Japan's ispace blames 'hard landing' on moon on Laser Range Finder
June 24 (UPI) -- Japanese company ispace said Tuesday that a "hard landing" during its attempted lunar landing in early June was due to an anomaly in the Laser Range Finder.
In the analysis of the "SMBC X HAKUTO-R VENTURE MOON" mission 2 ispace said the hard landing was due to an "anomaly in the laser rangefinder hardware," and the telemetry data also revealed no issues with the lander's software or propulsion system.
The LRF unit did not provide altitude measurement until it was less than half a mile off the ground. However, it was initially designed to provide altitude data when the spacecraft was at at least about 2 miles above the surface.
Laser light reflected back to the lander, lower power of the laser, reduced performance at higher velocities or effects from the space environment, such as a vacuum or radiation are several factors that could have played a role in the performance of the LRF.
"On June 6, despite the united efforts and dedication of the ispace team, our second attempt at a lunar landing was unsuccessful, resulting in deep disappointment," said Founder and CEO of Ispace Takeshi Hakamada. "We deeply regret that we were unable to meet the expectations of our shareholders, payload customers, HAKUTO-R partners, government officials, and all others who supported us."
"Ispace will not let this be a setback. We will not stop here, but as determined pioneers of the cislunar economy, we will strive to regain the trust of all stakeholders and embark on the next mission.
Chief technology officer at ispace Ryo Ujiie said the company was taking major steps to combat the problem. One is to conduct a better testing plan to see how the laser rangefinder operates under different conditions. The second is to look into getting a different laser rangefinder.
These changes will not be in effect for missions 3 and 4, which are scheduled to launch in 2027.
"We take it very seriously," Takeshi Hakamada, chief executive of ispace, said of the failed landings of its first two missions. "However, the important part is that we keep trying. There can be some failures, but we keep improving our systems."
"Our primary goal today was to convey that ispace, as a challenger, is already moving forward towards its next mission," he said, vowing to regain the trust of its customers and other stakeholders. "We're committed to demonstrating that Ispace will continue to grow undeterred by this setback."

Panama president seeks support for vital Río Indio water project
July 3 (UPI) -- Panamanian President José Raúl Mulino urged member nations at the Mercosur Summit in Buenos Aires, to back the Río Indio project, a critical infrastructure effort to secure water supplies for the Panama Canal amid mounting climate change pressures. "I need the support not only of the users, but also of the international community, so this project, led by the Canal Authority, can succeed and move forward as quickly as possible," Mulino said Tuesday. Mercosur, short for Mercado Común del Sur, is a South American trade bloc formed in 1991 by Argentina, Brazil, Paraguay and Uruguay, whose main goal is to promote free trade and economic integration among member countries. The request followed similar appeals made days earlier during Mulino's official visit to Seville, where he discussed the project with Spain's King Felipe VI, emphasizing the urgency of building a reservoir to safeguard the canal's long-term sustainability. On the same trip, he also raised the issue with Ecuadorian President Daniel Noboa, noting that the project would benefit not only Panama, but also other canal users, including Chile and Ecuador. "The Canal is neutral, but its sustainability is a shared responsibility," Mulino said. The Río Indio project calls for building a multipurpose reservoir in central Panama, in the basin of the river of the same name. The reservoir would hold up to 55.7 billion cubic feet of water and flood an estimated 17.4 square miles. The plan includes a roughly 5-mile transfer tunnel to Gatún Lake, one of the Panama Canal's main water sources. The Panama Canal Authority says the reservoir would add 42.4 billion square feet of reliable water annually -- enough to support about 15 additional daily transits and bolster operations during prolonged droughts. The project carries an estimated cost of $1.6 billion, with at least $400 million allocated for social compensation, community resettlement and environmental mitigation. Mulino's international strategy seeks not just financial and diplomatic backing, but symbolic support, as well. In his remarks in Buenos Aires, Mulino referred to a January statement by U.S. President Donald Trump, who said he intended to "take back control" of the Panama Canal. Mulino thanked the international community for its support, saying, "The canal is and will remain Panama's -- a national asset that took 100 years to reclaim." As climate change intensifies, Panama faces the challenge of balancing national and international water demands with the rights and livelihoods of rural communities. The Río Indio project has sparked strong opposition from local farmers and social organizations. In May, more than 400 people held a symbolic protest, paddling canoes down the river in defense of their land and way of life. The canal authority has pledged a process that is "orderly, fair and transparent," and said no family will be relocated without prior consultation.

