Chinese Space Station Open for Business

"The United Nations Office for Outer Space Affairs (UNOOSA) and the China Manned Space Agency (CMSA) have agreed to work together to develop the space capabilities of United Nations Member States via opportunities on-board China’s future space station...Under the agreements, UNOOSA and CMSA will work together to enable United Nations Member States, particularly developing countries, to conduct space experiments on-board China’s space station, as well as to provide flight opportunities for astronauts and payload engineers."

--Press statement by UNOOSA posted June 16, 2016. This will become more relevant as the United States and its partners start to wind down the International Space Station and end the program by 2024.

Fire Prevention in Space

This week NASA has set fire to a Cygnus space capsule after it departed from the International Space Station as part of its SAFFIRE mission (or Spacecraft Fire Experiment). The space agency hopes to learn more about fire safety in space.

Yes, 4,000 pounds of dirty laundry are burning in space. Okay, it's not the whole craft since more experiments will be conducted with the same spacecraft.

Speaking of the mission, David Urban, SAFFIRE’s principal investigator, stared:
In spacecraft, we’ve never had the opportunity to burn anything larger than approximately an index card…We really don’t know what the fate of a fire is. So our building of future spacecraft is based on one-G understanding and extrapolation of very small, short-duration experiments.
Better now as an experiment than later as an event.

Boarding the BEAM

Bigelow has posted a number of photos of its Bigelow Expandable Activity Module (BEAM), including an astronaut's entry of the module on the International Space Station last week. Take a look.
Picture Quote:  "NASA astronaut Jeff Williams successfully entered the BEAM, the first human rated expandable structure in space."

New Worlds and Irrational Thought

"...given what we now know about the number and orbital positions of the galaxy’s planets, the degree of pessimism required to doubt the existence, at some point in time, of an advanced extraterrestrial civilization borders on the irrational."

-- Statement by astrophysics professor Adam Frank in a New York Times article titled "Yes, There Have Been Aliens." He discussed the findings of a paper titled "A New Empirical Constraint on the Prevalence of Technological Species in the Universe," which uses the Drake equation to re-estimate the likelihood of intelligent alien life given what we have learned to date about exoplanets, concluding "...even if you grant that level of pessimism, a trillion civilizations still would have appeared over the course of cosmic history."

Juno Approaches Jupiter

I remember a lot more excitement about New Horizions approaching Pluto, yet the Juno mission to Jupiter is also an impressive feat.

On July 4th we will have another reason to look up into the sky and celebrate as Juno goes into orbit around Jupiter after a trip that lastest five years. Juno will orbit the planet for about 20 months. 

The goal of the mission is to
...understand the origin and evolution of Jupiter, look for solid planetary core, map magnetic field, measure water and ammonia in deep atmosphere, [and] observe auroras.
That's quite a list of duties and a good reason to stay connected to the mission. So remember to celebrate on the 4th.

Ukrainian Rockets in the US

Ukraine is proposing its rocket industry help replace the current Russian-built RD-180 rockets being used by the US space industry (much to the chagrin of Senator John McCain).

According to a TASS news story, Lyubomyr Sabadosh, head of Ukraine's State Space Agency of Ukraine (SSAU), recently stated:
We have proposes using our capabilities for implementing a joint design solution for the production of a liquid propellant engine, which is currently purchased in the Russian Federation. Our partners have an understanding that it's quite a complicated task, but we can cope with it, and the discussion will take place at the level of professional experts."
While the US has plans to build its own rocket engine, a deal with Ukraine gives us more breathing room while also helping a partner in the region looking for some help. One can only hope US officials give this proposal serious consideration.

Patience Pays Off: Student Discovers Planets

Michelle Kunimoto, a student at the University of British Columbia, recently discovered four new exoplanets about 3,200 light years away - one close to Mercury in size, two somewhat larger that the Earth, and a fourth closer in size to Neptune.  Ms. Kunimoto is a recent graduate from UBC where she obtained a Bachelor’s degree in physics and astronomy.

How did she do it?  A part of her research as a student, Ms. Kunimoto was studying data from the Kepler Space Telescope, which contained observations of about 150,000 stars. She noticed something odd with one of the stars but it has been missed because of the exoplanets long orbit - 637 days. While Kepler has found other exoplanets with longer orbits, it appears more planets such as these could be in the data for discovery.

