A comprehensive research endeavor led by Heidelberg University and the GFZ German Research Centre for Geosciences Potsdam has shed new light on the causes of abrupt climate changes in ice ages. The study suggests that variations in summer insolation, or the amount of sunlight received, played a vital role in steering the shift between warm and cold phases during past ice ages.

NASA hears signal from Voyager 2 spacecraft after mistakenly cutting contact
Tuesday, 01 August 2023 16:16![NASA hears signal from Voyager 2 spacecraft after mistakenly cutting contact](https://scx1.b-cdn.net/csz/news/800a/2023/nasa-hears-signal-from.jpg "In this Aug. 4, 1977, photo provided by NASA, the "Sounds of Earth" record is mounted on the Voyager 2 spacecraft in the Safe-1 Building at the Kennedy Space Center, Fla., prior to encapsulation in the protective shroud. After days of silence, NASA has heard from Voyager 2, more than 12 billion miles away in interstellar space. Flight controllers accidentally sent a wrong command nearly two weeks ago that tilted the spacecraft's antenna away from Earth and severed contact.")

NASA listens for Voyager 2 spacecraft after wrong command cuts contact
Monday, 31 July 2023 19:50 Write a comment
NASA is listening for any peep from Voyager 2 after losing contact with the spacecraft billions of miles away.
Hurtling ever deeper into interstellar space, Voyager 2 has been out of touch ever since flight controllers accidentally sent a wrong command more than a week ago that tilted its antenna away from Earth. The spacecraft's antenna shifted a mere 2%, but it was enough to cut communications.
Although it's considered a long shot, NASA said Monday that its huge dish antenna in Canberra, Australia, is on the lookout for any stray signals from Voyager 2, currently more than 12 billion miles (19 billion kilometers) distant. It takes more than 18 hours for a signal to reach Earth from so far away.
In the coming week, the Canberra antenna—part of NASA's Deep Space Network—also will bombard Voyager 2's vicinity with the correct command, in hopes it hits its mark, according to NASA's Jet Propulsion Laboratory, which manages the Voyager missions.
Otherwise, NASA will have to wait until October for an automatic spacecraft reset that should restore communication, according to officials.

Could aging wine become the first major space manufacturing business?
Monday, 31 July 2023 18:01 Write a comment
In capitalist societies, resources are primarily directed at solving problems, and one of the biggest hurdles facing space development is its ability to directly solve the problems of the majority of humanity back on Earth. So far, we've taken some cautious commercial steps, primarily through satellite monitoring and communication technologies.
Some think that space tourism is the "killer app" that will kickstart the commercialization of space. But to really have a sustainable business model, humans need to make something in space that they are unable to make on Earth. This article is the first in a series where we will look at what those possible first manufactured goods are. And in this case, the good isn't something that might immediately be thought of as high-tech.
Wine is one of humanity's oldest products. We have been drinking it for thousands of years and likely will continue to do so for thousands more.
