Artificial Intelligence Plus Your Cell Phone Means Better Maps of Earth!
GLOBE Observer data from various locations showing four directional views: west, north, south, and east. Credit: Huang et al. 2023, International Journal of Applied Earth Observation and Geoinformation, Volume 122, 103382 In 2019, the GLOBE Land Cover project began asking volunteers to help map planet Earth by taking photos of their surroundings facing multiple directions, including north, south, east and west. Now, a new paper by Huang et al. demonstrates how to combine these images using Artificial Intelligence (AI). The paper compares this “multi-view” approach with the old single-view approach–and finds that the multi-view capabilities of the GLOBE Observer app, processed with AI, enable much more accurate mapping.
“We are thrilled about our recent discovery! We’ve observed that the current AI model is increasingly exhibiting human-like behavior, adept at integrating multiple perspectives, synthesizing them, and striving to derive meaning from these views.”

“We are thrilled about our recent discovery!” said Xiao Huang, the paper’s lead author. “We’ve observed that the current AI model is increasingly exhibiting human-like behavior, adept at integrating multiple perspectives, synthesizing them, and striving to derive meaning from these views.”
The most detailed satellite-based maps of our whole planet still can’t show details smaller than hundreds of meters [about 330 feet]. That means that a park in a city may be too small to show up on the global map. When you use the GLOBE Observer: Land Cover app, you help scientists fill in local gaps and contribute to consistent, detailed global maps that should us how our world is changing.

NASA’s Hubble Space Telescope Pauses Science Due to Gyro Issue
Hubble orbiting more than 300 miles above Earth as seen from the space shuttle. NASA NASA is working to resume science operations of the agency’s Hubble Space Telescope after it entered safe mode Nov. 23 due to an ongoing gyroscope (gyro) issue. Hubble’s instruments are stable, and the telescope is in good health.
The telescope automatically entered safe mode when one of its three gyroscopes gave faulty readings. The gyros measure the telescope’s turn rates and are part of the system that determines which direction the telescope is pointed. While in safe mode, science operations are suspended, and the telescope waits for new directions from the ground.
Hubble first went into safe mode Nov. 19. Although the operations team successfully recovered the spacecraft to resume observations the following day, the unstable gyro caused the observatory to suspend science operations once again Nov. 21. Following a successful recovery, Hubble entered safe mode again Nov. 23.
The team is now running tests to characterize the issue and develop solutions. If necessary, the spacecraft can be re-configured to operate with only one gyro. The spacecraft had six new gyros installed during the fifth and final space shuttle servicing mission in 2009. To date, three of those gyros remain operational, including the gyro currently experiencing fluctuations. Hubble uses three gyros to maximize efficiency, but could continue to make science observations with only one gyro if required.
NASA anticipates Hubble will continue making groundbreaking discoveries, working with other observatories, such as the agency’s James Webb Space Telescope, throughout this decade and possibly into the next.
Launched in 1990, Hubble has been observing the universe for more than 33 years. Read more about some of Hubble’s greatest scientific discoveries.

On Nov. 28, 1983, space shuttle Columbia took to the skies for its sixth trip into space on the first dedicated science mission using the Spacelab module provided by the European Space Agency (ESA). The longest shuttle mission at the time also included many other firsts. Aboard Columbia to conduct dozens of science experiments, the first six-person crew of Commander John W. Young, making his record-breaking sixth spaceflight, Pilot Brewster H. Shaw, Mission Specialists Owen K. Garriott and Robert A.R. Parker, and the first two payload specialists, American Byron K. Lichtenberg and German Ulf Merbold representing ESA, the first non-American to fly on a U.S. space mission. During the 10-day Spacelab 1 flight, the international team of astronauts conducted 72 experiments in a wide variety of science disciplines.

Lichtenberg, standing left, and Ulf Merbold of West Germany representing the European Space Agency. Right: The payload patch for Spacelab 1.
In August 1973, NASA and the European Space Research Organization, the forerunner of today’s ESA, agreed on a cooperative plan to build a reusable laboratory called Spacelab to fly in the space shuttle’s cargo bay. In exchange for ESA building the pressurized modules and unpressurized pallets, NASA provided flight opportunities for European astronauts. In December 1977, ESA named physicist Merbold of the Max Planck Institute in West Germany, physicist Wubbo Ockels of The Netherlands, and astrophysicist Claude Nicollier of Switzerland as payload specialist candidates for the first Spacelab mission. In September 1982, ESA selected Merbold as the prime crew member to fly the mission and Ockels as his backup. Nicollier had in the meantime joined NASA’s astronaut class of 1980 as a mission specialist candidate. In 1978, NASA selected biomedical engineer Lichtenberg of the Massachusetts Institute of Technology as its payload specialist with physicist Michael L. Lampton of CalTech as his backup. In April 1982, NASA assigned the orbiter crew of Young, Shaw, Garriott, and Parker. As commander of STS-9, Young made a record-breaking sixth flight into space. The mission’s pilot Shaw, an astronaut from the 1978 class, made his first trip into space. The two mission specialists had a long history with NASA – Garriott, selected as an astronaut in 1965, completed a 59-day stay aboard the Skylab space station in 1973, and Parker, selected in 1967, made his first spaceflight after a 16-year wait. Although the crew included only two veterans, it had the most previous spaceflight experience of any crew up to that time – 84 days between Young’s and Garriott’s earlier missions.

