After 20 Years In Space, The Cassini Spacecraft Is Running Out Of Fuel. In 2010, Cassini Began A Seven-year

10 Technologies That Are Changing the Game

Earlier this year, we hosted a Game Changing Technology Industry Day for the aerospace industry, and in October our engineers and technologists visited Capitol Hill showcasing some of these exciting innovations. Check out these technology developments that could soon be making waves on Earth and in space.

1. Wearable technology

With smartwatches, glasses, and headsets already captivating users around the world, it’s no surprise that the next evolution of wearable technology could be used by first responders at the scene of an accident or by soldiers on a battlefield. The Integrated Display and Environmental Awareness System (IDEAS) is an interactive optical computer that works for smart glasses. 

It has a transparent display, so users have an unobstructed view even during video conferences or while visualizing environmental data. 

And while the IDEAS prototype is an innovative solution to the challenges of in-space missions, it won’t just benefit astronauts -- this technology can be applied to countless fields here on Earth.

2. Every breath they take: life support technologies

Before astronauts can venture to Mars and beyond, we need to significantly upgrade our life support systems. The Next Generation Life Support project is developing technologies to allow astronauts to safely carry out longer duration missions beyond low-Earth orbit. 

The Variable Oxygen Regulator will improve the control of space suit pressure, with features for preventing decompression sickness. The Rapid Cycle Amine technology will remove carbon dioxide and humidity and greatly improve upon today’s current complex system.

3. 3-D printing (for more than just pizza)

New Advanced Manufacturing Technologies (AMT), such as 3-D printing, can help us build rocket parts more quickly and aid in building habitats on other planets. 

These manufacturing initiatives will result in innovative, cost-efficient solutions to many of our planetary missions. Back in 2014, the International Space Station’s 3-D printer manufactured the first 3-D printed object in space, paving the way to future long-term space expeditions. 

The object, a printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with us to design, build and test the 3-D printer.

4. Spacecraft landing gear

Large spacecraft entering the atmosphere of Mars will be traveling over five times the speed of sound, exposing the craft to extreme heat and drag forces. The Hypersonic Inflatable Aerodynamic Decelerator (HIAD) is designed to protect spacecraft from this environment with an inflatable structure that helps slow a craft for landing. 

To get astronauts and other heavy loads to the surface safely, these components must be very strong. The inflatable consists of a material 15 times stronger than steel, while the thermal protection system can withstand temperatures over 1600°C.

5. From heat shield technology to firefighter shelters

For the Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) project, we partnered with the U.S. Forest Service to develop safer, more effective emergency fire shelters for wild land firefighters. 

Using existing technology for flexible spacecraft heat shields like HIAD, we are building and testing new fire shelters composed of stacks of durable, insulated materials that could help protect the lives of firefighters.

6. Robots and rovers

Real life is looking a bit more like science fiction as Human Robotics Systems are becoming highly complex. They are amplifying human productivity and reducing mission risk by improving the effectiveness of human-robot teams. 

Our humanoid assistant Robonaut is currently aboard the International Space Station helping astronauts perform tasks.

A fleet of robotic spacecraft and rovers already on and around Mars is dramatically increasing our knowledge and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back data from the surface. 

This data will help us plan how to protect the astronauts who will explore Mars. 

Future missions like the Mars 2020 rover, seeking signs of past life, will demonstrate new technologies that could help astronauts survive on the Red Planet.

7. Robotic repairs

Currently, a satellite that is even partially damaged cannot be fixed in orbit. Instead, it must be disposed of, which is a lot of potential science lost.

Satellite Servicing technologies would make it possible to repair, upgrade, and even assemble spacecraft in orbit using robotics.

This can extend the lifespan of a mission, and also enable deeper space exploration. 

Restore-L, set to launch in 2020, is a mission that will demonstrate the ability to grab and refuel a satellite.

8. Low-cost spacecraft avionics controllers

Small satellites, or smallsats, are quickly becoming useful tools for both scientists and industry. However, the high cost of spacecraft avionics—the systems that guide and control the craft—often limits how and when smallsats can be sent into orbit by tagging along as payloads on larger launches. 

Using Affordable Vehicle Avionics (AVA) technology, we could launch many more small satellites using an inexpensive avionics controller. This device is smaller than a stack of six CD cases and weighs less than two pounds!

9. Making glass from metal

After a JPL research team of modern-day alchemists set about mixing their own alloys, they discovered that a glass made of metal had the wear resistance of a ceramic, was twice as strong as titanium, and could withstand the extreme cold of planetary surfaces, with temperatures below -150 degrees Fahrenheit.

Bulk Metallic Glass (BMG) gears would enable mechanisms to function without wasting energy on heaters. Most machines need to maintain a warmer temperature to run smoothly, which expends precious fuel and decreases the mission’s science return. 

