It was up, up, and away last weekend for NASA's Ingenuity helicopter, which completed its 24th Martian flight on Sunday (April 3).

The sortie was just a short repositioning hop, covering 154 feet (47 meters) of ground in 69.5 seconds at a maximum altitude of 33 feet (10 m). But it was an important flight, helping reposition Ingenuity for its exit out of the Stah region of Mars' Jezero Crater on its way to an ancient river delta, where the helicopter will work in tandem with NASA's life-hunting, sample-collecting Perseverance rover.

Sunday's flight also marked the first time the helicopter took off at a different time of day 9:30 a.m. local mean solar time (LMST), rather than the standard 10 a.m. LMST.

Since March 10, Ingenuity has been making its way across Stah, a region filled with hazards for little helicopters namely rock- and dune-filled terrain that could cause the vehicle to flip upon landing. (Perseverance, on the other hand, is taking a roundabout route to avoid the uneven Mars terrain.)

The first three Stah flights went off without a hitch, but Ingenuity's team faced a tough decision for the final leg of the journey, with three options that each presented challenges. The team ultimately chose a flight plan that included the tiny hop completed on Sunday, which put Ingenuity in an opportune position for the final flight out of Stah, mission team members explained in a blog post on Tuesday (April 5).

That flight plan, however, required Ingenuity to fly 30 minutes earlier in the day than usual on Sunday. Because the helicopter uses its solar-powered batteries to heat itself at night, it "wakes up" with some battery depletion, which it replaces when the sun rises in the morning. Taking off earlier in the day means that Ingenuity has less time to recharge before a flight, adding to the risk.

But Ingenuity demonstrated the capability to fly earlier on Flight 24, so the helicopter is currently preparing for its exit out of Stah;the flight instructions have already been uplinked to Mars.

Ingenuity is proving to be the little engine that could, vastly exceeding its original mission a five-flight technology demonstration designed to show that it's possible for a helicopter to explore Mars. Since its first flight on April 19, 2021, Ingenuity has flown 23 more times, covering a total distance of 3.21 miles (5.17 kilometers).

Martian weather is awfully dusty.

A camera aboard NASA's Mars Curiosity rover a car-sized robot that's explored the planet for nearly a decade recently spotted a dusty wind gust blowing over the red desert.

You can see the weather in the footage below, which was captured by one of the machine's Hazard-Avoidance Cameras, or Hazcams. The top image shows the Hazcam footage, while the bottom shows frames processed (with "change detection software") to help visualize how the gust moved.

Mars rovers have snapped dust devils churning across the desert before. But NASA researchers think this latest burst of dust is a windy gust. "Scientists believe it's a wind gust rather than a dust devil since it doesn't appear to have the trademark vorticity, or twisting, of a dust devil," NASA explained.

Sometimes, Mars experiences extreme, long-lived dusty weather events, like dust storms. These storms can be huge, but they're also normal. "Every year there are some moderately big dust storms that pop up on Mars and they cover continent-sized areas and last for weeks at a time," explained Michael Smith, a planetary scientist at NASAs Goddard Space Flight Center.

And around every five years or so, a truly monstrous dust storm can encompass much of the planet.

In this dusty world, the Curiosity rover continues to gradually climb a region called Mount Sharp, which is a peak inside Mars' Gale crater. The NASA robot seeks to determine if the planet could have ever been habitable enough for tiny microbes to thrive, perhaps in the moist soils of lakebeds or streams.

So far, there's no evidence of life existing anywhere beyond our extremely biodiverse planet, Earth.

Look up at the sky before sunrise Saturday (April 9) to see a trio of planets, twin stars and the moon entering its next phase.

The planets Venus, Mars and Saturn appear close together in the southeast predawn sky. Saturn moved steadily toward Mars, reaching its closest proximity on Tuesday, April 5, when the planets were only half a degree apart. While the three worlds still appear close to one another, Saturn is slowly moving away from Mars each day, according to a statement from NASA (opens in new tab).

Venus can also be seen to the lower left of Saturn and Mars, rising about 10 degrees above the southeastern horizon before sunrise. You'll need to get up early to see the three planets align.

