Down to Earth

Mattell launched a new line of “Inspiring Women” Barbie dolls. The release includes a doll of NASA’s Katherine Johnson, made famous by the movie Hidden Figures.

JPL posted a 360-video from inside the InSight lander test lab (this is the next mission to Mars launching in May).

Westworld director Jonah Nola showed the below video during a SXSW panel this weekend.

National Geographic’s March issue features NASA astronaut Peggy Whitson on the cover and an article by Nadia Drake which profiles a handful of other astronauts.

In Orbit

Two rocket launches since my last post a week ago:

  • March 6 – SpaceX launched a Falcon 9 rocket carrying two satellites for commercial companies.
  • March 9 – Arianespace launched a Soyuz rocket from Kourou carrying three communications satellites for O3b.

There has been a lot of talk lately of China’s defunct Tiangong-1 space station, and it’s imminent uncontrolled plunge back to Earth. Predictions are for early April.

Around the Solar System

NASA released some new imagery data and science results from the Juno probe in orbit of Jupiter. Some of the intriguing mysteries uncovered include the strange polar cyclones and the 3,000 kilometer deep wind patters. Phil Plait has an excellent summary at his blog.

Out There

Another asteroid on an interstellar hyperbolic orbit has been discovered. This object is likely from the Oort cloud, which makes it different than ‘Omuamua, which is believed to have originated in interstellar space.

2017 in Review

The year of 2017 will be remembered by most of my readers for reasons totally unrelated to spaceflight. It was a tumultuous year with political turmoil, social strife, acts of violence, and devastating natural disasters. Unfortunately, it is these negative stories that tend to embed themselves in our memories as we witness the arc of history unfold. Even when we zoom out to a wide angle view of decades or centuries, it is violence and conflict we remember. What were the biggest events of the 20th century? Wars, economic collapse, threats of annihilation, and social strife. I don’t have to remind you though, as a space fan, that most of the world shares at least one bright memory of the difficult last century: Apollo 11.

In a similar way, I’m hoping that through all the difficult times we face as a society in the 21st century, that spaceflight can be one of those bright spots that is a source of optimism and hope (although, surely not the only source). As Bill Nye is fond of saying “space brings out the best in us.” Spaceflight is an outlet for positive creative energy. Spaceflight applies technology in new ways, often leading to new inventions and sometimes entire industries. Spaceflight allows us to conduct important research that applies directly to the interests and concerns of everyone on Earth – from medical studies onboard the ISS to weather and climate satellites to space telescopes looking out for Near Earth Objects (NEOs).

Spaceflight is a bipartisan endeavor universally loved by young and old alike because it taps into something innate in us. Whether it’s the love of exploration and discovery or just the appeal of astronauts as wholesome hometown heroes, space has always been an easy sell to the public. Very few other uses of time and money are as generally noncontroversial (although we like to argue over specifics). There was a chance for space to get swallowed up in the political turmoil in Washington, DC this past year. Luckily, that didn’t happen. Instead, the space industry had another great year with very few setbacks.

Some readers may take issue with that statement and want to argue that it was not a great year for space. After all, NASA still has no confirmed administrator, XCOR went out of business, several programs slipped their launch dates (JWST, SLS, Orion), and Cassini ended its mission at Saturn (leaving us with a dearth of outer solar system probes). But if we look at those space programs or missions that are active and flying, we see lots of success in 2017 with few failures. The loss of Cassini should probably be spun as a positive story anyway – the planned retirement of a historic program of exploration – 13 years in Saturn orbit.

Other than the few things I listed above, the only other major setbacks of 2017 would be the five complete launch failures shown below (there were one or two other partial failures). Both Japan and New Zealand (Rocket Lab) lost rockets on their maiden launch. India, China, and Russia all lost one rocket each. The two remaining major space powers – ESA and USA – did not have any launch failures.

Country Vehicle Payload Maiden launch?
Japan SS-520 nanosat Yes
New Zealand Electron none Yes
China Long March 5 Comm sat No
India PSLV Nav sat No
Russia Soyuz Various No

2017 actually had the lowest launch success rate since 2011 and yet overall it felt like a very successful year (launch success was about 93% instead of the usual 95%). A few things contribute to this being a good year for rockets. First of course, is that 2 of the failures were test launches. If you remove them from the accounting, we are back at 95%. The second big reason is that none of the other failures led to an interruption in logistical support for the ISS. From 2014 to 2016, ISS operations lost four uncrewed logistical support rockets. After a string that bad, the last 13 months of successful flights (ten missions in all) feels positively blissful.

