NASA's Perseverance rover captured the humming sounds of the tiny Ingenuity helicopter flying above the Martian surface. Why it matters: By recording sound on Mars, scientists will be able to learn more about how the Martian atmosphere works and potentially diagnose problems with Perseverance, should they pop up.Get market news worthy of your time with Axios Markets. Subscribe for free.Driving the news: NASA released a video Friday showing Ingenuity's fourth flight on April 30 when the helicopter flew a 872-foot round-trip test. Perseverance recorded the flight, capturing the Martian wind and hum of the helicopter's blades spinning at 2,537 rpm. (If you're watching the full video, it helps to use headphones.)"We had carried out tests and simulations that told us the microphone would barely pick up the sounds of the helicopter, as the Mars atmosphere damps the sound propagation strongly," David Mimoun, the science lead for Perseverance's SuperCam Mars microphone, said in a statement. "We have been lucky to register the helicopter at such a distance."The big picture: Ingenuity is the first human-made drone to ever fly on another planet, and NASA hopes the tests it's running with the 4-pound helicopter will pave the way for future missions using other drones on Mars and elsewhere. What's next: NASA will continue to test Ingenuity on Mars, allowing it to go on farther flights and one-way trips, potentially to help scout out areas of interest for Perseverance.

Archaeologists discovered the remains of nine Neanderthals at a prehistoric site near Rome, Italy's Culture ministry said on Saturday. The find occurred in Grotta Guattari, prehistoric caves discovered more than 80 years ago, located around 100 metres from the coast of Tyrrhenian Sea in San Felice Circeo, near Latina, in the Lazio region. Neanderthals, the closest ancient relatives of humans, died out about 40,000 years ago.
NASA's Mars helicopter has already completed four flights on the Red Planet. According to the Ingenuity team, it's completed everything it needs to in order to be considered a success, but it's not done yet. In fact, the limits that NASA thought it would have to deal with during the helicopter's testing don't appear to be that big of a deal anymore, and that's great news for the scientists that want to push the helicopter to its absolute limits. In a new blog post on NASA's Mars science website, Josh Ravich of the Ingenuity team at NASA's Jet Propulsion Laboratory reveals the group's feelings about the helicopter's performance thus far. To put it simply, the helicopter has totally crushed it, and the tiny chopper appears to be dealing with all of the hazards of the Martian surface easily. The group had feared that the helicopter might suffer breakdowns early on, but that never happened, and it's performing so well that the Ingenuity team is pivoting to a longer testing timeline. It's actually pretty wild that the helicopter is performing as well as it is. The chopper was built by NASA but it features a number of "off the shelf" parts that weren't designed for Mars. Despite that, the helicopter has stood up well and successfully completed the tasks that its handlers have set forth for it. "Our helicopter is even more robust than we had hoped," Ravich explains. "The power system that we fretted over for years is providing more than enough energy to keep our heaters going at night and to fly during the day. The off-the-shelf components for our guidance and navigation systems are also doing great, as is our rotor system. You name it, and it’s doing just fine or better." The helicopter's fifth flight will be, in many ways, its most important so far. It will fly farther than it ever has and it won't be returning back to its initial landing zone. Instead, it will travel toward a new "airfield" to continue its testing while also remaining within sight of the Perseverance rover. "We are traveling to a new base because this is the direction Perseverance is going, and if we want to continue to demonstrate what can be done from an aerial perspective, we have to go where the rover goes," Ravich said. NASA will continue to push the limits of the helicopter and conduct test flights while they gather more and more data about its flights on Mars. Knowing that Mars didn't completely destroy the helicopter's more sensitive components after it was released by the rover is great news for NASA going forward, and could open the door to more advanced aerial machines to be sent to Mars in the near future.
SpaceX is fresh off a high for its Starship spacecraft development program, but according to CEO Elon Musk, it's already looking ahead to potentially repeating its latest success with an unplanned early reusability experiment. Earlier this week, SpaceX flew the SN15 (i.e. 15th prototype) of its Starship from its development site near Brownsville, Texas, and succeeded in landing it upright for the first time.

