Down To Earth

Last week the US Senate passed a bill named the “U.S. Commercial Space Launch Competitiveness Act”.  One of the most talked about provisions in the bill allows private citizens or companies to lay claim to asteroid resources.

Virgin Galactic announced that they have hired their first female test pilot: Kelly Latimer, who has flown for the USAF and NASA.

An object known as WT1190F re-entered the Earth’s atmosphere and broke up over the Indian Ocean on November 13th. The object was thought to be a rocket stage from an Apollo mission. Astronomers onboard an airplane caught some pictures of the event.

This is pretty cool:

In Orbit

In the past week, only one rocket blasted into orbit: an ESA Ariane 5 rocket with communications satellites for India and Saudi Arabia. The next launch in support of the ISS is still a few weeks away: an Atlas V carrying a Cygnus freighter for Orbital ATK.

Around the Solar System

I love this animated mission update on the Rosetta/Philae mission from ESA.

New analysis indicates that Mars’ small moon Phobos may only have millions of years to live. Due to its low orbit, it is getting torn apart by tidal forces, which cause the strange “grooves” on its surface.

New images of large mountains on Pluto may be evidence for “ice volcanoes” (or “cryovolcanoes”).

Check out this animation which shows the different spin rates of Pluto’s 5 moons.

Astronomers have discovered a new distant solar system object which may be the most distant rocky body known. V774104 is about half the size of Pluto and orbits several times further away.

Out There

Newly discovered planet , GJ 1132b, is the closest planet of about Earth’s size yet discovered, at only 39 light years distant. Unfortunately, the planet is tidally locked and very close to its star, making it not a fun place.

The current head of JPL for 15 years, Charles Elachi, is retiring. Here’s a brief but good interview with him from Pasadena Star News.

NASA has delayed its decision to award ISS cargo flight contracts starting in 2018 until next year. The current contracts being fulfilled by SpaceX and Orbital Sciences run out in a few years and 5 companies have submitted proposals for the new award (SpaceX, Orbital, Sierra Nevada, Boeing, and Lockheed Martin).

NASA will be accepting applications for a new class of astronauts starting December 14th.

In Orbit

Scott Kelly and Kjell Lindgren completed their second of two planned spacewalks during their ISS mission this past Friday.

In orbital rocket news, China had two launches last week: first, a communication satellite on November 3rd and a military reconnaissance satellite on November 8th, bringing their total on the year to 14 with no failures. For comparison, the USA is 16 for 18, Russia is 19 for 21, and ESA is 7 for 7.

A new US Air Force rocket, intended for small payloads, was supposed to reach orbit from the Hawaiian Island of Kauai last week, but had an anomaly on ascent and was lost.

Speaking of rockets, a submarine-launched missile test was seen by many residents on the US west coast on Saturday evening, November 7th.

Around the Solar System

Newly-announced findings from NASA’s MAVEN spacecraft are helping scientists determine what happened to Mars’ atmosphere. Mars has no powerful magnetic field like Earth, so it is suspected that the solar wind has been blasting Mars’ atmosphere away into space over the eons.

The New Horizons spacecraft has now completed all four course correction burns needed (assuming they are all on target) to get to object 2014 MU69 in 2019.

Down to Earth

There was a workshop in Houston last week for technical discussion about selecting future landings sites for missions to Mars. It may seem a bit premature, with NASA saying missions to Mars won’t occur for 20 years, but engineers would like to take advantage of the excellent capabilities of the Mars Reconnaissance Orbiter to get early high resolution imagery of potential targets.

The US Congress passed a federal budget bill that avoids “continuing resolution” levels of funding for the rest of Fiscal Year 2016. The appropriations negotiations for specifics, like how much money NASA will receive, is not yet decided, but generally a budget provides more flexibility than a continuing resolution. Bottom line is that space policy fans have to wait to see how their favorite NASA programs are affected, but this is hopefully good news.

Check out this article at The Atlantic that does a good job of explaining the complexities and nuances in the political battle over the construction of the Thirty Meter Telescope on Maunakea in Hawai’i.