In fact, it was this time last year that a high school student in England was credited with finding a Jupiter-sized exoplanet 1,000 light years away. He was looking at data collected by the Wide Angle Search for Planets (WASP) project at Keele University in England, which uses an approach similar to the Kepler Space Telescope.

So the data is out there. Now we simply need more industrious (and patient) students to sort through it.

Great Image: Cat's Eye

An endless variety of a images populate our night sky, such as the death of a star as shown here in the Cat's Eye Nebula. Just the idea of a halo 5 light years across is amazing, large enough to include both our Sun and Alpha Centauri. By the way, a variation on this image was cited in one of my earlier posts. 

Here is the explanation from NASA's Astronomy Picture of the Day: 
The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But the composite image combines many short and long exposures to also reveal an extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the left, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552.

Congress Ponders Travel to Alpha Centauri

SpacePolicyOnline has put together a summary of the latest NASA bill from the House Appropriations Committee covering FY 2017 funding priorities.  Some of the highlights include:
  • Rejection of the White House's plan to capture an asteroid and instead a new focus on a manned mission to the Moon;
  • Continued support for a robotic mission to Europa;
  • Continued support for the SLS and Orion spacecraft; and
  • Support for a 2069 mission to Alpha Centauri using propulsion that is 1/10th the speed of light.
I had not heard of the Alpha Centauri mission earlier.  Here is the language from the committee report:

The Committee encourages NASA to study and develop propulsion concepts that could enable an interstellar scientific probe with the capability of achieving a cruise velocity of 0.1c. These efforts shall be centered on enabling such a mission to Alpha Centauri, which can be launched by the one-hundredth anniversary, 2069, of the Apollo 11 moon landing. Propulsion concepts may include, but are not limited to fusion-based implementations (including antimatter-catalyzed fusion and the Bussard interstellar ramjet); matter-antimatter annihilation reactions; multiple forms of beamed energy approaches; and immense ‘sails’ that intercept solar photons or the solar wind. At the present time, none of these are beyond technology readiness level (TRL) 1 or 2. The NASA Innovative Advanced Concepts (NIAC) program is currently funding concept studies of directed energy propulsion for wafer-sized spacecraft that in principle could achieve velocities exceeding 0.1c and an electric sail that intercepts solar wind protons. Over the past few years NIAC has also funded mission-level concept studies of two fusion-based propulsion concepts. Therefore, within one year of enactment of this Act, NASA shall submit an interstellar propulsion technology assessment report with a draft conceptual roadmap, which may include an overview of potential advance propulsion concepts for such an interstellar mission, including technical challenges, technology readiness level assessments, risks, and potential near-term milestones and funding requirements.
It is odd that we are going back to the Moon while also planning for travel to another star.  Yet the Moon is seen as a better way to get us to Mars.  Here is the committee report on that point:

...the Committee believes that neither a robotic nor a crewed mission to an asteroid appreciably contribute to the over-arching mission to Mars. Further, the long-term costs of launching a robotic craft to the asteroid, followed by a crewed mission, are unknown and will divert scarce resources away from developing technology and equipment  necessary for missions to Mars, namely deep space habitats, accessing and utilizing space resources, and developing entry, descent, landing, and ascent technologies.
Toward that end, no funds are included in this bill for NASA to continue planning efforts to conduct either robotic or crewed missions to an asteroid. Instead, NASA is encouraged to develop plans to return to the Moon to test capabilities that will be needed for Mars, including habitation modules, lunar prospecting, and landing and ascent vehicles. Further, the Committee is supportive of NASA’s efforts to use the International Space Station (ISS) to conduct research necessary to enable long-term human spaceflight, or ‘‘Earth-reliant’’ technology development; cis-lunar space activities, or ‘‘proving ground’’ efforts such as Orion flights on SLS in the vicinity of the Moon, and deployment and testing of deep space habitation modules; and finally, NASA’s ‘‘Earth independent’’ activities which include using cis-lunar space as a staging area, mapping potential human exploration zones and caching samples on Mars as part of the Mars Rover 2020 mission.
It makes sense to me.  Returning to the Moon may not excite some out there, yet if we sell it as a testing ground for Mars it may gain greater support.  We may be joining the Chinese and Russians on the surface as well, but if it takes a space race to get us to the Moon and Mars then so be it.

