Down to Earth

Retired NASA astronaut Terry Virts has published a “coffee table book” of images he took while aboard the ISS during Expeditions 42 and 43.

The 2017 Nobel Prize in Physics was awarded for the discovery of gravitational waves by the LIGO team.

Canadian company MDA has acquired DigitalGlobe and the new merged corporation will be changing their name to Maxar Technologies. MDA is the company that build the Canadarms and DigitalGlobe is a major provider of orbital imagery for users like Google.

In Orbit

Three rocket launches since my last post. All of them occurred today, October 9th:

  • China launched a Long March 2D rocket carrying a Venezuelan satellite.
  • SpaceX launched a Falcon 9 rocket carrying 10 new communication satellites for Iridium.
  • Japan launched an H-2A rocket carrying a native navigation satellite.

Things have been quite busy up on the ISS. Astronauts Mark Vande Hei and Randy Bresnik executed the first of a series of spacewalks last week to maintain the station’s robotic arm. They will go out again tomorrow, October 10th, to continue the work. Here are a few pictures from last week’s EVA:

NASA has announced plans to keep the Bigelow Expandable Activity Module (BEAM) on the ISS for longer than planned and use it as a logistics module.

Out There

A recent study of “Tabby’s Star” using NASA’s orbiting observatories Spitzer and Swift has a new theory for the unexplained dips in brightness: dust. The new hypothesis is compelling because the telescopes detected differences in the dimming at different wavelengths, which implies something transparent like dust.

NASA successfully completed its latest underwater NEEMO mission off the coast of Florida. A crew of astronauts and engineers spent several days in an underwater base testing techniques, gear, and technology for spaceflight. This was the 22nd expedition to the underwater facility.

The Canadian Space Agency announced the selection of their two latest Astronaut Candidates. Jennifer Sidley is a 28-year-old PhD and professor at the University of Cambridge. Joshua Kutryk is a 35-year-old fighter pilot and test pilot with several master’s degrees.

The President of the United States signed an executive order establishing a National Space Council, to guide all of the nation’s endeavours related to spaceflight.

There were five rocket launches since my last post:

Yes, SpaceX had a 48 hour turnaround between two launches, to reach 9 launches on the year. Both first stages were recovered.

In a non-orbital launch, NASA launched an experiment sounding rocket from Virginia’s Wallops Island.

A large satellite in geostationary orbit appears to have broken apart, causing concerns about orbital debris in one of the most important Earth orbits.

Around the Solar System

A recent survey of outer solar system bodies, which found several new distant objects, casts doubt on the hypothesized existence of “Planet 9”. However, the lead researchers of the Planet 9 theory have done their own analysis of the new data, and claim that the data can fit the model. The hunt for Planet 9 continues.

The Curiosity rover is still climbing up Mount Sharp in the center of Gale Crater on Mars. Recently, the MRO spacecraft captured this image of the rover from orbit.

Astronaut Nicole Stott has retired from NASA. She flew to space on Discovery twice with one mission being a long duration stay at the ISS.

The Canadian Space Agency has committed to their partnership in the ISS through 2024. This means that their two unflown astronauts, Jeremy Hansen and David Saint-Jacques, will get to fly expeditions to the station.

Half of the Expedition 43 crew will finally return to Earth this week aboard their Soyuz TMA-15M spacecraft. This will start Expedition 44 with a 3-man crew of Padalka, Kelly, and Kornienko. NASA TV will cover the undocking from ISS on Thursday morning, June 11. The undocking was delayed last month due to the launch failure of an unmanned Progress spacecraft. Due to the extended mission, Samantha Cristoforetti now holds the record for the longest spaceflight by a woman.

On Friday, June 5, a Russian military satellite launched on a Soyuz 2a.1 rocket. This launch is notable because it is the first flight of a Soyuz rocket since the launch failure of the Progress spacecraft. Flights of unmanned Progress and manned Soyuz spacecraft to ISS both launch on the Soyuz family of rockets.

Speaking of Soyuz, check out this awesome timelapse from the TMA-16M docking to ISS earlier this year.

The Planetary Society has confirmed via telemetry that their LightSail’s solar sail has deployed. No photos or video available yet.

Here’s another cool video from a GoPro mounted to the inside of a Falcon 9 payload fairing after a recent launch. The video starts after the fairing has already separated from the rocket.

A new analysis of Hubble Space Telescope data shows that at least two of Pluto’s small moons (Nix and Hyrda) are tumbling unpredictably. Here is a simulation:

It was a bit of a slow week in spaceflight, with only one rocket launch of note and a few bureaucratic developments. Meanwhile, the people of Nepal were hit hard by a major earthquake and over 3,000 are dead. USA Today has a list of charitable organizations (such as UNICEF, Red Cross, World Food Program, and more) that are mounting relief efforts. Here is the link. I gave to American Red Cross.

Down to Earth

NASA’s decision on the next set of contracts for ISS cargo resupply has been delayed until September. This is the re-bid of the contract currently being fulfilled by SpaceX and Orbital ATK.

The US House of Representatives has marked up their first draft of a spending bill for NASA which includes both 2016 and 2017. There is some good news is that the overall NASA budget is going up, pretty much matching the increase requested by the White House. However, the bill from Congress has a significant difference in funding levels for exploration systems and Earth science.

ESA could join NASA’s Europa Clipper mission, planned to launch in 2022, by providing a lander of some kind. Cool!

ABC released a trailer for “The Astronaut Wives Club”. Check it out.

An Ariane 5 rocket launched from French Guiana today with a pair of communications satellites. SpaceX’s next Falcon 9 launch is currently scheduled for tomorrow, from Florida.

Canada has budgeted support of the ISS through 2024 in their latest federal budget. Hooray!

This past week, many in the scientific community celebrated 25 years since the Hubble Space Telescope was launched into orbit. In fact, many not in the scientific community were also celebrating!

With operations planned until at least 2020, Hubble will likely overlap in operations with its successor, the James Webb Space Telescope, scheduled to launch in 2018.

The intriguing bright spots seen by the Dawn spacecraft on the asteroid Ceres have come back into view. Check out this imagery from the mission!
