ESA GW Space Mission

Hey Space Placers!

The European Space Agency (ESA) has announced that they will build a gravitational wave detection spacecraft.  2034 is the expected launch date - it is going to take awhile to build these 3 spacecraft.

Artist's Conception of Merging Black Holes
Such a mission would add a huge capability to humanity's ability to detect gravitational waves (GW). The 3 laser detectors would be MILLIONS of kilometers apart instead of just several as Earth based GW are.

With such a capability we might even be able to detect GWs from the Big Bang itself.

Elon Musk's Plans For Colonizing Mars

Hey Space Placers!

Read a paper that details Elon Musk's plans for Mars - and beyond.

It is a fascinating read and a hopeful plan for how humans will extend the species beyond Earth.

Musk rightfully describes the reasons why and provides some excellent hows as to getting humans to other places in the solar system.

Only time (and money spent) will tell if Musk and/or government space agencies are successful.

Congrats to the 2017 Astro Class

Hey Space Placers!

NASA announced its 12 newest astronaut candidates - culled from 18,300 applications! There are 5 women and 7 men, several doctors, pilots, a former Navy SEAL, scientists in a variety of fields and even a submariner. I say with unabashed Navy pride that the Navy rules in sheer numbers.

Here is their selfie which I love as it really captures their energy and camaraderie:

When I submitted my photo to the great folks at Earth & Sky, the editor Deborah Byrd, did some checking and found out some neat stuff. I had captured a rare lunar halo event

The funny part of this is that I had noticed a "regular" lunar halo earlier in the evening and took a pic with my iPhone and put it out on Twitter. But then I did my last look of the sky which I do every single night I noticed the unusual halo hanging low in the West. I went inside and got my camera and took a series of pics with different lenses. The rest is on the Internet ;-)

Moral of the story? always watch the sky and keep your camera handy!

Immune System Studies on the ISS

Hey Space Placers!

I have always maintained that getting  to Mars is more of a biological problem that a technical problem. What I mean by that is that the health and functioning of astronauts on a long space voyage to say, Mars, is going to take a toll on the crew. Radiation exposure, eyeball changes, muscle and bone loss, and changes to the immune system are all hazards astronauts face.

The International Space Station (ISS) is the ONLY bio-laboratory where we can study these conditions and determine solutions.

Watch this video for more information and here is the story.

New ESA Lunar Impact Project

Hey Space Placers!

My fave place in the Universe, the Moon, is getting a new project. The European Space Agency (ESA) has started a study to detect and measure the temperature of lunar impacts.  These impacts happen frequently and this study will help improve our knowledge of their frequency, size and resulting crater formation.

Date: 24 May 2017
Depicts: Lunar impact flash
Copyright: NELIOTA project

In 11 hours of observing time 4 impacts were recorded by the 1.2 meter (48 inches) telescope and its cameras. The large aperture of the telescope and the sensitivity of the cameras should allow for the gathering of a large amount of data

NASA also has an lunar impact monitoring program but uses 14-inch telescopes.

I would love to be able to see one of these impacts. Amateur astronomers are participating in the NASA project.

Event Horizon Telescope & Astronomy Month

Hey Space Placers!

from at sea aboard the ms Oosterdam in the Gulf of Mexico. 

A cosmic first got underway this week - humanity’s attempt to image a black hole using the Event Horizon Telescope (EHT)  . Using radio telescopes located around the globe to combine their separate signals into the equivalent of an Earth sized radio telescope antenna, the EHT will be making several observations.

Radio Telescopes like this one atop Mauna Kea, HI will be used worldwide
to obtain the 1st ever image of a black hole
Greg Redfern
EHT will try and image the supermassive black hole (SBH) located at the center of our Milky Way Galaxy known as Sagittarius A* (Sgr A*)       and the SBH located in nearby galaxy M87. EHT will also be observing several other galaxies.

SBHs are thought to be at the center of most galaxies. Sgr A* is over FOUR MILLION times as massive as our Sun and is 26,000 light years distant.  Due to intervening gas and dust we cannot see the center of our Milky Way Galaxy using optical telescopes but we can do so using radio telescopes.  EHT has been a decade long project that has now come to fruition with this history making observing run.

