NASA Pauses Attempts to Fix Lucy’s Pesky Solar Array
NASA is taking a break from attempts to unfurl a finicky solar array on the Lucy spacecraft, claiming that the probe is too cold and that efforts at deploying the array could be more fruitful when Lucy is closer to the Sun in December 2024.
After launching in October 2021, one of the spacecraft’s two 24-foot-wide (7-meter-wide) solar arrays, which supplies power to Lucy, failed to fully unfurl, remaining stuck in an unlatched position. While NASA has made previous attempts to fully deploy the array, the agency announced in a blog post that the Lucy team will be suspending attempts to completely unfurl the array, saying the spacecraft is too cold.
That said, NASA’s not sweating the issue, and estimated in a blog post that the array is 98% deployed and will be able to withstand the remainder of Lucy’s 12-year mission to visit Jupiter’s mysterious Trojan asteroids, which orbit both ahead and behind the gas giant.

“Ground-based testing indicated that the deployment attempts were most productive while the spacecraft was warmer, closer to the Sun,” NASA communication officer Erin Morton wrote in the post last week. “As the spacecraft is currently 123 million miles (197 million kilometers) from the Sun (1.3 times farther from the Sun than the Earth) and moving away at 20,000 mph (35,000 km/hr), the team does not expect further deployment attempts to be beneficial under present conditions.”
NASA noticed issues with the solar array shortly after the mission’s launch, and deduced that it was a loss in tension in a lanyard used to unfurl the circular array. Lucy is now hurtling away from the Sun, getting colder and colder, but will return to Earth for a gravity assist in December 2024. At this time, the Lucy team hopes that spacecraft will be warm enough to try again.
In the meantime, the team behind Lucy will be collecting data on the misbehaving solar array to see how it operates at its slightly incapacitated state as Lucy continues its mission to visit Jupiter’s Trojan asteroid clusters.

Scientists look inside passing asteroid with HAARP antenna array
Scientists have used a former U.S. military research facility famous for weather control conspiracy theories to learn more about the interior of a passing asteroid.
The High-frequency Active Auroral Research Program (HAARP) is a range of 180 antennas located in Gakona, Alaska, capable of sending powerful high-frequency radio pulses into the sky and beyond. Built by the U.S. Air Force and the U.S. Navy in the 1990s, the facility became an object of conspiracy theories with some claiming it’s being used to control weather or induce natural disasters including earthquakes.
In reality, scientists have been using HAARP to probe the ionosphere, the upper region of Earth’s atmosphere that interacts with plasma and electromagnetic radiation coming from the sun. In 2015, the facility was transferred from the ownership of the U.S. Air Force to the University of Alaska, Fairbanks, which has recently announced a range of experiments looking beyond Earth’s gaseous blanket.
Related: Space geoengineering: Can we control the weather?
One of these experiments, conducted in late December, involved shooting powerful pulses of long radio waves at an asteroid that was passing Earth at a distance double that of the moon at the time. The experiment aimed to learn about the interior of the asteroid, which could one day help design an effective Earth-saving mission in case this or another space rock were to intersect our planet’s path.
“We will be analyzing the data over the next few weeks and hope to publish the results in the coming months,” Mark Haynes, lead investigator on the project and a radar systems engineer at NASA’s Jet Propulsion Laboratory in Southern California, said in a statement (opens in new tab). “This experiment was the first time an asteroid observation was attempted at such low frequencies.”
The asteroid, known as 2010 XC15, is about 500 feet wide (150 meters) and classified as potentially hazardous, which means it makes regular close approaches to Earth and could possibly one day hit the planet.
Gathering data about the distribution of matter inside the asteroid could help engineers design a more effective deflection mission if it was ever needed. NASA tested such an approach in September last year when its Double Asteroid Redirection Test (DART) spacecraft successfully changed the orbit of an asteroid moonlet Dimorphos around its parent space rock Didymos. DART, however, smashed into Dimorphos while its ground controllers knew barely anything about the rock. If our home planet were really at risk, its defenders would want to avoid going into the unknown by gaining an understanding of any asteroids prior to launching impactors at them.
During the experiment, conducted on Dec. 27, HAARP kept firing radio waves at 2010 XC15 for 12 hours. Scientific radio antennas including those operated by amateurs all over the world listened for the returning signals to help understand the environment the signals traveled through as well as the properties of the asteroid.
“So far we have received over 300 reception reports from the amateur radio and radio astronomy communities from six continents who confirmed the HAARP transmission,” Jessica Matthews, HAARP’s program manager, said in the statement.
The most common methods of studying asteroids involve either optical telescopes or radio telescopes transmitting radiation with much shorter wavelengths. Neither of these techniques, however, can peer inside an asteroid, the researchers said in the statement. Optical telescopes only receive visual information from the light naturally reflected by the asteroids, while radio pulses with shorter wavelengths bounce off the space rocks’ surfaces, only revealing information about their outer shapes.
The HAARP team has previously run experiments targeting the moon and the solar system’s largest planet Jupiter.

