NASA satellite spies Curiosity chugging along on Mars
NASA's Mars Curiosity rover has traveled over 21.33 miles since it first landed on the Red Planet in 2012. That might not seem like very far, but it's an impressive trek considering the vehicle only averages about 98 feet per hour and mission engineers must remotely steer it from over 140 million miles away.
Curiosity's most recent journey began on February 2, when it started inching away from the Gediz Vallis channel towards a region with honeycomb-like boxwork formations potentially created billions of years ago by groundwater. On February 28—Curiosity's 4,466th Martian day—another NASA mission orbiting far overhead managed to snap what is believed to be the first image of the rover actively driving across the Red Planet.
Taken by the High-Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter, the black-and-white picture shows the desolate planetscape interrupted by a small, dark speck trailed by a weaving line of tire tracks. According to NASA, the path stretches back roughly 1,050 feet to chart Curiosity's estimated 11 drives while en route to the boxwork formations. Curiosity was preparing to ascend a steep slope at the time of the latest satellite photo, which NASA says it has since scaled.
'By comparing the time HiRISE took the image to the rover's commands for the day, we can see it was nearly done with a 69-foot drive,' said Doug Ellison, Curiosity's planning team chief at NASA's Jet Propulsion Laboratory (JPL) in California.
HiRISE is one of six observational instruments on the Mars Reconnaissance Orbiter that are used to document the planet's surface in high detail. The camera primarily produces black-and-white images with a colorized strip running down the middle to ensure optimal spatial resolution. It previously spotted Curiosity in color in 2023.
NASA's rover is making the most of the ground it's covering on Mars. Earlier this month, researchers announced that sediment samples collected by Curiosity and analyzed in its onboard mini-lab contained a key ingredient required for life to once exist on the planet. In March, another study confirmed the rover had detected the largest-ever organic molecules inside what is likely a dried lakebed.
Curiosity's mission team expects it to reach its next intended destination within the next month, depending on conditions on Mars. Once it arrives, Curiosity's most recent tracks will remain embedded in the terrain for a few months–until Martian winds erase them completely.

Stunning first images from powerful space telescope show new 'peek of cosmos'
Stunning images showing distant parts of the universe - including one of a region situated thousands of light years from Earth - have been captured by a powerful new telescope. The camera at the Vera C Rubin Observatory in Chile is expected to reveal new details from space on an unprecedented scale as it makes further observations during the next decade. Scientists expect it to chart thousands of asteroids not previously identified - and believe it will discover within months whether there is a ninth planet in our . The new images show the light from millions of stars and galaxies in observations which took the world's largest and most powerful camera only 10 hours to complete. One image shows a mosaic of the Trifid and Lagoon nebulae, a star-forming region which is 9,000 light years from Earth. A single light year is the distance light travels in 12 months. In space, it "zips through at 186,000 miles per second and 5.88 trillion miles per year", says NASA. Another image shows thousands of galaxies in the Virgo Cluster, in what scientists said offers just a "peek at the cosmos". The observatory is jointly funded by the National Science Foundation, an independent agency of the US government. The foundation's chief of staff Brian Stone told CNN the observatory "will capture more information about our universe than all optical telescopes throughout history combined". Rubin has been built on a mountain in the Andes, a region in central Chile which is also home to other observatories due to its dry air and dark skies. The telescope's work will "capture the cosmos in exquisite detail" as it repeatedly scans the sky for 10 years to "create an ultra-wide, ultra-high-definition time-lapse record of our universe". Read more from Sky News: Scientists in the UK will be working in partnership with the teams at Rubin to help process the detailed information and images captured by the telescope. The National Science Foundation is expected to release more images and video from Rubin's initial work later on Monday.

