Things are looking up for digging deep on Mars. Progress is palpable on how best to extract subsurface ice to generate drinkable water, rocket fuel and other useful resources on the Red Planet.

But boring down from the topside of Mars to reach available icy reservoirs is no slam dunk.

Tackling that challenge is the company Honeybee Robotics, which calls its approach the RedWater concept.

"RedWater has proven to be the right architecture for deep drilling on Mars," said Kris Zacny, vice president of the exploration technology group at Honeybee Robotics in Altadena, California.

Zacny said that RedWater can serve dual purposes, drilling for scientific exploration and water mining. "It's a win-win. We are at a position where this technology can be infused into [the] next Mars missions," he told Space.com.

Recent revelations about subsurface water ice on the Red Planet mesh well with RedWater.

Over the years, data gathered by Mars orbiters has revealed that a third of the Martian surface contains ice near the surface, as well as more deeply buried ice sheets.

For example, earlier this year, observations by the European Space Agency's Mars Express probe suggested that layers of water ice stretch several miles below ground in some places on the planet.

Adding to the Mars ice story is this month's report at the 55th Lunar and Planetary Science Conference of a previously unseen volcano.

The new research speculates that, beneath that greatly eroded feature, glacier ice is likely still present, preserved near the surface in a relatively warm equatorial region on Mars.

Meanwhile, Honeybee technologists have recently completed end-to-end testing of a RedWater system in the company's cold chamber, said Joey Palmowski, a systems engineer at the company.

That work was undertaken through a NASA Next Space Technologies for Exploration Partnerships (NextSTEP-2) grant, Palmowski told Space.com.

The RedWater system utilizes two proven terrestrial technologies, already put into action in support of polar operations in both Greenland and Antarctica. They are coiled tubing that unspools from the surface into underlying ice, and what's termed the Rodriguez Well, or "RodWell" concept.

RodWell is a method of melting a well in subsurface ice and pumping the liquid water to the surface.

To cut to the chase: Water ice in the form of debris-covered glaciers or ice sheets, perhaps hundreds of meters thick, has been detected and mapped in the mid-latitudes of Mars. That's a favorable spot for a future human expeditionary outpost.

Nathaniel Putzig is associate director and senior scientist at the Planetary Science Institute's office in Lakewood, Colorado.

As co-lead of the Subsurface Water Ice Mapping (SWIM) on Mars project team, Putzig and colleagues are busy charting the location and depth of mid-latitude ice on Mars.

They're now wrapping up a third phase of the SWIM work, which explicitly aimed to help establish targeting priorities for the prospective International Mars Ice Mapper (I-MIM) mission concept.

A radar-carrying orbiter, the I-MIM is a projected NASA undertaking in partnership with the Italian space agency, the Japan Aerospace Exploration Agency (JAXA), and the Canadian Space Agency to develop an ice-scouting Mars orbiter.

I-MIM's key goal is to characterize the extent and volume of water ice in the mid- and low-latitude regions of the planet.

Putzig said he senses that NASA and the other international partners are anxious to pursue the I-MIM mission.

Nevertheless, there has been significant budget uncertainty regarding the endeavor, Putzig observed, certainly on the NASA side and perhaps with other agencies as well.

"This makes it difficult for the international partners to finalize their agreements and begin actively designing and building the mission hardware and instruments," Putzig noted.

There are uncertainties within present-day datasets, Putzig said, so more research and especially new orbital radar sounding capabilities are needed at Mars.

Once in hand, that information can definitively identify and characterize buried ice at landing-site scales for broad regions across the mid-latitudes of Mars, Putzig added.

"That said, one could in principle send landed missions to higher latitudes or to locations where fresh impacts have exposed ice and be assured of encountering ice in the subsurface using a drill without first acquiring that additional data," said Putzig. "However, even for such locations, the lateral and vertical extent and concentration of the ice will remain poorly constrained without new instruments."