EHT will be collecting a huge amount of data during its 10 day observing run. The first several days have been going well and according to schedule. After the observing run is concluded EHT astronomers will then begin the arduous task of correlating and analyzing all of the data to try and achieve the first ever image of Sgr A*. It will take months of work before they know if they have been successful and publication of their results is expected in 2018. 

April is Global Astronomy Month (GAM)  , organized each April by Astronomers Without Borders (AWB)  ( It is the world’s largest annual global celebration of astronomy and brings new ideas and new opportunities. GAM 2017 is currently underway and is bringing enthusiasts together worldwide to celebrate Astronomers Without Borders’ motto “One People, One Sky”. You can find more information one events here .

Be sure to look at bright Jupiter in the southeast at sunset as it will be in the sky for several months. Venus has moved to the morning sky and is visible before dawn.

Hey Space Placers!

NASA's Cassini spacecraft is making preparations for its finale at the planet Saturn. This mission has written the book on the Saturnian system. The spacecraft is running on fumes and starting April 26 will begin its final phase - a 'Grand Finale' - eventually plunging into Saturn.

The September 15, 2017 death plunge into the atmosphere of Saturn is being done to protect the surrounding moons of Saturn, especially Enceladus, from any possible contamination. Enceladus has a warm ocean under all of its ice and is one of the prized places in the solar system to look for life.

New Horizons Spacecraft Update

Hey Space Placers!

The New Horizons spacecraft will be at the halfway point to its next target, 2014 MU69 this Friday. The spacecraft is traveling at 32,000 miles per hour and is 3.5 BILLION miles from Earth. Controllers will place New Horizons into hibernation on April 7th after being awake and operational for the past 2 1/2 years. The spacecraft will remain in hibernation for 157 days and upon reawakening will start to prepare for the flyby of 2014 MU69 that will occur on 1/1/19.

A KBO among the Stars: In preparation for the New Horizons flyby of 2014 MU69 on Jan. 1, 2019, the spacecraft’s Long Range Reconnaissance Imager (LORRI) took a series of 10-second exposures of the background star field near the location of its target Kuiper Belt object (KBO). This composite image is made from 45 of these 10-second exposures taken on Jan. 28, 2017. The yellow diamond marks the predicted location of MU69 on approach, but the KBO itself was too far from the spacecraft (544 million miles, or 877 million kilometers) even for LORRI’s telescopic “eye” to detect. New Horizons expects to start seeing MU69 with LORRI in September of 2018 – and the team will use these newly acquired images of the background field to help prepare for that search on approach.

August 21, 2017 Solar Eclipse Guide UPDATED

Hey Space Placers!

You are probably aware that there is a total solar eclipse occurring across the continental US on August 21, 2017. Millions of people will be able to see either a total or partial solar eclipse from wherever they are.

With just under 5 months to go now is the time to get ready for this event. Here is a COMPLETE guide to the eclipse courtesy of Sky and Telescope of which I am a long time subscriber as well as author.

The most important thing about the event is that you have to SAFELY observe the Sun. Be sure to read the safety guidelines.

This is part of S&T's Guide but I wanted to highlight it NASA has a Solar Eclipse Guide.

Surviving Lunar Night

Hey Space Placers!

The Moon is going to be a place where humanity will build outposts to stay long term; it is only a question of when.

One of the biggest issues to a lunar outpost is how to keep people and facilities warm when there is no sunlight. The Moon has day and night but it is on an almost month long cycle as opposed to our 24 hour cycle.

Temps can drop drastically during the lunar night and will need a heat source to keep people alive in their facilities.

The European Space Agency (ESA) is working on this problem and is looking to using lunar soil as a solution. 

It will be interesting to see how this research pans out.

Maunakea Observatories Photo Essay

Hey Space Placers!

On a tour arranged by Holland America's Westerdam I was able to return to the summit of Maunakea, Hawaii earlier this month to see the numerous observatories located there. It has changed quite a bit since my last visit in 1992.

