Down to Earth

A new Kickstarter campaign seeks to build replicas of the Apollo guidance computer DSKY (Display and Keyboard) interface.

NASA’s 15th Human Exploration Research Analog (HERA) mission started last week at Johnson Space Center. Four crew members will spend 45 days isolated on a simulated deep space mission.

The much anticipated Falcon Heavy launch is now less than 48 hours away. Eric Berger of Ars Technica has an excellent discussion about the new rocket and what it could mean for the industry (if successful).

In Orbit

Four successful orbital rocket launches since my last post

• Jan 31 – SpaceX launched a Falcon 9 rocket carrying GovSat-1 from Florida.
• Feb 1 – Russia launched a Soyuz 2.1a rocket carrying multiple satellites.
• Feb 2 – China launched a Long March 2D rocket carrying the China Seismo-Electromagnetic Satellite (CSES).
• Feb 3 – Japan launched an SS-520-5 rocket and placed a satellite in orbit. This was the second flight of the small Japanese launcher that failed on its inaugural launch last year.

A spacewalk conducted by Alexander Misurkin and Anton Shkaplerov on the International Space Station broke the Russian record for longest spacewalk, at 8 hours and 13 minutes.

An amateur astronomy discovered a NASA satellite that had been missing for over 10 years.

Around the Solar System

NASA published a beautiful composite panorama from the Curiosity rover looking back down the slopes of Mt. Sharp.

Curiosity also took a new selfie, looking the other direction.

Out There

Astronomers have announced that using gravitational microlensing they have discovered evidence of planets in another galaxy for the firs time.

Down to Earth

The US federal government was shutdown briefly over the past weekend, and had some impacts to NASA, but ended by Tuesday morning. The federal budget decision has been moved by Congress to February 8th.

SpaceX completed the long-awaited “hot fire” test of their Falcon Heavy rocket on the launch pad in Florida. The company has reportedly set their launch date February 6th.

The flight controller consoles in NASA’s Historic Mission Control at Johnson Space Center began being removed this week as part of a longterm restoration effort.

NASA’s InSight lander, the next mission to Mars, launching this year, had its solar arrays tested at Lockheed Martin.

During the “Year of Education” onboard the ISS, astronauts will record lessons originally planned for Christa McAuliffe’s teacher-in-space flight on Challenger in 1986.

Johnson Space Center director Ellen Ochoa plans to retire this year.

The Google Lunar X Prize will end this March with no team winning the $20 million prize for sending a private rover mission to teh moon.

In Orbit

There were two rocket launches last week:

• January 25 – China launched a Long March 2C rocket carrying three satellites.
• January 25 – ESA launched an Ariane 5 rocket carrying two communications satellites.

The Ariane 5 rocket had some kind of anomaly with the upper stage and placed the payloads in the wrong orbit.

ISS astronauts Mark Vande Hei and Scott Tingle completed a spacewalk last Tuesday to service to Canadarm-2. Unfortunately, an issue discovered after the spacewalk has caused a change of plans, and a second excusion planned for this coming Monday will be used to enact some repairs.

Around the Solar System

Some news from Mars:

• Researchers hope to observe a global dust storm on Mars in the near future to validate a theory that dust storms contribute to the loss of the planet’s atmosphere.
• Data from NASA’s Mars Reconnaissance Orbiter (MRO) has found potential ice sheets at mid-latitudes on the red planet.

Down to Earth

Some recent crew assignment changes for the ISS have been receiving a lot of press, including the replacement of Jeanette Epps with Serena Aunon-Chancellor for a launch this summer. NASA has not provided specific details on the reason for the change.

As of Saturday morning, the US federal government has no official funding and must shutdown many services. This shutdown affects NASA and its field centers. The specific impacts to NASA operations will become more clear if the shutdown extends into the work week on Monday morning. In the meantime, NASA will press forward with the ISS spacewalk on Tuesday.

There was a lot of talk last week about an update on the schedule for NASA’s Commercial Crew Program, which has slipped according to a report from the Aerospace Safety Advisory Panel (ASAP). There was also a Government Accountability Office (GAO) report on the same topic.. The reports outline a few issues that the commercial providers – SpaceX and Boeing – both need to work through before their rockets and capsules can be certified to flight NASA astronauts to the ISS. Both companies answered questions at a congressional hearing following the report on Wednesday.

SpaceX still has not conducted a static fire of the Falcon Heavy rocket on Pad 39A. They are expected to try again this coming week with a potential launch before the end of the month.

In Orbit

The following rocket launches occurred last week:

• Jan 17 – Japan launched an Epsilon rocket carrying an Earth observing satellite.
• Jan 19 – China launched a Long March 11 rocket carrying several small satellites.
• Jan 20 – ULA launched an Atlas V rocket carrying a missile warning satellite for the US government.
• Jan 21 – Rocket Lab finally reached orbit with their second rocket, Still Testing, delivering some small satellites.

Out There

A detailed study of Fast Radio Burst (FRB) 121102, one of the few repeating signals, has yielded a new hypothesis that these highly energetic events are caused by massive black holes.

NASA has demonstrated the concept of deep space navigation using neutron stars with the NICER payload onboard the ISS.

Down to Earth

Virgin Galactic conducted their first glide flight of SpaceShipTwo since last August.

SpaceX’s Falcon Heavy has been attempting to conduct a static fire test ahead of launch, but has scrubbed three days in a row. It has been rescheduled for Monday.

#FalconHeavy static fire update: Looks like static fire is moving to Monday with an approximate target time of 1600 EST (2100 UTC) for the opening of the test window.

In the case of the SpaceX launch, there have been many reports from reliable journalists over the past week that the classified Zuma payload perhaps did not reach orbit. However, no official statement has yet been forthcoming.

Upcoming launches of interest include a ULA Atlas V from Florida on Jan 19, the next Rocket Lab Electron launch attempt on Jan 20, and SpaceX’s Falcon Heavy test flight (possibly on Jan 25?).

On the ISS, the 13th SpaceX Dragon mission ended successfully with release and splashdown. SpaceX ships are currently retrieving the capsule to return its science samples.

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.

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.

There were five orbital rocket launches since my last post, two weeks ago:

• Dec 23 – SpaceX launched a Falcon 9 rocket from Vandenberg in California, carrying communications satellites for Iridium.
• Dec 23 – JAXA launched an H-IIA rocket carrying two scientific satellites.
• Dec 23 – The Chinese space agency launched a Long March 2D rocket carrying an Earth-observing payload.
• Dec 25 – The Chinese space agency launched a Long March 2C rocket carrying payloads for the Chinese military.
• Dec 26 – Roscosmos launched a Zenit rocket carrying a communications satellite for Angola.

The Anogosat-1 payload initially had a problem and lost comm with ground control. However, reports in the past day or two indicate that communications have been restored.
