Outer solar system is more populated than previously thought, research reveals
Write a comment
Survey observations using the Subaru Telescope's ultra-widefield prime focus camera have revealed that there may be a population of small bodies further out in the Kuiper Belt waiting to be discovered.
The results, which are important for an understanding of the formation of the solar system, were obtained through an international collaboration between the Subaru Telescope and the New Horizons spacecraft traveling through the outer solar system.
NASA's New Horizons spacecraft was launched in 2006 with the critical mission of observing the surfaces of outer solar system bodies up close for the first time in human history; it successfully completed a flyby of the Pluto system in 2015, and in 2019 it made a flyby of one of the Kuiper Belt objects, (486958) Arrokoth.
There have been five spacecraft that have flown to the outer solar system (including New Horizons), but New Horizons is the only spacecraft that has flown through the Kuiper Belt while observing Kuiper Belt objects.
Gateway's propulsion system testing throttles up
Write a comment
The powerhouse of Gateway, NASA's orbiting outpost around the moon and a critical piece of infrastructure for Artemis, is in the midst of several electric propulsion system tests.
The Power and Propulsion Element (PPE), being manufactured by Maxar Technologies, provides Gateway with power, high-rate communications, and propulsion for maneuvers around the moon and to transit between different orbits.
The PPE will be combined with the Habitation and Logistic Outpost (HALO) before the integrated spacecraft's launch, targeted for late 2024 aboard a SpaceX Falcon Heavy. Together, these elements will serve as the hub for early Gateway crewed operations and various science and technology demonstrations as the full Gateway station is assembled around it in the coming years.
In this image, PPE engineers successfully tested the integration of Aerojet Rocketdyne's thruster with Maxar's power procession unit and Xenon Flow Controller.

Artemis IV: Gateway gadget fuels deep space dining
Write a comment
NASA engineers are working hard to ensure no astronaut goes hungry on the Artemis IV mission.
When international teams of astronauts live on Gateway, humanity's first space station to orbit the moon, they'll need innovative gadgets like the Mini Potable Water Dispenser.
Vaguely resembling a toy water soaker, it manually dispenses water for hygiene bags, to rehydrate food, or simply to drink. It is designed to be compact, lightweight, portable and manual, making it ideal for Gateway's relatively small size and remote location compared to the International Space Station closer to Earth.
A review of humanity's planned expansion between the Earth and the moon
Write a comment
Between low Earth orbit and the moon, there is a region of space measuring 384,400 km (238,855 mi) wide known as Cislunar space. In the coming decades, multiple space agencies will send missions to this region to support the development of infrastructure that will lead to a permanent human presence on the moon.
This includes orbital and surface habitats, landing pads, surface vehicles, technologies for in-situ resource utilization (ISRU), and other elements that will enable the long-term exploration and development of the lunar surface.
For all parties concerned, Cislunar space holds immense potential in terms of scientific, commercial, and military applications. The vastly increased level of activity on and around the moon makes space domain awareness (SDA)—knowledge of all operations within a region of space—paramount.
It is also necessary to ensure the continued success and utilization of the covered region.

Managing space debris through space law
Write a comment
It's becoming increasingly crowded in the orbits around Earth that are popular for space travel. And that's not just due to satellites—there's also more waste material, which is compromising safety. Ph.D. candidate Zhuang Tian is conducting research into the legal aspects of discarded space equipment. Whoever leaves debris behind should take responsibility and clean it up.
In the near future, probes with robotic arms will be hovering in orbit. The arms will have four metal tentacles spread out like a spider's legs, ready to catch a discarded satellite where the probes maneuver minutely. It's one of the techniques the company ClearSpace is currently simulating—only on Earth for the time being.
Active debris removal
With his specialization in space law, legal expert Zhuang Tian is following these developments closely. He will shortly be defending his Ph.D. thesis on the legal aspects of space debris disposal. The specific focus of his research is how companies like ClearSpace and the Japanese company Astroscale are planning on actively removing debris, because there is another option: space equipment that removes itself after use by burning into the atmosphere.
Boeing's beleaguered space capsule is heading back to Earth without two NASA astronauts

After months of turmoil over its safety, Boeing's new astronaut capsule is set to depart the International Space Station on Friday without its crew.
Video: Mars rover trials
Write a comment
Rover trials in a quarry in the U.K. showing a four-wheeled rover, known as Codi, using its robotic arm and a powerful computer vision system to pick up sample tubes.
The rover drives to the samples with an accuracy of 10 cm, constantly mapping the terrain. Codi uses its arm and four cameras to locate the sample tube, retrieve it and safely store it on the rover—all of it without human intervention.
At every stop, the rover uses stereo cameras to build up a 180-degree map of the surroundings and plan its next maneuvers. Once parked, the camera on top of the mast detects the tube and estimates its position with respect to the rover. The robotic arm initiates a complex choreography to move closer to the sample, fetch it and store it.
The sample tubes are a replica of the hermetically sealed samples inside which NASA's Perseverance rover is collecting precious Martian soil inside. To most people on Earth, they resemble lightsabers.
Two astronauts are left behind in space as Boeing's troubled capsule returns to Earth empty
Write a comment
Boeing's first astronaut mission ended Friday night with an empty capsule landing and two test pilots still in space, left behind until next year because NASA judged their return too risky.
Six hours after departing the International Space Station, Starliner parachuted into New Mexico's White Sands Missile Range, descending on autopilot through the desert darkness.
It was an uneventful close to a drama that began with the June launch of Boeing's long-delayed crew debut and quickly escalated into a dragged-out cliffhanger of a mission stricken by thruster failures and helium leaks.
Two NASA astronauts stuck in space have flown long missions before

The two NASA astronauts left behind at the International Space Station following the return of Boeing's troubled capsule are Navy test pilots who have ridden out long missions before.
Astronauts Butch Wilmore and Suni Williams are now full-time station crew members along with the seven others on board.
