Covid-19: Cook Islands records another positive case from New Zealand – Stuff.co.nz

Posted: February 21, 2022 at 6:45 pm

The Cook Islands is reporting a fourth person who has tested positive for Covid-19.

The case is a New Zealand-based Cook Islander who arrived in Rarotonga for a family funeral on February 15 on-board an Air NZ flight.

Health Ministry Te Marae Ora (TMO) confirmed the case tested positive on Thursday from a sibling who had tested positive in New Zealand.

The case went to the airport to be tested with a rapid antigen test (RAT), returning a positive result.

Health officials have advised the case to return to where they were staying at their family home for a 10-day isolation order with their four household contacts.

Four close contacts at the household have been tested with PCR tests, with only the case testing positive.

The positive case and three of the adults are fully vaccinated, with the young contact with their first vaccine dose.

An additional 16 close contacts have been identified, connected through the family funeral the case attended on Wednesday.

Health officials said contact tracing has also identified 18 potential close contacts on the Air NZ flight NZ946, with all of them now quarantining.

Two of the 18 close contacts are quarantining in an island outside of Rarotonga, Aitutaki. They have received negative RAT and PCR tests.

Due to the new positive case, the Cook Islands government has announced an extension to their suspension of passenger travel to the rest of the Pa Enua (other islands) to midnight of February 23.

The government has yet to make a decision on passenger travel to Aitutaki.

Super Rugby talking points: New Zealand sides poised to lead the charge – Stuff.co.nz

Posted: at 6:45 pm

OPINION: If one things clear after the opening round of Super Rugby Pacific, its that the Kiwi teams are almost certainly going to lead the way.

A trans-Tasman clash wasnt even required to paint the picture, rather just a look at the contrasting derby matches on offer to kickoff the competition.

Its no huge surprise, either. Not after Australian sides won just two of 25 matches in Super Rugby Trans-Tasman a year ago, and were on the wrong end of a bunch of lopsided defeats.

Indeed, border issues forcing a diet of derby matches until late April are likely just delaying the inevitable roasting of the Aussie franchises.

They couldnt handle the tempo the New Zealand sides play with last year, and early signs are they wont when they go head-to-head in the second half of the regular season.

The Brumbies last-ditch 29-23 win over the Force in Canberra on Sunday at least featured an entertaining conclusion, but the two other matches across the ditch were forgettable.

Those who watched the Crusaders beat the Hurricanes 42-32 in Dunedin on Saturday, and stayed tuned to their televisions for the dour Reds-Rebels fixture, both deserve a medal and would have noted the gulf in quality.

Crusaders wing Leicester Fainga'anuku celebrates his third try against the Hurricanes in Dunedin on Saturday night.

Admittedly, heavy rain pelted Brisbane for the second half of the match, won 23-5 by the Reds, making for a miserable spectacle, but there was no such excuse earlier in the match.

Plus, a boggy ground in Queenstown, the result of a downpour ahead of kickoff on Saturday, didnt stop the Chiefs and Highlanders playing an up-tempo game of considerably higher quality.

Its only one week, but for the competitions sake, lets hope the Australians get up to speed come April.

Hurricanes No 8 Ardie Savea on the charge against the Crusaders in Dunedin on Saturday night.

Some Hurricanes fans were fuming after their side had three tries disallowed against the Crusaders, but coach Jason Holland was not.

Fair enough, too. Referee Brendon Pickerill and TMO Mike Fraser were bang on each time, including when Fraser spied a Ben May knock-on, which rubbed out a long-range Ardie Savea try.

Savea had earlier been well held up by some desperate goal-line defence, while hooker Asafo Aumua had a try scratched for a double movement.

So obvious was Aumuas infringement, the only complaint anyone should have is Pickerill, who was in perfect position to see the rake's left knee hit the deck metres short of the line, didnt pick up on it in real time.

Holland, having watched his side trail 42-18 with nine minutes to play, before scoring two late tries to add some respectability to the final score, was, rightfully, more peeved with his teams lack of execution.

Chiefs lock Brodie Retallick tackles Highlanders midfielder Scott Gregory in Queenstown on Saturday.

The sight of Brodie Guzzler Retallick making big plays in his first game for the Chiefs since 2019 ought to fill their fan base with confidence.

Retallicks sublime offload to set up Emoni Narawas second half try highlighted the Chiefs 26-16 win against the sloppy Highlanders.

A year after making the Super Rugby Aotaroa final, the Chiefs, armed with Retallick, a healthy Sam Cane, and Josh Ioane at first five-eighth, sure look set to again seriously challenge for the title this year.