By developing gearboxes made of BMG alloys, we can extend the life of a spacecraft and learn more about the far reaches of our solar system than ever before. Plus, given their extremely high melting points, metallic glasses can be cheaply manufactured into parts by injection molding, just like plastics.

10. Lighter, cheaper, safer spacecraft fuel tanks

Cryogenic propellant tanks are essential for holding fuel for launch vehicles like our Space Launch System—the world’s most powerful rocket. But the current method for building these tanks is costly and time-consuming, involving almost a mile of welded parts.

Advanced Near Net Shape Technology, part of our Advanced Manufacturing Technologies, is an innovative manufacturing process for constructing cryotanks, using cylinders that only have welds in one area. 

This makes the tank lighter, cheaper, and safer for astronauts, as there are fewer potentially defective welds.

Solar System: Things to Know  This Week

This week, we’re looking at MAVEN’s exploration of Mars, the Orionid meteor showers, Mercury’s “great valley” and more.

1. Celebrating MAVEN

MAVEN, the Mars Atmospheric and Volatile Evolution, was the second mission selected for our Mars Scout program and the first to explore the planet’s upper atmosphere . It launched on November 18, 2013 and entered orbit around Mars on September 21, 2014. 

+ MAVEN Quick Facts

2. Jupiter Moon Dance

This time-lapse sequence of Hubble Space Telescope images shows Jupiter’s moon Europa as it moved across the planet’s face over the course of 19 minutes. Europa is at the bottom center on Jupiter's disk, the Great Red Spot to the left and Europa's shadow to its right. The video was created by combining six snapshots taken in ultraviolet light with Hubble's Wide Field Camera 3.

3. The Orionid Meteor Shower

Orionid shower peaks November 28. Look for the constellation Orion in the Southeast sky by 9 p.m. Using binoculars, look for the Orion Nebula. 

4. Comet Warming Up!! 

Comet 45P/Honda-Mrkos-Pajdu áková will brighten to expected stunning binocular visibility in mid to late December, but is near Venus on November 23rd.

+ Track the Comet

5. Mercury’s "Great Valley"

A newly discovered "great valley" in the southern hemisphere of Mercury provides more evidence that the planet closest to the sun is shrinking. Using stereo images from our MESSENGER spacecraft to create a high-resolution map, scientists have discovered that revealed the broad valley -- more than 620 miles (1,000 kilometers) long -- extending into the Rembrandt basin, one of the largest and youngest impact basins on Mercury. About 250 miles (400 kilometers) wide and 2 miles (3 kilometers) deep, Mercury's great valley is smaller than Mars' Valles Marineris, but larger than North America's Grand Canyon and wider and deeper than the Great Rift Valley in East Africa.

What's your favorite part of the job?

Employee Training – It’s Kind of a Big Deal

This is what it would look like if you were training to #BeAnAstronaut! Astronaut candidates must train for two years before they become official NASA astronauts. After graduation, you can look forward to more skill building when training for upcoming missions. Let’s dive into some of the courses you can expect once you’re selected for the job: 

T-38 Jet Training 

All astronaut candidates must learn to safely operate in a T-38 jet, either as a pilot or crew. Because this is the one area of their training that is not a simulation and involves decisions with life or death consequences, it teaches them to think quickly and clearly in dynamic situations.

 Neutral Buoyancy Lab Training

The mission of the Neutral Buoyancy Lab (NBL) is to prepare astronauts for spacewalking outside the International Space Station! Astronauts are lowered into a large pool wearing full spacesuits. The pool is full of hardware that replicates what the space station is really like, so astronauts are able to practice tasks they can expect on a spacewalk such as going out the airlock, finding a good path to the work site and more! The NBL is beneficial because it gives astronauts the ability to be neutrally buoyant which simulates the effects of microgravity.

Geology Training

Geology training courses are specially tailored to the work astronauts will do from the International Space Station or on the next interplanetary mission! Astronauts learn the basic principles of geology, see rocks in their natural environment and handle samples from their class discussions. It’s less like memorizing the names of rocks and more like learning how geologists think and work. 

Wilderness Survival Training 

Before they end up in space, astronauts carry out a significant portion of their training in aircraft on Earth. It's unlikely, but possible, that one of those training planes could crash in a remote area and leave the humans on board to fend for themselves for a while. Knowing how to take care of their basic needs would be invaluable. Through the exercises, instructors hope to instill self-care and self-management skills, to develop teamwork skills, and to strengthen leadership abilities – all of which are valuable for working in the isolation of the wild or the isolation of space. 

