NASA welcomed a new administrator, Jim Bridenstine, deputy administrator, Jim Morhard, and chief financial officer, Jeff DeWit, in 2018. Their focus is on firmly establishing the groundwork to send Americans back to the Moon sustainably, with plans to use the agencys lunar experience to prepare to send astronauts to Mars.
Our agencys accomplishments in 2018 are breathtaking. Weve inspired the world and created incredible new capabilities for our nation, Bridenstine said. This year, we landed on Mars for the seventh time, and America remains the only country to have landed on Mars successfully. We created new U.S.
commercial partnerships to land back on the Moon. We made breakthroughs in our quest to send humans farther into space than ever before. And, we contributed to remarkable advancements in aviation. I want to thank the entire NASA team for a fantastic year of American leadership in space, and I am confident we will build on our 2018 successes in 2019.
In 2018, NASA celebrated six decades of exploration, discoveries and cutting-edge technology development for the agencys 60th anniversary on Oct. 1. Bridenstine said, President Eisenhower launched our nation into the Space Age and President Kennedy gave us the charge to reach the Moon. Over six incredible decades, we have brought the world an amazing number of bold missions in science, aviation and human exploration. NASA and its workforce have never failed to raise the bar of human potential and blaze a trail to the future. We celebrate our legacy today with great promise and a strong direction from the President to return to the Moon and go on to Mars.
The Office of the Chief Financial Officer received a successful clean audit in 2018 the eighth consecutive clean financial audit opinion for the agency. In addition, DeWit led his Strategic Investments Division in working with the Government Accounting Office to pass an official Corrective Action Plan for only the second time in NASAs history, which will increase accountability and transparency into the costs of large programs and proactively improve NASAs program and project management activities.
On Dec. 11, NASA recently marked the one-year anniversary of Space Policy Directive-1 (SPD-1), which provided a directive for NASA to return humans to the surface of the moon for long-term exploration and utilization and pursue human exploration of Mars and the broader solar system. Two additional space policy directives were enacted this year by the White House, with SPD-2 in February helping ease the regulatory environment so entrepreneurs can thrive in space, and SPD-3 in June helping ensure the U.S. is a leader in providing a safe and secure environment as commercial and civil space traffic increases.
Moon to Mars
America's return to the Moon will begin with U.S. commercial delivery services of small scientific instruments, followed by development of an infrastructure in orbit around the Moon to support human missions to the lunar surface, Mars and destinations beyond, for decades to come. Highlights from 2018 include:
- In October, NASA issued a call for lunar surface instruments and technology payloads that will fly to the Moon on commercial lunar landers as early as next year.On Nov. 29, the agency announced nine U.S. companies are eligible to bid on NASA delivery services to the lunar surface through Commercial Lunar Payload Services (CLPS) contracts.
- After receiving more than 190 scientific abstracts from the research community, NASA hosted a conference in February for scientists across a variety of disciplines to discuss future exploration and research using the Gateway, a spacecraft that will orbit the Moon and support human and robotic missions.
- In an effort to lay the foundation for partnerships with U.S. industry in several aspects of Gateway development and operation, NASA issued in 2018 several requests for information and ideas from U.S. companies about the Gateways use and supply, as well as lunar payload transportation capabilities, and construction of its power and propulsion element.
- NASA continued to refine requirements for a U.S. habitat module for the Gateway and technology to use and process space-based resources through the Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2).
The transportation system that will carry astronauts from Earth to the Gateway, and help build the structure in orbit, continued to take shape in 2018 with more flight hardware coming together around the country for the first launch of NASAs Space Launch System (SLS) rocket and Orion spacecraft.
- NASA delivered the second piece of SLS flight hardware to its Kennedy Space Center in Florida earlier this year. The Orion stage adapter will connect the spacecraft to SLS and will be loaded with13 small satelliteson the first mission.
- Engineers are completing final outfitting and assembly of thefivemajor structural pieces of the SLS core stage at NASAs Michoud Assembly Facility in New Orleans.
- Engineers at NASAs Marshall Space Flight Center in Huntsville, Alabama, are putting the finishing touches on the 30-foot-talllaunch vehicle stage adapter, which will connect SLS core stage to the interim cryogenic propulsion stage delivered to Kennedy last year.
- Engineers at Kennedy installedOrions reentry heat shield
- ESA (European Space Agency) delivered to Kennedy the service module that will propel, power and cool Orion during the first integrated flight test with SLS Exploration Mission 1.