As bad as the Highlanders were, they need not panic, nor should any team beaten in round one, not in a competition in which eight of the 12 teams make the playoffs.

The Waratahs celebrate their drought-snapping win against the Fijian Drua in Sydney on Friday.

The Waratahs have done it, theyve finally won a game.

It took a first-up date with newcomers Fijian Drua, but 538 days after their last win, they ended their miserable run with a 40-10 win in the Super Rugby Pacific opener.

Theyll take it, but shouldnt get carried away after winning a match which made it clear just how difficult 2022 will be for the Drua and Moana Pasifika.

Fijian Drua Vilive Miramira carts the ball into contact against the Waratahs in Sydney in the opening Super Rugby Pacific match on Friday.

The inaccurate Drua were comprehensively outplayed by far the worst franchise in 2021, highlighted by their poor handling and a shaky set piece.

Well likely get our first proper look at the latter next weekend, when they play the Chiefs in Dunedin.

Waratahs 40 (Will Harris try 13min, Dave Porecki try 35min, Lalakai Foketi try 41min, Angus Bell try 52min, Jake Gordon try 57min; Ben Donaldson 3 pen, 3 con) Fijian Drua 10 (Nemani Nagusa try 65min; Baden Kerr pen, con). HT: 21-3

Occupiers give Government a filthy PR boost as Labour and National agree on vaccine mandate strategy – Stuff.co.nz

Posted: at 6:45 pm

ANALYSIS: As the anti-mandate crowd continued to mill around Parliament, leaving the national flag strewn on the forecourt, some scumbags threw human waste at the police who had earlier erected barricades limiting the spread of the protest-turned-occupation.

Meanwhile, Prime Minister Jacinda Ardern was inside the Beehive, chairing cabinet, before giving a timeline for the expected peak of Omicron and the relaxing of restrictions something the occupiers all claimed to want.

As with any protest, there are a mixture of passionate, basically ordinary people, there for a good time, and the extreme, deluded or unhinged. And the latter elements have given a PR gift to the Government. After spending two weeks trying to prove that they werent extremists or collection of ferals (to use the words of Speaker Trevor Mallard), some of them literally threw human waste at the cops.

Back in the Beehive Theatrette, there was a reprieve from the ever-present slightly manic and expectant energy outside. The Government expects that the peak of Omicron based on the other countries will be in the next three to six weeks, and after coming off the peak, restrictions including vaccine certificates, mandates and gathering limits will be eased.

Robert Kitchin/Stuff

A police officer looks on at the Parliament occupation where many protesters have discarded their New Zealand flags at the picket line.

READ MORE:* National calls for a phasing out of vaccine requirements, as protests continue* Covid-19 NZ: Jacinda Ardern says mandates will wind down after Omicron peak* When will the Parliament protest, and mandates, end?

The real question that protesters want to know is when. The prime minister wouldn't answer that on the basis that it is still unclear how long it will be until case numbers really come down.

Ardern waited until well into her press conference on Monday to really hit upon the key point that this whole exercise the vaccine mandates, vaccine certificates, contact tracing has really all been to prepare New Zealand for this point.

In answering a question about whether Omicron was more serious than the flu, the prime minister pointed out that the problem is not the population-wide severity, it is people getting it all at once.

I think the issue is that Covid is in a pandemic state ... so that's where the real issue lies, making sure that you're able to properly manage that, because if you're overwhelmed, people who otherwise might be able to be cared for properly through treatment miss out on that because of the pressure in the system, she said.

ROBERT KITCHIN/Stuff

Prime Minister Jacinda Ardern and Deputy Prime Minister Grant Robertson hold a post-cabinet press conference in the Beehive at Parliament.

Going back to the start of 2020 when Covid-19 first arrived in New Zealand, this was always the crux of the policy problem. How do you slow the spread so that hospitals aren't overwhelmed? Elimination stopped New Zealand from having to confront that problem for nearly two years.

About half an hour before the press conference, National Party leader Christopher Luxon gave his own speech in which he called for almost exactly the same thing the prime minister announced.

As with the Prime Minister, he declined to put an exact timeframe on when this should happen, but that it should be done progressively.

Abigail Dougherty/Stuff

National leader Chris Luxon tried to emphasis a division within New Zealand during his speech on Monday.

It was part of a speech trying to point to New Zealand as divided and sheeting that division home to Labour but over various issues.

