The test version of a unique satellite navigation receiver has been delivered for integration testing on the Lunar Pathfinder spacecraft. The NaviMoon satnav receiver is designed to perform the farthest ever positioning fix from Earth, employing signals that will be millions of times fainter than those used by our smartphones or cars.

A bright fireball was observed by a network of all-sky cameras across southern Ontario at 11:37pm on Sunday, April 17, 2022. Analysis of the video data suggests that fragments of the meteor are likely to have made it to the ground near the eastern shore of Lake Simcoe, just north of the town of Argyle.

A SpaceX Falcon 9 rocket launched from Cape Canaveral Space Force Station in Florida on Thursday, carrying another 53 Starlink Internet satellites into space.
The rocket lifted off at 1:51 p.m. from Launch Complex 40 after a 3-hour delay due to strong winds. It was the 43rd launch related to the Starlink project.

Friday, 22 April 2022 10:02
Mercury harbors water ice in the shadows of the steepest craters around its poles. But it is unclear how those water molecules ended up on Mercury. Now a new simulation shows that incoming minor bodies such as asteroids, comets and dust particles carry enough water to account for all the ice sheets present. The study could form the basis for new research on water in exoplanetary systems. Publica Black holes raze thousands of stars to fuel growth

NASA's Lucy mission is a 'go' for solar array deployment attempt
Thursday, 21 April 2022 20:11
On April 18, NASA decided to move forward with plans to complete the deployment of the Lucy spacecraft's stalled, unlatched solar array. The spacecraft is powered by two large arrays of solar cells that were designed to unfold and latch into place after launch. One of the fan-like arrays opened as planned, but the other stopped just short of completing this operation.
Through a combination of rigorous in-flight solar array characterization and ground testing, Lucy engineers determined the unlatched solar array is nearly fully open, positioned at approximately 345 out of the full 360 degrees, and is producing ample energy for the spacecraft. Nonetheless, the team is concerned about potential damage to the array if the spacecraft conducts a main engine burn in its present configuration.
After launch, the arrays were opened by a small motor that reels in a lanyard attached to both ends of the folded solar array. The team estimates that 20 to 40 inches of this lanyard (out of approximately 290 inches total) remains to be retracted for the open array to latch.
The solar array was designed with both a primary and a backup motor winding to give an added layer of reliability for the mission-critical solar array deployment.
