SpaceX Starship launch countdown

Published

 on

Elon Musk’s stated goal of putting humans on Mars relies heavily on the development of a next-generation reusable spacecraft, and now Starship (formerly known as Big Falcon Rocket or BFR) is ready for its first orbital test flight.

It’s not the “six months” goal Musk projected in 2019, but after a number of suborbital tests that included some terrific successes and fantastic, fiery failures, the big day is finally almost here. Now that the FAA has signed off, SpaceX says that its first window for a test launch from its Boca Chica, Texas, “Starbase” will open at 7AM CT (8AM ET).

SpaceX says it’s targeting sometime around 9AM ET on Monday morning for its test launch, with verification that the craft is “go for propellant loading” scheduled to begin two hours before that. If all goes according to plan, the Starship will fly to orbit after separating from its Super Heavy booster rocket about three minutes into the trip, then splashdown in the Pacific Ocean near Hawaii.

The entire trip should take about 90 minutes to complete, and SpaceX will livestream the events on its YouTube channel with a video feed starting about 45 minutes before liftoff.

    SpaceX’s Starship rocket has been cleared for launch by the Federal Aviation Administration (FAA), meaning it could take its first orbital flight test as soon as next week, as reported earlier by CNN.

    With the help of SpaceX’s Super Heavy rocket, Starship is the spacecraft that’s designed to ferry crew and cargo to Earth orbit, the Moon, and Mars. SpaceX says it’s targeting a Starship launch from the company’s Texas Starbase “as soon as” April 17th.

    Last week, SpaceX announced it’s poised to launch the fully stacked Starship spacecraft for a first orbital flight test following a launch rehearsal this week and pending regulatory approval. Now SpaceX CEO Elon Musk is confirming it’s ready, with launch “trending towards near the end of third week of April,” Musk wrote in a tweet on Monday.

    Starship is SpaceX’s long-awaited flagship spacecraft that’s designed to take astronauts and payloads to deep space — including the Moon and, of course, Mars. Most importantly, the parts are designed to be reusable, and it is paired with a massive booster known as the Super Heavy to get it off the Earth’s surface.

  • 31 out of 33 isn’t too bad.

    Elon Musk says that only 31 of the 33 engines on SpaceX’s Starship booster actually fired, but the static fire test was still a thing to behold. Despite that, the test went really well otherwise according to the people over at the NASA Spaceflight channel, paving the way towards the ship actually launching.

    They should start playing replays soon, so tune in if you want to see some flames.

    A former SpaceX engineer published an essay today describing alleged age discrimination he says he experienced while he was at the company. “I saw my work roles gradually transferred to younger engineers who fit the company’s ‘frat bro’ mold,” John Johnson writes in the essay published on the platform Lioness.

    “In the culture, in the environment of SpaceX, old people are rare. And when I say old people, I mean anyone over 40,” Johnson, who is 62, tells The Verge. In a job interview for his role at SpaceX, Johnson says he was asked whether he’d “be okay” working with young colleagues.

    A group of former SpaceX employees has filed unfair labor practice charges with the National Labor Relations Board, The New York Times reports. The employees say they were fired illegally after putting together a letter that called on the company to strengthen its “zero-tolerance policies” following sexual harassment allegations against Elon Musk.

    Nine employees were ultimately fired after the letter came out in June, the Times reports, eight of whom filed the charges with federal regulators. The letter, first reported on by The Verge, asked SpaceX executives for three things: to curb “Elon’s harmful Twitter behavior,” to define and enforce the company’s sexual harassment policies, and ensure that all leadership is held accountable for violating such policies.

  • The first time Anthony Gomez saw one of SpaceX’s Starship prototypes take flight, he watched it on a projector. He was far away from the humid Texas coast, where the actual launch was taking place. Instead, he was sitting in his house in Florida with his girlfriend.

    On the wall of his home, Anthony admired the Starship rocket as it careened through the sky. All three of the Raptor engines cut off when the spaceship reached an altitude of roughly 41,000 feet, and the massive steel vessel began to plummet back to Earth, pitched over on its side, looking like a grain silo in free fall. Just before reaching the landing pad, its engines reignited, and the vehicle rapidly turned upright again as it prepared to touch down. But the spacecraft came down too fast, hitting the ground hard and bursting apart in a massive explosion. Afterward, only a charred patch of Earth remained where Starship once stood — a disappointment.