There's even more to see in the twilight sky on Saturday. In addition to the planetary trio, the stars Castor and Pollux shine bright in the constellation Gemini the Twins. The stars appear to the lower right of the moon, which reaches its first quarter phase.

Castor and Pollux are the two brightest stars in the constellation, representing the heads of the twins with fainter stars outlining the pair's bodies. Pollux is a red giant star located 33 light-years from Earth, while Castor is actually made up of six stars, located about 51 light-years away.

Skywatchers can use the moon as a reference point to spot the twin stars, as the moon passes near Castor and Pollux on April 8 and 9, according to EarthSky.org (opens in new tab).

Reaching its first quarter stage on April 9, the moon will appear prominent in the evening sky. It will be visible starting around 7:47 p.m. EDT (2347 GMT) and set in the middle of the night. Skywatchers will have the best viewing opportunity shortly after sunset, as dusk fades to darkness.

The moon will rise 69 degrees above the south-western horizon, appearing almost exactly half illuminated. It will dip below the horizon by 3:06 a.m. EDT (0706 GMT). However, the moon will stick around longer in the night sky over the next few days, setting later each day, according to In-The-Sky.org (opens in new tab).

Adelaide's River Torrens has, in recent years, earned a reputation for being about as friendly to animal lifeas the planet Mars is suitable for human living.

But the Torrens or, at least, an aquatic plant that iscommonly found on its surface has been recruited for a study into how humans could one day live long and prosper upon the red planet.

Duckweed, also known as water lentil, isbeing touted not only as a partialsolution tothe problem of getting to Mars, but also to the problem of how humans survive there.

"People often mistake it for an algae, and think maybe it's an algal bloom on the water but actually it's more closely related to land plants like wheat and barley," bio-scientist Jenny Mortimer told ABC Radio Adelaide's Stacey Lee and Nikolai Beilharz.

"Rowing clubs are a bit annoyed by it, having to paddle through it, but actually it's a perfectly normal thing, it doesn't release any toxins so it's not dangerous at all."

Associate Professor Mortimer is running a project with PhD students at the University of Adelaide looking at duckweed's many potent properties, and its suitability as a form of sustenance forhuman life and basis of future civilisation.

"If humans want to do long-term space exploration so going beyond the space station, but [also] maybe living on the surface of the Moon or even going to Mars then one of the biggest problems is food, because you just simply can't take everything you need with you," Associate Professor Mortimer said.

"We've done some calculations and if you send a crew of four people to Mars, it's about a three-year round trip, that's 10 tonnes of food and that doesn't even [take] into account trying to make sure the food is nutritiously stable across those three years.

"One solution is that maybe you want to grow some of the food as you go with you, but trying to do that in a small, confined space on a space shuttle is quite challenging so we're looking to different alternatives and duckweed is one of those."

While duckweed may not necessarily conform witheveryone's idea of what's appetising, it is eaten by humans in parts of the world, including south-east Asia.

Dr Mortimer said it has much to recommend it not only is it high in protein and nutrients, it grows fast and tends to take on the taste of whatever environment it has been exposed to, which can be both a blessing and a curse.

"It tends to pick up the flavour of whatever it's been growing in," Associate Professor Mortimer said.

"Someone else who works in the US, he's put a little bit of bacon flavouring in and it took up the bacon flavour."

But Associate Professor Mortimersaid there was no way anyone should be eating it from the Torrens, which has battled pollution in recent decades.

"You can actually [eat it] as it is.I mean, not directly out of the Torrens I don't know what else is in there," she said.

"One of the things we're doing in my group is collecting different Australian strains to compare how they behave and grow."

When scientists talk about making it to Mars, they tend to focus on the logistics of the journey.

Elon Musk once joked that he wanted "to die on Mars just not on impact".

But just as big a challenge as the landingis the aftermath and Professor Mortimer said duckweed could be part of the solution to the question of setting up a colony.

"We're also looking at a way of making other things out of it," she said.

"I'm really interested in using it as a system, so a little green photosynthetic reactor for making other molecules you might need in remote environments or on a space flight, so whether that's pharmaceuticals or even perhaps some types of building material."

While she conceded its use in actual space missions might be decades away, Associate Professor Mortimer said it could help with a more rarefied culinary problem.

