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.

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.

Astronomers at an observatory in Chile have discovered an unusual exoplanet orbiting a dwarf star. The planet is larger than Jupiter and is 25% the size of its host star, the highest known planet-to-star ratio yet discovered.

The Pan-STARRS-1 observatory in Hawaii detected a small rocky body hurtling into our solar system from interstellar space. The asteroid (or should it be called something else?) poses no risk to Earth. Follow the link for a cool animation of its orbit.

The ISS Expedition 53 crew completed the second and third spacewalks in their October series. All planned tasks were completed successfully, leaving the space station with some new cameras and a repaired robotic arm. The rest of the year on ISS will be focused on science research, with some critical deliveries onboard a Cygnus resupply and SpaceX Dragon resupply.

Since my last post on October 9th, there have been four orbital rocket launches:

  • October 11 – SpaceX launched a Falcon 9 rocket carrying two geostationary communication satellites. The first stage was a previously flown booster and was recovered on a droneship.
  • October 13 – A Russian Rokot launched carrying an Earth obesrvation payload for ESA.
  • October 14 – A Soyuz rocket launched from Baikonaur carrying an unmanned Progress resupply bound for the ISS.
  • October 15 – ULA launched an Atlas V rocket carrying a national security payload for the NRO.

The Progress freighter docked successfully two days after launch.

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.

Two rocket launches since my last post, both from Baikonaur Kazakhstan:

First, a Russian Proton rocket launched a Latin American communications satellite.

Then a Soyuz rocket carried three crew members to the International Space Station: Alexander Misurkin, Mark Vande Hei, and Joe Acaba. They joined their Expedition 53 crewmates early last week to make a full crew of 6 onboard.

The incomparable Cassini probe ended its mission this past Friday with a planned suicide dive into the clouds of Saturn. The probe was launched in 1997 and was one of the most successful planetary missions of all time, but it had finally run out of fuel.

One of Cassini’s last acts was a flyby of the moon Titan. Here are some pictures.

The Trump Administration has named Oklahoma Congressman Jim Bridenstine as their nominee for NASA administrator.

The Chinese and European astronauts conducted a joint survival training exercise off the coast of China.

Sierra Nevada Corporation conducted a “captive carry” flight of their Dream Chaser spaceplane.

Last week an ESA Ariane 5 rocket had a pad abort. The agency is still investigating.

The Dragon capsule launched two days earlier docked with the ISS on August 16th.

The day after the cargo. arrival, cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy conducted a successful spacewalk to do space station maintenance as well as some small satellites deployments.

Then on September 3rd a Soyuz returned to Earth, safely carrying Jack Fischer, Peggy Whitson, and Fyodor Yurchikhin to the steppes of Kazakhstan. Both Yurchikhin and Whitson now have accumulated over 600 days in space.

Meanwhile on the ground, a dedicated team of flight controllers was riding out Hurricane Harvey in Houston’s Mission Control Center to ensure the successful undocking and return of the crew.

Speaking of hurricanes, the ISS crew has taken some incredible imagery of Irma has it makes its way across the Caribbean and now Florida.

Lots of launches while I was out. Here’s a worldwide rundown:

Rocket Lab released some information about their failed test launch last month. It turns out the issue was due to some ground segment hardware and they should be able to recover and continue with another test launch soon.

SpaceX is removing the Rotating Service Structure (RSS) at pad 39A at KSC. The RSS was needed for Space Shuttle launches from the historic pad. The RSS from 39B has already been removed in preparations for the SLS program.

The much anticipated launch of the James Webb Space Telescope (JWST) may get delayed from late 2018 into 2019 due to a launch site conflict down in French Guiana, where JWST will be launched on an ESA rocket.

A Japanese rocket launch was cancelled this week due to an unspecified glitch. JAXA was trying to launch a new GPS satellite.

This morning, SpaceX launched a Falcon 9 rocket carrying a Dragon resupply capsule to the ISS. The launch was flawless with a successful first stage landing at Landing Zone 1. The Dragon will rendezvous with the ISS on Wednesday.

Among the cargo on the Dragon capsule is a new experimental super computer, a cosmic ray detector, and a slew of other experiments.

The 6-person Expedition 52 crew is really hitting their stride with their on-orbit photography, with daily Twitter updates to enjoy. The mission will wind down with the return of Peggy Whitson and Jack Fischer in early September, followed shortly by the launch of the second half of the Expedition 53 crew.

On July 2, the Chinese space agency attempted to launch a communications satellite on their heavy lift Long March 5 rocket. Unfortunately, the second stage failed and the payload did not make it to orbit.

On July 5, SpaceX launched a Falcon 9 rocket carrying a commercial communications satellite for Intelsat. The satellite was delivered to geosynchronous orbit. Due to the high performance requirements of the mission, the first stage was disposable, rather than being recovered. This was their 10th launch of the year (the most of any year for SpaceX).

Meanwhile, up on the ISS on July 3rd, the Expedition 52 astronauts unberthed and released the visiting SpaceX Dragon capsule, which splashed down and was recovered that same day.
