I’m back from my own personal August recess and catching up on almost a month of space news. Here’s your headline dump for August 14 to September 9! A lot has happened

Down to Earth

The Trump Administration has named Oklahoma Congressman Jim Bridenstine as their nominee for NASA administrator.

The Chinese and European astronauts conducted a joint survival training exercise off the coast of China.

Sierra Nevada Corporation conducted a “captive carry” flight of their Dream Chaser spaceplane.

Last week an ESA Ariane 5 rocket had a pad abort. The agency is still investigating.

In Orbit

The Dragon capsule launched two days earlier docked with the ISS on August 16th.

The day after the cargo. arrival, cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy conducted a successful spacewalk to do space station maintenance as well as some small satellites deployments.

Then on September 3rd a Soyuz returned to Earth, safely carrying Jack Fischer, Peggy Whitson, and Fyodor Yurchikhin to the steppes of Kazakhstan. Both Yurchikhin and Whitson now have accumulated over 600 days in space.

Meanwhile on the ground, a dedicated team of flight controllers was riding out Hurricane Harvey in Houston’s Mission Control Center to ensure the successful undocking and return of the crew.

Speaking of hurricanes, the ISS crew has taken some incredible imagery of Irma has it makes its way across the Caribbean and now Florida.

Lots of launches while I was out. Here’s a worldwide rundown:

Around the Solar System

Congratulations to the engineers and scientists on the New Horizons project; the International Astronomical Union has selected many of their original choices for features on Pluto as official names!

Good news for Mars enthusiasts: there is new talk at NASA of planning a robotic Mars sample return mission for the middle of the 2020s.

Down to Earth

Orbital ATK performed a qualification test firing of the abort motor for the Orion spacecraft.

A recent study at the University of Nevada – Las Vegas (UNLV) found that the cancer risk for a journey to Mars may be higher than previously thought. Spaceflight Insider published a response opinion piece by Robert Zubrin (author of The Case for Mars).

Jeffrey Kluger (science editor at time and coauthor with Jim Lovell of Apollo 13) has published a new book Apollo 8 about humanity’s first mission to orbit the moon. I am currently listening to the book on Audible and will publish a review next week.

A private company based in Europe called Bake In Space has announced plans to fly an experimental zero-gravity oven and dough recipe to the space station.

In Orbit

There have been two orbital rocket launches in the last week:

The Progress freighter arrived at ISS this past Friday and docked successfully, delivering supplies from station propellant to food, water, and science experiments.

Tragically, an employee of the Russian space program died after he was deployed to the cleanup zone after the Soyuz launch and a fire engulfed his truck.

The Chinese space agency has tested robotic refueling with their uncrewed Tianzhou freighter at the Tiangong-2 space station.

Ever since the SpaceX Dragon capsule docked to the ISS last week, robotics engineers have been busy at work unloading new science experiments, including the NICER neutron star observatory and the Roll Out Solar Array (ROSA).

Out There

Astronomers continue to search for habitable, Earth-like planets around other stars. However, other oddball planets also continue to pop up, like KELT-9b, which is the hottest planet ever discovered.

Down to Earth

Gennady Padalka, who holds the record for most days in space by any person ever, is retiring from the Russian space program.

Back home at NASA, Anna Fisher, hired in the first class of space shuttle astronauts in 1978, has retired from the agency.

It was a busy week with some important milestones across NASA. Some of the key events are summed up well by this quick video:

In Orbit

Peggy Whitson made history by breaking fellow astronaut Jeff Williams for most accumulated days in space for any NASA astronaut. Whitson is at 538 days and counting. She will be the most experience active astronaut or cosmonaut by far when she gets home, now that Padalka has retired. Here is video of the president’s live phone call to congratulate Whitson:

Three rocket launches since my post last week:

  • April 18 – an Atlas V rocket launched from Florida carrying a Cygnus cargo resupply to the ISS
  • April 20 – a Soyuz rocket launched from Kazakhstan carrying NASA astronaut Jack Fischer and Russian Cosmonaut Fyodor Yurchikhin to the ISS
  • April 20 – a Chinese Long March 7 rocket launched from the Hainan Island spaceport carrying an unmanned Tianzhou resupply craft headed for the Chinese space station

Both the Cygnus cargo freighter and the Soyuz crew arrived at ISS with no problems. The Chinese Tiangong also successfully docked with the Tiangong space station (which is currently unmaneed).

