How are stars born, and how do they die? How do they produce the energy that keeps them burning for billions of years? How do they create the elements we observe today? Definitive answers to these questions continue to elude scientists in their quest to understand the processes that shape the chemical makeup of the universe. Although the exact details of the reaction processes are unclear,

A previously unpublished manuscript by Apollo 14 Astronaut Edgar Mitchell, stored in a bank vault for nearly four decades, has now been made available by Pen-L Publishing. This manuscript draws critical comparisons between the growing militarization of space and present-day realities, raising concerns over the increasing potential for nuclear conflict in space. Mitchell's work explores the

The ATLID atmospheric lidar, the final instrument aboard the EarthCARE satellite launched in May, has now been successfully activated. EarthCARE, a joint mission by the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), aims to provide more precise measurements of clouds, aerosols, and radiation. Researchers from the Leibniz Institute for Tropospheric Research (

There are plenty of uses for powerful lasers in space. But where should we put them?
Recently, Astronomers spotted three near-Earth asteroids (NEAs) hiding in the glare of the Sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object that is potentially hazardous to Earth to be discovered in the last eight years.

Reinventing the clock: NASA's new tech for space timekeeping

Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellites to pinpoint locations. Three teams at NASA's Goddard Space Flight Center in Greenbelt, Maryland, are at work to push timekeeping for space exploration to new levels of precision.

  • One team develops highly precise quantum clock synchronization techniques to aid essential spacecraft communication and navigation.
  • Another Goddard team is working to employ the technique of clock synchronization in space-based platforms to enable telescopes to function as one enormous observatory.
  • The third team is developing an for spacecraft based on strontium, a metallic chemical element, to enable scientific observations not possible with current technology.

There could be a way to fix spacecraft at L2, like Webb and Gaia

Billions of dollars of observatory spacecraft orbit around Earth or in the same orbit as our planet. When something wears out or goes wrong, it would be good to be able to fix those missions "in situ." So far, only the Hubble Space Telescope (HST) has enjoyed regular visits for servicing.

What if we could work on other telescopes "on orbit?" Such "fixit" to other facilities are the subject of a new NASA paper investigating optimal orbits and trajectories for making service calls on telescopes far beyond Earth.
