NASA’s little Mars helicopter aced its second test flight Thursday, soaring even higher and longer than before.
The 4-pound (1.8-kilogram) chopper, named Ingenuity, hovered longer and also flew side to side this time, according to NASA's Jet Propulsion Laboratory in California. It achieved the intended altitude of 16 feet (5 meters) and even accelerated sideways 7 feet (2 meters).
This hop lasted 52 seconds, 13 seconds longer than the first one.
“Go big or go home!” JPL tweeted in announcing the Earth Day news.
The success came just three days after Ingenuity made the first powered flight by an aircraft on another planet. The helicopter carried a bit of wing fabric from the Wright Flyer that made similar history at Kitty Hawk, North Carolina, in 1903.
Flight controllers had to wait four hours before learning Thursday's outcome. Like it did during Monday's 10-foot-high (3-meter-high) hop, the helicopter sent back a black and white photo showing its shadow against the dusty, rock-strewn surface now known as Wright Brothers Field.
“It sounds simple, but there are many unknowns regarding how to fly a helicopter on Mars," Ingenuity’s chief pilot, Havard Grip, said from JPL in a statement. “That’s why we’re here — to make these unknowns known.”
One of the challenges is the planet’s extremely thin atmosphere — 1% that of Earth's.
NASA plans up to three more test flights in the next 1 1/2 weeks, venturing higher each time with more complicated acrobatics. Ingenuity hitched a ride to Mars on the rover Perseverance, which photographed the proceedings from more than 200 feet (64 meters) away. The rover team allotted one month for the $85 million tech demo; The clock started ticking when Ingenuity was released from Perseverance's belly on April 3.
“We have two flights of Mars under our belts, which means that there is still a lot to learn during this month of Ingenuity," chief engineer Bob Balaram said in a statement.
Perseverance and Ingenuity arrived at Mars in mid-February, landing in an ancient river delta following a 6 1/2-month flight.
Once Ingenuity's flights are complete, Perseverance will set off on its journey to find any signs of past microscopic life. A robotic geologist, the rover will collect core samples of the most enticing rocks and set them aside for pickup by a future spacecraft a decade from now.
In another first, an experiment on the rover successfully converted Mars’ carbon-dioxide-rich atmosphere into pure oxygen this week. Five grams of oxygen was produced, according to NASA, the equivalent of 10 minutes of breathing for an astronaut. Large-scale production at Mars could yield oxygen not only for air, but also rocket fuel. More tests are planned over the next two years.

Amazon is betting that ammonia could be the fuel of the future, participating in a Series A round for the Brooklyn-based company Amogy in December. Amogy aims to de-carbonize transportation with a clean energy system that uses ammonia as a renewable fuel. Amogy is partnering with Amazon on its first commercial product - an ammonia-powered cargo-shipping vessel. Amogy CEO Seonghoon Woo joins Cheddar Climate to discuss.
Cryptocurrency is expected to become a part of our daily lives — but what sort of environmental impact does it have? As the U.S. becomes the crypto mining capital of the world, climate advocates are worried about mining companies reopening old coal plants, using massive amounts of energy, wasteful hardware, and more. Congressional Democrats led by Senator Elizabeth Warren are demanding answers from mining firms about their electricity use and waste levels. John Belizaire, CEO of Soluna Computing, joins Cheddar Climate to discuss the congressional letters, how crypto mining can become a green industry, and more.
Driver assistance monitoring systems are meant to keep the driver's eyes on the road, but according to a report from AAA, different ways of monitoring provide significantly different results. The study found that direct camera-based systems that scanned the driver's eye movements were faster and more reliable than those indirect systems that looked at steering-wheel input. Megan McKernan, the manager of automotive services for the Automobile Club of Southern California, joined Cheddar to discuss the findings. "Triple-A is recommending that automakers include both direct and indirect systems just to really prevent consumers from trying to misuse these systems," she said, noting that neither system on its own is not foolproof.
Wave Neuroscience is a neurological health tech company that specializes in clinical and at-home personalized brain stimulation technology. Erik Won, president and chief medical officer and Fred Walke, CEO, joined Cheddar's Opening Bell to discuss their company's hopes for allowing patients to identify and treat unique brain disorders while empowering them to understand their unique neurological makeups — including for the high-stress positions of professional athletes. "We have a mobile device that provides a very light stimulation that gives them a therapy that gives them confidence so there's a just knowing that they're doing something for it," said Walke. "But it also helps them get back into a rhythm. It helps their brain synchronize around certain frequencies that that we target, and it helps them really understand that they've done everything they can to get to their highest level of success."
Democratic lawmakers are now calling on Bitcoin mining companies in the U.S. to assess how much electricity they use and how it could all potentially impact residents and the environment in the near future. Since its conception, crypto mining has been at the center of a debate. The question is: Is crypto mining playing a key role in renewable energy or could it totally derail U.S. climate goals? Host of The Wendy O show Wendy O, joined Cheddar to discuss more.
Nutritional supplement beverage company Athletic Greens has achieved unicorn status. The company announced a new $115 million funding round, bringing its valuation to $1.2 billion. The company's flagship product AG1 combines 75 different vitamins, minerals, and other nutrients into one daily serving.