Cygnus in flight below ISS

Today, April 30th, SpaceX attempted to launch another Falcon 9 rocket from Florida, carrying a payload for the US National Reconnaissance Office. The launch was scrubbed during the last minute before ignition due to an issue with the booster. SpaceX will try again tomorrow.

Around the Solar System

NASA’s Dawn spacecraft, in orbit of asteroid Ceres, has lost another reaction control wheel, and is now flying on its remaining wheel. The spacecraft launched in 2007. Mission managers believe the spacecraft should make it through the remainder of the mission on the last of four wheels.

NASA’s Cassini spacecraft, in orbit of Saturn, is wrapping up operations as it heads toward the end of its mission in September. The mission is going out in style, with several new images from its new closer orbit. Including this view of Earth through Saturn’s rings and these images from the closest ever orbit of Saturn.

2016 In Review – Part I

2015 year in review posts: Part I and Part II.

2014 year in review posts: Part I and Part II.

2013 year in review posts: Part I and Part II.

Part I – Exploration

Spaceflight, as a many-hundred billion-dollar sector, is a broad and complex industry. Even if we focus in on “exploration” – which is the primary focus of this blog – so that we can ignore military and commercial uses of Earth orbit, we are still left with a global list of activities, studies, missions, and companies. This means there is a lot of stuff going on. 2016 was a busy year with many exciting missions from several different countries. This diversity is great, but makes it hard to boil down the events of last year into a coherent story. Even within NASA, we have the ISS program, with its own highs and lows, and the totally separate and just as successful planetary science portfolio of missions. Those missions keep on going, regardless of whether the most recent cargo delivery has made it to our astronauts in orbit, for instance. Meanwhile, in China, the CNSA is continuing to grow as a nascent space power with new rockets, new launch sites, and a brand new space station. Then there’s Russia, Japan, Europe, India, and more. If any theme can be found at all in the events of last year it is that space exploration continues to be a diverse and global endeavor. Putting any nationalism aside, this should give us hope that despite the ups and downs of the economies or space budgets in any given country, that exciting times lie ahead.

It’s hard to start a summary of 2016 in spaceflight without acknowledging that the United States had a major election, with a new President to be inaugurated this week. Any presidential transition leads to uncertainty in the future of government programs, including NASA. Often election years leave the federal government in a continuing resolution. A continuing resolution means that Congress has yet to pass a budget for the year. This leaves NASA and other agencies working under last year’s budget levels, with no increase for inflation or otherwise. The election was a big story for the country in a lot of ways, but NASA and its programs are most likely to feel the effects in 2017, as it tries to continue with business as usual as it waits for new priorities and a new budget.

While 2017 may bring about change (or not), 2016 was another good year for NASA’s flagship space exploration missions. NASA had no major failures last year, just the usual hiccups and challenges (space is hard, after all) and even launched a new planetary exploration mission: OSIRIS-REX, which is on its way to visit an asteroid in 2023. In fact, last year showed that NASA is still a clear leader in planetary exploration, with probes in action all over the solar system. The NASA fleet at Mars remains strong, with two rovers on the surface and two probes in orbit. New Horizons received a mission extension and is on its way to a Kuiper Belt Object rendezvous in a few years. Meanwhile, the probe Juno made orbit at Jupiter and started scientific observations. Unfortunately, Juno has some sticky propellant valves and missed some of its early science orbits when it entered “safe mode.” Fortunately, the probe was brought out of safe mode and completed a Jupiter flyby in December. Most of the probe’s 20-month mission is ahead. Hopefully Juno’s worst days are in the past! Out at Saturn, NASA is still operating the Cassini probe, which has been in orbit since 2004. Sadly, 2017 will see the end of Cassini, as it destroys itself in dramatic fashion, with a dive into Saturn’s atmosphere.

Two other planetary missions of note from other countries had some action last year. ExoMars (a joint mission between ESA and Russia) launched and made it to Mars. However, its companion lander, Schiaparelli, was unable to make it safely to the Martian surface and crash-landed. Thus, NASA remains the sole space agency to have safely brought a spacecraft to the surface of Mars… having done so seven times. Of course, we shouldn’t forget that the Soviet Union is the only country to have ever landed a probe on Venus! A feat which has not been repeated since 1982, and does not appear to be repeated any time soon, as most space agencies focus on asteroids and the outer solar system in their planetary science missions. Venus is not forgotten though, as Japan was able to begin doing science with their Akatsuki orbiter at Venus last year.