The pressurized module for the first Spacelab mission arrived at KSC on Dec. 11, 1981, from its manufacturing facility in Bremen, West Germany. Additional components arrived throughout 1982 as workers in KSC’s Operations and Checkout Building integrated the payload racks into the module. The ninth space shuttle mission saw the return of the orbiter Columbia to space, having flown the first five flights of the program. Since it arrived back at KSC after STS-5 on Nov. 22, 1982, engineers in the Orbiter Processing Facility (OPF) modified Columbia to prepare it for the first Spacelab mission. The completed payload, including the pressurized module, the external pallet, and the transfer tunnel, rolled over to the OPF, where workers installed it into Columbia’s payload bay on Aug. 16, 1983.

Rollover of Columbia to the Vehicle Assembly Building (VAB) took place on Sept. 24, where workers mated it with an external tank (ET) and two solid rocket boosters (SRBs). Following integrated testing, the stack rolled out to Launch Pad 39A four days later for a planned Oct. 29 liftoff. However, on Oct. 14, managers called off that initial launch attempt after discovering that the engine nozzle of the left hand SRB contained the same material that nearly caused a burn through during STS-8. The replacement of the nozzle required a rollback to the VAB. Taking place on Oct. 17, it marked the first rollback of a flight vehicle in the shuttle’s history. Workers in the VAB demated the vehicle and destacked the left hand SRB to replace its nozzle. Columbia temporarily returned to the OPF on Oct. 19, where workers replaced its fuel cells using three borrowed from space shuttle Discovery and also replaced its waste collection system. Columbia returned to the VAB on Nov. 3 for remating with its ET and SRBs and rolled back out to the launch pad on Nov. 8.

On Nov. 28, 1983, Columbia thundered off KSC’s Launch Pad 39A to begin the STS-9 mission. The shuttle entered an orbit inclined 57 degrees to the equator, the highest inclination U.S. spaceflight at the time, allowing the astronauts to observe about 80 percent of the Earth’s landmasses. Mounted inside Columbia’s payload bay, the first Spacelab 18-foot long module provided a shirt-sleeve environment for the astronauts to conduct scientific experiments in a variety of disciplines. During the Spacelab 1 mission, the STS-9 crew carried out 72 experiments in atmospheric and plasma physics, astronomy, solar physics, materials sciences, technology, astrobiology, and Earth observations. For the first time in spaceflight history, the crew divided into two teams working opposite 12-hour shifts, allowing science to be conducted 24 hours a day. The Tracking and Data Relay Satellite, launched the previous April during the STS-6 mission, and now fully operational, enabled transmission of television and significant amounts of science data to the Payload Operations Control Center, located in the Mission Control Center at NASA’s Johnson Space Center in Houston.

Upon reaching orbit, the crew opened the payload bay doors and deployed the shuttle’s radiators. Shortly after, following a few tense minutes during which the astronauts struggled with a balky hatch, they opened it, translated down the transfer tunnel, and entered Spacelab for the first time. Garriott, Lichtenberg, and Merbold activated the module and turned on the first experiments. For the next nine days, the Red Team of Young, Parker, and Merbold, and the Blue Team of Shaw, Garriott, and Lichtenberg performed flawlessly to carry out the experiments. Young and Shaw managed the shuttle’s systems while the mission and payload specialists conducted the bulk of the research. With ample consumables available, Mission Control granted them an extra day in space to complete additional science. One afternoon, the astronauts chatted with U.S. President Ronald W. Reagan in the White House and German Chancellor Helmut Kohl, attending the European Community Summit in Athens, Greece. The two leaders praised the astronauts for their scientific work and the cooperation between the two countries that enabled the flight to take place.

On Dec. 8, their last day in space, the crew finished the experiments, closed up the Spacelab module, and strapped themselves into their seats to prepare for their return to Earth. Five hours before the scheduled landing, during thruster firings one of Columbia’s five General Purpose Computers (GPC) failed, followed six minutes later by a second GPC. Mission Control decided to delay the landing until the crew could fix the problem. Young and Shaw brought the second GPC back up but had no luck with the first. Meanwhile, one of Columbia’s Inertial Measurement Units, used for navigation, failed. Finally, after eight hours of troubleshooting, the astronauts fired the shuttle’s Orbital Maneuvering System engines to begin the descent from orbit. Young piloted Columbia to a smooth landing on a lakebed runway at Edwards Air Force Base in California’s Mojave Desert, completing 166 orbits around the Earth in 10 days, 6 hours, and 47 minutes, at the time the longest shuttle flight. Shortly before landing, a hydrazine leak caused two of the orbiter’s three Auxiliary Power Units (APU) to catch fire. The fire burned itself out, causing damage in the APU compartment but otherwise not affecting the landing. The astronauts safely exited the spacecraft without incident. On Dec. 14, NASA ferried Columbia back to KSC to remove the Spacelab module from the payload bay. In January 1984, Columbia returned to its manufacturer, Rockwell International in Palmdale, California, where workers spent the next two years refurbishing NASA’s first orbiter before its next mission, STS-61C, in January 1986.

The journal Science published preliminary results from Spacelab 1 in their July 13, 1984, issue. The two Spacelab modules flew a total of 16 times, the last one during the STS-90 Neurolab mission in April 1998. The module that flew on STS-9 and eight other missions is displayed at the Stephen F. Udvar-Hazy Center of the Smithsonian Institution’s National Air and Space Museum in Chantilly, Virginia, while the other module resides at the Airbus Defence and Space plant in Bremen, Germany, not on public display.
