 2009, at which times they made adjustments and repairs to keep the telescope operating. Hubble has now been active for over three decades.

Today, December 2, is the 30th anniversary of the first of these servicing mission, when a crew of seven worked to install a new camera and other components that turned Hubble’s images from blurry smears to the beautiful images we still see today.

Doctor Who Has Released an Official Recipe for Its Horrifying Curry

Image: BBC

When Doctor Who returned to our screens this past weekend in “The Star Beast,” it brought with it all sorts of weird and occasionally fearsome threats, from the mischievous Meep to the insectoid Wrarth Warriors. But perhaps nothing could send you scurrying behind the sofa than one single joke/threat: a fish curry made by Donna’s mom.

“Even AI Rappers are Harassed by Police” | AI Unlocked

When we reunite with Donna and her family in “The Star Beast,” the Nobles are having a bit of a rough time. Having given away the lottery earnings the Tenth Doctor had surreptitiously gifted her with just before his regeneration, Donna is struggling to make ends meet with her husband and daughter, having lost another job herself. One area she remains enriched though, whether she wants to be or not, is the help of her mother Sylvia, who has taken to preparing meals for her daughter’s family to help lighten the load. While we hear legendary tales of a truly gigantic sausage roll, only one of Sylvia’s food experiments has captured the hearts and minds, for better or worse, of Doctor Who fandom in the last week: her perfectly-comedically-timed explainer of what’s on the menu before everything goes sideways in Doctor Who’s trademark style. A tuna Madras curry!

It’s one of the funnier moments in an already funny episode. Jacqueline King’s delivery of the simple line is pitch-perfect, and it’s the perfect microcosm of writer/showrunner Russell T. Davies’s worldview for Doctor Who, the bizarre mundanity of human life clashing with the bizarre, alien world of adventuring in Time and Space. But also: the idea of a tuna curry is just bizarrely gross to a lot of people, hence why Doctor Who fans have become obsessed. Remember, this is the fanbase that willingly tried Fish Fingers and Custard after the Eleventh Doctor snacked on it in his debut episode. A canned tuna curry is practically fine dining in comparison. But while “The Star Beast” left Sylvia’s tuna Madras behind in its alien mayhem, have no fear, culinarily curious Whovians: the BBC has provided an official recipe so you can make it at home. Check it out below!

Ingredients

  • 2 teaspoons of ground cumin
  • 1 teaspoon of ground coriander
  • Half teaspoon of turmeric
  • 1 teaspoon of hot chilli powder
  • 1 teaspoon of ginger
  • Salt (to taste)
  • 1 onion
  • Chopped 5 cloves of garlic
  • Chopped 2 tins of tuna
  • Drained 1 tin of tomatoes
  • Half a jar of black olives

Method

  1. Fry the onion for five minutes until golden brown.
  2. Add the garlic, stir for two minutes.
  3. Mix in the spices, stir quickly, add in two tins of tuna.
  4. Stir again twice.
  5. Add the tin of tomatoes and the olives.
  6. Bring to a boil until the sauce thickens.
  7. Turn down low for ten minutes.
  8. Serve.

Although largely unheard of (perhaps for good reason, looking at this ingredient list), the tuna Madras is apparently a staple in Davies’ family, according to the commentary track for “The Star Beast.” So whether you want to either feast on the fuel behind one of the most influential minds of British television, or you need something to eat when Doctor Who returns this weekend… maybe you’re brave enough to try this and see what the Nobles missed out on?
