Exoplanet surveyor Ariel passes major milestone

Ariel, ESA’s next-generation mission to observe the chemical makeup of distant exoplanets, has passed a major milestone after successfully completing its payload Preliminary Design Review (PDR).
The Universe in a box: preparing for Euclid’s survey

ESA’s Euclid mission will create a 3D-map of the Universe that scientists will use to measure the properties of dark energy and dark matter and uncover the nature of these mysterious components. The map will contain a vast amount of data, it will cover more than a third of the sky and its third dimension will represent time spanning 10 billion years of cosmic history.
But dealing with the huge and detailed set of novel data that Euclid observations will produce is not an easy task. To prepare for this, scientists in the Euclid Consortium have
Chemical contamination on International Space Station is out of this world, study shows

Concentrations of potentially harmful chemical compounds in dust collected from air filtration systems on the International Space Station (ISS) exceed those found in floor dust from many American homes, a new study reveals.
In the first study of its kind, scientists analyzed a sample of dust from air filters within the ISS and found levels of organic contaminants which were higher than the median values found in US and Western European homes.
Publishing their results in Environmental Science & Technology Letters, researchers from the University of Birmingham, UK, as well as the NASA Glenn Research Center, U.S., say their findings could guide the design and construction of future spacecraft.
Contaminants found in the "space dust" included polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCDD), "novel" brominated flame retardants (BFRs), organophosphate esters (OPEs), polycyclic aromatic hydrocarbons (PAH), perfluoroalkyl substances (PFAS), and polychlorinated biphenyls (PCBs).
BFRs and OPEs are used in many countries to meet fire safety regulations in consumer and commercial applications like electrical and electronic equipment, building insulation, furniture fabrics and foams.
PAH are present in hydrocarbon fuels and emitted from combustion processes, PCBs were used in building and window sealants and in electrical equipment as dielectric fluids, while PFAS have been used in applications like stain proofing agents for fabrics and clothing.

NASA's Ingenuity Mars helicopter flies again after unscheduled landing

NASA's Ingenuity Mars Helicopter successfully completed its 54th flight on Aug. 3, the first flight since the helicopter cut its July 22 flight short. The 25-second up-and-down hop provided data that could help the Ingenuity team determine why its 53rd flight ended early.
Flight 53 was planned as a 136-second scouting flight dedicated to collecting imagery of the planet's surface for the Perseverance Mars rover science team.
How to change an asteroid into a space habitat, in just 12 years

The basic idea of turning an asteroid into a rotating space habitat has existed for a while. Despite that, it's always seemed relatively far off regarding technologies, so the concept hasn't received much attention over the years. But, if you're retired and have an underlying interest in researching space habitats, developing a detailed plan for turning an asteroid into one seems like a great use of time.
And that is precisely what David W. Jensen, a retired Technical Fellow at Rockwell Collins, recently did. He released a 65-page paper on the arXiv preprint server that details an easy-to-understand, relatively inexpensive, and feasible plan to turn an asteroid into a space habitat.
