Ever Get A Random Craving For A Food When In Space?

What do you hope to find using this new technology? When you were a kid, did you ever dream of landing on Mars? Even if you may not be visiting, tech that you have sway over is.

“When you wer a kid, did you ever dream of landing on Mars?”

Here’s What You Need to Know About Near-Earth Objects

Our solar system is littered with asteroids and comets, and sometimes they get a little close to Earth. But no need to worry! This happens all the time. When an asteroid or comet could come close to our planet, it’s known as a near-Earth object – aka NEO.

But how close is “close”?

A near-Earth object is defined as an object that could pass by our Earth within 30 million miles. We begin to keep close watch on objects that could pass within 5 million miles of our planet.

To put that into perspective, our Moon is only 238,900 miles away.

However unlikely an impact is, we want to know about all near-Earth objects. Our Planetary Defense Coordination Office maintains watch for asteroids and comets coming close to Earth. Along with our partners, we discover, catalog and characterize these bodies.

But what if one of these objects posed a threat?

We want to be prepared. That is why we are working on several deflection techniques and technologies to help protect our planet.

So next time that you hear of an asteroid passing “close” to Earth, know that it’s just one of many that we are tracking.

Here are 10 more things you should know about Planetary Defense.

Mars Helicopter: 6 Things to Know About Ingenuity

When our Perseverance Mars rover lands on the Red Planet on Feb. 18, 2021, it will bring along the Ingenuity helicopter.

This small-but-mighty craft is a technology demonstration that will attempt the first powered, controlled flight on another planet. Its fuselage is about the size of a tissue box, and it weighs about 4 pounds (1.8 kg) on Earth. It started out six years ago as an implausible prospect and has now passed its Earthbound tests.

Here are six things to know about Ingenuity as it nears Mars:

1. Ingenuity is an experimental flight test.

This Mars helicopter is known as a technology demonstration, which is a project that aims to test a new capability for the first time with a limited scope. Previous technology demonstrations include Sojourner, the first Mars rover, and the Mars Cube One (MarCO) CubeStats that flew by Mars.

Ingenuity does not carry any science instruments and is not part of Perseverance’s science mission. The only objective for this helicopter is an engineering one – to demonstrate rotorcraft flight in the thin and challenging Martian atmosphere.

2. Mars won’t make it easy for Ingenuity.

Mars’ atmosphere is around 1% the density of Earth’s. Because of that lack of density, Ingenuity has rotor blades that are much larger and spin faster than a helicopter of Ingenuity’s mass here on our planet. It also must be extremely light to travel to Mars.

The Red Planet also has incredibly cold temperatures, with nights reaching minus 130 degrees Fahrenheit (-90 degrees Celsius) in Jezero Crater, where our rover and helicopter will land. Tests on Earth at the predicted temperatures indicate Ingenuity’s parts should work as designed, but the real test will be on Mars.

3. Ingenuity relies on Perseverance for safe passage to Mars and operations on the Martian surface.

Ingenuity is nestled sideways under Perseverance’s belly with a cover to protect the helicopter from debris during landing. The power system on the Mars 2020 spacecraft periodically charges Ingenuity’s batteries during the journey to the Red Planet.

In the first few months after landing, Perseverance will find a safe place for Ingenuity. Our rover will shed the landing cover, rotate the helicopter so its legs face the ground and gently drop it on the Martian surface.

4. Ingenuity is smart for a small robot.

NASA’s Jet Propulsion Laboratory will not be able to control the helicopter with a joystick due to delays communicating with spacecraft across interplanetary distances. That means Ingenuity will make some of its own decisions based on parameters set by its engineering team on Earth.

During flight, Ingenuity will analyze sensor data and images of the terrain to ensure it stays on a flight path designed by project engineers.

5. The Ingenuity team counts success one step at a time.

Ingenuity’s team has a long list of milestones the helicopter must pass before it can take off and land in the Martian atmosphere.

