CNN —After completing 72 historic flights on Mars over three years, NASA’s Ingenuity helicopter mission has ended. NASA/JPL-CaltechThe NASA mission team only expected the chopper to carry out five test flights in 30 days. The chopper flew over areas of scientific interest to capture images and help the mission team determine Perseverance’s next targets for detailed analysis. “The Mars helicopter would have never flown once, much less 72 times, if it were not for the passion and dedication of the Ingenuity and Perseverance teams. History’s first Mars helicopter will leave behind an indelible mark on the future of space exploration and will inspire fleets of aircraft on Mars — and other worlds — for decades to come.”

CNN —An innovative experiment flying aboard NASA’s Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo was designed to be the US space agency’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser. NASA/JPL-CaltechIt’s not the first time laser communications have been tested in space. The first test of two-way laser communication occurred in December 2021 when NASA’s Laser Communications Relay Demonstration launched and went into orbit about 22,000 miles (35,406 kilometers) from Earth. And the Artemis II spacecraft will use laser communications to return high-definition video of a crewed journey around the moon.

☆ Solar conjunction halts communications between Mars missions and NASA
▼ + stars: | 2023-11-15 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

CNN —Robotic explorers investigating Mars are currently out of touch with space agencies on Earth after hitting a giant communications roadblock. Mission controllers at NASA won’t send any commands to its fleet of orbiters and rovers, including Perseverance and Curiosity, for the next 10 days due to the Mars solar conjunction. During the roughly two-week period, the hot, energized gas continually spewed by the sun from its outer atmosphere can interfere with the radio signals that NASA uses to communicate with its Martian robotic explorers. A Mars solar conjunction occurs every two years when the sun moves between Mars and Earth. The Ingenuity helicopter, which has largely served as the Perseverance rover’s aerial scout, will also lie low and won’t conduct any flights during this time.

CAPE CANAVERAL, Fla. (AP) — NASA’s Psyche spacecraft rocketed away Friday on a six-year journey to a rare metal-covered asteroid. SpaceX launched the spacecraft into an overcast midmorning sky from NASA’s Kennedy Space Center. Scientists envision spiky metal craters, huge metal cliffs and metal-encrusted eroded lava flows greenish-yellow from sulfur — “almost certain to be completely wrong,” according to Elkins-Tanton. Led by Arizona State University on NASA’s behalf, the $1.2 billion mission will use a roundabout route to get to the asteroid. So instead of arriving at the asteroid in 2026 as originally planned, the spacecraft won’t get there until 2029.

☆ Mars is rotating more quickly, NASA mission finds
▼ + stars: | 2023-08-14 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

CNN —Mars is rotating more quickly than it used to, according to data that NASA’s InSight lander collected on the red planet. Initially, the InSight mission, the first to study the interior of Mars, was supposed to last about two years after it landed in November 2018. The InSight mission continued to collect data about Mars until the very end, falling silent in December 2022 after dust blocked its solar panels from receiving sunlight. Researchers then used RISE to measure the wobble of Mars as the core sloshes around inside it. This new figure was compared with previous estimates of the core’s radius that were collected by tracking seismic waves as they traveled through Mars’ interior.

☆ NASA’s ‘shout’ restores communication with Voyager 2
▼ + stars: | 2023-08-04 | by ( Ashley Strickland | ) edition.cnn.com time to read: +3 min

CNN —Using a long-shot “shout” maneuver, the Voyager mission team at NASA has reestablished communication with Voyager 2 after losing contact with the spacecraft, which has been operating for nearly 46 years. Commands sent to Voyager 2 on July 21 accidentally caused the spacecraft’s antenna to point 2 degrees away from Earth. One radio antenna is located at Goldstone near Barstow, California, the second near Madrid, and the third near Canberra, Australia. It’s not the first time that the aging twin probes — Voyager 1 and Voyager 2, both launched in 1977 — have experienced issues. Voyager 1, which is nearly 15 billion miles (24 billion kilometers) from Earth, continues to operate as expected and communicate with the Deep Space Network.

It took an interstellar “shout” across the solar system. But NASA’s Jet Propulsion Laboratory said on Friday that it re-established full communications with Voyager 2, an aging probe exploring the outer edges of the solar system. “After two weeks of not hearing anything, we’re back to getting unique data from the interstellar medium,” said Linda Spilker, a planetary scientist at the Jet Propulsion Laboratory and the lead mission scientist for Voyager 2. On Tuesday morning, officials from the Deep Space Network, a worldwide system of radio dishes NASA uses to communicate with various space probes, detected a carrier signal known as a heartbeat from Voyager 2. Nonetheless, being able to pick up only the heartbeat “was upsetting and worrisome,” said Suzanne Dodd, the project manager for Voyager 2.

