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

I am pleased to share that our paper, titled “Orbit Determination Using Difference-of-Arrival Measurements,” has been published in the CEAS Space Journal.
I would like to extend my sincere appreciation to my co-authors and collaborators for their valuable contributions and support throughout this work.
The paper is available at: https://doi.org/10.1007/s12567-025-00674-z

#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
Breaking: NASA's New Horizons discovers "revolutionary" navigation technique called... looking at stars! 🌟
Sure, it's only accurate to within 60 million km (vs ground control's few meters), but it works autonomously light-years from home. Ancient mariners would be proud! ⭐
Three space probes are leaving our solar system — yet are still functioning. After the two Voyager space probes, New Horizons "was launched in 2006, initially to study Pluto," remembers New Scientist. But "it has since travelled way beyond this point, ploughing on through the Kuiper belt, a...
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
#Athena came to rest inside a crater, 250m from its intended target. “With the direction of the sun, the orientation of the #solar panels, and extreme cold temperatures in the crater, #IntuitiveMachines does not expect Athena to recharge 🔋”.
