Illinois and New York Wiped Clean

Solar-Panel Dust Accumulation and Cleanings

Just like drivers sometimes use snow to clean their car mirrors in winter, two Exelis Inc. engineers are practicing "snow cleaning'" on a test telescope mirror for the James Webb Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland. By shooting carbon dioxide snow at the surface, engineers are able to clean large telescope mirrors without scratching them. "The snow-like crystals (carbon dioxide snow) knock contaminate particulates and molecules off the mirror," said Lee Feinberg, NASA optical telescope element manager. This technique will only be used if the James Webb Space Telescope's mirror is contaminated during integration and testing. The Webb telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. With a mirror seven times as large as Hubble's and infrared capability, Webb will be capturing light from 13.5 billion light years away. To do this, its mirror must be kept super clean. "Small dust particles or molecules can impact the science that can be done with the Webb," said Feinberg. "So cleanliness especially on the mirrors is critical." Webb is an international project led by NASA with its partners, the European Space Agency and the Canadian Space Agency. Image credit: NASA/Goddard/Chris Gunn

What looks like a teleporter from science fiction being draped over NASA's James Webb Space Telescope, is actually a &quot;clean tent.&quot; The clean tent protects Webb from dust and dirt when engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland transport the next generation space telescope out of the relatively dust-free cleanroom and into the shirtsleeve environment of the vibration and acoustics testing areas. In two years, a rocket will be the transporter that carries the Webb into space so it can orbit one million miles from Earth and peer back over 13.5 billion years to see the first stars and galaxies forming out of the darkness of the early universe.

Four Extreme Ultraviolet and X-ray Irradiance Sensors or EXIS instruments that will fly aboard four of NOAA's Geostationary Operational Environmental Satellite-R or GOES-R Series spacecraft were recently lined up like babies in a nursery. The EXIS Team at NOAA's Laboratory for Atmospheric and Space Physics (LASP) in Boulder, Colorado took a short timeout during the week of January 20, 2014 to take advantage of a rare photo opportunity. Each EXIS instrument will fly aboard one of the GOES-R series of spacecraft that include GOES-R, S, T, and U. All four EXIS instruments happened to be in the clean room at the same time. It is expected that this will probably be the last time that all four siblings will be in one place together as Flight Model 1 (seen on the left) is being shipped on February 3 to begin integration and testing onto the GOES-R spacecraft at a Lockheed Martin facility in Littleton, Colo. The other instruments have already dispersed to other areas at LASP for continued build and test operations. The EXIS instruments on the GOES-R series satellites are critical to understanding and monitoring solar irradiance in the upper atmosphere, that is, the power and effect of the Sun’s electromagnetic radiation per unit of area. EXIS will be able to detect solar flares that could interrupt communications and reduce navigational accuracy, affecting satellites, high altitude airlines and power grids on Earth. On board the EXIS are two main sensors, the Extreme Ultraviolet Sensor (EUVS) and the X-Ray Sensor (XRS), which will help scientists monitor activity on the sun. The GOES-R series is a collaborative development and acquisition effort between the National Oceanic and Atmospheric Administration and NASA. The GOES-R satellites will provide continuous imagery and atmospheric measurements of Earth’s Western Hemisphere and space weather monitoring.

Teams at NASA’s Michoud Assembly Facility in New Orleans install wash probes into a liquid oxygen tank inside the factory’s cleaning cell on Oct. 25. The tank, which will be used on the core stage of the agency’s SLS (Space Launch System) rocket for its Artemis III mission, will undergo an internal cleaning before moving on to its next phase of production. Inside the cleaning cell, a solution is sprayed into the tank to remove particulates which may collect during the manufacturing process. Once a tank is cleaned, teams use mobile clean rooms for internal access to the tank to prevent external contaminates from entering the hardware. The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage. The core stage, along with its four RS-25 engines, produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis.

A technician prepares a test sample in the Zero Gravity Research Facility clean room at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The Zero Gravity Research Facility contained a drop tower which provided five seconds of microgravity during freefall in its 450-foot deep vacuum chamber. The facility has been used for a variety of studies relating to the behavior of fluids and flames in microgravity. During normal operations, a cylindrical 3-foot diameter and 11-foot long vehicle was used to house the experiments, instrumentation, and high speed cameras. The 4.5-foot long and 1.5-foot wide rectangular vehicle, seen in this photograph, was used less frequently. A 3-foot diameter orb was used for the special ten-second drops in which the package was pneumatically shot to the top of the tower then dropped. The facility also contained a control room, shop offices, tool and equipment rooms, and this clean room. The 242.5-foot long and 19.5-foot wide clean room was equipped with specialized cleaning equipment. In the 1960s the room was rated as a class 10,000 clean room, but I was capable of meeting the class 100 requirements. The room included a fume hood, ultrasonic cleaner, and a laminar flow station which operated as a class 100 environment. The environment in the clean room was maintained at 71° F and a relative humidity of 45- percent.

