2023年9月27日 · With laser communications, NASA can significantly accelerate the data transfer process and empower more discoveries. Optical, or laser, communications will enable 10 to 100 times more data transmitted back to Earth than current radio frequency systems.

2024年10月9日 · 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.

2022年8月11日 · NASA uses lasers to send information to and from Earth, employing invisible beams to traverse the skies, sending terabytes of data – pictures and videos – to increase our knowledge of the universe. This capability is known as laser, or optical, communications, even though these eye-safe, infrared beams can’t be seen by human eyes.

2021年5月12日 · With laser communications, NASA can significantly accelerate the data transfer process and empower more discoveries. Laser communications will enable 10 to 100 times more data transmitted back to Earth than current radio frequency systems.

2024年10月3日 · NASA’s Deep Space Optical Communications technology demonstration broke yet another record for laser communications this summer by sending a laser signal from Earth to NASA’s Psyche spacecraft about 290 million miles (460 million kilometers) away. That’s the same distance between our planet and Mars when the two planets are farthest apart.

2023年11月24日 · An experiment aboard NASA’s Psyche mission achieved “first light” by sending and receiving its first deep-space laser communications from far beyond the moon.

ATLAS features new technologies that allow it to collect a more detailed, precise picture of the heights of the planet’s ice, vegetation, land surface, water and clouds. As it orbits over the poles, ATLAS has three major tasks: Send pulses of laser light to the ground, collect the returning photons in a telescope, and record the photon travel time.

2024年10月17日 · With data rates 10-100x higher than radio frequencies, laser communications could support robotic spacecraft throughout our solar system and even future astronauts exploring Mars. Join us live for a discussion on these milestones and what’s ahead for the second year of the experiment’s two-year test.

2020年12月15日 · NASA is exploring the use of lasers to communicate over potentially interplanetary distances. Through collaboration with the private sector, future NASA missions could use a powerful beam to send data back to Earth. Credit: NASA/JPL

2025年3月14日 · NASA’s Earth-observing laser in orbit passed a milestone on March 9 at 12:51 p.m. EDT — 16:51:00.268 UTC, to be precise — as its laser instrument fired for the 2 trillionth time and measured clouds off the coast of East Antarctica. ICESat-2’s height-measuring laser instrument, ATLAS, fired its 2 trillionth shot on March 9, detecting ...
