NASA launch crew rings NYSE closing bell
Several SPHEREx team members including flight system manager Michael Thelen rang the closing bell at the Wall Street exchange earlier in the week.
Members of London-based aerospace firm BAE Systems Inc. also participated in the closing bell ritual. The company provided the telescope and spacecraft bus for the mission.
The two-year SPHEREx mission aims to conduct an "all-sky spectral survey" using the near-infrared space observatory.
NASA built the explorer at its Joint Propulsion Laboratory at Vandenberg Space Force Base in California.
SPHEREx successfully launched aboard a SpaceX Falcon 9 rocket in March, marking the first dual launch in the private company's history.
The observatory "will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe," according to NASA's mission page.
The $488 mission will produce a three-dimensional map, which will take up to two years. Scientists expect it will give them more information about how the universe expanded so rapidly.

Electric boat used for fish surveys on River Thames
A unique boat is being used for important fish monitoring surveys along the River Thames. The Environment Agency is carrying out the work between Iffley Lock in Oxford and Teddington Lock in London using a specialised boom boat. The boat uses an electric field to temporarily immobilise fish, allowing officers to study the health of the river's fish population. Jonathan Baxter, team leader at the Environment Agency, said: "We undertake annual fish monitoring on the Thames and its tributaries. "We have a statutory duty to maintain, improve, and develop fisheries, and the Thames Trout makes what could be a tricky process an absolute doddle. The boat used to catch the fish (Image: The Environment Agency) "Surveys such as these provide extremely accurate data from our principal fisheries and can detect trends linked to factors such as climate change." Surveys are typically conducted at dusk when the river is quieter and fish rise closer to the surface, improving capture rates. The Thames Trout boom boat is equipped with the largest front-mounted underwater electrodes in the Environment Agency's fleet. These electrodes cover a wide area of the river, making the process more efficient. The electric field stimulates the fish's nervous system, causing them to swim towards the operator or leaving it unable to swim away. They are then netted and placed in aerated holding tanks to recover before being identified, measured, and released. A sea trout caught during the survey (Image: The Environment Agency) Mr Baxter said this year's warm weather seems not to have had an impact on fish populations. He said: 'Over 6,200 fish were caught in the 2024 survey between Iffley and Benson, with results showing an abundance of healthy fish. "We've surveyed over 10,000 this year and despite the recent dry weather, we have seen no significant impact to the Thames fish population, although as with any dry weather event, anglers should be mindful of the fish they are catching as some species may need a longer recovery period in extreme heat.' The fish populations in the River Thames provide an opportunity for people of all ages to get out and enjoy fishing on one of our country's largest rivers. Anyone aged 13 or older needs a licence to fish for salmon, trout, eels, or freshwater species. Information on when a licence is needed and how to buy one is available online on the UK Government website. Licences can also be bought by calling 0344 800 5386. The income from rod licences helps with the sustainable management of fisheries. The Environment Agency's fisheries enforcement officers check private lakes, rivers, ponds, and canals for illegal fishing, supported by clubs, the Angling Trust, and the police.

