Image revives hopes of solving Amelia Earhart mystery

Update: The object that Deep Sea Vision thought was wreckage from Amelia Earhart’s plane turns out to be a rock formation.

What happened to Amelia Earhart, the famed aviator whose plane disappeared in 1937 as she was trying to fly around the world? After surveying 5,200 square miles of the Pacific Ocean, searchers say they may have picked up the sonar signature of Earhart’s sunken aircraft.

If their hypothesis holds up, the find could well solve one of the aviation world’s greatest mysteries. But if it doesn’t hold up, it wouldn’t be the first dead end in the 87-year-long search.

The 90-day sonar survey was conducted last year by Deep Sea Vision, a team of underwater archaeologists and robotics experts led by Tony Romeo, a former Air Force intelligence officer who reportedly sold his  real estate investments to fund the $11 million expedition.

In a news release issued today, Deep Sea Vision said it made use of a customized underwater robot to search wide swaths of the ocean floor with side-scan sonar. As the survey was winding up, the team identified a blurry shape that appeared to match the dimensions of Earhart’s twin-engine Lockheed 10-E Electra.

“You’d be hard-pressed to convince me that’s anything but an aircraft, for one; and two, that it’s not Amelia’s aircraft,” Romeo said on NBC’s “Today” show.

Zeno Power strikes a deal to recycle radioactive material

Zeno Power says it has gained access to radioactive material destined for its first full-scale radioisotope power systems under the terms of a partnership with the U.S. Department of Energy.

The transfer of the material from Oak Ridge National Laboratory in Tennessee benefits Zeno as well as the Department of Energy: Zeno — which has offices in Seattle and Washington, D.C. — gets the strontium-90 fuel that it needs for its next-generation RPS. At the same time, the DOE gets an opportunity to put a decades-old RPS to good use instead of putting it through a costly disposal process.

“This transfer highlights another unique approach our team has taken to accelerate environmental cleanup at Oak Ridge,” Jay Mullis, manager of DOE’s Oak Ridge Office of Environmental Management, said today in a news release. “This is a win-win scenario that’s removing a significant source of radioactivity at a savings to taxpayers, while also supporting nuclear innovation.”

Radioisotope power systems, also known as radioisotope thermoelectric generators or RTGs, have been used for decades to provide off-grid power for space missions and other applications. Such devices convert the heat generated by radioactive decay into electricity. Plutonium-238 is often used for space applications, but Zeno is working on a system that uses strontium-90 as an alternative heat source.

Nearly three years after the first-ever takeoff from the surface of Mars, NASA’s Ingenuity helicopter has landed for the last time.

The innovative mini-copter was brought to the Red Planet in 2021 as an experimental piggyback payload tucked beneath the Perseverance rover, and conducted 72 reconnaissance flights that racked up 11 miles of total distance and two hours of total flight time.

Not bad for a 4-pound gadget that was designed to fly only five times during a 30-day primary mission.

In a video tribute released today, NASA Administrator Bill Nelson called Ingenuity “the little helicopter that could.”

“It kept saying, ‘I think I can, I think I can,'” Nelson said. “Well, it has now taken its last flight on Mars.”

Japan’s power-starved moon lander is lying on its side

Update for Jan. 30: The sideways solar cells on Japan’s SLIM moon lander soaked up enough sunlight to allow for the robot’s revival on Jan. 28. SLIM is gathering up science data, including a closeup image of a lunar rock called Toy Poodle, but the power drain is expected to resume Feb. 1 when the 14-day-long lunar night begins.

Now we know why Japan’s lunar lander wasn’t able to recharge its batteries after touching down on the moon last week: The spacecraft appears to have tumbled onto its side, with its solar cells facing away from the sun.

The good news is that the Smart Lander for Investigating Moon, or SLIM, achieved its primary mission of setting down within 100 meters (330 feet) of its target point — and that the mission’s two mini-probes, which were ejected during SLIM’s descent, are working as intended.

Scores of images were taken before and after landing. One of the pictures. captured by a camera on the ball-shaped LEV-2 mini-probe, shows the lander sitting at an odd angle with its thrusters facing upward and its solar cells facing westward.

To conserve battery power, mission managers at the Japan Aerospace Exploration Agency shut down SLIM after the probes transmitted the imagery they collected. But there’s still a chance that the sun’s shifting rays could provide enough power to allow for further operations in the week ahead.

