—NPR: “Hubble will Change How it Points, But NASA Says ‘Great Science’ will Continue“

The Hubble Space Telescope is suffering the kinds of aches and pains that can come with being old, and NASA officials say they’re shifting into a new way of pointing the telescope in order to work around a piece of hardware that’s become intolerably glitchy. Officials also announced that, for now, they’ve decided not to pursue a plan put forward by a wealthy private astronaut who wanted to go to Hubble in a SpaceX capsule, in a mission aimed at extending the telescope’s lifespan by boosting it up into a higher orbit and perhaps even adding new technology to enhance its operations.

—NASA: “NASA Awards Advance Technologies for Future Habitable Worlds Mission“

NASA announced Friday it selected three industry proposals to help develop technologies for future large space telescopes and plan for the agency’s Habitable Worlds Observatory mission concept, which could be the first space telescope designed to search for life outside our solar system. The mission would directly image Earth-like planets around stars like our Sun and study their atmospheres for the chemical signatures of life, as well as enable other investigations about our solar system and universe. NASA is currently in the early planning stages for this mission concept, with community-wide working groups exploring its fundamental science goals and how best to pursue them. The agency is also in the process of establishing a Habitable Worlds Observatory Technology Maturation project office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

—Southwest Research Institute: “Flyby of Asteroid Dinkinesh Reveals a Surprisingly Complex History“

When NASA’s Lucy spacecraft flew past the tiny main belt asteroid Dinkinesh last November, the Southwest Research Institute-led mission discovered a trough and ridge structure on the main asteroid as well as the first-ever-encountered contact binary satellite. The flyby data of this half-mile-wide object revealed a dramatic history of sudden breakups and transformation. Scientists think a big chunk of Dinkinesh suddenly shifted, excavating the trough and flinging debris into its vicinity. Some materials fell back to the asteroid body, forming the ridge, while others coalesced to form a contact binary satellite known as Selam. The complex shapes show that Dinkinesh and Selam have significant internal strength and a complex, dynamic history.

Video: Check Out Aeon Astronomy & Space Travel Videos

Aeon is a website of ideas run by Aeon Media. It’s mission is to explore and communicate knowledge that addresses our shared need to make sense of the world.

While it covers quite a few topics, I wanted to highlight some of its videos on astronomy and space travel. Below are just a few I recommend. You should explore the site on your own to learn more.

Check them out and many more. It is a well organized site that operates on donations, so don’t be afraid to contribute if you really enjoy the pieces.

—NDTV: “NASA’s Mission Not Only Altered Asteroid’s Path, But Its Shape Too, Says New Study“

A recent study suggests NASA’s DART mission, designed to test asteroid deflection methods, may have revealed more than planned. While successfully altering the target asteroid’s trajectory, scientists now believe the impact also significantly changed its shape, hinting at a surprising composition. Previously thought to be a solid rock, Dimorphos, the impacted asteroid, may actually be a loose collection of debris. This conclusion stems from the unexpected level of deformation observed after the collision. Unlike a typical crater, the impact appears to have caused a broader, flatter dent, resembling an M&M candy.

—Reuters: “India Announces Four-member Crew for ‘Gaganyaan’ Space Mission“

India on Tuesday introduced four crew members for its maiden ‘Gaganyaan’ space voyage, as it aims to become the world’s fourth country to send a crewed mission into space just months after a historic landing on the south pole of the moon. Gaganyaan, or “sky craft” in Hindi, is the first mission of its kind for India and will cost about 90.23 billion rupees ($1.1 billion). It involves the launch of a habitable space capsule over the next year to an orbit of 400 km (250 miles) and its return via a landing in the Indian Ocean.

Japan’s space agency made contact with its SLIM moon lander Sunday, despite the spacecraft not being expected to function after lunar night. Contact with the Smart Lander for Investigating Moon (SLIM) spacecraft was reestablished on Sunday, Feb. 25, the Japan Aerospace Exploration Agency (JAXA) announced via its dedicated SLIM account on X, formerly known as Twitter, early Feb. 26.

Space Stories: A Test of Space Suits, Water Detected on Asteroids, and China’s Growing Space Program

—The Verge: “One of NASA’s New Spacesuits Passes Microgravity Test“

Collins Aerospace, a private company hired to create spacesuits for use outside the International Space Station (ISS), has tested its suit aboard a commercial microgravity flight, passing a milestone that lets engineers move forward toward critical design review…During the test, the plane executed “roller-coaster-like maneuvers” to induce weightlessness and allow someone wearing a prototype to see if it actually lets someone move around in it under those conditions.

—Newsweek: “NASA Data Detects Water on Asteroids for the First Time Ever“

Water has been found on the surface of two asteroids for the first time, scientists said in a new paper. Two silicate-rich asteroids were detected by the retired Stratospheric Observatory for Infrared Astronomy (SOFIA) that were giving off a specific wavelength of light that indicated the presence of molecules of water, according to research published in The Planetary Science Journal. The discovery may have major implications for theories about how water initially made its way to our own planet. It could have been delivered via asteroid impact.

—Astronomy.com: “China is Embarking on a Science and Exploration Program of Staggering Scale“

When China’s first lunar lander, Chang’e 3, touched down in Mare Imbrium on the Moon in 2013, it was the pinnacle of the country’s space endeavors. The robotic lander and its small Yutu rover companion were the first spacecraft to operate on the Moon since the 1970s, and provided new insights into our planet’s natural satellite…Since then, China’s space activities have exploded in range, frequency, and ambition. The country now rivals the U.S. for the most launches per year, with around 80 missions having been planned for 2023. The nation has its own modular space station, named Tiangong, which is expected to be continuously occupied by a rotating crew of three astronauts for at least a decade.

Sample Return: NASA Just Needed the Right Tool

It is amazing that we have the ability to launch a spacecraft that can chase an asteroid millions of miles away, but we lack a wrench here on Earth to open the sample container when some of that asteroid is sent home.

You may remember the problems NASA had last year opening the lid on the sample canister that Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) returned from its encounter with the asteroid Bennu. Well, NASA finally opened up the canister.

NASA stated:

Curation processors paused disassembly of the TAGSAM head hardware in mid-October after they discovered that two of the 35 fasteners could not be removed with the tools approved for use inside the OSIRIS-REx glovebox. In response, two new multi-part tools were designed and fabricated to support further disassembly of the TAGSAM head. These tools include newly custom-fabricated bits made from a specific grade of surgical, non-magnetic stainless steel; the hardest metal approved for use in the pristine curation gloveboxes.

That’s a lengthy way to simply say we found the right tool. Now the rest of the asteroid sample can be cataloged and shared with the scientific community.

I am just glad the capsule did not contain an astronaut.