    It’s always fun to check in with SpaceX, Elon Musk’s least dysfunctional company — oh wait, what’s this? The workers at SpaceX are upset?

    Last week, as first reported by The Verge, a group of SpaceX workers wrote a letter to Musk about his tweets. “Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks,” the letter states. “As our CEO and most prominent spokesperson, Elon is seen as the face of SpaceX — every Tweet that Elon sends is a de facto public statement by the company. It is critical to make clear to our teams and to our potential talent pool that his messaging does not reflect our work, our mission, or our values.”

    The Federal Aviation Administration (FAA) has determined that SpaceX’s plans for the company’s massive Starbase launch site in South Texas will have some environmental impact on the surrounding land and area — but not enough to require a full environmental impact statement. Now, SpaceX will need to make more than 75 changes to its proposal for the Starbase facility if the company wants to avoid additional review and eventually receive a license from the FAA to launch its new Starship rocket to orbit from the site.

    SpaceX’s Starbase facility is located in a small town called Boca Chica, Texas, right on the southern tip of Texas along the Rio Grande river and the US-Mexico border. For the last few years, SpaceX has used the site to construct full-scale prototypes of Starship, the company’s next-generation monster rocket designed to take people and cargo to deep-space destinations like the Moon and Mars. SpaceX has already conducted various high-altitude test flights with Starship prototypes from Starbase, but now, the company hopes to actually launch Starship to space for the first time and send the vehicle to orbit.

  • SpaceX CEO Elon Musk says he’s hopeful that his company’s launch facility in Boca Chica, Texas, will receive regulatory approval to launch by March and that the first orbital launch of SpaceX’s new Starship rocket will take place sometime this year.

    Musk made these comments during his first presentation on Starship since 2019, which he gave last night at the company’s test facility in Boca Chica, Texas. Standing in front of a full stacked prototype of the rocket that towered high over the stage, Musk provided an overview of some of the latest specs of the vehicle, why he wants to pursue deep space travel, and when he expects to make all these plans happen.

    A group of former SpaceX employees are coming forward about their experience working at the commercial rocket company, claiming that there is a culture of sexual harassment in the workplace and that managers and the human resources department handled complaints poorly.

    The individuals are speaking out in light of an essay published by one former employee, Ashley Kosak, who left SpaceX in November. In her account, Kosak details multiple instances of being groped and feeling uncomfortable after fending off sexual advances by her male co-workers. Four additional people who spoke with The Verge described their own troubling experiences at SpaceX or witnessing other women and nonbinary people being harassed. In three cases reviewed by The Verge, SpaceX HR was made aware of the allegations and had inconsistent responses that the employees felt were inadequate.

    Richard Branson’s extravagant jaunt to space on Sunday signaled the dawning of a new space age — for the few people that can afford it. Jeff Bezos is about to set off on a similar excursion next Tuesday when he launches to space with three others on his company Blue Origin’s first crewed flight. The two billionaires are validating their companies’ tourist-tailored rockets and, they say, fulfilling lifelong dreams to get a brief taste of space.

    But what Virgin Galactic’s mission on Sunday proved, and what Bezos’ flight will similarly show, is that space is almost open, not for you and me or the general public, but for more billionaires.

    SpaceX plans to have its first Starship test flight to orbit launch from Texas and splash down off the coast of an island in Hawaii, according to a document the company filed with the Federal Communications Commission on Thursday. The orbital flight test would mark the first time SpaceX stacks both elements of its massive Starship system together, the next key development step in its attempt to build a rocket that could one day land on Mars.

    As outlined in the document, a super heavy booster stage will launch Starship from SpaceX’s Boca Chica, Texas, facilities and separate in midair nearly three minutes into flight. About five minutes later,that booster stage will return back to Earth and splash down in the Gulf of Mexico — or as SpaceX puts it: it will “perform a partial return and land in the Gulf of Mexico approximately 20 miles from the shore.”

    SpaceX’s latest Starship prototype landed on Wednesday for the first time after carrying out a high-altitude test flight in Texas — but exploded minutes later on its landing pad. The rocket, an early test version called SN10, demonstrated a few complex dances in mid-air before clinching a soft touch down, aiming to nail a key milestone in Elon Musk’s campaign to build a fully reusable rocket system.

