What Do *you* Think Is Inside A Black Hole? Or If They Sun Was A Black Hole What Would We See In The

Five Technologies Taking Aeronautics into the Future

Martian helicopters? Electric planes? Quiet supersonic flight?

The flight technologies of tomorrow are today’s reality at NASA. We’re developing a number of innovations that promise to change the landscape (skyscape?) of aviation. Here are five incredible aeronautic technologies currently in development:

 1. The X-59 QueSST and Quiet Supersonic Technology

It might sound like an oxymoron, but ‘quiet boom’ technology is all the rage with our Aeronautics Mission Directorate. The X-59 QueSST is an experimental supersonic jet that hopes to reduce the sound of a supersonic boom to a gentle thump. We will gauge public reaction to this ‘sonic thump,’ evaluating its potential impact if brought into wider use. Ultimately, if the commercial sector incorporates this technology, the return of supersonic passenger flight may become a reality!

 2. The X-57 Electric Plane

Electric cars? Pfft. We’re working on an electric PLANE. Modified from an existing general aviation aircraft, the X-57 will be an all-electric X-plane, demonstrating a leap-forward in green aviation. The plane seeks to reach a goal of zero carbon emissions in flight, running on batteries fed by renewable energy sources!

3. Second-Generation Search and Rescue Beacons

Our Search and Rescue office develops technologies for distress beacons and the space systems that locate them. Their new constellation of medium-Earth orbit instruments can detect a distress call near-instantaneously, and their second-generation beacons, hitting shelves soon, are an order of magnitude more accurate than the previous generation!

(The Search and Rescue office also recently debuted a coloring book that doesn’t save lives but will keep your crayon game strong.)

4. Earth from the Air

Earth science? We got it.

We don’t just use satellite technology to monitor our changing planet. We have a number of missions that monitor Earth’s systems from land, sea and air. In the sky, we use flying laboratories to assess things like air pollution, greenhouse gasses, smoke from wildfires and so much more. Our planet may be changing, but we have you covered.

5. Icing Research

No. Not that icing.

Much better.

Though we at NASA are big fans of cake frosting, that’s not the icing we’re researching. Ice that forms on a plane mid-flight can disrupt the airflow around the plane and inside the engine, increasing drag, reducing lift and even causing loss of power. Ice can also harm a number of other things important to a safe flight. We’re developing tools and methods for evaluating and simulating the growth of ice on aircraft. This will help aid in designing future aircraft that are more resilient to icing, making aviation safer.

There you have it, five technologies taking aeronautics into the future, safely down to the ground and even to other planets! To stay up to date on the latest and greatest in science and technology, check out our website: www.nasa.gov.

AI, Cancer Therapy and Chemical Gardens Headed to Space Station

A new batch of science is headed to the International Space Station aboard the SpaceX Dragon on the company’s 15th mission for commercial resupply services. The spacecraft will deliver science that studies the use of artificial intelligence, plant water use all over the planet, gut health in space, more efficient drug development and the formation of inorganic structures without the influence of Earth’s gravity. 

Take a look at five investigations headed to space on the latest SpaceX resupply:

Spaceflight has an on impact many bodily systems. Rodent Research-7 takes a look at how the microgravity environment of space affects the community of microoganisms in the gastrointestinal tract, or microbiota.

The study also evaluates relationships between system changes, such as sleep-wake cycle disruption, and imbalance of microbial populations, to identify contributing factors and supporting development of countermeasures to protect astronaut health during long-term missions, as well as to improve the treatment of gastrointestinal, immune, metabolic and sleep disorders on Earth.

Cardiovascular diseases and cancer are the leading causes of death in developed countries. Angiex Cancer Therapy examines whether microgravity-cultured endothelial cells represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels.

Results may create a model system for designing safer drugs, targeting the vasculature of cancer tumors and helping pharmaceutical companies design safer vascular-targeted drugs.

