Masten XL-1 landing

WASHINGTON — Masten Space Systems is pushing back the launch of its first lunar lander mission by nearly a year, the latest in a series of delays by companies with NASA contracts to transport payloads to the moon.

Simulating the burn-up during atmospheric reentry of one of the bulkiest items aboard a typical satellite using a plasma wind tunnel.

This Solar Array Drive Mechanism (SADM) has the essential task of keeping a satellite's solar wings trained on the Sun, maintaining mission operations.

But its bulky nature presents a problem in terms of space debris guidelines. When a reenters on an uncontrolled basis, the spacecraft operator has to prove that the on-ground casualty risk posed by its satellite is lower than 1 in 10 000.

So last year SADM manufacturer Kongsberg Defense & Aerospace (KDA) started an investigation supported by ESA, Hyperschall Technologie Göttingen GmbH (HTG) and the German Aerospace Center (DLR) to demonstrate the 'desmisability' of one of its products.

They began by modeling such a reentry using ESA's dedicated SCARAB (Spacecraft Atmospheric Reentry and Aerothermal Break-up) software and comparable resources, tweaking the SADM by switching one screw to lower-melting-point alumimium to promote an earlier, higher-altitude breakup.

Image: Jezero Crater’s "Delta Scarp"
Composed of five images, this mosaic of the Jezero Crater's "Delta Scarp" was taken on March 17, 2021, by the Remote Microscopic Imager (RMI) camera aboard NASA's Perseverance rover from 1.4 miles (2.25 kilometers) away. Scientists believe the 377-foot-wide (115-meter-wide) escarpment is a portion of the remnants of a fan-shaped deposit of sediments that resulted from the confluence between an ancient river and an ancient lake.

Less metals, more X-rays!
Α Hubble Space Telescope image of the galaxy NGC 922, showing the regions with intense star formation (red colour). The purple contours show the X-ray emission, based on observations with the Chandra X-ray Observatory. The location of the bright ULXs is indicated by the circles, that occupy regions of intense star-forming activity.

A recent article published in the Monthly Notices of the Royal Astronomical Society, led by Dr. Kostas Kouroumpatzakis, of the Institute of Astrophysics at the Foundation for Research and Technology, Hellas (IA-FORTH), and the University of Crete, provides new insights into the connection between the X-ray luminosity of accreting black holes and neutron stars and the composition of the stellar populations they are associated with.

SAN FRANCISCO – The Space Information Sharing and Analysis Center (ISAC) welcomed its newest member, Microsoft, June 23 with an announcement highlighting the tech giant’s cybersecurity expertise.

“Space cybersecurity is relatively unknown territory because we’re approaching and doing some things for the first time, fortunately through Space ISAC we have the opportunity to build a foundation for protection from a knowledge pool with deep security expertise,” Frank Backes, chair of the Space ISAC board of directors and Kratos Space Federal senior vice president, said in a statement.

Microsoft is staking its claim on the space sector.

In the last year alone, the tech giant unveiled Azure Orbital, a service to move data from satellites into the cloud, and mobile cloud computing data centers for SpaceX’s Starlink constellation in low Earth orbit (LEO) and SES’ O3b medium Earth orbit (MEO) constellations.

TAMPA, Fla. — Satellite propulsion startup Benchmark Space Systems has secured customers for a new ‘mobility-as-a-service’ business, which similar to a taxi ride will charge them based on the amount of propellant they use.

Burlington, Vermont-based Benchmark said its in-space mobility service significantly reduces upfront propulsion costs for on-orbit servicing, assembly and manufacturing (OSAM) ventures with indefinite propulsion needs.
