NASA’s LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit. During the first live sky test, NASA’s LCOT produced enough uplink intensity for the TBIRD payload to identify the laser beacon, … Read more
NASA’s TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft — the PTD-3 (Pathfinder Technology Demonstrator-3) — have completed their technology demonstration. The TBIRD payload spent the past two years breaking world records for the fastest satellite downlink from space using laser communications. NASA’s PTD series leverages a common commercial spacecraft to provide a robust … Read more
Using NASA’s first two-way, end-to-end laser relay system, pictures and videos of cherished pets flew through space over laser communications links at a rate of 1.2 gigabits per second — faster than most home internet speeds. NASA astronauts Randy Bresnik, Christina Koch, and Kjell Lindgren, along with other agency employees, submitted photos and videos of … Read more
As part of NASA’s Artemis campaign to return humans to the Moon for the benefit of all, the agency is working with SpaceX to develop the company’s Starship human landing system (HLS), which will land astronauts near the Moon’s South Pole during the Artemis III and Artemis IV missions. On March 14, SpaceX launched the … Read more
By Wayne Smith In his youth, NASA technologist Les Johnson was riveted by the 1974 novel “The Mote in God’s Eye,” by Jerry Pournelle and Larry Niven, in which an alien spacecraft propelled by solar sails visits humanity. Today, Johnson and a NASA team are preparing to test a similar technology. NASA continues to unfurl … Read more
Capable of receiving both radio frequency and optical signals, the DSN’s hybrid antenna has tracked and decoded the downlink laser from DSOC, aboard NASA’s Psyche mission. An experimental antenna has received both radio frequency and near-infrared laser signals from NASA’s Psyche spacecraft as it travels through deep space. This shows it’s possible for the giant … Read more
It’s easy to measure fuel in tanks on Earth, where gravity pulls the liquid to the bottom. But in space, the game changes. Quantifying fuel that’s floating around inside a spacecraft’s tank isn’t so simple. “Because of the very small amount of gravity, fluid doesn’t settle to the bottom of propellant tanks but rather clings … Read more
Establishing sustained operations at the Moon and Mars presents a multitude of opportunities and challenges NASA has yet to encounter. Many of these activities require new technologies and processes to ensure the agency is prepared for its ambitious Artemis missions and those beyond. One of those challenges is working with cryogenic fluids, meaning fluids existing … Read more
A NASA technology experiment on the International Space Station completed its first laser link with an in-orbit laser relay system on Dec. 5, 2023. Together, they complete NASA’s first two-way, end-to-end laser relay system. NASA’s LCRD (Laser Communications Relay Demonstration) and the new space station demonstration, ILLUMA-T (Integrated LCRD Low Earth Orbit User Modem and … Read more
A little more than a year ago, a NASA flight test article came screaming back from space at more than 18,000 mph, reaching temperatures of nearly 2,700 degrees Fahrenheit before gently splashing down in the Pacific Ocean. At that moment, it became the largest blunt body — a type of reentry vehicle that creates a … Read more
