Down to Earth

SpaceX’s latest Dragon capsule left the ISS on March 19th and was successfully recovered by the company at sea.

A new exhibit about Valentina Tereshkova, the first woman in space, has opened at the Science Museum in London.

The White House released their budget proposal for 2018, including proposed spending on NASA. The proposal funds NASA at $19.1 billion, which is a slight cut. Taking into account inflation, it comes out to a few percent less than what NASA is working under in 2017. If you really really love reading about budgets, here is a super long post from Casey Dreier at the Planetary Society breaking down the proposal.

The European Space Agency is having trouble with their only orbital launch site down in French Guiana as a general strike is causing most of society in the small French territory to grind to a halt. There had been an Ariane 5 rocket launch planned for last week that continues to be delayed.

In Orbit

There have been three successful orbital rocket launches since my last post on March 12th:

Meanwhile, SpaceX is working towards their next rocket launch. The next Falcon 9 rocket will be a commercial launch of the SES-10 communications satellite. The exciting part of this mission is that it will be the first flight of a reused first stage booster. The static fire test was completed today, with launch scheduled for Thursday evening.

On the International Space Station, the Expedition 50 crew is very busy with a series of spacewalks that will serve as Commander Shane Kimbrough’s send off before he comes home in early April. The first spacewalk was conducted last Friday, March 24th, when Kimbrough and Thomas Pesquet spent six and a half hours outside conducting various repairs and upgrades.

One of the spacewalk’s tasks was to disconnect Pressurized Mating Adapter 3 (PMA-3) before it was robotically moved this past Sunday to its new home on top of Node 2 for future dockings of the Dragon and Starliner spacecraft.

The next spacewalk is this coming Thursday. here is an hour long briefing from last week that describes the spacewalk plans in detail (keep in mind the discussed arrival of the Orbital ATK Cygnus cargo craft has since slipped):

SpaceX successfully conducted the static fire test for their next rocket launch from Pad 39A at the Kennedy Space Center. A Falcon 9 carrying a commercial satellite will liftoff very early Tuesday morning, March 14th.

In Orbit

Only one orbital rocket launch since my last post. A European Space Agency Vega rocket launched the Earth-observing Sentinel-2B satellite from French Guiana on March 7th.

As usual, there are lots of good pictures from the crew on the ISS to share. Here’s a selection.

New data from the Dawn probe in orbit of Ceres indicates that the “bright spots” are much younger than the craters they inhabit. This is evidence of relatively recent cryovulcanism.

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

Astronauts Mike Fossum and Mike Baker announced their retirement from NASA last week.

NASA announced that it will be funding two new robotic missions to study distant asteroids. The Lucy probe will take many years to go all the way out to study the Trojan asteroids, which share Jupiter’s orbit. The Psyche probe will travel to an asteroid named Psyche which is a solid iron asteroid. It will be the first large iron asteroid visited by a spacecraft.

In Orbit

The one and only orbital launch since my last post on January 5th was yet another Chinese rocket. This launch on the 9th carried several small Earth observation satellites into orbit.

Up on the ISS, the Expedition 50 crew completed two successful spacewalks to upgrade a portion of the space station’s power systems to use new lithium-ion batteries. Last Friday, January 6th, Peggy Whitson and Shane Kimbrough completed the first spacewalk and yesterday, Friday, January 13th, Shane Kimbrough and Thomas Pesquet completed the second. Whitson’s 46 hours over 7 spacewalks puts her in an elite class at 14th on the list of most spacewalking hours ever by a human. Shane also has an impressive 25 hours over only 4 EVAs, but it keeps him off this list of top 30 humans on Wikipedia (30th place is just over 38 cumulative hours. Also note that Whitson would only need one more spacewalk on her current mission to pass Sunita Williams’ 50 hours in 7th place for most hours for a woman). Here are some video summaries from NASA and pictures from the spacewalks:

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:

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).

In Orbit

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.

