NASA Ingenuity: Meet the woman launching a helicopter on Mars

What does it take to build a helicopter to fly on Mars? 

For starters, you can forget the remote control. Mars is more than 30 million miles away on a good day, so the time delay in sending and receiving signals means you couldn’t fly the spacecraft with a joystick — you have to send waypoints in advance from here on Earth and hope for the best. 

It also needs to charge itself. And it has to be able to take off in the incredibly thin Martian atmosphere (roughly 100 times thinner than Earth’s atmosphere), meaning the entire helicopter — including solar panel, batteries, computers, rotors and landing gear — has to weigh less than 4 pounds. And how do you test it in a simulated Martian environment? Well, you’re going to have to design that process from scratch as well. 

It might sound like an impossible task, but that’s

NASA technology to reveal crop health insights for agriculture industry

A Georgia-based company called Cybercorps LLC plans to offer real-time agricultural data for farmers, resource managers, first responders, and other interested user groups with the help of a patented NASA technology. Cybercorps has signed a license agreement with NASA for the Compact Thermal Imager (CTI), a technology developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The technology, conceived at Goddard by CTI Principal Investigator Murzy Jhabvala, is small enough to fit on a cube satellite, or CubeSat, a type of miniaturized satellite whose size is measured in units of 10 square centimeters that plays a growing role at NASA for science missions and technology demonstrations. Though tiny in size, CTI can provide high-resolution information about crop health and soil conditions by measuring surface temperature. After collecting more than 15 million images of Earth during a successful demonstration on the International Space Station in 2019, the instrument is now

Infrared NASA imagery finds Chan-hom organizing, consolidating

Infrared NASA imagery finds Chan-hom organizing, consolidating
On Oct. 6 at 0353 UTC (Oct. 5 at 11:53 p.m. EDT) NASA’s Aqua satellite analyzed Tropical Storm Chan-hom using the Atmospheric Infrared Sounder or AIRS instrument. AIRS found coldest cloud top temperatures as cold as or colder than (purple) minus 63 degrees Fahrenheit (minus 53 degrees Celsius) around the consolidating center.

NASA’s Aqua satellite analyzed the large Tropical Storm Chan-hom as it tracked through the Northwestern Pacific Ocean. Aqua imagery showed the storm was consolidating, indicating a strengthening trend.

One of the ways NASA researches tropical cyclones is using infrared data that provides temperature information. The AIRS instrument aboard NASA’s Aqua satellite captured a look at those temperatures in Chan-hom and gave insight into the size of the storm and its rainfall potential.

Cloud top temperatures provide information to forecasters about where the strongest storms are located within a tropical cyclone. The stronger the storms,

NASA Mars probes discover billion-year-old dune fields frozen in time

The HiRise camera on the Mars Reconnaissance Orbiter snapped these dune fields in Valles Marineris. They’re estimated to be a billion years old

NASA/JPL/University of Arizona

Mars has a roughly 4.5-billion-year history. Thanks to our robotic explorers, we have a good sense of its current climate and atmosphere. A new study of ancient sand dunes points to what it might have been like a billion years ago on the red planet. 

A team led by Planetary Science Institute (PSI) research scientist Matthew Chojnacki took a close look a wind-driven dune fields in Valles Marineris, an area of Mars known for its extensive canyons. The dunes appear to have been preserved through lithification, a geologic process that turns sediments into rock.

The team published a study on this window into the martian past in the journal

  • NASA has partnered with a company that specializes in 3D printed homes and other structures to come up with a way to print structures on the lunar surface.
  • NASA’s Artemis missions will send humans to the Moon, but in the distant future NASA wants a more permanent presence of humans on the Moon.
  • The company is reportedly being paid $14 million as part of the deal.

NASA wants to send humans back to the Moon sooner rather than later, and while those early crewed missions will be more about getting there, conducting research, and leaving, the U.S. space agency envisions a future where more permanent settlements on the lunar surface are possible. To that end, NASA has penned a deal with a company called ICON to develop technology that would allow for easy construction on the Moon.