Following the theme of “space is hard,” Japan had a pretty devastating failure when their new X-ray telescope Astro-H, or Hitomi, went out of contact after reaching orbit. Fortunately, Japan already has a strong space program and seems mature and professional enough to learn from their mistakes – they released a failure report very quickly after the accident. They currently have an asteroid sample return mission, Hayabusa 2, en route to its target in 2018, which we should all be very excited about. NASA has a strong relationship with JAXA, and will be curating the Hayabusa samples here at the Johnson Space Center when they return.

In human space exploration, the story continues to be the International Space Station. The ISS had an exciting year, partly because NASA and ESA continue to send charismatic astronauts who manage to make the mission feel very personal to all of us following back on Earth. It was a great year for following astronauts on Twitter, including Jeff Williams, Kate Rubins, Tim Kopra, Tim Peake, Scott Kelly, Shane Kimbrough, Thomas Pesquet, and Peggy Whitson. It’s hard to see how this trend will do anything but accelerate, as it’s a cheap and easy way for NASA to connect with the American public and share its mission. Scott Kelly of course returned from space early in the year and retired from NASA on a high note. Since the “year in space” was such a success, both operationally and as a public affairs bonanza, it seems likely NASA will want to try more longer duration expeditions in the future.

On the more nuts and bolts side of things for the ISS, all major mission events went well last year, with both the arrival and installation of the new IDA2 docking adapter and the Bigelow Expandable Activity Module (BEAM). BEAM is an exciting demonstration of where human habitability in Earth orbit may be able to go in the future with inflatable structures. It is exciting to think that the technology may spinoff a private-public partnership with either or both of the companies Bigelow and Axiom to expand the ISS with new large inflatable modules in the future.

The ISS did face some minor setbacks of its own, although not quite as dramatic as in more recent years. Two rocket failures impacted ISS logistics: the SpaceX explosion on the pad in Florida in September and the loss of a Russian Progress resupply mission in December. The good news for NASA was that the SpaceX failure was not an ISS mission, but it meant a delay to the next planned resupply flight of a Dragon capsule, now scheduled for February. ISS is well stocked on supplies thanks to a Japanese resupply mission that also flew in December and the Orbital ATK Antares rocket returning to flight status in October. Even with both Japanese and American rockets able to keep ISS supplied, having the Russian Soyuz rocket family grounded must always make mission managers uneasy. After all, it is the same rocket family that failed in December that also delivers crews to the station. We are not in uncharted territory, as expedition schedules were in limbo after similar accidents in 2011 and 2015. But the ups and downs of the launch vehicle sector are a continual challenge not only for NASA’s ISS program but for dreamers who envision hundreds of people at a time into deep space for colonization. ISS truly is the foothold where we must learn first, and is a great proving ground for those dreamers.

The ISS accounts for over 2,000 person days of space experience a year. The day-in and day-out slog of operating an aging orbital laboratory and learning to live there is slowly but surely preparing us for what comes next. This experience is shared by a partnership of 15 nations (USA, Canada, Russia, Japan, and 11 countries from ESA). However, the rising nation of China finds itself on the outside. Just like in many other sectors, China is finding its own way in space. Last year was a good one for the China National Space Agency (CNSA). Not only did they launch a brand new space station, Tiangong-2 and send a crew of 2 on a 30-day mission to the outpost, they also debuted a brand new Long March 5 heavy lift launcher while matching the US in successful launches on the year – twenty-two. A new medium-lift rocket, Long March 7, also debuted from a new coastal spaceport on Hainan Island, which should give CNSA more flexibility. CNSA’s recent white paper publically published outlining their five-year plan shows ambition but also should be a douse of cold water on people expecting a space race between China and the USA. China certainly has a lot to be proud of as only the third independent nation to place humans in space. But they have a long way to go to put themselves on par with the modern space programs in America and elsewhere. I look forward to their planned lunar sample return mission in 2017, which will give them a lot of “street cred” if they pull it off!

Obviously these are not the only happenings in space exploration and related science areas. I could go on about the exciting developments in exoplanet astronomy, a field that may provide worlds to explore decades or centuries from now, for example. We continue to live in a golden age of space exploration that started with the Galileo probe to Jupiter in the early 90s. For me, 2016 was a testament to the true diversity of the state of space exploration and should serve as a reminder to avoid tunnel vision. There are many facets to how we explore. It’s not just about shiny new rockets and capsules and astronauts, but its also not just about gathering science through a space telescope or a distant robotic probe. All these pieces fit together to move forward the state of our knowledge about the universe together. One of my favorite examples of this from last year was astronaut Kate Rubins’ work on gene sequencing while aboard the ISS. Talk about two sectors that do not traditionally intersect, at least not in the minds of the general public. Diversity – both in the space agencies doing the exploration as well as the type of exploration – will keep the dream alive. I can’t wait to see what we do on ISS this year but I also look forward to news out of China and India as they learn what it takes to fly in space.

