MEDIA ADVISORY M18-078 NASA Hosts Live Discussion about Europa Findings, Potential for Life

NASA will host a Science Chat at 1 p.m. EDT Monday, May 14, to discuss the latest analysis of Jupiter’s moon Europa and its status as one of the most promising places in the solar system to search for life. The event will air live on NASA Television, Facebook Live, Twitch TV, Ustream, YouTube, Twitter/Periscope and the agency's website.

Europa has long been a high priority for exploration because beneath its icy crust lies a salty, liquid water ocean. NASA’s Europa Clipper, targeted to launch in 2022, will be equipped with the instruments necessary to determine whether Europa possesses the ingredients necessary to support life as we know it.

Lori Glaze, acting director of NASA’s Planetary Science Division (PSD), and JoAnna Wendel, PSD communications lead, will host the chat. Guests include:

• Xianzhe Jia, associate professor in the Department of Climate and Space Sciences and Engineering at the University of Michigan, Ann Arbor
• Elizabeth Turtle, research scientist at Johns Hopkins Applied Physics Laboratory in Laurel, Maryland
• Margaret Kivelson, professor emerita of Space Physics in the Department of Earth and Space Sciences at the University of California, Los Angeles

Media who would like to ask questions during the event must email their name, media affiliation and phone number to Felicia Chouat felicia.chou@nasa.gov by 12:30 p.m. Monday, May 14.

The public can send questions on social media by using #AskNASA at any time during the event.

MEDIA ADVISORY M18-077 Oklahoma, Illinois Students to Link Up with NASA Astronauts on Space Station

Students from Tulsa, Oklahoma, and Edwardsville, Illinois, will have the opportunity to talk with astronauts on the International Space Station next week as part of NASA’s Year of Education on Station. The two 20-minute, Earth-to-space calls will air live on NASA TV and the agency’s website.

NASA astronauts Ricky Arnold and Drew Feustel will answer questions about life aboard the space station, NASA’s deep space exploration plans and conducting science in space during both opportunities.

The first event will connect Oklahoma students from several schools in grades 5 through 12 with the two Expedition 55 astronauts at 10:35 a.m. EDT Monday, May 14, from the Tulsa Air and Space Museum & Planetarium. The students submitted essays describing what they would ask an astronaut and how that question relates to their own lives on Earth as part of the selection process. Media interested in attending should contact Kevin Meeks at kmeeks@tulsamuseum.org or 918-834-9900. The event will take place at the museum, 3624 North 74th East Ave., Tulsa.

The second event will allow eighth grade students from Liberty and Lincoln Middle Schools in Edwardsville to speak with Feustel and Arnold at 10:10 a.m. Friday, May 18. Media interested in attending should contact Beth Jacobs at ejacobs@ecusd7.org or 618-655-6055. The event will take place at Liberty Middle School, #1 District Dr., Edwardsville.

Linking teachers directly to astronauts aboard the space station provides unique, authentic experiences designed to enhance student learning, performance and interest in science, technology, engineering and mathematics (STEM). These in-flight education downlinks are an integral component of NASA’s Year of Education on Station, which provides extensive space station-related resources and opportunities to students and educators. Astronauts living in space on the orbiting laboratory communicate with the Mission Control Center on Earth 24 hours a day through the Space Network's Tracking and Data Relay Satellites (TDRS).

In addition to the educational events, Feustel and fellow NASA astronaut Scott Tingle will be interviewed by the USA Today Network, and the “Off Track with Hinch and Rossi” podcast from the Indianapolis Motor Speedway at 9:35 a.m. Thursday, May 17.

Feustel and Arnold will participate a downlink opportunity and will answer pre-submitted questions in a Tumblr “Answer Time” at 1 p.m. on May 18. These questions will be posted on the NASA Tumblr account at a later date.

MEDIA ADVISORY M18-079 NASA Television to Air Coverage of Earth-Observing Satellite Duo Launch

Media are invited to cover the prelaunch briefing and launch of the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO), NASA’s latest Earth-observing satellite mission. The briefing on Thursday, May 17, and launch on Saturday, May 19, will air on NASA Television and the agency’s website.

A joint mission with the German Research Centre for Geosciences (GFZ), GRACE-FO will provide critical measurements that will be used together with other data to monitor the movement of water masses across the planet and mass changes within Earth itself. Monitoring changes in ice sheets and glaciers, underground water storage, and sea level provides a unique view of Earth’s climate and has far-reaching benefits. The mission is planned to fly at least five years.

The prelaunch news briefing will be held at 2 p.m. EDT May 17 at Vandenberg. Media who wish to participate by phone must contact Elena Mejia at elena.mejia@jpl.nasa.gov or 818-354-1712, no later than 12:30 p.m. May 17.