Early Report: BEAM Not Inflating

This week NASA started to inflate the Bigelow Expandable Activity Module (BEAM) while attached to the International Space Station. It should have looked like the image above, but early reports indicate the pressurization has not gone well.

NASA has a press conference at noon ET today to discuss the status of BEAM.  We shall learn more, yet I am not surprised with a few glitches at the start of a new approach to space habitation. Overall, I expect Bigelow's habitat will be a solid addition to the space program. 

Update:  Per NASA:
NASA and Bigelow Aerospace will make a second attempt at 9 a.m. EDT Saturday, May 28, to expand the Bigelow Expandable Activity Module (BEAM), currently attached to the International Space Station. NASA Television coverage will begin at 8:45 a.m.
Second Update:  All is well. Yesterday the BEAM successfully inflated (as shows below).  Engineers believe the 15 months of storage may have made the pressurization process more difficult.

India Tests its Space Shuttle


Who knew India had a space shuttle (shown above). Actually, it is a prototype of a reusable launch vehicle that should lead to greater things. The first flight on Monday lasted only 13 minutes.

Indian Prime Minister Narendra Modi tweeted his pleasure at the successful flight earlier this week:
Launch of India's first indigenous space shuttle RLV-TD is the result of the industrious efforts of our scientists. Congrats to them.
This could help India increase its share of the space transportation industry, giving SpaceX and others some real competition.

Star Trek Returns in Many Forms

If you are awaiting the new Star Trek series on CBS, you may enjoy this new clip setting the stage for the series' release in 2017.  It does not reveal any characters or plot lines, but it does promise new crews, new villains, new heroes, and new worlds.  What else can you ask for?

Of course, you can ask for more information on the next Star Trek film, Star Trek Beyond, and this trailer provides that as well.  As always, the scenes will keep you on the edge of your seat.  Better yet, you will only need to wait until July 22 for the film. 

NYT's APP: A Trip to Pluto

The New York Times has released a 3D video for smartphones called "Seeking Pluto's Frigid Heart" that takes you on a trip to Pluto via New Horizons.  It's a gripping tour specifically designed for a mobile device since you need to turn your entire body to take in everything around you, including the distant Sun, Charon on the horizon, and even the dwarf planet's surface as you observe craters and icy plains. 

The New York Times created the app with the Lunar and Planetary Institute and the Universities Space Research Association. The 3D video debuted at the 2016 Tribeca Film Festival, which featured18 virtual reality movies.

You can also watch the video on your desktop, but it does not have the same effect and lacks the clarity of the app.  I recommend you download the app and enjoy the tour.

Portrait of Mars

The Hubble Space Telescope is useful for "family" shots in our own solar system, as this new image taken May 12th demonstrates.

Here is the rest from NASA:
The large, dark region at far right is Syrtis Major Planitia, one of the first features identified on the surface of the planet by seventeenth-century observers. Christiaan Huygens used this feature to measure the rotation rate of Mars. (A Martian day is about 24 hours and 37 minutes.) Today we know that Syrtis Major is an ancient, inactive shield volcano. Late-afternoon clouds surround its summit in this view.
A large oval feature to the south of Syrtis Major is the bright Hellas Planitia basin. About 1,100 miles across and nearly five miles deep, it was formed about 3.5 billion years ago by an asteroid impact. 
The orange area in the center of the image is Arabia Terra, a vast upland region in northern Mars that covers about 2,800 miles. The landscape is densely cratered and heavily eroded, indicating that it could be among the oldest terrains on the planet. Dried river canyons (too small to be seen here) wind through the region and empty into the large northern lowlands. 
South of Arabia Terra, running east to west along the equator, are the long dark features known as Sinus Sabaeus (to the east) and Sinus Meridiani (to the west). These darker regions are covered by dark bedrock and fine-grained sand deposits ground down from ancient lava flows and other volcanic features. These sand grains are coarser and less reflective than the fine dust that gives the brighter regions of Mars their ruddy appearance. Early Mars watchers first mapped these regions. 
An extended blanket of clouds can be seen over the southern polar cap. The icy northern polar cap has receded to a comparatively small size because it is now late summer in the northern hemisphere. Hubble photographed a wispy afternoon lateral cloud extending for at least 1,000 miles at mid-northern latitudes. Early morning clouds and haze extend along the western limb.