Construction Begins on Square Kilometer Array Radio Telescope
The world’s largest radio telescope is officially under construction in Australia, where work is underway on one component of what will be an intercontinental instrument. When operational in the late 2020s, the telescope will offer a sharper, wider view of the universe in radio wavelengths.
The telescope is called the Square Kilometer Array, a reflection of scientists’ original goal of having a collecting surface of a square kilometer; the actual SKA will have a collecting area of half a square kilometer. According to an SKA Observatory release, teams celebrated the commencement of construction with ceremonies at project locations in Australia and South Africa.
The array will be a combination of nearly 200 radio dishes and 130,000 dipoles, which are smaller, ground-based antennae. In other words, the SKA is one big telescope made up of many smaller telescopes.
The array’s radio dishes will be located in South Africa’s Karoo Desert, and its Christmas-tree-shaped antennae will be situated deep in the Western Australian outback. Radio telescopes need radio silence to be able to focus on the long wavelengths from deep space, which is why the SKA’s organizers chose these remote set-ups.
Having such massive scientific instruments in wild places doesn’t come without difficulties. In Australia, ants can fry the electronics, and termites build mounds around telescope antennae. Kangaroos occasionally kick over existing instruments, and giant lizards named Steve walk around the arrays like they own the place. And given the near-total absence of humans, they kind of do.
Numerous predecessors to the SKA exist already, including the MeerKAT array in South Africa, which took a stunning image of the ‘threads’ in the galactic center. But only now are pieces of the SKA’s core being constructed, after years of design and planning. The completed SKA is expected to be operational in the late 2020s.
Bigger telescope arrays offer better resolution—hence the excitement surrounding what will be the world’s largest radio telescope array.
“To put the sensitivity of the SKA into perspective, the SKA could detect a mobile phone in the pocket of an astronaut on Mars, 225 million kilometers away,” Danny Price, a senior research fellow at the Curtin Institute of Radio Astronomy, told AFP.
The SKA will observe massive compact objects like pulsars and black holes to better understand gravitational waves, as well as the epoch of reionization, when the first galaxies and stars appeared, and the first billion years of the universe.
The Webb Space Telescope is also looking at some of the universe’s earliest light, but it observes at the infrared and near-infrared wavelengths, rather than at the much longer radio wavelengths.
Combine these cutting-edge observatories with the number of new space missions set to launch at the turn of the decade, and it’s clear that we’re in for some very interesting astrophysical insights in the years ahead.