Renters versus landlords. Business owners versus workers. Farmers versus cities. Kiwis at home versus those stuck abroad. The vaccinated versus the unvaccinated, Luxon said.

In essence, Luxon was trying to use the occupation as a way of mounting a broader critique. The problem is that on the issue du jour the protests he holds virtually the same public view that the Prime Minister does.

That is, National is a pro-vaccination Party, it also doesn't believe in engaging with lawbreaking protesters and thinks vaccine mandates should be scrapped after the Omicron peak.

The fact remains that a very healthy majority of the country opposes the protests, and in a political sense, polling is pretty much business-as-usual, with Labour ahead right now. There isnt much that points to a deeper and broader division beyond the usual left-right divide.

Up to, now it's all gone the protesters way: growth in numbers, some sympathy for the cause and building a little community. Now that the barricades have started to be erected, and the reality of maintaining the occupations momentum and numbers will set in.

‘In principle’ agreement to resettle 150 refugees a year in NZ hailed as ‘historical moment’ – 9News

Posted: at 6:45 pm

Refugee advocates have hailed news of an "in principle" agreement to resettle 150 refugees a year in New Zealand from Australia's offshore detention regime.

Refugee Mostafa "Moz" Azimitabar, who spent six years in detention at Melbourne's The Park Hotel, called the update, which emerged from Senate estimates on Monday night, a "historical moment".

The New Zealand offer, which has been on the table for several years, has been subject to multiple rounds of ministerial negotiations as Australia seeks to ensure refugees won't have access to a so-called "backdoor" to eventually live in Australia.

Department of Home Affairs deputy secretary of strategy and resilience Marc Ablong told Monday night's Legal and Constitutional Affairs Committee Senate estimates hearing that the final round of talks was just weeks away "on the New Zealand side".

"They have to take the matter to their cabinet, so it'll have to go through the New Zealand cabinet process before they come to us with their final position," he said, before adding that both governments would be considering the matter at "roughly the same time".

Department of Home Affairs Secretary Michael Pezzullo said it was "fair to say" an in principle agreement had been reached.

"The Australian government has made it clear, subject to the satisfaction of both parties and the resolution of a number of issues," he said, in response to a question from Victorian Labor Senator Raff Ciccone.

Mr Pezzullo echoed concerns previously raised by Home Affairs Minister Karen Andrews and other Morrison government ministers that settling in New Zealand could provide a "backdoor" into Australia through a special-purpose visa allowing "long-duration residency".

"There has to be, to satisfy the Australian government's policy, some kind of ironclad or, if not quite ironclad, firm blocking," he said.

The department secretary said the Australian government was looking for an "early resolution" to the matter but refused to define a timeframe.

"We would be reluctant to say 'this year', because I think we've said that before, and that was last year," he said.

"The power of people is stronger than politicians. The government couldn't resist this powerful pressure," he said, according to Amnesty International.

"Our consistency made this happen."

Positive cases in New Zealand King Salmon processing plant – Stuff.co.nz

Posted: at 6:45 pm

Staff in a processing plant at New Zealand King Salmon are using rapid antigen tests after positive cases of Omicron in the factory, director general of health Dr Ashley Bloomfield says.

On Wednesday, 15 new Covid-19 cases were reported in Te Tauihu (the top of the south).

In its daily update, the Ministry of Health announced a further 1160 cases nationally.

Bloomfield said New Zealand King Salmon in Nelson was continuing to operate despite cases in a processing plant, in keeping with the countrys shift to phase two of the response.

Scott Hammond/Stuff

The Nelson plant will continue to operate, with workers using rapid antigen tests.

All had Rapid Antigen Tests and theyre going to be using the RATs to allow them to keep operating.

Under phase two, critical workers exposed to the virus can continue working while using RATs to test for the virus.

It comes after nine cases were announced in Nelson-Marlborough on Tuesday, and as three schools in Nelson Victory Primary School, St Josephs Primary School and Nayland College have all had cases, forcing close-contact students and staff to isolate.

There had also been positive presentations at the Nelson Hospital emergency department.

Anyone with symptoms is being urged to get a test.

The Nelson Marlborough community did a fantastic job in Phase One of stamping out Omicron, said Nelson Marlborough Healths medical officer of health Dr Stephen Bridgman.

This delayed the spread of infection in the community meaning more people were able to get boosted and prepared.

We know that we cannot stop Omicron. The escalation of cases in Nelson over the past two days shows how quickly it can spread and how disruptive it can be to workplaces and schools. It also shows how prepared education and workplaces are in supporting employees, students and communities through Omicron.