Duckweed's capacity to absorb other flavours could again prove useful to counteringmenu fatigue on space missions and preventingweight loss, albeit inzero gravity.

"If astronauts lose weight, it's a huge problem because they are really sort of meant to be performing at the top of their game," she said.

"NASA and this is the same in the military and all sorts of other places they develop these highly crafted menus that are the right amount, of calories for these elite athletes who are astronauts, but people just get bored of eating the same old dehydrated microwave food.

"Sometimes you want something that's fresh or spicy or has crunch one of the most requested up in the space station, when they're allowed to get things from home, is apples because it has that crunch and freshness."

Prince Andrew is asked to understand the trouble his presence at Queen's Platinum Jubilee celebrations can cause for the royal family.

Chairman of Reputation Management Consultants, Eric Schiffer, is urging the Duke of York to not crave for the limelight and tread carefully.

He told Express.co.uk: The odds of seeing Prince Andrew at the Jubilee are the same as Martians landing on the Mall to honour Her Majesty.

Prince Andrew earlier sparked public fury in a failed attempt to make social media comeback via ex-wife Sarah Ferguson's Instagram handle.

The Duke commented on Falkland wars after hijacking Fergie's social media and declared that he is a 'changed man' months after settling out of court for his sexual assault scandal.

US Weekly hosts Christina Garibaldi and Christine Ross dubbed the attempt 'very cringey.'

"He could not read the room on how people are feeling about him right now," they noted.

Mr Garibaldi said: "He really just needs to kind of remove himself from the situation."

Ms Ross then added: "He needs to lay low and take a step back.

A source told The Sun on Sunday newspaper: He was meant to stay invisible during the Platinum Jubilee so there is no way he will be at events like Trooping the Colour.

But the Queen needs a chaperone on all occasions at the moment due to her mobility issues and Andrew has earmarked the Derby as the one he will accompany her at. He just doesnt seem to understand the public outcry.

Last weekend, the Duke came under further scrutiny after a series of posts were shared on his behalf on his ex-wife Sarah Fergusons Instagram account.

Mars is all set to transit in the sign of Aquarius on April 7, 2022, at 14:24. The red planet will remain here till May 17. Aquarius is ruled by Saturn and Mars shares a neutral relationship with the dark planet. Mars is considered as an Army commander and an executor, and its placement in Aquarius continues to demonstrate its leadership skills and dominant qualities. On a personal level, Mars' transit through Aquarius may generate discontent or resentment toward our intimate connections. Our relationships require increased attention to ensure that we remain connected and satisfied with our loved ones. On the career front, one needs to regain energy, refocus on goals, and make additional attempts to progress. Let us consider the effect of this transit on various zodiac signs:

You'll need to exercise patience if you don't want to establish a habit of getting into arguments with your co-workers. An investment could pay off financially for you. Any pending payment will be released. Your spouses behaviour can be a bit unpredictable.

Virgo: Regardless of the situation, you will maintain your passion and vigour. Your superiors will be delighted to see how dedicated and focused you are towards your work. Financially, you'll have to be patient and need to wait for the profits to come in the future. If there is a pending court case, the outcome could be favourable to you. The health of your spouse may be an issue.

In personal relationships, all is well. There's a possibility of celebrating a family function.

Capricorn: In your family, you may have to deal with mental stress. Your words may also contain some bitterness and wrath, which might cause you some difficulty. This behaviour should be avoided at all costs. To some extent, you can build some financial riches if you do thorough study and make wise investments. Avoid driving rashly as there's a risk of injury.

Aquarius: You may notice a shift in your demeanour, with a sudden burst of irritability and stubbornness. You'll do well at work, and you'll finish all of your chores ahead of schedule. You should avoid making any decisions in a rush and refrain from initiating any new ventures. Your expenses may rise. Control your emotions and maintain your composure for harmony in personal life.

Pisces: Your adversaries and rivals will do everything they can to put you under stress and damage your reputation. You may become irritated and acquire a tendency to be jealous of others. If you're attempting to make ends meet, be prepared for a flurry of financial obligations and challenges. Your family life can be in disarray, and you may not be content with your personal relationships.