Astronauts install new solar array outside International Space Station – Spaceflight Now
NASA astronauts Josh Cassada and Frank Rubio headed outside the International Space Station Saturday for a seven-hour spacewalk to install and unfurl a new roll-out solar array recently delivered by a SpaceX cargo ship.
Cassada and Rubio, both on their first flights to space, began the spacewalk at 7:16 a.m. EST (1216 GMT) Saturday. The start of the excursion was officially marked when the astronauts switch their spacesuits to battery power.
The astronauts moved from the space station’s Quest airlock to the starboard, or right, side of the lab’s solar power truss, where the station’s robotic arm placed two new ISS Roll-Out Solar Array, or iROSA, units earlier this week after extracting them from the trunk of a SpaceX Dragon cargo capsule. The Dragon spacecraft delivered the solar arrays to the space station Nov. 27, along with several tons of supplies and experiments.
The new solar array blankets were wrapped around spools and unrolled like a yoga mat once installed onto a mounting bracket on the starboard 4, or S4, section of the space station’s power truss, which measures more than the length of a football field from end-to-end.
The astronauts initially worked to remove one of the two newly-delivered iROSA units from its carrier by releasing bolts and launch restraints. Cassada took position on a foot restraint on the end of the Canadian-built robotic arm, and held the solar array spools by hand while the arm moved him to the S4 truss.
The two spacewalkers positioned the iROSA unit onto a mounting bracket pre-positioned during a previous spacewalk. They unfolded the iROSA unit on its hinge, then installed bolts to secure it into place. Cassada and Rubio mated electrical connectors to link the new iROSA unit to the space station’s electrical system. Then they put in a Y cable to route power generated by both the new roll-out solar array and the original S4 solar panel into the lab’s power grid.
The mounting bracket plugs the new arrays into the station’s power channels and rotary joints, which keep the solar wings pointed at the sun as the spacecraft races around Earth at more than 17,000 mph.
The International Space Station has eight power channels, each fed with electrical power generated from one solar array wing extending from the station’s truss backbone. The new solar array deployed Saturday will produce electricity for the space station’s 3A power channel.
The original solar panels launched on four space shuttle missions from 2000 to 2009. As expected, the efficiency of the station’s original solar arrays has degraded over time. NASA is upgrading the space station’s power system with the new roll-out solar arrays — at a cost of $103 million — which will partially cover six of the station’s eight original solar panels.
When all six iROSA units are deployed on the station, the power system will be capable of generating 215 kilowatts of electricity to support at least another decade of science operations. The enhancement will also accommodate new commercial modules planned to launch to the space station.
The first pair of new roll-out solar arrays launched to the space station last year, and were installed over the station’s oldest set of original solar panels on the P6 truss section, located on the far left end of the outpost’s power truss. Two more iROSA units are slated to launch on a SpaceX resupply mission next year.
The new solar arrays were supplied to NASA by Boeing, Redwire, and a team of subcontractors.
Once the new iROSA unit was mechanical and electrically integrated onto the station’s S4 truss, the astronauts released clamps keeping the roll-out solar array spooled in its launch configuration. That allowed the blankets to gradually unroll using strain energy in the composite booms supporting the solar blanket. The design of the deployment mechanism eliminates the need for motors to drive the solar array.
“It’s starting to move,” one of the astronauts radioed mission control, prompting applause among the support team in Houston.
“That is incredible,” Cassada said. “Yeah, it’s pretty cool,” Rubio chimed in.
The carbon fiber support booms were rolled back against their natural shape for storage during launch.
It took about 10 minutes for the solar array to unroll to its fully extended configuration, stretching about 63 feet long and 20 feet wide (19-by-6 meters). That’s about half the length and half the width of the station’s current solar arrays. Despite their smaller size, each of the new arrays generate about the same amount of electricity as each of the station’s existing solar panels.
Once the blanket unfurled, the astronauts adjusted tensioning bolts to secure the iROSA blanket in place.
Then the astronauts headed back in-board on the space station’s truss to prep another iROSA unit, which will be installed on the left-side P4 truss section on a spacewalk tentatively scheduled for Dec. 19.
With their tasks complete, Cassada and Rubio made their way back to the Quest airlock and closed the hatch. They started repressurizing the airlolk compartment at 2:21 p.m. EST (1921 GMT), completing the 7-hour, 5-minute spacewalk.
The spacewalk Saturday was the second in the careers of Cassada and Rubio, and the 256th spacewalk since 1998 in support of International Space Station assembly and maintenance.

Cygnus Spacecraft Reaches ISS With One Functioning Solar Array
The S.S. Sally Ride has safely docked at the International Space Station following a nail-biting journey in which one of its two solar arrays failed to deploy.