Potatoes and lettuce will have to be replaced in the UK by small, mustardy root vegetables and dandelion leaves as a warming climate means we cannot rely on traditional crops, Kew Gardens has said. Horticulturalists and scientists at the gardens are working to see which food plants can be grown to resist increasing pests and diseases, sunnier summers and warmer, wetter winters. Next week, a new TV show exploring the secrets of the gardens will launch on Channel 5, showing how gardeners and scientists worked together during lockdown. Helena Dove, who runs the Kitchen Garden at the facility, grows crops selected by scientists to see how they fare in a British garden plot. She said that potato blight, a disease which can wipe out the whole crop, is becoming more common because of a warmer climate in this country. At some point it may become unviable to grow them, she and other horticulturists and scientists at Kew believe. "Traditional potatoes are becoming very hard to grow because of blight," she said. Two strange-looking, knobbly little roots are being trialed instead, as they fare better in a warm climate and are resistant to blight. The gardener explained: "We have been trying to grow root vegetables that could be substituted in the future. One we grow is oculus tuberosa, and tropaeolum tuberosum - the former is a little lemony root, it does really well, we are breeding it in the UK to make it more suitable for our climate. We also have a mustardy root crop, and sweet potatoes are doing well as well. They could be a replacement. We won’t know for tens of years but we have to start somewhere." Many who tried to grow lettuces during last year's heatwave will have noticed it was an uphill battle. These hot summers are becoming more common, so Ms Dove is working to find hardier alternatives to the salad crop. She said: "Lettuces bolt when it gets hot so we may not be able to grow them in hot dry summers. We are growing tropical leaves, orache, tree spinach, they are traditionally grown for their grain but the leaves are edible so they sort of replace spinach. We are also growing dandelion which have really bitter but delicious leaves. They will keep growing through anything. We are trialling all this for salad in the kitchen garden." Another new way of gardening she is experimenting with is container planting, for those who do not have vegetable patches but want to grow their own food. In the kitchen garden, she is growing a new breed of butternut squash which can fit in a pot, and a mini peach tree which will produce a handful of fruits each year. Ms Dove explained: "The windowsill crops and container planting are a real trend at the moment - we are developing butternut squashes you can grow in a pot - usually they need a lot of room but these work in a pot. "We are in conversation with people to get smaller cultivars to try to get crops that often need a lot of space. I am trialling dwarf peaches and dwarf nectarines that can be grown in a pot. I have this beautiful little tree that will give me 10 peaches this year. People are realising they don’t need a big space to grow something.

Tracking radars are following closely the gradual fall to Earth of a large Chinese rocket vehicle.

Chinese officials promise a rocket that's falling toward Earth probably won't cause any harm. Chinese Foreign Ministry spokesman Wang Wenbin said Friday officials are "closely observing" the Long March 5B rocket booster that's expected to re-enter the Earth's atmosphere this weekend, The Washington Post reports. Part of the Chinese rocket is "tumbling out of control in orbit" following a launch, The New York Times writes, but researchers are still not completely sure where the debris will land. "This is standard international practice," Wang said Friday, per the Post. "The probability of causing harm to aviation activities and the ground is extremely low." Wang also said that most of the rocket's components will burn up during re-entry. The U.S. Air Force Space Track Project on Friday projected debris will crash in a desert outside of Mary, Turkmenistan — but researchers also warned that "the projected site could be wildly off-base," the Post writes. "Its exact entry point into the Earth's atmosphere cannot be pinpointed until within hours of its re-entry which is expected around May 8," U.S. Space Command says. NPR reports that scientists agree it's "unlikely" the booster "will actually hit someone," while adding that this still "doesn't mean there's no risk for humans." The Times may have put it best by writing, "You are almost certainly not going to be hit by a 10-story, 23-ton piece of a rocket hurtling back to Earth. That said, the chances are not zero." Previously, debris from a Long March 5B rocket landed in Africa in 2020, leading NASA to criticize China. "It was seemingly a successful launch, until we started getting information about a re-entry of a rocket body, a re-entry that was really dangerous," then-NASA administrator Jim Bridenstine said. "It flew over population centers and it re-entered Earth's atmosphere. It could have been extremely dangerous. We're really fortunate in the sense that it doesn't appear to have hurt anybody."

