SpaceX launch could create sonic boom in Southern California, officials advise
The Falcon 9 launch of NASA's TRACERS mission, which will take place at Vandenberg Space Force Base's Space Launch Complex 4 East, is scheduled at 11:13 a.m. with an 57-minute long launch window.
"About eight minutes after liftoff, Falcon 9's first stage will land on SpaceX's Landing Zone 4 ... at Vandenberg Space Force Base, California," said a release from SpaceX. "There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the landing, but what residents experience will depend on weather and other conditions."
If necessary, a backup launch date is scheduled for Wednesday at the same time.
TRACERS, or Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, is a program that aims to "help understand magnetic reconnection and its effects in Earth's atmosphere," according to NASA's website. Scientists will evaluate how weather in space affects the weather on Earth.
In May, a sonic boom shook most of Southern California as SpaceX's Dragon spacecraft reentered Earth's atmosphere after a launch nearly a day earlier.

'Wild West of rocketry': Cape Canaveral's first launch, Bumper 8, marks 75th anniversary
It was "the wild, wild West of rocketry" back on July 24, 1950, when technicians inside a wooden tar-paper shack launched Cape Canaveral's first primitive rocket: Bumper 8, which had been assembled using a captured German V-2 missile. The experimental 56½-foot rocket's upper stage failed about 51,000 feet above the Atlantic Ocean waters. But Bumper 8 successfully accelerated America's Space Race and was "key to the DNA of the Cape," said Jamie Draper, director of the Cape Canaveral Space Force Museum. Seventy-five years and more than 8,000 missile and rocket launches later, Draper said Bumper 8 paved the way for the Cape to become America's premier gateway to space. "Bumper 8, when that launched, that was the early days of the Cold War. And you had the mad dash of missile development, paralleled with Space Race developments," Draper said. "What were they doing? They were testing all kinds of high-speed or high-velocity staging of rockets. That became essential for all of our future space programs, all the way up to today," he said. "And it all started with Bumper," he said. Bumper 8 rocket: Since 1st rocket launch 75 years ago, Brevard undergoes huge development sparked by Space Race A small group of scientists, engineers and technicians launched Bumper 8 at 9:28 a.m. that date from the Long Range Proving Ground, which would later become Cape Canaveral Space Force Station. This week, officials on Florida's Space Coast will host a pair of 75th anniversary events: ■ Thursday evening, the U.S. Space Force Historical Foundation will host an invitation-only celebration during a VIP dinner event at the Kennedy Space Center Visitor Complex. The speaker lineup features Space Force Maj. Gen. Stephen Purdy Jr. and former NASA administrator Jim Bridenstine, and the event will kick off the foundation's new Legacy of Launch fundraising drive. ■ For the general public, the newly remodeled and revamped Sands Space History Center — which celebrated a grand reopening in mid-June — will host a Bumper Bash from noon to 4 p.m. Saturday, July 26. Admission is free, and the museum address is 100 Spaceport Way on the north side of Port Canaveral. Activities will include scavenger hunts, giveaways, refreshments, special displays and a coloring station. Florida Historical Society Executive Director Ben Brotemarkle called Bumper 8 not only a landmark event in Space Coast history, but in national and world history. "I always have to smile looking at the photographs. It almost looks like an old science fiction movie — and the people seem to be right on top of the launch. You wonder about the safety protocols there. They seem to be right by where this rocket is going off," Brotemarkle said. 'The wild, wild West of rocketry' A control panel inside the Bumper blockhouse, shown in this July 1950 U.S. Air Force photo. Draper painted a portrait of how the Bumper 8 mission was "testing the waters on this newfangled thing called rocketry." After crews finished building the 100-by-100-foot concrete launch pad roughly ½-mile northeast of the Cape Canaveral Lighthouse, a cableway led to the technicians' unlikely "firing room" command center only 400 feet away: a wooden tar-paper shack. "Not a reinforced concrete bunker that they used for the next however-many decades. But that tar-paper shack, with that sandbag-and-sand berm surrounding it in a horseshoe pattern, offering some level of protection. That's the berm that all the photographers were on," Draper said. A telephone pole sunk into