A little humor in the title but serious science - the Moon is shrinking due to heat loss as is explained in this article.

The findings are based on the study of 12,000 photographs taken by Lunar Reconnaissance Orbiter (LRO)  - the spacecraft that continues to rewrite what we know about the Moon - showing new wrinkle features in the northern part of the Moon known as Mare Frigoris.

Region of the Moon called Mare Frigoris
Scientists have discovered these wrinkle ridges in a region of the Moon called Mare Frigoris. These ridges add to evidence that the Moon has an actively changing surface. This image was taken by NASA's Lunar Reconnaissance Orbiter (LRO).

The shrinking Moon also is thought to have created "moonquakes" that shaped the Moon's surface, especially in Taurus-Littrow Valley where Apollo 17 astronauts Gene Cernan and Harrison Schmidt (the only geologist to to the Moon so far).

An amazing view of Taurus Littrow Valley by LRO:

The Taurus-Littrow valley is the location of the Apollo 17 landing site (asterisk). Cutting across the valley, just above the landing site, is the Lee-Lincoln fault scarp. Movement on the fault was the likely source of numerous moonquakes that triggered events in the valley. 1) Large landslides on of slopes of South Massif draped relatively bright rocks and dust (regolith) on and over the Lee-Lincoln scarp. 2) Boulders rolled down the slopes of North Massif leaving tracks or narrow troughs in the regolith on the slopes of North Massif. 3) Landslides on southeastern slopes of the Sculptured Hills.

Hey Space Placers!

Here is an excellent Washington Post article on upcoming research that will be performed on pristine Apollo lunar samples that have been preserved for the past half century.

This research will be epic because these samples were preserved by NASA nearly 50 years ago with the express intent of waiting for the development of new techniques and instruments to learn new things about the Moon. That time has come later this year.

We know alot about the Moon from prior studies of the Apollo lunar samples  but we are learning more with new methods and instruments. But to study PRISTINE, sealed and frozen samples with these methods - well, it is like a whole new mission to the Moon. We are going to learn so much I do believe.

I will have more on this exciting story as it develops.

It is scheduled for launch between July 9 and 16. The lander and rover are scheduled to land near the South Pole, a very interesting region of the Moon that has never been explored by a lander/rover. It is known to harbor frozen water ice in a likely mix with the lunar soil in permanently shadowed craters.

Hey Space Placers!

Just about everything you see in this pic from Hubble Space Telescope (HST) is a galaxy - about 265,000 of them! 

Hubble's Wide View of the Evolving Universe
This Hubble Space Telescope image represents the largest, most comprehensive "history book" of galaxies in the universe.
The image, a combination of nearly 7,500 separate Hubble exposures, represents 16 years' worth of observations.
The ambitious endeavor, called the Hubble Legacy Field, includes several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time.
The image mosaic presents a wide portrait of the distant universe and contains roughly 265,000 galaxies. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang. The tiny, faint, most distant galaxies in the image are similar to the seedling villages from which today's great galaxy star-cities grew. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see.
The wider view contains about 30 times as many galaxies as in the Hubble Ultra Deep Field, taken in 2004. The new portrait, a mosaic of multiple snapshots, covers almost the width of the full Moon. Lying in this region is the XDF, which penetrated deeper into space than this legacy field view. However, the XDF field covers less than one-tenth of the full Moon's diameter.

Hey Space Placers!

On April 23, 2019 there was a bright bolide (exploding meteor/fireball) over Costa Rica. You may recall that in February 2019 a similar event happened over a village in Cuba and meteorites were recovered.

This Costa Rica meteorite event - known as a fall because space rocks have been recovered - is pretty amazing. Why? Because the type of meteorite that caused it, initially classified as a "CM", is very rare.

NASA scientists TODAY are flying and enroute to meet with Mike Farmer, a meteorite hunter/dealer I have known and bought from for decades, to obtain samples of this newest space rock from him. It is very possible that this fall came from a known dead/inactive comet.

I talked with Mike today about fall this before he was set to leave for Costa Rica for more hunting. He shared with me this incredible photo of a recovered meteorite from this fall and said I could share it:

4/23/19 Costa Rica Fall
Individual Meteorite
Credit: Robert Ward photo via Mike Farmer 
In decades of studying meteorites I have NEVER seen anything like this. The color is real and the specimen was collected before rain occurred so it is as fresh as an Earth specimen can be. What is that BLUE color?

The black color is fusion crust which is about 2mm thick and formed when the outer surface is melted by the friction of entering the Earth's atmosphere and only lasts a few seconds. We know that CM meteorites contain a LOT of chemical compounds and are of great interest in learning about our solar system.