Surviving the journey to and landing on Mars

Safely deploying onto the Martian surface from Perseverance’s belly

Autonomously keeping warm through those intensely cold Martian nights

Autonomously charging itself with its solar panel

Successfully communicating to and from the helicopter via the Mars Helicopter Base Station on Perseverance

6. If Ingenuity succeeds, future Mars exploration could include an ambitious aerial dimension.

The Mars helicopter intends to demonstrate technologies and first-of-its-kind operations needed for flying on Mars. If successful, these technologies and flight experience on another planet could pave the way for other advanced robotic flying vehicles.

Possible uses of a future helicopter on Mars include:

A unique viewpoint not provided by current orbiters, rovers or landers

High-definition images and reconnaissance for robots or humans

Access to terrain that is difficult for rovers to reach

Could even carry light but vital payloads from one site to another

Small Business Saturday: Space Edition!

Today is Small Business Saturday, an annual campaign that American Express started back in 2010 on the Saturday after Thanksgiving to support “local places that make our communities strong.”

The U.S. Senate has even taken note by passing a bipartisan resolution recognizing November 25, 2017 as Small Business Saturday: “an opportunity for all Americans to rally behind these local, independently-owned businesses and support the entrepreneurs who keep our families employed.”

Here at NASA, we look to promote and integrate small businesses across the country into the work we do to pioneer the future of space exploration, scientific discovery and aeronautics research.

Our Small Business Innovative Research (SBIR) and Small Business Technology Transfer (STTR) program seeks to fund the research, development and demonstration of innovative technologies that help address space exploration challenges and have significant potential for commercialization. In fiscal year 2017, our program awarded 567 contracts to 277 small businesses and 44 research institutions for a total of $173.5M that will enable our future missions into deep space and advancements in aviation and science, while also benefiting the U.S. economy. This year, the SBIR/STTR program’s Economic Impact Report indicated a $2.74 return for every dollar spent on awards—money well spent!

Our small business partners’ ideas have helped our work become more efficient and have advanced scientific knowledge on the International Space Station. Over 800 small businesses are contributing to the development of our Space Launch System rocket that will carry humans to deep space. SBIR/STTR program awardees are also helping the Curiosity Rover get around Mars and are even preparing the Mars 2020 Rover to search for signs of potential life on the Red Planet.

Small businesses are also contributing to scientific advances here on Earth like helping our satellites get a clearer picture of soil moisture in order to support water management, agriculture, and fire, flood and drought hazard monitoring.

In an effort to improve our understanding of the Arctic and Antarctica, a small business developed a cost-saving unmanned aircraft system that could withstand some of the coldest temperatures on the planet.

Does your small business have a big idea? Your next opportunity to join the SBIR/STTR program starts on January 11, 2018 when our latest solicitation opens. 

We’ll be seeking new ideas from small businesses and research institutions for research, development and demonstration of innovative technologies. Go to www.nasa.sbir.gov to learn more.

Solar System: Things to Know This Week

Discoveries in planetary science are often both weird and wonderful, and these newest announcements are no exception. This week we present a few of the most interesting recent scientific findings from our missions and NASA-funded planetary science. Take a look:

1. Seeing Spots

Scientists from our Dawn mission unveiled new images from the spacecraft’s lowest orbit at the dwarf planet Ceres, including highly anticipated views of the famous “bright spots” of Occator Crater. Take a look HERE.

2. Pluto’s Secrets Brought to Light

A year ago, Pluto was just a bright speck in the cameras of our approaching New Horizons spacecraft, not much different than its appearances in telescopes since Clyde Tombaugh discovered the dwarf planet in 1930. Now, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby. Find out more HERE.

3. Rising Above the Rest

In a nod to extraterrestrial mountaineers of the future, scientists working on our Cassini mission have identified the highest point on Saturn’s largest moon, Titan. The tallest peak is 10,948 feet (3,337 meters) high and is found within a trio of mountainous ridges called the Mithrim Montes, named for the mountains in Tolkien’s Middle-Earth.

