Oldest planetary debris in our galaxy found from new study
Write a comment
Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way. Their findings are published in the Monthly Notices of the Royal Astronomical Society, which conclude that a faint white dwarf located 90 light years from Earth, as Perseverance seals up Sample tube 14.

The team is making progress identifying and implementing a fix that will allow a seal to cap off the rover's latest rock sample, which was collected at the base of Jezero's delta from an outcrop called "Amalik." The anomaly first appeared on Oct. 5 after the successful coring of the mission's 14th sample, called "Mageik," when the seal assigned to cap the rock-core-filled sample tube did not rel University of Southern Queensland scientist unveils further proof of salty water on Mars

It may be known as a rocky, red planet but evidence is mounting that salty water exists at the base of polar deposits on Mars.
University of Southern Queensland's Professor Graziella Caprarelli is part of an international team investigating bright reflection signals below the Martian surface, first spotted in data acquired between 2010 and 2019 by the radar sounder MARSIS on board Mars Exp Martian Sausages: Sols 3641-3642

We are perched just below the "Marker Band," a thin dark band whose origin is unclear. As Michelle noted yesterday, we found some amazing textured float rocks in our workspace but were not in a good position to do contact science here, so we moved back a little in order to get it today.
These float rocks appear to have originated in the Marker Band, which can be seen running from lower lef Rocket Lab opens Archimedes Engine Test Stand at Stennis Space Center

Rocket Lab USA, Inc. (Nasdaq: RKLB) has kicked off operations for testing the Archimedes engine with a ribbon cutting ceremony at NASA's historic Stennis Space Center in Mississippi. The Archimedes Test Complex will be home to engine testing for the 165,000 lbf engines to be used on Rocket Lab's reusable Neutron rocket.
The Archimedes Test Complex is located across a 1 million square foot China's mightiest liquid-propellant rocket engine passes key test

Engineers in China's space industry conducted a key test of the country's most powerful liquid-propellant rocket engine on Saturday, marking a large stride in the development of a super-heavy carrier rocket.
Developed by the Academy of Aerospace Propulsion Technology in Xi'an of Shaanxi province, the 500-metric ton-thrust engine's first ignition test took place at the academy's testing fac Chinese rocket re-enters Earth atmosphere uncontrolled over the Pacific Ocean

Chinese rocket debris weighing 23 tons is crashing to Earth in an uncontrolled descent Friday.
U.S. Space Command tweeted a confirmation that the rocket re-entered the Earth's atmosphere over the south-central Pacific Ocean at 4:01 a.m. Friday.
The rocket was launched on Oct. 31 carrying the third and final module for the Tiangong space station. Much of the debris is expected to NASA rolls Artemis I mission rocket back to launch pad ahead of Nov. 14 launch

NASA is making another run at launching the Artemis I spacecraft on its maiden voyage to the moon, rolling the $4.1 billion rocket back onto the launch pad Thursday at Kennedy Space Center after months of delays pushed the liftoff to Nov. 14.
The launch is scheduled a week from Monday at 12:07 a.m., but NASA was keeping an eye on a low-pressure system in the Caribbean that threatened to Iran says it successfully tested satellite launcher

Iran announced Saturday the successful test flight of a rocket capable of propelling satellites into space, three months after launching a satellite with the help of Russia.
The United States has repeatedly voiced concern that such launches could boost Iran's ballistic missile technology, extending to the potential delivery of nuclear warheads.
But Iran insists it is not seeking nuclear Video: Testing Galileo for space
Write a comment
Galileo has grown to become Europe's single largest satellite constellation, and the world's most accurate satellite navigation system, delivering meter-level positioning to more than 3.5 billion users around the globe.
It all began at ESTEC's Test Center, Europe's largest satellite testing facility. This is where the very first positioning fix took place in March 2013, after the launch into orbit of the initial four IOV satellites. Following that, all 34 Galileo Full Operational Capability satellites also passed by ESTEC for their pre-flight testing.
This 3000 sq. m environmentally-controlled complex, operated and managed by European Test Services for ESA, hosts an array of test equipment able to simulate all aspects of spaceflight, from the noise and vibration of launch to the vacuum and temperature extremes of Earth orbit.
The production line at manufacturer OHB in Germany completed one new satellite every six weeks. After integration each satellite was then shipped to the ESTEC Test Center for a three-month test campaign, after which it would be accepted by the Agency and declared ready for flight. Some facilities have had to be adapted specifically for Galileo, and the ESTEC Test Center had to institute new security protocols because this was the first time that satellites with security restrictions were being tested at the site.