In Orbit

In rocket news, only one Chinese launch along with the launch of a new GPS satellite from Florida this past week. The next launch to the ISS will be a Cygnus resupply on top of an Atlas V rocket in early December. Later today, the first orbital launch from Hawai’i’s island of Kauai will take off from USAF’s Pacific Missile Range Facility.

Up on the ISS, astronauts Scott Kelly and Kjell Lindgren got to go on their first EVA ever! The EVA had a variety of tasks (it was in fact referred to here at mission control ambiguously as simply the “ISS Upgrades EVA”). The guys get a second walk outside later this week on Friday, November 2nd.

Meanwhile, on November 2nd, NASA marked 15 continuous years of habitation onboard the ISS.

Around the Solar System

The Cassini spacecraft conducted one of its closest flybys of Saturn’s icy moon Enceladus, passing within 30 miles of the surface and flying right through the “plumes” of water ice flowing out from the subsurface ocean.

A recent astronomical study of Europa – an icy moon of Jupiter with an ocean, much like Enceladus – revealed areas on the surface that appear to have a unique composition, probably caused by the sea water mixing with the surface ice.

A very large asteroid (2,000 feet) called 2015 TB145 flew past Earth this past weekend at a distance of about half a million kilometers. Heres a radar image of the rock; here’s some videos of the flyby.

The New Horizons spacecraft has conducted the first of its course correction thruster firings needed to reach its next target – a small Kuiper Belt object flyby in 2019.

I am back from a little “fall break”. This post should catch you up on the big things that have happened since my last post in September.

Down to Earth

George Mueller, head of NASA’s Office of Manned Space Flight in the 60s, died at an age of 97. There is at least one book about his contributions to the space program available on Amazon.

Estonia is now a full member of the European Space Agency.

A watch worn by Apollo 15 commander Dave Scott on the surface of the moon recently sold at auction for over one million US dollars. This is not one of the Omega Speedmasters which were given to all the crews (all of which are now owned by the Smithsonian). Instead this was a backup Scott wore when his Speedmaster broke.

An Israeli team called SpaceIL has secured a launch contract on a Falcon 9 rocket for their entry in the Google Lunar X Prize.

Blue Origin announced that it will center its launch operations at Cape Canaveral.

NASA dropped a large archive of photos from Project Apollo to Flickr.

In Orbit

It’s been a busy month of rocket launches. Since my last post on September 26th there have been nine successful launches to orbit: one by India, three by China, one by the European Space Agency, two by Russia, and two by America. Only one of those launches was in support of International Space Station operations: an unmanned Progress resupply mission from Russia. You can see a great list of all launches at “2015 in Spaceflight” on Wikipedia.

In addition to the launches, the Japanese HTV-5 cargo vehicle was successfully undocked and deorbited from the ISS during the last week of September.

Other happenings on the ISS included a debris avoidance maneuver on September 27th, some cubesat deploys, the Progress docking, Scott Kelly breaking the record for most days in space by an American, and some great imagery of Hurricane Patricia.

Around the Solar System

Science data from the New Horizons flyby of Pluto continue to come in, including this awesome picture showing the blue glow of the planetoids thin atmosphere.


NASA made a big announcement at the end of September about Mars research, revealing that the Mars Reconnaissance Orbiter had imaged evidence of water flowing (intermittently) on the surface of Mars. While previous NASA missions had confirmed that water is present and had flowed in streams and rivers in the ancient past, this is the first evidence of a modern water cycle. As usual, Emily Lakdawalla has excellent coverage.

NASA is posting daily images of the Earth from the DSCOVR satellite to an interactive website.

A rather large Near Earth Asteroid (NEA) at 500 meters across will buzz the Earth-Moon system on October 31st, but is not in danger of impacting our planet.

NASA has selected five new flight directors for manned spaceflight programs.

Last week in Houston a new opera titled ‘O Columbia’ premiered for just two nights at the Houston Grand Opera. The production incorporated the tragic loss of Space Shuttle Columbia in the second act. I didn’t get to see the show, but according to The Houston Chronicle a preview at the Johnson Space Center received a standing ovation.

