40 Years Ago: Space Shuttle Atlantis Makes its Public Debut 

NASA - Breaking News - Mon, 03/10/2025 - 4:01pm

On March 6, 1985, NASA’s newest space shuttle, Atlantis, made its public debut during a rollout ceremony at the Rockwell International manufacturing plant in Palmdale, California. Under construction for three years, Atlantis joined NASA’s other three space-worthy orbiters, Columbia, Challenger, and Discovery, and atmospheric test vehicle Enterprise. Officials from NASA, Rockwell, and other organizations attended the rollout ceremony. By the time NASA retired Atlantis in 2011, it had flown 33 missions in a career spanning 26 years and flying many types of missions envisioned for the space shuttle. The Visitor Center at NASA’s Kennedy Space Center in Florida has Atlantis on display.

On Jan. 25, 1979, NASA announced the names of the first four space-worthy orbiters – Columbia, Challenger, Discovery, and Atlantis. Like the other vehicles, NASA named Atlantis after an historical vessel of discovery and exploration – the Woods Hole Oceanographic Institute’s two-masted research ship Atlantis that operated from 1930 to 1966. On Jan. 29, NASA signed the contract with Rockwell International of Downey, California, to build and deliver Atlantis. Construction began in March 1980 and finished in April 1984. Nearly identical to Discovery but with the addition of hardware to support the cryogenic Centaur upper stage then planned to deploy planetary spacecraft in 1986, plans shelved following the Challenger accident. After a year of testing, workers prepared Atlantis for its public debut.

Three days after the rollout ceremony, workers trucked Atlantis 36 miles overland to NASA’s Dryden, now Armstrong, Flight Research Center at Edwards Air Force Base in California’s Mojave Desert, for final preparations for its cross-country ferry flight. In the Mate Demate Device, workers placed Atlantis atop the Shuttle Carrier Aircraft, a modified Boeing 747, to begin the ferry flight. The duo left Edwards on April 12, the fourth anniversary of the first space shuttle flight. Following an overnight stop at Houston’s Ellington Air Force Base, now Ellington Field, Atlantis arrived at NASA’s Kennedy Space Center in Florida on April 13.

Four months later, on Aug. 12, workers towed Atlantis from the processing facility to the assembly building and mated it to an external tank and twin solid rocket boosters. The entire stack rolled out to Launch Pad 39A on Aug. 30 in preparation for the planned Oct. 3 launch of the STS-51J mission. As with any new orbiter, on Sept. 13 NASA conducted a 20-second Flight Readiness Firing of Atlantis’ three main engines. On Sept. 16, the five-person crew participated in a countdown demonstration test, leading to an on time Oct. 3 launch. Atlantis had joined the shuttle fleet and begun its first mission to space.

Over the course of its 33 missions spanning more than 26 years, Atlantis flew virtually every type of mission envisioned for the space shuttle, including government and commercial satellite deployments, deploying spacecraft to visit interplanetary destinations, supporting scientific missions, launching and servicing scientific observatories such as the Hubble Space Telescope, performing crew rotations and resupplying the Mir space station, and assembling and maintaining the International Space Station. Atlantis flew the final mission of the shuttle program, STS-135,  in July 2011. The following year, NASA transported Atlantis to the Kennedy Visitor Center for public display.

NASA received the upper stage for the agency’s Artemis II SLS (Space Launch System) rocket on Mar. 9 supplied by Boeing and United Launch Alliance (ULA). Known as the interim cryogenic propulsion stage, it arrived at the Multi Payload Processing Facility (MPPF) at NASA’s Kennedy Space Center in Florida.

The upper stage traveled to the spaceport from ULA’s Delta Operations Center at Cape Canaveral Space Force Station.

While at the MPPF, technicians will fuel the SLS upper stage with hydrazine for its reaction control system before transporting it to the center’s Vehicle Assembly Building for integration with SLS rocket elements atop mobile launcher 1. The rocket’s solid rocket booster segments are already assembled for launch and the core stage soon will be integrated, as will the launch vehicle stage adapter. The upper stage will be mated to the adapter.

The four-story propulsion system is powered by an RL10 engine, which will provide Orion with the boost it needs to orbit Earth twice before venturing toward the Moon.

NASA’s Dawn Sees Crescent Ceres

NASA’s Dawn spacecraft took this image of Ceres’ south polar region on May 17, 2017. Launched on Sept. 27, 2007, Dawn was NASA’s first truly interplanetary spaceship. The mission featured extended stays at two extraterrestrial bodies:  giant asteroid Vesta and dwarf planet Ceres, both in the debris-strewn main asteroid belt between Mars and Jupiter.

The spacecraft’s name was meant to present a simple view of the mission’s purpose: to provide information on the dawn of the solar system. The three principal scientific drivers for the mission were to capture the earliest moments in the origin of the solar system, determine the nature of the building blocks from which the terrestrial planets formed, and contrast the formation and evolution of two small planets that followed very different evolutionary paths.

Dawn completed the first order exploration of the inner solar system, addressed NASA’s goal of understanding the origin and evolution of the solar system, and complemented investigations of Mercury, Earth, and Mars. Dawn’s mission ended on Nov. 1, 2018, after two extended missions.

Follow Dawn’s journey from Earth to deep space through the words of mission director and chief engineer, Dr. Marc Rayman.

Finding White Dwarf-Main Sequence Binaries in Gaia Data with Machine Learning

Universe Today - Mon, 03/10/2025 - 1:19pm

Despite having recently officially ended its science operations in January, Gaia, one of the most prolific star explorers ever, is still providing new scientific insights. A recent paper pre-published on arXiv (which has not been peer-reviewed but was submitted to the Astrophysical Journal) took another look at some Gaia data to try to find a unique type of astronomical entity - white dwarf stars that are paired up in a binary with a main sequence one. By applying a machine learning technique called a "self-organizing map," they found 801 new white dwarf-main sequence (WDMS) binaries, increasing the total number ever found by over 20%.

Quantum Entaglement Sensors Could Test Quantum Gravity

Universe Today - Mon, 03/10/2025 - 12:03pm

Ask almost any physicist what the most frustrating problem is in modern-day physics, and they will likely say the discrepancy between general relativity and quantum mechanics. That discrepancy has been a thorn in the side of the physics community for decades. While there has been some progress on potential theories that could rectify the two, there has been scant experimental evidence to support those theories. That is where a new NASA Institute for Advanced Concepts grantee comes in - Selim Shahriar from Northwestern University, Evanston, was recently funded to work on a concept called the Space-borne Ultra-Precise Measurement of the Equivalent Principle Signature of Quantum Gravity (SUPREME-GQ), which he hopes will help collect some accurate experimental data on the subject once and for all.
