Space Stories: Remembering the Solar System Delivery System, Many More Milky Ways, and AI Investigates Alien Life

Here are some recent stories of interest.

—NASA: “New US Postage Stamp Commemorates NASA’s Asteroid Sample Delivery“

On Sept. 24, NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) spacecraft will speed past Earth and – at precisely the right moment – jettison its sample capsule containing material from asteroid Bennu…To help celebrate this engineering and scientific achievement, the U.S. Postal Service issued a commemorative stamp featuring an artist’s impression of the sample capsule as it parachutes to Earth over its landing site on the Department of Defense’s Utah Test and Training Range…Although OSIRIS-REx has already had many scientific accomplishments, at its heart, the mission’s research goals circle around the sample delivery from Bennu. That influenced the Postal Service’s decision to select the capsule’s descent as the subject of the new stamp.

—LiveScience.com: “James Webb Telescope Spots Thousands of Milky Way Lookalikes That ‘Shouldn’t Exist’ Swarming Across the Early Universe“

The James Webb Space Telescope (JWST) has found more than 1,000 galaxies mysteriously resembling our own Milky Way hiding out in the early universe. Shaped like warped vinyls and sporting delicate spiral arms, the Milky Way doppelgangers were found by JWST more than 10 billion years into the universe’s past — during a period when violent galactic mergers were thought to have made an abundance of such fragile galaxies impossible. Yet the disk galaxies are 10 times more common in the early universe than astronomers previously thought, new research reveals.

—Astronomy.com: “Can AI Find Life in the Universe?“

Scientists could soon use common lab technology along with sophisticated algorithms to answer one of the biggest questions in all of astronomy — are we alone in the universe? In new research published today in Proceedings of the National Academy of Sciences (PNAS), a team of scientists announced a novel technique that can take a sample of a material, feed it through a machine-learning algorithm, and find out if the material did — or didn’t — come from a living organism with 90 percent accuracy.

Future Plans for a Spaceship to Decommission the ISS

Posted on by onespaceman2000

How much does it cost to decommission a space station? Well, according to NASA as cited by London’s Daily Mail, it will cost at least $1 billion to ensure the International Space Station (ISS) finds a safe spot to crash. And NASA even has a name for the spacecraft that will be needed to steer the ISS into the Earth – the US Deorbit Vehicle (USDV) – because everything needs an fancy acronym.

The ISS is not expected to disappear until 2031, but plans are underway to start the decommissioning process now. If you want to help build the USDV you have until November of this year to share your plans with NASA (see below and visit this link). Just as we have companies in a race to put humans on the Moon again, we will now have a race for the final days of the ISS.

And where will the ISS end up? In its Requiremenst for Request Information, NASA is asking for a “controlled reentry into an unpopulated region.” It appears the goal is to aim any burning remains at Point Nemo, which is a spot in the Pacific Ocean used many times for such purposes (see the diagram above).

The US apparently has plans for an ISS replacement. I just hope at least part of the new station is in orbit by 2031. We do not need a long gap with no space station. The gap between end of the space shuttle and the restart of US-controlled rocket missions to the ISS was far too long. We have time to get it right.

Queen’s Brian May and Bennu?

I was surprised to hear from Queen’s Brian May regarding the recent landing of the asteroid Bennu sample in the Utah desert. Here is what he posted and stated on his page:

“Today is the day – the long awaited day – when the sample of a piece of material From Bennu – the asteroid most likely to hit the Earth in the future, is recovered to Earth. This box when it is opened of material from the surface of Bennu can tell us untold secret of the origins of the universe, the origins or our planet and the origins of life itself. What an incredibly exciting day. Tune into Nasa TV. Go to the OSIRIS-REx website. Read my new book for the full story – Bennu 3-D – written with leader of the mission, Dante Lauretta. And enjoy this wonderful forward step in our knowledge of the universe.”

As you can see above, Brian May is named on the book about the asteroid. He is also credited with assisting NASA with the location of the sample landing. I was not aware of his deep involvement with the Bennu mission, or astronomy in general. In addition to the points above, it is worth noted that Mr. May (per Wikipedia):

  • earned a PhD degree in astrophysics from Imperial College London in 2007;
  • was a “science team collaborator” with NASA’s New Horizons Pluto mission;
  • is a co-founder of the awareness campaign Asteroid Day; and
  • has an asteroid named after him – Asteroid 52665 Brianmay.

Pretty impressive for a guy with a singing day job.

Space Missions: Good News for an Asteroid Sample, But Bad News for a Lunar Rover

First, let discuss the good news. The capsule carrying the sample material from the asteroid Bennu successfully landed in the Utah desert earlier today, as planned. NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission was a success. The space agency has plenty to celebrate.

And now for the bad news. India’s Chandrayaan-3 moon lander as well as its lunar rover were supposed to wake up around September 22 with the return of sunlight to the Moon’s South Pole. Unfortunately, neither craft showed any signs of coming back online. That said, the India space agency still has plenty to celebrate given its ability to successfully explore the South Pole before night set in.

A Day in Autonomy: The Discovery of Neptune

On this day in 1846, astronomer Johann Gottfried Galle discovered the ice giant Neptune, the eighth and most distant planet in the solar system. Two other astronomers are credited with coming up with the mathematical calculations related to the discovery – France’s Urbain Le Verrier and England’s John Couch Adams.

Here are some interesting facts about the planet:

  • It is more than 30 times as far from the Sun as Earth;
  • It takes 165 Earth years to orbit the sun, meaning it has only completed one full orbit since it was discovered;
  • It is about four times wider than Earth;
  • It has at least five main rings and four prominent ring arcs; and
  • It lacks a solid surface.