the pad's cement helped stabilize the rocket's umbilical tower, Draper said. And two "mobile service towers" standing six or seven stories tall were merely painters' scaffolding on wheels. "You look at these photos, and it's just all these shirtless servicemembers or contractors muscling the scaffolding in place, muscling this trailer around with the rocket on it to put it in position. Super rustic, compared to what followed just a couple years later," he said. During 2023-24, University of Central Florida Department of Anthropology students and faculty teamed up with Space Launch Delta 45 to excavate and study the long-abandoned Bumper 8 blockhouse site. The University of South Florida's Center for Digital Heritage and Geospatial Information also used a light scanner to create a 3D-map of the site. Now, the Sands Space History Center is displaying a Bumper 8 "First Cape Launch" feature exhibit through mid-August. Excavated blockhouse artifacts include pieces of tarpaper, roofing nails, fragments of mirror from a viewing periscope, grommets and pieces of a Coke bottle produced by a bottling plant in Cocoa. Rocketry fuels Space Coast's fast-paced growth In terms of economic and cultural impact, Brotemarkle said Bumper 8 — Cape Canaveral's inaugural launch — served as a catalyst for Brevard County's eye-popping population growth. Consider Cocoa Beach's statistics: A mere 246 people lived in sleepy Cocoa Beach in 1950, census records show. That population skyrocketed 14-fold during the 1950s as the Cold War heated up, reaching 3,475 residents by 1960. Then Cocoa Beach's population nearly tripled during the 1960s thanks to NASA's Project Mercury, Gemini and Apollo moon-race programs, hitting 9,952 residents by 1970. Two weeks ago, the Brevard County Commission adopted a resolution proclaiming Thursday as Space Coast Day in honor of Bumper 8's 75th anniversary. Draper said 16 Brevard communities and municipalities did likewise. The Space Coast Day proclamation noted that Bumper 8 and subsequent groundbreaking missions led to America's first satellite, Explorer I, orbiting Earth in 1958; Alan Shepard riding the first crewed Mercury capsule in 1961; John Glenn orbiting Earth in 1962; Apollo 11 landing on the moon in 1969; NASA's space shuttle program; and a permanent human presence in space aboard the International Space Station. "Bumper is just key to the DNA of the Cape. Not just for beginning this sequence of launches that's gone into 75 years, but for that spirit of exploration," Draper said. "It was just an epic, epic beginning to this premier gateway to space."

Blocks all stacked for NASA's future Artemis tower at KSC
There's still more than a year's worth of work to do on NASA's future Artemis launch tower at Kennedy Space Center, but all of the big pieces have been put in place. The last of seven modular steel blocks that make up the bulk of the tower's height was put into place on July 2 by the tower's contractor Bechtel. The block called Mod 10 brings it to 377 feet tall from the base structure. 'This achievement underscores our ongoing partnership with NASA and local unions, and the team's steady progress toward safe delivery of this critical infrastructure,' the company said in an emailed statement. Progress has been tracked on the company's website with the latest addition dubbed 'Reaching the Top.' Mod 4 was the first of the seven blocks put in place on Jan. 3, growing the structure 272 feet in less than six months. Mod 10 will support the Crew Access Arm for ML-2, which is among the parts that have yet to be assembled before the company's deadline of November 2026 for delivery to NASA. ML-2 is designed for use on a larger version of NASA's Space Launch System rocket, which won't fly until at least the Artemis IV mission on NASA's roadmap in late 2028. The first three Artemis missions have or will use the ML-1, which was converted from use from NASA's defunct Constellation program. Artemis I was the first launch of SLS, an uncrewed test flight that sent Orion out to the moon and back. Artemis II will be the first crewed flight of Orion, looking to send four astronauts on a trip around the moon without landing no later than April 2026. Artemis III looks to return humans to the moon for the first time since the end of the Apollo program in 1972. That mission, which is reliant on the completion of SpaceX's in-development Starship as a human landing system as well as new spacesuits from Axiom Space, is targeting launch by summer 2027. Whether or not ML-2 would ever be used was in question as President Donald Trump's proposed budget for fiscal year 2026 sought to end the SLS rocket program as well as the Orion