A host of CubeSats, or small satellites, are undergoing the final stages of processing at Rocket Lab USA’s facility in Huntington Beach, California, for NASA’s first mission dedicated solely to spacecraft of their size. This will be the first launch under the agency’s new Venture Class Launch Services. Scientists, including those from NASA and various universities, began arriving at the facility in early April with spacecraft small enough to be a carry-on to be prepared for launch. A team from NASA’s Goddard Spaceflight Center in Greenbelt, Maryland, completed final checkouts of a CubeSat called the Compact Radiation Belt Explorer (CeREs), before placing the satellite into a dispenser to hold the spacecraft during launch inside the payload fairing. Among its missions, the satellite will examine the radiation belt and how electrons are energized and lost, particularly during events called microbursts — when sudden swarms of electrons stream into the atmosphere. This facility is the final stop for designers and builders of the CubeSats, but the journey will continue for the spacecraft. Rocket Lab will soon ship the satellites to New Zealand for launch aboard the company’s Electron orbital rocket on the Mahia Peninsula this summer. The CubeSats will be flown on an Educational Launch of Nanosatellites (ELaNa) mission to space through NASA’s CubeSat Launch Initiative. CeREs is one of the 10 ELaNa CubeSats scheduled to be a part of this mission.

Contamination from organic molecules can harm delicate instruments and engineers are taking special care at NASA to prevent that from affecting the James Webb Space Telescope (and all satellites and instruments). Recently, Nithin Abraham, a Thermal Coatings Engineer placed Molecular Adsorber Coating or "MAC" panels in the giant chamber where the Webb telescope will be tested. This contamination can occur through a process when a vapor or odor is emitted by a substance. This is called "outgassing." The "new car smell" is an example of that, and is unhealthy for people and sensitive satellite instruments. So, NASA engineers have created a new way to protect those instruments from the damaging effects of contamination coming from outgassing. "The Molecular Adsorber Coating (MAC) is a NASA Goddard coatings technology that was developed to adsorb or entrap outgassed molecular contaminants for spaceflight applications," said Nithin Abraham, Thermal Coatings Engineer at NASA's Goddard Space Flight Center in Greenbelt, Maryland. MAC is currently serving as an innovative contamination mitigation tool for Chamber A operations at NASA Johnson Space Center in Houston, Texas. MAC can be used to keep outgassing from coming in from outside areas or to capture outgassing directly from hardware, components, and within instrument cavities. In this case, MAC is helping by capturing outgassed contaminants outside the test chamber from affecting the Webb components. MAC is expected to capture the outgassed contaminants that exist in the space of the vacuum chamber (not from the Webb components).

Inside NASA's giant thermal vacuum chamber, called Chamber A, at NASA's Johnson Space Center in Houston, the James Webb Space Telescope's Pathfinder backplane test model, is being prepared for its cryogenic test. Previously used for manned spaceflight missions, this historic chamber is now filled with engineers and technicians preparing for a crucial test. Exelis developed and installed the optical test equipment in the chamber. "The optical test equipment was developed and installed in the chamber by Exelis," said Thomas Scorse, Exelis JWST Program Manager. "The Pathfinder telescope gives us our first opportunity for an end-to-end checkout of our equipment." "This will be the first time on the program that we will be aligning two primary mirror segments together," said Lee Feinberg, NASA Optical Telescope Element Manager. "In the past, we have always tested one mirror at a time but this time we will use a single test system and align both mirrors to it as though they are a single monolithic mirror." The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, the European Space Agency and the Canadian Space Agency.

Engineers and technicians manually deployed the secondary mirror support structure (SMSS) of the James Webb Space Telescope's Pathfinder backplane test model, outside of a giant space simulation chamber called Chamber A, at NASA's Johnson Space Center in Houston. This historic test chamber was previously used in manned spaceflight missions and is being readied for a cryogenic test of a Webb telescope component. In the weightless environment of space, the SMSS is deployed by electric motors. On the ground, specially trained operators use a hand crank and a collection of mechanical ground support equipment to overcome the force of gravity. "This structure needs to be in the deployed configuration during the cryogenic test to see how the structure will operate in the frigid temperatures of space," said Will Rowland, senior mechanical test engineer for Northrop Grumman Aerospace Systems, Redondo Beach, California. "The test also demonstrates that the system works and can be successfully deployed." After the deployment was completed, Chamber A's circular door was opened and the rails (seen in the background of the photo) were installed so that the Pathfinder unit could be lifted, installed and rolled into the chamber on a cart. The team completed a fit check for the Pathfinder. Afterwards they readied the chamber for the cryogenic test, which will simulate the frigid temperatures the Webb telescope will encounter in space. “The team has been doing a great job keeping everything on schedule to getting our first optical test results, " said Lee Feinberg, NASA Optical Telescope Element Manager. The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built.

Inside the Integrated Processing Facility at Vandenberg Space Force Base in California, NASA’s Landsat 9 observatory is lowered onto a fixture structure on July 12, 2021. Landsat 9 will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex 3 at Vandenberg in September 2021. The launch is being managed by NASA’s Launch Services Program based at Kennedy Space Center, America’s multiuser spaceport. The Landsat 9 satellite will continue the nearly 50-year legacy of previous Landsat missions. It will monitor key natural and economic resources from orbit. Landsat 9 is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The satellite will carry two instruments: the Operational Land Imager 2, which collects images of Earth’s landscapes in visible, near infrared and shortwave infrared light, and the Thermal Infrared Sensor 2, which measures the temperature of land surfaces. Like its predecessors, Landsat 9 is a joint mission between NASA and the U.S. Geological Survey.
