Without an effectively carried out insertion maneuver, CAPSTONE will fly by the Moon without making it into orbit, as revealed in blue. CAPSTONE exposed in lunar Sunrise: CAPSTONE will fly in cislunar area– the orbital space near and around the Moon. The schedule of CAPSTONEs previous maneuvers was flexible based on the spacecrafts efficiency and other factors, this orbit insertion should take location at precisely the best time to put CAPSTONE in the proper orbit. When in lunar orbit, CAPSTONE is scheduled to fire its thrusters once every six-and-a-half days, if required, to remain on its orbit for at least 6 months, permitting NASA and its partners to comprehend how to operate in this unique orbit. CAPSTONE will do this by interacting straight with NASAs Lunar Reconnaissance Orbiter– which has actually been in orbit around the Moon given that 2009– to determine its own position in space.

Today, November 13, CAPSTONE will reach the Moon and end up being the very first spacecraft to get in into an unique, extended orbit that will support NASAs Artemis missions.
Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) is a microwave oven-sized satellite, weighing simply 55 pounds, that will be the first CubeSat to fly to and run at the Moon. It functions as a pathfinder for Gateway, a Moon-orbiting area station that becomes part of NASAs Artemis program. CAPSTONEs objective will assist lower risk for future spacecraft, including Orion, by confirming innovative navigation technologies and validating the characteristics of a type of halo-shaped orbit that has actually never ever been flown before.
The pull of gravity from Earth and the Moon communicate in this unique orbit– formally called a near rectilinear halo orbit (NRHO)– to enable for a semi-stable orbit. There, physics does most of the work of keeping spacecraft in orbit at the Moon. This reduces the need for spacecraft to utilize fuel to maintain the NRHO compared to other comparable orbits. NASA currently has big prepare for this special type of orbit. Engineers expect it will enable them to park larger spacecraft– including Gateway– in orbit at the Moon for a minimum of 15 years. Fuel efficiency is key for such long-duration objectives.
In this animation, the prepared trajectory for CAPSTONEs near rectilinear halo orbit (NRHO) is shown in red. The NRHO insertion maneuver and two subsequent correction maneuvers make sure that the spacecraft properly inserts into the NRHO.

Over the previous four months, CAPSTONE has actually been navigating an uncommon yet effective deep-space path to the Moon. This path– called a ballistic lunar transfer– follows gravitational shapes in deep space and permits spacecraft to reach their destination using up little energy. Advanced Space, a Colorado small company that runs and owns CAPSTONE on behalf of NASA designed this special trajectory.
CAPSTONE has carried out 5 maneuvers over the past few months to line up its trajectory for orbit insertion, with the group adapting to unforeseen difficulties to keep CAPSTONE on track. A final maneuver on October 27 teed up the spacecrafts arrival to the Moon.
” What this CAPSTONE group has conquered to date has actually been unbelievable, revealing strength while getting valuable knowledge. We are grateful to the extraordinary individuals who have actually exceeded and beyond in NASA, Terran Orbital, Stellar Exploration, NASAs Deep Space Network, and Advanced Space for their determined work on recovery efforts,” stated Bradley Cheetham, primary private investigator for CAPSTONE and chief executive officer of Advanced Space. “Overcoming challenges is the function of a pathfinding objective– CAPSTONE is capitalizing on that goal.”

Its technique will be perfectly aligned for NRHO insertion– the important point of its path when CAPSTONE reaches the end of its gravity-driven track and gets here at the Moon. Though the schedule of CAPSTONEs prior maneuvers was flexible based on the spacecrafts efficiency and other elements, this orbit insertion should take place at precisely the right time to put CAPSTONE in the correct orbit. While taking a trip 3,800 miles per hour, it will perform its delicate, precisely timed propulsive maneuver to enter orbit, like a flying trapeze artist who leaps from one arc to another with a decisive, acrobatic movement.
The initial orbit insertion maneuver is prepared for Sunday, November 13, at 7:18 p.m. EST (4:18 p.m. PST). The CAPSTONE group expects it will take at least 5 days to evaluate data, perform 2 clean-up maneuvers, and validate successful insertion into the near rectilinear halo orbit.
Beyond that, other goals still lay ahead for this pathfinder CubeSat. As soon as in lunar orbit, CAPSTONE is set up to fire its thrusters once every six-and-a-half days, if needed, to remain on its orbit for at least six months, allowing NASA and its partners to comprehend how to run in this special orbit. Specifically, CAPSTONE will validate the propulsion requirements for preserving its orbit as predicted by models, decreasing logistical unpredictabilities for future spacecraft.
Additionally, an essential software innovation– the Cislunar Autonomous Positioning System (CAPS)– will be checked in the coming months. CAPS will show ingenious spacecraft-to-spacecraft navigation options that will permit future spacecraft to identify their area without having to rely specifically on tracking from Earth. CAPSTONE will do this by communicating straight with NASAs Lunar Reconnaissance Orbiter– which has remained in orbit around the Moon since 2009– to identify its own position in area. This capability could allow future spacecraft to carry out on their own with less assistance from the ground and permit ground-based antennas to prioritize valuable science data over more regular operational tracking.
CAPSTONEs mission will demonstrate several innovations that will lay a structure for business support of future lunar operations. NASA partners are evaluating cutting-edge tools for mission planning and operations, leading the way and broadening opportunities for small and more cost effective space and expedition objectives to the Moon, Mars, and other locations throughout the planetary system.
CAPSTONE is commercially owned and operated by Advanced Space in Westminster, Colorado. It represents an ingenious partnership between NASA and industry to offer rapid results and feedback to inform future exploration and science objectives. The spacecraft was designed and built by Terran Orbital. Operations are carried out collectively by groups at Advanced Space and Terran Orbital.
NASAs Small Spacecraft Technology program within the agencys Space Technology Mission Directorate (STMD) funds the demonstration objective. The program is based at NASAs Ames Research Center in Californias Silicon Valley. The advancement of CAPSTONEs navigation innovation is supported by NASAs Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) program, likewise within STMD. The Artemis Campaign Development Division within NASAs Exploration Systems Development Mission Directorate moneyed the launch and supports mission operations.
