Hubble Space Telescope Is 35: Don't Miss These 4 Dazzling Anniversary Images
The celebratory views include Mars, two nebulas and a galaxy. The variety of targets shows off Hubble's versatility and ability to see not only into deep space, but also into our own solar system.
NASA dropped a host of superlatives with words like "transformative," "evocative," "engaging" and "accessible" in its anniversary release statement. It's all true. Hubble's discoveries have been covered in over 22,000 papers, but its influence reaches far beyond science journals. It has shaped the public's view of our universe through groundbreaking images like the Pillars of Creation and the Hubble Deep Field.
Check out the anniversary images.
Earth may be humanity's favorite planet, but Mars is a close second. Hubble turned its gaze on the red planet at the end of 2024. The crisp views highlight the planet's northern polar cap at the beginning of the Martian spring. Gauzy clouds make Mars look like a frosty marble.
A white dwarf star lingers at the center of planetary nebula NGC 2899. This is one of the cosmic objects you can let your imagination run wild with. It resembles a misshapen butterfly or a moth in flight. ESA suggested the pinched middle looks like a half-eaten doughnut.
Gas and dust give the nebula its unique look. All this beauty traces to the tumultuous death of its central star.
Hubble's look at the Rosette Nebula focuses on a small part of a much larger formation.
The nebula is a place of active star formation. "Dark clouds of hydrogen gas laced with dust are silhouetted across the image," ESA said. "The clouds are being eroded and shaped by the seething radiation from the cluster of larger stars in the center of the nebula."
NGC 5335 is a barred spiral galaxy like our Milky Way. Hubble's image shows the distinctive bar across the middle of NGC 5335. "The bar channels gas inwards toward the galactic center, fueling star formation," said ESA. "Such bars are dynamic in galaxies and may come and go over two-billion-year intervals."
Hubble orbits Earth. Space is a tough place to live. The telescope's designers planned to get 15 years of use out of it, but Hubble handily outlasted that goal.
Hubble's longevity hasn't been easy. The telescope has weathered an array of technical problems over the years. NASA dispatched five space shuttle servicing missions to Hubble, with the last in 2009.
There are no more space shuttles in operation, so the Hubble team handles all fixes from afar. That has meant some big changes to Hubble's operations, particularly with the gyroscopes that help point it in the right direction. The Hubble team has had to get creative, but they've kept the aging observatory up and running and delivering fresh science and imagery.
Every Hubble anniversary feels like a triumph for the elderly space telescope. It may have a few more anniversaries left in it. NASA hopes it will continue operations into the 2030s. Long live Hubble.

Investing in Space: NASA's months of reckoning
For half a year now, NASA's been weathering a storm on every front, from its budget to its chain of command and potential program terminations. Employee uproar was an inevitable chapter of the saga. A group of 360 current and former NASA employees have penned a letter rebuking "rapid and wasteful changes" across staffing, mission and budgetary cuts at the space agency. "The last six months have seen rapid and wasteful changes which have undermined our mission and caused catastrophic impacts on NASA's workforce," the letter says, noting concerns that the proposed downsizing in personnel and funding are "arbitrary and have been enacted in defiance of congressional appropriations law" and that "the consequences for the agency and the country alike are dire." Signatories of the letter, titled the Voyager Declaration, urge the U.S. leadership not to implement "harmful" cuts and dispute "non-strategic staffing reductions," curtailing research projects, as well as cancelling contracts and participation in international missions or assignments for which Congress has already appropriated funding. It's no small list of objections raised at a time of broader uncertainty at NASA, which faces significant — and long chronicled — declines in funding and staff, amid a broader White House push to shrink down the federal workforce. "NASA will never compromise on safety. Any reductions—including our current voluntary reduction—will be designed to protect safety-critical roles," NASA Spokesperson Bethany Stevens said in an emailed statement. "The reality is that President Trump has proposed billions of dollars for NASA science, demonstrating an ongoing commitment to communicating our scientific achievements. To ensure NASA delivers for the American people, we are continually evaluating mission lifecycles, not on sustaining outdated or lower-priority missions." Adding to the tumult, NASA on Monday announced the high-level exit of Makenzie Lystrup, who will end her two-year stint as Goddard Space Flight Center director on Aug. 1. NASA says the step was communicated internally before any knowledge of the letter. It's not the first loss from the agency's senior ranks in recent months: Laurie Leshin stepped down from the director post of NASA's Jet Propulsion Laboratory in June. And more exits could be forthcoming: at the start of the month, Politico reported that at least 2,145 senior-level employees could depart NASA, many serving in core mission sets. Throughout, NASA — notable for both its own achievements and its substantial contracts to the U.S. private space industry — has remained without long-term leadership, after U.S. President Donald Trump's initial pick, tech billionaire and Elon Musk ally Jared Isaacman, was unexpectedly removed from consideration back in May. Sean Duffy, Trump's transportation secretary, was appointed to hold up the fort as NASA's interim administrator just this month. Inevitably, there's money on the line. NASA clinched a budget of $24.875 billion last year — 8.5% under its initial request and 2% below the funding of 2023 — that was matched in 2025. Under the Trump administration, the agency battled the possibility of a roughly 25% budget trim in 2026, although the U.S. House of Appropriations subcommittee has pushed back on these cuts. If enacted, the Trump funding proposal of $18.8 billion would have been the smallest NASA budget since before the U.S.' first crewed Moon landing via the Apollo 11 mission, commemorated this week on July 20. In a Monday statement, Trump said his administration is "building on the legacy of Apollo 11" and endorsed NASA's initiatives focused on "returning Americans to the Moon —this time to stay — and putting the first boots on Mars." Colonizing the red planet has been a vocally stated objective of the U.S. president since his January return to office, echoing the ambitions of his then-ally Musk. The two have since parted ways through an explosive rift, but the dream to land U.S. astronauts on the Moon and Mars has gripped the nation, with a respective 67% and 65% of those surveyed in a CBS News/YouGov pollv now in favor.