Thousands of asteroids and millions of galaxies shine in first images from the largest camera ever built
The first test images from a groundbreaking observatory named for trailblazing astronomer Vera Rubin have captured the light from millions of distant stars and galaxies on an unprecedented scale — and are expected to reveal thousands of previously unseen asteroids. While the National Science Foundation has so far released only a couple of images and a brief video clip of the Vera C. Rubin Observatory's first imagery, more images and videos taken using the largest camera ever built are expected to be shared at 11:30 a.m. ET Monday on the agency's YouTube channel. The facility is jointly funded by the National Science Foundation and the Department of Energy's Office of Science. The new images represent just over 10 hours of test observations, offering a brief preview of the observatory's decade-long mission to explore the mysteries of the universe like never before. 'NSF-DOE Rubin Observatory will capture more information about our universe than all optical telescopes throughout history combined,' said National Science Foundation Chief of Staff Brian Stone, who is currently performing the duties of the NSF director (as the position is currently vacant). Among the observatory's initial accomplishments was the discovery of 2,104 asteroids, including seven near-Earth asteroids, that have never been seen before in our solar system. None of the newly found near-Earth asteroids pose a risk to our planet, according to scientists at the observatory. Imagery of the asteroids is expected to be shared later Monday. While ground- and space-based telescopes spot about 20,000 asteroids each year, Rubin Observatory is expected to uncover millions of the space rocks within its first two years, according to the National Science Foundation. The telescope is also considered the most effective way to spot any interstellar comets or asteroids that may travel through our solar system. The observatory's mirror design, sensitive camera and telescope speed are all the first of its kind, enabling Rubin to spot tiny, faint objects such as asteroids. The observatory will also constantly take thousands of images every night, cataloging changes in brightness to reveal otherwise hidden space rocks like near-Earth asteroids that could be on a collision course with our planet, according to the foundation. A sneak peek shared Monday includes a video made from over 1,100 images captured by the observatory that begins with a detailed look at two galaxies. The video then zooms out to showcase about 10 million galaxies spotted by the camera's wide view — roughly 0.05% of the 20 billion galaxies Rubin will observe over 10 years. The observatory team also released a mosaic of the Trifid and Lagoon nebulae, which are star-forming regions that resemble clouds located in the Sagittarius constellation. The mosaic, made up of 678 separate images taken over just seven hours, captured faint and previously invisible details such as clouds of gas and dust in the nebulae, which are several thousand light-years away from Earth. The initial images were selected to showcase the telescope's enormous field of view, which enables detailed glimpses of interacting galaxies as well as broad views of millions of galaxies, said Dr. Yusra AlSayyad, deputy associate director of the data management subsystem for the Rubin Observatory. 'It has such a wide field of view and such a rapid cadence that you do have that movielike aspect to the night sky,' said Dr. Sandrine Thomas, telescope project scientist for the Rubin Observatory. The observatory, located in the Andes on the top of Cerro Pachón in Chile, is nearly complete after about two decades of work. The facility is set to achieve 'first light,' or make the first scientific observations of the Southern Hemisphere's sky using its 8.4-meter (27.5-foot) Simonyi Survey Telescope, on July 4. The telescope's location in the Southern Hemisphere allows for a great view of the Milky Way's galactic center, said Edward Ajhar, Rubin Observatory's program officer. The region in central Chile has also been home to other ground-based observatories and is favored for astronomical observations because it affords dry air and dark skies. The observatory's main objective is the Legacy Survey of Space and Time, an ultrawide and ultra-high-definition movie of the universe made by scanning the entire sky every few nights over 10 years to capture a time-lapse compilation of whizzing asteroids and comets, exploding stars, and distant galaxies as they change. The survey is expected to begin between four to seven months after first light. '(Rubin) will enable us to explore galaxies, stars in the Milky Way, objects in the solar system, and all in a truly new way. Since we take images of the night sky so quickly and so often, (it) will detect millions of changing objects literally every night,' said Dr. Aaron Roodman, professor of particle physics and astrophysics at Stanford University's SLAC National Accelerator Laboratory in California. Roodman was responsible for the assembly and testing of Rubin Observatory's camera. Rubin's capabilities to spot interesting phenomena will also enable it to be a 'discovery machine' that can identify interesting areas of focus for other telescopes, Roodman said. The observatory could also enable the detection of previously unknown types of celestial objects. The telescope's namesake, considered to be one of the most influential women astronomers, provided some of the first evidence that dark matter existed. In Rubin's honor, the telescope is expected to continue her pioneering work. 'Through this remarkable scientific facility, we will explore many cosmic mysteries, including the dark matter and dark energy that permeate the universe,' Stone said. Dark matter is an enigmatic substance that shapes the cosmos, while dark energy is a force that accelerates the expansion rate of the universe, according to NASA. Though they are thought to make up most of the cosmos, both are impossible to directly observe but can be detected due to their gravitational effects. 'Rubin has enormous potential to help us learn what dark energy really is and how the universe's expansion is accelerating here, too,' Roodman said. 'Rubin's unique ability to see billions of galaxies and to image them repeatedly over 10 years will literally enable us to see the universe in a new way.'
