Earlier today, the European Space Agency (ESA) successfully launched an Ariane 6 rocket, the next generation of European space rockets. The launch was from the ESA’s Guiana Space Centre in French Guiana.

Europe is once again moving away from it dependence on US and Russian rockets to get its space program into space. The launch of the new rocket has been delayed for years while the Ariane 5 flew its last mission about a year ago.

On it’s Twitter page, the ESA stated:

We have now entered into a new era of spaceflight for Europe, powering us into space and allowing us to realise our ambitions on the world stage.

The inaugural flight did experience a problem when part of its test payload failed to deploy. This will need to be investigated and corrected before more critical payloads are placed on a rocket.

That said, all in all it was a good day for the Europeans and space enthusiasts everywhere.

Space Stories: Fewer Eyes on Asteroids, Volunteer Martians Released, and Russians Plans for a New Space Station

Here are some recent stories of interest.

—Flying Magazine: “NASA’s Asteroid, Comet Hunting Telescope Set to Retire at End of Month“

A NASA space telescope designed to “hunt” asteroids and comets that could pose a threat to life on Earth and orbiting spacecraft will soon burn up in orbit. In late 2024 or early 2025, the agency’s Near-Earth Object (NEO) Wide-field Infrared Survey Explorer—or NEOWISE—is expected to come home in pieces following the conclusion of its second mission later this month…However, NASA has a replacement lined up: the Near Earth Object Surveyor (NEO Surveyor), set for a 2027 launch. The infrared space telescope is the first to be designed specifically for hunting large numbers of NEOs in and around Earth orbit. It has a baseline development cost of $1.2 billion to which NASA committed in 2022.

—NPR: “Volunteers Who Lived in a NASA-created Mars Replica for Over a Year Have Emerged“

Four volunteers who spent more than a year living in a 1,700-square-foot space created by NASA to simulate the environment on Mars have emerged. The members of the Crew Health and Performance Exploration Analog mission — or CHAPEA — walked through the door of their habitat at NASA’s Johnson Space Center in Houston on Saturday to a round of applause…Haston and the other three crew members — Anca Selariu, Ross Brockwell and Nathan Jones — entered the 3D-printed Mars replica on June 25, 2023, as part of a NASA experiment to observe how humans would fare living on the Red Planet.

—Reuters: “Russia Plans to Create Core of New Space Station by 2030“

Russia is aiming to create the four-module core of its planned new orbital space station by 2030, its Roscosmos space agency said on Tuesday. The head of Roscosmos, Yuri Borisov, signed off on the timetable with the directors of 19 enterprises involved in creating the new station. The agency confirmed plans to launch an initial scientific and energy module in 2027. It said three more modules would be added by 2030 and a further two between 2031 and 2033.

Podcast: Alan Alda Interviews Astronaut Cady Coleman

Posted on by onespaceman2000

If you missed it, check out Alan Alda’s podcast Clear & Vivid for his recent interview with NASA astronaut Cady Coleman.

It’s a thoughtful interview as only Mr. Alda can do it. Ms. Coleman discusses her experiences on the International Space Station (ISS), which she calls a “floating palace.” Ms. Coleman has been part of three space missions, including two space shuttle missions as well as a stay on the ISS.

Ms. Coleman discusses funny episodes in her career, such as losing control of bbq sauce in zero gravity, as well as her overall feeling that the ISS represents something positive for all of humanity, regardless of the crazy movie plots where the astronauts and cosmonauts are at each other’s throats. She pointed out that the ISS was nominated for a Nobel peace prize back in 2014, which she thought was an appropriate gesture.

Overall, its a good conversation that may give you more insight into how one lives in space in such tight quarters.

Listen in if you get a chance.

Study Findings: Which Caves on Mars are Safe to Live In?

Here are some highlights from the paper presented at the 55th Lunar and Planetary Science Conference:

For reliable protection against cosmic radiation, living and working spaces for colonists are best built below the surface. These colonies also need to be provided with energy. And solar panels are not the best option because the solar radiation flux is much lower on Mars and the panels will be constantly dusted with dust due to frequent dust storms. A nuclear reactor may be the best option.

Humans also need constant access to water resources. From the point of view of the reliability of the future housing, a lava tube with strong walls best meets these requirements. It is a hollow formation in the crust, formed as a result of the release of volcanic lava. And based on the need to provide settlements with water, a more suitable case should be considered underground caves in glacial cracks with a gentle horizontal entrance. After all, there are already significant deposits of water ice under the surface. But the walls of such settlements will be less strong, and they will require more careful preparatory work.

More on the Recent Asteroid Flybys

Remember asteroid 2024 MK from last Saturday? Well, NASA has some nice shots (shown above) of the asteroid as it made it close approach to the Earth. It shows the 500 foot-wide asteroid in all of its scary glory. We were lucky to be nothing but observers that day.

Another asteroid that shot by the Earth on June 27th at a distance that was about 17 time the distance between the Earth and the Moon was asteroid UL21. This asteroid was not a surprise, having been spotted back in 2011. However, it had a surprise when viewed up close. The asteroid had its own moon (shown below).

I’m impressed we have these amazing images, but if they price for these images is a risky rendezvous then I can live without them.

Note: Another asteroid is coming our way next week – asteroid 2024 MT1. The asteroid is 260 feet in diameter and will be come much closer than UL21, or about four times the distance between the Earth and the Moon.