Elon Musk to give an update on Starship status and future plans
SpaceX boss Elon Musk has promised to lay out his company's plans for the mighty Starship rocket in an upcoming event. In a post on X on Thursday night, he said the presentation will take place shortly before the rocket's 10th flight test, which is expected to take place next in the first half of next month. 'Shortly before the next flight, I will do a live technical update on Starship, going over progress to date and engineering/production/launch plans for the future,' Musk said in the post. Recommended Videos The presentation, which is likely to take place at SpaceX's Starbase facility in Boca Chica, Texas, should offer some details on what his team has learned from recent flight tests and how it's used that knowledge to improve the rocket, which, packing some 17 million pounds of thrust at launch, makes it the most powerful launch vehicle ever. Recent Starship flights have been a mixed bag of impressive booster landings and lost spacecraft. There was also the spectacular explosion of the Starship spacecraft, which occurred shortly after a ground-based engine test in June. No one was hurt in the incident. Musk will also offer some information on how many Starship vehicles and boosters are currently being built, and possibly touch on any supply chain challenges. Many people will also be keen to hear about the launch plans for the Starship. Musk has spoken before about his desire to dramatically increase the launch frequency of the Starship so that SpaceX can work more quickly toward making it operational. NASA is planning to use the Starship to carry crew and cargo to the moon in highly anticipated missions before the end of this decade. It could also be used for the first crewed voyage to the surface of Mars. Musk had originally planned to hold the update event at around the time of the ninth flight test in late May, but it was called off at the last minute. The SpaceX chief has now confirmed it'll be happening in the coming weeks, and we'll know exact timings just as soon as SpaceX confirms the launch schedule for the 10th flight test.

Trump Megabill Tosses $1 Billion At Space Force's Boeing Spaceplane
It's difficult to believe that any legislator read all 940 pages of President Donald Trump's Big, Beautiful Bill before it was passed by Congress earlier this month. I wonder if the Senate was aware that the megabill allocated $1 billion to the U.S. Space Force's Boeing X-37B Orbit Test Vehicle. The American military's newest branch is proud to boast about how maneuverable the uncrewed spaceplane is in orbit. Still, little else is known about what the Boeing spacecraft is actually doing while looping the planet. The budget increase is certainly a statement of intent from the White House, especially when NASA's budget is slated to be slashed by $3.4 billion. The Boeing X-37B has been in service since 2010, back when the Space Force was Air Force Space Command. The spaceplane's familiar white and black thermal clad appearance is reminiscent of NASA's Space Shuttle, and it fulfills a similar role for the Pentagon, based on the publicly available information. Air Force Space Command didn't reveal the X-37B's payload for its first three flights. While the flights are still considered classified, the Space Force will reveal orbital deployment and experiments done in collaboration with other agencies. The seventh X-37B mission ended in March with the spaceflight landing at Vandenberg Space Force Base after 434 days in orbit. The mission conducted experiments with NASA to observe the effects of space radiation on plant seeds. Read more: You'd Only Drive These Cars If They Were Free Military Wants The Highest Ground Possible No, the X-37B's primary reason for spending over a year in orbit wasn't seeing if you could turn a packet of seeds into the Fantastic Four. The Space Force stated it tested the spaceplane's ability to complete maneuvers using atmospheric drag. The branch is gradually getting its feet wet in what space combat could look like with our spacefaring geopolitical rivals, like China and Russia. General Chance Saltzman, Chief of Space Operations, said: "Mission 7 broke new ground by showcasing the X-37B's ability to flexibly accomplish its test and experimentation objectives across orbital regimes. The successful execution of the aerobraking maneuver underscores the U.S. Space Force's commitment to pushing the bounds of novel space operations in a safe and responsible manner." Air Force Space Command's independence from the Air Force in 2019 wasn't just a Trump vanity project, but a push to militarize space. The $1 billion dedicated to the X-35B is part of a $11.3 billion budget increase for Space Force. This is happening amid the White House leaving civilian spaceflight on a shoestring budget and reliant on private companies. NASA's Artemis Program is still scheduled to return astronauts to the Moon, but is unclear how it'll get there. The Trump administration is trying to cancel the Space Launch System, but the agency won't halt the rocket's testing and development efforts. Want more like this?
