      Northrop Grumman’s Cygnus spacecraft and the International Space Station above western Mongolia (Credits: NASA). Northrop Grumman’s uncrewed Cygnus spacecraft is scheduled to depart the International Space Station on Friday, July 12, five and a half months after delivering more than 8,200 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo to the orbiting laboratory for NASA and its international partners.
      This mission was the company’s 20th commercial resupply mission to the space station for NASA.
      Live coverage of the spacecraft’s departure will begin at 6:30 a.m. EDT on the NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.
      Flight controllers on the ground will send commands for the space station’s Canadarm2 robotic arm to detach Cygnus from the Unity module’s Earth-facing port, then maneuver the spacecraft into position for its release at 7 a.m. NASA astronaut Mike Barratt will monitor Cygnus’ systems upon its departure from the space station.
      Following unberthing, theKentucky Re-entry Probe Experiment-2 (KREPE-2), stowed inside Cygnus, will take measurements to demonstrate a thermal protection system for the spacecraft and its contents during re-entry in Earth’s atmosphere.
      Cygnus – filled with trash packed by the station crew – will be commanded to deorbit on Saturday, July 13, setting up a destructive re-entry in which the spacecraft will safely burn up in Earth’s atmosphere.
      The Northrop Grumman spacecraft arrived at the space station Feb. 1, following a launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

      Moving across a background of stars, the six red dots in this composite picture indicate the location of six sequential detections of the first near-Earth object discovered by NEOWISE after the spacecraft came out of hibernation in 2013: the asteroid 2013 YP139. The inset shows a zoomed-in view of one of the detections.NASA/JPL-Caltech Observed by NASA’s WISE mission, this image shows the entire sky seen in infrared light. Running through the center of the image and seen predominantly in cyan are the stars of the Milky Way. Green and red represent interstellar dust.NASA/JPL-Caltech/UCLA NASA’s near-Earth-object-hunting mission NEOWISE is nearing its conclusion. But its work will carry on with NASA’s next-generation infrared mission: NEO Surveyor.
      After more than 14 successful years in space, NASA’s NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) mission will end on July 31. But while the mission draws to a close, another is taking shape, harnessing experience gained from NEOWISE: NASA’s NEO Surveyor (Near Earth Object Surveyor), the first purpose-built infrared space telescope dedicated to hunting hazardous near-Earth objects. Set for launch in late 2027, it’s a major step forward in the agency’s planetary defense strategy.
      “After developing new techniques to find and characterize near-Earth objects hidden in vast quantities of its infrared survey data, NEOWISE has become key in helping us develop and operate NASA’s next-generation infrared space telescope. It is a precursor mission,” said Amy Mainzer, principal investigator of NEOWISE and NEO Surveyor at the University of California, Los Angeles. “NEO Surveyor will seek out the most difficult-to-find asteroids and comets that could cause significant damage to Earth if we don’t find them first.”
      Seen here in a clean room at the Space Dynamics Laboratory in Logan, Utah, the WISE mission’s telescope is worked on by engineers. Avionics hardware and solar panels would later be attached before the spacecraft’s launch on Dec. 14, 2009. SDL WISE Beginnings
      NEOWISE’s end of mission is tied to the Sun. About every 11 years, our star experiences a cycle of increased activity that peaks during a period called solar maximum. Explosive events, such as solar flares and coronal mass ejections, become more frequent and heat our planet’s atmosphere, causing it to expand. Atmospheric gases, in turn, increase drag on satellites orbiting Earth, slowing them down. With the Sun currently ramping up to predicted maximum levels of activity, and with no propulsion system for NEOWISE to keep itself in orbit, the spacecraft will soon drop too low to be usable.
      The infrared telescope is going out of commission having exceeded scientific objectives for not one, but two missions, beginning as WISE (Wide-field Infrared Survey Explorer).
      Managed by NASA’s Jet Propulsion Laboratory in Southern California, WISE launched in December 2009 with a six-month missionto scan the entire infrared sky. By July 2010, WISE had achieved this with far greater sensitivity than previous surveys, and NASA extended the mission until 2011.
      During this phase, WISE studied distant galaxies, outgassing comets, exploding white dwarf stars, and brown dwarfs. It identified tens of millions of actively feeding supermassive black holes. It also generated data on circumstellar disks — clouds of gas, dust, and rubble spinning around stars — that citizen scientists continue to mine through the Disk Detective project.
      In addition, it excelled at finding main belt asteroids, as well as near-Earth objects, and discovered the first known Earth Trojan asteroid. What’s more, the mission provided a census of dark, faint near-Earth objects that are difficult for ground-based telescopes to detect, revealing that these objects constitute a sizeable fraction of the near-Earth object population.
      Comet NEOWISE was discovered by its namesake mission on March 27, 2020, and became a dazzling celestial object visible in the Northern Hemisphere for several weeks that year. It was one of 25 comets discovered by the mission.SDL/Allison Bills Infrared Heritage
      Invisible to the naked eye, infrared wavelengths are emitted by warm objects. To keep the heat generated by WISE itself from interfering with its infrared observations, the spacecraft relied on cryogenic coolant. By the time the coolant had run out, WISE had mapped the sky twice, and NASA put the spacecraft into hibernation in February 2011.
      Soon after, Mainzer and her team proposed a new mission for the spacecraft: to search for, track, and characterize near-Earth objects that generate a strong infrared signal from their heating by the Sun.
      “Without coolant, we had to find a way to cool the spacecraft down enough to measure infrared signals from asteroids,” said Joseph Masiero, NEOWISE deputy principal investigator and a scientist at IPAC, a research organization at Caltech in Pasadena, California. “By commanding the telescope to stare into deep space for several months, we determined it would radiate only enough heat to reach lower temperatures that would still allow us to acquire high-quality data.” NASA reactivated the mission in 2013 under the Near-Earth Object Observations Program, a precursor to the agency’s current planetary defense program, with the new name NEOWISE.
      By repeatedly observing the sky from low Earth orbit, NEOWISE has made 1.45 million infrared measurements of over 44,000 solar system objects to date. That includes more than 3,000 NEOs, 215 of which the space telescope discovered. Twenty-five of those are comets, among them the famed comet NEOWISE that was visible in the night sky in the summer of 2020.
      “The spacecraft has surpassed all expectations and provided vast amounts of data that the science community will use for decades to come,” said Joseph Hunt, NEOWISE project manager at JPL. “Scientists and engineers who worked on WISE and through NEOWISE also have built a knowledge base that will help inform future infrared survey missions.”
      The space telescope will continue its survey until July 31. Then, on Aug. 8, mission controllers at JPL will send a command that puts NEOWISE into hibernation for the last time. Since its launch, NEOWISE’s orbit has been dropping closer to Earth. NEOWISE is expected to burn up in our planet’s atmosphere sometime between late 2024 and early 2025.
      More About the Mission
      NEOWISE and NEO Surveyor support the objectives of NASA’s Planetary Defense Coordination Office (PDCO) at NASA Headquarters in Washington. The NASA Authorization Act of 2005 directed NASA to discover and characterize at least 90% of the near-Earth objects more than 140 meters (460 feet) across that come within 30 million miles (48 million kilometers) of our planet’s orbit. Objects of this size can cause significant regional damage, or worse, should they impact the Earth.
      JPL manages and operates the NEOWISE mission for PDCO within the Science Mission Directorate. The Space Dynamics Laboratory in Logan, Utah, built the science instrument. Ball Aerospace & Technologies Corp. of Boulder, Colorado, built the spacecraft. Science data processing, archiving, and distribution is done at IPAC at Caltech. Caltech manages JPL for NASA.