Scientists visit the kind of lake where life may have arisen

Several years ago, scientists at the University of Washington theorized that key ingredients for life could have built up billions of years ago in special kinds of environments known as soda lakes.

At the time, their hypothesis was based on previously published research, computer modeling and lab experiments. But now the same scientists say they’ve found a shallow lake that just might fit the requirements — and it happens to be just a few hundred miles north of their home base in Seattle.

Their findings, focusing on Last Chance Lake in British Columbia, were published this month in Communications Earth & Environment, an open-access, peer-reviewed scientific journal.

Zeno and Westinghouse team up on nuclear batteries

Zeno Power says it has selected Westinghouse Electric Co. to process the radioisotopes for its heat sources — creating a partnership that adds a key puzzle piece to its plan for a new type of radioisotope power system, or RPS.

“Working with Westinghouse, we will build the nuclear hardware for our RPSs to provide reliable power in the most critical domains of the 21st century — from the depths of the oceans to the surface of the moon,” Zeno co-founder and CEO Tyler Bernstein said today in a news release.

Radioisotope power systems that convert heat into electricity for off-grid power have been used for decades — for example, for space missions ranging from the Apollo moonshots to the Curiosity rover mission to Mars and the New Horizons mission to Pluto. Those systems have typically used plutonium-238, but Zeno is working on systems that make use of other radioisotopes such as strontium-90.

Strontium-90, which is created as a byproduct in nuclear fission reactors, can be an abundant fuel for power-generating systems. Existing strontium-based power systems tend to be bulky, however. Zeno’s design could generate more power with less bulk, opening the way for a wider range of applications.

Japanese robot lands on the moon but faces power drain

Update for Jan. 21: The Japan Aerospace Exploration Agency said it shut down its moon lander to conserve battery power, but added that the lander might be recharged and revived if sunlight hits the spacecraft’s solar cells at the right angle.

Japan has become the fifth nation to land a functioning robot on the moon, but the mission could fall short of complete success due to a problem with the lander’s power-generating solar cells.

The Smart Lander for Investigating Moon, or SLIM, was launched along with an X-ray space telescope called XRISM from Japan’s Tanegashima Space Center in early September — and after weeks of in-space maneuvers, SLIM touched down today at 1520 GMT (7:20 a.m. PT Jan. 19, or 12:20 a.m. JST Jan. 20).

The Japan Aerospace Exploration Agency reported that the landing was successful. During a news briefing, Hiroshi Kuninaka, director general of JAXA’s Institute of Space and Astronautical Science, said the achievement marked “a major milestone” in Japan’s effort to send spacecraft to the moon, and eventually to Mars.

Kuninaka said SLIM was able to communicate with Earth and respond to commands. “However, it seems that the solar cells are not generating electricity at this point in time,” he said. “And since we are not able to generate electricity, the operation is being done using batteries alone.”

Lander falls back to Earth after missing out on the moon

Ten days after its launch, Astrobotic’s Peregrine lunar lander fell back to Earth, ending a trip to the moon’s orbital distance and back that was doomed by a propellant leak.

The mission began auspiciously on the night of Jan. 7-8 with a seemingly successful liftoff from Florida on United Launch Alliance’s first Vulcan Centaur rocket, powered by Blue Origin’s BE-4 rocket engines. But hours after launch, the Pittsburgh-based Astrobotic team detected a problem with the propulsion system. So much propellant was lost that the team had to rule out a moon landing.

After days of troubleshooting, Astrobotic and NASA determined that the best course was to send the 8-foot-wide robotic spacecraft on a looping orbit that went out more than 240,000 miles from Earth — and then came back for a controlled atmospheric re-entry over a remote area of the South Pacific.

Astrobotic said telemetry received during Peregrine’s descent suggested that the spacecraft broke up during re-entry at 1:04 p.m. PT Jan. 18.

Today, Space-Track.org said the U.S. Space Command confirmed the spacecraft’s re-entry. “That’s certainly good to hear,” Astrobotic CEO John Thornton told reporters during a news briefing.

“Peregrine Mission One has concluded,” Astrobotic said in a final mission update. “We look to the future and our next mission to the moon, Griffin Mission One. All of the hard-earned experience from the past 10 days in space, along with the preceding years of designing, building and testing Peregrine, will directly inform Griffin and our future missions.”