Great Image: Double Transit of the Sun

The transit of Mercury across the sun was interesting to watch last week, as is the transit of the International Space Station. In fact, both transits are shown in the image above. 

Here is the full story from APOD:
This sharp video frame composite was taken from a well-chosen location in Philadelphia, USA. It follows the space station, moving from upper right to lower left, as it crossed the Sun's disk in 0.6 seconds. Mercury too is included as the small, round, almost stationary silhouette just below center. In apparent size, the International Space Station looms larger from low Earth orbit, about 450 kilometers from Philadelphia. Mercury was about 84 million kilometers away.

Hillary and UFOs

I am not sure how many votes it will get her, but Hillary Clinton has given UFO enthusiasts her pledge to be more transparent with government data on such events.

In an interview, Clinton stated,
There are enough stories out there that I don’t think everybody is just sitting in their kitchen, making them up.
I remember Newt Gingrich discussing moon colonies during his presidential bid and all he got was a few chuckles. I don't expect Clinton will gain more than that. 

What I would like is full-throated support for a Martian mission. That might excite more Americans and move us beyond tax records, speech transcripts, hand size, and other topics that only frustrate the electorate. We need something hopeful for our future.

Saving Earth


"The challenge of colonising Mars shares remarkable DNA with the challenges we face here on Earth. Living on Mars will require mastery of recycling matter and water, producing food from barren and arid soil, generating carbon-free nuclear and solar energy, building advanced batteries and materials, and extracting and storing carbon from atmospheric carbon dioxide – and doing it all at once."

--Science writer Joe Mascaro in an Aon article titled "To Save Earth, Go To Mars."

Exoplanets: The Count Increases

NASA announced this week that scientists analyzing 2015 data from the refurbished Kepler space telescope, now called K2, has discovered another 1,284 exoplanets. This doubles the number of planets discover by the telescope since it was put into operation.

Among these newly discovered exoplanets, 550 are rocky like Earth and 9 are within their sun's habitable zone. As a result, the Kepler mission has discovered a total of 21 exoplanets that appear to be similar to Earth.

This is goods news as K2 continues its mission while other space telescope missions are being planned to help with the search in the near future.

Mercury's Transit of the Sun

Don't go blind today trying to watch Mercury transit the Sun because it cannot be seen with the naked eye anyway. NASA has it covered with a live video here. The transit will started at 7:15 EST and last a little over seven hours. This event happens only 13 times a century and scientists are using it to study Meecury's exo-atmosphere. Yes, as with exoplanets, such transits in front of a sun are very informative.

The Search for Habitable Planets Expands

It is amazing that Star Trek in the 1960s and Cosmos on the 1970s speculated about distant planets, and here we are today actually studying thousands of newly discovered planets, searching for moons around these planets, and even planning to analyze the atmospheres on the planets themselves. We may not have flying cars as promised, but we are starting to see those distant worlds we predicted which I believe is far more fascinating.

Last month, NPR had a story on the search for moons around approximately 1,000 distant planets by astronomer David Kipping at Columbia University. He believes gaseous planets similar to Jupiter and Saturn may have habitable moons where life is possible. We know our solar system has such moons, such as Europa and Enceladus, that we have yet to adequately explore for signs of life. So we have plenty of work to do here at home as well. 

Another NPR story this month discussed three nearby planets that circle a red star. Only 40 light years away, the Earth-size planets may offer a habitable environment for life. And using the Hubble Space Telescope, astronomers hope to be able to learn about the atmospheres of these planets as sunlight filters though them, while the upcoming James Webb Space Telescope will be able to provide details on the chemical composition of the atmosphere. More reasons to be excited about new space investments.

The search can only get more interesting as our technology improves and our curiosity grows. Whether in our solar system or far beyond, there is so much to study and understand.

