WASHINGTON (NASA PR) — The following selections, organized by topic area, are based on NASA’s fifth competitive Tipping Point solicitation and have an expected combined award value of more than $370 million. NASA’s Space Technology Mission Directorate (STMD) will negotiate with the companies to issue milestone-based firm-fixed price contracts lasting for up to five years.
HUNTSVILLE, Ala. (NASA PR) — As part of the Artemis program, NASA is returning astronauts to the Moon where we will prepare for human exploration of Mars. Additive manufacturing, or 3D printing, experts from NASA, industry, and academia are pioneering methods to print the rocket parts that could power those journeys.
EDWARDS, Calif. (NASA PR) — Mark the big one-of-a-kind engine, designed and built just for NASA, as delivered.
Nearly 13 feet long, three feet in diameter, and packing 22,000 pounds of afterburner enhanced jet propulsion, the F414-GE-100 engine is now at NASA’s Armstrong Flight Research Center on Edwards Air Force Base in California.
CLEVELAND (NASA PR) — NASA’s Glenn Research Center and University Hospitals (UH) in Cleveland have collaborated to develop new methods and technologies for decontaminating personal protective equipment (PPE) for aerospace applications and for safeguarding the health of workers caring for patients with coronavirus (COVID-19).
COLUMBIA, MD (USRA PR) — NASA has been conducting a series of space fire experiments called Spacecraft Fire Safety (Saffire) Experiments that investigate how fires grow and spread in space, especially aboard future spacecraft bound for Moon and Mars. Recently, another set of experiments were conducted when Saffire IV lit longer and stronger flames inside Northrop Grumman’s Cygnus Cargo spacecraft.
KENNEDY SPACE CENTER, Fla. (NASA PR) — When you think about what astronauts do in space, you probably don’t picture them taking out the trash.
As NASA prepares to return astronauts to the Moon and then venture to Mars, a lot of planning goes into how to keep crews safe and healthy and enable them to do as much science as possible. One of the challenges is how to handle trash. The Orbital Syngas/Commodity Augmentation Reactor (OSCAR) project, is an avenue to evolve new and innovative technology for dealing with garbage in space.
NASA’s planetary defense mission to deflect a small asteroid continues to move toward a February 2022 launch date while holding to its $313.9 million budget, according to a new assessment by the Government Accountability Office (GAO).
The Double Asteroid Redirection Test (DART) will fly to the binary asteroid Didymos and impact the smaller of the two bodies to assess techniques for deflecting dangerous asteroids on collision courses with Earth.
REDMOND, Wash., May 19, 2020 (Aerojet Rocketdyne PR) – The dual chemical and electric propulsion systems for NASA’s Double Asteroid Redirection Test (DART) were recently delivered by Aerojet Rocketdyne to the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
The chemical propulsion system and the electric propulsion Xenon feed system have been undergoing assembly and integration onto the spacecraft structure at Aerojet Rocketdyne’s facility in Redmond, Washington, since August 2019.
CLEVELAND (NASA PR) — It’s rocky. It’s sandy. It’s flat. It’s cratered. It’s cold. The surface of Mars is a challenging and inhospitable place, especially for rovers. As future missions to Mars become more complex, NASA’s robotic wanderers will need new technologies to look deeper into the history of the Red Planet.
One of those technologies is an innovative new tire in development at NASA’s Glenn Research Center using innovative shape memory alloys (SMA).

Magneto-Inductive Communications for Ocean Worlds
Robert Romanofsky NASA Glenn Research Center
A mission to the under-ice ocean of Europa is one of the highest priority missions for NASA. Galileo magnetometer measurements and other observations suggest a deep layer of electrically conductive fluid beneath the surface. Concepts for a probe to melt through the 5 to 10 km thickness of briny ice to reach the buried ocean have been proposed.
