Lunar Shadows: A Cold Embrace for Hyper-Stable Lasers

Researchers want to put super stable lasers in dark Moon craters. This could help spacecraft navigate better and improve timekeeping.

Lasers in dark Moon craters could be stable for minutes, much longer than the few seconds possible on Earth. This could greatly improve navigation.

To achieve longer driving distances, planetary #robotics missions require accurate localization 🧭 to counteract position uncertainty. Typically, #rover global localization has been performed manually by humans, which is accurate but time-consuming ⏳ https://www-robotics.jpl.nasa.gov/media/documents/2024_Global_Localization_ICRA.pdf

Star trackers 🎇 are known for their accuracy, making them indispensable for #DeepSpace missions, where other reference points might not be available. They capture images of the night sky, comparing them to an onboard star map 🌌. The Deep Space Network* (#DSN) extends navigation capabilities by employing large antennas 📡 to track spacecraft https://findyourconstellation.com/how-space-missions-navigate-using-constellations

#EscaPADE will launch on the #BlueOrigin #NewGlenn vehicle in Fall 📆 2025. It will go into a ~1-year ⏳, kidney bean-shaped Earth-proximity phase 💤 before returning to a low-altitude perigee for a Trans-Mars Injection (TMI) engine burn. This burn in November 📆 2026, taking advantage of the Oberth Effect, sends Blue and Gold on their way to #Mars 🔴 https://escapade.ssl.berkeley.edu/mission-design

From Earth to #Mars lasts about 200 days. To safely go from those speeds down to zero in that short amount of time requires “slamming on the brakes”. Successful #aerobraking depends upon precise navigation, knowledge of weather, and a solid understanding of the forces the craft can withstand. https://science.nasa.gov/planetary-science/programs/mars-exploration/mission-timeline

Challenges of #SpaceNavigation : If #Earth were the size of a softball, the #ISS would be orbiting just above the seams, the #Moon would be a #marble about 2 meters away, and #Mars would be 1.2 to 2.4 kilometers away. The targets are small and moving. https://timeandnavigation.si.edu/navigating-space/challenges

Chris Potts compared the target requirements of #landing the #Spirit rover inside a specific #crater on Mars 🔴 to being able to shoot a #basketball 🏀 through a hoop 9000 miles away.
Since there’s no #GPS in outer space, navigators process the radiometric tracking data received from the #DeepSpaceNetwork (#DSN) to determine the #spacecraft’s #position and velocity. They also use optical data, where the spacecraft takes a picture of the star background to help refine the spacecraft’s trajectory https://www.universetoday.com/37934/the-navigators-how-we-fly-spacecraft-around-the-solar-system

When a #spacecraft is launched from #Earth 🌍, its forward #velocity combined with the gravitational pull of Earth cause it to travel in a curved path.
