Eminent Officials Say NASA Facilities Some Of The “Worst” They've Ever Seen

Image More details: See here

"NASA's problem is it always seems to have $3 billion more program than it has of funds," said Norm Augustine, chair of the National Academies panel chartered to examine the critical facilities, workforce, and technology needed to achieve NASA's long-term strategic goals and objectives. Augustine said a similar statement could sum up two previous high-level reviews of NASA's space programs that he chaired in 1990 and 2009. But the report released Tuesday put NASA's predicament in stark terms.

Around 83 percent of NASA's facilities are beyond their design lifetimes , and the agency has a $3.3 billion backlog in maintenance. When you consider NASA's $250 million estimate for normal year-to-year maintenance, it would take a $600 million uptick in NASA's annual budget for infrastructure repairs to catch up on the backlog within the next 10 years.

To members of Congress or the White House, backing a new NASA mission to the Moon or a space telescope to probe the deepest reaches of the Universe is often more attractive than investing in facility maintenance. The former initiatives grab headlines and create jobs. Most of NASA's facilities across the country are rated "marginal to poor" in condition, according to a presentation to the National Academies last year by Erik Weiser, NASA's director of facilities and real estate.

"In NASA's case, the not-uncommon tendency in a constrained budget environment to prioritize initiating new missions as opposed to maintaining and upgrading existing support assets has produced an infrastructure that would not be viewed as acceptable under most industrial standards," the panel wrote in its report. "In fact, during its inspection tours, the committee saw some of the worst facilities many of its members have ever seen."

NASA is dealing with these infrastructure shortfalls as the agency pursues the most challenging missions in its 66-year history.

"Viewed in terms of both the architectural complexity and the technical complexity, NASA today—for example, in the Artemis program to land on the Moon a few years from now—is taking on challenges that far surpass anything that was faced in the Apollo program," Augustine said.

A four-person crew of civilians on board SpaceX's Polaris Dawn mission unlocked the hatch of their capsule and made history as the first group of non-government astronauts to conduct a spacewalk.

SpaceX hosted a live webcast of the event — also known as an extravehicular activity (EVA) — which kicked off at 6:12 a.m. ET.

The entire SpaceX Crew Dragon vehicle propelling and protecting the crew was depressurized and exposed to the vacuum of space — a dangerous and historic milestone in the Polaris Dawn crew's five-day journey through Earth's orbit. The mission has already set records, traveling farther into space than any human since NASA's Apollo program concluded more than 50 years ago.

The crewmates — which includes Shift4 Payments CEO Jared Isaacman, Polaris Dawn's financer; his close friend and former US Air Force pilot Scott "Kidd" Poteet; and SpaceX engineers Anna Menon and Sarah Gillis — had prepared for this spacewalk since taking flight at 5:23 a.m. ET Tuesday.

The team slowly underwent what's called a "pre-breathe" process, a step intended to purge their blood of nitrogen to prevent the gas from bubbling — a potentially lethal condition — as they experienced the vacuum of space.

He walked up a mobility aid — essentially a ladder that SpaceX has dubbed "skywalker" — to venture into the endless void and took in the views.

"Back at home we all have a lot of work to do, but from here — looks like a perfect world," Isaacman said.

Gillis and Isaacman were the only two crewmembers to actually exit the spacecraft, and they did so for a combined total of roughly 20 minutes.

Gillis exited the capsule for about 10 minutes after Isaacman returned to his seat. She spent her time outside wiggling around in her spacesuit — as expected — to help test out its mobility.

Asteroid Apophis Has The Tiniest Chance Of Hitting Earth In 2029

In a bit of ominous news befitting a Friday the 13th : It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years, when it is expected to make a close flyby on April 13, 2029 − yes, a Friday the 13th. But we'd have to be extremely unlucky.

That's according to new findings from astronomer Paul Wiegert , who previously ruled out the possibility of a collision altogether in another study in March . But Wiegert, of Western University in Canada, apparently decided to revisit the possibility of Apophis being struck by small space rocks like the ones that frequently and unpredictably strike Earth.

If that were to happen – and that's a big "if" – a remote chance exists that Apophis could be sent careening into Earth, according to a new study published in August in The Planetary Science Journal .

Astronomers have long had their eye on the notorious Apophis, which was initially believed to pose a serious threat to Earth upon its discovery in 2004.

In the new study, Weigert used computer models to simulate the likelihood of an undiscovered asteroid hitting Apophis off its course within the next five years and sending it onto a doomed encounter with Earth. Wiegert also analyzed what size an object would need to be to knock Apophis off course and put it on a trajectory to crash into Earth beyond 2029.