SpaceX Aims for Mars

It wasn't too long ago NASA stated it would leave Low Earth Orbit (LEO) missions for the private sector while the space agency would take on the bigger tasks off Earth.

I guess Elon Musk never received the memo because he is gunning for Mars (while also doing quite well with LEO having just won a USAF contract).

Here are a few messages about his new Dragon 2 capsule, also labeled the Red Dragon, that he hopes to land on Mars in 2018.
 
 
Planning to send Dragon to Mars as soon as 2018. Red Dragons will inform overall Mars architecture, details to come 
Dragon 2 is designed to be able to land anywhere in the solar system. Red Dragon Mars mission is the first test flight.
I don't want to be someone who bets against Mr. Musk and I hope can make it happen as the race for the Red Planet continues. Unfortunately, it seems the Europeans and Russians are delaying their ExoMars mission until 2020, so the field is open for SpaceX yet the path is still perilous.

Understanding Pluto's Neighbors

Later this month Chicago's Adler Planetarium will be premiering its new show Planet Nine. The program will discuss the New Horizons mission to Pluto, the dwarf planet's neighbors, and the search for Planet Nine (though I still argue Pluto should remain the ninth planet).

And in case you would like to read a little more on some of the other dwarf planets in the show (including the one that cost Pluto its place among planets), here is what the Adler Planetarium shared on its website:

Eris
The discovery of Eris prompted the International Astronomical Union to agree on an official definition of “planet” in 2006. Eris is almost exactly the same size as Pluto, yet it weighs 25 percent more. It is also remarkably bright, reflecting 97 percent of the light it receives from the Sun. To put that in perspective, the Moon reflects just 12 percent of the Sun’s rays.
Haumea
Shaped like a football, Haumea rotates incredibly fast—once every four hours! This object’s fast rotation causes its unusual shape. Were it rotating more slowly, gravity would pull it into a sphere, which is why it qualifies as a dwarf planet even though it isn’t round.
Sedna
Sedna’s orbit takes it deep into the far reaches of the Solar System, almost 20 times as far as Pluto ever goes. A year on Sedna is 11,400 times as long as a year on Earth! But perhaps the most interesting thing about Sedna is the hints it gives us that there are many more objects yet to be found at the edges of our cosmic backyard.
In the meantime, here is a video sharing more about the proposed Planet Nine from Astronomer Konstantin Batygi.

A Beautiful Planet - Blue Planet Part II

You may remember the IMAX film Blue Planet from 1990.  It was an fascinating adventure with views of the Earth from the NASA space shuttle missions.  It also provided plenty of warnings about what we needed to do to protect the planet. 

The latest IMAX film A Beautiful Planet is more or less an update of that earlier film 26 years later, but this time focusing on views from the International Space Station (which was a good choice since we now lack a space shuttle program). 

The IMAX film premiered yesterday and can be seen across the nation at IMAX theaters.

The Martian: Art May Create Reality


"When I saw the U.S. film 'The Martian', which envisages China-U.S. cooperation on a Mars rescue mission under emergency circumstances, it shows that our U.S. counterparts very much hope to cooperate with us."

--Comments by Xu Dazhe, the chief of the China National Space Administration, quoted in a Reuters article

NASA Was Worried About Crew Morale

A Slate story discussing women in space shared this earlier perspective from a 1970s NASA paper:
It is possible that woman, qualified from a scientific viewpoint, might be persuaded to donate her time and energies for the sake of improving crew morale. 
I am glad they threw in that "scientific viewpoint" so this astronaut could understand her crewmates in various ways.

The article is about how the space agency is coming to terms with "female needs," which seemed to be the lesser concern years ago. You can read about fears of "menstrual disturbances" and more.

I hope no one brings this up at a committee hearing. I really do not want to hear a male Senator try to wrap his head around the issue. The next thing you know we will be discussing separate bathrooms on the space station. 

Note: In case you are wondering, everyone uses the same toilet on the space station. The toilet below is on the Zvezda Service Module.

Amazing Views of Planet Earth

It is worth looking back down once in awhile on this big blue marble called Earth. We are searching the heavens to find what we already have - an amazing planet that can meet all of our needs if we can learn how to live within its limits.

