China Satellite Navigation Conference to highlight digital economy, intelligent navigation
The 13th China Satellite Navigation Conference will be held in Beijing in May, highlighting the digital economy and intelligent navigation, according to the China Satellite Navigation Office. The conference will showcase the latest industrialization achievement of the BeiDou Navigation Satellite System (BDS), the office said. Diverse events such as summit forums, academic exchanges,
MAGIC telescopes observe nova explosion
Light on, light off - this is how one could describe the behavior of the nova, which goes by the name RS Ophiuchi (RS Oph). Every 15 years or so, a dramatic explosion occurs in the constellation of the Serpent Bearer. Birthplaces of a nova are systems in which two very different stars live in a parasitic relationship: A white dwarf, a small, burned-out and tremendously dense star - a teaspoon of
Webb will study formation, composition, clouds of distant worlds
The journey of commissioning the Webb telescope continues this week with the successful cooling of the Mid-InfraRed Instrument (MIRI), through the critical 'pinch point,' down to its final operating temperature of less than 7 kelvins (-447 degrees Fahrenheit, or -266 degrees Celsius). This was a precondition to completing the seventh and final stage of the mirror alignment process. The next step
Giant stars undergo dramatic weight loss program
Astronomers at the University of Sydney have found a slimmer type of red giant star for the first time. These stars have undergone dramatic weight loss, possibly due to the presence a greedy neighbour. Published in Nature Astronomy, the discovery is an important step forward to understanding the life of stars in the Milky Way - our closest stellar neighbours. There are millions of 'red gia
Most distant star to date spotted - but how much further back in time could we see?
The Hubble Space Telescope has observed the most distant star ever seen - Earendel, meaning morning star. Even though Earendel is 50 times the mass of the Sun, and millions of times brighter, we would not normally be able to see it. We can see it due to an alignment of the star with a large galaxy cluster in front of it whose gravity bends the light from the star to make it brighter and more foc
Sols 3444-3445: The curious case of cross-cutting ridges
Tosol's plan is focusing on examination of the linear ridges that cross-cut the local terrain. These raised ridges look like boxes with their lids cut off and mostly buried in the local bedrock, and all we can see are the vertical box faces sticking up out of the ground. How these structures actually form is an active area of investigation, and we hope the data we gather tosol will help us
Moon dust Neil Armstrong collected sells for more than $500,000
Moon dust Neil Armstrong collected in 1969 has sold for more than $500,000 at auction after NASA lost legal battles over its ownership. Five samples of the NASA-verified moon dust and the NASA container they're held in from the Apollo 11 mission sold for $504,375 on Wednesday, which was far below pre-auction estimate of between $800,000 and $1.2 million, according to the auction house Bonh
ReOrbit and TransAstra sign spacecraft development and logistics contracts
TransAstra, a provider of breakthrough orbital logistics and space domain awareness solutions, and ReOrbit, a provider of software-defined small satellites for beyond LEO missions, announced today that they have signed binding contracts for initial spacecraft development and orbital logistics services. Under these contracts, TransAstra will provide mission definition and engineering analys
NASA releases equity action plan to make space more accessible to all
In support of the Biden-Harris Administration's efforts to advance racial equity in the federal government, NASA has released its first-ever Equity Action Plan. The plan establishes key focus areas that will allow the agency to track progress toward improved diversity, equity, inclusion, and accessibility both internally and externally to NASA.
"At NASA, all of our missions depend on our steadfast commitment to equal opportunity," said NASA Administrator Bill Nelson. "The Equity Action plan deepens our commitment to further identify and remove the barriers that limit opportunity in underserved and underrepresented communities. This framework anchors fairness as a core component in every NASA mission to make the work we do in space and beyond more accessible to all."
The four focus areas the plan addresses are:
- Increasing integration and utilization of contractors and businesses from underserved communities and expanding equity in NASA's procurement process
- Enhancing grants and cooperative agreements to advance opportunities, access, and representation for underserved communities
- Leveraging Earth Science and socioeconomic data to help mitigate environmental challenges in underserved communities
- Advancing external civil rights compliance and expanding access to limited English proficient populations within underserved communities
NASA will lean into the focus areas by further analyzing and assessing feedback received from an initial request for information.
Video: Ariane 6 cryo-arms test mimics liftoff
Europe's Spaceport in French Guiana is preparing for the arrival of Ariane 6, ESA's new heavy-lift rocket. The latest round of testing aims to validate the system of fuel lines and mechanical supporting arms that will keep Ariane 6 topped up with liquid hydrogen and liquid oxygen in the critical moments before liftoff. This work is part of the final preparations of the new Ariane 6 launch complex and all the systems necessary for a launch.
With the mobile gantry fully retracted—as for a launch—two articulated arms attached to the upper part of the Ariane 6 mast on the launch pad were separated and retracted while filled with hydrogen that is cooled to its liquid state at cryogenic temperatures. This maneuver mimics the seconds before liftoff.
The "cryo-arms" are part of the fluidic connection system which connects to Ariane 6 in the final countdown to launch. They support the upper umbilicals which supply cryogenic top-up fuel, maintain the correct pressurization of the tanks, cool the engines before ignition and generally keep the upper stage in an optimal condition right up to the point of liftoff.