NASA’s new administrator is big on tackling climate and diversifying the agency's workforce, but hedging on whether the U.S. can put astronauts on the moon by 2024. In his first interview since becoming NASA’s top official this week, former Sen. Bill Nelson told The Associated Press on Friday that tracking climate change is a top issue. For landing astronauts on the moon, Nelson said the goal remains 2024, a deadline set by the Trump administration.
Astronaut Tracy Caldwell Dyson on the International Space Station with a view many more are likely to see soon. NASA/Tracy Caldwell Dyson/WIkimediaCommonsFor most people, getting to the stars is nothing more than a dream. But on May 5, 2021, the 60th anniversary of the first suborbital flight, that dream became a little bit more achievable. The space company Blue Origin announced that it would start selling tickets for suborbital flights to the edge of space. The first flight is scheduled for July 20, and Jeff Bezos’ company is auctioning off one single ticket to the highest bidder. But whoever places the winning bid won’t be the first tourist in space. On April 28, 2001, Dennis Tito, a wealthy businessman, paid US$20 million for a seat on a Russian Soyuz spacecraft to be the first tourist to visit the International Space Station. Only seven civilians have followed suit in the 20 years since, but that number is poised to double in the next 12 months alone. NASA has long been hesitant to play host to space tourists, so Russia – looking for sources of money post-Cold War in the 1990s and 2000s – has been the only option available to those looking for this kind of extreme adventure. However, it seems the rise of private space companies is going to make it easier for regular people to experience space. From my perspective as a space policy analyst, recent announcements from companies like Blue Origin and SpaceX are the opening of an era in which more people can experience space. Hoping to build a future for humanity in space, these companies are seeking to use space tourism as a way to demonstrate both the safety and reliability of space travel to the general public. Dennis Tito, on the left beside two Russian astronauts, was the first private citizen to ever go to space – and he spent more than a week on the International Space Station. NASA/WikimediaCommons The development of space tourism Flights to space like Dennis Tito’s are expensive for a reason. A rocket must burn a lot of costly fuel to travel high and fast enough to enter Earth’s orbit. Another cheaper possibility is a suborbital launch, with the rocket going high enough to reach the edge of space and coming right back down. This is the kind of flight that Blue Origin is now offering. While passengers on a suborbital trip experience weightlessness and incredible views, these launches are more accessible. The difficulty and expense of either option has meant that, traditionally, only nation-states have been able to explore space. This began to change in the 1990s as a series of entrepreneurs entered the space arena. Three companies led by billionaire CEOs have emerged as the major players: Blue Origin, SpaceX and Virgin Galactic. Though none have taken paying, private customers to space, all anticipate doing so in the very near future. British billionaire Richard Branson has built his brand on not just business but also his love of adventure. In pursuing space tourism, Branson has brought both of those to bear. He established Virgin Galactic after buying SpaceShipOne – a company that won the Ansari X-Prize by building the first reusable spaceship. Since then, Virgin Galactic has sought to design, build and fly a larger SpaceShipTwo that can carry up to six passengers in a suborbital flight. The VSS Unity spacecraft is one of the ships that Virgin Galactic plans to use for space tours. AP Photo/Matt Hartman The going has been harder than anticipated. While Branson predicted opening the business to tourists in 2009, Virgin Galactic has encountered some significant hurdles – including the death of a pilot in a crash in 2014. After the crash, engineers found significant problems with the design of the vehicle, which required modifications. Elon Musk and Jeff Bezos, respective leaders of SpaceX and Blue Origin, began their own ventures in the early 2000s. Musk, fearing that a catastrophe of some sort could leave Earth uninhabitable, was frustrated at the lack of progress in making humanity a multiplanetary species. He founded SpaceX in 2002 with the goal of first developing reusable launch technology to decrease the cost of getting to space. Since then, SpaceX has found success with its Falcon 9 rocket and Dragon spacecraft. SpaceX’s ultimate goal is human settlement of Mars; sending paying customers to space is an intermediate step. Musk says he hopes to show that space travel can be done easily and that tourism might provide a revenue stream to support development of the larger, Mars-focused Starship system. Bezos, inspired by the vision of physicist Gerard O’Neill, wants to expand humanity and industry not to Mars but to space itself. Blue Origin, established in 2004, has proceeded slowly and quietly in also developing reusable rockets. Its New Shepard rocket, first successfully flown in 2015, will be the spaceship taking tourists on suborbital trips to the edge of space this July. For Bezos, these launches represent an effort at making space travel routine, reliable and accessible as a first step to enabling further space exploration. SpaceX has already started selling tickets to the public and has future plans to use its Starship rocket, a prototype of which is seen here, to send people to Mars. Jared Krahn/WikimediaCommons, CC BY-SA Outlook for the future Blue Origin is not the only company offering passengers the opportunity to go into space and orbit the Earth. SpaceX currently has two tourist launches planned. The first is scheduled for as early as September 2021, funded by billionaire businessman Jared Isaacman. The other trip, planned for 2022, is being organized by Axiom Space. These trips will be costly for wannabe space travelers, at $55 million for the flight and a stay on the International Space Station. The high cost has led some to warn that space tourism – and private access to space more broadly – might reinforce inequality between rich and poor. The first tourist to fly on a privately owned spaceship will ride in Blue Origin’s New Shepard Crew Capsule, seen here after a test flight in Texas. NASA Flight Opportunities/WikimediaCommons While Blue Origin is already accepting bids for a seat on the first launch, it has not yet announced the cost of a ticket for future trips. Passengers will also need to meet several physical qualifications, including weighing 110 to 223 pounds (50 to 101 kg) and measuring between 5 feet and 6 feet, 4 inches (1.5 to 1.9 meters) in height. Virgin Galactic, which continues to test SpaceShipTwo, has no specific timetable, but its tickets are expected to be priced from $200,000 to $250,000. Though these prices are high, it is worth considering that Dennis Tito’s $20 million ticket in 2001 could potentially pay for 100 flights on Blue Origin soon. The experience of viewing the Earth from space, though, may prove to be priceless for a whole new generation of space explorers.