Yesterday's blog included a picture of the VLBA radio telescope that is part of the Event Horizon Telescope. SO I won't include it here today.

The biggest change being that the 10-meter Keck Observatory now has a twin Observatory, Keck II. These are currently the largest optical telescopes in the world, having surpassed the 5-meter Hale Telescope at Palomar Observatory with the commencement of observations with Keck I in 1993.

Maunakea is a VERY special place because it has such clear and dry skies at almost 14,000 feet altitude. The telescopes there can observe above much of the Earth's atmosphere and enjoy excellent conditions. That is why there are so many telescopes there.

Collectively the Maunakea Observatories  are a very important asset in our study of the Universe. Here are some of the Observatories - refer to the link for more information about them.

Caltech Submillimeter Observatory
NASA Infrared Telescope Facility

Event Horizon Telescope (EHT)

Hey Space Placers!

Here is an excellent article on the Event Horizon Telescope (EHT)

EHT is supposed to start observations next month if all goes well but as the article states, it will be months of data processing before we know if the attempt to image a black hole event horizon was successful.

On my recent voyage I was able to get a photograph of the Hawaii-based radio telescope that is part of the EHT network. It was so cool to see this clone of the Very Large Array (VLA) that was featured in the movie 'Contact' and is poised to make history with EHT.

Hey Space Placers!

This is one of the most AMAZING pics I have ever seen:

It shows multiple images of a quasar 6 billion light years away that we can see due to the gravitational lensing of a foreground galaxy. A quasar is a galaxy that has an active supermassive black hole at its center. The black hole has infalling matter - planets, comets,  gas, etc - that heats up to millions of degrees as it gets consumed. It produces a great deal of light and energy that we can detect and study.

The gravitational lensing helps us to see this quasar and make measurements of the black hole.

See this video to help understand what you are seeing and read the article.

Back From Sea

Hey Space Placers!

Glad to be back after a wonderful 18 day Hawaii cruise aboard Holland America's beautiful Westerdam. I will share with you my trip to Mauna Kea Observatories later but I want you to see this first.

I toured the Hawaii Volcanoes National Park  HVNP on 2/24/17 and it is currently active in its central crater. It was amazing to see venting come out of the crater AND TO SMELL IT.
Kilauea Crater HVNP
Greg Redfern
When I was up at Mauna Kea you can see the VOG - volcanic smog - in a layer that flows through the valley between Mauna Kea and Mauna Loa.

Greg Redfern

The real treat was the next night transiting to our next port when we went directly south of HVNP. It looked like Hell on Earth as the Crater came alive in the dark.

I made a video of the lava flow that descends from the crater to the sea and posted it on You Tube. The awesome power of seeing new land being created right before your very eyes in such explosive fashion was breathtaking.

Lava Enters The Sea at Kamokuna, HI
Greg Redfern
I have seen the effects of lava on Earth and in the solar system but this was my 1st ever encounter with LIVE and active lava. It was simply amazing and humbling.

We humans think we are in control of all things - we are not. Earth is. Change the climate or the geology of our planet and you change humanity. We are seeing that in climate change right now and I have seen the affects in my world travels. I have personally witnessed the power of geology in the form of 8.1 and smaller earthquakes to include being in the San Fransisco event of October 1989.

And now, seeing the Dante's Inferno of destruction and creation at work at HVNP through the unrelenting power of lava, I am awed. Our planet and other bodies of the solar system have been built through mighty geologic forces including volcanoes and lava - the Moon, Venus, Mars, Io to name a few. We have even seen CRYOVOLCANOES - "lava" of frozen origin - at work in the outer solar system.

I hope this has given you a better perspective about the planet on which you live. The Earth doesn't need us, we need the Earth. Our planet has another couple billion years of evolution to undergo before the Sun destroys our planet by returning it into the dust from which it came 4.6 billion years ago.

Until then, lava will continue to create and destroy and amaze.

Orion-SLS Update

Hey Space Placers!

At sea again on my way to Hawaii.

