Asteroid Triumph: NASA’s History-Making OSIRIS-REx Mission Awarded Robert Goddard Memorial Trophy
NASA’s OSIRIS-REx team received the prestigious Goddard Memorial Trophy for its historic mission of collecting and returning an asteroid sample, aiding scientific research on the solar system’s origins. NASA’s OSIRIS-REx team was selected as the winner of the National Space Club and Foundation’s 2024 Dr. Robert H. Goddard Memorial Trophy for their tremendous work on the first U.S. mission to bring an asteroid sample to Earth. The winning team received the award at the 67th Annual Robert H.
Rogue Drogue: NASA Decodes OSIRIS-REx’s Parachute Problem Original
NASA’s OSIRIS-REx successfully returned samples from Bennu, despite a minor parachute deployment issue caused by wiring label discrepancies. The main parachute compensated, ensuring a safe landing, with further investigations planned to confirm the cause. NASA’s OSIRIS-REx sample return capsule landed under parachute in the Utah desert on September 24, 2023, and safely delivered a cannister of rocks and dust collected from near-Earth asteroid Bennu.
NASA finds likely cause of OSIRIS-REx parachute deployment sequence Original
NASA's OSIRIS-REx sample return capsule landed under parachute in the Utah desert on Sept. 24, 2023, and safely delivered a cannister of rocks and dust collected from near-Earth asteroid Bennu. Although the delivery was successful, the landing sequence did not go entirely according to plan, with a small parachute called a drogue not deploying as expected.
First NASA asteroid sample return mission on track for fall '23 delivery
NASA's first asteroid sample return spacecraft, OSIRIS-REx, fired its thrusters for 30 seconds on Sept. 21 and nudged its trajectory toward Earth. The resulting course correction keeps the vehicle on track to deliver a sample of asteroid Bennu to Earth on Sept. 24, 2023, completing a seven-year mission.
NASA’s Mars Sample Return Mission Shields Up for Tests
A potential hazard for any space mission, including NASA’s Mars Sample Return, is micrometeorites. These tiny rocks can travel up to 50 miles per second (180,000 mph). At these extreme speeds, “even dust could cause damage to a spacecraft,” said Bruno Sarli, NASA engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Sarli leads a team designing shields to protect NASA’s Mars Earth Entry System from micrometeorites and space debris.
Some asteroids 'aged early' by sun, NASA finds
Scientists from NASA's OSIRIS-REx mission recently learned that surface regeneration happens a lot quicker on asteroids than on Earth. By analyzing rock fractures on asteroid Bennu from high-resolution images taken by the OSIRIS-REx spacecraft, the team discovered that the Sun's heat fractures rocks on Bennu in just 10,000 to 100,000 years.

NASA Finds Some Asteroids Aged Early by Sun - “We Were Surprised”
Recently, scientists from NASA’s OSIRIS-REx mission discovered that surface regeneration occurs on asteroids far more quickly than on Earth. By analyzing high-resolution images of rock fractures on asteroid Bennu taken by the OSIRIS-REx spacecraft, the researchers discovered that the Sun’s heat fractures rocks on Bennu in only 10,000 to 100,000 years.

NASA’s Asteroid Mission Receives Space Foundation’s Exploration Award
NASA's OSIRIS-REx asteroid sample return mission team received the 2022 John L. "Jack" Swigert, Jr., Award for Space Exploration by the Space Foundation, a nonprofit organization that advocates for space exploration and space-inspired industries.
NASA’s Robotic OSAM-1 Mission Completes its Critical Design Review
NASA's On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1), a mission that will be the first to robotically refuel a satellite not designed to be serviced, and will also demonstrate assembly and manufacturing technologies and capabilities, has passed its mission critical design review (CDR)

Video: NASA's OSIRIS-REx celebrates perfect departure maneuver from asteroid Bennu
On Tuesday, Oct. 20, 2020, NASA’s OSIRIS-REx sample collection mission performed a successful “Touch-And-Go” (TAG) maneuver. Credit: NASA's Goddard Space Flight Center NASA's OSIRIS-REx spacecraft is 328,000 miles, or 528,000 kilometers, away from the asteroid Bennu, having fired its engines on May 10 to initiate a return trip to Earth. The spacecraft is on track to deliver an asteroid sample to Earth on September 24, 2023.
Space News: NASA's OSIRIS-REx leaves its mark on Asteroid Bennu
Like boot prints on the Moon, NASA's OSIRIS-REx spacecraft left its mark on asteroid Bennu. Now, new images — taken during the spacecraft's final fly-over on April 7 — reveal the aftermath of its historic encounter with the asteroid. The spacecraft flew within 2.3 miles of the asteroid — the closest it has been since the Touch-and-Go, or TAG, sample collection event on Oct. 20, 2020.
NASA's OSIRIS-REx completes final tour of asteroid Bennu
Credit: NASA's Goddard Space Flight Center NASA's OSIRIS-REx completed its last flyover of Bennu around 6 a.m. EDT (4 a.m. MDT) April 7 and is now slowly drifting away from the asteroid; however, the mission team will have to wait a few more days to find out how the spacecraft changed the surface of Bennu when it grabbed a sample of the asteroid. The OSIRIS-REx team added this flyby to document surface changes resulting from the Touch and Go (TAG) sample collection maneuver Oct. 20, 2020.
How satellites monitor the U.S. food and crop supply
It was a rough year for farmers in Wisconsin and other midwestern states no doubt. Some of that was due to years of low prices and some was due to harsh weather conditions in winter through the growing season. Ag agencies, the government, traders, and individual farmers look for any way they can to get a better feel for how the crops are progressing throughout the season. Something they are relying on more and more are satellites.
Satellites track status of nation's food supply
Three moments in a tumultuous year for farming north of St. Louis, MO, as seen in NASA-USGS Landsat 8 data. On the left is May 7, 2019, as heavy rains delayed planting for many farms. Sept 12, 2019, in the middle, shows bright green signifying growing vegetation, although with a fair amount of brown, bare fields. On the right, Oct. 14, 2019, the light brown indicates harvested fields while darker brown are fields that have not been seeded or fallow all summer.

Tiny satellite's first global map of ice clouds
An experimental small satellite has filled this void and captured the first global picture of the small frozen particles inside clouds, normally called ice clouds. Deployed from the space station in May 2017, IceCube is testing instruments for their ability to make space-based measurements of the small, frozen crystals that make up ice clouds. "Heavy downpours originate from ice clouds," said Dong Wu, IceCube principal investigator at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Help NASA track and predict mosquito-borne disease outbreaks
One of the tools researchers are using to track these mosquitos is citizen science data combining with NASA Earth satellite observations to create new forecast models that can predict the spread of mosquito-carrying diseases, but more data are needed to improve models that can predict and track mosquito-borne diseases. "We do not have enough information on the geographic distribution of mosquito and time-variation in their populations.
NASA's TSIS-1 keeps an eye on sun's power over ozone

Iowa Flood Center joins with NASA to study soil moisture
Farmers are understandably fascinated by soil moisture—after all, nothing grows without water. This summer, students and researchers at the Iowa Flood Center based at the University of Iowa are partnering with NASA on a research project that could help the scientific community better understand and monitor soil moisture.
Arctic sea ice minimum extent reached, El Niño link unclear
According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at Boulder showed the annual minimum extent was 1.70 million square miles (4.41 million square kilometers) on Sept. 11. This year’s minimum is 699,000 square miles (1.81 million square kilometers) lower than the 1981-2010 average.