Briefing participants will be:

• David Jarrett, GRACE-FO program executive in the Earth Science Division at NASA Headquarters
• Frank Webb, GRACE-FO project scientist at NASA’s Jet Propulsion Laboratory (JPL)
• Frank Flechtner, GRACE-FO project manager at GFZ
• Phil Morton, NASA GRACE-FO project manager at JPL
• Capt. Jennifer Haden, weather officer for the 30th Space Wing at Vandenberg

The satellites are scheduled to launch on a SpaceX Falcon 9 rocket at 4:04 p.m. EDT May 19 from Space Launch Complex-4E at Vandenberg Air Force Base in California. GRACE-FO will share its ride to orbit with five Iridium NEXT communications satellites as part of a commercial rideshare agreement. Launch coverage begins at 3:30 p.m. on NASA Television and the agency’s website.

JPL manages the GRACE-FO mission for the agency’s Science Mission Directorate in Washington. GFZ contracted GRACE-FO launch services from Iridium, and SpaceX is providing the Falcon 9 launch service.

RELEASE 18-035 Mars Helicopter to Fly on NASA’s Next Red Planet Rover Mission

NASA is sending a helicopter to Mars.

The Mars Helicopter, a small, autonomous rotorcraft, will travel with the agency’s Mars 2020 rover mission, currently scheduled to launch in July 2020, to demonstrate the viability and potential of heavier-than-air vehicles on the Red Planet.

“NASA has a proud history of firsts,” said NASA Administrator Jim Bridenstine. “The idea of a helicopter flying the skies of another planet is thrilling. The Mars Helicopter holds much promise for our future science, discovery, and exploration missions to Mars.”

U.S. Rep. John Culberson of Texas echoed Bridenstine’s appreciation of the impact of American firsts on the future of exploration and discovery.

“It’s fitting that the United States of America is the first nation in history to fly the first heavier-than-air craft on another world,” Culberson said. “This exciting and visionary achievement will inspire young people all over the United States to become scientists and engineers, paving the way for even greater discoveries in the future.”

Started in August 2013 as a technology development project at NASA’s Jet Propulsion Laboratory (JPL), the Mars Helicopter had to prove that big things could come in small packages. The result of the team’s four years of design, testing and redesign weighs in at little under four pounds (1.8 kilograms). Its fuselage is about the size of a softball, and its twin, counter-rotating blades will bite into the thin Martian atmosphere at almost 3,000 rpm – about 10 times the rate of a helicopter on Earth.

“Exploring the Red planet with NASA’s Mars Helicopter exemplifies a successful marriage of science and technology innovation and is a unique opportunity to advance Mars exploration for the future,” said Thomas Zurbuchen, Associate Administrator for NASA's Science Mission Directorate at the agency headquarters in Washington. “After the Wright Brothers proved 117 years ago that powered, sustained, and controlled flight was possible here on Earth, another group of American pioneers may prove the same can be done on another world.”

The helicopter also contains built-in capabilities needed for operation at Mars, including solar cells to charge its lithium-ion batteries, and a heating mechanism to keep it warm through the cold Martian nights. But before the helicopter can fly at Mars it has to get there. It will do so attached to the belly pan of the Mars 2020 rover.

“The altitude record for a helicopter flying here on Earth is about 40,000 feet. The atmosphere of Mars is only one percent that of Earth, so when our helicopter is on the Martian surface, it’s already at the Earth equivalent of 100,000 feet up,” said Mimi Aung, Mars Helicopter project manager at JPL. “To make it fly at that low atmospheric density, we had to scrutinize everything, make it as light as possible while being as strong and as powerful as it can possibly be.”

Once the rover is on the planet’s surface, a suitable location will be found to deploy the helicopter down from the vehicle and place it onto the ground. The rover then will be driven away from the helicopter to a safe distance from which it will relay commands. After its batteries are charged and a myriad of tests are performed, controllers on Earth will command the Mars Helicopter to take its first autonomous flight into history.

“We don’t have a pilot and Earth will be several light minutes away, so there is no way to joystick this mission in real time,” said Aung. “Instead, we have an autonomous capability that will be able to receive and interpret commands from the ground, and then fly the mission on its own.”

The full 30-day flight test campaign will include up to five flights of incrementally farther flight distances, up to a few hundred meters, and longer durations as long as 90 seconds, over a period. On its first flight, the helicopter will make a short vertical climb to 10 feet (3 meters), where it will hover for about 30 seconds.

As a technology demonstration, the Mars Helicopter is considered a high-risk, high-reward project. If it does not work, the Mars 2020 mission will not be impacted. If it does work, helicopters may have a real future as low-flying scouts and aerial vehicles to access locations not reachable by ground travel.

“The ability to see clearly what lies beyond the next hill is crucial for future explorers,” said Zurbuchen. “We already have great views of Mars from the surface as well as from orbit. With the added dimension of a bird’s-eye view from a ‘marscopter,’ we can only imagine what future missions will achieve.”

Mars 2020 will launch on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, and is expected to reach Mars in February 2021.

The rover will conduct geological assessments of its landing site on Mars, determine the habitability of the environment, search for signs of ancient Martian life, and assess natural resources and hazards for future human explorers. Scientists will use the instruments aboard the rover to identify and collect samples of rock and soil, encase them in sealed tubes, and leave them on the planet’s surface for potential return to Earth on a future Mars mission.

The Mars 2020 Project at JPL in Pasadena, California, manages rover development for the Science Mission Directorate at NASA Headquarters in Washington. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, is responsible for launch management.