CNN —The Voyager mission team at NASA has been able to detect a signal from Voyager 2 after losing contact with the spacecraft, which has been operating for nearly 46 years. One radio antenna is located at Goldstone near Barstow, California, the second near Madrid, and the third near Canberra, Australia. “We are now generating a new command to attempt to point the spacecraft antenna toward Earth,” Dodd said. Along the way, both Voyager 1 and 2 have encountered unexpected issues and dropouts, including a seven-month period where Voyager 2 and the Deep Space Network couldn’t communicate in 2020. Meanwhile, Voyager 1, which is nearly 15 billion miles (24 billion kilometers) from Earth, continues to operate as expected and communicate with the Deep Space Network.

CNN —When NASA’s next-generation space observatory launches in a few years, the Nancy Grace Roman Space Telescope will expand the search for exoplanets as well as rogue planets, or worlds that travel through space without orbiting stars. Understanding these rogue planets could shed more light on the formation, evolution and disruption of planetary systems. This illustration shows what the Nancy Grace Roman Space Telescope will look like in orbit. But rogue planets are likely much smaller. Telescopes like Hubble and the James Webb Space Telescope have enabled astronomers to observe large, glowing gas giant exoplanets called hot Jupiters.

Dan Goods/NASA/JPL-CaltechThe transmission was incredibly slow by today’s standards, given that the Perseverance rover regularly sends back batches of high-resolution images from Mars. Together, they revealed craters on the Martian surface and clouds floating above in the atmosphere, both of which surprised scientists. The highest-resolution Mariner 4 image (right) revealed the cratered Martian surface from 7,830 miles (12,601 kilometers) above.

CNN —Humans’ unquenchable thirst for groundwater has sucked so much liquid from subsurface reserves that it’s affecting Earth’s tilt, according to a new study. That shift is even observable on Earth’s surface, as it contributes to global sea level rise, researchers reported in the study published June 15 in the journal Geophysical Research Letters. Seo and his colleagues had questions about long-term changes to the axis — specifically, how groundwater contributed to that phenomenon. Revealing groundwater extraction’s impactShifts in Earth’s axis are measured indirectly through radio telescope observations of immobile objects in space — quasars — using them as fixed points of reference. The redistribution of groundwater tilted Earth’s rotational axis east by more than 31 inches (78.7 centimeters) in just under two decades, according to the models.

Instead, the exoplanet, called LP 791-18 d, is likely covered in volcanoes and may experience eruptions with the same frequency as Jupiter’s moon Io, the most volcanically active place in our solar system, according to researchers. LP 791-18 d is located about 90 light-years from Earth in the Crater constellation, where it orbits a small red dwarf star. And astronomers believe the massive planet LP 971-18 c might be contributing to the newly detected exoplanet’s possible volcanism. As the two objects orbit their star, LP 971-18 c and the newfound exoplanet LP 791-18 d closely pass each other, allowing the gravitational pull of the larger planet LP 971-18 c to tug on planet d and reshape its orbit. The discovery of LP 971-18 d points to the importance of data collected by space telescopes.

☆ Petermann Glacier in Greenland is melting away with the tide, which could signal faster sea level rise, study finds
▼ + stars: | 2023-05-08 | by ( Brandon Miller | Cnn Meteorologist | ) edition.cnn.com time to read: +2 min

CNN —A major glacier in northwest Greenland is interacting with the ocean tides, scientists reported Monday, resulting in previously unaccounted-for melting and potentially faster sea level rise. This is an important finding: The traditional view among scientists was that the grounding line did not migrate with the tides – and this introduces another major source of melting that could be accelerating sea level rise. Between 2016 and 2022, warmer tidal cycles melted a 670-foot-tall hole in the underside of the glacier along the grounding line — big enough that two Statues of Liberty could be stacked on top of one another inside it. The study raises more concerns for the already worrisome prospect of sea level rise, which threatens coastlines around the world. Greenland’s melting ice is the single largest contributor to sea level rise, according to NASA, which has been accelerating in recent years.

CNN —China’s Zhurong rover on Mars has been in hibernation since last May due to an “unpredictable accumulation” of dust, mission designer Zhang Rongqiao said, Chinese state broadcaster CCTV reported on Tuesday. “According to our analysis, the biggest possibility is that because of unpredictable accumulation of Martian dust, its power generation capacity was reduced and it was too low to wake itself up,” Rongqiao said, explaining why the rover has since been dormant. This image showing the rover and the lander on the surface of Mars was taken by a separable camera deployed by the Zhurong rover in 2021. The NASA InSight lander’s mission came to an end in December after spending nearly 1,500 days on Mars. But a heavy accumulation of dust on its solar panels caused a steady drop in the lander’s power source.
