The information I find is mixed or I...Wed, 15 Apr 2026 22:27:00 GMThttps://space.stackexchange.com/questions/69460/what-is-the-fate-of-krypton-exhaust-from-starlink-thrustersIf the thrusters have a specific impulse of 1500s, that means the krypton atoms are traveling roughly 15 km/s when they exit the nozzle, which exceeds the escape velocity of earth. This may or may not be relevant, depending on how dense the atmosphere / exosphere is where the thruster is fired, and also depending on which way the thruster is pointed. (If the satellite's speed is being ...Sun, 12 Apr 2026 23:49:00 GMThttps://space.stackexchange.com/questions/46102/how-much-krypton-is-stored-on-a-starlink-satelliteHow much krypton (fuel) is there for the krypton-powered ion thrusters on Starlink satellites and how long does it last?Tue, 14 Apr 2026 07:47:00 GMThttps://space.stackexchange.com/questions/36200/what-performance-specification-would-be-lower-for-krypton-than-for-xenon-in-hallThe Ars Technica article SpaceX scrubs first attempt to launch 60 Internet satellites [Updated] (found here) discusses the use of Krypton rather than Xenon in the Starlink Hall effect ion thruster...Sat, 11 Apr 2026 17:16:00 GMThttps://space.stackexchange.com/questions/36165/why-will-starlink-satellites-use-krypton-instead-of-xenon-for-electric-propulsioTo adjust position on orbit, maintain intended altitude, and deorbit, Starlink satellites feature Hall thrusters powered by krypton. (emphasis added) Most of the electric propulsion systems that I've heard of use xenon.Mon, 20 Apr 2026 04:48:00 GMThttps://space.stackexchange.com/questions/66431/what-are-the-tradeoffs-in-propellant-choices-for-ion-electric-based-enginesThink F = ma, where F in this case is the force of the electric field acting on the ion. If you change fuels (say from xenon to krypton, which is lighter), but don't change field strengths, then F stays the same, while m decreases, which means a (acceleration on the ion) must be bigger.Thu, 16 Apr 2026 03:27:00 GMThttps://space.stackexchange.com/questions/48799/how-much-krypton-do-starlink-satellites-carry-when-they-are-first-deployedStarlink satellites use krypton as propellant. This answer roughly estimates 2.3 kg of Krypton based on a total delta-V of 190 m/s and an exhaust velocity of 20,000 m/s. But how close is that to re...Fri, 17 Apr 2026 02:36:00 GMThttps://space.stackexchange.com/questions/52477/how-much-of-the-worlds-xenon-has-been-used-in-spaceflight-altogether-is-it-a-lKrypton is far more common (~1 ppm, over 10x that of xenon), and is produced with similar strategies, so it is a lot cheaper than xenon, at 290 USD per kilogram. SpaceX is launching Starlink very fast, so they can't wait for a suitable xenon supply to show up. Xenon is commonly used only because it has a higher performance.Sun, 29 Mar 2026 12:24:00 GMThttps://space.stackexchange.com/questions/44476/why-might-krypton-have-a-lower-utilization-fraction-than-xenon-for-ion-propulsio4 A comment below Why will Starlink satellites use krypton instead of xenon for electric propulsion? links to the 2011 preprint A Performance Comparison of Xenon and KryptonPropellant on an SPT-100 Hall Thruster; IEPC-2011-003 which explains that in this study using a SPT-100 Hall Thruster krypton had a lower utilization fraction than xenon.Thu, 16 Apr 2026 11:48:00 GMThttps://space.stackexchange.com/questions/39839/what-are-the-advantages-of-solid-iodine-propellant-and-how-is-it-used-for-ion-prPeople like to use the word "solid" to advertise that the propellant is stored in stolid state, instead of a pressurised tank of a gas as xenon or krypton. Yes, you have to sublimate it by heating the iodine container. Cons: You have to spend energy to heat the container and get iodine in gas form.Thu, 09 Apr 2026 10:38:00 GMT
