NASA and Northrop Grumman are preparing to send the company’s next cargo mission to the International Space Station, flying research to support Artemis missions to the Moon and human exploration of Mars and beyond, while improving life on Earth. SpaceX’s Falcon 9 rocket will launch Northrop Grumman’s 23rd commercial resupply services mission to the orbiting … Read more
In the vacuum of space, where temperatures can plunge to minus 455 degrees Fahrenheit, it might seem like keeping things cold would be easy. But the reality is more complex for preserving ultra-cold fluid propellants – or fuel – that can easily overheat from onboard systems, solar radiation, and spacecraft exhaust. The solution is a … Read more
A team at JPL packed up three small Moon rovers, delivering them in February to the facility where they’ll be attached to a commercial lunar lander in preparation for launch. The rovers are part of a project called CADRE that could pave the way for potential future multirobot missions. NASA/JPL-Caltech A trio of suitcase-size rovers … Read more
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