    After aborting an initial launch attempt earlier in the day, the prototype lifted off at 6:14pm ET and soared 6 miles above SpaceX’s Boca Chica, Texas facilities. Unlike the last two tests with SN8 and SN9, which launched successfully but exploded on their landing attempts, SN10 stuck a lopsided landing on a slab of concrete not far from its launchpad, appearing to survive its daring landing maneuver for a few moments before being consumed in a fireball.

    During a test flight on Wednesday, SpaceX flew a prototype of its next generation Starship rocket to its highest height yet in the skies above Texas — but failed to stick the landing, with the vehicle exploding when it hit the ground. Propelled by three main engines, the vehicle launched to a target altitude of nearly 8 miles, or 12.5 kilometers, before crash landing into the Earth.

    The nearly seven-minute test flight took off at around 5:45PM ET from SpaceX’s facility at Boca Chica, Texas. The prototype climbed to its target altitude, but during the flight, two of its three main engines seemingly shut down while it ascended. Eventually all three engines cut off, and SpaceX attempted to perform a “bell flop” maneuver, with the vehicle falling horizontally on the way down to Earth. Just before reaching the ground, the prototype reignited its engines — but the vehicle came in way too fast and blew apart when it hit the ground.

    A fourth prototype of SpaceX’s next generation Starship rocket exploded right after a test at the company’s south Texas test site on Friday. Shortly after SpaceX ignited the engine on the test rocket, a massive fireball engulfed the vehicle in flames, leaving very little hardware still standing and apparently causing damage to the test site.

    The failed test comes just a day before SpaceX is set to perform an unrelated launch for NASA that will send two astronauts to the International Space Station. That historic mission will take place out of Cape Canaveral, Florida, on SpaceX’s workhorse Falcon 9 rocket, which has flown close to 100 times before.

    On Saturday night, SpaceX CEO Elon Musk gave a presentation in Boca Chica, Texas, on the development of his company’s next generation rocket, called Starship. Starship is meant to fly hundreds of passengers to deep-space destinations like the Moon and Mars. Flanked by a giant prototype of the vehicle, Musk vowed that Starship could fly to orbit as soon as six months from now, and carry its first passengers sometime next year.

    “This thing is going to take off, fly to 65,000 feet — about 20 kilometers — and come back and land in about one to two months,” Musk said, referring to the stainless steel prototype behind him. The giant test article stood next to a SpaceX Falcon 1 rocket, the first vehicle the company put into orbit. The staging was symbolic, especially since the presentation occurred on the anniversary of SpaceX’s first flight to orbit with the Falcon 1.

  • SpaceX CEO Elon Musk would like his Starship spacecraft to make it to orbit in six months, he said during an evening presentation on September 28.  The event seemed aimed squarely at fans, with little new information and a lot of SpaceX history.

    “This is going to sound totally nuts, but I think we want to try to reach orbit in less than six months,” Musk said. “Provided the rate of design improvement and manufacturing improvement continues to be exponential, I think that is accurate to within a few months.”

    A test version of SpaceX’s next-generation spacecraft, the Starship, successfully ignited its onboard engine for the first time today — though the vehicle didn’t go very far. The ignition was a test known as a static fire, meant to try out the engine while the vehicle remained tethered to the Earth. However, today’s test marked the first time this vehicle lit up its engine, and it could pave the way for short “hop” flights in the near future.

    This particular vehicle, referred to as “Starhopper,” is meant to test out the technologies and basic design of the final Starship vehicle — a giant passenger spacecraft that SpaceX is making to take people to the Moon and Mars. The stainless steel Starship is supposed to launch into deep space on top of a massive booster called the Super Heavy, which will be capable of landing back on Earth after takeoff just like SpaceX’s current Falcon 9 rocket fleet. And when complete, the Starship/Super Heavy combo should be capable of putting up to 220,000 pounds (100,000 kilograms) into low Earth orbit, according to SpaceX CEO Elon Musk, making it one of the most powerful rockets ever made.

Quirks and Quarks9:05This researcher wants a new particle accelerator to use before she’s dead

Physicists exploring the nature of reality need ever more capable particle colliders, so they’re exploring a successor to the Large Hadron Collider in Europe. But that new machine is at least decades away. Tova Holmes, an assistant professor at the University of Tennessee, Knoxville, is one of the physicists calling for a different kind of collider that can come online before the end of her career – or her life. This device would use a particle not typically used in particle accelerators: the muon.

