NASA’s Psyche Mission on Track for Liftoff Next Month
Bound for a metal-rich asteroid of the same name, the Psyche mission is targeting Oct. 5 to launch from NASA’s Kennedy Space Center in Florida. The spacecraft’s solar arrays are folded like an envelope into their stowed position. Xenon gas – fuel for the journey to the asteroid belt – is loaded. All four thrusters have passed their final tests. Engineers have confirmed the massive high-gain antenna is set to transmit data. The software is tested and ready. The science instruments – a multispectral imager, magnetometer, and gamma-ray and neutron spectrometer – that will investigate the asteroid Psyche are poised for action. NASA’s Psyche spacecraft has less than 30 days to go before the opening of its launch period, which runs from Thursday, Oct. 5 through Wednesday, Oct. 25. What the mission learns from the metal-rich asteroid may tell us more about how planets form.

Hubble Sees Glittering Globular Cluster Embedded Inside Milky Way
This colorful image of the globular star cluster Terzan 12 is a spectacular example of how dust in space affects starlight coming from background objects. A globular star cluster is a conglomeration of stars, arranged in a spheroidal shape. Stars in globular clusters are bound together by gravity, with a higher concentration of stars towards the center. The Milky Way has about 150 ancient globular clusters at its outskirts. These clusters orbit around the galactic center, but far above and below the pancake-flat plane of our galaxy, like bees buzzing around a hive.
Lucy Spacecraft Captures its First Images of Asteroid Dinkinesh
The small dot moving against the background of stars is the first view from NASA’s Lucy spacecraft of the main belt asteroid Dinkinesh, the first of 10 asteroids that the spacecraft will visit on its 12-year voyage of discovery. Lucy captured these two images on Sept. 2 and 5, 2023. On the left, the image blinks between these first two images of Dinkinesh. On the right, the asteroid is circled to aid the eye. Lucy took these images while it was 14 million miles (23 million km) away from the asteroid, which is only about a half-mile wide (1 km). Over the next two months, Lucy will continue toward Dinkinesh until its closest approach of 265 miles (425 km) on Nov. 1, 2023. The Lucy team will use this encounter as an opportunity to test out spacecraft systems and procedures, focusing on the spacecraft’s terminal tracking system, designed to keep the asteroid within the instruments’ fields of view as the spacecraft flies by at 10,000 mph (4.5 km/s).

Here’s How Sept. 24 Asteroid Sample Delivery Will Work
Early morning on Sunday, Sept. 24, the OSIRIS-REx spacecraft’s sample capsule will come face-to-face with Earth’s atmosphere for the first time since the mission’s 2016 launch. On board are an estimated 8.8 ounces, or 250 grams, of rocky material collected from the surface of Bennu in 2020 – NASA’s first asteroid sample and the largest ever collected in space. When it approaches Earth, the OSIRIS-REx spacecraft won’t slow down as it makes its sample drop-off. Instead, when it reaches 63,000 miles (or 102,000 kilometers) above Earth’s surface – about one-third the distance from Earth to the Moon – a message from operators on the ground will trigger the capsule’s release and the capsule will be sent spinning toward the atmosphere below. Twenty minutes after the drop-off, the spacecraft will fire its thrusters to divert past Earth toward asteroid Apophis, where it will continue investigating our solar system under a new name: OSIRIS-APEX (OSIRIS-Apophis Explorer).

NASA’s Oxygen-Generating Experiment MOXIE Completes Mars Mission
Riding with the Perseverance rover, the instrument has proved to be a viable technology for astronauts on Mars to produce oxygen for fuel and breathing. When the first astronauts land on Mars, they may have the descendants of a microwave-oven-size device to thank for the air they breathe and the rocket propellant that gets them home. That device, called MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment), has generated oxygen for the 16th and final time aboard NASA’s Perseverance rover. After the instrument proved far more successful than its creators at the Massachusetts Institute of Technology (MIT) expected, its operations are concluding.