Red, white and blue on the Red Planet
July 3 (UPI) -- On the eve of the 249th anniversary of American independence, NASA on Tuesday showcased a patriotic image of Old Glory as seen from hundreds of millions of miles away. A plaque bearing the United States flag is on an aluminum plate at the base of the mast, or "head," of NASA's Perseverance rover on the Red Planet. An image of the flag was taken on June 28 by the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera on the end of the rover's robotic arm. On Tuesday, NASA published an image of the flag on the rover, as seen during its 1,548th day of its mission. WATSON was built by Malin Space Science Systems in San Diego and is operated jointly by Malin Space Science Systems and NASA's Jet Propulsion Laboratory in Southern California. JPL, managed by Caltech, built and manages operations of Perseverance. The first U.S. flag planted somewhere besides Earth was the one planted on the moon by Buzz Aldrin in 1969. It signaled the United States had won the so-called Space Race with the Soviet Union.

Criminal groups exploit Peru's small-scale mining registration program
Registered miners in Peru have had been given a deadline to submit documents, meet environmental and labor standards and transition to legal operations. But after four extensions, the process has failed to deliver many results. Photo by Tyna_Janoch/ Pixabay July 3 (UPI) -- The government of President Dina Boluarte has extended Peru's small-scale mining formalization program through December, even as doubts persist more than a decade after its launch and experts warn that criminal organizations have exploited the system. According to official figures from the Ministry of Energy and Mines, just 2,108 of the 86,000 miners enrolled in the Integral Registry for Mining Formalization, or REINFO, had completed the process as of November 2024 -- a rate of only 2.4%. REINFO was launched as part of a government effort to contain the unchecked growth of informal and illegal mining. It gave registered miners a deadline to submit documents, meet environmental and labor standards and transition to legal operations. But after four extensions, the process has failed to deliver lasting results. Energy and Mines Minister Jorge Montero said the situation could improve in the coming months. He noted that another 5% of registered miners are close to completing the formalization process, and added that the government aims to mediate agreements between concession holders and roughly 15,000 small-scale miners who are working informally on those sites. But experts say repeated deadline extensions have turned the program into a legal gray area that criminal groups exploit. "We're talking about a failed system by every measure," Mónica Muñoz-Nájar, an economist with the Red de Estudios para el Desarrollo, said in an interview with RPP. She pointed to the low rate of formalization and the expansion of informal mining. "Forty-four percent of the gold Peru exports comes from illegal mining, which has become more profitable than drug trafficking. It's estimated that illegal mining generates $12 billion a year," she said. One of the strongest criticisms of REINFO comes from the National Society of Mining, Petroleum and Energy. Its president, Julia Torreblanca, said the registry has become a "shield for illegality" and that its indiscriminate extensions distort the market by protecting individuals who have no intention of following the law or meeting formalization requirements. A growing concern, however, is the infiltration of organized crime into informal mining zones operating under REINFO's protection. Organizations such as the Observatory of Illegal Mining and advocacy group DAR have warned that criminal networks use the registry to operate unregulated mining fronts, traffic illegal gold, transport chemical supplies and even facilitate human trafficking and forced labor. These warnings align with reports from the National Police, who have identified criminal networks in regions including Madre de Dios, Puno and La Libertad. Authorities say these groups use informal mining concessions to conceal a range of illegal activities, including fuel smuggling, arms trafficking and the export of gold to international markets. In early May, police reported the kidnapping and murder of 13 private security guards employed by a contractor linked to the Poderosa mining company in the Pataz region. Authorities said the bodies showed signs of torture and were found bound and unclothed -- a sign of the extreme violence used by criminal gangs tied to illegal mining. The case marked a critical moment in Peru, underscoring the violence and criminal networks that operate alongside illegal mining in the Andes and the direct threat they pose to people working in the region. A recent report from the Pontifical Catholic University of Peru warns that illegal mining is one of the most destructive activities environmentally, socially and economically. It found that in regions like Madre de Dios, up to 50,000 hectares of forest have been destroyed. The state collected about $12,000 in taxes, compared with an estimated $565 million in extracted gold. Estimated tax evasion ranges from $85 million to $168 million.