The biggest problem with keeping up this steady cadence of exploration is how all these space agencies will pay for it, as the world faces challenging fiscal and security issues. Space is exciting – and important – but it is far from the first priority when it comes to setting budgets in most parts of the world. Fortunately, we have disruptive new players in the launch sector that can help us keep costs down. More on that in my next post.

Down to Earth

The crew of three Chinese taikonauts finished their 30-day stay aboard the Tiangong-2 space staion and returned to Earth last month.

A planned cargo resupply flight (with no astronauts aboard) launched from Kazakhstan on December 1 on its way to the ISS, but did not make orbit and crashed somewhere in a remote part of Asia. The next ISS resupply is a Japanese HTV vehicle launching next week.

Virgin Galactic continued their flight test program for the new SpaceShipTwo vehicle (named VSS Unity) with a captive carry flight on November 30 and then a glide drop test on December 3. Powered flights should be happening soon, but no specific dates are public. Here’s a photo gallery of the flight test.

In Orbit

Four other rockets launched since my last post on November 16, all successfully placing their payloads in orbit:

The ISS has had a very busy month, notwithstanding the loss of Progress 65. After the last three members of Expedition 50 arrived, they got quickly to work with last-minute packing of the Cygnus freighter, which they released two days later.

Since the Cygnus departure, the crew has been furiously working on their long list of on-orbit experiments. Thomas has someone found the time to tweet every day. Some of his best are below:

SpaceX posted an update to their accident investigation regarding the rocket that was lost on a launch pad in September. Here’s a direct link to their anomaly updates page. They hope to return to flight this year.

In Orbit

In launches, it has been a slow couple of weeks, with only two orbital launches since my last post on October 16th. It was quality over quantity though, as both launches were important and anticipated missions for ISS operations.

First, Orbital ATK was able to finally launch their upgraded Antares rocket with a Cygnus cargo craft on its way to ISS. The rocket launched on Monday October 17th and was captured at the ISS almost a week later on Sunday the 23rd. The delay was necessary due a higher priority launch and docking of three crew aboard a Soyuz (see below).

On Wednesday, October 19, the Soyuz rocket carrying the second half of Expedition 50 finally launched (after a spacecraft problem delayed them several weeks). The launch, rendezvous, and docking were flawless. The new crew of Shane Kimbrough Andrei Borisenko, and Sergey Ryzhikov arrived at ISS on the 21st.

There were 8 people in space only briefly (recall that two Chinese taikonauts are hanging out on their own space station right now). Expedition 49 had to hand over command to new Expedition 50 commander Kimbrough on the 28th before Anatoli Ivanishin, Kate Rubins, and Takuya Onishi undocked on Saturday night and landed safely a few hours later.

Speaking of the Chinese taikonauts, they docked successfully to the Tiangong-2 space station on October 20th and plan to stay for several weeks.

Around the Solar System

The ExoMars mission arrived at Mars on October 19th. The orbiter (known as TGO – Trace Gas Orbiter) made a successful orbital insertion burn but unfortunately, contact with the Schiaparelli lander was lost at the planned time of touchdown. The lander is suspected to be lost, but NASA’s Mars Reconnaissance Orbiter (MRO) was able to image the lander’s crash site, which should help with investigations. Below is an animated GIF showing the recent appearance of the lander in MRO imagery:

And here’s a closeup from the MRO’s HiRise camera.

In other bad news, the Juno spacecraft went into safe mode during its closest approach to Jupiter on October 18 and was not able to obtain scientific data. This came only a few days after an engine burn had been cancelled. Fortunately, mission controllers were able to command Juno out of safe mode on October 24 and perform at least one “trim” maneuver. The mission timeline will be impacted by the problem but there are still dozens of orbits left in the primary mission to gather data.

Here is a nice post with images about the preliminary results from Juno so far.

Speaking of spacecraft beaming data back to Earth, the data downlink from the New Horizons probe of its Pluto flyby last July has finally completed, 15 months later!

An opinion piece by Barack Obama appeared in CNN last week discussing his vision for America’s future in space and particularly, future missions to Mars.

Amid talk of a schedule slip of the first Starliner missions, Boeing announced they will need to add an aeroskirt for their launch configuration atop the Atlas V rocket (follow the link for an illustration).