The third, and maybe most important reason this was a great year for rockets, was that SpaceX had no failures this year. In 2015 they lost an ISS resupply mission on ascent. In 2016 their year was cut short at 8 missions when a rocket blew up on pad 40 at Cape Canaveral. The backlog of customers was looming for a long 6 months while SpaceX worked on recovering from that latest failure. Then, last January they returned to flight with a launch for Iridium and haven’t let up since. Their accomplishments include: no launch failures, a record 18 launches, a record 15 first stage recoveries, and first reuse of a first stage. The other American providers, ULA and Orbital ATK, also had good years with 8 and 3 successful launches each with no failures.

As long as we get to space with chemically propelled rockets, everything hinges on how well our rockets are flying. We can’t really do a retrospective on the year without looking at these numbers. This has always been true, but what is particularly poignant from 2017 are those 18 launches from SpaceX. That’s fully 20% of all launches. Not only that, but they flew a lot of important missions. In 2017 alone they launched four times to the ISS and at least twice for the US military. In 2018 they plan to launch several times for NASA, including to the ISS as well as the Transiting Exoplanet Survey Satellite (TESS). At this point, it’s pretty clear that when SpaceX has a good year, the space industry has a good year.

In addition to the 10 successful cargo launches to the ISS this year, there were also 4 flawless crew launches to keep the record of 17 straight years of crewed operations going. NASA stepped up to 4 full-time USOS crew (which includes Japanese, Canadian, and European flyers), enabling even more research. NASA is now in full utilization mode of the ISS. Hundreds of experiments are being conducted each year – from physical science to medicine to biology to botany to astronomy – and each SpaceX Dragon brings up more externally mounted autonomous payloads such as last year’s aerosol monitoring payload (SAGE III) and a neutron star telescope (NICER), among others. The ISS has become an important platform for efficiently deploying small satellites, with dozens launched from the Japanese robotic arm last year.

The ISS looks well positioned for the future, with a healthy manifest of crew and payloads coming up as well as the exciting prospect of even larger crews, once Boeing and SpaceX successfully demonstrate flight of their new crew transportation systems. In the meantime, important maintenance has been ongoing to ensure that ISS can operate well into the 2020s. Early in the year a Japanese cargo vehicle, an HTV, brought up a new set of lithium ion batteries, the first in a series of battery replacements over the next few years that will keep the solar power flowing. The batteries were replaced in a series of 3 spacewalks last January. Ultimately, ISS astronauts would complete 10 successful spacewalks last year with no major issues.

The year in ISS was underscored by Peggy Whitson’s amazing flight. At 57 years old, Whitson now holds the record for most days in space of any American astronaut in history (665) as well as an impressive 60 hours of EVA time that puts her number 3 all time behind Anatoly Solovyev and Michael Lopez-Alegria. Peggy’s 289 day mission was almost entirely unprecedented. Not only was Whitson praised as a “space ninja” by her crew mates for her work onboard the ISS, but even made a wide impression outside of NASA and received a Woman of the Year award from Glamour Magazine. The crews aboard the ISS continue to bring the wonder of spaceflight home to us through their social media engagement and excellent educational outreach events. If you aren’t checking this link for the latest pictures from space every morning, you are missing out on a little bit of daily wonder.

The ISS is of course not the only game in town. NASA has very active planetary science and astronomy programs, not to mention similar missions from ESA, JAXA, and other agencies. 2017 saw no new launches of solar system probes (that’s right, zero) but many active missions made progress and the only “failure” being the end of Cassini. Mars is incredibly active with 8 missions. Two NASA rovers, Opportunity and Curiosity, are providing a wealth of insights into the wet history of Mars. The most exciting discoveries from those robots are likely yet to come. Two asteroid sample return missions, OSIRIS-Rex from NASA and Hayabusa 2 from JAXA, remain in interplanetary cruise phase. New Horizons is on its way to visit a Kuiper Belt Object next year, Juno remains in orbit at Jupiter, and Dawn continues to explore the largest asteroid, Ceres.

Some of these missions we heard big news from this year, such as Cassini’s analysis of the ocean plumes from icy Enceladus. We also gained a new understanding of the winds and storms of Jupiter from Juno. Not to mention the absolutely stunning images we have been treated to from JunoCam.

But overall, space exploration, especially planetary exploration, is a long game. Spacecraft take years to reach their targets and then spend sometimes months or years (at least for orbiters and rovers) slowly collecting the data they need to learn something new from our mysterious solar system neighbors. So there were no splashy launches or touchdowns in 2017. Instead, the hard work from years past continued to pay off with well built spacecraft going about their daily business. 2017 was a great year in this respect. Years like this lay the foundation for big discoveries to come; it’s just that we have to wait a bit for the papers to be published. The only real downer this year is probably that Curiosity’s drill is still out of commission.