Extreme Environment Training 

Astronauts participate in a variety of extreme environment training to prepare for the stresses of spaceflight. Pictured here, they are exploring the underground system of the Sa Grutta caves in Sardinia, Italy as a part of the European Astronaut Centre’s Cooperative Adventure for Valuing and Exercising human behavior and performance Skills (CAVES) expedition. Seasoned astronauts as well as rookies participate in the course and share experiences while learning how to improve leadership, teamwork, decision-making and problem-solving skills.

Virtual Reality Training

In our Virtual Reality Laboratory training facility at Johnson Space Center astronauts are able to immerse themselves in virtual reality to complete mission tasks and robotic operations before launching to space. The facility provides real time graphics and motion simulators integrated with a tendon-driven robotic device to provide the kinesthetic sensation of the mass and inertia characteristics of any large object (<500lb) being handled.

Solar System: Top 5 Things to Know This Week

1. A Ceres of Fortunate Events

Our Dawn mission continues its exploration at Ceres, and the team is working with the data coming back to Earth, looking for explanations for the tiny world’s strange features. Follow Dawn’s expedition HERE.

2. Icy Moon Rendezvous

One of the most interesting places in the entire solar system is Saturn’s moon Enceladus, with its underground ocean and spectacular geyser plume. This month, the Cassini spacecraft will be buzzing close by Enceladus several times, the last such encounters of the mission. On October 14, Cassini will perform a targeted flyby at a distance of just 1,142 miles (1,838 kilometers) over the moon’s northern latitudes. Ride along with Cassini HERE.

3. Make Your Own Mars Walkabout

You can retrace Opportunity’s journey, see where the Curiosity rover is now, or even follow along with fictional astronaut Mark Watney from The Martian movie using the free online app MarsTrek. The app lets you zoom in on almost any part of the planet and see images obtained by our spacecraft, so you can plan your on Red Planet excursion. Take a hike HERE.

4. Elusive Features on Jupiter

New imagery from our Hubble Space Telescope is capturing details never before seen on Jupiter. High-resolution maps and spinning globes, rendered in the 4K Ultra HD format, reveal an elusive wave and changes to Jupiter’s Great Red Spot. Explore Jupiter HERE.

5. Mr. Blue Sky

Another week, another amazing picture from Pluto. The first color images of Pluto’s atmospheric hazes, returned by our New Horizons spacecraft last week, reveal that the hazes are blue. Who would have expected a blue sky in the Kuiper Belt? Most of the data collected during July’s Pluto flyby remains aboard the spacecraft, but the team publishes new batches of pictures and other findings on a weekly basis. Keep up with the latest HERE.

🚀 A New Era of Human Spaceflight

Our Commercial Crew Program has worked with several American aerospace industry companies to facilitate the development of U.S. human spaceflight systems since 2010. The goal is to have safe, reliable and cost-effective access to and from the International Space Station and foster commercial access to other potential low-Earth orbit destinations.

We selected Boeing and SpaceX in September 2014 to transport crew to the International Space Station from the United States. These integrated spacecraft, rockets and associated systems will carry up to four astronauts on NASA missions, maintaining a space station crew of seven to maximize time dedicated to scientific research on the orbiting laboratory

We begin a new era of human spaceflight as American astronauts will once again launch on an American spacecraft and rocket from American soil to the International Space Station.

As part of our Commercial Crew Program, NASA astronauts Robert Behnken and Douglas Hurley will fly on SpaceX’s Crew Dragon spacecraft for an extended stay at the space station for the Demo-2 mission. Launch is scheduled for 4:33 p.m. EDT on Wednesday, May 27.

Demo-2 will be SpaceX’s final test flight to validate its crew transportation system, including the Crew Dragon spacecraft, Falcon 9 rocket, launch pad and operations capabilities. While docked to the space station, the crew will run tests to ensure the Crew Dragon is capable of remaining connected to the station for up to 210 days on future missions.

Our Commercial Crew Program is working with the American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space Station. Commercial transportation to and from the station will provide expanded utility, additional research time and broader opportunities for discovery on the orbiting laboratory.

The station is a critical testbed for us to understand and overcome the challenges of long-duration spaceflight. As commercial companies focus on providing human transportation services to and from low-Earth orbit, we are freed up to focus on building spacecraft and rockets for deep space missions.

Space is Hard

Earlier this week weather scrubbed our SpaceX launch to the International Space Station. NASA astronauts Robert Behnken and Douglas Hurley were strapped into their Crew Dragon spacecraft when ground teams called off the 4:33pm ET launch due to inclement weather brought on by Tropical Storm Bertha off the southeastern U.S. coast. The Falcon 9 rocket is healthy, but we want to get it right. Safety is paramount.⁣⁣⁣⁣⁣⁣