Down to Earth

Easily the top story of the past couple of weeks (sorry, OSIRIS-REx) was the loss of a Falcon 9 rocket with its commercial satellite payload on the pad during a pre-launch static fire test (video below). The pad, Space Launch Complex 40 (SLC-40) was damaged in the fire (pictures here) and SpaceX is currently still investigating the cause. It is impossible to speculate on what kind of setback this will cause in their launch manifest until some notion of the cause is determined. SpaceX still has one operational launch pad in California.

Just 3 days before the SpaceX pad fire, the Chinese space program suffered a failure in what is apparently the first launch failure of the year. The Long March 4C rocket was expected to put a reconnaissance satellite in orbit.

As for positive news, NASA’s troubled Mars lander InSight has been greenlit for a launch sometime in 2018.

Another goodie was Virgin Galactic conducting the first test flight of the new SpaceShipTwo (although just a captive carry flight).

Check out this blog post from one of the recent crew members of NASA’s asteroid mission simulation, HERA. Tess was on the crew of HERA 11.

The most important thing to come “down to Earth” last week was the crew of Expedition 48. Jeff Williams, Oleg Skripochka, and Aleksey Ovchinin landed in Kazakhstan last Wednesday after a flawless undocking and re-entry.

In Orbit

Before Expedition 48 ended, Jeff Williams and Kate Rubins conducted their second spacewalk in as many weeks, repairing and upgrading a slew of items outside the ISS.

Fortunately, there were at least two successful launches to offset the failures in early September. First, an Indian GSLV Mark II rocket lofted a weather satellite. Secondly, a ULA Atlas V rocket launched NASA’s OSIRIS-REx probe on its 7-year journey to visit an asteroid and return to Earth with samples.

Around the Solar System

On Mars, the Curiosity rover is currently trundling through some incredible landscapes, snapping photos of beautiful buttes and rock layers.

Juno continues to return data from Jupiter, including a stunning image of the north pole.

And last but not least, one of the coolest stories of the last week, the European Space Agency finally located the lost comet lander, Philae, just weeks before the orbiter Rosetta is due to end its own mission. Check out the pictures!

Blue Origin launched their reusable New Shepard rocket for the fourth time, with a hosted webcast this time. Here is a video of the flight:

A Saturn V first stage, meant to be used on the Apollo 19 flight, was moved to the Stennis Space Center’s visitor center for display, along Interstate 10 in Mississippi.

During a congressional hearing last week, the issue of astronaut post-mission health care was discussed.

This is not strictly space news, but the deep winter rescue mission from the South Pole is just as harrowing and difficult as spaceflight in some ways.

A team of astronauts are going on a multi-night spelunking trip this month as a spaceflight analog training mission.

The new 3D printer aboard ISS by Made In Space has printed its first functional tool.

The Orbital ATK Cygnus cargo vessel was released from the ISS on June 14th and re-entered the atmosphere on June 22nd. In the meantime, NASA conducted the SAFFIRE in-flight fire experiment. Here’s some of the video they recorded:

Also returning to Earth this month, but in a more controlled fashion, was there astronauts aboard Soyuz TMA-19M: Tim Peake, Tim Kopra, and Yuri Malenchenko.

Here are all the orbital launches since my last post on June 6th:

  • A Russian Proton rocket carrying a communications satellite (June 9).
  • A ULA Delta IV rocket launch from Florida carrying a spy satellite (June 11).
  • A Chinese launch of one of their navigation satellite (June 12).
  • A SpaceX Falcon 9 rocket with two communications satellites (June 15).
  • A European Ariane 5 rocket carrying two communication satellites (June 18).
  • An Indian PSLV rocket carrying a slew of satellites including a flock of PlanetLabs Doves (June 22).
  • A ULA Atlas V rocket carrying a US military communications satellite (June 24).

The SpaceX launch, as usual, was the most exciting, with another ASDS landing attempt. They missed the landing this time. Here are some pictures of the wreckage returning to port.