Don’t forget to go out Sunday evening, September 27th, and see the lunar eclipse!

In Orbit

Two more orbital rocket launches last week. The first was a Rokot launch vehicle from Russia with several military communications satellites. China seems to be on a roll this month and launched another new rocket, the Long March 11, with several cubesats.

On Monday, September 28th, the Japanese HTV5 cargo vehicle will leave the ISS. You can follow along on NASA TV.

Since it’s a bit of a slow week for spaceflight news, here are some cool pictures from ISS as filler!

Tonight, the Expedition 44 crew of Gennady Padalka, Andreas Mogensen, and Aidyn Aimbetov will undock from the International Space Station and land in Kazakhstan. Follow along on NASA TV, with undocking at 5:29 PM Eastern.

During his short stay on ISS, Mogensen has been very busy trying to get as much science and engineering done for the European Space Agency as he can, including remotely operating a robot on the ground from space! Very cool.

Here’s a quick video from Mogensen about living in ESA’s Columbus module on ISS.

Early Friday morning, the European Space Agency launched a Soyuz rocket with two Galileo satellites into orbit. Galileo is ESA’s analog to the American launched GPS navigation system. Galileo is up to 10 satellites in orbit, but it will take many more to have a complete system (GPS has 31 active satellites).

All of the big events last week up at the ISS went fine. First, on Monday, HTV5 rendezvoused with the station on time and was captured with Canadarm-2. Later in the week, the crew of Soyuz TMA-16M strapped into their re-entry couches for a quick 30 minute fly around to change docking ports. Here’s an awesome time lapse of the “relocate”.

A few orbital rocket launches this past week, but none related to the ISS program. Here’s a rundown of the three launches from three different nations: India launched a communications satellite on a GSLV rocket, China launched a military satellite on a Long March 4C rocket, and Russia launched a commercial communications satellite on a Proton rocket. An Atlas V was supposed to launch from Florida with a military satellite but was delayed due to tropical storm Erika.

Here’s a nice animation by ESA about astronaut Andreas Mogensen’s flight to ISS next week. Soyuz TMA-18M is slated to launch with the next ISS crew on Wednesday, September 2.

As usual, lots of good photos from the ISS were posted to Twitter by the current crew, including some great shots of active tropical storms and hurricanes. Here’s a selection.

Veteran astronaut Steve Swanson, who flew on the space shuttle and commanded the ISS last year, is retiring from NASA. According to his Wikipedia page, he has spent an impressive 195 days in space with almost 28 hours of spacewalk time across 5 EVAs. This leaves NASA with 45 active astronauts (which doesn’t count ESA and JAXA astronauts who are qualified to fly to ISS).

Last week an important engine test in the development of the new SLS rocket was conducted at Stennis Space Center. The RS-25 engine was run for almost a full ten minuets. Here’s a video (test starts at 31:15).

In Orbit

Last Monday, August 10th, two Russian Cosmonauts went outside the ISS for a spacewalk. Padalka and Kornienko spent about five and a half hours outside. It was Padalka’s tenth spacewalk, which should put him nicely on this list once it is updated.

Later in the week, on Friday morning, a Russian Progress cargo craft undocked from the aft port of the ISS. That port will be empty until Soyuz 42S does a “relocate” from the Poisk port later this fall. The relocate is needed to free up Poisk for the docking of the next Soyuz. There will be three Soyuz onboard for a direct handover this fall.

Some cool stuff happened inside the ISS this past week as well. The astronauts were able to eat some red romaine lettuce grown on the space station in the “VEGGIE” experiment.

Japanese astronaut Kimiya Yui did some remote robotics experiments.

The launch of the next ISS resupply flight from Japan has been delayed to Monday, due to bad weather.

Also in ISS cargo news, Orbital Sciences announced they will launch not just one but two or more of their Cygnus cargo resupply missions on someone else’s rocket. Orbital is working hard to recertify their Antares rocket with new Russian engines, following the loss of one of their rockets last October. In the meantime, they are buying Atlas V rockets from United Launch Alliance in order to fulfill their NASA contract.

