  Washington DC (UPI) Apr 23, 2021 Proliferating levels of debris are posing a threat to the space environment and should be regulated as more satellites are being launched into space, researchers say. Edinburgh University researchers said in a study published Friday in the journal Nature Astronomy the debris is troublesome, potentially affecting "professional astronomy, public stargazing and the cultural importance of the sky" to indigenous populations. The situation can also damage "the sustainability of commercial, civ ... read more |

Due to some complex terrain, the rover's last drive came up about ten meters short of the target destination. The rover's unexpected parking orientation unfortunately will not allow our usual uplink direct from Earth.
We can instead send the weekend's commands through one of the orbiters at Mars, but a little later than planned. As a result, today's plan had to be adjusted accordingly. Wee ... more |

In 2006, the Cassini spacecraft recorded geyser curtains shooting forth from "tiger stripe" fissures near the south pole of Saturn's moon Enceladus - sometimes as much as 200 kilograms of water per second. A new study suggests how expanding ice during millennia-long cooling cycles could sometimes crack the moon's icy shell and let its inner ocean out, providing a possible explanation for the gey ... more |