The Murchison Meteorite reminds me of this fall and I think that this space rock will get a great deal of scientific attention.

Be sure to visit Mike's website if you are interested in purchasing genuine meteorites, including this one.

Today we are leaving the solar system WAY behind and heading out into the Universe because of BIG NEWS from the world of gravitational waves - see my previous blogs.

On April 1, 2019 the newly upgraded Laser Interferometer Gravitational-wave Observatory (LIGO) LIGO and Virgo Observatory in Italy went back on line. And shortly thereafter new discoveries followed.

A second neutron star merger was discovered and maybe, just maybe, the first ever merger of a black hole and neutron star.

The astronomical jury is compiling more data to try and see if this really was observed. It is a detection event that is eagerly anticipated.

The other big news is that with this upgrade it is predicted that a new black hole merger will be detected EVERY WEEK with a merger of neutron stars EVERY MONTH!   WOW!!!

Hey Space Placers!

Read the latest about humanity's fight against asteroids that threaten us.

Really important also in this fight is detection - you can't fight them if you can't see them coming.

Important to detection is NASA's NEOCam.  It will detect many Near Earth Objects (NEOs) especially those that we cannot see from Earth due to the Sun. Dr. Amy Mainzer has been working on  NEOCam and has also been the Primary Investigator for NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission. 

Comet C/2018 Y1 Iwamoto as imaged in multiple exposures of infrared light by the NEOWISE space telescope. The infrared images were taken on Feb. 25, 2019, when the comet was about 56 million miles, or 90 million kilometers, from Earth. C/2018 Y1 Iwamoto is a long-period comet originally from the Oort Cloud and coming in near the Sun for the first time in over 1,000 years.
Appearing as a string of red dots, this comet can be seen in a series of exposures captured by the spacecraft. Infrared light detected by the 3.4-micron channel is mapped to blue and green, while light from the 4.6-micron channel is mapped to red. In this image, stars show up as blue because they are hotter, whereas the cooler dust around the comet - with a temperature near the freezing point of water - glows red.
Credit: NASA JPL-Caltech
NEOWISE released its fifth year of survey data on April 11, 2019. The five years of NEOWISE data have significantly advanced scientists’ knowledge of asteroids and comets in the solar system, as well as the stars and galaxies beyond.

Unfortunately the lunar lander failed to safely make it to the surface according to SpaceIL on Twitter. A selfie image was taken of the spacecraft  22km above the Moon and the landing attempt proceeded. Apparently the main engine failed during the final descent at 150 meters from the surface.

Hey Space Placers!

Back on land and through March Madness with my Virginia Cavaliers winning the Men's Basketball National Championship.

Huge space news today and tomorrow - private Israeli spacecraft attempting Moon landing.

Today, April 10th, 2019 will be a historic date in the history of science as it was the day humanity saw the first ever image of a supermassive black hole. Get the details here and here.

Here is M-87's supermassive black hole taken with the Event Horizon Telescope (EHT).

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. Credit: Event Horizon Telescope Collaboration

This video shows you where M-87 is in the sky and takes you into the heart of the galaxy to reveal the above image: 
This zoom video starts with a view of ALMA and zooms in on the heart of M87, showing successively more detailed observations and culminating in the first direct visual evidence of a supermassive black hole’s shadow.

If you want to experience a breath taking ride into a supermassive black hole like M-87, go to a dark room with all of the lights off, set your computer's display to full brightness and full screen and WATCH THIS VIDEO!  IT IS STUNNING.....IT ALMOST GAVE ME VERTIGO!

This virtual reality simulation by Jordy Davelaar and colleagues shows a black hole surrounded by luminous matter. This matter disappears into the black hole in a vortex-like way, and the extreme conditions cause it to become a glowing plasma. The light emitted is then deflected and deformed by the powerful gravity of the black hole.

EHT also took data over a year ago on our Milky Way Galaxy's own supermassive black hole, Sagittarius A* (Sgr A*). It is a 4.4 million solar mass beast at the center of our galaxy. Today I telephonically contacted Peter D. Edmonds, Public Information Officer, Center for Astrophysics, Harvard & Smithsonian, to ascertain the status of the Sgr A* image. 

He stated, "That's a good question. The Sgr A* EHT image work is quite complicated and it is ongoing. We currently do not have a release date for that image."

Hopefully one day we will see the image of our galaxy's resident black hole. When we do that will be another historic day.

If your weather is clear for 4/2/19, and you have a good, unobstructed view of the Eastern horizon, make sure you get out about 30 minutes before local sunrise (check your local sunrise time) to see a nice sky sight.

