The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

Spectrometer based on LEGO constructor will make studying physics cheaper

German physics teachers made a universal spectrometer in the Czerny-Turner scheme using LEGO constructors and scrap materials. The authors showed that it can be used to study the spectra of atomic emission, transmission, reflection and fluorescence. Reconfiguring the device for different tasks takes a few minutes, and the total cost of the device does not… Continue reading Spectrometer based on LEGO constructor will make studying physics cheaper

Perseverance discovered volcanic rocks instead of sedimentary ones in Jezero Crater

The Perseverance rover discovered volcanic rocks in the Jezero Crater. This contradicts the expectations of scientists who expected to see sedimentary deposits. Their absence may indicate that the lake at this place disappeared too quickly, and sedimentary rocks did not have time to form. Two articles (1 and 2) devoted to the results of Perseverance‚Äôs… Continue reading Perseverance discovered volcanic rocks instead of sedimentary ones in Jezero Crater

Physicists saw Rabi oscillations using extreme ultraviolet light

European physicists have reported the observation of characteristic doublets in the spectra of electrons knocked out of helium atoms by coherent light in the extreme ultraviolet range. The result obtained indicates the occurrence of Rabi oscillations in atoms. The shape and position of the doublets could be theoretically reproduced only after taking into account the… Continue reading Physicists saw Rabi oscillations using extreme ultraviolet light

One of the Trojans for the Lucy station turned out to be an asteroid with a satellite

Astronomers have summed up their observations of the occultation of the background star by the Trojan asteroid Jupiter Polymela, which was chosen as one of the targets for the interplanetary station Lucy. Their results confirmed the discovery of a satellite with a diameter of 5 kilometers around the asteroid, which is located at a distance… Continue reading One of the Trojans for the Lucy station turned out to be an asteroid with a satellite

A third of zinc fell to Earth with meteorites

Carbonaceous chondrites could deliver up to a third of the total amount of zinc to Earth, although their contribution to the total amount of substances on Earth is no more than six percent. They could also be a source of other elements besides zinc – mercury, selenium, noble gases. Article published in Icarus. The gradual… Continue reading A third of zinc fell to Earth with meteorites

South Korea's first lunar probe, Danuri, launched aboard Falcon 9

The Falcon 9 launch vehicle carrying the Danuri lunar probe, South Korea's first interplanetary spacecraft, launched from Cape Canaveral. The probe will operate in a lunar polar orbit for at least a year, studying the composition and structure of the Moon's surface, and will also look for ice deposits in the Moon's polar craters. The… Continue reading South Korea's first lunar probe, Danuri, launched aboard Falcon 9

The Arab station Al Amal showed the ultraviolet glow of the Martian atmosphere

The Al Amal Mars station team presented an animation of the dynamics of the ultraviolet glow of the Martian atmosphere, covering one Earth year. An increase in the brightness of the glow occurs due to increased activity of the Sun and a reduction in the distance between it and Mars, reported on the mission's Twitter… Continue reading The Arab station Al Amal showed the ultraviolet glow of the Martian atmosphere

Planetologists have found an explosive eruption of acidic magma in the ancient history of Mars

Scientists have simulated the formation of a mineral complex found by the Curiosity rover in the rocks of Gale Crater and including the rare mineral tridymite. It turned out that their joint occurrence was best satisfied by the conditions of an explosive volcanic eruption, which was fed by acidic magma, followed by the deposition of… Continue reading Planetologists have found an explosive eruption of acidic magma in the ancient history of Mars

NASA postpones the launch of the VIPER rover for a year

NASA has postponed the launch of the VIPER rover to the south pole of the Moon from November 2023 to November 2024. The delay is due to the need for additional testing of the Griffin lunar module, which is being developed by the private company Astrobotic Technology, according to NASA's website. VIPER (Volatiles Investigating Polar… Continue reading NASA postpones the launch of the VIPER rover for a year