Last Monday, SpaceX announced preliminary findings related to the loss of a Falcon 9 rocket and its Dragon cargo mission last month. Here’s the companies official statement on their investigation so far. They have found that a structural support (or “strut”) holding up a pressurant tank in the second stage failed. Elon Musk hopes a delay of only a few months to their manifest.

Tony Antonelli, who piloted two space shuttle missions, has retired from the astronaut office.

The Smithsonian Institution has started a new Kickstarter campaign called “Reboot the Suit” to raise money to restore Neil Armstrong’s moonsuit. The restoration is planned to be completed in time for a new exhibit for the 50th anniversary of Apollo 11 in 2019. I pledged!

Three launches from the Earth’s three spacefaring nation’s this past week: first, a Russian Soyuz rocket launched from Kazakhstan on July 22nd, followed a few hours later by a successful docking to ISS. The crew is now back up to full strength of 6, with the addition of Oleg Kononenko, Kimiya Yui, and Kjell Lindgren. Lindgren and Yui are on Twitter, so you should follow my “people in space” Twitter list.

Second, a Delta IV rocket launched from Florida on July 23rd. The mission delivered a new military communications satellite to orbit.

China also had a successful orbital launch last week. A Long March 3B delivered two navigation satellites to orbit on July 25th.

NASA announced the discovery of Kepler-452b, a small planet around a Sun-like star about 1,400 light years distant. This is the most similar planet in size and circumstance to Earth that we have yet found, but it still has 1.6 times Earth’s diameter (mass, and thus surface gravity, unknown). However, the fact that it is so small and in the habitable zone, makes it an awesome discovery.

Obviously the big news this week was that New Horizons had its encounter with Pluto this past week. My space news feed was almost entirely Pluto news starting on July 12th, two days before the encounter. Rather than provide you a dozen links, some of which might be out of date, I would just suggest going over to The Planetary Society blog for up to date coverage of the latest pictures coming in from the outer solar system. Ok, on with some non-Pluto news…

This week marks the 40th anniversary of the Apollo-Soyuz Test Project, the first joint manned spaceflight between the US and Russia (the USSR at the time). The mission is today remembered as an early precursor to the partnership that led to the ISS. NASA TV did a nice piece marking the anniversary, with interviews with the two commanders: Leonov and Stafford. Check it out! (jump to 9:27 for some prophetic words from President Gerald Ford about the future of cooperation in space)

There was a bit of excitement up on the ISS this week. Early on Thursday morning, Houston time, flight controllers in charge of monitoring the trajectory of the ISS were notified of a debris threat without enough notice to coordinate a debris avoidance maneuver rocket firing. Thus, the crew of Expedition 44 had to execute what is called a “shelter in place”. Essentially, they hunker down in their return capsule until the all clear call. No actual debris strike was noted at the “time of closest approach”.

In less scary ISS news, several sets of cubesats were launched from one of the ISS robotic arms. The spring-loaded launcher was built by the company Nanoracks and the cubesats came from various sources, including one test flight for the asteroid mining company Planetary Resources.

Nanoracks recently announced they will also work with Blue Origin to help them fly suborbital research, building on their experience on the ISS.

The next crewed launch to the ISS from Baikonaur will be on Wednesday, July 22nd. You can see NASA TV’s launch and docking coverage schedule here.

There were two successful orbital launches in the last week, both on Wednesday, the 15th: an Atlas V rocket launched a GPS satellite from Florida and an Ariane 5 rocket launched two satellites (one communication and one earth-observing) from Korou.

Around the Solar System

Of course, I can’t resist discussing Pluto at least a little bit… On Tuesday, July 18th, the NASA New Horizons probe made its closest approach to Pluto and survived, phoning home later that evening. The entire dataset from the flyby will take months to downlink back to mission control over the Deep Space Network, but the initial photographs of both Pluto and its largest moon Charon are enough to surprise and excite scientists with some odd unexpected features on both bodies. Some are calling this a “last first look” now that all the large bodies of the solar system have been photographed up close by spacecraft.