Astronauts on the ISS opened up the BEAM module for another round of inspections (that’s the “expandable” module that was added back in May). Meanwhile, NASA announced that it is seeking commercial partners to build new functional modules for the ISS. Of course, the supplier of BEAM, Bigelow Aerospace, is one of the companies seeking the contract.

The launch of Orbital ATK’s Antares rocket (returning to flight almost 2 years after the last one failed after launch) was delayed until tomorrow evening due to a technical issue.

Earlier this evening, China launched a manned Shenzhou capsule with two crew aboard. They are heading to the new Tiangong-2 space station for an extended mission. When the latest ISS Soyuz crew launches in a couple of days, there will be 8 people in space! It has been very rare for the number to grow above 6 since the last Space Shuttle mission five years ago.

Around the Solar System

Due to some sticky valves in the Juno spacecraft’s propulsion system, the probe will not be making a scheduled burn to reduce its orbital period from over 50 days to just 14 days. NASA is waiting another orbit (so, until December) to investigate and then try again.

Astronomers have discovered a new distant unnamed object (2014 UZ224) which may be large enough to qualify as a “dwarf planet”. The object is smaller than Pluto and orbits about 5 times farther from the sun.

The ExoMars/Schiaparelli mission – a joint mission between ESA and Roscosmos – had some critical mission events today, including separation of the Schiaparelli lander and a critical orbital maneuver to setup for orbital insertion next week.

Jack Garman, who worked a support console for Apollo guidance and navigation, passed away on September 20th, at 72 years old. Garman is best known as being instrumental in the calls to proceed with landing on Apollo 11 when some guidance computer program alarms showed up at just 3,000 feet above the surface. Here’s the raw audio from that part of the landing which is always worth listening to again. Great example of flight control in action.

Neil Degrasse Tyson’s podcast StarTalk had a special episode hosted by astronaut Mike Massimino with guest interviewees, flight directors Royce Renfrew and Emily Nelson. Check it out here!

Musician and singer Grace Potter collaborated with NASA on a music video for her song Look What We’ve Become. It was filmed completely at NASA’s Johnson Space Center! Check it out below.

One of the biggest national stories of the last week was Hurricane Matthew, which came close to dolling out a devastating blow to the East coast of Florida. Fortunately, the most dangerous winds stayed offshore as it passed the Kennedy Space Center, resulting in some damage but nothing too serious.

In the battle of the New Space giants, there were two big stories in recent weeks. First, SpaceX CEO Elon Musk had his much anticipated presentation at the International Astronautical Congress (IAC) in Mexico. the speech presented a high level framework of his plans to visit Mars. Most of the details were focused on the rocket design and less on how humans would survive and thrive on Mars. Below is the full length video, but Ars Technica had a good analysis if you don’t want to watch all of it. Another good take on it from Phil Plait here.

If you are interested in just the 4-minute animation from SpaceX showing their imagined Mars mission architecture, jump to the second video below.

The other big story was Blue Origin’s successful in-flight abort test of their New Shepard rocket (personally, I am not sure if they have a separate name for the capsule or if New Shepard refers to the whole system. It was a pretty exciting launch and test. Jump to 51 minutes in the webcast replay below to watch!

Lots of good news regarding the ISS flight manifest. The next Cygnus cargo freighter, launching from Virginia for the first time in 2 years on Orbital ATK’s redesigned Antares rocket, should fly next Thursday, the 13th.

The following week, the next crew should launch on their repaired Soyuz craft. That launch is scheduled for Wednesday, the 19th.

There were two rocket launches since my last post. First, an Indian GSLV rocket launched a slew of satellites into orbit, including some from Algeria, USA, Canada, and India. Second, an ESA Ariane 5 rocket launched two communications satellites to a geosynchronous orbit on the 5th.

Around the Solar System

Check out this “video” (really an animated gif made from stills) of the Curiosity rover drilling on Mars! The rover has just officially entered its next two-year mission extension.

NASA announced new findings from the Hubble Space Telescope that reinforce the conclusion that not only does Europa have a subsurface ocean of liquid water, but that the water regularly exits the moon in powerful plumes (which could be theoretically sampled by a visiting probe).

In even more exciting planetary science news, NASA announced new analysis of data from the MESSENGER spacecraft (which finished its Mercury orbital mission last year). By analyzing imagery from the last part of MESSENGER’s mission, when it was at a lower altitude, scientists have concluded that the surface shows signs of recent contraction, meaning that Mercury is tectonically active.

ESA’s Rosetta mission ended on September 30th with a controlled descent into comet 67P/Churyumov/Gerasimenko.
