Abstract Objective. To standardize outcome measures in systemic lupus erythematosus (SLE). Three indices were identified which could adequately describe (disease activity, damage from disease, and health status); we here the development of Disease Activity Index. Methods. Twenty‐four variables as important factors a disease activity index. These used to generate 574 patient profiles, rated on scale 0–10 by 14 rheumatologists. A second rating 10 profiles yielded scores that not significantly...
FARSIDE (Farside Array for Radio Science Investigations of the Dark ages and Exoplanets) is a mission concept to place low radio frequency interferometric array on farside Moon.This was studied as part Decadal Survey Astronomy Astrophysics 2020 (Astro2020), in Astro2020-equivalent Planetary Mission Concept Studies program.The NASA-funded design study focused instrument, deployment rover, lander base station.The result an architecture broadly consistent with requirements Probe-class division...
This is the final report submitted to NASA for a Probe-class concept study of "Farside Array Radio Science Investigations Dark ages and Exoplanets" (FARSIDE), low radio frequency interferometric array on farside Moon. The design focused instrument, deployment rover, lander base station, delivered an architecture broadly consistent with requirements Probe mission. notional consists 128 dipole antennas deployed across 10 km area by tethered station central processing, power data transmission...
This paper presents a technology development initiative focused on delivering SmallSats to orbit variety of bodies using aerocapture. Aerocapture uses the drag single pass through atmosphere capture into instead relying large quantities rocket fuel. Using modulation flight control, an aerocapture vehicle adjusts its area during atmospheric single-stage jettison skirt, allowing it target particular science in presence uncertainties. A team from JPL, NASA Ames, and CU Boulder has worked...
This paper presents the feasibility study of REMORA CubeSat mission concept with an integrated miniature robotic payload to prevent large debris collisions. While orbital poses a threat spacecraft, collision between largest space objects is significant concern. The DARPA Catcher's Mitt compiled list highest priority objects. By annually removing 5-10 these high objects, it may be possible stabilize medium sized population. Instead deorbiting would use COTS components and secondary launches...
The Investigation of Convective Updrafts, or INCUS, mission is a NASA Earth Ventures Mission (EV-M) that will measure, for the first time ever, convective mass flux (CMF) storm systems. INCUS led by Colorado State University (CSU)-based principal investigator with project management and system engineering delegated to Jet Propulsion Laboratory (JPL) in Pasadena, CA. uses Ka-band radars on three spacecraft are separated measure change vertical columns water ice storms Machine learning...
The Innovation Foundry at NASA's Jet Propulsion Laboratory (JPL) is developing a new tool suite for rapid concurrent and collaborative spacecraft mission architecture design with Team Xc. Xc JPL's agile team Earth orbiting interplanetary CubeSat SmallSat missions of "ESPA-class" (approximately 180 kg mass) below. Previously successful designs that have come from include the MarCO traveled Insight lander to Mars in 2018, as well RainCube continues operate successfully orbit. Since began 2013,...
The standardization of launch opportunities as secondary payloads, coupled with the miniaturization digital electronics due to Moore's law, has enabled a new class space missions at greatly reduced costs - SmallSat missions. Unfortunately, desires concept developers are often in conflict limited technical budgets afforded within constraints mission. Chief amongst these budgets, ironically, mass and volume that enable them first place. Mass consumed closure other systems: science error...
This paper presents the concept to provide a robust and scalable robotic solution enable SmallSat clusters via Cluster Forming On-board Robotic Manipulators (C-FORM). Instead of dedicated launches large science instruments, small satellites could be piggybacked as secondary payloads. After deployment, SmallSats will rendezvous. Miniature robot arms deploy perform docking second SmallSat, similar on ISS or space shuttle. method accommodates uncertainty in GNC while reducing risk spacecraft...
Within the Mars science community, there is growing interest in role that small spacecraft missions can play increasing breadth and frequency of exploration. Fueled by significant advances miniaturization instruments avionics, innovative concepts for delivery to Mars, emerging low-cost capabilities fast-growing NewSpace marketplace, appear capable achieving compelling results at unprecedentedly low mission cost, far below current NASA Discovery Program cost cap. We report on development a...
The purpose of the NASA Pre-Phase A project life cycle phase is, "To produce a broad spectrum ideas and alternatives for missions from which new programs/projects can be selected, to determine feasibility [the] desired system, develop mission concepts, draft system-level requirements, assess performance, cost, schedule feasibility; identify potential technology needs, scope." There are, however, limited resources (time, money, workforce) with conduct this trade space exploration. question...