Northrop Grumman’s expendable freighter launched on Monday, November 7, carrying 8,200 pounds of cargo to the ISS. On its way to the orbiting space station, however, the Cygnus capsule failed to deploy one of its two solar arrays, which collects power for its trip through space. “Northrop Grumman is gathering data on the second array deployment and is working closely with NASA,” the space agency wrote in a blog post on Monday.
Despite having only one fully unfurled solar array, the Cygnus spacecraft safely arrived at the ISS on Wednesday at 5:20 a.m. ET, according to a NASA blog post. As the cargo capsule approached the station, NASA astronaut Nicole Mann used the Canadarm2 robotic arm to grab the vehicle and maneuver it towards the station’s docking port. This is standard procedure for capturing Cygnus and not the result of the solar panel anomaly.
The 55-foot-long (17-meter) Canadian arm features a “hand” that astronauts use to grab onto objects and even the ISS itself. After Mann commanded the robotic arm from inside the ISS, ground controllers took over to guide the capsule and dock it at the station’s Unity module, NASA wrote.

A reason for the malfunction has not yet been disclosed. “To remain focused on the spacecraft’s arrival at the station, Northrop Grumman and NASA made the determination not to deploy the second solar array after initial attempts to deploy it were unsuccessful,” the space agency said.
This is Northrop Grumman’s 18th resupply mission to the ISS as part of its Commercial Resupply Services contract with NASA, in which it delivers crew supplies, equipment, and science experiments to the orbiting station. The NG-18 Cygnus spacecraft was named after Sally Ride, the first U.S. woman to reach space, a feat she accomplished in 1983.
The cargo capsule delivered a diverse payload that includes a 3D printer for generating human tissues, an experiment on growing plants in space, and the first satellite developed by Uganda and Zimbabwe. The freighter will stay attached to the ISS until its fiery disposal in the Earth’s atmosphere in January.

Cygnus Fails to Deploy Solar Array Shortly After Launch
The Cygnus cargo spacecraft has run into some trouble on its way to the International Space Station (ISS), as one of its two solar arrays is refusing to deploy.
Northrop Grumman’s Cygnus spacecraft had an early launch on Monday, November 7 at 5:32 a.m. ET from Virginia Space’s Mid-Atlantic Regional Space Port. The expendable freighter is carrying 8,200 pounds of cargo to the ISS and is scheduled to arrive at the orbiting space station on Wednesday.
While en route, the cargo capsule experienced a slight malfunction. After separating from the Antares rocket, Cygnus only managed to deploy one of its solar arrays while the other one remained unfurled. “Northrop Grumman is gathering data on the second array deployment and is working closely with NASA,” the space agency wrote in a very short blog post on Monday.
That said, Northrop Grumman did inform NASA that Cygnus, despite having only one functioning solar array, has enough power to continue the rest of its journey and rendezvous with the ISS on Wednesday. “NASA is assessing this and the configuration required for capture and berthing,” NASA added.
The NG-18 resupply mission to the ISS is meant to deliver crew supplies, equipment, and science experiments to the orbiting station. Cygnus is part of Northrop Grumman’s commercial contract with NASA, delivering cargo resupply missions to the ISS.

Cygnus cargo ship trying to reach ISS with only 1 solar array deployed
A private cargo ship’s trip to the International Space Station (ISS) isn’t going as planned.
Northop Grumman’s robotic Cygnus cargo ship launched toward the ISS this morning (Nov. 7) from Virginia, packed with more than 4.1 tons (3.7 metric tons) of food and other supplies for the astronauts aboard the orbiting lab.
The launch went smoothly, but Cygnus encountered some trouble after separating from its Antares rocket ride: The freighter has managed to unfurl just one of its two solar arrays.
Mission team members are working to troubleshoot the glitch, but Cygnus may still be able to power its way to the space station for a scheduled Wednesday (Nov. 9) meetup even if a fix isn’t found.
“Northrop Grumman has reported to NASA that Cygnus has sufficient power to rendezvous with the International Space Station on Wednesday, Nov. 9, to complete its primary mission, and NASA is assessing this and the configuration required for capture and berthing,” NASA officials wrote in a brief update today (opens in new tab).

