New approach could take space missions to new heights
Write a comment
New Curtin University research could change how space missions are conducted and lead to improvements in industries as diverse as environmental management, agriculture, disaster management and infrastructure inspection.
A team from Curtin's School of Earth and Planetary Sciences has developed a breakthrough in operating and monitoring small satellites, known as CubeSats.
The project saw new algorithms created to use links between satellites to precisely determine a CubeSat's position, whether flying individually or in formation.
Project lead Professor Ahmed El-Mowafy said the new approach overcomes many of the constraints faced when using CubeSats, such as their small size and changes in aerodynamic forces affecting their orbits.
"These new methods mean CubeSats can now operate more independently, without the need for constant human control," Professor El-Mowafy said.
"When human control is needed, the CubeSats are simpler to manage and can be guided and controlled in real time—making them far more efficient to use in space missions.
"We can now operate them and be precise down to a few centimeters, which is a huge improvement on the previous accuracy level of several meters.
NASA cancels spacewalk at ISS over 'spacesuit discomfort issue'
Write a comment
A spacewalk scheduled for two astronauts outside the International Space Station was canceled by NASA about an hour before it was to begin Thursday morning.
"The spacewalk today, June 13, at the International Space Station did not proceed as scheduled due to a spacesuit discomfort issue," NASA said on its blog. No other details were immediately given.
"The spacewalk today, June 13, with NASA astronauts Tracy C. Dyson and Matt Dominick at the International Space Station will not be proceeding as scheduled," NASA said.
NASA said Tracy C. Dyson and Matt Dominick, the astronauts scheduled for the space walk, started taking off their spacesuits at approximately 7:25 am EDT, about an hour before the crew was anticipated to exit the ISS through an airlock.
Dyson and Dominick's spacewalk was supposed to include station maintenance and science work.
In announcing the spacewalk, NASA said two astronauts would remove some communications equipment from one of the ISS's laboratory modules with assistance from a robotic arm on the station. Dyson and Dominick were also going to swab surfaces on the ISS to "determine if microorganisms released through station vents can survive the external microgravity environment.
Space weather forecasting needs an upgrade to protect future Artemis astronauts

NASA has set its sights on the moon, aiming to send astronauts back to the lunar surface by 2026 and establish a long-term presence there by the 2030s. But the moon isn't exactly a habitable place for people.
Cosmic rays from distant stars and galaxies and solar energetic particles from the sun bombard the surface, and exposure to these particles can pose a risk to human health.
Both galactic cosmic rays and solar energetic particles, are high-energy particles that travel close to the speed of light.
While galactic cosmic radiation trickles toward the moon in a relatively steady stream, energetic particles can come from the sun in big bursts. These particles can penetrate human flesh and increase the risk of cancer.
Earth has a magnetic field that provides a shield against high-energy particles from space. But the moon doesn't have a magnetic field, leaving its surface vulnerable to bombardment by these particles.
First Camera Integrated for Plato Exoplanet Explorer
Write a comment
The integration of Plato's cameras has commenced at OHB's Space Centre and Optics facility in Oberpfaffenhofen, Germany. The first of 26 cameras has been successfully attached to Plato's optical bench, ensuring precise alignment for the mission.
"Plato will use 24 'normal' cameras and 2 'fast' cameras to look at more than 100 000 stars and search for planets around them." The mission uses NASA Selects Proposals for Space Weather Study

NASA has selected three proposals for concept studies of missions to investigate the complex system of space weather that surrounds our planet and its connection to Earth's atmosphere.
The three concepts propose how to implement the DYNAMIC (Dynamical Neutral Atmosphere-Ionosphere Coupling) mission, recommended by the 2013 Decadal Survey for Solar and Space Physics. The DYNAMIC mission aim Hughes Europe Enters Defense and Government Markets with Konnect VHTS Services

Hughes Europe, a subsidiary of Hughes Network Systems, LLC, an EchoStar company (Nasdaq: SATS), announces its strategic expansion into the military, defense, and government sectors across pan-European nations. Troy Truman has joined Hughes and will act as the head of this initiative.
The initiative will meet the increasing demand for high-speed connectivity and the growing security concern Hera and its CubeSats speak with mission control
Write a comment
ESA’s Hera asteroid mission and its two CubeSats interacted as if they were in space, within the foam pyramid-lined walls of the Agency’s Maxwell test chamber in the Netherlands. The trio communicated together, sharing data and ranging information at the same time as their Hera mothership received commands from its mission controllers at the European Space Operations Centre in Darmstadt, Germany.