A Chinese "reusable experimental spacecraft" believed to be the country's secretive space plane has landed back on Earth after more than eight months in orbit – the latest development in a largely covert race between the United States and China to hone such technology.

China's spacecraft blasted into orbit last December – two weeks ahead of the latest launch of the US military's own Boeing X-37B uncrewed space plane – on the third known orbital mission of such a Chinese spacecraft.

Some 268 days later, the spacecraft returned to an unnamed landing site, according to a brief September 6 announcement from state news agency Xinhua, which declared its test mission a "complete success."

China's development of the vehicle, about which little is publicly known, comes after recent years of striving to catch up to the US, long the world's preeminent space power, for dominance in orbit and beyond.

The term "space plane" often evokes NASA's Space Shuttle, which flew 135 missions from 1981 to 2011, carrying astronauts into orbit and helping to construct the International Space Station. It might also recall the Soviet Union's ill-fated Buran space shuttle, which completed one successful uncrewed flight in 1988 before being discontinued.

But the newer planes currently being tested in orbit by the US and China are believed to be smaller than the shuttle and uncrewed. The US X-37B is operated by the military, while China has not said whether the program believed to be linked to its recently landed spacecraft is civilian or military.

A MYSTERIOUS object orbiting our planet has become a hodgepodge of conspiracy theories, with some claiming it might be a 13,000-year-old alien spaceship.

From a millennia-old spacecraft to a UFO shot down by the Illuminati, tales surrounding the ⁘Black Knight Satellite⁘ go back decades, fuelling what may be one of the greatest space myths.

The legend's origins are often traced back to the early 20th century when none other than Nikola Tesla claimed to have received strange radio signals from space in 1899.

While these signals were likely natural or man-made phenomena, they have been retroactively tied to the Black Knight legend by conspiracy theorists.

Fast forward to the 1920s and 1930s, when radio operators began reporting what they called Long Delay Echoes (LDEs).

These were unexplained echoes of radio signals, returning after an unusually long delay, sometimes several seconds.

The phenomenon puzzled scientists, and while they eventually proposed various theories—ranging from ionospheric reflections to equipment malfunctions—some conspiracy theorists found a more intriguing explanation.

The plot thickened in 1954, when media reports, fueled by UFO researcher Donald Keyhoe, claimed that the US Air Force had detected two unidentified satellites orbiting Earth.

Alien Star Could Have Side-swiped Our Solar System Closer Than Voyager

Image Source: Visit website

Headlines:

Our solar system might still bear the scars from an extremely close shave with an alien star. Such an encounter – the closest pass we know of – would have shaken up objects on the outskirts and might even mean there's no Planet Nine after all.

Some of these objects have bizarre behavior that doesn't make sense yet. Some have eccentric , or very elongated, orbits. Others have highly inclined orbits, meaning they swing above and below the orbital disk that most other objects stick to. A few even orbit backwards , traveling against the traffic of almost everything else in the solar system.

To explain these eccentricities, astronomers have proposed the existence of a ninth large planet , with a mass of Mars or bigger, lurking in the dark out there. Its gravitational influence could theoretically cause these signs, but extensive searches have so far turned up no direct trace of such a Planet Nine.

Now, astronomers in the Netherlands have suggested a new explanation – a close encounter with another star billions of years ago. To test the idea, the team conducted more than 3,000 simulations modeling what happens when stars of different masses fly through planetesimal disks of different widths, passing at different distances. And sure enough, they were able to recreate the weird orbits seen in the modern solar system.

"The best match for today's outer solar system that we found with our simulations is a star that was slightly lighter than our Sun – about 0.8 solar masses," said Amith Govind, co-author of the study. "This star flew past our sun at a distance of around 16.5 billion km (10.3 billion miles). That's about 110 times the distance between Earth and the Sun, a little less than four times the distance of the outermost planet Neptune."

M-Dwarf Planets Are Likely Habitable — But They Would Change Humans In This Weird Way

Image Reference: See here

Headlines:

There are billions of potentially habitable planets in our galaxy. How do we arrive at this number? The Milky Way has between 100 billion and 400 billion stars.

Seventy percent of these are tiny, cool red dwarfs, also known as M-dwarfs . A detailed exoplanet survey published in 2013 estimated that 41 percent of M-dwarf stars have a planet orbiting in their "Goldilocks" zone, the distance at which the planet has the right temperature to support liquid water.

Rocky planets orbiting in an M-dwarf's habitable zone are called M-Earths. M-Earths differ from our Earth in fundamental ways. For one thing, because M-dwarf stars are much cooler than the Sun, they are close in, which makes the gravitational pull of the star on the planet immensely strong.