4. Does the “Man in the Moon” Have a New Face?

New NASA-funded research provides evidence that the spin axis of Earth’s moon shifted by about five degrees roughly three billion years ago. The evidence of this motion is recorded in the distribution of ancient lunar ice, evidence of delivery of water to the early solar system.

5. X-Ray Vision

Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s “northern lights,” according to a new study using data from our Chandra X-ray Observatory.

10 Frequently Asked Questions About the James Webb Space Telescope

Got basic questions about the James Webb Space Telescope and what amazing things we’ll learn from it? We’ve got your answers right here! 

The James Webb Space Telescope, or Webb, is our upcoming infrared space observatory, which will launch in 2021. It will spy the first luminous objects that formed in the universe and shed light on how galaxies evolve, how stars and planetary systems are born, and how life could form on other planets.

1. What is the James Webb Space Telescope?

Our James Webb Space Telescope is a giant space telescope that observes infrared light. Rather than a replacement for the Hubble Space Telescope, it’s a scientific successor that will complement and extend its discoveries.

Being able to see longer wavelengths of light than Hubble and having greatly improved sensitivity will let Webb look further back in time to see the first galaxies that formed in the early universe, and to peer inside dust clouds where stars and planetary systems are forming today.

2. What are the most exciting things we will learn?

We have yet to observe the era of our universe’s history when galaxies began to form. 

We have a lot to learn about how galaxies got supermassive black holes in their centers, and we don't really know whether the black holes caused the galaxies to form or vice versa.

We can't see inside dust clouds with high resolution, where stars and planets are being born nearby, but Webb will be able to do just that. 

We don't know how many planetary systems might be hospitable to life, but Webb could tell whether some Earth-like planets have enough water to have oceans.

We don't know much about dark matter or dark energy, but we expect to learn more about where the dark matter is now, and we hope to learn the history of the acceleration of the universe that we attribute to dark energy. 

And then, there are the surprises we can't imagine!

3. Why is Webb an infrared telescope?

By viewing the universe at infrared wavelengths with such sensitivity, Webb will show us things never before seen by any other telescope. For example, it is only at infrared wavelengths that we can see the first stars and galaxies forming after the Big Bang. 

And it is with infrared light that we can see stars and planetary systems forming inside clouds of dust that are opaque to visible light, such as in the above visible and infrared light comparison image of the Carina Nebula.

4. Will Webb take amazing pictures like Hubble? Can Webb see visible light?

YES, Webb will take amazing pictures! We are going to be looking at things we've never seen before and looking at things we have seen before in completely new ways.

The beauty and quality of an astronomical image depends on two things: the sharpness and the number of pixels in the camera. On both of these counts, Webb is very similar to, and in many ways better than, Hubble. 

Additionally Webb can see orange and red visible light. Webb images will be different, but just as beautiful as Hubble's. Above, there is another comparison of infrared and visible light Hubble images, this time of the Monkey Head Nebula.

5. What will Webb's first targets be?

The first targets for Webb will be determined through a process similar to that used for the Hubble Space Telescope and will involve our experts, the European Space Agency (ESA), the Canadian Space Agency (CSA), and scientific community participants.

The first engineering target will come before the first science target and will be used to align the mirror segments and focus the telescope. That will probably be a relatively bright star or possibly a star field.

6. How does Webb compare with Hubble?

Webb is designed to look deeper into space to see the earliest stars and galaxies that formed in the universe and to look deep into nearby dust clouds to study the formation of stars and planets.

In order to do this, Webb has a much larger primary mirror than Hubble (2.5 times larger in diameter, or about 6 times larger in area), giving it more light-gathering power. It also will have infrared instruments with longer wavelength coverage and greatly improved sensitivity than Hubble. 

