Asteroids still pose a danger to our planet. Earth scientists are actively working on this problem
NASA’s new NEO Surveyor spacecraft will search for the hardest-to-find asteroids and comets that could pose a threat to our planet, making it the agency’s first space telescope designed specifically for planetary defense. The impact craters that scar the Earth’s surface are evidence of the enormous impact asteroids have had on the history and development of our planet.
Hera mission to visit previously shot down asteroid Dimorphos to assess impact of its DART collision
Dimorphos is a moon of the near-Earth asteroid Didymos. This binary asteroid system was previously visited by NASA’s DART spacecraft, which deliberately collided with Dimorphos in 2022 and changed its orbit around Didymos as a demonstration of a planetary defense technique designed to change the trajectory of a potentially hazardous asteroid.
Earth temporarily has a new ‘mini-Moon’
On Sunday, September 29, Earth captured a new “mini-moon” called 2024 PT5. The bus-sized asteroid is expected to orbit our planet for 57 days, but it’s too small to be seen by amateur skywatchers. This isn’t the first time such a phenomenon has occurred. In 2020, astronomers identified another mini-moon, 2020 CD3, which orbited Earth for more than a year.
The Draconid meteor shower will be visible tonight
The Draconids meteor shower will reach its peak activity today, on the night of Wednesday, October 9. The number of “shooting stars” at this time can reach 15 per hour. The peak of the meteor shower is expected at approximately 16:00 Moscow time, but shooting stars can also be observed after dusk, the Moscow Planetarium reported.
Black Hole Systems: Gravitational Waves of Space-Time Learned to Catch on Earth
Astronomers have discovered supermassive black holes with masses millions or billions of times that of the Sun in most massive galaxies in the local Universe, including our own Milky Way. Webb’s new observations provide evidence of an ongoing merger of two galaxies and their massive black holes when the Universe was just 740 million years old. The system is known as ZS7. Most black hole binaries are expected to be in what are called “quasi-circular” orbits. The giant black holes are thought to have been created when two smaller black holes collided and merged one day. And now scientists are wondering if we can learn about the black hole family tree by working backwards through the generations.
China outpaces rivals in space exploration
China built its own Tiangong space station, also known as “Tianhe”, located at altitudes of 217 and 280 miles (340 to 450 kilometers) in low Earth orbit in 2021. For the first time in more than four decades, it was China that brought moon rocks to humanity. China launched the Chang’e-6 probe to return soil from the far side of the Moon. The Chinese Academy of Sciences (CAS) Einstein Probe spacecraft was launched on January 9, 2024. China has already begun to lead the world in military launches, sending 45 defense satellites into orbit in 2022.
Modern latest satellite meteorological monitoring systems
Space-based observing systems account for approximately 90% of the data used in global numerical weather prediction models. Everyone on Earth is affected by the effects of climate change, such as rising temperatures, changing precipitation patterns and rising sea levels. Natural disasters such as volcanic eruptions, floods and tornadoes can dramatically change the Earth’s surface to the point where the changes are visible in space. Changes caused by human actions and interventions such as mining and deforestation are also visible in satellite images. Collecting climate data helps communities better plan for and become more resilient to these changes.
Space debris threatens not only the further exploration of outer space, but also directly the inhabitants of the Earth
NASA confirms that the object that crashed into a house in Florida was indeed space debris from the ISS. Satellites are burning up in the upper atmosphere – and we still don’t know what impact this will have on the Earth’s climate. Space pollution threatens the Earth’s magnetosphere; the deposition of highly conductive materials can reduce the planet’s protective capabilities, an expert says.
Astronauts on the ISS are looking for solutions to problems that may arise during a long flight
The flight of Russian cosmonauts and NASA astronauts, participants of the 70th long-term expedition, continues at the International Space Station. A long stay in space causes physical changes in the human body. For example, the condition of bones and muscles deteriorates. Therefore, the health of astronauts is closely studied by doctors and scientists.

Groundwater reserves are catastrophically declining
Groundwater supplies are being depleted in aquifers around the world, a new study has found, with the rate of decline accelerating over the past four decades in nearly a third of the aquifers studied. Rapid declines in water levels are most common in aquifers beneath cropland in drier regions, the largest analysis of groundwater trends shows.
75% of the world’s industrial fishing vessels are not trackable
An innovative study by Sentinel-1 and AI (European Space Agency) combining satellite data and artificial intelligence has shed light on the number of ships, wind turbines and oil platforms at sea. Shockingly, the study shows that about 75% of the world’s industrial fishing vessels were previously hidden from publicly available tracking systems. The study, published recently in the journal Nature, was conducted by Global Fishing Watch, an organization that seeks to improve ocean governance through increased transparency of human activity at sea.
Eighth asteroid discovered before it collides with Earth
On January 20, 2024, astronomer Christian Sarnecki discovered an asteroid approaching Earth, which just hours later crashed into our planet’s atmosphere 50 km west of Berlin, creating a fireball. Dubbed “2024 BX1”, it is only the eighth asteroid discovered by humanity before the impact, and the third discovered by Sarnetsky. The asteroid impact created a bright fireball, or bolide, that was visible from as far away as the Czech Republic and may have scattered small meteorites across the ground at the impact site about 37 miles (60 kilometers) west of Berlin.
The Arctic, Antarctica and Greenland have received special attention from organizations involved in space research

The US-India satellite NISAR will begin monitoring changes in the Earth’s frozen regions in 2024.
The European Space Agency has announced a space economy in collaboration with international partners
From managing climate change to emergency response and digitizing the economy, space exploration is becoming increasingly important to life on Earth. To help policymakers and businesses make informed decisions about investments in space, ESA (European Space Agency) has published plans to create robust and reliable data on the space economy in collaboration with international partners.
The scientific community is studying the Apophis asteroid approaching Earth
Scientists estimate that asteroids the size of Apophis, about 367 yards across, come this close to Earth only once every 7,500 years. Asteroid Apophis will make an exceptionally close approach to our planet on April 13, 2029. Although Apophis will not collide with Earth during this approach or in the foreseeable future, its passage in 2029 will be within 32,000 kilometers of Earth. At this point, it will be closer than some satellites and can be seen with the naked eye in Earth’s eastern hemisphere. Although the encounter with Apophis is more than five years away, the next milestone on its path will be the first of six close transits of the Sun.

The main goal of NASA’s mission, called DART (Double Asteroid Redirection Test), is to test the ability to change the trajectory of an asteroid as it orbits its larger companion asteroid.