Chemical Gardens are structures that grow during the interaction of metal salt solutions with silicates, carbonates or other selected anions. Their growth characteristics and attractive final shapes form from a complex interplay between reaction-diffusion processes and self-organization.

On Earth, gravity-induced flow due to buoyancy differences between the reactants complicates our understanding of the physics behind these chemical gardens. Conducting this experiment in a microgravity environment ensures diffusion-controlled growth and allows researchers a better assessment of initiation and evolution of these structures.

These investigations join hundreds of others currently happening aboard the orbiting laboratory.

Two Steps Forward in the Search for Life on Mars

We haven’t found aliens but we are a little further along in our search for life on Mars thanks to two recent discoveries from our Curiosity Rover.

We detected organic molecules at the harsh surface of Mars! And what’s important about this is we now have a lot more certainty that there’s organic molecules preserved at the surface of Mars. We didn’t know that before.

One of the discoveries is we found organic molecules just beneath the surface of Mars in 3 billion-year-old sedimentary rocks.

Second, we’ve found seasonal variations in methane levels in the atmosphere over 3 Mars years (nearly 6 Earth years). These two discoveries increase the chances that the record of habitability and potential life has been preserved on the Red Planet despite extremely harsh conditions on the surface.

Both discoveries were made by our chem lab that rides aboard the Curiosity rover on Mars.

Here’s an image from when we installed the SAM lab on the rover. SAM stands for “Sample Analysis at Mars” and SAM did two things on Mars for this discovery.

One - it tested Martian rocks. After the arm selects a sample of pulverized rock, it heats up that sample and sends that gas into the chamber, where the electron stream breaks up the chemicals so they can be analyzed.

What SAM found are fragments of large organic molecules preserved in ancient rocks which we think come from the bottom of an ancient Martian lake. These organic molecules are made up of carbon and hydrogen, and can include other elements like nitrogen and oxygen. That’s a possible indicator of ancient life…although non-biological processes can make organic molecules, too.

The other action SAM did was ‘sniff’ the air.

When it did that, it detected methane in the air. And for the first time, we saw a repeatable pattern of methane in the Martian atmosphere. The methane peaked in the warm, summer months, and then dropped in the cooler, winter months.

On Earth, 90 percent of methane is produced by biology, so we have to consider the possibility that Martian methane could be produced by life under the surface. But it also could be produced by non-biological sources. Right now, we don’t know, so we need to keep studying the Mars!

One of our upcoming Martian missions is the InSight lander. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the "inner space" of Mars: its crust, mantle, and core.

Finding methane in the atmosphere and ancient carbon preserved on the surface gives scientists confidence that our Mars 2020 rover and ESA’s (European Space Agency's) ExoMars rover will find even more organics, both on the surface and in the shallow subsurface.

Solar System: Things to Know This Week

This week, we celebrate the fifth anniversary of the moment our Mars Science Laboratory mission landed the Curiosity rover in Gale Crater. 

In fact, this summer brings several red letter days in Red Planet exploration. Here are 10 things to know about the anniversary of the Curiosity landing—plus some other arrivals at Mars you may not know about.

This self-portrait of NASA's Curiosity Mars rover shows the vehicle at a drilled sample site called "Okoruso," on the "Naukluft Plateau" of lower Mount Sharp. The scene combines multiple images taken with the rover's Mars Hand Lens Imager (MAHLI) on May 11, 2016. Credit: NASA/JPL-CALTECH/MSSS

1. Seven Minutes of Terror 

For Curiosity, landing on Mars meant slowing from about 13,000 MPH (21,000 KPH) to a full stop in just seven minutes. Engineers came up with an innovative--and bold--plan to make this happen, but no one could be 100% certain it would work. In this video, some of the Curiosity engineers who designed the entry, descent and landing system for the mission talk candidly about the challenges of Curiosity's final moments before touchdown in August 2012.

2. Sweet Success 

Relive the tension, and the celebration, of the night Curiosity landed on Mars. You can also simulate the entire landing process in 3-D on your own computer using NASA's free Eyes on the Solar System app.