On Wednesday the country moved to phase two in the Omicron response plan.

That means that isolation periods have reduced to 10 days for positive cases and household contacts, and seven days for close contacts.

Under phase two, isolation periods for people with Covid will reduce to 10 days, while isolation for close contracts will drop to seven days.

Contact tracing will also change, with positive cases required to fill out an online form to identify high-risk exposure events.

New Zealand King Salmon sustainability and stakeholder manager Paul McIntyre said staff who had tested positive had been on the night shift on Monday.

Of those who tested positive, there were 66 close contacts, all who were self-isolating at home.

Previously, Bloomfield had said there were 250 close contacts at New Zealand King Salmon.

McIntyre said all relevant staff had been tested, and all staff in the processing plant had access to RAT kits.

Nelson Zealand King Salmon had been designated a critical business by the Government, which allowed double-vaccinated asymptomatic close contacts to return to work following a negative RAT test.

Staff would be paid sick-leave if they tested positive for Covid-19 if they had sick-leave available.

Our policy is that anyone who is awaiting a PCR test are to self-isolate until the results of the test is known.

Exports to China had been stopped as soon as they knew about the cases. Otherwise they were supplying to all other markets.

McIntyre said their primary concern was to keep team members safe in this emerging situation.

We are working closely with the NMDHB and Ministry of Health to ensure the correct protocols and processes are being followed to avoid any spread in the community.

Perseverance Mars rover marks a year on red planet – New York Post

Posted: at 6:42 pm

Friday, February 18th marked the first anniversary ofNASAsPerseverance roversMarslanding.

The rover first touched down in the planets Jezero Crater on Feb. 18, 2021.

The Mars 2020 missionlaunchedJuly 30, 2020, from the Cape Canaveral Space Force Station in Florida.

Since then, NASAs Jet Propulsion Laboratory (JPL)noted in a statement, it has racked up a series of accomplishments, including new distance records.

The2,263-pound robotic geologistcollected the first rock core samples from anotherplanet, tested the first prototype oxygen generator on Mars and deployed Ingenuity, the first robotic helicopter to take off on another planet.

According to the agency, Percy also recently broke a record for the most distance driven by a Mars rover in a single day, traveling almost 1,050 feet using its AutoNav software on Feb. 14.

Perseverance which carried the most cameras ever sent to Mars has nearly wrapped up its firstsciencecampaign in the crater, which contained a lake billions of years ago.

It is currently gathering rock cores from the crater floor the first step in theMars Sample Return campaign.

Two more samples will be collected in the coming weeks that scientists believe could provide an age range for Jezeros formation and lake.

The samples Perseverance has been collecting will provide a key chronology for the formation of Jezero Crater, Thomas Zurbuchen, associate administrator of NASAs Science Mission Directorate, said in a statement. Each one is carefully considered for its scientific value.

Perseverances journey has run into a couple of snags thus far.

Itsfirst attemptat drilling a rock core was unsuccessful and somepebbleshindered progress last month.

In subsequent missions in cooperation with ESA (European Space Agency), NASA would send spacecraft to Mars to collect the sealed samples and return them to Earth.

A key objective for the Perseverance mission is astrobiology and the hunt for signs of ancient microbial life.

Incredible NASA Mars Images Show Clouds Passing Across Martian Sky – Newsweek

Posted: at 6:42 pm

Clouds can be seen passing through the Martian sky in new images taken by NASA's Curiosity rover.

Curiosity is one of NASA's Mars exploration vehicles which has been on the planet's surface since August 2012. It is the predecessor to the newer Perseverance rover which touched down on Mars almost exactly one year ago in February, 2021.

While Perseverance may be more technically advanced, Curiosity is still operating to this day, and is conducting valuable research on the Red Planet.

Last week, NASA released new images from Curiosity that were taken in mid-December last year at a time when the rover was more than 3,300 Martian days into its ongoing mission.

The images, taken using Curiosity's navigation camera, are snapshots of Mars' clouds. Taken some time apart, the images have been stitched together to form two eight-frame videos.

Taken from two different perspectives, one of the videos shows the clouds passing directly overhead while the other shows the clouds passing over the landscape.

They can be seen below.

The presence of clouds on Mars does not mean liquid water, however. By comparing the two perspectives, scientists were able to calculate that the clouds were around 50 miles high and were probably made out of carbon dioxide ice due to the extremely low temperatures at that altitude.

Scientists should also be able to calculate how fast the clouds are moving, though NASA did not disclose a figure.