Drilling even 1 meter (3.3 feet) into ice can be difficult, explained Isaac Smith, an associate professor at York University in Toronto, Ontario. He's also a senior scientist at the Planetary Science Institute, headquartered in Tucson, Arizona.

Such drilling on Earth requires loads of thermal or electrical power and a lot of human power. "It's especially hard when the ice is much colder than minus 40 degrees Celsius (minus 40 degrees Fahrenheit), like all ice on Mars," Smith said.

That was found to be the case with the NASA Phoenix Mars lander mission in 2008, said Smith. The legged stationary spacecraft plopped down on the planet farther north than any previous mission, at a latitude equivalent to that of northern Alaska, then scooped up Martian soil and checked for and found water ice.

"That ice-cemented soil [at the Phoenix lander locale] is really hard to dig in, but anyone who lives in Canada during winter knows not to go digging in a backyard when the ground is frozen," Smith pointed out.

Carefully sampling any ice on Mars would yield a bonanza of science returns, Smith said.

"Polar ice can give you a detailed record of climate history; mid-latitude ice can become a resource for future space exploration and is the next frontier for seeking life on Mars," Smith advised. "Just as getting rock samples can provide clues to Mars' early history, ice will give us clues to Mars' recent history."

All good news, but reaching depths of tens of meters or more is a big task, Smith said. Doing so is very energy intensive, he said, and requires a lot of human intervention, even on Earth.

"For the foreseeable future, it will have to be done by robots on Mars, probably over long periods, requiring extra levels of robustness, which adds cost, and some power source that we don't have yet," Smith said. "It's feasible in the long term, and Honeybee Robotics is probably the company to build it."

MGM pooh-poohed reports that Mars, 38, was in debt. According to Billboard, the entertainment company said that its relationship with the musician is long-standing and rooted in mutual respect. Back in 2016, Mars announced a long-term deal with MGM, which resulted in his Vegas residency at the Park MGM.

In mid-March, TV network NewsNation published a report claiming that Mars was in US$50 million debt with the company. The story went viral, sparking concern for the beloved musician. In the report, a source was quoted as saying, MGM basically own him, because of the debt he had allegedly racked up.

But MGMs statement clearly explains its partnership with Mars, adding, Together, we are excited to continue creating unforgettable experiences for our guests.

Who is Tori Spellings wealthy mum, Candy and does she help her daughter?

Mars and MGMs partnership has been well documented. His residency, which was supposed to end in August 2023, was extended until September 2024, per Vulture.

Additionally, Mars just opened The Pinky Ring cocktail bar in collaboration with MGM hotel and casino, the Bellagio, in February. According to Las Vegas Weekly, the venue even has some of the singers Grammy awards on display and Mars touch can be traced all over this penthouse-style party pad.

The title of Mars 2016 album 24k Magic was apparently well chosen. With his estimated net worth of US$175 million, according to Celebrity Net Worth, theres no denying that he knows how to make money. He spent much of the following two years touring as part of his sold-out 24k Magic World Tour, which reportedly earned him more than US$237 million, reported Forbes.

In 2021, Billboard reported that Mars was only the second to make over US$50 million from a Park MGM residency. Lady Gagas Enigma residency made US$53.9 million, making it the highest earning residency ever.

It was his upbringing in Hawaii that encouraged him to open a bar, the SelvaRey Rum Bar at the Fairmont Orchid. I grew up in Hawaii, and Ive been performing in Oahu my whole life, he told People magazine. As a young kid, you see all this joy, and when Im performing on stage, everybodys got a beautiful cocktail in their hand. The name of the bar is based on SelvaRey, a rum brand launched in 2014 co-owned by the musician.

Subtle interactions between planetary orbits change Earths climate and geological processes. Scientists have picked up on such a signal in cyclic periods of heavy erosion on the floor of the deep sea.

The study, published in Nature Communications, found that gaps in sedimentation across the globe have occurred in 2.4-million-year cycles, which the authors say can be explained by the interactions of Marss and Earths orbits. The findings have implications for scientists understanding of Earths past and future.

Theres no other way to explain this cyclicity other than this orbital interaction between Earth and Mars.