Depending on whether you are in the Northern or Southern Hemisphere impacts how well you will see the very old Waning Crescent Moon, Venus and Mercury. This sky sight favors the Southern Hemisphere as the three will be higher in the sky.

For Northern Hemisphere observers if you have binoculars it will help to look for bright Venus first. The Moon will be directly below it with Mercury to the left.

This is an absolutely incredible scientific find - fossils and tektites from the actual day, if not the HOUR,  the dinosaurs died has been found in a layer of soil in a place called appropriately Hell Creek, North Dakota.

A meteor impact 66 million years ago generated a tsunami-like wave in an inland sea that killed and buried fish, mammals, insects and a dinosaur, the first victims of Earth’s last mass extinction event. The death scene from within an hour of the impact has been excavated at an unprecedented fossil site in North Dakota.

Comet or asteroid?

Hubble image of asteroid (6478) Gault
This Hubble Space Telescope image reveals the gradual self-destruction of an asteroid, whose ejected dusty material has formed two long, thin, comet-like tails. The longer tail stretches more than 500,000 miles (800,000 kilometers) and is roughly 3,000 miles (4,800 kilometers) wide. The shorter tail is about a quarter as long. The streamers will eventually disperse into space.

Dust is EVERYWHERE! You may have thought it was only something you have to contend with in your home, car, everywhere. But dust abounds in the Universe.

Dust rings in the inner solar system

The prevailing theory as to how planets form involves dust and far larger solid fragments that form rings around new born stars. These rings are thought to eventually coalesce into protoplanets and finally planets over time.

A new discovery of just that happening was announced with an accompanying photograph.

Fuzzy concentric rings, the inner one more distinct and brighter, around an orange dot.

With over 4000 planets beyond our solar system having been discovered to date, this is a routine byproduct of stellar birth. It is estimated that a few TRILLION planets orbit the hundreds of BILLIONS of stars in our galaxy alone. Astronomers are discovering more exoplanets almost weekly.

Read this story about the announcement from the Administration to land astronauts on the Moon in five years.

Here's my two cents worth on this.

No buck$, no Buck Roger$.

Unless this Administration does more than talk a good game this is as meaningless as Bush's speech in 2004 announcing the Constellation Program.

Remember the push for Apollo and the Space Shuttle to "go, go, go"? Safety essentially went out the window and we got the Apollo 1 and  Challenger disasters as a result.

Until REAL money is added to NASA's budget this is political theater.

I can assure you China is on track for the Moon to include landing Taikonauts. Russia is way behind with no proven rocket or crew-rated spacecraft or lander cut from metal.

I know it is not favored by some but the Lunar Gateway makes a LOT of sense for protracted and wide ranging lunar orbital and surface missions.

More bad news for Boeing.

Boeing is pushing back the maiden launch of an uncrewed Starliner from April to at least August.

Top notch reporting by the Washington Post gives us the inside scoop on Boeing issues with the Space Launch System (SLS)    and     this additional article on the Starliner.

What I find to be most interesting is how the pressure being applied to NASA and its contractors is centered on political purposes surrounding the 2020 election. a LOT of the Nation's problems in its exploration of space have come from political sources. But NASA's greatest accomplishment of landing on the Moon was a purely political one as well.

Maybe someday NASA will be given a budget free of politics, one legislatively defined as a certain percentage of the federal budget. Such a defined budget would really go along way in improving the timeliness and mission accomplishments of NASA.

Here's the latest on two active missions that exploring up close and personal different asteroids. It is pretty amazing what they are finding out and how they are doing so.

I am in awe of the pics from Bennu showing ROCKS being ejected from the surface of the asteroid

This view of asteroid Bennu ejecting particles from its surface on January 19 was created by combining two images taken on board NASA’s OSIRIS-REx spacecraft. Other image processing techniques were also applied, such as cropping and adjusting the brightness and contrast of each image.

This is absolutely incredible! And no one knows WHY this is happening, either. Maybe some of these  will eventually make their way to Earth as meteorites. Meteorites (Space Rocks) come from the asteroid belt, the Moon and Mars. Oh, and there are 60,000+ classified meteorites!

Chances are this magnificent bolide produced meteorites that fell into the Bering Sea.

The SpaceX Demo-1 mission has concluded with the successful splashdown of the Crew Drago spacecraft in the Atlantic Ocean at 8:45 a.m. EST.


This is a BIG step forward on returning astronauts to space using US built hardware launched from US soil.

I'll have much more tomorrow.