This NASA video taken from the International Space Station shows a surface that is stunningly beautiful. As Carl Sagan has said, 
The beauty of a living thing is not the atoms that go into it, but the way those atoms are put together.
The arrangement of atoms on our home planet never fails to cause awe and wonder.

Spuds on Mars

Maybe Matt Damon's character in The Martian was on to something. NASA is looking into growing potatoes on the Martian surface.  Fortunately, Peru can offer about about 4,500 varieties, so it is possible the perfect match can be found.  Maybe we will get a Red Planet potato for use both on-world and off-world.

In a Wall Street Journal interview, NASA planetary scientist Chris McKay stated, “I think we’ll be able to find varieties of potatoes that will grow at cold and low-pressure conditions. That would be interesting to know for Mars applications.”  

And when he says cold he means it - averaging minus 84 degrees Fahrenheit, with lows going to minus 284 degrees. Add to that high amounts of radiation and you have created a difficult scenario for any garden. 

Potato tests in Peru will help to determine the strongest varieties for possible replanting on Mars. Hopefully, this region in the New World can be the springboard for expanding life on another planet. 

All of this good news in that we have moved past "Will we go to Mars?" and on to "How will we live on Mars?"

A $600 Million Ride to the Moon?

The Russians made an offer sometime back to Amazon CEO Jeff Bezos to see how much he wanted to go to the moon - $200 million to circle the moon in a Soyuz spacecraft. When Mr. Bezos said he wanted Russia to test the mission first, the Russians agreed for another $400 million. I guess anything is possible with a few dollars on your pocket.

Of course, Mr. Bezos said no and now he hopes to create new space tourists via his company Blue Origin at a much lower costs. I think this is a much better way to spend his funds.

You can read the full story at Space.com.

Siri Goes to Alpha Centauri

Talk is growing concerning sending robotic missions to other planets, in this case the planets in the Alpha Centauri system.  That's right, a mission of many tiny, light-propelled spacecraft traveling at 20 percent the speed of light would leave our solar system to explore the great beyond.  Each little "probe" would cost about the same as an iPhone.  And this proposed voyage to our closest neighboring star system would take only 20 years.

The project is called "Breakthrough Starshot" and it involves space financier Yuri Milner (of the earlier "Breakthrough Listen"), cosmologist Stephen Hawking, and Facebook's Mark Zuckerberg. This is quite a cast of characters sure to encourage more interest and funding.

Here is what they are proposing:
...with current rocket propulsion technology, it would take tens or hundreds of millennia to reach our neighboring star system, Alpha Centauri. The stars, it seems, have set strict bounds on human destiny. Until now.

In the last decade and a half, rapid technological advances have opened up the possibility of light-powered space travel at a significant fraction of light speed. This involves a ground-based light beamer pushing ultra-light nanocrafts – miniature space probes attached to lightsails – to speeds of up to 100 million miles an hour. Such a system would allow a flyby mission to reach Alpha Centauri in just over 20 years from launch, and beam home images of possible planets, as well as other scientific data such as analysis of magnetic fields.

Breakthrough Starshot aims to demonstrate proof of concept for ultra-fast light-driven nanocrafts, and lay the foundations for a first launch to Alpha Centauri within the next generation. Along the way, the project could generate important supplementary benefits to astronomy, including solar system exploration and detection of Earth-crossing asteroids.
Of course, the challenges facing such a mission are enormous, and the initiative has a long list of topics that need to be resolved first, such as battery design, light sail strength, the risks of interstallar dusk, focusing light beams, communication over great distances, and more.  In other words, this mission will not take off tomorrow.  But the $100 million contribution from Mr. Milner will certainly help to get things started.

Trial runs in our own solar system are part of the planning stages.  For instance, we could send a small spacecraft to Pluto in about 3 days rather than 9 years.  So even without reaching distant planets, this project could transform how we study our own solar system.

Great Image: Close Up of the Milky Way

The image above is one of 700 stitched together to show us the Milky Way galaxy in its full beauty as viewed from Earth's Southern Hemisphere.  These images were taken by the APEX telescope in Chile’s Atacama Desert. National Geographic reports it took about 3 years to collect all of these images.  You can also scroll through the entire set of images at the National Geographic link.  An impressive feat!

