NASA has stacked the first piece of the Space Launch System (SLS) rocket on the mobile launcher in preparation for the Artemis I launch next year. At NASA’s Kennedy Space Center in Florida, engineers lowered the first of 10 segments into place Nov. 21 for the twin solid rocket boosters that will power the first flight of the agency’s new deep space rocket. Artemis I will be an uncrewed flight to test the SLS rocket and Orion spacecraft as an integrated system ahead of crewed flights to the Moon with the Artemis program.

Rocket off course? It could be a slosh problem.
Propellant slosh, to be exact. The motion of propellant inside a rocket-based launch vehicle or spacecraft tank is an ever-present, vexing problem for spaceflight. Not only can it make gauging the amount of available propellant difficult, but the volatile waves of liquid can literally throw a rocket off its trajectory.
HUNTSVILLE, Ala. (NASA PR) — Flying silently through the void of space around a globe of blue and green is the most advanced science laboratory ever developed: the International Space Station. Inside humanity’s orbiting outpost is a buzz of activity as explorers, pilots, doctors, and scientists from around the world conduct experiments, maintain the facility, and develop new technologies.
La Grange Park, Ill. (American Nuclear Society PR) — NASA aims to develop nuclear technologies for two space applications: propulsion and surface power. Both can make planned NASA missions to the moon more agile and more ambitious, and both are being developed with future crewed missions to Mars in mind. Like advanced reactors here on Earth, space nuclear technologies have an accelerated timeline for deployment in this decade.
GREENBELT, Md. (NASA PR) — NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission has successfully stowed the spacecraft’s Sample Return Capsule (SRC) and its abundant sample of asteroid Bennu. On Wednesday, Oct. 28, the mission team sent commands to the spacecraft, instructing it to close the capsule – marking the end of one of the most challenging phases of the mission.
GREENBELT, Md. (NASA PR) — NASA’s OSIRIS-REx mission is ready to perform an early stow on Tuesday, Oct. 27, of the large sample it collected last week from the surface of the asteroid Bennu to protect and return as much of the sample as possible.
On Oct. 22, the OSIRIS-REx mission team received images that showed the spacecraft’s collector head overflowing with material collected from Bennu’s surface – well over the two-ounce (60-gram) mission requirement – and that some of these particles appeared to be slowly escaping from the collection head, called the Touch-And-Go Sample Acquisition Mechanism (TAGSAM).
HUNTSVILLE, Ala. (NASA PR) — NASA’s Human Landing System (HLS) Program recently checked off a key milestone in its progress toward landing the first woman and the next man on the Moon by 2024. The HLS Program conducted Certification Baseline Reviews (CBR) with the three U.S. companies competing to provide landers that will deliver Artemis astronauts to the Moon. These virtual meetings were the culmination of critical work by NASA and the companies since NASA announced the base period selections in April.
GREENBELT, Md. (NASA PR) — NASA’s first mission to return a sample from an ancient asteroid arrived at its target, the asteroid Bennu, on Dec. 3, 2018. This mission, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer, or OSIRIS-REx, is a seven-year long voyage set to conclude upon the delivery to Earth of at least 2.1 ounces (60 grams) and possibly up to almost four and a half pounds (two kilograms) of sample.
It promises to be the largest amount of extraterrestrial material brought back from space since the Apollo era. The 20-year anniversary of the asteroid’s discovery was in September 2019 — and scientists have been collecting data ever since. Here’s what we already know (and some of what we hope to find out) about this pristine remnant from the early days of our solar system.
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) — The process of building landing pads, habitats, and roads on the Moon will likely look different than the common construction site on Earth. Excavation robots, for one, will need to be lightweight yet capable of digging in reduced gravity. A large-scale construction system could be autonomous and equipped to work without astronauts’ help.
HUNTSVILLE, Ala. (NASA PR) — NASA’s Watts on the Moon Challenge — the agency’s newest public prize competition — is now open and accepting submissions. NASA invites innovative minds from across the United States to provide ideas for sustainable energy storage, distribution, and management on the lunar surface.
As part of the Artemis program, NASA will send astronauts to new areas of the Moon including the lunar South Pole, and prepare for human exploration of Mars. As noted in the agency’s recent lunar surface report, sustainable missions will require an unprecedented capacity for power. Astronauts will need a continuous supply of power from multiple sources to live and work on the Moon for long periods. A flexible and robust system for surface power is key to safe and robust lunar exploration.
KENT, Wash. (Blue Origin PR) — The Human Landing System (HLS) National Team, led by Blue Origin with partners Lockheed Martin, Northrop Grumman, and Draper, has completed its System Requirements Review (SRR). SRR is the first program “gated milestone,” which marks the successful baselining of the requirements for the mission, space vehicles, and ground segment. The design proceeded to the NASA Certification Baseline Review (CBR), followed by the lower-level element SRRs, and the preliminary design phase.
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.
WASHINGTON (NASA PR) — Kathy Lueders, NASA’s associate administrator for Human Exploration and Operations, has named Robyn Gatens as acting director of the International Space Station at NASA Headquarters. The appointment was effective Aug. 25. Sam Scimemi, the former director, has assumed new responsibilities as a special assistant for the agency’s Human Exploration and Operations Mission Directorate.
“Robyn has demonstrated her leadership and strategic vision for the International Space Station and our efforts to enable a robust low-Earth orbit economy, and I am confident she will continue to do so as acting director,” said Lueders.
HAMPTON, Va. (NASA PR) — NASA is developing next-generation small rocket engines to help reduce the cost of NASA and commercial spacecraft destined for the Moon, Mars, and beyond.
NASA’s Thruster for the Advancement of Low-temperature Operation in Space (TALOS) project is developing small thrusters to reduce overall spacecraft mass and power, which will reduce mission costs. The thrusters can make alterations in a spacecraft’s flight path or altitude and can be used to enter orbit and descend to the surface of another world. They can also serve as main propulsion thrusters for landers.