This Cygnus vehicle, named the SS Sally Ride after the first American woman to reach space, will deliver more payload by mass to the ISS than any previous Northop Grumman freighter, if all goes as planned.
SS Sally Ride’s cargo manifest includes 3,608 pounds (1,637 kilograms) of crew supplies, 2,375 pounds (1,077 kg) of vehicle hardware, 1,873 pounds (850 kg) of science gear, 145 pounds (66 kg) of spacewalk equipment and 172 pounds (78 kg) of computer resources, NASA officials said.
Among the many science experiments flying on the cargo ship is a 3D printer known as the BioFabrication Facility (opens in new tab), which is designed to print organ-like tissues in microgravity, and a study that will assess how the space environment affects ovarian cells.
Cygnus is one of three robotic spacecraft that currently ferry cargo to the ISS, along with Russia’s Progress vehicle and SpaceX’s Dragon capsule.
Cygnus and Progress are expendable craft that burn up in Earth’s atmosphere when their time in orbit is up. Dragon, by contrast, returns to Earth in one piece for future reuse.

Huge HAARP antenna array is bouncing radio signals off Jupiter
The High-frequency Active Auroral Research Program facility, or HAARP, is in the midst of a wide-ranging science campaign that will see the facility bounce signals off the moon and Jupiter.
HAARP consists of 180 antennas designed to transmit signals into the ionosphere, which stretches from 30 miles (48 kilometers) to 600 miles (965 km) above sea level and is seen as the area where Earth’s atmosphere meets space, according to NASA (opens in new tab). The ionosphere plays an important role in radio transmission, as it reflects radio waves. Many satellites occupy this region of the atmosphere, which is heavily influenced by solar weather.
HAARP is in the midst of a 10-day research campaign that is the facility’s “largest and most diverse to date,” HAARP program manager Jessica Matthews said in a statement (opens in new tab). Among the 13 experiments being conducted during the campaign are projects that will see signals bounced off the moon and Jupiter in order to test HAARP’s ability to study objects far from Earth.

One of the most ambitious experiments being carried out during HAARP’s current campaign is known as “Jupiter Bounce,” or “Interplanetary Ionosonde,” according to a statement from the University of Alaska Fairbanks (UAF) (opens in new tab). The experiment will test HAARP’s ability to bounce signals off the ionosphere of Jupiter, while also determining how well receivers at the University of New Mexico’s Long Wavelength Array can receive the reflected signals. The experiment is “the largest active remote sensing operation in history,” according to the UAF statement.
“This is a first-of-its-kind experiment (which) at least to my knowledge has never been attempted before,” HAARP research support services lead Evans Callis told Alaska Public Media (opens in new tab). “We transmit several different frequencies from HAARP directed at Jupiter. We listen for the echo that returns, and that should be able to tell us something about electromagnetic conditions around Jupiter.”
Another experiment, known as “Moon Bounce,” will see signals bounced off the moon back towards receivers in New Mexico and California. These signals will be evaluated for their use in determining the composition of near-Earth asteroids for future planetary defense purposes.
Meanwhile, HAARP’s “Making the Invisible Visible” experiment will “test if hot electrons are capable of producing the continuum (white) emissions present in STEVE airglow.” STEVE, short for Strong Thermal Emission Velocity Enhancement, is an aurora-like phenomenon that occurs when charged particles from the sun interact with Earth’s ionosphere.
“If we see that air glow and it matches the wavelength of light that we see from naturally occurring STEVE, that would give us indication that the hot electrons are playing some role in the formation of STEVE,” Callis said.

One of the more unique experiments, “Ghosts in the Airglow,” will mix art and atmospheric research to “play with the liminal boundaries of Earth’s atmosphere and outer space,” according to the project’s website (opens in new tab). The experiment will use HAARP to bounce images, spoken word and sound art off the ionosphere to learn more about radio propagation.
The HAARP facility was constructed in 1993 and originally operated by several United States military research agencies, including the Defense Advanced Research Projects Agency (DARPA), Air Force Research Laboratory and Office of Naval Research. In 2015, ownership of the facility was transferred to the UAF (opens in new tab).
While primarily used for upper-atmospheric research, the facility has been the subject of numerous conspiracy theories (opens in new tab) in the nearly three decades since it was constructed. Some have accused the U.S. government of using the facility to modify the weather, trigger earthquakes, create “chemtrails” or even to broadcast mind-control signals (opens in new tab).
To date, there has been no evidence of the facility being used for mind control or anything other than atmospheric research. According to the “Frequently Asked Questions” page on HAARP’s website (opens in new tab), “Neuroscience is a complex field of study carried out by medical professionals, not scientists and researchers at HAARP.”