Flawless Blue Origin Rocket Landing

With all the recent praise of SpaceX's successful landing of its Falcon 9 reusable rocket, let's not forget that Blue Origin also had a successful landing of its New Shepard reusable rocket recently as well. Blue Origin CEO Bezos said it best in this Tweet:
Flawless BE-3 restart and perfect booster landing.  CC chutes deployed. @BlueOrigin
--Jeff Bezos (@JeffBezos) April 2, 2016
 You can watch the landing in this clip from Blue Origin.

A Whole New Trajectory for Weapons of War

I have heard of beating swords into ploughshares, but converting intercontinental missiles into space rockets?  That is a new one, but I like the idea.

Orbital ATK Vice President Barron Beneski has proposed using decommissioned intercontinental ballistic missiles (such as the Peacekeeper above) for new purposes.  It makes a lot of sense, particularly for a company that lacks its own rockets.  Orbital ATK was using old Soviet-era rockets until one exploded.  Now its Cygnus cargo ship resupplying the International Space Station is hooking a ride on competitor rockets. 

Of course, no good idea goes unopposed, and Virgin Galactic is trying to spike this idea because Orbital ATK may become a competitor. 

This is the other side of private sector space competition - everyone wants to have the best rocket and not really share the profits.  Left to itself, we will be back to the huge space companies with few new ideas.  I think the decommissioning idea is a good one - reuse old rockets for space purposes and allow the Air Force to unload some inventory that is expensive to maintain.  And these rockets can be sold to any party, not just Orbital ATK, to maintain a level playing field.

SpaceX: Success!

SpaceX has done it!  Earlier today the space company's Falcon 9 rocket successfully landed on a drone platform off the coast of Florida following a successful launch of a Dragon cargo ship towards the International Space Station. Long-awaited good news for all. 

President Obama was also impressed, tweeting:
Congrats SpaceX on landing a rocket at sea. It's because of innovators like you & NASA that America continues to lead in space exploration.
Update:  The Dragon cargo ship safely arrived at the International Space Station yesterday (April 10th).  One of the items delivered is BEAM, or the Bigelow Expandable Activity Module, which will serve as inflatable space habitat attached to the station.

Han Solo Wasn't So Tough


A piece by Kenneth Chang in the New York Times recently noted the asteroids in our asteroid belt would be nothing like what you saw the Millennium Falcon navigate in Star Wars: The Empire Strikes Back. Wait, George Lucas misled us?

In his entertaining and informative article, Mr. Chang produces a few figures on the asteroid belt between Mars and Jupiter, and then adds this: 
 S. Alan Stern, the principal investigator for the New Horizons mission to Pluto wrote that when his spacecraft passed through the asteroid belt in 2006, the chance of collision was “almost vanishingly small — far less than one in one billion.”
So, Lucas was exaggerating, and our spacecraft heading to the outer planets were never in jeopardy.  I feel much better.  But what about that asteroid monster?

International Space Station Traffic Jam

Things are getting busy up there in low Earth orbit.  The other week Orbital ATK sent up a Cygnus cargoship.  And then Russian resupply ship Progress 63 (animation shown above) was launched from the Baikonur Cosmodrome in Kazakhstan on March 31st.  Progress 61 had to undock and depart to make way for Progress 63. 

And now SpaceX is preparing for another Dragon resupply run on April 8th with a crew of mice to see how their little bodies handle space.  The mice will later be dissected and sent back to Earth for further study.  Scott Kelly did a little better than that with his mission. 

It is nice to see this complex interchange becoming so routine with the private sector playing a growing role.  A good sign for future cooperation and space projects.

Quotable: Was Galileo Overrated?

"...he was not the only telescopic astronomical observer at the time, and all the discoveries he made were made independently and contemporaneously by others in Britain, Germany, even Italy. This point is hard to reconcile with the modern myth because even if Galileo had never used a telescope, it would not have changed anything in the history of astronomy."

-From an article by Thony Christie in his Aeon article titled "Galileo’s Reputation is More Hyperbole Than Truth."
