Cosmic Spotlight

NASA conducted the first-ever test of a lithium-fed nuclear thruster, bringing a novel propulsion concept to life in the lab. The thruster uses nuclear power to heat and expel lithium propellant, promising greater efficiency for long-duration space travel. This could significantly shorten the time required for missions to Mars. The successful flare to life in the test validates the basic concept in a controlled environment. Engineers are now looking toward integrating this technology into actual spacecraft designs.

How soon might we see this thruster powering a mission beyond Earth orbit?

Cosmic Deep Dive: How Laser Communications Transmit Data from Space

If the distance from Earth to the Moon were scaled down to one kilometer, a laser communication beam would still need to hit a receiver the size of a small coin while both ends move at orbital speeds. The process begins when a spacecraft's laser terminal modulates data onto a narrow beam of light, which then travels through space at 300,000 kilometers per second to reach a ground-based telescope. This method allows for data rates high enough to support live high-definition video streams, far surpassing the capabilities of radio frequency systems used in earlier missions. During Artemis II, the laser terminal made it possible for millions of people to watch detailed footage of the crew's journey around the Moon. Alignment must be maintained with extreme accuracy, often using advanced tracking systems to account for the spacecraft's motion and any atmospheric effects on the final leg of the journey. Despite these engineering feats, one lingering question is how to ensure reliable performance when the line of sight passes close to the Sun, where interference could disrupt the signal.