Mars is a cold, inhospitable planet with an average temperature of around -81 degrees Fahrenheit, and an atmosphere largely composed of carbon dioxide with some water vapor.

It's not the first time that Curiosity has photographed clouds on Mars. In May 2021, NASA released images of "shining clouds" taken by the rover in March of that year.

The space agency described the Martian clouds as "wispy puffs filled with ice crystals that scattered light from the setting Sun, some of them shimmering with color."

By studying images of Mars' clouds, scientists can understand how they form on Mars and why some are different to others.

NASA's Mars rovers have a habit of exceeding their initial planned operation times. Curiosity's primary mission was due to last just 23 months, but the rover continues to work nearly a decade later.

While this is no doubt an impressive feat of endurance, Curiosity is yet to surpass the marathon efforts of the Opportunity rover, which was designed to last just 90 Martian days and travel around 3,300 feet after landing on Mars in 2004.

But Opportunity just kept on going and its mission was finally declared over in February 2019 after failing to communicate with Earth following a severe dust storm.

By this time the rover had surpassed all expectations, surviving for more than 60 times its life expectancy and travelling more than 28 miles.

NASA and HeroX are Crowdsourcing the Search for Life on Mars – Universe Today

Posted: at 6:42 pm

For almost sixty years, robotic missions have been exploring the surface of Mars in search of potential evidence of life. More robotic missions will join in this search in the next fifteen years, the first sample return from Mars (courtesy of the Perseverance rover) will arrive here at Earth, and crewed missions will be sent there. Like their predecessors, these missions will rely on mass spectrometry to analyze samples of the Martian sands to look for potential signs of past life.

Given how much data we can expect from these missions, NASA is looking for new methods to analyze geological samples. To this end, NASA has partnered with the global crowdsourcing platform HeroX and the data-science company DrivenData to launch the Mars Spectrometry: Detect Evidence for Past Life challenge. With a prize purse of $30,000, this Challenge seeks innovative methods that rely on machine learning to automatically analyze Martian geological samples for potential signs of past life.

Despite sixty years of concerted efforts by multiple space agencies, the search for life on Mars has yielded little more than inconclusive results (as demonstrated by the Viking 1 and 2 landers). Nevertheless, modern surveys have found that Mars was a much warmer and wetter place billions of years ago. This discovery is one of the most profound breakthroughs in planetary science and has led to renewed efforts to find evidence of past (and maybe even present) life on Mars.

During the Noachian Period (ca. 4.1 to 3.5 billion years ago), Mars had a denser atmosphere, and surface conditions were warm enough that liquid water flowed on its surface. Evidence of this is preserved today in the form of river channels, sedimentary deposits, delta fans, and other features known to form in the presence of flowing water. By knowing how long these conditions persisted, scientists hope to determine how long life could have existed.

Unfortunately, conducting chemical analysis on soil and rock samples is time-consuming work. Moreover, analyses can suffer from false positives when they are strictly reliant on human interpretation. By leveraging machine-learning techniques, where analytical models are created from huge datasets, scientists hope to automate the chemical analysis process, making it more efficient and less time-consuming.

For this Challenge, NASA is looking innovative methods to automatically analyze data obtained by the Sample Analysis at Mars (SAM) instrument aboard the Curiosity rover. This data is provided by the NASA Goddard Space Flight Center (GSFC) and Johnson Space Center (JSC), and the SAM science team. For years, Curiosity has used the SAM instrument to gather Martian soil and rock samples and subject them to evolved gas analysis (EGA).

This consists of heating samples until they emit gases that can be analyzed by spectrometers for specific chemical signatures. The SAM instrument accomplishes this with a gas chromatograph that separates gases to aid in identifying them, a mass spectrometer that detects elements necessary for life, and a tunable laser spectronometer that detects water vapor and analyzes methane to see if it is biotic in origin (produced by living things).

As Greg Lipstein, the Principal of DrivenData, said in the Challenge press release:

This is a fascinating research question where machine learning tools can have a real impact on how we can learn more about our place in the universe. Its a great chance to harness the collective intelligence and passion of the data community to advance the state of open science.

According to the Challenge page, the best methods should be able to detect certain families of chemical compounds that are of interest to astrobiologists. These include nitrogen, phosphorous, sulfur, oxygen, and carbon, the chemical building blocks of life, and volatiles such as water, ammonia, and methane, which are associated with biological processes. Competitors will also be able to advantage of the many experimental runs done on analog samples.