The discovery came from an analysis of publicly available sedimentation data from the past 50 years of ocean drilling at hundreds of sites worldwide.

When analyzed together, data from 293 deep-sea drill holes showed a pattern: About every 2.4 million years, there was a gap in the sediment record, referred to as a hiatus.Researchers had initially identified the gaps as part of a study published in 2022 but only recently discovered their cyclicity after analyzing the patterns in the sediment record.

The hiatuses are likely a result of vigorous deep-sea currents that swept away sediment on a global scale, said geophysicist Dietmar Mller at the University of Sydney, a co-author on the new study. Overall, the researchers observed 27 cycles in the sedimentation data over the past 70 million years.

Because the pattern was cyclic, the team looked to the solar system for clues. Scientists have known for decades that other planets can influence Earths orbit and, subsequently, Earth systems, thanks to cycles on the order of 10,000100,000 years called Milankovitch cycles.

Longer cycles of millions to tens of millions of years, often called astronomical grand cycles, exist too, though less evidence has been found for them in the geological record.

A 2.4-million-year grand cycle involving the orbit of Mars is the most likely explanation for the patterns seen in the sedimentary data, according to the studys authors. Theres no other way to explain this cyclicity other than this orbital interaction between Earth and Mars, Mller said.

Benjamin Mills, a biogeochemist at the University of Leeds who was not involved in the research, said the data add to the limited records that show astronomical grand cycles affecting Earth.

Mills was part of a team that observed similar 2.4-million-year cycles in ocean oxygen levels and biodiversity. Hes working on new research that links these cycles of biodiversity to orbital changes. There are lots of interesting extensions of the work by Mller and his colleagues, Mills said.

The researchers methods were original, as most work to reveal orbital forcing on Earths paleoclimate is done by looking at sediment itself, rather than gaps in sediment, said Margriet Lantink, a geologist at the University of WisconsinMadison who was not involved in the new research. The data the team used to show the cyclicity are relatively convincing, she said.

The specific interaction the researchers point to involves Earths perihelionthe point in Earths orbit where its closest to the Sun. Every 2.4 million years, Marss orbit pulls Earths perihelion slightly closer to the Sun, increasing the solar radiation that hits Earth.

That extra solar radiation isnt much, but the researchers hypothesized that its enough to kick-start feedback loops on Earth that alter Earths processessuch as ocean currents. Warming spurred by the orbital changes could have led to an increase in cyclone activity that caused more vigorous ocean currents and seafloor erosion, Mller said.

The important thing for the rest of us in the field to do now is to start testing some of these ideas.

Scientists will need to do more work to demonstrate the link between orbitally forced warming and deep-sea currents, Mills said. The studys authors have done a good job in suggesting what might cause the actual hiatuses, but so far its just a suggestion, he said. The actual process of how you get from orbital change to what they see in the sedimentological recordthere could be many steps to that.

The important thing for the rest of us in the field to do now is to start testing some of these ideas, Mills said.

As well as offering an understanding of Earths past, the findings could help predictions of Earths future and, particularly, how Earth systems will respond to warming, Mller said. Humans are contributing to climate change much faster than any geological or astronomical processes, Mller said. But data on Earths past can still inform simulations of future climate effects by allowing scientists to rule out other drivers, such as Milankovitch cycles or astronomical grand cycles, he said.

Ultimately, it helps us differentiate anthropogenic changes to the system from naturally occurring changes, he said.

Mars as a Driver of Deep-Sea Erosion - Eos

Many craters in the mid-latitudes of Mars are partially filled with deposits that have been interpreted to be ice-rich. We expect the deposits to have formed at an earlier (but relatively recent) time when Mars' orbital parameters were different and allowed ice to condense and deposit in these locations. The ice is covered by dust layers protecting it from sublimating away.

