Enhanced Software for Removing Satellite Streaks from Hubble Space Telescope Images
Researchers at the Space Telescope Science Institute have developed software based on the Radon Transform to identify and remove satellite streaks from Hubble Space Telescope images. The software is 10 times more sensitive than previous methods and can identify twice as many streaks. It flags affected pixels, allowing for their removal and the recovery of clean images. This tool enhances the cleaning and calibration of Hubble data, improving observations.
Valentina Tereshkova and Sally Ride – Women Space Pioneers
Valentina Tereshkova was born on March 6, 1937, in the Soviet Union (now Russia). She became the first woman to travel to space on June 16, 1963, aboard the Vostok 6 spacecraft. Tereshkova orbited the Earth 48 times during her three-day mission. She was a skilled parachutist and had undergone extensive training before her historic flight. Tereshkova later became a prominent political figure and served as a representative in the Soviet Union’s Supreme Soviet. She remains an iconic figure in space exploration as the first woman to reach space.
Sally Ride was born on May 26, 1951, in the United States and became the first American woman to travel to space. On June 18, 1983, she flew aboard the Space Shuttle Challenger as a mission specialist on STS-7. Ride’s journey marked a significant milestone for women in space exploration. She went on to complete a second spaceflight in 1984 and served as a member of the investigation team following the Challenger disaster in 1986. Ride later transitioned into a career as an educator and advocate for science education, particularly for young girls. Her accomplishments and contributions have inspired many women to pursue careers in STEM fields
NASA has selected the astronaut team for the Artemis 2 lunar mission
The crew consists of Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen. The Artemis 2 crew is expected to be the first astronauts to go to the Moon since the Apollo program. The mission will not involve a lunar landing but will follow a hybrid free-return trajectory. After the 10-day mission, the crew will return to Earth. The mission will be carried out using NASA’s Orion spacecraft and is targeted for launch in late 2024.
Water, water everywhere, including the icy moons of Uranus
Hidden oceans beneath frozen moons in the outer solar system are a hot topic in planetary astronomy. Re-analysis of Voyager 2 data suggests Uranus’ moons Ariel, Umbriel, Titania, and Oberon may have oceans beneath their icy surfaces. The study combines data from multiple missions, revealing the moons’ porosity and potential for liquid oceans. Heat sources like radioactive decay and abundant substances like chlorides and ammonia may play a role. More research is needed to understand these mechanisms and plan future observations.
FIRST WOMAN GRAPHIC NOVELS
First Woman tells the tale of Callie Rodriguez, the first woman to explore the Moon. While Callie is a fictional character, the first female astronaut and person of color will soon set foot on the Moon – a historic milestone and part of upcoming NASA Artemis missions. Through a series of graphic novels and digital platforms, First Woman aims to captivate audiences and inspire the next generation of explorers who will return to the Moon.