The star's gravity pulls harder on the near side of the planet than the far side, creating friction that resists and slows the planet's spin over aeons until spin and orbit are synchronized. This means most M-Earths are probably tidally locked, which is when one hemisphere always faces the Sun while the other always faces away.

A Soyuz Craft With 2 Russians And 1 American Docks At The International Space Station

Image More details: Visit website

A Soyuz spacecraft carrying two Russians and an American has docked at the International Space Station

The capsule atop a towering rocket set off from a Russian launch facility in Baikonur, Kazakhstan, and docked with the space station after two orbits of the Earth, a fast trip compared with some that have lasted for days.

The crew already aboard the station were performing a lengthy series of system checks before those in the capsule can enter.

The mission commander is Alexei Ovchinin, with Russian compatriot Ivan Vagner and American Donald Pettit in the crew.

The launch took place without obvious problems and the Soyuz entered orbit eight minutes after liftoff, a relief for Russian space authorities after an automated safety system halted a launch in March because of a voltage drop in the power system.

On the space station, Pettit, Vagner and Ovchinin will join NASA's Tracy Dyson, Mike Barratt, Matthew Dominick, Jeanette Epps, Butch Wilmore and Suni Williams, and Russians Nikolai Chub, Alexander Grebenkin and Oleg Kononenko.

Wilmore and Williams have remained on the station long past their scheduled return to Earth. They arrived in June as the first crew of Boeing's new Starliner capsule. But their trip to the orbiting laboratory was marred by thruster troubles and helium leaks, and NASA decided it was too risky to return them on Starliner.

Astronomers have hunted for this planet since 2016. Could one more year of searching finally solve the mystery?

Well, if it's so large, why haven't we found this Planet X yet then? Good question. Using the Oort Cloud as an approximate boundary and considering it extends somewhere between 1,000 Astronomical Units (AU) and 100,000 AU (or about 9.3 trillion miles) would mean that our solar system is two to three light-years wide.

Spotting a planet that far out is no easy task. Planet Nine, if it exists, is thought to be around 500 times farther from the Sun than Earth. So, it would be incredibly faint. Even the best telescopes have struggled to detect it. But the Vera C. Rubin Observatory is different.

Set to begin operations in late 2025, this groundbreaking telescope will be equipped with an 8.4-meter mirror and the world's largest digital camera, capable of capturing the faint light reflected from objects deep in the solar system. According to Brown, the Vera C. Rubin Observatory will be able to peer farther into space than any ground-based telescope before it, giving astronomers their best chance yet to locate Planet Nine. "It's very possible that Planet Nine will be found within the first year of the observatory," Brown said .

Finding Planet Nine would mark one of the most significant astronomical discoveries of the 21st century. Beyond simply identifying a new planet, it would rewrite much of what we know about the solar system's history and evolution.

Astronomers believe that Planet Nine could help explain how the outer reaches of our solar system took shape and why some of its most distant objects behave so strangely. It could also shed light on the formation of similar giant planets orbiting other stars in the galaxy.

NASA Pulls Satellites From Bezos's Blue Origin As Musk Touts Mars Landing Timeline | Inc.Com

Image Source: Visit website

Headlines:

Blue was slated to fly NASA's Mars-exploring Escapade satellites as passengers on the imminent first flight of its 320-foot tall New Glenn rocket. NASA signaled late last week that it had changed its mind, saying it was halting all pre-launch preparations for the twin satellites to avoid "significant cost, schedule, and technical challenges associated with potentially removing fuel from the spacecraft in the event of a launch delay." It carefully noted that such a delay "could be caused by a number of factors," SpaceNews reported .

Behind this careful wording, it's easy to see that NASA's management had become wary of the way Blue Origin was preparing for New Glenn's first launch. Complex orbital mechanics mean that Escapade had to leave Earth in a narrow window between October 13 and 21, leaving no margin for error in preparations for New Glenn's first flight. The rocket has been developed very, very slowly since 2013, mostly in secret, in keeping with the company's motto "Gradatim Ferociter," which translates as "step-by-step, ferociously."

Blue critics have long pointed out that New Glenn is far behind schedule, and the company eemed to step into a high gear and race to launch the rocket into space only after Bezos hired a fresh, new CEO , David Limp--formerly a senior vice president at Amazon--to run the company at the end of 2023.

Imagine a world without SpaceX. The current revolution in commercial space travel would not have taken place. Elon Musk's rocket company is wildly successful because it has provided launch services that are not only more reliable but degrees of magnitude cheaper than previous rocket companies were able to achieve.