From this, competitors are tasked with developing machine learning methods that will support scientists in analyzing and interpreting data collected by missions (in-situ samples) and laboratory instruments (from sample-return missions). It is also hoped that these advancements will help scientists conduct future mission operations with greater speed and efficiency. The competition launched on February 18th and will remain open to submissions until April 18th, 2022.

The winning techniques will receive $15,000 (first place), $7,500 (second), $5,000 (third), with a bonus prize of $2,500. In addition, the winning entries may be used to help analyze data from Mars and potentially even inform future instruments conducting in-situ analysis. This includes the ESA-Roscosmos ExoMars 2022 mission, consisting of the Russian Kazachok lander, the ESA Rosalind Franklin rover, and NASAs Dragonfly mission to Titan (Saturns largest moon).

Its exciting to think there might be clues of past life on Mars, said HeroX CEO Kal K. Sahota. These challenges are so inspiring as we search for evidence of extraterrestrial life.

The Challenge is open to anyone aged 18 or older, and participants may compete as individuals or as a team. The competition is open to individuals and teams from anywhere in the world, provided federal sanctions do not prohibit participation (some additional restrictions may apply).

The Devils in the Detail: Fascinating and Otherworldly Landscape on Mars – SciTechDaily

Landscape near Hooke Crater in Mars southern highlands captured by the CaSSIS camera onboard the ExoMars Trace Gas Orbiter (TGO) on February 1, 2021. Credit: ESA/Roscosmos/CaSSIS, CC BY-SA 3.0 IGO

Chaotic mounds, wind-sculpted ripples and dust devil tracks: this image shows a fascinating and otherworldly landscape near Hooke Crater in Mars southern highlands.

The image was taken by the CaSSIS camera onboard the ESA/Roscosmos ExoMars Trace Gas Orbiter (TGO) on February 1, 2021, and shows part of Argyre Planitia, centered at 46.2S/318.3E.

This type of scenery is similar to chaotic terrain: a kind of broken, disrupted terrain seen across Mars where haphazard groups of variously sized and shaped rocks irregular knobs, conical mounds, ridges, flat-topped hills known as mesas clump together, often enclosed within depressions. There are around 30 regions of chaotic terrain defined on Mars (see ESA Mars Express views of Ariadnes Colles, Pyrrhae Regio, and Iani Chaos for just a small sample); while this small patch has not been defined as one of these, its appearance is certainly chaotic.

Perhaps the most striking feature here is the wispy, snaking tendrils stretching out across the frame. These dark traces of past activity were caused by dust devils, whirlwinds of dust that occur on both Mars and Earth when warm air rises quickly into cooler air. These devils leave tracks on a planets surface as they travel through dusty landscapes. The tracks here appear to have a north-south orientation, indicating a possible local wind pattern.

The bluish tinge to the dust devil tracks seen here is a result of the three filters that were combined to create this image; while not representative of what an observer would see with the naked eye, these filters produce a color infrared image with greater sensitivity to variations in surface mineralogy.

TGO arrived at Mars in 2016 and began its full science mission in 2018. The spacecraft is not only returning spectacular images like this one, but also providing the best ever inventory of the planets atmospheric gases, and mapping the planets surface for water-rich locations. It will also provide data relay services for the second ExoMars mission, comprising the Rosalind Franklin rover and Kazachok platform, when it arrives on Mars in 2023.

Earth to Mars in just 45 days: New tech promises shorter trip to red planet – WION

Posted: at 6:42 pm

Yes, you read that correctly.

It is now possible to reach Marsin as little as 45 days, which is nothing short of a science enthusiast's dream.

According to Canadian engineers, a laser-based technology for reaching Mars might drastically reduce the time it takes to reach the Red Planet.

At current rates, it would take around 500 days for a person to reach Mars, according to NASA projections.

However, engineers at McGill University in Canada claim to have created a "laser-thermal propulsion" technology that employs lasers to heat hydrogen fuel and claims to decrease journey time by half to 45 days.

The US space agency wants to send a crew to Mars in the mid-to-late 2030s, around the same time China plans to place humans on the Red Planet.

Watch: One year since Perseverance rover landed on Mars

It's called "directed-energy propulsion" because it uses enormous lasers shot from Earth to transmit power to photovoltaic panels aboard a spacecraft, which generate electricity and thrust.

While near Earth, the spacecraft accelerates rapidly, then races toward Mars during the next month, releasing the main vehicle to land on Mars and returning the rest to Earth to be recycled for the next launch.

Reaching Mars in six weeks was previously thought to be conceivable only with nuclear-powered rockets, which pose greater radiation hazards.
