Launching this summer, NASA’s Laser Communications Relay Demonstration (LCRD) will showcase the dynamic powers of laser communications technologies. With NASA’s ever-increasing human and robotic presence in space, missions can benefit from a new way of “talking” with Earth.

Since the beginning of spaceflight in the 1950s, NASA missions have leveraged radio frequency communications to send data to and from space. Laser communications, also known as optical communications, will further empower missions with unprecedented data capabilities.

Great new episode with renowned geneticist Christopher Mason who talks about his book on how we will need to bioengineer our own species in order to expand beyond our solar system.

Geneticist Christopher Mason chats about his new book, “The Next 500 Years: Engineering Life to Reach New Worlds” from MIT Press. We discuss both the nuts and bolts and the philosophy driving our expansion offworld. Mason’s goal is to preserve our species by expanding to an Earth 2.0 in order to avoid our star’s own Red Giant endgame.

China’s plucky Yutu 2 rover is about to wake up and continue to explore the far side of the moon as the nation works to land a rover on Mars this May.

The rover, which launched with the Chang’e 4 mission, landed on the far side of the moon in January 2019 and recently completed its 29th lunar day of activities, the China Lunar Exploration Project (CLEP) said on April 23.

In the sparse collection of atoms that fills interstellar space, Voyager 1 has measured a long-lasting series of waves where it previously only detected sporadic bursts.

Until recently, every spacecraft in history had made all of its measurements inside our heliosphere, the magnetic bubble inflated by our Sun. But on August 25, 2012, NASA ’s Voyager 1 changed that. As it crossed the heliosphere’s boundary, it became the first human-made object to enter – and measure – interstellar space. Now eight years into its interstellar journey, a close listen of Voyager 1’s data is yielding new insights into what that frontier is like.

Physicists have measured the “skin” of an atom for the first time and, perhaps unsurprisingly, it is extremely thin. The measurement may help us understand the properties of neutron stars.

Lead-208, an isotope that contains 82 protons and 126 neutrons, has a type of nucleus that physicists refer to as “doubly magic” because both the protons and the neutrons are arranged neatly into shells inside the nucleus. These shells keep the atom relatively stable and make it simpler to experiment on, so when the PREX collaboration at the Thomas Jefferson National Accelerator Facility in Virginia set out to measure neutron skin, they opted to experiment on lead-208.

Within the Milky Way, there are an estimated 200 to 400 billion stars, all of which orbit around the center of our galaxy in a coordinated cosmic dance. As they orbit, stars in the galactic disk (where our Sun is located) periodically shuffle about and get closer to one another. At times, this can have a drastic effect on the star that experience a close encounter, disrupting their systems and causing planets to be ejected.

Knowing when stars will make a close encounter with our Solar System, and how it might shake-up objects within it, is therefore a concern to astronomers. Using data collected by the Gaia Observatory, two researchers with the Russian Academy of Sciences (RAS) determined that a handful of stars will be making close passes by our Solar System in the future, one of which will stray pretty close!

The study was conducted by Vadim V. Bobylev and Anisa T. Bajkova, two researchers from the Pulkovo Observatory’s Laboratory of Galaxy Dynamics in St. Petersburg, Russia. As they indicated, they relied on astrometric data from the Gaia mission’s Early Data Release 3 (EDR3), which revealed kinematic characteristics of stars that are expected to pass within 3.26 light-years (1 Parsec) with the Solar System in the future.

NASA’s newest Mars rover is beginning to study the floor of an ancient crater that once held a lake.

NASA’s Perseverance rover has been busy serving as a communications base station for the Ingenuity Mars Helicopter and documenting the rotorcraft’s historic flights. But the rover has also been busy focusing its science instruments on rocks that lay on the floor of Jezero Crater.

What insights they turn up will help scientists create a timeline of when an ancient lake formed there, when it dried, and when sediment began piling up in the delta that formed in the crater long ago. Understanding this timeline should help date rock samples – to be collected later in the mission – that might preserve a record of ancient microbes.

Scientists have spotted water in a primitive meteorite, expanding our understanding of the ancient solar system.