Finally, Webb will operate much farther from Earth, maintaining its extremely cold operating temperature, stable pointing and higher observing efficiency than with the Earth-orbiting Hubble.

7. What will Webb tell us about planets outside our solar system? Will it take photos of these planets?

Webb will be able to tell us the composition of the atmospheres of planets outside our solar system, aka exoplanets. It will observe planetary atmospheres through the transit technique. A transit is when a planet moves across the disc of its parent star. 

Webb will also carry coronographs to enable photography of exoplanets (planets outside our solar system) near bright stars (if they are big and bright and far from the star), but they will be only "dots," not grand panoramas. Coronographs block the bright light of stars, which could hide nearby objects like exoplanets.

Consider how far away exoplanets are from us, and how small they are by comparison to this distance! We didn’t even know what Pluto really looked like until we were able to send an observatory to fly right near it in 2015, and Pluto is in our own solar system!

8. Will we image objects in our own solar system?

Yes! Webb will be able to observe the planets at or beyond the orbit of Mars, satellites, comets, asteroids and objects in the distant, icy Kuiper Belt.

Many important molecules, ices and minerals have strong characteristic signatures at the wavelengths Webb can observe. 

Webb will also monitor the weather of planets and their moons. 

Because the telescope and instruments have to be kept cold, Webb’s protective sunshield will block the inner solar system from view. This means that the Sun, Earth, Moon, Mercury, and Venus, and of course Sun-grazing comets and many known near-Earth objects cannot be observed.

9. How far back will Webb see? 

Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.

10. When will Webb launch and how long is the mission?

Webb will launch in 2021 from French Guiana on a European Space Agency Ariane 5 rocket. 

Webb’s mission lifetime after launch is designed to be at least 5-1/2 years, and could last longer than 10 years. The lifetime is limited by the amount of fuel used for maintaining the orbit, and by the possibility that Webb’s components will degrade over time in the harsh environment of space.

Our solar system is huge, let us break it down for you. Here are a few things to know this week:

1. The View from the Far Shore

The rugged shores of Pluto’s highlands come into sharp view in a newly released image from our New Horizons spacecraft. This latest view zooms in on the southeastern portion of Pluto’s great ice plains, where they border dark highlands formerly named Krun Macula.

2. Dawn’s Latest Light

Our Dawn mission has now completed more than 1,000 orbital revolutions since entering into Ceres’ gravitational grip in March 2015. The probe is healthy and performing its ambitious assignments impeccably. See what it has revealed lately HERE.

3. Counting Down

Our OSIRIS-REx mission to the asteroid Bennu is now entering the final preparations for its planned launch in September. In a new interview, the mission’s principal investigator reports on the final pre-flight tests happening at our Kennedy Space Center in Florida.

4. Deep Dive

Three successful engine maneuvers to bring the lowest part of the spacecraft’s orbit down to just 74 miles (119 km) above the surface of Mars, the MAVEN mission’s fifth deep dip campaign has begun. MAVEN is studying the planet’s atmosphere up close.

5. Storm Season

Meanwhile, other robotic Mars orbiters have revealed that a pattern of three large regional dust storms occurs with similar timing most Martian years. The seasonal pattern was detected from dust storms’ effects on atmospheric temperatures, which spacecraft have been monitoring since 1997.

Solar System 10 Things to Know This Week: Humans of NASA

Meet some of the amazing humans behind our exploring machines.

1—Small Town to Small Satellites

“I grew up in a small town where working at NASA was unheard of. I worked hard, persevered, and eventually made it to where I am despite many obstacles along the way. Through that process, never forget to enjoy what you are doing. It is my passion for space exploration that has helped me keep motivated and that brings me happiness every day that I come to work.”

—Farah Alibay, Engineer

2—Scientist. Mountain Unicyclist

“I do a rather unusual sport for fun—mountain unicycling. I love it because it's incredibly challenging, requiring strength, stamina and focus. I also enjoy surfing, caving, flying and teaching a space camp in South Korea each summer.”