There is of course, a lot more to cover. Spaceflight is a big industry that goes far beyond just the ISS or big planetary exploration missions. New Space, for instance, had a lot of interesting updates this year. In addition to Rocket Lab making their first launch attempt, Blue Origin demonstrated further progress on their New Shepard vehicle as well as their BE-4 engine, Virgin Orbit moved a few steps closer to their first test launch with several engine tests, and Sierra Nevada conducted their first free glide flight in several years.

Then there’s astronomy. So much is happening in astronomy these days that it deserves a lengthy retrospective all its own. Here are some highlights of last year in a quick paragraph. Many interesting exoplanets were discovered, such as the fascinating Trappist-1 system with three potentially habitable planets. But Ross 128b is my favorite potentially habitable planet, because it is less than 11 light years from Earth. Let’s go! Other exciting developments in astronomy included more neutron star collisions discovered via gravitational waves and also the fascinating cigar shaped something known as ‘Omuamua which flew through our solar system from somewhere this past October (more to come on this we hope).

As we look to the future, we can see that there is a lot to learn. The ISS has years of science to conduct – managers are furiously looking for more ways to maximize timelines and target the most likely breakthroughs. Meanwhile there are dozens of worlds here at home in our solar system yet to explore, not just with probes already launched but many to come (launches to Mars, Mercury, and the Moon in 2018). And most intriguing of all, there are thousands upon thousands of worlds to explore out there, beyond our own star.

The more we look, the more we find. And the more we find, the more questions we think to ask. This is the optimistic and worldview expanding impact of science. We are losing the explorers of the last century – Apollo legends Gene Cernan, Dick Gordon, and John Young all passed away in their 80s in the past year. But it’s hard not to see the vast opportunity available to the current generation of explorers in this century. Perhaps some day we will look back at this time period as a changing of the guard. It is hard to say without the benefit of hindsight. If nothing else, for those of us that are inspired by scientific discovery and exploration, 2017 showed us that spaceflight can be – and probably always will be – a candle in the dark.

Down to Earth

Sierra Nevada Corporation completed a successful free-flight landing test of their Dream Chase space plane. The test was the first free-flight since 2013, when they had a landing gear issue during their first test.

XCOR Aerospace, a company that spent over a decade trying to develop their own space plane, has filed for chapter 7 bankruptcy (i.e., their assets will be auctioned off).

Another veteran astronaut of the Apollo era has passed away. Apollo 12 Command Module Pilot Dick Gordon died last week at 88 years old. In addition to orbiting the moon, Gordon flew on the Gemini 11 mission with Pete Conrad and later worked on the Space Shuttle program.

During an engine test last week, SpaceX had an incident with a qualification unit of their new Merlin engine design. The engine basically blew up but no one was injured.

If you get up before dawn tomorrow, you will have a chance to see a conjunction of the planets Venus and Jupiter. They will rise very close together in the East.

In Orbit

Three orbital rocket launches since my last post:

  • November 5 – China launched two new Beidou navigation satellites.
  • November 8 – ESA launched a Vega rocket carrying an earth-observing satellite for Morocco.
  • November 12 – Orbital ATK launched an Antares rocket from Virginia carrying a Cygnus cargo freighter to the International Space Station. It will arrive on station Tuesday morning.

The independent NASA visitor center in Houston, Space Center Houston, has announced a Kickstarter campaign to help raise additional funds for their project to restore MOCR2 in the Christopher C. Kraft Mission Control Center on the Johnson Space Center campus. MOCR2 is most famous for being the flight control room during the Apollo 11 lunar landing. However, it was used for every Apollo flight starting with Apollo 8, as well as many Space Shuttle missions. In addition to being a site of much triumph (Apollo 8, Apollo 11, STS-1, etc) it was also the active control room during the Apollo 1 fire and the launch of Challenger on STS-51L. Here’s the Kickstarter link. I have already pledged!

Up on the actual ISS, the crew has been busy getting ready for the arrival of the next crew on July 27th. The Progress cargo craft departed with trash on July 20th.

But the NASA crew of Jack Fischer and Peggy Whitson still had time to share their mission with us with a couple informative videos:

Only one rocket launch since my last post on July 9th. Russia launched a Soyuz rocket from Kazakhstan carrying payloads for commercial companies, including an impressive array of small “Dove” satellites for American company Planet. Even more impressively, Planet captured this beautiful footage of the launch from one of their spacecraft already in orbit:
