Russian Cosmonauts on Spacewalk | International Space Station
Cosmonauts Sergey Prokopyev and Dmitri Petelin of Russia spent seven hours and 54 minutes outside the International Space Station today. Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin concluded their spacewalk on Tuesday, April 19, 2023, at 5:35 a.m. EDT after seven hours and 55 minutes.
Prokopyev and Petelin completed their major objectives, which included relocating a radiator from the Rassvet module to the Nauka science module with assistance from European robotic arm operator cosmonaut Andrey Fedyaev.
This was the fourth spacewalk in Prokopyev’s career, and the second for Petelin. It is the third spacewalk at the station in 2023 and the 260th spacewalk for space station assembly, maintenance, and upgrades.
The two Roscosmos cosmonauts will also conduct a spacewalk on Tuesday, April 25, to relocate an experiment airlock from Rassvet to Nauka.
An additional spacewalk is planned on Thursday, May 4, to deploy the radiator on Nauka and connect mechanical, electrical, and hydraulic lines.

Planet Jupiter & Ganymede—Largest Moon in Our Solar System | NASA Juno
Ganymede (visible in the top-left corner) is the largest natural satellite of Jupiter as well as the biggest moon in our Solar System. Ganymede is also the largest Solar System object without an atmosphere, despite being the only moon of the Solar System with a magnetic field. Like Saturn's moon Titan, Ganymede is larger than planet Mercury. However, Ganymede has less surface gravity than Mercury, Io or the Moon.
Goal: Understand origin and evolution of Jupiter, look for solid planetary core, map magnetic field, measure water and ammonia in deep atmosphere, observe auroras.
The Jet Propulsion Laboratory (JPL) manages the Juno mission for NASA. The mission's principal investigator is Scott Bolton of the Southwest Research Institute in San Antonio. The mission is part of NASA's New Frontiers Program, managed at the agency's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate. Lockheed Martin Space Systems in Denver built the spacecraft.

Zoom-in on Galaxies NGC 4298 & NGC 4302 | Hubble & Ground Views
This video starts with a view of the night sky as seen from the ground and zooms in onto the Virgo Cluster of galaxies. A further zoom shows the two galaxies NGC 4298 and NGC 4302 as they are seen by Hubble. Distance: 55 million light-years
This video pans over NASA/European Space Agency Hubble Space Telescope observations of the two galaxies known as NGC 4298 and NGC 4302. Distance: 55 million light-years away
Galaxy NGC 4298 is seen almost face-on, allowing us to see its spiral arms and the blue patches of ongoing star formation and young stars. In the edge-on disc of NGC 4302 huge swathes of dust are responsible for the mottled brown patterns, but a burst of blue to the side of the galaxy is indicating a region of extremely vigorous star formation.
A Close Galactic Pair: Galaxies NGC 4302 & NGC 4298 | Hubble
This image displays the galaxies NGC 4302—seen edge-on—and NGC 4298, both located 55 million light-years away. The galaxy NGC 4298 is seen almost face-on, allowing us to see its spiral arms and the blue patches of ongoing star formation and young stars. In the edge-on disc of NGC 4302 huge swathes of dust are responsible for the mottled brown patterns, but a burst of blue to the left side of the galaxy indicates a region of extremely vigorous star formation.
The image is a mosaic of four separate captures from Hubble, taken between January 2 and 22, 2017, that have been stitched together to give this amazing field of view. Two different types of light emitted by the galaxies—visible and near-infrared—have been combined to give a rich and colorful image. This light was captured by Hubble’s Wide Field Camera 3, one of the telescope’s most advanced imaging instruments.

Neutron Star Merger Animation Ending with Kilonova Explosion
This artist’s impression video shows how two tiny but very dense neutron stars merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves and a short gamma-ray burst, both of which were observed on August 17, 2017, by LIGO–Virgo and Fermi/INTEGRAL respectively. Subsequent detailed observations with the NASA/European Space Agency Hubble Space Telescope and other telescopes all over the world have confirmed that this object, seen in the galaxy NGC 4993 about 130 million light-years from the Earth, is indeed a kilonova. These objects are the main source of very heavy chemical elements, such as gold and platinum, in the Universe.

Zoom into Lenticular Galaxy NGC 4993 and Kilonova | Hubble
This video zooms from a ground-based view on towards the lenticular galaxy NGC 4993 in the constellation Hydra. Within this galaxy, a neutron star collision generated gravitational waves and an associated gamma-ray burst. It also resulted in an explosion called a kilonova that was visible to telescopes including the NASA/ESA Hubble Space Telescope.
The zoom ends with a loop of the three Hubble observations made in the first days after the explosion, clearly showing the evolution of the coloor and brightness of the kilonovoa.
Lenticular Galaxy NGC 4993: Kilonova Detected | Hubble
The lenticular galaxy NGC 4993 is located about 130 million light-years from Earth. On August 17, 2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo Interferometer both detected gravitational waves from the collision of two neutron stars within this galaxy. The event also resulted in a flare of light, called a kilonova, which is visible to the upper left of the galactic center in this image from the NASA/European Space Agency Hubble Space Telescope. A "kilonova" is a powerful event that happens when two neutron stars merge.
NASA Launches StratosphericSuper Pressure Balloon from New Zealand
NASA’s Scientific Balloon Program successfully launched its football-stadium-sized, heavy-lift super pressure balloon (SPB) from Wānaka Airport, New Zealand, at 11:42 a.m., Sunday, April 16, 2023, (7:42 p.m.. April 15 in U.S. Eastern Time), on a mission planned for 100 or more days. The balloon will float at 110,000 feet (33.5 km) with the winds carrying it about the southern hemisphere's mid-latitude band.
While validating the super pressure balloon technology is the main flight objective, the balloon is also carrying the Super Pressure Balloon Imaging Telescope (SuperBIT), from Princeton University, which uses a wide field of view to image large galaxy clusters from a balloon platform in a near-space environment.
The 18.8-million-cubic-foot (532,000-cubic-meter) balloon is helium-filled and about the size of a football stadium when fully inflated at its operational float altitude of 110,000 feet (33.5 kilometers). Wānaka is NASA’s dedicated launch site for mid-latitude, long-duration balloon missions.
NASA invites the public to follow these missions as they fly on their globetrotting journeys about the Southern Hemisphere’s mid-latitudes. A balloon’s flight path is controlled by the wind speed and direction at float altitude. The missions will spend most of their time over water, and for any land crossings, NASA works with the U.S. State Department to coordinate country overflight approvals. Real-time tracking of these flights is publicly available here:
Interviewing Wally Funk: Aviation Pioneer | National Air and Space Museum
Funk became the oldest woman to go to space on July 20, 2021, at age 82, flying on Blue Origin's New Shepard spacecraft during its suborbital flight. Flying airplanes was something that Wally Funk always wanted to do. She had her first flying lesson when she was nine years old and by twenty had become a professional aviator. In 1961, she volunteered for the “Women in Space” program with the hope of becoming an astronaut. Wally was one of thirteen women who, despite having passed all of the rigorous testing proving they were physically and psychologically qualified for space travel, were denied the chance to become astronauts when the program was canceled. In 1974, Funk was hired by the National Transportation Safety Board (NTSB) as its first female Air Safety Investigator. Funk continued to dream of going into space and in July 2021 achieved her dream.