Congressperson Urges NASA to Send Its Jupiter Probe Chasing in Pursuit of the Weird Visitor Coming From Interstellar Space
Earlier this year, astronomers spotted a mysterious interstellar object, dubbed 3I/ATLAS, hurtling through the solar system at a blistering speed. It's only the third confirmed interstellar object to have ventured into our solar system — all over the past few years, owing to more sophisticated space-observing technology — and scientists are eager to have a closer look. Besides detailed observations by the Very Large Telescope in Chile and NASA's Hubble Space Telescope, Harvard astronomer and alien hunter Avi Loeb called on using the space agency's Juno spacecraft to intercept the object's path to get a first-hand look. Loeb, who made headlines last month after suggesting 3I/ATLAS may be an alien probe sent by an intelligent civilization, argued in a blog post that the "close encounter of 3I/ATLAS to Jupiter provides a rare opportunity to shift Juno from its current orbit around Jupiter to intercept the path of 3I/ATLAS at its closest approach to Jupiter." The unique opportunity caught the attention of Representative Anna Paulina Luna (R-FL), who sent a letter to acting NASA administrator Sean Duffy, encouraging the agency to follow Loeb's suggestion. "It is recommended that NASA conduct a study to assess how much fuel is left in Juno's engine, and I support an extension of the Juno mission at least until mid-March 2026 at a cost of about $15M per 6 months from the current expiration date of mid-September 2025," the letter reads. Experts, however, were quick to throw cold water on Loeb's plan, which happens to resemble the plot of Stanley Kubrick's 1968 sci-fi epic "2001: A Space Odyssey." "Juno does not have enough fuel to visit 3I/ATLAS," Penn State astronomy professor Jason Wright tweeted. "Its main engine is also malfunctioning. [Loeb] does (or should) know this because his team was in touch with [Juno principal investigator Scott Bolton]." "An extended mission for Juno would be awesome, but a visit to 3I/ATLAS makes no sense," he added. The spacecraft was launched almost exactly 14 years ago, entering a polar orbit of Jupiter roughly five years later. It was only planned to study the planet until 2018, but it has since doubled the length of its originally planned mission. Not everybody agrees that a mission to visit 3I/ATLAS is out of the question, though. Juno's "current orbit allows it to view Jupiter up close, and its visits to Io [a moon of Jupiter] in 2023 [and] 2024 exposed it to a lot of radiation," University of Kent space professor Mark Burchell told New Scientist. "So it is no surprise it is now showing anomalies in performance that need rebooting." "Could it be re-tasked?" he added. "In theory, if it can be done, and the instruments work, then there is novel data there." Unsurprisingly, intercepting an interstellar visitor that's screaming through outer space at 37 miles per second would be no easy feat even with brand new hardware. Any mission would need a lot of fuel and time to get anywhere near it. According to a yet-to-be-peer-reviewed paper by a team from Michigan State University, a new mission would need to accelerate at 15 miles per second on the day of discovery — which was July 1, so the clock is ticking — to get there in time. However, "spacecraft at Mars could be used to make valuable observations" around late November, when 3I/ATLAS hits its perihelion, or when it makes its closest approach to the Sun. "The perihelion of 3I/ATLAS will not be easily observable from Earth-based observatories, as the object will be on the opposite side of the Sun and at a low solar elongation angle," the paper reads. "However, the object will approach within 0.19 au [or 17.6 million miles] of Mars, and we encourage nearby spacecraft equipped with visible, UV, and IR spectrographs and cameras to attempt to capture data on this object's closest approach." The European Space Agency's Jupiter Icy Moons Explorer (JUICE) may also be able to get a look. The agency's Luca Conversi told New Scientist that "we are aware of this precious opportunity and are currently exploring the technical feasibility." "I'm not sure it is feasible to send it to the comet: unfortunately astro-dynamics is more complicated than what we see in sci-fi movies," he added, "and it is not easy to change the course of spacecraft." Time is quickly running out, and visiting 3I/ATLAS is starting to look like a Herculean task. But to scientists, it's an endeavor worth exploring nonetheless. "The closest approach to Earth will be in December," said coauthor and fourth-year Michigan State undergraduate Atsuhiro Yaginuma in a press release last month. "It would require a lot of fuel and a lot of rapid mobilization from people here on Earth." "But getting close to an interstellar object could be a once-in-a-lifetime opportunity," he added.

Crew-10 splashes down in Pacific after return from ISS
Aug. 9 (UPI) -- The four members of Crew-10 made a successful water landing off the coast of California Saturday morning, with splashdown taking place as scheduled shortly after 11:30 a.m. EDT. NASA astronauts Anne McClain and Nichole Ayers, Japan Aerospace Exploration Agency astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov are set to touchdown at the space agency's primary targeted site off the coast of San Diego. The crew successfully undocked from the International Space Station Friday evening, with confirmation coming at 6:30 p.m. EDT. Crew-10 was originally scheduled to depart the orbiting laboratory on Thursday, but that was postponed due to unfavorable weather at the landing site. The astronauts had been conducting research and science experiments during their five-month stay aboard the ISS. NASA livestreamed the flight aboard the fully-autonomous rocket during the 250-mile journey. The Falcon 9 rocket successfully separated from the Dragon spacecraft shortly before 11 a.m. EDT last Saturday. The splashdown in the Pacific Ocean off the coast of Southern California marks the first time one of NASA's Commercial Crew Program flights lands anywhere other than Florida. Once recovery is complete, the crew will be flown to Houston, Texas. Crew-10 launched from the Kennedy Space Center on March 14, using a similar Falcon 9 rocket produced by SpaceX. The four-member crew arrived at the ISS two days later, relieving astronauts aboard the ISS, including two that had been stranded after arriving on Boeing's Starliner spacecraft.