spacecraft, Gateway lunar space station and NASA's Exploration Ground Systems team based at KSC after the flight of Artemis III. But Congress, led by an effort from Sen. Ted Cruz, was able add more than $10 billion in this year's 'Big, Beautiful Bill' to save SLS for both the fourth and fifth launches of Artemis as well as set aside money for Orion and Gateway. Both versions of the Senate and House budget bills for 2026, moreover, look to keep funding for Artemis' existing programs in place. Congress is the ultimate decider of what the federal budget will look like, although without an agreement, it's possible NASA will simply continue with funding based on current levels with continuing resolutions. Still, with funds already set aside, work continued in earnest to get ML-2 ready for the fourth Artemis flight. It's supposed to fly the first part of the Gateway station, and would use the larger version of SLS called the Block 1B that has more payload capacity. It too would feature a rendezvous and moon landing with Starship. The Artemis V mission is supposed to be the first flight to use Blue Origin's Blue Moon lander instead of Starship. NASA will still need to perform about a year's worth of tests and added work after Bechtel hands it off in 2026. The ML2 project, which was initially a $383 million contract awarded in 2019, had an original delivery date of 2023. A NASA Office of Inspector General audit released in August 2024 said the costs had already nearly tripled to more than $1 billion with the delivery date pushed into late 2026. It's part of the growing costs and delays associated with all facets of the Artemis program. In 2023, the OIG said by the time Artemis III flies, the program will have topped $93 billion in costs since it was originally announced in 2012. --------------

Is Earth's rotation speeding up? July 22 will be second shortest day in history
Earlier this month, the Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly shaved off the clock on July 9, but the shortest day out of all three predicted will be in August. This shortening is due to the moon's position relative to Earth and its influence on the planet's rotation. Here's what to know about why Earth's rotation is speeding up, and how it is shortening three days this summer. Is Earth's rotation speeding up? Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. If a standard day is shortened or lengthened by a number of milliseconds, that added or detracted time is referred to as "length of day," according to the website TimeAndDate. Until 2020, the shortest "length of day" ever recorded by atomic clocks was -1.05 ms, meaning that Earth completed one daily rotation in 1.05 milliseconds less than 86,400 seconds. "Since then, however, Earth has managed to shatter this old record every year by around half a millisecond," astrophysicist Graham Jones wrote for TimeAndDate. That culminated on July 5, 2023, with the shortest day of all time, with a "length of day" of -1.66 ms, according to Jones. While the variations are expected, recent research suggests that human activity is also contributing to Earth's changing rotation. Researchers at NASA calculated that dwindling ice and groundwater and rising seas have actually increased the length of our days since 2000 by 1.33 milliseconds per century . A photo of Earth rising over the moon's horizon taken in 1968 by astronaut Bill Anders How short will the day be on July 22 On July 22, scientists predicted a -1.38 ms "length of day." This is a little bit faster than July 9, , which had about a -1.30 ms "length of day," according to TimeAndDate. August 5 is expected to the most truncated at -1.51 ms "length of day." On these days, the moon will be at its furthest from the Earth's equator, changing its gravitational pull and causing our planet to spin just a tiny bit faster on its axis, according to science news website LiveScience. Will the sped-up day be noticeable? Of course, you're unlikely to notice such a minuscule difference in your standard 24-hour day. But scientists who track and operate atomic clocks may be facing a bit of a predicament. First introduced in the 1950s, atomic clocks replaced how scientists previously measured the length of a day by tracking the Earth's rotation and the position of the sun. The clocks are also capable of measuring in billionths of a second, or nanoseconds, which are synchronized globally to Coordinated Universal Time (UTC.) If the clocks are thrown off even a tiny amount, it could also throw off computers, servers, GPS signals, and other networks that rely on accurate times, David Gozzard, an experimental physicist at the University of Western Australia, told the Guardian.
