	March 29, 2018  MEDIA ADVISORY M18-055 NASA to Host News Conference Announcing New Supersonic Test Aircraft NASA will host a news conference at 11 a.m. EDT Tuesday, April 3, to announce the agency's plans for its next experimental aircraft, or X-plane, called the Low-Boom Flight Demonstrator (LBFD). In February 2016, NASA signed a contract for the preliminary design of its LBFD concept. The agency now is ready to move forward with development and building of the aircraft, which will test new technology for quiet supersonic flight and possibly enable changes that will allow for supersonic flights over land. The news conference will be held in the James E. Webb Auditorium at NASA Headquarters at 300 E St. SW in Washington, and also will air live on NASA Television and the agency's website. The briefing participants are: Jaiwon Shin, associate administrator of NASA's Aeronautics Research Mission Directorate. Ed Waggoner, program director for NASA's Integrated Aviation Systems Program Peter Coen, project manager for NASA's Commercial Supersonics Technology Project Media planning to attend or call in to the news conference should email their name, media affiliation and telephone number to J.D. Harrington at j.d.harrington@nasa.gov no later than 9 a.m. April 3. Media and the public can send questions on Twitter during the news conference using #AskNASA.

	March 29, 2018  RELEASE 18-021 NASA Ready to Study Heart of Mars An artist's rendering of a rocket launching with the InSight spacecraft later this May. Credits: NASA/JPL-Caltech NASA is about to go on a journey to study the interior of Mars. The space agency held a news conference today at its Jet Propulsion Laboratory (JPL) in Pasadena, California, detailing the next mission to the Red Planet. Scheduled to launch as early as May 5, NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight), a stationary lander, will be the first-ever mission dedicated to exploring Mars' deep interior. It also will be the first NASA mission since the Apollo moon landings to place a seismometer, a device that measures quakes, on the soil of another planet. For JPL's Bruce Banerdt, principal investigator for InSight, it's also a labor of love. Banerdt has worked more than 25 years to make the mission a reality. "In some ways, InSight is like a scientific time machine that will bring back information about the earliest stages of Mars' formation 4.5 billion years ago," Banerdt said. "It will help us learn how rocky bodies form, including Earth, its moon, and even planets in other solar systems." InSight carries a suite of sensitive instruments to gather data and, unlike a rover mission, these instruments require a stationary lander from which they can carefully be placed on and below the Martian surface. In a sense, Mars is the exoplanet next door – a nearby example of how gas, dust and heat combine and arrange themselves into a planet. Looking deep into Mars will let scientists understand how different its crust, mantle and core are from Earth. NASA isn't the only agency excited about the mission. Several European partners contributed instruments or instrument components to the InSight mission. France's Centre National d'Études Spatiales led a multinational team that built an ultra-sensitive seismometer for detecting marsquakes. The German Aerospace Center (DLR) developed a thermal probe that can bury itself up to 16 feet (5 meters) underground and measure heat flowing from inside the planet. "InSight is a truly international space mission," said Tom Hoffman, project manager at JPL. "Our partners have delivered incredibly capable instruments that will make it possible to gather unique science after we land." InSight currently is at Vandenberg Air Force Base in California undergoing final preparation before launch. On Wednesday, it completed what's known as a spin test: the entire spacecraft is rotated at high speeds to confirm its center of gravity. That's critical for its entry, descent and landing on Mars in November, Hoffman said. In the next month, the spacecraft will be mounted to its rocket, connections between them will be checked, and the launch team will go through a final training. "This next month will be exciting," Banerdt said. "We've got some final work to do, but we're almost ready to go to Mars." JPL manages the InSight Project for NASA's Science Mission Directorate in Washington. Lockheed Martin Space in Denver built and tested the spacecraft. InSight is part of NASA's Discovery Program, which is managed by the agency's Marshall Space Flight Center in Huntsville, Alabama.