An engineer in the clean room at Lockheed Martin Space in Littleton, Colorado, affixes a dime-size chip onto the lander deck of NASA's InSight spacecraft. This second microchip, contains 1.6 million names submitted by the public to ride along with InSight to Mars. The chip was installed on Jan. 23, 2018. This joins another microchip that was previously installed that included 800,000 names for a grand total of 2.4 million names going to Mars as early as May 5, 2018. Engineers at NASA's Jet Propulsion Laboratory, Pasadena, California, put the names onto this tiny 0.3 square inches (8 millimeter-square) silicon wafer microchip using an electron beam to write extremely tiny letters with lines smaller than one one-thousandth the width of a human hair. The dime-size chip is affixed to the InSight lander deck and will remain on Mars forever. Normally used to make high-precision nanometer-scale devices, this technique was also used to write millions of names that were transported on NASA Mars rovers and Orion's first test flight. InSight is the first Mars mission dedicated to study the deep interior of Mars.

Engineers and technicians from NASA's Jet Propulsion Laboratory work on the NASA-ISRO Synthetic Aperture Radar (NISAR) science instrument payload in a clean room at JPL on Feb. 3, 2023. The payload is scheduled to ship to India in March 2023. The NISAR mission – a joint effort between NASA and ISRO – will measure changes to Earth's land ice surfaces down to fractions of an inch. Data collected by this satellite will help researchers monitor a wide range of changes critical to life on Earth in unprecedented detail. This includes spotting warning signs of imminent volcanic eruptions, helping to monitor groundwater supplies, tracking the melt rate of ice sheets tied to sea level rise, and observing shifts in the distribution of vegetation around the world. The data will inform humanity's responses to urgent challenges posed by natural disasters and climate change, and help communities prepare for and manage hazards. There are two instruments on the satellite that will send and receive radar signals to and from Earth's surface to make the mission's measurements. An L-band synthetic aperture radar (SAR), which uses a signal wavelength of around 9 inches (24 centimeters), and an S-band SAR with a signal wavelength of nearly 5 inches (12 centimeters). Both will bounce their microwave signal off of the planet's surface and record how long it takes the signal to make one roundtrip, as well as the strength of that return signal. This enables the researchers to calculate the distance from the spacecraft to Earth's surface and thereby determine how the land or ice is changing. An antenna reflector nearly 40 feet (12 meters) in diameter, supported by a deployable boom, will focus the microwave signals sent and received by the SARs. JPL, which is managed for NASA by Caltech in Pasadena, leads the U.S. component of NISAR and is providing the mission's L-band SAR instrument. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. ISRO is providing the spacecraft bus, the S-band SAR, the launch vehicle, and associated launch services and satellite mission operations. https://photojournal.jpl.nasa.gov/catalog/PIA25771

The Sentinel-6A spacecraft sits in its clean room in Germany's IABG space test center. The satellite is being prepared for a scheduled launch in November 2020 from Vandenberg Air Force Base in California. The spacecraft is part of Sentinel-6/Jason-CS, a 10-year mission by U.S and European agencies that will continue to study rising sea levels. The mission consists of two identical satellites, Sentinel-6A and Sentinel-6B, launching five years apart and follows in the footsteps of four other joint U.S.-European satellite missions — TOPEX/Poseidon and Jason-1, Ocean Surface Topography/Jason-2, and Jason-3 — that over the past three decades have documented Earth's oceans rising by an average of 0.1 inches (3 millimeters) per year. Sentinel-6/Jason-CS will study not just sea level change but also changes in ocean circulation, climate variability such as El Niño and La Niña, and weather patterns, including hurricanes and storms. It is being jointly developed by the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellite (EUMETSAT), NASA and the National Oceanic and Atmospheric Administration (NOAA) with funding support from the European Commission and support from France's National Centre for Space Studies (CNES). NASA's contributions to the Sentinel-6 mission are science instrument payloads for the two Sentinel-6 satellites, launch services for those satellites, ground systems supporting the science instruments operations and support for the international Ocean Surface Topography Science Team. https://photojournal.jpl.nasa.gov/catalog/PIA23549

A planetary protection engineer in full-body protective gear carefully collects samples from NASA's Europa Clipper spacecraft to verify its biological cleanliness in a clean room at NASA's Jet Propulsion Laboratory on March 20, 2024. Maintaining and verifying the cleanliness of the spacecraft helps minimize the chance that microbes brought from Earth could compromise future scientific investigations at its destination, Jupiter's moon Europa. This work, referred to as planetary protection, is conducted in keeping with the international 1967 Outer Space Treaty to explore space in a responsible manner that avoids the harmful contamination of celestial bodies. This photo was taken while Europa Clipper was being built in JPL's Spacecraft Assembly Facility. Europa Clipper's three main science objectives are to determine the thickness of the moon's icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission's detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. https://photojournal.jpl.nasa.gov/catalog/PIA26440
