It’s Time to Give the Moon Its Own Time

Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom. However, according to Einstein’s theory of general relativity, mass slows down these oscillations, making time appear to move more slowly for objects in large gravity wells. This distinction becomes critical as we start considering how to keep track of time between two separate gravity wells of varying strengths, such as on the Earth and the Moon. A new paper by Pascale Defraigne at the Royal Observatory of Belgium and her co-authors discusses some potential frameworks for solving that problem and settles on using the new Lunar Coordinate Time (TCL) suggested by the International Astronomical Union (IAU).

‘Uncontrolled experiment:’ Study links harmful atmospheric metals to spacecraft reentry

GOLDEN, CO — The surge in megasatellite constellations is creating problems beyond amplifying the Earth-circling space debris, according to new research. Reentering spacecraft and rocket stages may also be damaging Earth’s atmosphere, as well as increasing the risk of space waste hitting the Earth. New research posted to the preprint database ArXiv finds that “space […] The post ‘Uncontrolled experiment:’ Study links harmful atmospheric metals to spacecraft reentry appeared first on SpaceNews.

Lux Aeterna nets US government partnerships for reusable satellite technology

Ground truth: Why the lunar program needs its Earthbound network

As the world prepares to return to the moon, much of the attention remains fixed on the visible frontier: the rockets, landers and orbital stations that will make it possible. Yet the success of this new era in exploration depends on something far less visible — the communications infrastructure that keeps those missions alive once […] The post Ground truth: Why the lunar program needs its Earthbound network appeared first on SpaceNews.

An explosion 92 million miles away just grounded Jeff Bezos’ New Glenn rocket

CAPE CANAVERAL, Florida—The second flight of Blue Origin’s New Glenn rocket was postponed again Wednesday as a supercharged wave of magnetized plasma from the Sun enveloped the Earth, triggering colorful auroral displays and concerns over possible impacts to communications, navigation, and power grids. Solar storms like the one this week can also affect satellite operations. That is the worry that caused NASA to hold off on launching a pair of science probes from Cape Canaveral Continue ReadingAn explosion 92 million miles away just grounded Jeff Bezos’ New Glenn rocket
