China on Wednesday embarked on its first mission to retrieve samples from a nearby asteroid with the nighttime launch of its Tianwen-2 spacecraft, a robotic probe that could make the fast-growing space power the third nation to fetch pristine asteroid rocks.China's Long March 3B rocket lifted off around 1:31 a.m. local time from the Xichang Satellite Launch Center carrying the Tianwen-2 spacecraft, which over the next year will approach the small near-Earth asteroid named 469219 Kamoʻoalewa, some 10 million miles away.Chinese state media Xinhua confirmed the launch of Tianwen-2 and dubbed it a "complete success."Tianwen-2 is scheduled to arrive at the asteroid in July 2026 and shoot a capsule packed with rocks back to Earth for a landing in November 2027.The mission is the latest example of China's swiftly expanding space programs, a streak of cosmic achievements in recent years that includes landing robots on the far side of the moon, running its own national space station in orbit and investing heavily in plans to send humans to the lunar surface by 2030.Japan's Hayabusa that fetched samples from a small asteroid in 2010 marked the world's first such mission. Japan did it again in 2019 with its Ryugu mission, followed by the first U.S. asteroid retrieval mission, OSIRIS-REx, that brought back samples from the Bennu asteroid in 2020.Kamoʻoalewa, the target asteroid for Tianwen-2, is known as a quasi-satellite of Earth, a close celestial neighbor that has orbited the sun for roughly a century, according to NASA. Its size is anywhere between 120 feet (40 meters) and 300 feet (100 meters).

Elon Musk has a SpaceX ‘challenge' for NASA's entire budget for 2026
Elon Musk has issued a financial "challenge" to NASA, stating that SpaceX 's commercial revenue will exceed the entire budget of the government space agency in 2026. The tech billionaire, who is also the CEO of SpaceX, took to the social media platform X (earlier Twitter) to predict that the rocket maker is projected to record nearly $15.5 billion in revenue this year. This figure highlights SpaceX's increasing presence in the commercial space sector . In his X post, Musk specifically noted that SpaceX's commercial revenue from space operations in 2026 will surpass NASA 's projected budget of roughly $1.1 billion for that same year. In the X post, Musk wrote: 'Perhaps an interesting milestone: @SpaceX commercial revenue from space will exceed the entire budget of @NASA next revenue this year will be ~$15.5B, of which NASA is ~$1.1B.' How Elon Musk's SpaceX may be able to achieve this feat by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo According to a report by the news agency Reuters, while NASA continues to fund deep space exploration and scientific missions, SpaceX seems to have capitalised on rising demand for affordable launch services and satellite-based communications to drive revenue growth. SpaceX is also developing its 400-foot (122-meter) Starship rocket, which Elon Musk has said will be vital in enabling future human missions to Mars. SpaceX's reusable Falcon 9 and Falcon Heavy rockets have significantly lowered launch costs, helping the company capture a dominant share of the global launch market. In 2024, SpaceX completed 134 Falcon launches — a record-breaking achievement that made it the most active launch operator worldwide. As per the Reuters report, the company aims to surpass this milestone with 170 launches by year-end to keep up with increasing satellite deployment demand. The report also notes that much of SpaceX's revenue stems from its Starlink satellite internet service. Musk has said Starlink will go public, though no timeline has been confirmed. In November 2023, Musk announced that Starlink had reached breakeven cash flow. Thousands of Starlink satellites have already been deployed to provide global broadband coverage. Additionally, as per Reuters, SpaceX and two other partners have become leading contenders to secure a key role in the US 'Golden Dome' missile defence initiative, a project backed by President Donald Trump.

James Webb Telescope clicks pictures of a galaxy with 800 billion Suns
James Webb Telescope clicks picture of a galaxy with 800 billion Suns 04 Jun, 2025 Credit: Nasa NASA's Webb Telescope captured a near-infrared image of the Sombrero galaxy, highlighting its bright central bulge while revealing less of the dust disk due to infrared light's ability to pass through dust. Observing the galaxy in visible (Hubble), near-IR, and mid-IR (Webb) helps astronomers study how stars, dust, and gas interact and evolve over time. The mid-infrared image shows the galaxy's dust glowing, while in near-infrared, stars shine through more clearly, making the dust less pronounced. Located 30 million light-years away, the Sombrero galaxy is seen nearly edge-on and has a mass equivalent to about 800 billion Suns. Variations in the chemical makeup of its 2,000+ globular clusters suggest the galaxy may have merged with another galaxy in the past. A noticeable warp in the inner disk, visible due to our slightly tilted viewing angle, supports the idea of a past galactic merger. Webb's powerful resolution reveals red giant stars and a colorful array of distant background galaxies, offering more clues about stellar evolution and cosmic structure.

