  • How to Make Building Blocks for a Lunar Habitat
    The challenge of building habitats on the Moon is considerable, mainly because most additive manufacturing (aka. 3-D printing) techniques are not feasible. By utilizing a 3-D printing method known as light-based sintering, future missions to the Moon could manufacture bricks out of lunar regolith, rather than trying to build whole... Read more »
  • The Presence of Certain Minerals May Explain Why the Lunar Farside and Nearside are so Different
    Why does the Moon have two different faces?. That question frames the lunar dichotomy: The nearside that faces us is different than the lunar farside.

  • Reorienting MRO Massively Increases Its Subsurface Scanning Power
    Orientation is more important than most people thing when it comes to sensing. A common example would be when the lasers of a garage door are mis-aligned, forcing the door to remain open until they are brought back in line. But when it comes to scientific sensors, orientation is even... Read more »
  • Menstrual Cups Tested in Space Flight Conditions for the First Time
    For long-duration missions, female astronauts generally use hormonal contraception to suppress their periods. But this method has potential health risks and requires special storage. Pads and tampons create waste in space. Now researchers have tested menstrual cups on a sub-orbital rocket flight, where they experienced the force of launch, and... Read more »