- Workers at Kennedy also completed constructionon the main flame deflector at Launch Pad 39B, and engineers installed thefinal umbilicalon themobile launcher before rolling themassivetower on Crawler-Transporter 2to the pad.
It was a great year for robotic exploration of Mars, as well:
- NASAs Curiosity rover identified fragments of complex organic molecules in the shallow surface of Mars, giving us further evidence that the Red Planet could have hosted life at one point.
- NASA launched and landed the first spacecraft to set down on the Red Planet since Curiosity arrived in 2012 the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight). InSight touched down on Martian soil in November to study the planets interior and, just 10 days after landing, provided the first ever "sounds" of winds on Mars.
- NASA also announced the landing site for its next Red Planet rover, Mars 2020, which will continue the agencys efforts to search for evidence of life and prepare for human arrival.
Other highlights in the agencys progress this year in supporting the new Moon to Mars exploration approach include:
- More than 4,300 hours of testing completed on Solar Electric Propulsion (SEP) Hall thrusters.
- Orion pressure vessel for first crewed flight shippedto Kennedy.
- Final test of Orionsparachute system.
- Preparation for test of Orions launch abort system.
- Several parts of SLS in production, or completed, for second mission.
- New seriesof SLS RS-25 engine test firings included nine tests of3D-printed parts.
- First combination 3D printer and recycler launched to International Space Station to demonstrate new in-space manufacturing technology.

- Ten companies chosen to conduct studies and advance technologies to collect and use space-based resources.
- 3D-Printed Habitat Challenge progressed as participating teams created digital models of Martian habitats and constructed and tested foundation prototypes.
Solar System and Beyond
In 2018, NASA bid farewell to two veteran science spacecraft, launched a record-breaking mission to the Sun, and continued to make discoveries with current missions and progress on future missions. Highlights from the year include:
- NASAs Parker Solar Probe launched on the first-ever mission to touch the Sun. The mission broke records for fastest human-made object and closest approach to the Sun, and sent home its first light images including a picture of Earth in late October. Its first flight through the Suns outer atmosphere was on Nov. 7.
- After a two-year journey, NASAs Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission arrived at its destination, the asteroid Bennu, on Dec. 3. One of the first observations from NASAs first asteroid sample return mission revealed water locked inside the clays that make up Bennu.
- For only the second time in history, a human-made object reached the space between the stars. In December, NASA announced itsVoyager 2probe has exited the heliosphere the protective bubble of particles and magnetic fields created by the Sun.
- Using NASAs Hubble Space Telescope and ground-based observatories, astronomers found in June that Oumuamua, the first known interstellar object to travel through our solar system, had an unexpected speed boost and a change in trajectory. Scientists believe the object is a new type of comet.
- After nine years of searching for planets outside our solar system, NASAs Kepler space telescope ran out of fuel, but not before scientists were able to use it, and Hubble, to find hints of what could be a moon orbiting another planet outside our solar system. If confirmed, this would be the first exomoon ever detected.
- NASAs Transiting Exoplanet Survey Satellite (TESS), launched in April, continues the search for planets outside our solar system. The spacecraft, which began science operations in July, will survey the entire sky over the course of two years, searching for nearby exoplanets.
- NASAs Dawn mission, which launched in 2007, also ran out of fuel this year, but not before becoming the first spacecraft to orbit two separate bodies in the solar system the asteroid Vesta and dwarf planet Ceres. Among its many findings, Dawn helped scientists discover organics on Ceres and evidence that dwarf planets could have hosted oceans over a significant part of their history and may still.
- The Independent Review Board established by NASA to assess progress on its James Webb Space Telescope unanimously recommended this year that development on the worlds premier science observatory should continue. NASA established a new 2021 launch date for Webb, and completed several critical tests and milestones in 2018, including vibration and acoustic tests and a simulation of the telescopes complex communications. The two halves of Webb the spacecraft and the telescope were connected temporarily for a communications test during which they successfully spoke to each other.
- Newly analyzed data from NASAs Galileo spacecraft, collected two decades ago, indicate the magnetic field around the moon Ganymede makes it unlike any other in the solar system.
Humans in Space
In 2018, NASA astronauts Mark Vande Hei, Scott Tingle, Serena Aunon-Chancellor and Anne McClain participated in their first spaceflight missions to the International Space Station, benefitting from the experience of three veteran astronauts Joe Acaba, Ricky Arnold, and Drew Feustel, who also completed missions aboard the space station this year. Here are ways humans in space were leading discovery and improving life on Earth in 2018:
