The Moon Is Rusting, and Researchers Want to Know Why

While our Moon is airless, research indicates the presence of hematite, a form of rust that normally requires oxygen and water. That has scientists puzzled.

PASADENA, Calif. (NASA PR) — Mars has long been known for its rust. Iron on its surface, combined with water and oxygen from the ancient past, give the Red Planet its hue. But scientists were recently surprised to find evidence that our airless Moon has rust on it as well.

A new paper in Science Advances reviews data from the Indian Space Research Organization’s Chandrayaan-1 orbiter, which  discovered water ice and mapped out a variety of minerals while surveying the Moon’s surface in 2008.

GAO: NASA Performance on Major Projects Continues to Deteriorate

The Government Accountability Office (GAO) released its latest assessment of NASA’s major projects at the end of April. It found that NASA’s performance on its major projects continued to deteriorate on cost and schedule. (Full Report)

Below are key excerpts from the report that provide an overview of where NASA stands on its major projects. Although GAO did not analyze the Artemis program to return astronauts to the moon, the watchdog warned the Trump Administration’s decision to move the landing date up from 2028 to 2024 will put more pressure on the space agency.

“Looking ahead, NASA will continue to face significant cost and schedule risks as it undertakes complex efforts to return to the moon under an aggressive time frame,” the report stated.

Whether it stays that way depends upon what happens between now and its planned launch aboard an Indian booster in September 2022.
