Artemis II Rocket Boosters: NASA “Worm” Logo Added | Kennedy Space Center

Teams with NASA’s Exploration Ground Systems Program at the agency’s Kennedy Space Center in Florida completed painting the NASA “worm” logotype onto the booster motor segments that will form the Space Launch System (SLS) rocket’s twin solid rocket boosters for Artemis II, the first crewed mission of NASA’s Artemis campaign. Crews began painting the logo Jan. 22, 2024, and completed the painting and priming process Feb. 16, 2024. 

When fully stacked, the SLS boosters stand 17 stories tall and are the largest, most powerful solid propellant boosters ever flown, providing more than 75% of the thrust at liftoff. Spanning 25 feet end to end—or roughly the length of one booster motor segment—the red logotype will be clearly visible on either side of the mega rocket’s boosters during launch and flight.

The Moon's Schomberger Crater | Intuitive Machines' Odysseus Lunar Lander

The Moon's Schomberger Crater | Intuitive Machines' Odysseus Lunar Lander

On February 22, 2024, Intuitive Machines’ Odysseus lunar lander captured a wide field of view image of Schomberger Crater on the Moon "approximately 125 miles (200 km) uprange from its intended landing site, at approximately about 6 miles (10 km) altitude." Schomberger is a prominent lunar impact crater that lies in the southern part of the Moon, in the area near the limb. 

On Feb. 22, 2024, the IM-1 Mission Nova-C Moon Lander, named "Odysseus," became the first American spacecraft to land on the Moon’s surface since the NASA Apollo 17 moon landing in 1972. It appears that the lander is in a horizontal orientation instead of a vertical one and that communication with the lander remains an issue. Intuitive Machines hopes to provide post-landing pictures and an update on the spacecraft's operational capabilities and status over the next several days.

China's Chang'e 3 Mission, the first Chinese landing on the Moon in 2013, was the first spacecraft to soft-land on the Moon since the Soviet Union's Luna 24 in 1976.

In 2023, after the Chandrayaan-3 Lander successfully soft-landed on the Moon, India became the fourth country, after the United States, Russia and China, to accomplish this.

NASA’s Commercial Lunar Payload Services (CLPS) initiative allows NASA to send science investigations and technology demonstrations to the lunar surface. Under Artemis, NASA will study more of the Moon than ever before, and CLPS will demonstrate how NASA is working with commercial companies to achieve robotic lunar exploration.

China Names Its Crewed Moon Exploration Vehicles Mengzhou & Lanyue

China Names Its Crewed Moon Exploration Vehicles Mengzhou & Lanyue

The China Manned Space Engineering Office (CMSEO) on Feb. 24, 2024, unveiled the official names of the new vehicles for its future crewed lunar exploration missions. After an open solicitation and selection, the new-generation crewed spacecraft and the lunar lander for the missions were named Mengzhou and Lanyue, respectively.

According to an earlier report, China plans to land its astronauts on the moon before 2030. The plan is to launch two carrier rockets to send a lunar lander and a manned spacecraft, respectively, to a lunar orbit. The craft and the lunar lander will rendezvous and dock with each other, and then astronauts will enter the lander.

The names of the new vehicles were solicited from the public in an event launched last August, which drew enthusiastic participation from across the country. The two names chosen were selected from nearly 2,000 submissions.

"The names Mengzhou and Lanyue of the two new space vehicles carry distinct characteristics of China and the times, and have rich cultural connotations. The manned spacecraft Mengzhou and the lunar lander Lanyue, together with the Long March-10 carrier rocket, will carry forward Chinese people's dream of exploring the vast universe and reaching the moon," said Ji Qiming, director assistant of the CMSEO.

The new-generation spacecraft Mengzhou has two versions—one for lunar exploration and the other for carrying astronauts to China's space station.

China's Tiangong Space Station Holds Youth Art Exhibition

China's Tiangong Space Station Holds Youth Art Exhibition

An exhibition, featuring 53 pieces of art made by children, was launched at China's orbiting Tiangong Space Station on Friday, February 23, 2024. Under the theme of "Chinese modernization in the eyes of children," this is the third exhibition of its kind held on the Tiangong. The paintings were selected from more than 20,000 pieces of artwork by youngsters from across China since October last year.

The Shenzhou-17 crew, namely Tang Hongbo, Tang Shengjie and Jiang Xinlin, who arrived at the space station on Oct 26, 2023 for a six-month mission, displayed the paintings on two large silk scrolls.

The trio sent a message of encouragement to the youngsters across China, hoping that they will turn their best wishes for the motherland in the paintings into reality one day.

The 53 paintings, along with space supplies, were sent to the station by the Tianzhou-7, the latest cargo spacecraft launched by China on Jan 17.

The first Tiangong painting exhibition was held on Jan 1, 2022.

The Shenzhou-17 crew continue to research human adaptation to the space environment. So far, they have successfully completed many tasks, including spacewalks, moving equipment out of the space station for space experiments, managing equipment and facilities, and maintaining experiment facilities for long term science research.

Shenzhou-17 is the sixth crew of three astronauts on a mission to the China Space Station. Shenzhou-17 is also the twelfth crewed and seventeenth flight overall of China's Shenzhou spaceflight program.

Evidence for Neutron Star Inside SN 1987a Supernova Remnant | NASA Webb

Evidence for Neutron Star Inside SN 1987a Supernova Remnant | NASA Webb

The NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, occurred 160,000 light-years from Earth in the neighboring Large Magellanic Cloud galaxy. SN 1987A was a type II supernova that was observed on Earth in 1987, the first supernova that was visible to the naked eye since 1604—before the advent of telescopes. It provided the astronomical community a rare opportunity to study the evolution of a supernova and what was left behind, from the very beginning. SN 1987A was a core-collapse supernova, meaning the compacted remains at its core are expected to have formed either a neutron star or a black hole. Evidence for such a compact object has long been sought, and whilst indirect evidence for the presence of a neutron star has previously been found, this is the first time that the effects of high energy emission from the young neutron star has been detected.

LEFT: Webb’s 2023 NIRCam (Near-Infrared Camera) image of SN 1987A that highlights the object’s central structure, expanding with several thousands km/s. The blue region is the densest part of the clumpy ejecta, containing heavy elements like carbon, oxygen, magnesium and iron, as well as dust. The bright ‘ring of pearls’ is the result of the collision of the ejecta with a ring of gas ejected about 20,000 years before the explosion. Now spots are found even exterior to the ring, with diffuse emission surrounding it. These are the locations of supernova shocks hitting more exterior material from the progenitor star. The outer ejecta is now illuminated by X-rays from the collision, while the inner ejecta is powered mainly by radioactivity and a putative compact object.

RIGHT: An international team of astronomers has now used two of Webb’s instruments to study the emissions from the core of SN 1987A. The top image features the data from Webb’s MRS (Medium Resolution Spectrograph) mode of the MIRI instrument (Mid-InfraRed Instrument). The bottom image depicts data from Webb’s NIRSpec (Near Infrared Spectrograph) at shorter wavelengths. Spectral analysis of the MIRI results showed a strong signal due to ionized argon from the center of the ejected material that surrounds the original site of SN 1987A. The NIRSpec data found even more heavily ionized chemical species, particularly five times ionized argon (meaning argon atoms that have lost five of their 18 electrons). Weak lines of ionized sulphur were also detected with MIRI. This indicated to the science team that there is a source of high-energy radiation in the center of the SN 1987A remnant, illuminating an almost point-like region in the center. The most likely source is believed to be a newly born neutron star.

Image Description: A graphic with three images, each of a glowing, ring-shaped nebula. The left side shows a large, full-color image of the nebula and its surroundings, labelled “NIRCam”. A rectangle in the center of the nebula is highlighted and two images of this area are pulled out to the right. Both are shown in shades of orange. The top one is labelled “MIRI MRS Argon II” and the bottom one “NIRSpec IFU Argon VI.