The ice deposits are probably no older than a few million years, which is recent in geological terms. However, we can observe that these deposits have been affected by even more recent movement of the crust (the curving trough) that clearly post-dates the ice deposits because it is cutting through them. A wider view allows us to trace this crustal movement or "fault," and we can see it is also affecting the crater wall and the area surrounding it. This observation indicates that Mars' interior is still (or at least until recently was) warm enough to sustain such activity.

Good Ol' Grateful DeadcastLaunches Season 9 Tomorrow, Focusing onFrom The Mars Hotel& Story Behind The Grateful Dead's Famed Wall of Sound

50 years ago, theGrateful Deadwere cooking with gas. It was spring 1974, the band had successfully emerged from a series of hectic, harrowing times, and would soon follow their transformativeWake Of The Floodwith the second acclaimed album release on their very own Grateful Dead Records:From The Mars Hotel. During the mere eight months that had passed between those two beloved LPs, the group also played some of their most exploratory live music and largest venues to date, famously amplified by the homemade, 75-tonWall of Soundthat they debuted on March 23rd, 1974, at their hometown Cow Palace in Daly City, CA. Eternal staples such as "Scarlet Begonias," "Ship Of Fools" and "U.S. Blues" would first be introduced into setlists along that season's tour, before the Grateful Dead spent two months recording and honing them in the studio forFrom The Mars Hotel. Not to mention perennial classics like "China Doll" and "Loose Lucy," or "Pride of Cucamonga" and "Unbroken Chain" the final two tracks Phil Lesh would sing on a Grateful Dead studio album. Now, as Grateful Dead members and tributaries continue to celebrate and bring so many of these formative songs to the masses,From The Mars Hotelhas been remastered and expanded with newly unearthed material and rarities, in honor of its 50th Anniversary.

OutJune 21stvia Rhino, six days before the album's original release on June 27, 1974,From The Mars Hotel (50th Anniversary Deluxe Edition)features remastered audio by GRAMMY Award-winning engineer David Glasser, with Plangent Processes tape restoration and speed correction. Produced for release by Grateful Dead Legacy Manager and Audio Archivist, David Lemieux, the deluxe edition also includes demos of"China Doll"and"Wave That Flag" the song that became "U.S. Blues" as well as a previously unreleased live performance of the Grateful Dead atUniversity of Nevada-Renoon5/12/1974. As the band filled an outdoor football stadium with epic highs like a huge "China Cat Sunflower" > "I Know You Rider,"Mars Hotelcuts including "U.S. Blues" and classics such as "Brown-Eyed Women," "Tennessee Jed," "Mississippi Half-Step," "Truckin'" and "Sugar Magnolia," a massive wind storm was no match for the Wall of Sound. Designed to improve the listening and performance experience at what were becoming larger gigs and longer, more dynamic and varied sets, the Wall of Sound required 21 stage hands, and underlined the resounding effect the Grateful Dead were having on American audiences and culture at the time, even as the entire operation remained homespun and humble.

Pre-orderFrom The Mars Hotel (50th Anniversary Deluxe Edition)on 3CD and digital formats, and hear"Wave That Flag (Demo),"available on DSPs for the first time today

In addition to the50th Anniversary Deluxe Edition,From The Mars Hotel (50th Anniversary Remaster)will be released on June 21st as a single 180-gram black vinyl LP, limited edition Neon Pink vinyl, limited edition "Ugly Rumors" custom vinyl exclusive toDead.net, and a specially-designed picture disc created in partnership with zoetrope pioneerDrew Tetz. When viewed with a camera or strobe, the zoetrope LP will appear to animate, and can be pre-ordered along with the rest ofFrom The Mars Hotel (50th Anniversary Remaster)variantsHERE.

Recorded in San Francisco's Coast Recorders studio,From The Mars Hotelfinds Keith Godchaux particularly shining across a variety of keys, from the "China Doll" harpsichord to the pounding piano on Bob Weir's "Money Money," to the churchy organ that elevates "Ship Of Fools." Lyricist Robert Hunter packs "U.S. Blues" with a barrage of imagery, pop-culture references and sardonic asides as Canadian author Ray Robertson writes in the50th Anniversary Edition's liner notes, it "carries an undeniable whiff of late-capitalism ennuiit's the most fun you'll ever have dancing to the end of the American Empire." Jerry Garcia's jaunty lead guitar drives bouncing melodies across the LP, while guests include Ned Lagin's unnerving synth effects on "Unbroken Chain," Clover member John McFee's country-rock pedal steel on "Pride Of Cucamonga," and more.