—Morgan Cable, Research Scientist

3—"Eat. Breathe. Do Science. Sleep later."

“I do SCIENCE! No, seriously, I travel and explore for fun. It's a fascinating world and I can't get enough of it. But I'm always doing "science" of some kind no matter where I am. I love it —— can't escape it and wouldn't want to. Eat. Breathe. Do Science. Sleep later.”

—Derek Pitts, Solar System Ambassador

4—In the Room Where It Happened

“It was the summer of 2013, when I was the media rep for the Voyager mission. I was with Ed Stone, the mission's project scientist, when he came to the conclusion that Voyager 1 had crossed the threshold into interstellar space. For the first time, a human—made object flew beyond the plasma bubble our sun blows around itself. Voyager 1 is now bathed in the remnants of the explosions of other stars. I really appreciated seeing the scientific process—and Ed’s mind—at work.”

—Jia-Rui Cook, Supervisor of News Events and Projects at JPL

5—All About the Math. And Determination.

"From an academic point of view, it's all about doing well in math and science. However, there is absolutely no substitute for being determined. Being determined to be successful is at least half the game."

— James Green, Director of NASA’s Planetary Science Division

6—Problem Solver

“Opportunity [rover] was designed to live for 90 days in the harsh Martian environment but she is still exploring now 11 years later! Because of her age, software and hardware components are degrading on the vehicle and more recently, the flash memory. I had the incredible opportunity to lead the team to figure out how to solve these flash problems and get Opportunity back into an operational state.”

—Bekah Sosland Siegfriedt, Engineer

7—Never Give Up

"When you encounter difficulties or failures, do not take no for an answer. If you truly want to accomplish something and are passionate about it, you need to believe in yourself, put your mind to it, and you can accomplish anything! I failed A LOT, but I NEVER GAVE UP. It took three years and over 150 applications to NASA before I received my first internship"

—Kevin DeBruin, Systems Engineer

8—More Than Mohawk Guy

"The great thing about being at NASA is that there are jobs for all types —— whether it's engineering, science, finance, communication, law, and so forth. All of them are necessary and all of them involve working on some of the coolest things humans can do. So pick the area you love, but also know that you can still be a part of exploring the universe."

—Bobak Ferdowsi, Systems Engineer

9—The Power of One

“When my older sister claimed she would one day be an astronaut, on the heels of Sally Ride's launch into space, I made the same claim. Though, it was more because I dreamed to be just like my sister! In turned out that she outgrew the crazy dream, and my desire only got stronger.”

—Mamta Patel Nagaraja, Science Communications

10—Dedication and Choices

“Body-building is a favorite pasttime: it's a great stress reliever and a hobby that I can take with me when I travel for work or for pleasure. It's also a great expression of responsibility and ownership: What I've accomplished is due entirely to my dedication and choices, and it belongs to no one but me.”

—Troy Hudson, Instrument System Engineer

View these celestial beauties taken by the Hubble Space Telescope and released as a set of views in a modern day "Messier Catalog." 

Spotting comets was all the rage in the middle of the 18th century, and at the forefront of the comet hunt was a young French astronomer named Charles Messier. In 1774, in an effort to help fellow comet seekers steer clear of astronomical objects that were not comets (something that frustrated his own search for these elusive entities), Messier published the first version of his “Catalog of Nebulae and Star Clusters,” a collection of celestial objects that weren’t comets and should be avoided during comet hunting. Today, rather than avoiding these objects, many amateur astronomers actively seek them out as interesting targets to observe with backyard telescopes, binoculars or sometimes even with the naked eye.

Hubble’s version of the Messier catalog includes eight newly processed images never before released by NASA. The images were extracted from more than 1.3 million observations that now reside in the Hubble data archive. Some of these images represent the first Hubble views of the objects, while others include newer, higher resolution images taken with Hubble’s latest cameras.