ICON is best known for its 3D

NASA Images Reveal Potential for ‘Mega Tsunami’ in Alaska

NASA has released satellite images showing an unstable mountain slope in Alaska experts warn could trigger a devastating “mega-tsunami.”

The mountain slope is located above a fiord called Barry Arm on Alaska’s south coast, which lies around 60 miles east of Anchorage.

The slope is partially supported by the Barry Glacier, but this body of ice has retreated significantly over the past decade. As a result, the slope is becoming more unstable, a team of 14 scientists said in an open letter published in May this year on the website of the Alaska Department of Natural Resources, Division of Geological and Geophysical Survey.

The retreat of the glacier is creating the perfect conditions for the slope—which is moving slowly downhill—to collapse suddenly, causing a rapidly-moving landslide with the potential to produce a massive tsunami wave reaching hundreds of feet in elevation along the shores of Barry Arm and the adjacent

NASA infrared imagery reveals wind shear displacing Marie’s strongest storms

NASA infrared imagery reveals wind shear displacing Marie's strongest storms
On Oct.5 at 6:20 a.m. EDT (1020 UTC), the MODIS instrument that flies aboard NASA’s Aqua satellite gathered infrared data on Marie that confirmed wind shear was adversely affecting the storm. Persistent westerly vertical wind shear showed strongest storms (yellow) pushed east of the center where cloud top temperatures were as cold as minus 50 degrees Fahrenheit (minus 45.5 Celsius). Credit: NASA/NRL

NASA’s Aqua satellite provided an infrared view of Tropical Storm Marie that revealed the effects of outside winds battering the storm.

Wind shear occurs when winds at different levels of the atmosphere push against the rotating cylinder of winds, weakening the rotation by pushing it apart at different levels.

NASA’s Aqua Satellite Reveals Effects of Wind Shear 

Infrared light is a tool used to analyze the strength of storms in tropical cyclones by providing temperature information about a system’s clouds. The strongest thunderstorms that reach highest into the

NASA imagery reveals Tropical Storm Chan-hom’s skewed structure

NASA imagery reveals Tropical Storm Chan-hom's skewed structure
On Oct. 5, 2020, NASA’s Terra satellite provided a visible image of Tropical Storm Chan-hom several hundred miles northwest of Guam (lower right). Credit: NASA Worldview, Earth Observing System Data and Information System (EOSDIS).

NASA’s Terra satellite obtained visible imagery of Tropical Storm Chan-hom as it continued moving though the Northwestern Pacific Ocean. The imagery revealed that the center of circulation was exposed and its strongest storms were south of the center.

Tropical Depression 16W formed on Oct. 4 and strengthened into a tropical storm on Oct 5. Once it reached tropical storm strength, it was re-named Chan-hom. Laos submitted the name Chan-hom to the World Meteorological Organization list. The name is a type of tree in Laos.

Nasa captures an exploding supernova on camera

To enjoy the CBBC Newsround website at its best you will need to have JavaScript turned on.

Take a look at this brilliant video from Nasa which shows the star exploding!

Nasa has captured an exploding supernova on camera.

The supernova called SN 2018gv is located around 70 million light-years away from Earth, in the spiral galaxy NGC 2525.

A supernova is a pretty spectacular cosmic event, which happens when a star reaches the end of its life cycle and collapses in on itself.

This causes an incredibly powerful explosion which can send shockwaves across the galaxy, and can even create black holes.

According to Nasa, supernova SN 2018gv unleashed a surge of energy that was five billion suns brighter than our Sun. That’s pretty bright!

The scientists were able to record the exploding star using the Hubble Space Telescope.

A series of 208 images captured by NASA’s Transiting Exoplanet Survey Satellite (TESS) over one year reveal a dazzling sea of stars and 74 exoplanets in the northern sky, the space agency said in a release Monday. TESS has now imaged around 75% of the sky over two years. The planet-hunter wrapped up its second year of science operations in July. 

Astronomers are looking through another 1,200 exoplanet candidates to confirm whether new worlds exist there. More than half of those candidates are in the northern sky, NASA says.

TESS pinpoints planets by monitoring several stars simultaneously over large chunks of the sky and keeping watch for any