From The Mars Hotelpeaked at #16 on the Billboard 200 chart in 1974, contributing to the Grateful Dead's historic achievement last month, when they broke the all-time record forMost Top 40 albums on the Billboard 200.

In tandem with today's announcement, theGood Ol' Grateful Deadcastwill premiere its ninth seasontomorrow, March 28th. Following 5 million downloads and counting, the official Grateful Dead podcast will now unlock the many secrets ofFrom The Mars Hotel. Along with a track-by-track breakdown of the album, this season will tell the story of the game-changing Wall of Sound, with archival audio of its mastermind legendary LSD chemist Owsley Stanley and new interviews with those who made the larger-than-life speaker system a reality.

About the Grateful Dead

The Grateful Dead is a social and musical phenomenon that grew into a genuine American treasure. In 1965, an entire generation was linked together by common ideals, gathering by the hundreds and thousands. This movement created a seamless connection between the band and its fans. As the band toured, Dead Heads would follow. Not because it was a part of popular culture but because it is a true counterculture that exists to this very day-one that earnestly believes in the value of its beliefs. By 1995, the Grateful Dead had attracted the most concertgoers in the history of the music business, and today remains one of the all-time leaders in concert ticket sales. Eventually, the caravan evolved into a community with various artists, craftsmen and entrepreneurs supplying a growing demand for merchandise that connected them to the music. Today, the connection is as strong as ever. The band was inducted into the Rock & Roll Hall of Fame in 1994 and received a GRAMMY Lifetime Achievement Award in 2007. Their final tally of 2,318 total concerts remains a world record. The Grateful Dead recently celebrated their 59th Top 40 album on the Billboard chart, a feat no other group has achieved.

The Province is supporting the preservation of a historic piece of B.C.s aviation history to ensure its story can be shared with residents and visitors for generations to come.

The Hawaii Martin Mars water bomber is a proud symbol of B.C.s ingenuity and innovation, representing cutting-edge technology in aviation firefighting of its time, said Lana Popham, Minister of Tourism, Arts, Culture and Sport. We recognize the value the Hawaii Martin Mars water bomber holds for many people and have heard their desire to have it housed in the British ColumbiaAviation Museum, where it can be displayed and protected as an important piece of our provinces history.

To protect and preserve the Hawaii Martin Mars water bomber as a significant part of B.C.s aviation history, the Province is providing $250,000 in one-time funding to the British ColumbiaAviation Museum to establish the aircraft as the centrepiece of its new B.C. wildfire aviation exhibit. The new exhibit will be interactive, inviting visitors to explore the features of the aircraft up close, and foster an appreciation for its historical, cultural and aeronautical significance. The Hawaii is one of only two Martin Mars water bombers left in existence.

This is great news for people with an interest or who work in the aviation industry, and for B.C.s cultural and tourism sectors, said Bob DEith, Parliamentary Secretary for Arts and Film. Our government is pleased to support this co-operative effort to add this iconic water bomber to British ColumbiaAviation Museums permanent collection, where it is sure to become a part of the signature attractions B.C. has to offer our visitors and residents.

The water bombers final flight from Coulson Aviation Tanker Base in Port Alberni to Victoria International Airport is expected before the end of 2024 and will be a multi-phased process. This includes passing federal inspections, crew training and test flights.

The Hawaii Martin Mars can land and take off only on water. Therefore, its last flight will be from Sproat Lake to the Saanich Inlet beside Victoria International Airport. The final stage will take place on the Canadian Coast Guard Base Patricia Bay, a former seaplane port, where the aircraft will be brought up on a ramp, mounted on a trailer and transported across Victoria International Airport runways.