Model predictions for magnesium sulfide concentrations vary but a conductivity range between 0.1 and 3 S/m seems reasonable. Conventional communications links that rely on propagation of an electromagnetic field cannot penetrate – even if the sea ice conductivity is only 0.1 S/m. The electric field attenuation would exceed 100 dB/km even at very low frequencies.
WASHINGTON (NASA PR) — NASA has joined the fight against coronavirus (COVID-19) with efforts underway across the country to augment the national response, a few of which were highlighted in a media briefing today.
WASHINGTON, March 20, 2020 (NASA PR) — To protect the health and safety of the NASA workforce as the nation responds to coronavirus (COVID-19), agency leadership recently completed the first assessment of work underway across all missions, projects, and programs. The goal was to identify tasks that can be done remotely by employees at home, mission-essential work that must be performed on-site, and on-site work that will be paused.
“We are going to take care of our people. That’s our first priority,” said NASA Administrator Jim Bridenstine. “Technology allows us to do a lot of what we need to do remotely, but, where hands-on work is required, it is difficult or impossible to comply with CDC guidelines while processing spaceflight hardware, and where we can’t safely do that we’re going to have to suspend work and focus on the mission critical activities.”
CLEVELAND (NASA PR) — After undergoing a series of performance and environmental tests, NASA’s Evolutionary Xenon Thruster – Commercial (NEXT-C) is being prepared for the Double Asteroid Redirection Test (DART) Mission, which will launch next year.
In the past few months, the thruster, developed at NASA’s Glenn Research Center in Cleveland and designed and built by Aerojet Rocketdyne, was put through vibration, thermal vacuum and performance tests and then integrated with its power processing unit. The environmental testing verified that NEXT-C could withstand the extreme launch vibrations and temperatures of spaceflight.
DART will be the first space mission to demonstrate asteroid deflection by kinetic impact, a technique that could prevent a hazardous asteroid from impacting Earth by changing the motion of the asteroid in space. NEXT-C’s propulsion system will be tested on that mission, along with several other technologies.
When the propulsion system is successfully demonstrated on DART, NEXT-C will be considered on a variety of 10 to 15 year-long, uncrewed missions that could include going to other asteroids, comets or planets such as Venus.
CLEVELAND (NASA PR) — An engineering model of the Volatiles Investigating Polar Exploration Rover, or VIPER, is tested in the Simulated Lunar Operations Laboratory at NASA’s Glenn Research Center in Cleveland, Ohio.
About the size of a golf cart, VIPER is a mobile robot that will roam around the Moon’s South Pole looking for water ice in the region and for the first time ever, actually sample the water ice at the same pole where the first woman and next man will land in 2024 under the Artemis program.
The large, adjustable soil bin contains lunar simulant and allows engineers to mimic the Moon’s terrain. Engineers from NASA’s Johnson Space Center in Houston, where the rover was designed and built, joined the Glenn team to complete the tests.
Test data will be used to evaluate the traction of the vehicle and wheels, determine the power requirements for a variety of maneuvers and compare methods of traversing steep slopes. Respirators are worn by researchers to protect against the airborne silica that is present during testing.
VIPER is a collaboration within and beyond the agency. NASA’s Ames Research Center in Silicon Valley is managing the project, leading the mission’s science, systems engineering, real-time rover surface operations and software.
The rover’s instruments are provided by Ames, NASA’s Kennedy Space Center in Florida and commercial partner, Honeybee Robotics in California. The spacecraft, lander and launch vehicle that will deliver VIPER to the surface of the Moon will be provided through NASA’s Commercial Lunar Payload Services program, delivering science and technology payloads to and near the Moon.
CLEVELAND — Imagine you just moved to the surface of the Moon. There is plenty of available real estate, and you pick a nice-looking plot, away from craters and burnt-out volcanoes, for your home. You begin building on the powdery surface, first putting up walls, and then using a device like an inkjet printer to print solar cells that will generate your electricity. Once you finish, you step inside, turn out the lights and close the blinds to block the Sun that won’t set for another 14 Earth days.