There has been some very interesting reporting coming out that says that NASA is considering making the first Orion-Space Launch System (SLS) mission, Exploration Mission 1 (EM-1), a MANNED mission. The only other launch system in NASA’s history that had a crew onboard for the maiden flight was the Space Shuttle.

Orion-SLS has a crew abort system that can lift the Orion spacecraft with its crew to safety from the launch pad well into the ascent phase. The Space Shuttle had limited options for crew abort once the solid rocket boosters (SRBs) ignited and burned for two minutes. SLS will have two SRBs also.

There is also a move to name the EM-1 mission for the late Apollo 17 astronauts Gene Cernan. A fitting tribute to the last human to walk on the Moon.

Sky Guy Viewing ALERT!! Full Snow Moon Penumbral Eclipse Feb. 10-11

Hey Space Placers!

February’s Full Moon is called the Full Snow Moon as this is prime time for snow. The Full Snow Moon will look a little different this Friday as it will undergo a penumbral lunar eclipse.

There are three types of lunar eclipses - total, partial and penumbral   . All three occur when the Full Moon passes into the Earth’s shadow which is caused by light from the Sun. There are two components to our planet’s shadow  (and all shadows actually ) called the umbra and penumbra. The umbra is the central and darkest shadow zone which projects about a million miles into space while the penumbra is the outer and lighter shadow zone .      

Penumbral lunar eclipses are the least dramatic of the three types as usually there is only a slight shading. But for this penumbral eclipse the Full Snow Moon is deep within the penumbral shadow and misses the umbra by only 100 miles   . The result will be shading that will be visible on the Full Snow Moon similar to what you see in the picture I took of the penumbral phase of the October 8, 2014 total lunar eclipse.

The Full Snow Moon eclipse will look very similar to this picture taken of the eclipsed Moon on October 8, 2014.
Greg Redfern
To see the eclipse is easy if the sky is clear. Just go outside and face the east and find the Moon. Starting at 6:14 p.m. EST you should detect shading on the upper, or northern face of the Moon. By mid-eclipse at 7:44 p.m. EST the shading will be at its greatest and should be easily visible. The penumbral shadow will start to move off the Moon and the last vestiges of it should be seen around 9:14 p.m. EST.

The weather for Friday has clouds in the forecast but it is still worth checking to see if the Moon is visible. If clouds intervene you can watch the eclipse on the Internet  .

You may have heard about the close approach of a comet this weekend. Comet 45P/Honda-Mrkos-Pajdušáková or  Comet 45P for short    will pass a mere 7.4 million miles from Earth on February 11 at about 3 a.m. EST.

Comet 45P the closest comet we have had in more than 30 years, the last being the glorious Comet Hyakutake .  That was a COMET! I still remember being at Shenandoah National Park photographing it on the night of closest approach. With just your eyes you could see the long tail stretch across almost the whole sky - and it moved against the background stars as you watched! While watching that bright comet move silently and majestically across the sky it was easy to understand why our ancestors feared them.

Comet 45P is beyond naked eye visibility and even in binoculars or telescopes the brilliant full Snow Moon will make it hard to see. You can tune in to a live show on the Internet    after the Full Snow Moon eclipse.

By the way, you can see brilliant Venus in the southwest just after it gets dark with dim Mars just above it to the left. Jupiter makes its appearance in the southeast sky after 11 p.m. and Saturn rises in the hour before dawn in the southeast.

Hey Space Placers!

A very welcome read from Pope Francis on his views about the Big Bang and Evolution. Many do not know that the Vatican has its own observatory and staff to do research on cosmology and astrophysics.

Amazing Exoplanet Video

Hey Space Placers!

I was AMAZED to see this video that shows FOUR exoplanets in orbit around their star.

Let me say that again. We can actually SEE four other worlds outside of our solar system in orbit around another star.....WOW.

With new telescopes and instruments becoming available we will be seeing more and more of other worlds for ourselves.....unreal.

Two News Articles on NASA Under A Trump Administration

Hey Space Placers!

I will not comment on these stories as I never want to make this blog political. I do feel however an obligation to keep you informed on events that affect NASA and the space exploration community.

For full disclosure I know both of the authors and correspond with them.