3. Echoes of Ancient Waters 

What has Curiosity discovered during its roving so far? The key takeaway: the stark deserts of Gale Crater were once home to lakes and streams of liquid water, a place where life could potentially have thrived. Learn more about the mission's scientific findings.

4. Pretty as a Postcard

Sometimes science can be beautiful, as pictures from Mars prove. You can peruse some of Curiosity's best shots. What's more, you can see the very latest images—often on the same day they're downlinked from Mars.

5. Take It for a Spin

Have you ever wanted to try driving a Mars rover yourself? You can (virtually anyway). Try the Experience Curiosity app right in your web browser.

6. Mars Trekking 

Maybe someday you'll be able to take a day hike across the Martian landscape. You can at least plan your route right now, using NASA's Mars Trek site. This interactive mapping tool lets you explore important Red Planet locations using actual terrain imagery from orbiting satellites. You can even retrace the real locations on Mars where the fictional astronaut Mark Watney traveled in "The Martian."

7. A First Time for Everything

Curiosity stands (well, rolls) on the shoulders of giants. Several NASA missions blazed the trail for the current crop of robotic explorers. The first was Mariner 4, which is also celebrating an anniversary this summer. Mariner 4 was the first spacecraft to return photos of another planet from deep space when it flew by Mars on July 15, 1965. Mariner engineers were so impatient to see the first pictures it sent back, that they hand-colored a printout of raw numeric data sent by the spacecraft, in order to construct one of the first color images of Mars.

8. Pathfinders and Panoramas 

Another important pathfinder on Mars was...Mars Pathfinder. This mission just marked its 20th anniversary. To commemorate the first successful Mars rover, NASA created a new 360-degree VR panorama of its landing site you can view right in your browser.

9. One Small Step for a Robot

The first spacecraft to make a successful landing on Mars was Viking 1, which touched down in the Chryse Planitia region on July 20, 1976. It worked for more than six years, performing the first Martian soil analysis using its robotic arm and an onbaord biological laboratory. While it found no conclusive evidence of life, Viking 1 did help us understand Mars as a planet with volcanic soil, a thin, dry carbon dioxide atmosphere and striking evidence for ancient river beds and vast flooding.

10. Mars Explorers Needed 

There is much more to come. The next Mars lander, InSight, is slated for launch next year. Ride along with NASA's ongoing adventures on the Red Planet at: mars.nasa.gov/mars-exploration/

Solar System: Things to Know This Week

For the first time in almost a decade, we're going back to Jupiter. Our Juno spacecraft arrives at the king of planets on the fourth of July. From a unique polar orbit, Juno will repeatedly dive between the planet and its intense belts of charged particle radiation. Juno's primary goal is to improve our understanding of Jupiter's formation and evolution, which will help us understand the history of our own solar system and provide new insight into how other planetary systems form.

In anticipation, here are a few things you need to know about the Juno mission and the mysterious world it will explore:

1. This is the Big One

The most massive planet in our solar system, with dozens of moons and an enormous magnetic field, Jupiter rules over a kind of miniature solar system.

2. Origin Story

Why study Jupiter in the first place? How does the planet fit into the solar system as a whole? What is it hiding? How will Juno unlock its secrets? A series of brief videos tells the stories of Jupiter and Juno. Watch them HERE.

3. Eyes on Juno

If you really want a hands-on understanding of Juno's flight through the Jupiter system, there's no better tool than the "Eyes on Juno" online simulation. It uses data from the mission to let you realistically see and interact with the spacecraft and its trajectory—in 3D and across both time and space.

4. You’re on JunoCam!

Did you know that you don't have to work for NASA to contribute to the Juno mission? Amateur astronomers and space enthusiasts everywhere are invited to help with JunoCam, the mission's color camera. You can upload your own images of Jupiter, comment on others' images, and vote on which pictures JunoCam will take when it reaches the Jovian system.