UPSC Essentials brings to you its initiative of subject-wise quizzes. These quizzes are designed to help you revise some of the most important topics from the static part of the syllabus. Attempt today's subject quiz on Science and Technology to check your progress. 🚨 Click Here to read the UPSC Essentials magazine for May 2025. Share your views and suggestions in the comment box or at With reference to the Quasars, consider the following statements: 1. They are the extremely active and bright cores of some distant galaxies. 2. Quasars are powered by a supermassive black hole. 3. All quasars are not active galactic nucleus (AGNs), but all AGNs are quasars. How many of the statements given above are correct? (a) Only one (b) Only two (c) All three (d) None Explanation — The European Southern Observatory has announced the discovery of an incredibly brilliant quasar, which is not only the brightest of its type but also the most luminous object ever observed in space. — Quasars are the extraordinarily active and brilliant nuclei of some distant galaxies, fuelled by supermassive black holes. Supermassive black holes evolve by consuming materials drawn in by their extremely intense gravity. Hence, statements 1 and 2 are correct. — A quasar is a very active and bright form of active galactic nucleus (AGN). While all quasars are AGNs, not all AGNs are quasars. Hence, statement 3 is not correct. — Quasars are a subclass of active galactic nuclei (AGNs), which are exceptionally bright galactic centres where gas and dust collide with a supermassive black hole to generate electromagnetic radiation across the whole electromagnetic spectrum. Therefore, option (b) is the correct answer. The impact of solar flares can be seen over: 1. Radio communications 2. Electric power grids 3. Navigation signals Select the correct answer using the codes given below: (a) 1 and 2 only (b) 2 only (c) 2 and 3 only (d) 1, 2 and 3 Explanation — A solar flare is a massive explosion on the Sun caused by the rapid release of energy trapped in 'twisted' magnetic fields (often found above sunspots). — In just a few minutes, they heat material to millions of degrees and emit a blast of radiation across the electromagnetic spectrum, from radio waves to X-rays and gamma rays. — Solar flares are tremendous bursts of energy that can disrupt radio communications, power grids, navigation signals, and even endanger humans in space, satellites, and spacecraft. Therefore, option (d) is the correct answer. Near-Infrared Spectrometer and Photometer (NISP) and Visible Imager (VIS) are the payloads of: (a) Euclid space telescope (b) Chandrayaan 3 (c) Hubble Space Telescope (d) James Webb Space Telescope Explanation — Astronomers at the European Space Agency (ESA) have hit the jackpot after their telescope, Euclid, obtained high-resolution photos of 26 million galaxies, revealing a vast treasure trove for researching the dark cosmos. — The Euclid Mission is led by ESA, with assistance from scientists from NASA, Japan, and Canada. Euclid is a 1.2-metre telescope designed to map massive spatial structures in our universe, such as galaxies, in order to help reconstruct how the universe expanded and how galaxy formations evolved to look the way they do now. It carries two scientific payloads: a near-infrared spectrometer and photometer (NISP) and a visible imager. Therefore, option (a) is the correct answer. Malapert is a: (a) Deep craters near Mercury's poles (b) Impact crater on Mars (c) Shield volcano on Mars (d) A crater in the South Pole region of the Moon Explanation — Texas-based Intuitive Machines' Odysseus lander attempted to become the first privately-led mission to soft-land on the Moon. The lunar lander will attempt to land near Malapert (A crater in the South Pole region of the Moon), not far from ISRO's Chandrayaan-3 lander. Therefore, option (d) is the correct answer. Which of the following nuclear power plants has developed the country's first Indigenous Fast Breeder Reactor (FBR)? (a) Kalpakkam Atomic Power Plant (b) Kudankulam Atomic Power Plant (c) Rawatbhata Atomic Power Plant (d) Tarapur Atomic Power Plant Explanation — The crucial second stage of India's three-stage nuclear programme received a boost with the start of 'core loading' at the country's first indigenous Fast Breeder Reactor (FBR) at Kalpakkam, Tamil Nadu. — Core loading is the process of inserting nuclear fuel assemblies into the core of a nuclear reactor. — The completion of core loading will effectively signal the first step towards 'criticality' — the start of a self-sustaining nuclear fission reaction that will eventually lead to power generation by the 500 megawatt electric (MWe) FBR. — India will become the second country, after Russia, to have a commercial working FBR. China has a minor rapid breeder program, but programs in Japan, France, and the United States have been halted because of safety concerns. Therefore, option (a) is the correct answer. Consider the following areas related to Science and Technology: 1. Astrophysics 2. Nanoscience 3. Neuroscience In which of the above mentioned fields are 'The Kavli Prizes' awarded? (a) 1 only (b) 1 and 2 only (c) 3 only (d) 1, 2 and 3 Explanation — The Kavli Prize is awarded in honour of Norwegian-American businessman and philanthropist Fred Kavli (1927-2013). — 'The Kavli Prizes are awarded in three areas: astrophysics, nanoscience and neuroscience — the largest, the smallest, and the most complex. I believe these prizes are in the most exciting fields for the twenty-first century and beyond,' Kavli said, while describing the prizes. Therefore, option (d) is the correct answer. With reference to Heisenberg's Uncertainty Principle, consider the following statements: 1.
