NASA’s Ingenuity helicopter on Mars has exceeded everyone’s expectations, recently completing its 51st flight when it was supposed to fly just a few times as a demonstration mission. But flights 50 and 51 almost didn’t happen.
In a recent blog post, Travis Brown, Chief Engineer for Ingenuity shared how the team lost contact with the tiny rotorcraft for six excruciating days.

With Virgin Orbit going through bankruptcy, other launch providers are purchasing various parts of the business. This week we learned that Stratolaunch’s bid to buy Virgin Orbit’s modified Boeing 747 carrier aircraft has been approved by the U.S Bankruptcy Court, enabling Stratolaunch to use the 747 to carry its Talon-A hypersonic vehicles, ideally beginning operation by 2024.

The James Webb Space Telescope has observed a huge water vapor plume emanating from Saturn’s moon Enceladus. Astronomers say the plume reaches nearly 10,000 kilometers (6,200 miles) into space, which is about the equivalent distance as going from Ireland to Japan. This is the largest plume ever detected at Enceladus.

As NASA prepares to return astronauts to the Moon with Artemis III, China is ramping up its efforts for a crewed lunar landing, targeting earlier than 2030. Lin Xiqiang, the deputy director of China’s Manned Space Agency announced that the Chinese Lunar Exploration Program (CLEP) is preparing for a “short stay on the lunar surface and human-robotic joint exploration.”

New images from NASA’s Lunar Reconnaissance Orbiter (LRO) appear to show the crash site where the Japanese Hakuto-R Mission 1 lunar lander impacted the surface of the Moon a month ago.
The refrigerator-sized HAKUTO-R was built by the startup company iSpace and was launched in December 2022 with the goal of becoming the first commercial lunar lander to touch down safely on the Moon. However, during landing operations on April 25, 2023, communications ceased just moments before touchdown should have occurred, and the lander was presumed lost.

Have you noticed a lack of gravitational wave announcements the past couple of years? Well, now it is time to get ready for an onslaught, as the Laser Interferometric Gravitational-Wave Observatory (LIGO) starts a new 20-month observation run today, May 24th after a 3-year hiatus.
LIGO has been offline for the last three years, getting some serious new upgrades. One upgrade, called “quantum squeezing,” reduces detector noise to improve its ability to sense gravitational waves.
Astronomers expect this upgrade could double the sensitivity of LIGO. This will allow black hole mergers to be seen more clearly, and it could also allow LIGO to see mergers that are fainter or farther away. Or, perhaps it could even detect new kinds of mergers that have never been seen before.

Uranus takes 84 years to orbit the Sun, and so that last time that planet’s north polar region was pointed at Earth, radio telescope technology was in its infancy.
But now, scientists have been using radio telescopes like the Very Large Array (VLA) the past few years as Uranus has slowly revealing more and more of its north pole. VLA microwave observations from 2021 and 2022 show a giant cyclone swirling around this region, with a bright, compact spot centered at Uranus’ pole. Data also reveals patterns in temperature, zonal wind speed and trace gas variations consistent with a polar cyclone.

On Sunday, May 21, the 4-person crew of Axiom Mission 2 (Ax-2) blasted off to the International Space Station (ISS) on board a SpaceX Crew Dragon, and today, May 22, the private astronaut crew boarded the International Space Station for a scheduled 10-day stay.

Astronomers think they’ve found an extrasolar planet covered in volcanoes like Jupiter’s moon Io, but this world is about the same size as Earth. Designated LP 791-18 d, the planet is probably tidally locked around a small, red dwarf star about 90 light-years away in the constellation Crater. There are two other more massive planets in the system, and their tidal interactions could cause enough tidal flexing that it unleashes planet-wide volcanoes on LP 791-18 d.
Planet d is located within the habitable zone of the star, and with all the other conditions, astronomers think it might be temperate enough on the permanent night side of this world to allow water to exist.

Another of NASA’s top human spaceflight officials has joined SpaceX. Kathy Leuders, the former associate administrator for NASA’s Space Operations Mission Directorate, retired from NASA on May 1 after 31 years of service. But this week, CNBC reports that Lueders has joined SpaceX at the company’s Starbase facility in Texas. She follows Bill Gerstenmaier, who retired from NASA in 2020 and became a senior executive at SpaceX as build and flight reliability vice president.