The main reason that the SpaceX Falcon 9 and Falcon Heavy launches are so inexpensive is that the company has solved the reusability problem. The first stages of these rockets return to drone ships or onshore landing zones to be refurbished and relaunched. Except for one recent failure, SpaceX has routinely been landing Falcon's first stages for several years.

Without SpaceX, the Starliner astronauts, now stuck on the International Space Station , would be faced with the stark choice between a risky return on the spaceship they flew into space in or begging for a ride home on a Russian Soyuz.

Without SpaceX and the in-development Starship rocket, America would not return astronauts to the moon anytime soon. China would likely be the next nation to accomplish that feat.

Without SpaceX, there would be no prospect for private space stations, a moon base, or Elon Musk's dream of a city on Mars.

Commercial space flights such as Jared Isaacman's Inspiration4 and Polaris Dawn would be pipe dreams. Starlink, which promises to bind the world together in a telecommunications web, would be pie in the sky. The military would have a harder time securing space from foreign enemies.

The British Army has recruited Terminator-style robots to help train soldiers in battleground scenarios.

If the soldier becomes angry, the robot, called SimStriker, can become hostile and fire BB pellets from its abdomen. In contrast, a calmer soldier will help control the situation.

In one battleground scenario, soldiers must face SimStriker in a village where locals need food, electricity and medical supplies, The Telegraph reports.

It comes amid a move to use better technology and AI to prepare for complex future warfare. Pictured: Soldiers in Salisbury demonstrate the EXO Insight glasses which are an eye tracking virtual behaviour monitoring system

Army trainers can also manually alter the robot's mood from a control room if they want to make the scenario more challenging for the soldier.

It is an unprecedented breakthrough in technology for the army, who can now train its soldiers against a 'thinking' enemy. Soldiers are used to training with static wooden targets.

Secret 'Planet 9' Hiding In Our Solar System And Interstellar 'Cigar' On List...

Headlines:

IT is easy to feel like we know nothing about our universe, and unexplained stellar objects are the most puzzling feature of all.

It is easy to blame advanced alien civilizations for causing stars to fade and galaxies to bend, but do these arguments hold any weight?

As it turns out, anything is possible - and despite technological advancements, some mysteries remain unsolved today.

Researchers have uncovered evidence of a hefty planet tracing a bizarre orbit through the outer solar system.

The object, dubbed Planet Nine or Planet X, is around 10 times more massive than Earth and orbits 20 times farther from the Sun than Neptune.

In fact, it would take the planet between 10,000 and 20,000 to complete one full trip around the Sun.

But it is worth noting that Planet Nine's existence was determined existence through mathematical modeling.

A proposal appeared in a 2016 edition of the Astronomical Journal, but the distant object has yet to be observed directly.

However, the two Caltech astronomers who authored the paper believe Planet Nine's presence could explain the behavior of several small objects beyond Neptune.

The weather on the gas giant Ditsö` is literally alien. Clouds of solid quartz appear and disappear thanks to silicon and oxygen atoms continually evaporating from and then condensing in its atmosphere.

Ditsö`, also known as WASP-17 b, orbits a star 1,300 light-years from Earth. One side of the planet is perpetually locked so that it faces the star and is thus permanently illuminated as the dayside. That half of the planet reaches temperatures of 1,773 K (1,500 °C), according to Hannah Wakeford, an astrophysicist at the University of Bristol .

The nanocrystals in Ditsö`'s clouds heat up and break apart as they travel through the dayside but begin to cool down as they approach the planet's darker half. "You've got this tinkling of crystals forming and shrouding the nightside," Wakeford says.

Wakeford knows this as coleader of one of the first teams of scientists to use infrared (IR) spectrometers on board the $10 billion James Webb Space Telescope (JWST) , launched in December 2021. The JWST is the world's latest flagship satellite-based telescope, its spectrometers recording the brightness of IR-wavelength light invisible to human eyes. Scientists want to record light from stars—specifically, the colors whose brightness is reduced when the planets that orbit those stars pass across them. Those dimmer colors have been absorbed by chemicals in the planets' atmospheres.

The researchers can then determine what those chemicals are by interpreting the wavelengths absorbed, giving an unprecedented view of chemistry elsewhere in our galaxy.

The JWST is the largest space telescope ever launched, with a 6.5 m mirror made of 18 hexagonal, gold-coated beryllium sections collecting and focusing light. That's nearly three times as wide as the mirror in its predecessor, the Hubble Space Telescope. The mirror helps make the JWST 100 times as sensitive as Hubble, which allows it to pick up much dimmer light.
