During Cassini’s final days, mission team members from all around the world gathered at NASA’s Jet Propulsion Laboratory, Pasadena, California, to celebrate the achievements of this historic mission.

The four RS-25 engines fired for a little more than one minute and generated 1.6 million pounds of thrust. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon.

Outgoing NASA Associate Administrator for Communications Bettina Inclan (far right) hosts a press conference following the Green Run hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket on Saturday, January 16, 2021. Seated press conference participants included outgoing NASA Administrator Jim Bridenstine (center), Stennis Space Center Director Rick Gilbrech (left) and SLS Program Manager John Honeycutt from Marshall Space Flight Center. NASA conducted a hot fire test of the core stage’s four RS-25 engines on the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi. Scheduled for as long as eight minutes, the engines fired for a little more than one minute to generate a combined 1.6 million pounds of thrust, just as will occur during an actual launch. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the SLS core stage prior to launching the Artemis I mission to the Moon.

VANDENBERG AFB, Calif. -- During a news conference at Vandenberg Air Force Base, Calif. prior to the launch of NASA's Landsat Data Continuity Mission, or LDCM, media representative heard from Dr. Jim Irons, LDCM project scientist from NASA's Goddard Space Flight Center, Dr. Thomas Loveland, senior scientist and co-chair of the Landsat Science Team U.S. Geological Survey Earth Resources Observation and Science Center, and Kass Green, Landsat scientist and president of Kass Green and Associates. The Landsat Data Continuity Mission LDCM is the future of Landsat satellites. It will continue to obtain valuable data and imagery to be used in agriculture, education, business, science, and government. The Landsat Program provides repetitive acquisition of high resolution multispectral data of the Earth's surface on a global basis. The data from the Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space. It is a record unmatched in quality, detail, coverage, and value. Liftoff is planned for Feb. 11, 2013 aboard a United Launch Alliance Atlas V rocket.

CAPE CANAVERAL, Fla. – At NASA Headquarters in Washington and the Kennedy Space Center in Florida, NASA leaders spoke to members of the new media about how the first flight of the new Orion spacecraft is a first step in the agency's plans to send humans to Mars. Seen on a video monitor at Kennedy, Headquarter participants, from the left are: Trent Perrotto of NASA Public Affairs, Jason Crusan, director of Advanced Exploration Systems Division of Human Exploration and Operations Mission Directorate, Jim Reuther, deputy associate administrator for Programs, Space Technology Mission Directorate, and Jim Green, director of Planetary Division of the Science Mission Directorate. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted flight test of Orion is scheduled to launch Dec. 4, 2014 atop a United Launch Alliance Delta IV Heavy rocket, and in 2018 on NASA’s Space Launch System rocket.

CAPE CANAVERAL, Fla. – Engineers and technicians prepare NASA's Project Morpheus prototype lander for free flight test number 15 at the north end of the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. The lander will take off from the ground over a flame trench and use its autonomous landing and hazard avoidance technology, or ALHAT sensors, to survey the hazard field to determine safe landing sites. Project Morpheus tests NASA’s ALHAT and an engine that runs on liquid oxygen and methane, which are green propellants. These new capabilities could be used in future efforts to deliver cargo to planetary surfaces. Project Morpheus is being managed under the Advanced Exploration Systems, or AES, Division in NASA’s Human Exploration and Operations Mission Directorate.

CAPE CANAVERAL, Fla. - Construction of the Propellants North Administrative and Maintenance Facility begins in Launch Complex 39 at NASA's Kennedy Space Center in Florida. The facility will have a two-story administrative building to house managers, mechanics and technicians who fuel spacecraft at Kennedy adjacent to an 1,800-square-foot single-story shop to store cryogenic fuel transfer equipment. The new facility will feature high-efficiency roofs and walls, “Cool Dry Quiet” air conditioning with energy recovery technology, efficient lighting, and other sustainable features. The facility is striving to qualify for the U.S. Green Building Council’s Leadership in Energy and Environmental Design, or LEED, Platinum certification. If successful, Propellants North will be the first Kennedy facility to achieve this highest of LEED ratings after it is completed in the summer of 2010.

The canister will protect the RTG when it is moved. The RTG is the baseline power supply for the NASA’s New Horizons spacecraft, scheduled to launch in January 2006 on a journey to Pluto and its moon, Charon. As it approaches Pluto, the spacecraft will look for ultraviolet emission from Pluto's atmosphere and make the best global maps of Pluto and Charon in green, blue, red and a special wavelength that is sensitive to methane frost on the surface. It will also take spectral maps in the near infrared, telling the science team about Pluto's and Charon's surface compositions and locations and temperatures of these materials. When the spacecraft is closest to Pluto or its moon, it will take close-up pictures in both visible and near-infrared wavelengths. It is expected to reach Pluto in July 2015.

CAPE CANAVERAL, Fla. – Engineers and technicians prepare the launch pad for NASA's Project Morpheus prototype lander at the north end of the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. Morpheus is being prepared for free flight test number 15 at the SLF. The lander will take off from the ground over a flame trench and use its autonomous landing and hazard avoidance technology, or ALHAT sensors, to survey the hazard field to determine safe landing sites. Project Morpheus tests NASA’s ALHAT and an engine that runs on liquid oxygen and methane, which are green propellants. These new capabilities could be used in future efforts to deliver cargo to planetary surfaces. Project Morpheus is being managed under the Advanced Exploration Systems, or AES, Division in NASA’s Human Exploration and Operations Mission Directorate.