The proposed new particle accelerator would require an even larger tunnel, one that’s over 100 kilometres. Physicists calling for the development of a muon accelerator say it will require much less space. (Samuel Joseph Hertzog/CERN)

It turns out that acting out your anger might not be the best way to get rid of it. Sophie Kjaervik, a researcher at Virginia Commonwealth University in Richmond, Va., analyzed 154 studies of the different ways to deal with anger. Her results, published in the journal Clinical Psychology Review, suggest that techniques that reduce your heart rate and calm your mind are more effective than blowing off steam.

Quirks and Quarks8:37High intensity wildfires may release toxic forms of metals

Wildfire smoke might be more dangerous than you think. A recent study in the journal Nature Communications found that when wildfires pass over soils or rocks rich in a normally harmless metal called chromium, it is transformed into a toxic form. The hotter and more intense the wildfire is, the more of this metal becomes toxic. Scott Fendorf, an Earth system science professor at Stanford University, said this study shows we should factor in the type of geology wildfires pass over to provide more targeted air quality warnings about smoke risks.

Dragonfly: NASA greenlights most important mission of the century – Earth.com

Published

 on


In a remarkable development, NASA has given the green light to the Dragonfly mission, a revolutionary rotorcraft designed to investigate the complex chemistry of Saturn‘s moon Titan.

This confirmation allows the mission to proceed with the final design, construction, and testing of the spacecraft and its scientific instruments.

Deciphering the prebiotic chemistry on Titan

The Dragonfly mission, led by Dr. Melissa Trainer of NASA’s Goddard Space Flight Center, will carry a cutting-edge instrument called the Dragonfly Mass Spectrometer (DraMS).

300x250x1

This powerful tool will help scientists delve into the intricate chemistry at work on Titan, potentially shedding light on the chemical processes that led to the emergence of life on Earth, known as prebiotic chemistry.

“We want to know if the type of chemistry that could be important for early pre-biochemical systems on Earth is taking place on Titan,” explains Dr. Trainer, a planetary scientist and astrobiologist specializing in Titan.

Titan: Dragonfly’s target

Titan, the largest moon of Saturn, is shrouded in a dense nitrogen-rich atmosphere, bears a striking resemblance to Earth in many ways. With a diameter of 5,150 kilometers, Titan is the second-largest moon in our solar system, surpassed only by Jupiter’s Ganymede.

Dense atmosphere and unique climate

One of Titan’s most distinctive features is its thick atmosphere, which is composed primarily of nitrogen and methane. This dense atmosphere creates a surface pressure 1.5 times higher than Earth’s, making it the only moon in our solar system with a substantial atmosphere.

The presence of methane in Titan’s atmosphere leads to a fascinating hydrological cycle, similar to Earth’s water cycle, but with methane as the primary liquid.

Titan’s surface is dotted with numerous lakes and seas of liquid hydrocarbons, predominantly methane and ethane. These liquid bodies, some of which are larger than the Great Lakes on Earth, are the result of Titan’s unique climate and atmospheric conditions.

The Cassini mission, which explored the Saturn system from 2004 to 2017, provided stunning images and data of these extraterrestrial lakes and seas.

Dragonfly mission to search Titan for prebiotic chemistry and life

The complex chemistry occurring on Titan’s surface and in its atmosphere has drawn significant attention from astrobiologists.

With its abundant organic compounds and the presence of liquid methane, Titan is considered a prime candidate for studying prebiotic chemistry and the potential for life to emerge in environments different from Earth.

Beneath Titan’s icy crust lies another intriguing feature: a global subsurface ocean of liquid water and ammonia. This ocean, which is believed to be salty and have a high pH, may potentially host microbial life.

The presence of this subsurface ocean, along with the unique chemistry on Titan’s surface, makes this moon a fascinating target for future exploration and scientific research.

Pushing the boundaries of rotorcraft exploration

Nicky Fox, associate administrator of the Science Mission Directorate at NASA Headquarters, emphasized the significance of the Dragonfly mission, stating, “Exploring Titan will push the boundaries of what we can do with rotorcraft outside of Earth.”

Titan’s unique characteristics, including its abundant complex carbon-rich chemistry, interior ocean, and past presence of liquid water on the surface, make it an ideal destination for studying prebiotic chemical processes and the potential habitability of an extraterrestrial environment.

Innovative design and cutting-edge technology

The Dragonfly robotic rotorcraft will leverage Titan’s low gravity and dense atmosphere to fly between different points of interest on the moon’s surface, spanning several miles apart.

This innovative approach allows the entire suite of instruments to be relocated to new sites once the previous one has been thoroughly explored, providing access to samples from diverse geological environments.

DraMS, developed by the same team responsible for the Sample Analysis at Mars (SAM) instrument suite aboard the Curiosity rover, will analyze surface samples using techniques tested on Mars.

Dr. Trainer emphasized the benefits of this heritage, stating, “This design has given us an instrument that’s very flexible, that can adapt to the different types of surface samples.”

Dragonfly mission challenges and funding

The Dragonfly mission successfully passed its Preliminary Design Review in early 2023. However, due to funding constraints, the mission was asked to develop an updated budget and schedule.

The revised plan, presented and conditionally approved in November 2023, hinged on the outcome of the fiscal year 2025 budget process.

With the release of the president’s fiscal year 2025 budget request, Dragonfly is now confirmed with a total lifecycle cost of $3.35 billion and a launch date set for July 2028.

This reflects a cost increase of approximately two times the initially proposed cost and a delay of more than two years from the original selection in 2019.

Despite the challenges posed by funding constraints, the COVID-19 pandemic, supply chain issues, and an in-depth design iteration, NASA remains committed to the Dragonfly mission.

Additional funding has been provided for a heavy-lift launch vehicle to shorten the mission’s cruise phase and compensate for the delayed arrival at Titan.

Rigorous testing and validation

To ensure the success of the Dragonfly mission, researchers on Earth have conducted extensive testing and validation of the designs and models for the nuclear-powered, car-sized drone.

The mission team has carried out test campaigns at NASA’s Langley Research Center, utilizing the Subsonic Tunnel and the Transonic Dynamics Tunnel (TDT) to validate computational fluid dynamics models and gather data under simulated Titan atmospheric conditions.

Ken Hibbard, Dragonfly mission systems engineer at APL, emphasized the importance of these tests, stating, “All of these tests feed into our Dragonfly Titan simulations and performance predictions.”

As the Dragonfly mission progresses, it marks a new era of exploration and scientific discovery. Dr. Trainer expressed her excitement, saying, “Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next steps on this mission.”

Turning science fiction into fact with the Dragonfly mission

In summary, the Dragonfly mission embodies the essence of human curiosity and the relentless pursuit of knowledge. As NASA prepares to send this revolutionary rotorcraft to the alien world of Titan, we stand on the brink of a new era of exploration and discovery.

With its innovative design, cutting-edge technology, and the unwavering dedication of the mission team, Dragonfly will unlock the secrets of prebiotic chemistry and shed light on the potential for life beyond Earth.

As we eagerly await the launch of this titanic mission, we can only imagine the wonders that await us on Saturn’s enigmatic moon. The Dragonfly mission is a testament to the indomitable human spirit and our boundless capacity to push the frontiers of knowledge.

In the words of Ken Hibbard, “With Dragonfly, we’re turning science fiction into exploration fact,” and that fact will undoubtedly inspire generations to come.

Marine plankton could act as alert in mass extinction event: UVic researcher – Langley Advance Times

Published

 on


A University of Victoria micropaleontologist found that marine plankton may act as an early alert system before a mass extinction occurs.

With help from collaborators at the University of Bristol and Harvard, Andy Fraass’ newest paper in the Nature journal shows that after an analysis of fossil records showed that plankton community structures change before a mass extinction event.

“One of the major findings of the paper was how communities respond to climate events in the past depends on the previous climate,” Fraass said in a news release. “That means that we need to spend a lot more effort understanding recent communities, prior to industrialization. We need to work out what community structure looked like before human-caused climate change, and what has happened since, to do a better job at predicting what will happen in the future.”

According to the release, the fossil record is the most complete and extensive archive of biological changes available to science and by applying advanced computational analyses to the archive, researchers were able to detail the global community structure of the oceans dating back millions of years.

A key finding of the study was that during the “early eocene climatic optimum,” a geological era with sustained high global temperatures equivalent to today’s worst case global warming scenarios, marine plankton communities moved to higher latitudes and only the most specialized plankton remained near the equator, suggesting that the tropical temperatures prevented higher amounts of biodiversity.

“Considering that three billion people live in the tropics, the lack of biodiversity at higher temperatures is not great news,” paper co-leader Adam Woodhouse said in the release.

Next, the team plans to apply similar research methods to other marine plankton groups.
